SUPPORTING CUFF FOR TRANSFUSIONS OR PERFUSIONS
Abstract
Supporting cuff for transfusions or perfusions held in place on
the patient's limb and supporting a removable block comprising
three nozzles positioned at 90.degree. to one another in the same
plane and controlled by a three-way cock, the nozzles corresponding
respectively to two female inlets which receive the liquid from the
bottles and one male outlet for distributing the liquid, the male
receiving the mouthpiece of a catheter tube or of an intravenous
nylon tube, the three-way cock permitting either to stop the
injection or to distribute in successions the liquids from one of
the bottles. The catheter tube or the intravenous nylon tube
includes a loop or slack enabling the patient to move his limb.

Claims
I claim:
1. A fluid connecting device for use with transfusion operations,
comprising a base structure having top and bottom surfaces adapted
to be secured to a patient's limb and a valve member removably
fitted on the top surface of said base structure, said valve member
having at least one inlet port adapted to be connected to a tube
originating from a bottle containing a transfusion fluid and one
outlet port being adapted to be connected to a catheter means to be
lodged in a patient's limb, and said base structure being provided
with at least two spaced apart spacing members projecting from the
bottom of said base structure and adapted to engage the patient's
limb.
2. A device as claimed in claim 1, in which said base structure is
made of resilient material and has recesses extending therethrough,
said valve member having knob means adapted to be fitted by
pressure in said recesses.
3. A fluid connecting device according to claim 1 and including
means for securing the base structure to a patient's limb and
wherein the valve member includes two inlet ports, each adapted to
be connected to a tube originating from a bottle containing a
transfusion fluid and one outlet port being adapted to be connected
to a catheter means to be lodged in a patient's limb and a
three-way cock member adapted to connect the outlet port
alternatively to either of said inlet ports.
4. A device as claimed in claim 3, in which said valve member is
connected to said catheter means.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a supporting cuff for transfusions
or perfusions.
It is known that the procedure for intravenous transfusions or
perfusions comprises introducing a needle or catheter in a vein.
The needle is ordinarilly connected to a blood or biological serum
bottle which distributes the liquid dropwise by gravity. The needle
or the catheter are held in situ by means of a piece of a
sticking-plaster or adhesive material, such as, tape or the
like.
It is also known that the patient, as a result of pain, fever or
ankylosis of the arm, for instance, is likely to stir and to
thereby shift the end of the needle located in the vein, sometimes
bringing on ejection of the needle and even hemorrhages. A recent
transfusion technique provides passing a small nylon tube inside
the needle, the tube then being pushed inside the vein permitting
withdrawal of the needle.
In both cases the withdrawal of the needle or of the nylon tube, as
a result of movements of the patient, are serious disadvantages
which can only be prevented by a constant watch. These devices,
moreover, only permit injecting the liquid from a single supply
bottle.
SUMMARY OF THE INVENTION
The object of the invention is, therefore, to provide a fluid
connecting device for use with transfusion operations, comprising a
base structure adapted to be secured to a patient's limb and a
valve member removably fitted on said base structure and having at
least one inlet port adapted to be connected to a tube originating
from a bottle containing a transfusion fluid and one outlet port
being adapted to be connected to a catheter means to be lodged in a
patient's limb, and said base structure being provided with spacing
members projecting from said base structure towards the patient's
limb.
It is another object of the invention to provide a fluid connecting
device in which said base structure is made of resilient material
and has recesses extending therethrough, and wherein said valve
member having knob means adapted to be fitted by pressure in said
recesses .
Still another object of the invention is to provide a fluid
connecting device, and said valve member comprising two inlet ports
and one outlet port, as well as a three-way cock member adapted to
connect such outlet port alternatively to either of said inlet
ports.
According to a preferred embodiment of the invention, said valve
member is connected by welding either with a tubing of said
catheter means or with an intravenous nylon tube.
Other details and features of the invention will stand out from the
following detailed description given and with reference to the
accompanying drawings, in which:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows an isometric projection of a patient's forearm on
which the cuff is fastened.
FIG. 2 shows an elevational sectional view of the base and of the
block thereof, illustrating the removable fastening of the said
block on the base.
FIG. 3 shows a plan view associated with FIG. 2.
FIG. 4 shows the respective positions of the three way cocks, of
two blocks coupled in I to connect up with the bottle 1, in II to
connect up with the bottle 2, and in III to connect up with the
bottle 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In accordance with the present invention there is provided a fluid
connecting device which includes a valve member or block 5 having a
cap 4 and a rotatable lever or handle M. Movement of the handle M,
as will subsequently be shown, dictates which of the bottles,
interconnected to the valve member, will be rendered operable. The
valve member 5 is removably seated on a base 7. A plurality of
studs or spacing members 8 rest on the patient's limb such that the
vein under consideration passes therebetween. Bandages 9 secure the
base 7 to the limb 9. The base 7 has formed in the bottom thereof
recesses recesses The recesses receive the knobs 11 of the block 5.
The knobs fit within the recesses solely by the application of
pressure and are removable therefrom, likewise, by pressure. A tube
12 originating from the bottles (not shown) connect to the valve
member 5 which in turn is connected to the catheter tube or nylon
tube 13 with a loop 14. A sticking plaster or adhesive tape hold
the catheter at the entry thereof in the arm 16. The valve member 5
includes female nozzles 17, 18 which receives the mouthpiece of the
tubes 12 from the bottles and a male nozzle 19 for connecting of
the valve member or block 5 to the catheter.
It will be noted that the base 7 firmly held on the arm 16 by the
bandages 9, receives the tube 12 connecting it to the bottle, not
shown, it being possible to mount the latter indifferently on
either of female nozzles 17 or 18. The block 5 being secured by
mere pressure, by means of its knobs 11, being blocked in the
housings 10 of the base 7 will easily permit positioning or
removing after each operation of the said relay-block 5.
In case it should be necessary to connect up a third bottle,
another block, not shown, may be easily fitted by means of its male
nozzle inside the female nozzle 18.
It will be readily appreciated that the invention has only been
described and illustrated in a purely explanatory and
non-limitative way and that some details thereof may be modified
without changing the scope thereof. Thus for instance it is
possible to omit the valve device by providing inside the female
nozzles, a ball biased by a compression coil spring resting on a
valve, the ball being released by the pressure of the end of the
male mouth pieces originating from the bottles, suitably fitted to
push back the ball and free it from its valve.
It is well understood that the invention is not limited to the
described embodiment and that many changes may be introduced
therein without departing from the scope of the present patent
application.
