Purpose: The Healthcare service using a wireless device contains a sensor device using measured biosignal data, the transmission of data, and a home health network. Methods of data input, transferring, and managing biosignal data vary greatly, so the transferred data format needs to be standardized to meet data transmission methods like Health Level 7 and IEEE 1451, etc. HL7 V3 Messages can apply to the scenario of biosignal data exchange. We designed a system managing biosignal data for patients in home.
Materials and Methods: The system is composed of 4 major parts: [1] the generation of HL7 messages based on standardized biosignal data [2] the generation of query interaction message templates [3] the design of biosignal information database [4] a client/server program based on personal biosignal information management.
Results: We implemented the client/server application using the method of HL7 Query Messages in the specific scenario about biosignal data management. Also, the HL7-based biosignal messaging template and the database were designed. In the user interface, patient/doctor’s options were developed separately and they enabled each user to have a sorted view of the accumulated data. The application using the standardization transmission protocol (HL7 V3 Messages) was XML format to input and search the data.
Conclusion: The standardized data transmission are so essential to share healthcare data and simplify software applications. Although their implementations were not easy to apply real situations, they would be a requirement in healthcare delivery systems.
