一种新型电生理信号现场采集装置——软盘数据采集系统

A novel instrument for on-site collection of physiological signals floppy DISC data acquisition system

本文介绍了一种软盘数据采集装置。它可用于现场采集四路微伏级的电生理信号,同时将其连续记录于5(1/4)吋软盘上。其存贮格式与IBM—PC机兼容,因而采写的数据可以很方便地在PC机上回放和分析。该装置是结合心室晚电位的采集而设计的。本文着重介绍装置的结构、原理以及各主要环节的实现方案。

In this article we introduce a novel data acquisition instrument which can be used for onsite collection of electrophysiological signals of μ v-level to be recorded directly on 5(1/4)' floppy DISC. Since the floppy DISC is formated to be compatible with IBM-PC,the data collected can be conveniently retrieved and analyzed with a PC.The instrument is designed for the field acquisition of ventricular late potential. Particular emphasis is laid on the structure of the instrument,the principle of operation,and the implementation of its main parts.
