多通道动态心电图机检定的测试架

Development of verification test stand for multichannel Holter

介绍了一种用于辅助检定动态心电图机的测试架。该测试架采用在电木板上加装多路接线柱的设计,经信号连接层使检定装置输出的一路信号转换成多路信号,实现对多台动态心电图机的输入。实验验证,此测试架可辅助用于多台动态心电图机的同时检定、校准、测试工作,节约了时间,提高了工作效率。

This paper introduces a kind of test stand for auxiliary verification of Holter. The test rack is designed by adding multi-channel terminals on the bakelite board. Through the signal connection layer, the output signal of the verification device is converted into multi-channel signals, and the input to multiple dynamic electrocardiographs is realized.Experimental results show that the test stand can be used for simultaneous verification, calibration and testing of multiple Holter machines, saving time and improving work efficiency.
