Abstract

1287836 Rotary pumps RHONE-POULENC S A 26 Oct 1970 [27 Oct 1969 10 Sept 1970] 50819/70 Heading F1F A peristaltic pump 10 used for pumping blood from the vein of an arm 11 of a patient to a dialyzer 12 and back to the vein, comprises a flexible silicon elastomeric tube a pumping portion 14 of which is lightly stretched i.e. tensioned over an array of barrel or double truncated shaped rollers 16 and secured by a pair of adjustable clamps 19, 20 to a support 18, whereby the pumping portion 14 is periodically and sequentially constricted by the rollers 16 rotating as a set about a central axis 17 to effect a peristaltic action, the tube of at least the pumping portion 14 having such a wall thickness and being of such flexibility that collapse of the walls of the pumping portion 14 will occur, Fig. 3 (not shown) when a predetermined pressure differential exists between the interior and exterior of the pumping portion 14 to restrict the flow therethrough and thus automatically regulate the pump output, whereby if the supply of the vein drops below the flow-rate of the pump the vein is prevented from being emptied of its blood and subsequent collapse.
