Abstract:
Objective:In order to detect blood oxygen saturation timely,accurately,and conveniently,a wireless blood oxygen saturation detection module has been developed.Methods:Based on wearable monitoring technology and ZigBee wireless communication technology,we designed a blood oxygen saturation module of finger cuff type.This system is composed of photoplethysmography detection micromodule,ZigBee access terminal,and data analysis program,which realize the functions of waveform display,SpO2 calculation,wireless date transmission and so on.Results:The results show that detection accuracy of photoplethysmography is 98%,and calculating error of SpO2 is less than 8.8% satisfying the performance index of blood oxygen saturation detection.Furthermore,ZigBee wireless communication technology and light source regulator can reduce energy expenditure effectively.Conclusion:With the characters of wireless,low power consumption,miniaturization,and high performance,it can truly reflect physiological condition of patients,and remove lines on them,which make it possible for mobile monitor.
