The development Telemedicine system for blood pressure monitoring via Ethernet

The objective of this study was to develop an Ethernet-based telemedical blood pressure monitor. Although telemedical applications utilizing a variety of media are currently available, present systems do not provide remote signals with regard to integrated vital information, including blood pressure and pulse rate. In addition, the existing systems are largely embedded-structure, single-access, single-process models. Thus, we developed an Ethernet-based blood pressure monitor which includes a client/server structure, and is a real-time multi-access and multi-process system. The client for the developed system uses the Microsoft Comm Control in Microsoft Visual Basic and ODBC to connect Microsoft Chart Control with DB for a user interface. The server is programmed with the J2SE development platform, in a multi-thread structure. The system is capable of receiving data simultaneously. A TCP/IP socket was used for the Ethernet connection. The JDBC was applied to connect with the database for the saving, searching, and sampling of the data. The data transfer failure rate of the developed system was determined to be less than 0.05%.
