摘要
当前心电监护仪面临小型化,智能化和网络化的趋势,而目前普遍采用的遥测心电监护系统存在集中监护路数少,距离有限的缺点;远程心电监护系统具有传输速度不够快,费用高的缺点;且这两种系统都不能进行现场实时监护。作者研制的基于Linux的嵌入式心电监护仪,成功解决了这些问题。该监护仪采用嵌入式系统技术,不仅能对病人现场实时监护,而且能进行数据分析计算,具有成本低,体积小,重量轻,功耗低,性能稳定,网络功能强大等优点;通过因特网通信,它还能上传数据到监护中心以实现远程监护,具有速度快、成本低、可扩展性好的优点。该监护仪为医疗仪器的构建和网络化提供了新的解决方案,具有一定的应用价值。
Presently, ECG monitor encounters the trend of miniaturizing, intelligentizing and networking. Short distance and limited channels are shortcomings of the existed telemetric ECG (Electrocardiograph) monitoring system, while the existed remote monitoring system has the disadvantages of high cost and low Data Transfer Rate. Furthermore, neither of these two systems can implement real-time monitoring on the spot. So, an embedded ECG Monitor based on Linux, which successfully solves these problems, is introduced. With embedded system technique, this embedded monitor, which can not only realize real-time monitoring on the spot, but also analyse the ECG data, has the advantages of low cost, small volume, light weight, low power, high stability, powerful networking function and so on. And by communicating through Internet, which has the features of low cost, high data transfer rate and good expandability, it can also send ECG data to monitoring center in order to achieve long-term monitoring. The development of this monitor provides a new solution for medical instruments' implementation and networking, and is of certain reference value.
