GUO Xing-ming1, DING Xiao-rong1, WANG Dong1, et al. Multi-parameter physiological signal detecting system based on USB Hub[J]. 2011, 30(4): 93-95. DOI: 10.13873/j.1000-97872011.04.012.
A multi-parameter physiologic signal detecting system based on the USB Hub is developed for the requirement of individualization physiological parameters examining function.Physiological signals such as PCG
ECG
etc
are collected as required through the sensors by the modularized physiological signal detection circuits
and connected to the USB Hub module with the funciton of electrical safety seperation for medical equipment via USB.The signals are transferred to PC from the USB Hub also by means of USB
and analyzed and displayed on the PC real time.This research has great significant meaning for the high reliability
easy service
flexibility and expansibility of the medical instruments.
