Abstract

1526099 Reciprocating pumps D N ROSS E BODNAR and D B RAY 19 Nov 1976 [29 Nov 1975 8 Jan 1976] 49184/75 Heading F1A A blood pump for connecting to the heart comprises a flexible but non-compressible chamber 1 having an inlet 2 and an outlet 3 with either biological or prosthetic check-valves and a connection 4 through which an inflatable bag 9 is insertable into and removable from chamber 1 and connected to a pulsating air or liquid supply for alternately inflating and deflating the bag to effect pumping. Inlet 2 has a flange 5 for attachment to the heart, and outlet 3 has a connection 7 for attachment to an artery. The inlet and outlet valves are supported by mountings 6, 8.
