Abstract

1337407 Reciprocating Pumps R F SHAW 2 Dec 1970 [5 Dec 1969] 57308/70 Heading F1A [Also in Division A5] Liquid infusion apparatus for pumping liquid only from a variable volume pumping chamber 67, 69 which may also contain gas comprises an outlet valve 72 biased against outflow therethrough for fluid pressures in the chamber less than a certain value, means for decreasing the volume of the chamber during discharge periods by a fixed displacement volume 67 which is less than the residual volume 69 of the chamber after each discharge period, and an inlet communicating with the chamber and having means permitting fluid passage therethrough between discharge periods but preventing flow during such periods. Liquid from a supply 33 passes via a drip chamber 35 into a reservoir 63 in pump housing 61 and these into chamber 67,69 via ports 87 when a piston 73 is in an upper position. The piston 73 is moved against a spring 81 by a coil 83, periodically energized by a source 85 out on a magnetic plate 75, to pump liquid via valve 72 into a tube 31 connected to a catheter. The valve 72 may be manually disabled on moving a member 78 against a spring 76 so that gas may be bled from chamber 67, 69 prior to use of the apparatus. Said certain value of fluid presserve may be abouy 5 p. s.i.g. and the residual volume 69 may be at least about four times the displacement volume 67. Alternative embodiments utilize a peristaltic pump or a bellows-type pump, Figs. 5, 6, (not shown), respectively.
