The present invention relates to means for ~
drawing and holding the flesh together along opposite ~`
sides of a skin separation such as on an incision, injury,
or laceration to hold the separated skin portions in the
most desirable condition for healing.
Many different kinds of bandage constructions
are known and are commonly used. One of the problems with
most known bandages and other dressings, however, is ~hat they
do not provide any means for drawing and holding together the
portions of the flesh adjacent opposite sides of a wound or
-~ open sore. Instead, most known bandage constructions
simply provide an adhesively attached protective covering;~
for the injury, and in some cases, they also provide a means
; for applying medication. So far as known, however, no
surgical dressing or bandage includes means for drawing the
flesh on either side of a wound or injury together so that
need for surgical stitching LS eliminated or reduced. This
is important when avoidance of sutural cicatrix is desirable
and is especially important in situations when injury occurs ~;
at remote locations where medical attention is unavailable
and when it is not possible, for a considerable period of
time, to bring the injured person to a doctor or other person
qualified to give medical assistance. In such cases, if some
immediate means, other than conventional bandaging, are not
used to dxaw the flesh together, there is a relatiYely yxeater
likelihood that functionally or cosmetically undesirable scar
tissue will form in the wound even if it is subse~uently
stitched, and furthermore, if treatment is substantially `~
delayed, it is often impracticable to stitch the untreated
wound and attendant scarring is substantially certain to follow.

The present constructions overcome these and other short-
comings and disadvantages of existing bandages, and provide
a construction which is simple to apply and will hold the -~
separated flesh portions of a wound together, thereby `;~
minimizing the chances for scarring. The present bandage
constructions can also be applied quickly and effe~tively by
persons having little or no medical training.
It is therefore a principal object of the present
invention to provide a multipartite bandage or dressing
construction with zipper or zipper-like means that are used
:: ,
to draw together the separate bandage portions and the flesh
thereunder, to improve the condition of the flesh during
healing and to reduce the possibility of the formation of
. ~ ' ' :
scar tissue.
Another object is to provide a bandage construction
.~ ~
which can be applied by persons having little or no medical
., :
skill and training and which is an effective means to minimize j--` ?
the need for surgical stitching.
Another objèct is to provide a relatively in-
expensive bandage construction which can be applied adhesively
: ,, :
as separate portions along opposite sides of a break in the
skin and includes means which can draw together the separate
~, bandage portions and the attached flesh thereunder.
Another object is to provide a relatively simple ~;~
, ::
bandage construction which can be packaged and sold for use
in hospitals, medical centers, and doctors~ offices and by
` ' the general public. ~;~
` Another ob~ect is to provide means to substantially
minimiz-e or eliminate the formation of scar tissue at locations
where the skin has been lacerated or broken open. ~;
~; Another object is to provide me~ns for more ~;~
accurately and uniformly drawing the skin together along
''' `. '
. . .
~ -2- ~ ~
',"`: ~, '.. - :,'.
105089~7
an open wound.
Another object is to minimize the surgical procedures
and the discomfort to patients in the treatment of ~kin
lacerations and other similar injuries.
Another object is ~to provide an emergency bandage
construction which can be used to close an open wound to
promote proper healing.
Another object is to provide betker means for
immediately closiny a wound involving a break in the skin
until medical help is available.
The construction in accordance with the present
invention includes a bandage for closing a wound comprising
first and second strip portions of a relatively 1exible
., . ~
material. Each of the strip portions has a skin attaching
surface and a flange formed of a flexible material extending
along one side edge thereof. A coating of an adhesive
substance is applied to at least a portion of the skin attach- ~ ;
: .
ing surfaces on each of the strip portions for attaching the
strip portions to the skin in spaced relationship to each
other and along opposite edges of the wound. At least a
portion of the adhesive substance on each of the strip portions
extends to the side edges of the respective surfaces thereof ;~
which are to be attached along opposite edges of the wound.
Cooperating engageable means including elongated male and
female members extend respectively along each of the flanges.
-:...................................................................... ; . . -.
The male member is movable into cooperative resilient engage-
~ ment with the female member when pressure is applied against ~ ~`
;~ the respective flanges in a direction to press the male and
, female members together thereby to unite and hold the strip -~
portions and the skin along opposite side edges of the wound
together.

Referring to the drawings more particularly by
reference numbers, number 20 refers generally to a bandage
constructed according to one embodiment of the present
invention. The bandage 20, sho~n in F~GURE 1, has two
separable portions including a portion 22 and a portion 24
The portions 22 and 24 are shown as bein~ similar in shape
and each is preferably formed of a plastic or plastic-like
material such as are commonly used in bandages. The two
portions 22 and 24 when combined in the structure 20 as shown ~ `
in FIGURE 1 have an overall size and shape similar to the ` ~
. .
size and shape of a more or less conventional bandage,
although both the size and shape can be varied as desired `~
and as is usual in the bandage art. Each of the portions 22 ;
and 24 has an adhesive coating 26 and 28 applied respectively
,:
on corresponding sur~aces thereof, namely, the bottom surface
as shown in FIGURES 1 and 2. The bottom surfaces may also
have a gauze or other similar plain or medicated absorbent
~I material positioned on the adhesive coatings 26 and 28, or the i
, ~ bandage may be constructed without any absorbent or medicated
'~ 20 material, which latter construction may in some cases be ~;
preferred. In addition to the features described above, the
bandage portion 22 has an attached or integral ridge or flange --
30 whiah extends along one side thereof. In like manner the
bandage portion 24 has an elongated ridge or flange portion 32
along one of the side edges. Referriny to FIGURES 2 and 3 it
can be seen that the flange portion 30 has one or more
sidewardly extending elongated beads 34 and 36, and the flange
portion 32 has elongated groove6 38 and 40 which are shaped to
cooperatively receive and engage the beads 34 and 36 ~hen the
..
beads are pressed into the respective grooves. Cooperating
~ ,
_5_
.
10~08~7
beads and grooves of this general type are well known and
widely used, and the flanges 30 and 32 are preferably formed
; of some plastic or plastic-like material having proper
resiliency and flexibility characteristics. Certain kinds
of plastic are particularly suitable for this type of
construction including some of the well known film or sheet
forming plastics such as polyethylene, polypropylene,
polyvinyl chloride, and the like. Natural ana synthetic ;
rubbers can also be used for this purpose.
la FIGURE 4 ~hows another embodiment 41 of the same
basic construction wherein the two bandage port~ons, identified
as portions 42 and 44, are connected integrally at one end
of the bandage 46. Over the rest of the length of the bandage,
however, the portions 42 and 44 are separate or separable,
each separable portion ~eing provided with a resilient and
flexible flange portion 48 and 50, respectively, each of which
;; is disposed at substantially a right angle to the correspondingseparable portion. The flange portions 48 and 50 m~y be
similar to the flange portions 30 and 32, and they may be ~
constructed to have one or more cooperating beads and grooves. ~ -
It is also contemplated to construct the bandage of FIGURE 4
~ with integral portions at both ends, if desired; in which
- case, only the inbetween portion~ will have cooperative flangemeans for attaching them together. Each of the portions 42
and 44 has an adhesive coating 43 and 45 applied, respectively,
~^` to the bottom surfaces thereof. The adhesive coatings 43 and
45 may also be provided ~ith protective overlayers of an
easily removable material 47 and~4-9, respectively, which may
be formed of wax or wax-like material or plastic. Such
~ 3a . layers of materials are also well known and commercially
: -
!

available and are removed just prior to the application
of the subject bandage to the skin.
FIGURE S illustrates application of the bandage
construction shown in FIGUR~ 4 to a wound such as to a
skin laceration or cut in the upper arm. The skin laceration
is identi~ied by the number 52. In FIGURE 5 -the bandage
portion 42 is adhesively attached to the skin along one side
:, ;
of the laceration 52 and the other portion 44 is adhesively
attached to the skin along the opposite side of the laceration,
lQ thus the wound i5 disposed between the portions 42 and 44.
It is normally also desirable to have the edges of the flanges
48 and 50 close to the edges of the laceration or, in some
cases, slightly spaced therefrom, but it is not usually
; desirable that the banda~e portions or the flanges overhang
j the wound itself so that when the flanges are brought together
for joinder they cooperate with the bandage portions to close
the wound. The positions of the bandage portions after being
., . . ~ .
attached are even more clearly shown in FIGURE 6 where it ~ `~
can be seen that the skin along one side of the laceration
, 20 is a &esi~ely attached to the bandage portion 42 and the
- edge of the wound is immediately adjacent attaching means
:, :
48, while the skin on the opposite side of the laceration
5~ correspondingly is a &esiYely attached to the bandage
portion 44 with the edge of the wound adiacent attaching means ~ -
:.` ' ' :, :
-,:! 50. The adhesi~e attachment of the bandage portions 42 and
44 is accomplished with the bandage portions separated from
each other hy the width of the wound therebet~een or by a
.. ' :,
i slightly greater distance. This is usually done after the ~-
flesh has been cleaned or treated adjacent to the skin
separation. Thereafter with the two bandage portions
;,: ` .
.,,

~05~ 7
adhesively attached in the positions shown in FIGURES 5 and
6, pressure is applied a}ong the members 48 and 50, usually
starting at one end thereof, ~o bring the cooperating
engagable means thereon together and into engagement. As
this is done, the bandaga draws the torn skin together, .
to be left in place until the healing process is completed. .
It is anticipated that in many cases it may be possible to
use the subject bandages to draw the skin close enough .
together so that it is not necessary to use any surgical
stitches, thus avoiding sutural cicatrix normally associated
therewith. In those cases where stitching is necessary,
the subject bandage may be used in combination therewith and ::
... .
~ as a substitute for the topmost layer thereof to avoid suture -:
; marks as above. The cooperating means are shown enlarged
for the sake of clarity, but they are preferably relatively `~.
small in cross-section and relatively close to the adhesively
:.
coated bandage ltself to maximize the pulling and holding
~ ~ force on the skin. ~ :
.. FIGURE 7 shows a modified embodiment wherein only
.. 1 20 one groove and cooperating bead are included in the cooperating
. '~!
attachment means. Selection of a particular embodiment ~:
depends on the desired holding power and the materials used ~. :
in the cooperating parts. In this construction, as above, ~;
the joining of the cooperating parts is accomplished without
pressure being applied downwardly into or against the wound.
FIGURE 8 shows the two-piece bandage 20 of the type
:~ shown in FIGURE 1 being applied to an open wound in the
upper arm. In this case, the two separate bandage portions `~
- 22 and 24 are separately applied by means of adhesive coatings .~ -~
; 30. 26 and 28, respectively, to the skin in the positions shown,
. ~
: , .
05089L7 ~ ! `
..',
adjacent the injured area and in spaced relationship to each
other. Once this is done, it is a simple matter to briny
the cooperative flange portions 30 and 32 i.nto engagement
along the length of the bandage. This is usually done
starting at one end of the bandage by pressing the flanges
together using the fingers or some other pressing means.
As the flanges are joined, the skin along the wound is brought
together to be held during the healing process. It is also
apparent that the present construction enables adjustment to
be made in the holding force applied in closing the wound by
properly positioning the separate bandage portions. This is
an important advantage since if the bandage is too tight for
comfort or too loose for effective non-scarring joinder of the
wound as initially applied, adjustment can be made either by
... .
relocating the separate bandage portions before rejoining
them or by replacing them with new bandage parts. This,
therefore, affords a relatively inexpensive way for achieving
the most desirable healing condition.
FIGURE 9 shows a somewhat modified embodiment of
2Q the aforesaid constructions wherein the bandage is provided
with gauze or other absorbent bandage pads 54 and 55 which are
attached in the usual manner to the adhesive side of the
bandage. The gau2e in this case extends only part way to the
side edges of bandage portions 22 and 24, respectively, as
` shown in FIGURE 9. It is also contemplated as mentioned above,
;~ to use a construction wherein there is no gauze or medicated
pad provided; in which case, the adhesive parts of the
~ bandage portions are applied directly to the skin adjacent the
I edge of the wound. This embodiment usually provides the
greatest and best holding power along the length of the wound,
. . .

but it may be desirable to perorate the separate bandage
portions at various locations, especially adjacent the
injury, to permit blood and other body fluids to escape.
In this type of construction, an absorbent gauze overlayer
or pad may be applied over the top of the attached bandage
portions to absorb the fluids escaping from the injury. The
overlayer or pad can be attached in any convenient way such
as by using adhesive tape or other attaching means.
FIGURE 10 sho~s another embodiment 60 of the subject
bandage construction wherein the bandage portions 62 and 64 have
respective ~longated s.ide edge flanges 66 and 68. The flange
66, in this case, has a plurality of sidewardly extending knobs
or beads 70 which are formed by narrow neck portions 72
and larger diameter head portions 74. The flange 68, on the
other hand, has a plurality o~ spaced holes 76 positioned to
cooperatively receive the knobs 70 when the two portions 66
and 68 are pressed together, see FIGURE 11. No gauze is ~`~
provided under the bandage portions 62 and 64, but they are
perforated as at 78 to facilitate the escape of body fluids
such as blood from the wound. The use and application of
construction 60 is similar to that described above for other ~-
constructions. The con~truction in FIGURE 10 is also shown --;
having an absorbent gauze o~erlayer 79 which is taped as by
adhesive tape 81 or otherwise attached to absorb any escaping
, I ~,, . :
~ ~lood or the like.
I FIGURE 12 shows another form 80 of the attaching
means formed on the separable bandage portions 82 and 84. In
: I , . ~
:~ this case the cooperating means are found on flange portions
86 and 88 which are in the plane of the bandage portions 82
and 84. The flange 86 in this construction has one or more
, " -10-

. ~
:.: : : .: ,
-.

elongated beads 90 which are shown extending upwardly there~rom
for engagement with complementary shaped elongated grooves 92
found in the flange 88. Application of the bandage 80 is
similar to that for the a~ove constructions except that in
this case the pressure applied to ~oin the bandage portions 82 .
and 84 is applied in a downward direction adjacent the damaged
flesh rather khan being applied in a direction normal thereto.
In the construction 80 the bandage portions 82 and 84 are
also shown having gauze pads 94 and 95 applied respectively to
: 10 a portion of their adhesive sides 83 and 85. The adhesive
sides as well as the gauze pads may also be overlayed with `~
~ another layer of a remov~ble and disposable material, such as
: are co.mmonly used on many bandages.
FIGU~E 13 shows embodiment lQ0 wherein the means or
atkaching the separable bandage portions together include
flanges 102 and 104 which have attaching means such as ~.
cooperating VELCRO means 106 and 108 applied thereto. VE~CRO ~:
i5 a trademark of John Dritz and Sons and is a type of attaching
, means wherein one member includes many little tines or hooks :
,: ~
: 20 and another member has a fabric or fabric-like material that
is gripped and held by the tines when they are b.rought into
engagement. In this case the bandage is applied as before
and after the portions are adhesively attached to the skin,
the flanges 102 and 104 are brought together so that their
cooperating means become entangled and interlocked thereby.
; FIGURE 14 shows another bandage 110 which has
flanges 112-and 114 attached to separable bandage portions
' 116 and 118, respectively. One or both of the ~lan~es 112
: and 114 has an adhesive 12~ applied to it, and the adhesive
is overlayed before use with a removable disposable strip or
.
,
.
- 10~4~
strips 122 and 124. The strips 122 and 124 can be made
as a sinyle folded member, one or both ends of which extend
beyond the ends of the respective flanges 112 and 114 to
facilitate removal therefrom. Similax non-adhesive members
126 and 128 can be applied to the other adhesive portions
of the bandage as shown. The members 126 and 128 have end
tabs or they can be lapped at the center of the bandage to
; permit ease of remo~al. In some cases only one of the flanges
112 and 114 need have an adhesive coating, although it is
normally preferable to have adhesive on both to increase
holding po~er.
FIGURE 15 shows yet another embodiment 130 which ;~
is similar to the above described constructions except that
in this case the flanges 132 and 134 are provided with a
moYahle zipper-type operator member or slide fastener 136
which can be easily moved in either direction along the
flanges to unite them or separate them in a manner common
to zippers. The engagable means found on flanges 132 and ~`
134 may be as described in FIGURES 1-14 or may consist of
2Q i~terlocking tabs in the manner of ordinary placket zippers.
It is also contemplated to combine various of
the bandage features disclosed herein as desired to achieve
a particular construction or desired result. Thus there
has been shown and described a novel bandage construction
which ful$ills all of the objects and advantages sought
therefor. Many changes, modifications, variations, and other
uses and applications of the present bandage construction
~ill, however, become apparent to those skilled in the art
after con~idering this application and the accompanyiny
dra~in~s; all such changea, modifications, variations, and
