摘　　要：基于PID控制算法的温控医用灌注泵,用于将常温下的生理盐水加热到37±1.5℃。输液管中的生理盐水在蠕动泵的作用下流进蛇型水袋,并在加热板的作用下迅速升温。该文对原有的温控医用灌注泵提出改进,增加一些相关的报警措施,包括:生理盐水温度或过低报警、加热板温度过高报警、水袋缺水报警和生理盐水出口水压过大报警,以提高设备的安全性,防止对术中患者造成进一步伤害,并防止设备的损坏。The temperature controlled medical infusion pump based on the PID control algorithm has been used to heat physiological saline from room temperature to 37 ± 1. 5 ℃. While physiological saline in the infusion tube flows into a snake- like bag through a peristaltic pump,it is rapidly heated through a heating panel. In this paper,an improved temperature control system for the medical infusion pump is described. In this system,some related alarm actions were added,including alarm on too cold or too hot temperature of the output physiological saline,alarm on too high temperature on the heater,alarm on water shortage,and alarm on too high pressure of the output physiological saline,so as to improve the safety of the device,keep the surgery patient from further hurt and prevent the equipment from damage.
