摘　　要：运用自动控制理论,设计出由LDB—M型电子蠕动泵、Apple—Ⅱ微型计算机构成的负反馈闭环自动灌流系统。该系统能自动完成均匀斜坡升、阶梯升、阶梯升降等灌流压曲线。同时对实验动物的平均血压、平均灌流压及心率进行实时数据采集,最后作自动分析统计。A feedback closed-loop automatic perfusion system was developed by using an electronic peristaltic pump and an Apple-Ⅱ microcomputer. This system was able to provide three perfusion patterns: ramp, stepwise up and stepwise up-down. The blood pressure, heart rate and perfusion pressure might also be sampled and processed online.
