ABSTRACT:
A peristaltic pump includes pivotal reaction members having reaction surfaces formed thereon for cooperation with a rotor in effecting peristaltic pumping action. The pump includes an improved adjustable tube-gripping assembly for securing a fluid flow tube of any size within a predetermined range in a predetermined position relative to the pump with only a minimal decrease of interior cross-sectional area. The preferred tube-gripping assembly includes a fixed gripping member and a movable yoke, each having notches formed therein for receiving the tube. A latch system for maintaining the pivotal reaction members in closed position applies relatively evenly distributed closing force along the joint between the reaction surfaces.
