XJJ-4型心率监测仪具有心电图显示、心率计数、心率上下限设定、心率异常报警、自动记录、除颤等多项测试监护功能,被广泛应用在医疗临床诊断、教育和科研等单位,是一种较受用户欢迎的新型电子监测仪器,早期生产的监测仪采用9英寸显示器,只能显示一道心电图波形;后期生产的改进型同类仪器增设了部分控制电路,使其可同时监护四道以上的心电图波形,大大提高了工作效能。本文简述其工作原理及其检修,供参考。
XJJ-4 heart rate monitor with ECG display, heart rate count, heart rate limit set, heart rate anomaly alarm, automatic recording, defibrillation and many other testing and monitoring functions, is widely used in medical clinical diagnosis, education and scientific research units, Is a new type of electronic monitoring instrument that is more popular with users. The early monitor produced with a 9-inch display could only display an ECG waveform. In the later stage, an improved similar instrument was added with some control circuits to monitor four ECG waveform above, greatly improving work efficiency. This article briefly describes its working principle and its overhaul, for reference.
