家用心电图仪

Research and Design on Household ECG

针对当前医疗机构对心电监控设备的要求,文中介绍小型化家用心电图仪。从信号采集子系统,数字控制子系统和PC处理子系统三个模块入手介绍设备的设计组成,给出设计框图和器件的选型。还在虚拟仪器的概念上设计PC机终端软件,提供自动判读和网络传输功能。制作了实际的样机,用于进一步的安全设计。

In this paper a new minitype household ECG,based on investigated of hospital is introduced.the systern on three ele- ments:signal collection subsystem,digital controller subsystem and PC-end processor subsystem are described.the block diagrams of systen and the collection of devices is goven.The a software on PC based on the concept of virtual instrument are designs,which can analysis the ECG data automatic and transmit on the network.A prototype of household ECG was made based on the research, which used to check the system and safety design in future.
