INFUSION SUPPLY APPARATUS
BACKGROUND OF THE INVENTION
05 The invention relates to an infusion supply appara-
tus for the care of patients. The apparatus is designed for
mounting to a support and comprises a support plate and
supply connections. Such an infusion supply apparatus
is in particular used in operating rooms and intensive
care stations.
An infusion apparatus is provided in an operating
room as well as in an intensive care station at a respective
overhead or wall support. Infusion pumps, injection pumps
and infusion bottles together with the respective supply
connections which are passed into the support are provided
at an extension arm mounted to the support. Whenever a
patient is transported, for example, from the operating
room into an intensive care station the infusion bottles
and other parts which are indispensable for the infusion
during the transport of the patient are removed from the
support and hung to a kind of post. A11 associated pumps
are sepaxated from the voltage supply. Therea~ter the
bed and the post are transported whereby attention has
to be paid that the connection lines between the patient
and the means hanging down at the post are not impaired
by accidental movements of the post. In the intensive
care station the individual connection lines are again
connected and a conversion occures from the post ko a
support provided adjacent to t~e bed.
OBJECTS OF THE INVENTION
It is an objec~ o* the invention to provide an
improved in~usion supply apparatus. It is a further object
- 3 -
' ~ ~
)9~
of the invention to design an infusion supply apparatus
in such a manner that the infusion supply is rendered
safer and easier during the transport of a patient from
one station such as an operating room or intensive care
05 station to another such station. It is a still further
object of the invention to provide an infusion supply
apparatus in which the above mentioned drawbacks of the
prior art are avoided.
SUMMARY OF THE INVENTION
According to the invention an infusion supply
apparatus for the care of patients comprises a support
plate for an infusion means, said support plate having
supply connections and means providing a detachable connec-
tion with a stationary support on the one hand and a trans-
porting means on the other hand, said transporting means
including a coupling member for connection to a patient
transporting means.
It is the advantage of the inventive design that
the infusion members conn~cted to the patient can remain
unchanged and connected to the patient, the connections
lie above the be.d during the transport and therefore there
is no longer a danger of inadvertently braking the connec-
tions. At the end of the transport the support plate with the
supply connections is put onto a cantilever arm of a support
in a respective manner. Thereafter the transporting means
can be uncoupled from the patient transporting means and
removed.

DESCRIPTION OF PREFERRED EMBODIMENTS
An observational monitor 2 and an infusion means
3 are provided at the overhead support 1 shown in figure
1. The infusion means 3 comprises a storage tray or support
plate 4 which is laid upon a frame-shaped e~tension member
24 connected to the column of the overhead support 1.
The tray or plate 4 is locked against inadvertent movement
by means of a schematically indicated lock 5 to a counter-
piece mounted to the support and co-oparating with the
lock~ The necessary pumps 6 in the form o~ infusion pumps
and injection pumps together with a common connection
for the voltage supply are provided on the support plateO
Z~
- 5 -
The voltage supply is formed by a plug 8 which is provided
on the side facing the support and which is in a detachable
engagement with a co-operating plug of the support and
thereby provides the connection of the infusion means
05 with the supply lines passed through the support. Moreover,
a battery-operated voltage supply is provided on the support
plate for operating the individual devices on tha support
plate off-line for a predetermined period.
Fig. 2 shows a transporting means 9 comprising
a mobile chassis 10 with lockable wheels, a level-adjustable
support base 11 and a cantilever arm 12 mounted to the
top end of the support base. A fork-shaped portion 13
is provided at the free end of the cantilever arm 12.
As may be seen from figures 5 and 6 the associaked support
plate has a frame-shaped guide 25 at tha underside thereof
which is slightly smaller than the inner dimensions of
the fork-shaped portion 13. This guidîng device ser~es
as a guide against lateral displacement of the support
plate when resting on the fork-shaped portion. ,
The transporting means further comprises a coupling
member 14 for a positive connection with a peg-~haped
mounting 16 provided at a patient transporting means 15.
The coupling member comprises a recess 17 for
receiving the cylindrical peg-shaped mounting 16. The
recess is formed U-shaped in horizontal direction and
a cam or pin 18 projects laterally into the U-shaped recess
170 The cam is guided within a bore 19 having an access
which extends at an angle with respect to the axis of
symmetry of the U-shaped recess and towards the open end
of the U-shaped recess. A spring biases the cam or pin in
the position shown in figure 4 such that the pin projects
into the open end to such an extent that the peg-shaped
mounting 16 is prevented from slipping out of the U-shaped
,
-- 6 --
recess and a positive coupling is thereby obtained. The
rear end of the cam or pin is provided with a pull 20 for
pulling the pin to clear the U-shaped recess for releasing
the connection.
05 As best shown in figure 4 the portion with the
coupling member 14 is connected through a releasable clamped
joint 21 and the elavation thereof relative to the support
base 11 can be adjusted after loosening the clamped joint.
As further best shown in figure 4 a tray 22 for storing
access~ry containers is provided at the coupling member.
The tray is surrounded by standardized profiled rails for
mounting accessories at three sides thereof.
In operation th~ transporting means 9 is brought up
towards the support. The cantilever arm 12 is adjusted
by means of a level adjustment means 26 such that the
fork--shaped portion 13 grabs below the support plate 4
and receives the same. ~ter loosening the lock 5 the
transporting means together with the support plate received
thereby is directly connected with the patient transporting
means 15 which is positioned adjacent to the support without
the infusion means having to be removed from their base.
~fter connecting the transporting means ko the patient
transporting means both transporting means together are
moved along together with the patient. At the desired
new station the support plate 4 is connected with and
coupled to a support 1 provided thereat in an inverse
manner and thereafter the transporting means is removed
up to the time for the next application.
The transporting means comprises bu~fer members
27, 28 at the outer edges thereof in order to allow the
transporting means to ba easily directed in the coupled
state thereof. The buffer members contact the edge of the
patient transport means 15 such that a good connection is
obtained.
The ~igures 7 to 8b show further embodiments ~or
the mounting of the support plate 4 to the stationary
support 1 and to the transporting means 9-, respectively,
05 and the figures 7c and 9 show a further embodiment of
the coupling member between the transporting means 9 and
the patient transporting means 15.
According to figure 7a the stationary support
1 which may be an anaesthesia support for an operating
room or an overhead support for intensive care is provided
with a front-opened ~ork 13 which grabs below the support
plate 4 for the infusion means as represented in figure
7b.
The underside of the support plate 4 is provided with
two rails 27. The inner distance between the two rails
is slightly larger than the outer width o~ the fork 13
and the rails 27 grab around the fork.
A sectional top view of a locking mechanism 28
provided in both rails 27 is shown in ~igures 8a and b.
The locking mechanism 28 engages a groove 29 provided
in both forkes or fork arms 13 and thereby secures the
position of the support plate 4 at the stationary support
1.
The transporting means 9 shown in figure 7c compri-
ses a forwardly cranked or bent support base 11 with thecantilever arm 12 mounted thereto. The sidewalls 30 of the
cantilever arm 12 have a distance to extend around the
rails 27 of the support plate 4. Hence, if the transporting
means 9 is brought up to a position aside o~ the support
plate 4 and the extension arm 12 is brought up to the
respe~tive le~el by means of the level ad~ustment means
26, the cantilever a~m 12 may grab around the rails 27.
In the course o~ this the lateral walls 30 release the
Z~
-- 8 --
locking mechanism 28 from the groove 29 of the fork 13
such that the support platP 4 may be lifted from the fork
13 and detached from the stationary support 1, respectively.
When depositing the support plate 4 to the stationary
05 support 1 within the operating room, etc., the locking
mechanism again snaps into the respective grooves 29 after
the cantilever arm 12 has been removed from the rails 27.
A further (not represented) locking mechanism
can be provided for securing the support plate 4 on the
extension arm 12 .
Figure 7c also shows a further embodiment of a
coupling member between the transporting means 9 and the
patient transporting means 15. To this end two hooks 31
formed to extend below a portion of the patient transporting
means 15 are provided at the upward-movable part of the
support base 11. When the transporting means 9 is, ~or
example, rolled below the rear part of the patient's bed
and lifted by means o~` the level adjustment means, the
wheels of the chassis 10 of the transporting means -take
over the rolling function of the patient transporting
means 15. Figure 9 shows the transporting means 9 with
the patient transporting means 15 coupled thereto. In
this case the wheels of the transporting means 9 have
taken over the ~unction of wheels 33 of the patient's bed
15.
In the last mentioned embodiment the hooks 31
are upwar~ly opened and the bed 25 i5 lifted when rising
with the aid of the level adjustment means 26. However,
it is also possible to hook the transporting means 9 to
the patient tr2nsporting means 15 with respectively down-
wardly opened hooks and to lift the transporting means
9 itself by means of the level adjustment means 26. In
the latter case the wheels 33 o~ the bed 1~ take over
- .:
.
`- 2~81~
the rolling function during the transport.
In this manner a perfectly safe and compact connec-
tion between the transporting means and the patient transpor~
ting means 15 is obtained and both transporting means
05 can be pushed by a single person, for example, into an
operating room.
The infusion means on the support plate 4 is safely
connected with the patient and there is no danger of loosening
tubes or other connections.
~ Although the invention has been descrihed with
reference to a specific example embodiment it is to be under-
stood that it is intended to cover all modifications and
equivalents within the scope of the appended claims.
