MEDICAL INSTRUMENT HOLDER
BACKGROUND OF THE INVENTION
In recent years, increased attention has been directed by nnedical
practitioners
and the medical community as a whole to blood borne illnesses and infections.
The
potential for the transmission of blood borne illnesses from patients to
practitioners
has heightened the awareness of safety standards to protect against
inadvertent
practitioner infection. A variety of new safety practices and regulations have
been
developed dictating procedures to be followed before, during, and after
surgery as
well as during the routine care of patients. For example, special procedures
and
cautions are recommended and/oi= required for interactions with. patients
involving
bodily fluids, the handling of inedical apparatus that have been utilized in
connection
with the bodily fluids of patients; and for the disposal of bodily fluids and
other
biological materials.
As a part of the new safety emphasis with regard to blood borne illnesses and
infections, particular attention has been directed to the handling of needles,
trocars, or
other "sharps." Sttch sharps have been a subject of increased focus due to the
potential for accidental puncture of the practitioner's skin and transmission
of disease
to the practitioner. A number of devices have been developed to protect
against
accidental punctures while utilizing sharps. For example, self-deploying
rieedle
shields, which can be readily actuated with limited risk of inadvertent
puncturing of a
practitioner, have been provided on a number of needles and otlier trocar type
apparatus. Specialized depositories for the receipt arid containment of used
needles
have also been developed which provide for safe and simple disposition of
sharps.
Another type of device which has bccn developed to prevent needle sticks or
other punctures of a practitioner is a temporary needle holder. Such temporary
needle
holders are adapted to be utilized in a surgical field for holding a needle or
other sharp
implement that has been utilized or is intermittently utilized during the
course of the
procedure. Such temporary needle holders typically have a instrument holder
field in
which the needles can be inserted while they are not being used. The temporary
needle holder provides a location for the holding of needles that are not
being utilized,
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
2
such that the needles are not left on the surgical surface in a manner that
they may
inadvertently stick or puncture the skin of a practitioner during the course
of the
procedure.
Typically, such temporary needle holders are configured to be fairly small.
Smaller temporary needle holders are typically desired due to surgical surface
ergonomics and the fact that a limited number of needles are typically
utilized in a
procedure. For example, typically. the number and types of surgical tools,
implements, and containers placed in the surgical field for use during the
procedure
are sufficient that a limited amount of space is available for each apparatus.
Due to
lo the limited number of needles that are utilized in typical procedures, a
fairly small
temporary needle holder is sufficient to hold the number of needles needed
during the
procedure. Because a fairly small number of needles are typically. utilized
and the
size requirements for additional needles are quite miniinal, a larger unit is
typically
inefficient due to unused space on the iristrument holder field_ $limination
of unused
space 6n the iristrument holder field typically creates greater efficiencies
in ttsage of
materials, 'storage/shipping size, and per unit weight.
One problem associated with such smaller and/or lighter devices is that where
a practitioner is utilizing a larger needle and syringe combination or where
the 'syringe
is still partially filled with fluid, placeinent of the needle and syringe in
the temporary
needle holder can result in disadvantageous tipping of the temporary needle
holder.
Not only can such tipping be unpredictable, but the tipping can make it
difficult to
utilize the ternporary needle holder and the needles and/or syrixiges
positioried therein
during the course of the procedure. Additioiinally, tipping of a partially
filled syririge
can result in turbulence in the contents of the syringe that rnay introduce
air bubbles
into the syringe. As a result, valuable surgical time may be consumed de-
bubbling the
syringe in preparation for injection of the contents of the syringe into the
patient.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS
As noted above, embodiments of the present invention are generally
concerried with devices for temporarily securing rnedical instruments. In
connection with the disclosed ex'aniple embodiments, it should be noted that
the
terms 'temporary needle holder,' 'sharps holder apparatus,' 'niedical
instrument
holder,' 'needle holder apparatus,' 'instrument holder,' 'temporary
instrumerit
holder' and sirimilar terms are all employed herein in refcrence to devices
that, in
general, are configured to removably retain one or more medical instruments.
Accordingly, the use of the aforementioned terms is riot intended as, nor
should be
c6nstrued as, a limitation on the scope of the claims.
In one example embodiment, disciissed in further detail below in connection
with Figure 1, a lateral surface instrument holder aperture is provided in
additiori to
an instrument holder field in a top surface of the instrument holder aperture.
Tliiis,
smaller instruments, si.uch as needles, can be inserted into the top surface
iristrument
holder field. Larger medical instruments such as larger ineedles, partially-
filled
syringes, scalpels or other sharps can be positioned in the lateral surface
instrument
holder aperture. A portion of the instrument can rest on the support surface
on
which the temporary instrument holder is positioned. Resting of the instrument
on
the support surface minimizes tipping of the temporary instrument holder. When
an instrument is positioned in the lateral surface iristrument holder
aperture, the
instrument is positioned out of the way. of movement of the practitioner,
limiting
disruption, damage, or breakage that may occur from the practitioner
inadvertently
contacting the instrument and/or instrument holder. Additionally; the unique
position of the lateral surface iristrument holder aperture allows a
practitioner to
easily and quickly identify and acquire an instruinent positioned in the
lateral
surface instrument holder aperh.ire.
Figure 1 is a perspective view of temporary needle holder 10, according to one
embodiment of the present invention. In the illustrated embadirnent,
teinporary
needle holder 10 has a lateral surface aperture 20, which is utilized to allow
for
inscrtion of needles into the side of the temporary needle holder 10. Amang
other
things, this arrangement may help to minimize tipping of temporary needle
holder

10. In the illustrated ernbodiment, temporary needle holder 10 includes a top
surface 12, a side surface 14, a instrument holder field 16, a lateral surface
aperti.tre
20; a boundary septunn 22, a rim 24, and a bottom 26. -
Top surface 12 of temporary needle holder 10 includes instrumeint holder field
16. Top surface 12 of temporary needle holder 10 is configured such that it is
facing upward allowing it to be easily viewed and accessed by the
practitioner.
Targets 18 arc positioned in the instrument holder field 16 to provide 'a
visual
identification of potential placement areas for needles, trocars, or other
sharp
implements or tools that have been utilized during the course of the
procedure. A
practitioner can insert smaller and/or lighter needle apparatus, such as
needle tips,
emptied syringes, or an IV trocar into top surface 12.
During the course of the procedure, it is not uincoinmon that relatively
larger
medical devices such as larger needles, syringes, trocars, scalpels or othor
sharp
implements may be utilized. Additionally, it is not uncommon that a partially
filled syringe might need to be inserted into the teniporary needle holder 10
during
the course of the procedure. Lateral surface aperture 20 is positioned in the
side
surface 14 of the -temporary needle holder 10 in a mariner that the
practitioner can
insert larger and/on ccavier needles aind other sharp implements into ths
lateral
surface aperture 20. Lateral siarface aperture 20 provides not only a
supplementary
instrument holder field for insertion of' sharps devices, but is also
positioned
relatively closer to the surgical surface, allowing the irimplernent to rest
on the
surgical surface and minimize tipping of the temporary needle holder.
Boundary septum 22 is positioined adjacent a'lateral side of instrument holder
field 16. In one embodiment, boiundaiy septum 22 comprises a hardened layer or
other puncture impervious or puncture resistant layer, such as plastic,
riietal or
other suitable inaterial, configured to prevent the passage of the tips of
needles,
trocars, or other sharp implements from the instrument holder field to
the.lateral
surface apertiure. Boundary septum. 22 minimizes migration of needle tips into
adjacent instrtiument holder fields that may cause damage to the medical
instruirnents. Boundary septum 22 also limits the passage of needle tips from
instrument holder field 16 to lateral surface aperture 20, or from lateral
surfat;e
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355

aperture 20 to instrumerit holder field 16 so as to reduce the likelihood of a
puncture or otller break of the practitioner's skin. In this way, boundary
septum 22
may prevent injury to the practitioncr that might otherwise result from
inadvertent
contact with a sharp instrument.
kim 24 is positioned to provide an outer boundary for instrument holder field
16. Rim 24 creates a slight recess between top surface 12 of a temporary
needle
holder 10 and the elevation of instrument holder field 16. In this maniner,
rim 24
prevents inadvertent slipping of needles, sharps, or other implement from the
top
surface of the instrument holder field 16 to the exterior of the temporary
rieedle
holder 10. In this manner, a practitioner can safely grasp the temporary
needle
holder 10 and insert a needle inta the instrument holder field 16. In the
event that
the needle slips or does not entirely puncture the instrument holder field 16,
the tip
of the needle will typically be caught by rim 24, preventing uriexpected
slipping
and consequent puncturing of the skin of the practitioner.
Bottom 26 is positioned on the side of temporary needle holder 10 opposite
top surface 12. Bottom 26 is configured to be positioned on a surgical or
other
medical work surface on which the te.mporary needle holder 10 is to be
utilized. In
one embodiment, bottom 26 includes a non-slip surface or adhesive surface
which
facilitates contact of the temporary needle holder 10 with 'the surgical
surface and
additionally prevents tipping of the temporary needle holder 10.
As will be appreciated by those skilled in the art, a variety of types and
configurations of temporary needle holder can be provided without departing
from
the scope and spirit of the present invention. For example, in one embodiment,
a
different nuinber and configuration of targets are provided in the instrument
holder
field. In another embodiment, the lateral surface aperture is of a different
size,
shape and/or configuration than indicated in Figure 1. . In another
embodiment, the
temporary instrument holder field may not include a boundary septum.
Figure 2 is a perspective view of the temporary needle holder 10 of Figure 1,
illustrating a needle syringe combination 30 inserted into lateral surface
aperture
20. In the illustrated embodiment, a syringe pbrtion of needle syringe
combiriation
30 is partially filled with a fluid 32. Fluid 32, positioned in the syringe
portion of
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
needle syringe combination 30, substantially adds to the weight of needle
syringe
combination 30. Additionally, the length of the needle portion of the needle
syringe combination 30 creates a higher center of gravity, which can add to
the
likelihood of tipping of temporary needle holder 10 should needle syringe
5 combinatioin 30 be positioned or inserted in instrument holder field 16.
Additionally, a practitioner may simply desire to, position needle syringe
combination 30 in a separate location away from other needles or sharp
implements. By providing a separate location for the insertion of needles and
other
sharps implements, instrument holder field 16 can also help to more readily
10 identify needle syringe combination 30 as an implement which the
practitioner may
desire to utilize later in the procedure being performed.
In the illustrated embodiment, needle syririge combination 30 is inserted in
lateral surface aperture 20. Needle syringe com.bination 30 is showii
positioned at
a slight angle, such that the rearward portion of needle syringe combination
30 is in
contact with support surface 28.. By being in contact with su:pport surface
28,
needle syringe combination 30 is sufficiently supported to prevent breakage,
or
other damage, of needle syringe combination 30. Additionally, needle syringe
combination 30 is supported in a manner that minimizes tipping of terrmporary
needle holder 10. In this manner, a desired and intended positioning of
temporary
needlc holder 10 is maintained, allowing a practitioner to quickly identify
instrument holder field 16 for the insertion of additional needles; sharps, or
other
tools or implerrients, and also to quickly identify the positioning of lateral
sixrface
aperture 20 and needle syringe combination 30 positioned therein.
Figure 3 is a side view of temporary needle holder 10, illustrating a top
needle
holder cushion layer 34 in phantom lines. It should be noted that various
types of
cushion layers may also be referred to herein individually and collectively as
simply a'etishion layer' or 'cushioii layers,' respectively.
The positioning of top needle holder'cushion layer 34 relative to lateral
surface
aperture 20 is also shown. As- previously discussed, lateral surface aperture
20 is
positioned in side surface 14 of terr-porary needle holder '10. Top needle
holder
cushion layer 34 represents the total volume of the cushioin layer associated
with a
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
11
instrument holder field that is available to receive needles, trocars, or
other sharp
implements from the instruinent holder field.
In the illustrated embodiment, top needle holder cushion layer 34 extends a
depth into temporary needle holder 10 which at least corresponds to, and may
even
extend beyond, the location of lateral surface aperture 20. Boundary septum 22
runs from top surface 12 of temporary needle holder 10 to the bottom 26 of
temporary needle holder 10. In this manner, boundary septum 22 provides a
complete and effective boundary to prevent the passage of needles, or other
sharps,
from rieedle holder cushion layer 34 to lateral surface aperture 20.
In the illustrated embodiment, the material from which top needle holder
cushioin layer 34 is formed comprises a rion-coring resilient foam material.
The
non-coring quality of cushion layer 34 allows a needle to be insc"rted into
top
needle holder cushion layer 34 and withdrawn without leaving a noticeable
hole.
In this nianner, a secondary implement can be reinserted into the saine
position
withoiut weakening or minimizing the ability of cushion layer 34 to retain the
secondary implement, subsequent, to the earlier insertion. Other materials.of
comparable functionality and characteristics may be employed.
As will be appreciated by those skilled in the art, a variety of types and
configurations of temporary needle holder can be utilized without departing
from
the scope and spirit of the present invention. For ekample, in one enibodiment
the
boundary septum extends only a portion of the length from the top surface of
the
needle holder cushion layer to the bottom of the needle holder cushion layer.
ln
another embodiment a variety of types and configuratioin of cushion 'materials
are
be utilized. For eacainple, in or-e embodiment, a thermalplastic rubber layer
can be
utilized. In another embodiment, another resilient polymer-based material can
be
utilized. In another embodimcnt, sinall layers of foam can be positioned
adjacent
one another in a inanner to retain a needle or other sharp implement.
Figure 4 is a top view of the temporary needle holder 10 illustrating the
juxtaposition of the side needle holder cushion layers 36; 38 relatiwe 'tb the
instrument holder field 16. In the illustrated einbodiment, side needle holder
cushion layers 36, 38 are positioned.on two sides of instrument holder field
16.
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
12
Side needle holder cushion layers 36, 38 extend along the length of the Outer
boundary of the instrument holder field 16. As explained with reference to
Figure
3, boundary septixm 22 provides an 'effective barrier between top needle
holder
cushion layer 34 and side needle holder cushion layers 36 and 38. By virtue of
the
first and second side needle holder cushion layers 36, 38, a praotitioner can
insert
more than one implement into a lateral surface aperture. This allows the
plaeeinent
of multiple syringes in the event that multiple syringes may need to be
utilized
during the course of the procedure or in the event that multiple heavy
needle/syringe.combinations or other implements are utilized..
Figure 5A is a top cross-sectional view of a temporary needle holder 10
according to one embodiment of the present invention. In the illustrated
embodiment, the tips of needle syringe combinations 30a and 30b are inserted
into
side needle holder cushion layers 34 aiid 36, respectively. In the illustrated
embodiment, it can be seen that the length of the needle syringe combinations
30a
and 30b are sufficiently long that, in the absence of boundary septums 22a,
22b, the
needles could extend from the side needle holder cushion layers 36, 38 and
into the
top needle holder cushion layer 34 and out of the associated instrument holder
field
16 (see also Figure 5B).
Use of side needle holder cushion layers 36, 38 provides two additional points
of placement for needles, trocars, or other sharp implements, in addition to
the
instrument holder field 16 (see Figure 1). Side needle holder cushion layers
36, 38
aind their associated lateral apertures allow the practitioner to more easily
keep
track of particular needles, syringes, and associated medicinal fluids
cointained
therein, to be utilized in subsequent portions of the procediire.
Additionally, the
needles 30a and 30b can rest on the support surface on which the temporary
ncedle
holder 10 is positioned. This minimizes potential breaking of the tips of the
needles 3Oa, 30b while also minimiziiig tipping of the temporary needle holder
10.
In the illustrated embodiment, boundary septum 22a extends along the entire
length
of temporary needle holder 10, such that the tip of needle syringe combination
30b
30is prevented from contacting the tip of needle syringe combination 30a in a
manrier
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
13
that may cause damage, the exchange of fluids, or.other contamination of
needle
syringe combination 30a from needle syringe combination 30b.
Figure 5B is a cross-sectional side view of a temporary needle holder 10 in
which needle tips 40a and 40b have been inserted into a top needle holder
cushion
layer 34. In the illustrated embodiment, it can be seen that rim 24 of
temporary
needle holder 10 extends above the top surface of the instrument holder field
16.
Needle tips 40a and 40b have been iriserted irito top needle holder cushion
layer 34,
such that the distal ends of the needle tips 40a and 40b extend a given amount
into
the top needle holder cushion layer. The length of needle tip 40a is
stibstantially
lo longer than that of needle tip 40b. It can.be appreciated that, in the
absenee of a
boundary septum 22 and in the event that needle tip 40a is inserted at an
angle into
top needle holder cushion layer 34, the point of needle tip 40a could extend
out
through the side needle holder ct-shion layer 36 and associated lateral
surface
aperture 20 (see Figure 1) in a manner that could result in inadvertent
sticking or
puncture of the practitioner who may be holding the teniporary needle holder
10.
As will be appreciated by those skilled in the art, a variety of types and
configurations of the temporary needle holder can be provided without
departing
from the scope and spirit of the present invention. For example, in one
embodiment, the shape of the temporary needle holder is rectangular. In
another
embodiment, the shape of the temporary needle holder is other than a square or
rectangle. In another embodiment, the sides of the needle holder cushion
layers
coinpletely fill the inside of the temporary needle holder, such that the
needle
holder cushion layers are only bounded by the outside edges of the teinporary
needle holder and the boundary septa.
Figure'6A is a perspective view of an alternative embodiment of the preserit
invention. In the illustrated embodiment, a first lateral surface aperture 20a
and a
second lateral surface aperture 20b are positioned in the side surface 14 of
the
temporary needle holder 10. In the illustrated embodiment, first lateral
surface
aperture 20a is positioned above second.lateral surface aperture .20b.
'Second.
lateral surface aperhzre 20b is larger than first * lateral surface aper"ttire
20a. This
allows larger needle syringe combinations to be placed in second lateral
surface

aperture 20b. As a result, a smaller needle syringe combination inserted into
first
lateral surface aperture 20a can rest directly on a larger needle syringe
combixiation
placed in second lateral surface aperture 20b. A plurality of lateral surface
apertures can be provided in the same side surface of terriporary needle
holder 10,
providing additional placement locations and potential sharps device
organization
by the practitioner during the course of the procedure.
Figure 6B is an illustrative view of a temporary needle holder 10A, according
to one embodiment of the prescnt invention. Iri the illustrated embodiment, a
instrument holder field 16a having two targets 18a is positioried in a top
surface 12
of the temporary needle holder 10A. A lateral surface aperture 20a having two
targets 18b is positioned in a second side surface 14 of terriporary needle
holder
10A. A second lateral surface aperture 20b having two targets 18c is
positioned in
a third side surface 15. In this manner, both primary and secondary surfaces
on the
temporary needle holder are provided with substantially identical instrument
holder
fields that can be utilized as desired by the practitioner. An arrangement as
presently illustrated, in which the configuration of the instrument holder
fields are
substantially the same, while being provided at different locatioris on the
temporary
needle holder, can be desirable where a procedure requires the organization
and/or
reuse of many similar sharp implements. Alternatively, a plurality of sharp
2o implements which simply require repeated use and safe disposition
throughout the
course of the procedure may be utilized. According 'to one embodiriient of the
present invention, all or substantially all of the surfaces of the temporary
needle
holder are provided with a instrument holder field, such that in the eveint
that the
temporary needle holder is tipped, a instrument holder field is readily
available for
the disposition of needles, trocars, or other sharp iinplerients that need to
be
disposed of
According to one embodiment of the present invention, the temporary needle
holder 10A is configur"ed such that subsequent to the completiori of the
procedure,
the entire temporary needle. holder 10A can be discarded without needing to
remove the needles that have been inserted therein. In this manner,
theternporary
needle holder 10A provides not only a safety mechanism for use during the
course
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
of the procedure, but also a quick, safe, and effective mechanism for
disposing of
the sharps subsequent to the completion of the procedure. Because lateral
surface
apertures 20a and 20b allow for the positioning of heavier rieedles,
sy,ringes,' tools,
or other impleinents, the temporary needle holder 10A funotions not only as a
5 sharps receptacle for smaller needle tips or lighter syringes, but also as a
depository
for all potentially sharp implements that may need to be discarded subsequent
to
the completion of the procedure.
Figure 7 is a perspective view of a temporary instrument holder 110,
according to another embodiment of the invention. In the illustrated
embodiment,
10 temporary instrument holder I 10 has a lateral surface aperture 120, which
is
utilized to allow for insertion of medical instruments, such as needles;
trocars,
scalpels or other devices or implements, into the side of temporary
instrttment
holder 110. Insertion of such medical instruments. into the side of tcmporary
instrument holder 110 helps to reduce tipping of terriporary instrument holder
110.
15 In the illustrated embodim.ent, temporary instrument holder 110 iricludes a
body
111, a lid 113, a top surface 112, side surfaces 114, a instrument holder
field 116,
lateral surface aperture 120, a rim 124, a bottom 126, top instrument holder
cushion
layer 134, and lateral instrument holder cushion layer 133.
In one embodiment, body 111 of temporary instrument holder 110 provides a
housing for instrument holder field 116. In the illustrated embodimeint, body
111
comprises a generally box-like structure having side surfaces 114, rim 124 and
bottom 126. Body 111 can be made of any suitable material, such as plastic or
some other polymer. In the illustrated embodiment, lid. 113 is.linked to a
side
surface of body 111 via a hinge-type connection. 'Lid 113 is configured to
enclose
instrument holder field 116 when lid 113 is closed and positioned adjacent rim
124.
The outer boundary of lid 113 may be sized to correspond and mate with rim
124.
Furthermore, lid 113 and body 111 may include a latching device to
substantially
secure lid 113 to body 111.
In one embodiriient, lid 113 is configured and.sized such that its depth is
sufficient to allow needle tips 140a and 140b to be positioned in instrument
holder
field 116 with lid 113 closed without having the needle tips 140a and 140b
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
16
interfere with the complete closure of lid 113. In this manner, after a
practitioner
has disposed of various medical instruments, such as needle tips, the
practitioner
may close lid 113. Closing lid 113 encloses the needle tips in instrument
holder
field 116 to in turn reduce the risk of accidental puncture of the
practitioner by the
disposed medical devices. When lid 113 is closed, lid 113 may effcctively
serve as
a boundary septum for lateral surface aperture 120: In some other embodiments,
lid
113 may include additional instrument holding fields.
Top surface 112 of temporary instrument holder 110 includes instrument
holder field 116. Top surface 112 of temporary instrumerit holder 110 is
configured such that it is facing upward allowing it to be easily viewed and
accessed by a practitiorier when lid 113 is open. A plurality of targets 118
are
positioned in instrument holder field 116 to provide a visual identification
of the
potential placement areas for medical instrumeints, such as needles, trocars,
scalpels
or other sharp implements or tools that may be utilized duiring the course of
a
procedure. A practitioner can insert sinaller and/or lighter needle apparatus,
such
as needle tips, emptied syringes, or an TV trocar into top surface 112.
Lateral surface aperture 120 is positioned in side surface 114 of temporary
instrument holder 110 in a manner that the practitioner can insert larger
and/or
heavier medical instruments such as a scalpel, a needle syringe combination,
or
some other sharp implement, into lateral siurface aperture 120. Lateral
surface
aperture 120 provides not only a supplementary instrument holder field for
insertion of sharp devices, but is also positioned closer to the surgical
surface,
allowing for resting of the riledical instrument on the surgical surface and
thereby
minimizing tipping of temporary instrunilent holder 110. Lateral surface
aperture
120 is one example of a feature enabling insertion of a needle or other sharp
device
into a second side of the temporary instrument holder.
In the illustrated embodiment, lateral surface aperture 120 is rectarigular in
shape. The shape and config-uration of lateral surface aperture 120 enables a
variety of types, shapes and sizes of irnplements to be inserted therein. The
size
and configuration of lateral surface aperture 120 may be adjusted to
accommodate
for the size and configuration of various medical imlalements.,
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
17
For example, in the illustrated embodiment, a scalpel 131 has been inserted in
lateral surface aperture 120. The positioning of scalpel 131 in lateral
surface
aperture 120 facilitates the contact of scalpel 131 with a support surface. By
contacting the support surface, scalpel 131- helps to reduce tipping of
temporary
instrument holder 110. Tn this manner, desired aind intended positioning of
temporary instrument holder 110 is maintained. 11Qoreover, a practitioner is
thius
able to quickly identify instrument holder field 116 for the insertion of
additional
medical instruments 'such as needles, sharps or other tools or implements,
while
also being able to quickly identify the positioning of lateral surface
aperture 120
and scalpel 131 positioned therein.
Rim 124 is positioried to provide an outer bouridary for instrument holder
field '
116. Rim 124 creates a slight recess between top surface 112 of temporary
instrument holder 110 and the elevation of instruriment holder field 116. In
this
manner, rim 124 preveiits inadvertent slipping of sharp rnedical iristruments
from
top surface 112 of instrumeint holder field 116 to the exterior of tenriporary
instrument holder 110. Thus, a practitioner can safely grasp temporary
instrument
holder 110 and insert a needle or other medical instrument into instrument
holder
field 116. In the event that the needle or some other medical instrument slips
or
does not entirely puncture instrument holder field 116, the tip of the medical
instrument will typically be caught by rim 124. This catching generally
prevents
additiorial slipping and puncturing of the practitioner.
Bottom 126 is positioned on the side of temporary instrument holder 110
opposite top surface 112. Bottom 126 is configured to be positioned on a
surgical
or other medical work surface on which teinporary instrument holder 110 is to
be
utilized. In one embodiment, bottom 126 includes a non-slip surface or
adhesive
surface which facilitates retention of temporary instrument holder 110 on the
surgical surface aind additionally prevents tipping of temporary instrumeirnt
holder
110.
In the illustrated embodiment, lateral instrument holder cushion layer 133
extends a depth irito temporary instrument holder 110. The size of the lateral
instrument cushion layer 133 may correspond with, and even extend beyond, the
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
18
location of lateral surface needle aperture 120. In this embodimeint, lateral
iristrument holder cushion layer 133 substantially fills the volume of body
111
below rim 124. In this manner, needles or scalpels or other sharp implements
which are inserted into instrument holder field 116 and/or lateral surface
apertu.re
120 are inserted into instrument holder cushion layer 133.
In the illustrated embodiment, the material from which lateral instrument
holder cushion layer 133 is fornied comprises a non-coring resilicnt foam
niaterial.
The non-coring quality of instrument holder cushion layer 133 allows a needle
to
be inserted into instrument holder cushion layer 133 and withdrawn without
leaving a noticeable hole. Thus, another implement can be subsequently
inserted
into the same position in instrument holder cushion layer 133 without
weakening or
minimizirig the. ability of instrument holder cushion, layer 133 to 'retain.
that
implement.
As will be appreciated by those skilled in the art, a variety of types and
configurations of temporary instrument holders can be utilized without
departing
from the scope and spirit of the present invention. In one embodiment, a
variety of
types and configurations of cushion niaterials may be utilized. For example,
in
one erimbodiment, a thernioplastic rubber layer can be utilized. In another
einbodiinent, another resilient polymer-bascd material can be utilized. In
another
embodiment, sinall layers of foam can be positioiied adjacent one another in a
manner to retain a needle or other sharp implernent. Figure 8 illustrates an
alternative embodirnent of temporary instrument holder
110. In this embodimeiat, a first lateral surface aperture 120a and a. second
lateral
surface aperture 120b are positioned in side surface 114 of the temporary
instrument holder 110. In the illustrated etnbodinient, first lateral surface
aperture
120a is positioned to the side of second lateral sixrface aperhu-e 120b: First
laferal
surface aperture 120a is larger and a different shape than second lateral
surface
aperfiure 120b; first lateral surface aperture 120a is rectangular and second
laterat
surface aperture 120b is circular. This enables different types and sizes of
medical
implements to be placed in either the first or second lateral surface
apertures 120a'
and 120b, respcctively. For exatnple, an implement, such as a scalpel, may be
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
19
inserted into first lateral surface aperture 120a and a needie combination may
be
placed in second lateral surface aperture 120b. A plurality of lateral surface
apertures may be provided in the same side surface of temporary instrument
holder
110, piroviding additional placement locations and poteritial sharps device
organization by the practitioner during the course of the procedure.
Further illustrated in Figure ~ 8 is a boundary septum 122 separating lateral
surface apertures 120a and 120b froin instrument holder field 116. In one
embodiment, boundary septum 122 runs from top surface 112 of teniporary
instrument holder 110 to bottom 126 of temporary instrument holder 110, and
extends from one side of body 111 to the opposing side of body 111. In this
rnanner, boundary septum 122 may provide a complete and effective boundary to
prevent the passage of sharps from instriunent holder cushion layer 134 to
lateral
surface apertures 120a and 120b.
In the illustrated embodiment, instrument holder field 116 comprises a top
instrument holder cushion layer 134. In this embodiment, top iristrumerit
holder
cushion layer 134 is rectangular shaped to correspond to a portion, of body
111
defined by three side surfaces of body 111, bottom 126 and boundary septum
122.
Lateral surface apertures 120a and 120b comprise a side instrument holder
cushion
layer 138. In the illustrated einbodiment, side instrument holder cushiori
layer 138
substantially fills the volume of body 111 defined by three side surfaces 114,
bottom 126 and boundary septunis 122.
As will be appreciated by those skilled in the art, a variety of types and
configurations of temporary instrument holders may be utilized without
departing
from the scope and spirit of the present invention. For example, in ohe
embodiment the boundary septum extends ornly a portion of the length from the
top
surface of the instrument holder cushioin layer to the -bottom of the
instrument
holder cushion layer.
I igurc 9is an illustrative view of a temiporary instrument holder 110,
according to one embodiment of the invention: In the illustrated embodixinent,

instrument holder fields 116a and 116b positioned in top surface 112 of
teinporai'y
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
instrumerit holder I10 and first and second lateral surface apertures 120a and
120b
positioned in opposing side surfaces 114 of temporary instrument holder 110.
in
this embodiment, each of first and second instrument holder fields 116a and
116b
are positioned proximate opposing corners of body 111. Likewise, each of first
s and second lateral surface apei=tures 120a and 120b may be positioned in
opposing
corners of body 111.
A first boundary septum 122a separates first lateral surface aperture 120a
from -
first instrument holder field 116a, second instrument holder field 116b and
second
lateral surface aperture 120b. In one embodiment, first boundary septum 122a
runs
10 from top surface 112 of temporary instrument holder 110 to bottom 126 of
temporary instrument holder 110. In this manner, first boundary septum 122a
may
provide a complete and effective boundary to preVent the passage of scalpels,
needles, sharps, or other implements'between first lateral surface apertiure
120a and
first and second instrument holder fields 11 6a and 116b and second lateral
surface
15 aperture 120b.
A secorid boundary septum 122b separates second lateral surface apertitre
120b from first instrument holder field 116a, second instrument holder field
116b
and first lateral surface aperture 120a. In one embodiment, second boundary
septui-n 122b runs from top surface l 12 of ternporary instrument holder 110
to
20 bottom 126 of temporary instrument holder 110. In this manner, second
boundary
scptum 122b may provide a complete and effective boundary to prevent the
passage of scalpels, needles, sharps, or other implements between secoiid
lateral
surface aperture 120b and frst and second instrument holder fields 11 6a and
11 6b
and first lateral_surface aperture 120a. In this embodiment, four separate
cushion
layers are provided - one for each of the first and second instrrtineint
holder fields
116a and 116b and one each for the first and second lateral siurface apertures
120a
and 120b.
Further included in the embodiment of Figure 9 are a third lateral surface
aperture 120c and associated third boundary septum 122c, and a fourth lateral
surface aperture 120d and associated fourth boundary septum 122d in lid 113.
In
the illustrated embodiment, third boundairy septum 122c may provide a complete
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
21
boundary to prevent the passage of sharps such as scalpels, needles, or other
implements from third lateral surface aperture 120c. Likewise, fourth boundary
septum 122d may provide a complete boundary to prevent the passage of
scalpels,
needles, sharps, or other iinplemeiits from fourth lateral surface aperture
120d. The
positioning of third and fourth lateral surface apertures 120c and 120d in lid
113
provides additional locations for a practitioner to place medical implements
while
not in use. Furthermore, positioining of third and foiirth lateral surface
apertures
120c and 120d in. lid 113 enables a practitioiier to effectively utilize the
space of
temporary instrument holder 110.
An arrangement as presently disclosed may be desirable where a procedure
requires the organization and/or reuse of many . similar sharp implements.
Alternatively; a plurality of sharp implements which simply require repeatcd
use
and safe disposition throughout the course of the procedurc may be utilized.
According to one einbodiinent of the present invcntion, all or siubstantially
all of
the surfaces of the temporary instrument'holdcr are provided with a instrument
holder field, such that in the event that the temporary instrument holder is
tipped, a
instrument holder field is readily available for the disposition of needles,
trocars, or
other sharp impleineints that need to be disposed.
According to some embodiments of the present invention, subsequent to the
completion of the procedure, the entire temporary instrument holder 110 may be
discarded as a unit, including any used instruments inserted into temporary
instrument holder 110. This allows the disposal of contamiriated instruments
without necessitating the removal of needles and/or instruments that have been
inserted into the temporary instrument holder 110. Thus, temporary instrument
holder 110 provides not only a safety mechanism for.use during the course of
the
procedure, but also a quick, safe, and effective mechanism for disposing of
the
sharps subsequent to the completion of the procedure. Because lateral surface
apertures allow for the positioning of heavier needles, syringes, tools, or
other
irimplements, temporary instrument holder 110 functions not only as a sharps
receptacle for smaller needle tips or lighter syringes, but also as a
depository for all
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
22
potentially sharp implements that may need to be discarded subsequent' to the
completion of the procedure.
As will be appreciated by, those of skill in the art, a variety of types. and
configurations of temporary instrument holders can be provided without
departing
from the scope and spirit of the present invention. For example, in one
example
embodiment, a different number and configuration of targets are provided in
the
instrument holder field. In ariother example embodiment, the lateral surface
aperture is of a different size, shape and/or configuration. In another
example
embodiment, the lid is sized and configured so as to enclose both instrument
holder
to field and lateral surface aperture.
With attention now to Figures 10A and lOB, various elements of a sharps
holder apparatus, according to one exarriple embodiment of the present
invention,
are disclosed. In the illustrated embodiment, the sharps holder apparatus 200
comprises a housing 201, a top surface cushion layer 226, and a side-surface
cushion layer 228. Top surface cushion layer 226 and side surface. cushion
layer
228 can be positioned within housing 201 to provide a mechanism for capturing
sharps such as needles, syringes, trocars, scalpels or other sharp medical
implements that may be utilized within the surgical field. Housing 201 may
provide a mechanism for accommodating. and securing top surface cushion layer
226 and side surface cushion layer 228 in a manner that allows for securement
of
the sharps by cushion layers 226 and 228.
In the illustrated embodiment, housing 201 may include an outer wall 202, a
first cavity 204, a second cavity 206, a boundary septum 207, a top surface
aperture
208, a side surface aperture 210, and a moveable bottom member 215.
Outer wall 202 can define the outer bolindary of housing 201 and provides a
secure framework in which top surface cushion layer 226 and side surface
cushion
layer 228 can be positioned. Outer, wall 202 partially defines a first cavity
204 and
a second cavity 206. First cavity 204 may have a substantially square
configuration having a depth conf gured to accoinmodate top surface cushiori
layer
226. Second cavity 206 inay have a depth and size to accommodate second side
surface cushion layer 228. Boundary septum 207 6an separate first cavity 204
from
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
23
second cavity 206. Utilizing a boundary septuixi 207 prevents passage of a
trocar,'
needle; or other sharp implement between top surface cushion layer 226 and
side
surface cushiorn layer 228.
As illustrated, housing 201 may include a top surface aperture 208 and side
surface aperture 210. Top surface apertuie 208 is defined by the top surface
of
housing 201. Side surface aperture 210 may be positioned on the side surface
of
housing 201. When sharps holder apparatus 200 is fully assembled and resting
on
the surgical surface, top surface aperture 208 may theri be positioned upward
allowing rieedles, trocars, or other instruments to be inserted therein, as
illustrated
in Fig. 11B. As shown in Fig. 10A, side surface aperture 210 may be positioned
on
the side of the needle holder apparatus in'a manner siu.ch 'that heavier or
larger
implements, such as a fluid-filled syririge 242 (Fig_ 11B), a scalpel 256
(Fig. 12),
or other implement can be positioned in the side surface cushion layer .228
while
the instrument, trocar, or other apparatus can rest on the table or. other
surgical
surface in manner to prevent tipping of the needle holder apparatus.
A top rim contact surface 212, top barrier surface 214, and side rim contact
surfaces 250 are also illustrated. Top rim contact surface 212, top barrier
surface
214, and side rim contact surface 250 facilitates proper positioning and
securement
of top surface cushion layer 226 and side surface cushion layer 228 during
assembly. For example, when top surface cushion layer 226 is positioned in
first
cavity 204, top surface cushion layer 226 may be slid into first cavity 204
u.ntil the
outer rini of the upper surface of top surface cushion layer 226 cointacts rim
contact
surface 212. Contact surface 212 can stop additional upward movement of top
surface cushion layer 226, and also provides indication to the irser that
further
advancement of the top surface cushion layer is no longer necessary.
Top barrier surface 214 may provide a solid contact surface that also stops
further advancement of side surface cushion layer 228 when side surface
cushion
layer 228 is being inserted into housing 201. Side rim contact surfaces 250
may
maintain.the lateral positioning of side surface cushion layer 228 in second
cavity
206. In this manner, side surface cushion layer may be prevented from
migrating
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
24
out of side surface aperture 210 during assembly or usage of the needle holder
apparatus.
A moveable bottom member 215 is also illustrated. Moveable bottom inember
215 may be configured to be secured to the bottoin periphery of outer wall 202
to
secure top surface cushion layer 226 and side surface cushion layer 228
withiri
their respective cavities 204 and 206. As illustrated, moveable bottoin member
215
may be attached to one side of outer wall 202 using a hinge 217. In this
manner,
the desired positioning 'of moveable bottom inember 215 relative to the other
portions of hoiising 201 may be maintained until the top surface cushion layer
226
and side surface cushion layer 228 have beeii positioned within first cavity
204 and
second cavity 206.
Once top surface cushion layer 226 and side surface cushion layer 228 have
been positioned within housing 201, the user can simply hinge moveable bottom
member 215 into cooperative and locked engagement with the entire bottoria
periphery of outer wall 202. As illustrated, outer wall 202 includes a snap
fit ridge
220 and moveable bottom member 215 includes a* snap fit flange 222. When
moveable bottom member 215 is hinged to a closed position relative to outer
wall
202, snap fit flange 222 biases over snap fit ridge 220 securing moveable
bottom
member 215 in position relative to the other components of housing 201. In
this
manner, top surface cushion layer 226 and side surface cushion layer 228 can
be
secured within hoixsing 201 in * a relatively simple, effective, and cost
effective
manner.
As illustrated, side margin supports 216 and boitoin margin supports 218 may
be provided. Side margin supports 216 comprise a raised ridge, and bottorri
margin
supports 218 comprise raised panels. Side margin supports 216 and bottom
margin
supports 218 may be adapted to contact portions of top surface cushion layer
226
and side surface cushion layer 228. Side margin supports 216 and bottom margin
supports 218 may effectively secure top surfaee cushion layers 226 and side
surface cushion layer 228 within first cavity and second cavity. 204 and 206,
even
when there is a slight margin left by a discrepancy between the size of top
surface
cushion layer 226 and first cavity 204 or side surface cushion layer 228 and
sea6nd
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
cavity 206. In this manner, any gap that is left by a slightly sinaller side
of bushion
layers 226 and 228 may be effectively filled, while allowing for larger
'cushion
layers to also be inserted within first cavity 204 and second cavity 206.
As illustrated, side inargin supports 216 rimay be positioned on the inside of
5 first cavity 204 and second cavity 206. For example, side margin supports
216 can
be provided on each of the four lateral surfaces along outer wall 202 and
boundary
septuin 207. The somewhat narrow and stiffened nature of side margin supports
216 and bottom margin supports 218 may allow for a certain . amount of
deformation of cushion layers 226 and 228 in the event that there is little or
no
10 margin between the sides of the cushion layer and the-respective cavity in
which it
is being positioned. Additionally, the ridged nature of side margin supports
216
and bottom margin supports 218 may allow for securement of tlie cushion la.yer
in
the event that there is a somewhat larger margin betweeti the sides of the
cushion
layer and the respective cavity in whicli it is positioned.
15 Side margin 'supports 216 may be configured to fill latetal discrepancies
in
size betvveen the cushion la:yer 226, 228, and the cavities 204 and 206,
respectively.
Bottom margin supports 218 may be configured to facilitate contact between top
rim contact surface 212 and the top surface cushion layer 226. Similarly,
bottom
margin support 218 may facilitate contact between top barrier surface 214 and
the
20 side surface cushion layer 228.
As illustrated, an adhesive cover strip 224 inay exteiid from the underside of
moveable bottom member 215. Adhesive cover strip 224 includes a tab that cari
be
grasped by a* user facilitating removal of adhesive cover strip 224 frorri the
respective adhesive strip. When positioned on the underside of moveable bottom
25 member 215, adhesive cover strip 224 may secure sharps holder apparatus 200
on a
surgical or other stipport surface, minimizing tipping or inadvertent
moveinent of
the apparatus during a surgical procedure being performed.
Top surface cushion layer 226 and side surface ctishion layer 228 are depicted

surface aperture 208 of housing 201. In this rrianner, top surface 232 can be
accessed by a user for positioning needles, trocars, scalpels, or the like
within the
sharps holder apparatus. The outer periphery of top surface 232 may be
configured
to contact top rim contact surface 212 to secure the positioning of top
surface
cushion layer 226 within housing 201. Top surface cushion layer 226 also
includes
a bottom surface 238. Bottom surface 238 may be configured to be in contact
with
moveable bottom member 215 so that top surface cushion layer 226 is thereby
cooperatively secured between top riin contact surface 212 and bottom surface
238.
In the illustrated embodiment, a plurality of targets 233 of top surface
cushion
layer 226 'are depicted. Targets 233 a:re positioned on top surface 232 of top
surface cushion layer 226. Targets 233 may provide a visual identification
facilitating proper insertion of needles, trocars, or other instruments within
the top

As illustrated, a side siirface cushion layer 228 is also depicted. Side
surface
cushion layer.228 includes a side surface 234, ;a. top surface 236, and bottom
surface 240. As previously discussed, top surface 236 may be configured to be
in
contact with a top barrier surface 214. One of side surfaces*234 may be
exposed to
the external environment by side surface aperture 210. In this manner, a
practitioner, such as a surgeon or nurse for example, can insert a scalpel,
fluid
filled syringe, or other instrument into side surface cushion layer 228. In
this
manner, when moveable bottom member 215 is resting on the support surface, the
instrument positioned within side surface cushion layer 228 can rest on the
surgical
surface in a nianner to prevent tipping of the tieedle holder apparatus or
inadvei-tent
breakage of the instrument positioned within side surface cushiofi layer 228.
Bottom surface 240 may be positioned in coratact with rimoveable bottom
member 215. In this manner, side surface cushion layer 228 may be sandwiched
between top barrier surface 214 and moveable bottom member 215.
As will be appreciated by those skilled in the art, a variety of types and
configurations of the sharps -holder apparatus can be implemented vwithout
departing from the scope and spirit of the present inweintion. For example,
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
27
according to one embodiment of the present invention, a single needle cushion
layer may be provided. -In another embodiment; the rnoveable bottom member may
be locked into place once the sharps holder apparatus has been fully
assembled. In
another embodiment, moveable bottom member may be secured to the needle,
holder apparatus using other than a hinge. In another embodiment, the moveable
bottom meinber may not be secured to the needle holder apparatus but
positioned
in place once the one or more cushion layers have been positioned within the
housing. In yet another embodiment the moveable bottom member -may comprise
a plurality of components, which cooperatively secure one or more cushion
layers
withiri the housing. In yet another'embodiment, one or more side ports may be
provided in addition to a top surface cushion layer.
Figure 11A is a top perspective view of sharps holder apparatus 200 during
assembly. In the illustrated embodiment, top surface cushion layer 226 may be
positioned within housing 201. As previously discussed with reference to
Figures
10A and lOB, top surface cushion layer 226 may be*configured to be positioned
within first cavity 204 (see Figure 10A and lOB). As illustrated, top surface
cushion layer 226 may be fully advanced within housing 201 such that top
surface
cushion layer 226 is accessible through top surface aperture 208. A plurality
of
targets 233 may be seen through top surface aperture 208. In this manner,
potentially desired points of contact between'the needle arnd the iop surface
cushion
layer 226 are clearly displayed to the user. A top rim 252 is also
illustrated. Top
rim 252 may be positioned on the upward facing side of the top rim contact
surface
212 depicted in Figure 10A. Top rim 252 may have a desired amount of elevation
over and above top surface 232 of top surface cushion layer 226.
As illustrated, side surface cushion layer 228 may be fully advanced within
second cavity 206 (see Figure 10A and l OB). Side suirface cushion layer 228
may
be in contact with top barrier surface 214. Additionally, a side rim 254 may
be in
contact with a side surface 234 of side 'surface cushion layer 228. In this
manner,
inadvertent migration of side surface cushion layer 228 out through side
surface
aperture 210 may be prevented. Side surface aperture 210 may provide access to
side surfacc cushion layer 228. In this manner, a practitioner can insert
needles,
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355
28
syringes, scalpels, or other medical devices into the side of the sharps
holder
apparatus 200. In this manner, heavier items, such as a fluid-filled syringe,
scalpel,
or other instrument can rest on the table to prevent inadvertent breakage or
damage
to the medical instrument which is inserted into side surface cushion layer
228.
In the depicted embodiment, the movable bottom member 215 is partially
closed in relation to the other components of housing 201. As previously
discussed, movable bottom member 215 may be secured to housing 201 utilizing a
hinge 217. Snap fit flange 222 on the outer periphery on a portion of movable
bottom member 215 may allow for securement of the movable bottom member 21.5
to snap fit ridge 220 of housing 201 (see Figure IOA and 10B). In this manner,
when movable bottom member 215 is closed, the fit between snap fit ridge 220
aind
snap fit flange 222 may effectively secure movable bottom member 215 to the
other components of the housing, thereby securing the position of top surface
cushion layer 226 and side surface cushion layer.228.. A bottom margin support
member 218 is also shown. The illustrated bottom margin support 218 may be
configured to contact side surface cushion layer 228 to ensure a desired fit
between
side surface cushion layer, top barrier surface 214, and movable bottom member
215.
Figure 1lB illustrates sharps holder apparatu.s 200 during use. In the
illustrated embodiment, the movable bottom member 215 may be -secured to the
other components of housing 201. In this manner, top surface cushion layer 226
and side surface cushion layer 228 may be secured within housing 201 to allow
for
desired operation of the sharps holder apparatus.
A needle syringe combination 242 is depicted as being inserted irito side
si,urface cushion layer 228. The needle syringe cornbination may include an
amount
of fluid which adds substantially to the weight of needle syringe combination
242.
In the event that needlc syringe coinbination 242 were inserted into top
surface
cushion layer 226, the weight of needle syringe combination 242 could tip the
sharps holder apparatus 200 or inadvertently result in breakage *of the needle
portion of the needle syringe combination 242. In the illustrated embodiment,
needle syringe combination 242 can rest on the surgical surfaoe on which the
CA 02626077 2008-04-17
WO 2007/065110 PCT/US2006/061355

needle holder apparatus is positioned. In this manner, positioning of the
needle
syringe combination 242 is maintained until the needle syringe conibination
needs
to be utilized again or until the entire needle holder apparatus, including
the needle
syringe combination 242, is disposed.
As illustrated, needle tips 244a and 244b may be positioned within the top
surface cushion layer 226. In the illustrated embodiment, a first needle tip
244a
may be positioned within a first target 233 and a second needle tip 244b also
positioned within a different target 233. In this manner, the practitioner can
quickly idcntify potential open areas where needle tip or other sharp
implement can
be inserted. Additionally, the practitioner can quickly identify the amount of
remaining space for sharps that are used -in connection with subsequent
portions of
the procedure.
The top barrier surface 214 may be provided to prevent inadvertent insertion
of a needle or other sharp implement into the top surface 236 (not shown) of
side
surface cushion layer 228. In this maiiner, inadvertent migration of a needle
tip
through top surface 236 of side surface cushion layer 228 and out througli
side
surface aperture 210 may be prevented.
