一种利用普通心电图机的监护功能的扩充

Extension of Cardiac Monitoring Function by Used of Ordinary ECG Machine

以研究适合我国国情、利用现有的常规心电图仪设计出一种低功耗的便携式液晶显示心电监视仪 ,除了对其总体方案进行了论证外 ,还完成了硬件和软件的设计。系统采用 80 c196单片微型计算机为中央处理器 ,对实时心电信号进行数据处理和分析。该机除了具有一般的监护性能外 ,同时还具有五种心律失常分析、报警 ,以及冻结、自动走纸记录功能 ,能交、直供电 ,携带方便。本文力求简化硬件电路 ,优化软件结构 ,采用并实现了多种低功耗设计方法以及液晶显示模块化设计。所实现的监护仪通用性强、成本低 。

This paper deals with a portable monitor system on liquid crystal display (LCD) based on this available ordinary ECG machine, which is low power and suitable for China's specific condition. Apart from developing the overall scheme of the system, this paper also has completed the design of the hardware and the software. The 80c196 single chip microcomputer is taken as the central microprocessor and real time electrocardiac single is data treated and analyzed in the system. With the performance of ordinary monitor, this machine also possesses the following functions: five types of arrhythmia analysis, alarm, freeze, and record of automatic papering, convenient in carrying, with alternate current (AC) or direct current (DC) powered. The hardware circuit is simplified and the software structure is optimized in this paper. Multiple low power designs and LCD unit design are adopted and completed in it. Popular in usage, low in cost price, the portable monitor system will have a valuable influence on China's monitor system field
