基于微机控制的心脏电生理刺激仪的研制

THE DEVELOPMENT OF CARDIAC ELECTRICAL STIMULATOR CONTROLLED BY COMPUTER

本文介绍一种新的基于微机控制的心脏电生理刺激系统。利用微机可视化界面设置各项刺激参数,然后通过串行口将所有参数传送给外接单片机系统,最后由微机启动控制单片机按照既定模式发放刺激脉冲,同时微机接收单片机反馈的当前状态参数并将其实时显示在可视化界面之上。实践表明,该系统较以往的电生理刺激仪而言功能完备,操作简单,并且监测实时,在临床心脏电生理治疗中具有很大的应用价值。

This paper introduces a new Cardiac Electrical Physiological Stimulate System controlled by computer. Using the latter to make configuration of stimulation, and then transport all the parameters to the single-chip microcontroller system through the serial port, at last the microcontroller is started by the computer and begin to work under the configuration above, also the computer will receive the current status parameters from that single-chip system and display them on the visual interface. It has been proved to be more functional than traditonal systems, be easier to operate and also it has real-time monitor, so more valuable in medical application.
