便携式心阻抗血流动力监测系统研究

Research on System of Impedance Cardiography Based Hemodynamic Diagnosing and Monitoring

研究一种便携式的心阻抗血流动力监测系统,用以监测病人的血流动力参数。设计中考虑了ICG信号的采集、传输问题,开发了基于USB接口的便携式ICG采集系统,同时利用Visual C++开发了相应的软件系统,两者配合,便可构成高性/价比的便携式血流动力监测系统。

This paper is to research into a kind of portable ICG monitoring and diagnosing system, which is used to monitor patient＇s hemodynamic parameters. Key techniques of ICG signals collecting, transmitting were considered, and a portable data acquisition system with USB interface was designed. Furthermore, a relevant software system using Visual C＋＋ was designed, which mating with the data acquisition system, an ICG-based medical monitoring and diagnosing system will come true .
