Abstract
A peristaltic pump and tube body system disclosed includes a pump housing, a pump rotor rotatably mounted in the housing, and a motor for driving the rotor. The housing has a pair of opposed side walls hinged and releasably latched to the housing whereby insertion and removal of a pump tube is facilitated. The rotor has two rollers disposed at 180 degrees to one another together with opposed rigid bearing surfaces inside the housing which squeeze the latch to produce a pumping action when the rotor is rotated in either direction.
