摘要：
abstract: infusion system with peristaltic pump and peristaltic pump, and related system method are provided. the peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. the first and second pinch-valve cams 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 is coupled to the cam shaft. the plunger-cam follower engages the plunger-cam. the tube receiver is configured to receive a tube. the spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along the radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thus 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. _____________________________________________________________ translation of the abstract patent summary: "system, method and apparatus for fluid infusion". it is a peristaltic pump and related method and system. the peristaltic pump includes a cam stem, first and second diaphragm valve cams, first and second diaphragm valve cam followers, a piston cam, a piston cam follower, a tube receiver, and a piston driven piston. spring. The first and second diaphragm valve cams are coupled to the cam stem. the first and second diaphragm valve cam followers engage the first and second diaphragm valve cams, respectively. the piston cam is coupled to the cam rod. the piston cam follower engages the piston cam. The tube receiver is configured to receive a tube. the spring-oriented piston is coupled to the piston cam follower such that expansion of the piston cam along a radial angle across the piston cam follower as the cam stem
