ABSTRACT:
A peristaltic pump constructed of a relatively small number of components so that performance and reliability criteria can be satisfied in a relatively economical and compact pump. In a preferred embodiment, the occlusion bed pivots about a pair of hinge pins integrally molded with the occlusion bed which are received in lugs integrally molded with the base of the pump. The occlusion bed also preferably includes an integral resiliently-biased latch member which cooperates with a latch plate integrally molded in the base of the pump. The pump preferably includes a rotor in which each of the roller support pins is molded integrally with one of the end plates. To secure tubing in place on the pump, a pair of cantilevered leaf springs urge tubing into slots on tubing retainer plates disposed adjacent the rotor. The roller pins and rollers may be made of a low friction composite material which eliminates the need for bearings therebetween.
