Abstract
1312251 Reciprocating pumps NATIONAL RESEARCH DEVELOPMENT CORP 10 June 1970 [13 June 1969] 30168/ 69 Heading F1A A blood pump comprises flexible bags 1 and 2 in rigid containers 3 and 4, the bags being connected to a common inlet 8 and outlet 11 via ball valves 9, 10, 12 and the containers being alternately connected to source of suction and pressure, gas or liquid, to alternately distend and collapse the bags to draw in the discharge the blood. Containers 3 and 4 are suspended from spring- loaded pillars 13 and 14 controlling microswitches 17-20, so that the change in weight of the bags when full and empty operates the switches to change over the suction and pressure connections to the containers, Figs.2 and 3 (not shown).
