基于HL7的LIS与HIS集成改造

摘要

This paper introduces the integrated reform process of Laboratory information System (US) and Hospital Information System (HIS). This integrated reform uses middleware of HL7 engine to proceed the integration among heterogeneous systems, namely, added an application server in both sides, and installed service components. In this way, functions of data access, data processing, TCP communication, HL7 communication and so on were realized. Comparing with middle library model integration in the past, this integration pattern greatly improves the normalization and independence. Based on the middleware of HL7 engine, the integration among heterogeneous systems will be the development tendency in the future.%本文介绍了我院的实验室信息系统( LIS)与医院信息系统(HIS)的集成改造过程.此次集成改造采用HL7引擎的中间件进行异构系统之间的集成,即在数据共享双方各增加一个应用服务器,安装服务组件,实现数据存取、数据加工、TCP通信和HL7通信等功能.此次集成方式与以往的中间库模式集成相比,大大提高了系统的规范性和独立性.基于HL7引擎这一中间件的异构系统之间的集成,必将成为今后的发展趋势.
