基于多层架构的临床实验室信息系统的结构设计与实现

Design and Realization of Clinical Laboratory Information System Based on Multi-layer Architecture

目的:设计基于多层架构的临床实验室信息系统,以便系统、高效、准确地管理医院的临床检验工作,简化工作流程,提高医院信息化服务水平。方法:软件的设计采用Powerbuilder12,后台数据库采用Oracle10g,重点解决了本院现有HIS与新建LIS 2个系统对接的数据库关联点。结果:经过测试,系统各项功能均达到设计要求,数据传输准确、运行稳定。结论:LIS保证了检验数据的准确性、及时性、查询的便利性,提高了工作效率,优化了临床检验工作流程,方便了患者就医,提高了医疗部门的服务质量。

Objective To design a clinical laboratory information system（LIS） based on multi-layer architecture to simplify the work flow.Methods The interface between coexisting HIS and developed LIS was realized,with Powerbuilder12 for software design and Oracle10g for background database.Results Trials proved the LIS could meet the desired requirements.Conclusion The accuracy,timeliness and convenience of clinical laboratory examination are improved,with the efficiency enhanced and working flow optimized.
