    1498398 Reciprocating pumps BAXTER TRAVENOL LABORATORIES Inc 21 Sept 1976 [27 Jan 1976] 38998/76 Heading F1A [Also in Division F2] In a hand-actuated, flexible-chamber pump for a system for infusing fluid, e.g. blood into the human body, a duck-bill valve 28, Fig. 4, in the pump inlet is deformable into its open position by rotation of a collar member 30 to vent air from the pumping chamber 22 and to permit free flow under gravity through the pump. The pump comprises a flexible tubular member 22 which is manually compressed and cleared to effect pumping and is connected to a fluid supply (11), Fig. 1, (not shown), via valve 28, tube 15, a filter (14) and a drip chamber (13), and to a delivery needle (19). Collar 30 has an out-of-round aperture 36a-d, Fig. 7, which conforms with the shape of the valve 28 in the "pump" position of the collar for operation of the valve as a check-valve, rotation of collar 30 to the "prime" position deforming valve 28 as shown into its open position. If pumping is attempted with collar 30 in its "prime" position, valve 28 still functions as a check-valve, and closes to prevent return flow to the supply.

    flattened hood 4 clap / nny element. The minimum size of the hole 6 is smaller, and the maximum is larger than the outer diameter of the outer tube 3 and the doubled thickness of the walls of the flexible housing 2. Valve light / is installed on the end of the flexible working chamber 7 of the volumetric hand pump connected by pipeline 5 through filter 9 and sump JO to the tank 11 Idkost and pipeline 12 - to the blood system of the patient.
    When the finger of the flexible working chamber 7 is deformed, its volume changes periodically and the transfused IB fluid is forcedly displaced by the circulatory system. Fluid enters the
    chamber 7 from tank J / through valve assembly /. In the working position, the sleeve 5 is rotated so that the non-circular
    The opening 6 is located at a large size along the flattened end 4 of the tube 3. At the same time, the coolant passes liquid B 7 and locks three pressures in chamber 7 during its deformation, i.e., it acts as a check valve.
    When the sleeve 5 rotates at an angle of 90 ° from | VERSTIE - & Most of them are OBOH.M in size located across the flattening end 4 of the tube 3, and the sleeve 5 deforms the end 4. Along the deformation of the tail 4 of the tube 3, a passage opens in the valve element. In this position, the liquid goes by gravity and opens a free passage for gases.
    which are removed from chamber 7, leveling system and circulatory system into reservoir II and further into the atmosphere.
    Thus, the proposed valve assembly allows realizing the mode of operation of the pump and the entire overflow system, at which the evolved gases are removed from H "X.
