PERISTALTIC PUMP ASSEMBLY AND REGULATOR THEREFOR
First Claim
1. A peristaltic pump assembly, comprising:
- a pump body;
a cassette removably attached to the pump body, wherein the cassette includes a race configured to provide a compression surface for a tube supported by the cassette;
a roller assembly operatively connected to the pump body, wherein the roller assembly includes a plurality of rollers configured to apply a predetermined force to the tube, thereby compressing the tube against the race; and
a regulator disposed in the pump body and operatively connected to the cassette, wherein the regulator is configured to regulate the predetermined force applied to the tube.
