F. T. HQRIUCHI BLOOD TRANSFUSION APPARATUS Filed Nov. 5, 1935 "w ENTOR ATTORNEY WITNESSES Patented Mar. 16, 1937 UNlTED STATES PATENT OFFICE I 5 Claims.
This invention relates to surgical or laboratory apparatus and more particularly to apparatus of this character used during blood transfusion op-' Ierations.
' One of the objects of myinvention is to provide an j apparatus transfusion operations in which a receiver vessel 7 is employed for the storage of the blood between stages of the operation, the receiver vessel being provided with novel means for inducing a readily controllable yacuum within the vessel whereby to vacuum within the vessel, the same meansbeing I pin a vessel, which means,
ticity thus toe effect the drawing in or suction of the blood towithin the vessel. 1
I Another object of my invention is'to provide a receiver vesselincluding means for creating a adapted to generate a pressure within the vessel 'so as tocause the contents of same to be forced out of the vessel into suitable piping provided for the purpose. I
Briefly stated, my invention resides in the'provision of expansible and contractible means, such, for example as a rubber globular member withbeing subjected to a 'supplyof air under pressure, will be caused to expand or inflate in the vessel and thereby displace the air or other matter inthe vessel, and
inversely as the air within the bulb is discharged ,the-sam'e will contract or deflate of its own elas- 'iiect the induction'of'a-vacuum within the vessel;
One of the features the high sensitivity with which my device may function in drawing in the blood or ejecting same was to 'facilitatethe control of the vacuum or pressure within the vessel to an exact degree, thereby rendering the device particularly adapted forthe purposes indicated." The invention will be 1y understood from a consideration of thefollowing detailed description when read in connection with the accompanying drawing which forms ,part of the application,.with 'the understanding,. however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing :nor to the precise construction described and, therefore, such changes and modifications may be made therein .as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims. I
r In the drawing: Fig.-'-' 1 is a front elevational view of my apparatus partlybroken away in central section. Fig. 2'is a; side .elevational view of same. Fig;*3 is'a transverse sectional view taken on line 3+3 of-Fig. 1.
Fig. '4 is an enlarged central vertical section of the vessel stopper shown in-Fig. 1, showing my novel check valve arrangement; and
particularly adapted for blood of my invention resides, in
fully and comprehensive- Fig. 5 is a transverse sectional view of the inflator bulb taken on line Cy-5 of Fig. 2.
Reference is now had to the accompanying drawing for a more detailed description thereof, in which the numeral 6 indicates the receiver vessel of my blood transfusion apparatus con- I structed of transparent material, preferably cylindrical in shape, and having hemispherical ends. The vessel 6 is suitably calibrated, as indicated at I, to indicate the contents of same.
Within the vessel 6' is disposed a closed resilient tube 8 preferably formed of a high elastic rubber, shaped and'proporti'oned in conformity with the interior of the vessel 3. The tube 8 in normal uninflated condition, as shown in full lines in Fig. l, is of a minimum size appreciably smaller than the interior of the vessel 6 but amply elastic so that upon inflation of the tube 8 same will assume the size and'approximate proportion of the vessel 6.
In order to fix the minimum size of the tube 8 so that the same may not contract beyond a certain limit during its deflation a reticular structure or suitable framework 8a is provided. In its preferred form the structure 8a embodies a tubular form of woven wire material in conformity to the interior of the tube 8 when the latter is slightly'inflated. The member 8a is held in vertical position by having its lower end attached to the nipple l3. The provision of the member 8a; will thus limit the contraction of the tube 8 during the deflation of the latter to a definite degree, so that the tube 8 will always have the same minimum displacement and therefore the vessel Ii will always have the same maximum capacity.
The lower end of the vessel 6 is constricted to form a neck 9 turned outwardly at its free end to form a flange I0. Into the neck 9 is suitably secured a flanged stopper II, in the center of which is formed an air inlet l2 which terminates at its inner end in a nipple l3 to which .the lower end of the tube 8 is securely attached. The stopper H is also provided with an inlet port l4 thru which blood or other liquid may pass to the interior of the vessel 6. The stopper II is also provided with an outlet port thru which the blood or other contents ofthe vessel 6 may be passed.
Theinlet port t4 and the outlet port l5 are each provided with a novel form of check valve l6 suitably arranged to check the flow of. the liquid in the opposite direction by closing the port, see Fig. 4. Each of the check valves l6 comprises a slidable disc I1 guided for axial sliding, movement on a series of guide ro'ds IS, the ends of which are thru suitable apertures in the periphery of the disc H. The respective ports l4 and I5 are each extended axially into the corresponding check valve chamber to form a valve seat l9, against headed over, which rods passv which the valve disc may rest to close the port.
The vessel 6 of my apparatus is suitably supported on a base 20 preferably of hollow circular form, from which extends upwardly a hollow conical structure 2| terminating in a circular flange 22 adapted to snugly receive the lower hemispherical end of the vessel '6. The conical structure 2| surrounds the vessel 6 slightly more than half its periphery so as to provide an opening 23, see Fig. 3, at the front of the apparatus thru which the condition of the stopper II and the associated apparatus may be readily observed. The flange 22 is correspondingly interrupted at the front of the apparatus to form an opening thru which the neck 9 of the vessel 6 may be readily passed during the placement of the vessel 6 on the base 20; To assure rigid support for the vessel 6 a bracket 24 is provided, which bracket is supported on a. suitable lug extending from the structure 2| and comprises a pair of semi-circular spring clips 25 adapted to surround and securely grip the neck 9.
From each of the ports l4 and 5 of the stopper extend suitable pipes 26, 26 which pass thru apertures in the conical structure 2| and are provided with valves 21.
vent valve 29 provided with a vent nozzle 30. The valve 29 is adapted to open or close the pipe line.28 and further to be set so that the pipe line 28 may be closed and vented into the nozzle 30. The pipe 28 proceeds outwardly beyond the vent valve 29, to the end of which pipe is connected suitable air supply means such as the bulb 3|. The bulb 3| is provided with an inlet 32 equipped with a check valve 33, the outlet of the bulb 3| also to be equipped with a check valve 34 so that upon contraction of the bulb 3| the air in same will be forced into the pipe 28 and upon subsequent expansion of same air will be drawn into the inlet 32, the check valves 33 and 34 operating accordingly.
To assure the rapid and complete expansion of.
the bulb 32 I have provided a novel spring means illustrated in detail in Fig. 5. The mentioned spring means comprises a pair of arcuate springs 35, each of which is bent at its middle to a V form 36 to presenta more resilient structure at this portion. springs 35 are slidably disposed interiorly of a pair of guide tubes 31, which tubes are diametrically opposed and secured to the girth of the bulb 3|.
During contraction of the bulb 3| the pressure of the hand is brought to bear on both of the tubes 31 against the force of the springs 35, which springs are thereby caused to flex at their centers 36 while the ends of the springs are caused to slide further into the guide tubes 31 to permit the easy contraction of the bulb 3|. Upon release of the latter the springs 35 are permitted to expand to their normal position, thereby urging the guide tubes 31 outwardly, thus to assist the expansionof the bulb 3| to its normal form.
Preparatory to employing my apparatus during a blood transfusion operation the bulb 8 is completely inflated within the vessel 6, thereby displacing the entire air contents within same thru the outlet port IS. The tube 8 is inflated by To the air inlet i2 is a connected an air pipe .28 into which is fltted a- The respective free .ends of the neck, an elastic thru connected into said elastic vessel 6 the tube 8 is inflated the desired amount so as to create the required pressure within the vessel 6, thereby forcing the blood contents thru the outlet l5 and its associated pipe 26'.
In cases where the blood is to remain in the vessel 6 an appreciable length of time it is desirable to employ a cooling agent, such as ice water. In such instances the bulb 8 instead of being inflated by air is inflated by the injection of the cooling liquid, which may be introduced by immersing the inlet 32 of the bulb 3| in the liquid, which liquid may be readily decanted thru the vent nozzle 30.
What is claimed as new is:
1. Blood transfusion apparatus comprising a substantially rigid vessel adapted to receive and hold blood and having an opening, a memberwithin said vessel adapted to be inflated and deflated, an inlet and an outlet tube connected into said vessel, a tube connected into said member, a bulb forinflating said member, a pair of guides oppositely connected onto said bulb, and a pair of opposed springs, the ends of which are slidably retained in said guide.
