反射式血氧饱和度测量系统设计
Design of Blood Oxygen Saturation Measure System Based on Reflection Type
摘要
Abstract
To improve the portability of the transmissive oxygen saturation measurement,a reflection type blood oxygen saturation test system is provided,including the sensor unit,signal separation and filtering unit,data acquisition and processing unit,and the display module.The sensing unit consists of a photoelectric sensor,which can transform the biological signal into electrical signal; the electrical signal is processed by the signal separation and filtering unit,which can extract the effective signal from the original signal; the processed signal is converted to digital signal after A/D converter,STC12C5A60S2,and the oxygen saturation value can be calculated through MCU (Micro Control Unit); the oxygen saturation result is displayed on the 1602 LCD (Liquid Crystal Display) screen.The experiment shows that the system can meet the clinical requirements with the measurements accuracy of ± 1％.关键词
