Implement ECG data transmission pathway combined of bluetooth low energy and TCP/IP protocol

Abstract

Health telematics, which helps to improve patient lives with high telecommunication technology and precise medical measurement, is a potential field in Vietnam healthcare system. In this project, a long-term ambulatory electrocardiogram (ECG) telemedicine system is proposed. The ECG signals are transmitted from a wireless ECG module to Android smartphone via Bluetooth Smart and from smartphone to Internet server via Transmission Control Protocol/Internet Protocol (TCP/IP) socket or Internet web-based protocol. Therefore, at first, an Android program is built in order to establish Bluetooth connection. Graphical function is also implemented for viewing purpose. After being received, ECG records are sent to Internet server by two methods. A SQL server is developed using PHP and JavaScript in order to process and store data. Finally, to retrieve data, client software is programmed using Microsoft Visual Studio, Android Studio and PHP designer. Experimental results show that the proposed systems provide high signal quality and stable real-time transmission. Some products in this work have joined the healthcare market.
