一种穿戴式心肺监测系统的设计及其试验研究

Design and experimental study of wearable cardiopulmonary monitoring system

目的:设计一种穿戴式心肺监测系统,并通过人体初步试验验证该系统的性能。方法:该系统由数据采集器、穿戴胸衣以及信息管理平台组成。其中,数据采集器以EFM32GG330单片机作为主控单元(microcontroller unit,MCU),其内部主要包括呼吸调制模块、心电调制模块、体位调制模块、无线通信模块(含蓝牙模块和Wi-Fi模块)、存储模块、电源管理模块等。穿戴胸衣采用开衫式结构设计,内侧设计有心电传感器和呼吸运动传感器。信息管理平台采用客户端/服务器(Client/Server,C/S)架构,通过Java/JavaScript实现软件编程。通过人体初步试验,将该系统与医院常规使用的迈瑞IPM10多参数监护仪进行对比,验证该系统监测人体心率及呼吸率的有效性。结果:该系统可长时间连续监测人体的心率和呼吸率,且监测结果与迈瑞IPM10多参数监护仪的监测结果具有很好的一致性。结论:该系统可用于训练或运动中的心肺指标医学监测,为健康管理提供精准的生理信息。

Objective To design a wearable cardiopulmonary monitoring system and validate its performance through preliminary human trials.Methods The wearable cardiopulmonary monitoring system was composed of a data collector,a wearing vest and an information management platform.The data collector used an EFM32GG330 SCM as the main microcon-troller unit(MCU),which included a respiratory modulation module,an ECG modulation module,a body position modulation module,a wireless communication module(involving in a Bluetooth module and a Wi-Fi module),a storage module and a power management module.The wearable vest had a cardigan-type structure,and was equipped with ECG sensors and respiratory motion sensors at its inner side.The information management platform was developed with Client/Server(C/S)architecture and Java/JavaScript.The system developed was compared with Mindray's IPM10 Patient Monitor routinely used in hospitals through preliminary human trials to verify its effectiveness in monitoring human heart rate and respiratory rate.Results The system developed could continuously monitor the human heart rate and respiratory rate for a long time,and the monitoring results had high consistency with those of Mindray's IPM10 Patient Monitor.Conclusion The system can be used for medical monitoring of cardiopulmonary indicators during training or exercise,providing accurate physiological information for health management.
