摘要
介绍一种新型、实用、低成本的胆管内压测试仪。该测试仪以MCS—51单片机为中心控制单元,实现多路数据的采集、处理、记录;并采用硬件修正方法对压力传递介质引起的信号变形进行了修正。该仪器还可用于其它生理压力的测量。
In this paper,a new type,practical and economical physiologic pressure measurement is introduced. In which,a single-chip microcomputer is used to control the collecting,processing and recording of multiplex data. And a rectifying circuit is used to rectify the deform of signal caused by pressure transfer in liquid.
