Design And Implementation Of A Wearable Reflection Pulse Oxygen Saturation Telemonitoring System

Oxygen is an important material of normal human metabolism,the blood oxygen saturation is one of the important parameters monitoring human blood oxygen content.Transmission type of noninvasive oxygen saturation monitoring equipment has developed more mature,and has been widely used in hospitals and community health care.Transmission type oxygen saturation monitoring equipment measuring location limitations at your fingertips and the earlobe,but cerebral blood oxygen,fetal blood oxygen cannot be monitored by transmission measurement.On the market in blood oxygen saturation monitoring equipment can only in local data measurement at present?Clinical blood oxygen measuring instrument is big and need to use a fixed power supply,so cannot be remote monitoring.With the improvement of science and technology level,to the human body parameters monitoring is proposed portable wearable,real time continuous and remote measurement of higher requirements,etc.In order to solve the above problems,this topic was designed and implemented the wearable reflection type pulse oxygen saturation monitoring equipment.Using reflection type sensor measuring pulse wave data,the method is not restricted by using the position and can care for a long time.Using ZigBee wireless transmission module for data transmission,which can realize remote blood oxygen monitoring.In order to meet the increasing requirements of human's day by day,to integrate the reflection type monitoring equipment to wear vest,implements the wearable reflex blood oxygen saturation monitoring system.In this paper,the main work content is as follows:1.The design of wearable reflection type pulse oxygen saturation monitoring system has been completed.2.The design of hardware of reflection type oxygen saturation monitoring equipment has been completed.Design of all module of the monitoring equipment,for example,Sensor driver module,filter module,display module and so on.Further study of the hardware anti-interference technology and make the PCB.3.Light emitting diode control logic,the signal acquisition process and the calculation of the values of blood oxygen were studied.A digital filter was designed to eliminate the interference signal in the process of signal acquisition.4.Remote monitoring system based on ZigBee wireless transmission network was designed and Remote wireless transmission of pulse wave signal was realized.Data analysis of pulse wave signal has been done by the software MATLAB.The relationship between SDPPG and tired has been researched.
