Construct HL7 Midware-to Implement The Integration Of Medical Information System

With the development of Computer, communication Technology and Medical Image Technology in medical System, the course of hospital information manage is gone deep. HIS PACS system has been established in Medical domain,. gathering storing managing and transmitting of patient case history and medical images information are realized, which make medical information resource-sharing among hospitals possible.However, information system that most domestic hospitals adopt is designed by different developer, which causes the difference in systematic data structure and the hardware platform. So, It is difficult to share and exchange electronic information between two and more systems. At present,domestic companies developing medical information system don't obey standard and protocol.In result, medical information interconnection and information sharing among PACS and HIS - HIS system between hospitals are hindered.The paper's origin is "The Stydy on Tele-medicine Information Sharing Platform Based on PACS and Broadband Network", whose aim is to investigate HL7 standard,. A architecture of the hospital information interchange system based on HL7 is designed. The paper probes into the key technique that can merge medical systems such as HIS and PACS, HIS and HIS System based on HL7. Then, the author designs the main module of medical information exchange system based on HL72.4, which includes the HL7 message builder perse database interface and transmission module ect.By which, the basic interchange flow to implement medical information exchange is build, The data integration and sharing problem under isomerous circumstance is solved, Shading and applying medical information sharing technology based on HL7, we can advance the cause of tele-medicine and the promotion of data sharing of medical information system in China.
