Design Of The Medical Information System Based On HL7

It is Health Information System (HIM), a branch of medical informatics, that improves the level of hospital service. Meanwhile,followed the rapid development of network, many new difficulties come out, too. The exchange of information, the store of data and other questions are required to resolve.This thesis dissertates the overall scheme, technical route and module design of the HIS. The analysis to the HL7 has been carrying to meet the HL7 message parser and build. This standard as an international standard of the exchange of medical information is widely used and validated in the world. And the exception is given for the using of XML in HL7. In the following chapters (three layers of the system, the Web user interface, the database and the server) are dissertated respectively.Firstly, an overall plan is designed for the web user interface of the system. Then the users of the system are classified. In the light of the classification, the method of the module of power management is provided. In the last of this chapter, the page of patient register is used as an example to introduce the design of the web user interface of the site of the doctor management. Secondly, based on the special condition of the hospital, the data of the hospital has been classified to build the module. According to the classification, the source of the data is ascertained to store the medical data. Finally, the implementation of the data exchange, HAPI, a development platform which is a JAVA open source, is proposed in the last part of the thesis. After the detail explanation of the package of HAPI, the arithmetic to parser the XML is given. In the last, a flow chart to implement the commutation of the HL7 message is proposed.After the detail of the analysis and design, this thesis has finished the most the design of the system interface. The web user interface and the database are designed.
