. l'orrning` a part ofjthe elastic -vesselorfv bulb f 9; is an elastic tube 23 which leads ton thefsource f of'fluid supply, while at the opposite end of .the-i vessel9, isan velastic tube-24 that formsa part duringeach rotation oif thefshaft 14 andy crankarm 15..-

ing through the device during transfusion, has no contact with the valves, thereby insuring against coagulation of the blood or fluid, during transfusion.

It will also be seen that the device ismechanically'closed to the infiltration of air into the blood stream, and the blood stream has a nonreversing flow. Each of these valves includes a rod 25 that extends through an opening in the base 5, the upper end 264 of each rod being extended at right angles to overlie. a-'por-A tion of the tube, with which the valve is used.

A collar 27 is secured to eachrod 25,`adjacent to the lower end thereof, which collarprovides..v

a support for the lower end of the coiled spring 28,'-associa`ted therewith,'the upper end of the coiled spring engaging the `lower end of the bearing 29, through which the rod25 extends.

Thus it will be seen 'that due to this construction, these valves arenormally urged to their active positions, by means of the coiled springs 28.

As clearly shown by Figure 4 of the drawings,

the lower end of the rod 25 of one valve, is en-v gaged by the lever 11, while the lower'end of the r'od25 of the opposite valve, is engaged by the lever 12. y

The inner ends of the'levers 11 and 12 are disposed in spaced relation with each other, andaregfso Aarranged that they will be engaged by the cams 29' and 30 respectively, which cams are Asecured to the shaft 14. 'I'hese cams 29 and 30 are so'arranged that when -one cam is movingtoelevate' a valve, the other cam is moving away from the valve lever associated therewith, allowing the valve'to move to compress the tube, cutting off the flow of liquid through the tube and elastic vessel or bulb 9.

l elastic vessel or bulb 9 is known, the quantity The free end'of the right angled portion 26 of each valve, is bifurcated to accommodate the latch 31 which swings upwardly to a position as shown by Figure 4, preventing the tube supported thereunder, from moving laterally to an inoperative position. y

Afc'oiled spring indicated by the reference character 32 acts to normally hold the latch member 31 against accidental displacement.

Connected with the tube 24, is a transparent tube 33, which'embodies a lateral extension 34.

to which the tube-35 is connected, the tube 35 leading from asuitable source of supply of saline or otherfluid used during the transfusionoperation. Tube 36 leads to the patient, and

connectswith one end of the tube 33, shown by g'ure 1. A

In the operation of the device, the tube 23 leading from the donor, is open, and the operator moves the crank arm 15 rotating the shaft 14'. As thejshaft 14 rotates, the plate 8 moves downf wardly compressing the elastic vesselor bulb 9. After the bulb hasbeen'compressed further rotation of the shaft will ycause the valve Aas'- sociatedy with the tube 23,'to open, allowing uid or blood to be drawn into the elastic vessel orl As the shaft isy further rotated, the valve associated with tube 23 will close, and the valve associated withtube 24 will open to the end that 'when-the plate 8 moves downwardly, the blood-or fluid drawn into the elastic vessel or bulb 9, will be forced through the tube 36, to the patient.

In view of the fact that the capacity of the of uid or blood used in the transfusion operation may be readily determined.

In the eventv that the elastic vessel or bulb 9 does not expand to its fullest extent the extension v21 will engage the' flange. 22,'restricting further movement of the'crank arm'15, until the elastic vessel or bulb 9 has fully expanded.

I have thus described the invention.
