Abstract

1487893 Peristaltic pumps ALPHAMEDICS Mfg CORP 12 June 1975 [19 June 1974] 25226/75 Heading F1U A peristaltic pump for use on intravenous units comprises a rotary wheel 8 carrying rollers 33 which squeeze a tube 6 against a pump shoe 9 and a plurality of pairs of radially extending, axially spaced pins 33 successively engage the walls of the squeezed tube to return it to its normal circular shape before being squeezed again by the next roller. As described three pairs of pins 36a, 36b, 36c are located between each pair of leading and trailing rollers 33a, 33b and the axial spacing between the pins of each pin pair reduces from pair 36a to pair 36c. The pumping shoe 10 is mounted on a support bracket 9 and is adjusted by a screw 12 to control the pump's delivery. The support bracket 10 slides on pins 17 and carries two latch arms 20 so that it can be moved away from the wheel 8 for insertion of the tube 6 which is gripped by end portions 14 of the bracket 10 and spring-biased clamping blocks 25.
