摘要：

目的為滿足生理監(jiān)測設(shè)備多功能、便攜式、網(wǎng)絡(luò)化的發(fā)展需求，本文將生理監(jiān)測技術(shù)和無線通信技術(shù)相結(jié)合，設(shè)計(jì)了一款便攜式的智能生理監(jiān)護(hù)儀，將多種生理參數(shù)的檢測通過藍(lán)牙傳輸?shù)绞謾C(jī)，使被監(jiān)測者行動不受拘束，實(shí)時、可移動地獲取和傳輸人體生理參數(shù)，滿足家庭監(jiān)護(hù)和遠(yuǎn)程醫(yī)療的需求。方法該監(jiān)測儀主要由MSP430f6638作為主控芯片，包括脈搏波采集電路與心電信號采集電路，單片機(jī)分時采集兩路信號，進(jìn)行中值濾波與均值濾波后將信號通過串口通信傳輸給藍(lán)牙模塊，通過藍(lán)牙模塊與手機(jī)自帶的藍(lán)牙進(jìn)行通信。結(jié)果該監(jiān)護(hù)儀包含少量外圍電路，只需連接3個心電極與1個血氧探頭，加之簡單的手機(jī)應(yīng)用操作。通過藍(lán)牙傳輸，可以通過手機(jī)實(shí)時顯示心率、血氧飽和度、血壓等生理參數(shù)。結(jié)論該生理監(jiān)護(hù)儀結(jié)構(gòu)簡單，經(jīng)濟(jì)實(shí)惠，操作方便，實(shí)時監(jiān)測，提供了一個便攜、高效、實(shí)時的家居化健康服務(wù)平臺。

Objective In order to conform to the multifunctional,portable and networked development requirments of the physiologic monitoring system,a smart physiological monitor was designed based on signal monitoring and wireless communication technology.Human physiological multiparameters were measured freely and in real time by mobile phone and bluetooth transmission,which satisfied the demands of family monitoring and remote medicine.Methods The main control chip of the monitor was MSP430f6638,including pulse wave acquisition circuit and the ECG signal acquisition circuit.Microcomputer respectively collected the two signals.After mid-value filtering and mean filtering,the signals were transferred to mobile platform by bluetooth module.Results The monitor was composed of a small number of peripheral circuits,three heart tips and a blood oxygen probe.With a simple interface operation on the phone,the multi-physiological parameters of heart rate,oxygen saturation and blood pressure were observed.Conclusions The smart physiological monitor is portable and economic,which provides a portable,high efficiency testing platform in real time for home health services.
