Abstract

A peristaltic pump system including an arcuate pressing surface, a force element that applies an occluding force towards the pressing surface, a drive mechanism that drives the force element, a diaphragm disposed between the pressing surface and the force element that defines a pump cavity, an actuator strip disposed between the diaphragm and the force element that receives the occluding force, deflects to deform the diaphragm, and occludes the pump cavity, a support structure that retains the actuator and diaphragm positions relative to the pressing surface, and a restitution mechanism that recovers the open pump cavity configuration.
