基于蓝牙技术的心电监护模块设计

ECG monitoring module based on Bluetooth technology

目的:针对我国远程医疗绝大部分局限在医院和医院之间的现状,探讨如何让远程医疗真正进入家庭,使患者足不出户即可享受到优质的医疗保健服务的问题。方法:设计了基于蓝牙技术的心电监护模块,心电监护终端由基于单片机系统的具有信号采集和简单处理功能的心电采集模块和蓝牙射频模块通过数据线相连构成;心电数据蓝牙传输模块的设计采用C8051F020和蓝牙模块ROK 101 007通过串口写入HCI指令来实现相互通信;采用VC++6.0作为开发工具编写运行于监护中心计算机上的远程监护服务器程序。结果:心电监护模块可实时采集心电数据并通过蓝牙模块接口传输到家用计算机,然后通过宽带网络系统发送到监护中心,从而实现患者和医生之间信息的实时交换。结论:该心电监护模块充分发挥蓝牙技术的无线优势,具有较强的实用性。

Objective To realize excellent remote medical treatment for patients.Methods The ECG monitoring module based on Bluetooth technology was designed.The ECG module and Bluetooth radio-frequency module,which possessed the function of data acquisition and simple processing,were connected through data wire to act as ECG terminal.By using C8051F020 and ROK 101 007 Bluetooth module,ECG Bluetooth transmission module read in HCI command through serial port,thus realizing mutual communication.VC＋＋6.0 was used as developing tool to edit remote monitoring server programme running on the computers in monitoring center.Results ECG monitoring module could acquire ECG data in real time and transmit it to personal computers,and then send it to the monitoring center through Wide Band.In this way,real-time information exchange between doctors and users was realized.Conclusion This module makes full use of the advantages of Bluetooth technology and has strong practicability.
