摘要：
A peristaltic pump (719), and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams (720, 726), first and second pinch-valve cam followers, a plunger cam (722), a plunger-cam follower, a tube receiver, and a spring-biased plunger (723, 724, 725). The first and second pinch-valve cams (720, 726) are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam (722) is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube (728). The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube (728). In other embodiments the plunger may be pivotally mounted to the pump housing.
