Abstract
A peristaltic pump includes a frame, a tube, and a rotor, the tube being fitted in the frame. The rotor includes a rotary member and a roller, wherein the rotary member is rotatable relative to the frame, and the roller is movable along the tube for squeezing the tube to pump fluid in the tube, when the rotary member is rotated. The roller is connected to the rotary member in such a manner as to allow the roller to move between a first position that squeezes the tube and a second position that releases, i.e. does not squeeze, the tube, thereby avoiding permanent plastic deformation of the tube.
Claims21
