摘要
随着现代医学的快速发展,健康监护系统逐渐趋于成熟,可穿戴的监护系统越来越受欢迎;在此背景下提出了一种基于Android平台的便携式健康监测系统;利用光电探测电路获取光电容积脉搏波(photoplethysmography,PPG)信号,通过微处理器(MSP430)转换此信号为数字信号,然后使用蓝牙模块将数字信号发送至Android智能手机;在Android智能手机上开发应用软件,实现对PPG信号的波形显示、数据存储功能和生理参数的计算;为验证其可行性,分别对10名被测者进行了PPG信号的采集、传输、存储和心率的计算,将实验测得的心率数据与监护仪测量数据通过Bland-Altman差值法进行一致性检验,结果显示两种心率测量方法有很好的一致性;进一步的研究将在此基础上开发可监测更多参数的健康监护系统。
Because of the rapid medical development of our modern societies, the health care system becomes much more mature and pro- fessional. In this paper, a physiological parameter monitoring system is implemented with hardware circuit and Android platform. The physi- ological signal is firstly extracted from photoplethysmography （PPG） principle into electric signal. Then a microprocessor （MSP 430） is used to convert the electric signal to digital signal, suitably for sending to smart phone with the Android process system via a hluetooth module. The digital signal will be displayed, stored and calculated by an application program developed on the Android platform. To verify the feasi- bility, ten volunteer was recruited to measure their signal of PPG. Then the signal is transferred and stored in the smart phone with the An- droid platform. The heart rate is calculated by application program developed in the smart phone. The Bland - Altman method was used to compare the heart rate measurements from the Android phone and the physiological monitor, the results are agree with the experimental re sults. In the future, the mobile monitoring system for multi--physiological parameters will be developed.
