电子病历系统的设计与实现 摘 要 随着医疗信息化水平的逐日提高，医院的不断发展与扩大，单纯采用纸张和卡片的一记录和存储方式，越来越不能满足医院病历的发展需求。所以医院电子病历系统便在这种大的发展趋势下所被提出来，以改变医院现有的管理模式，且提高医院的综合竞争力。由此可见医院电子病历的发展与建设，无疑是医院综合实力发展道路上的明智之举。本文以医院的电子病历工作站系统作为研究对象，通过软件开发工程的需求分析、总体设计、详细设计、功能实现与测试等流程，在开发技术榫架下，对医院的电子病历工作站系统进行设计与实现。 首先，进行系统的开发技术方案设计，介绍了研究的方法、关键技术与路线；进行医院电子病历系统的设计原则与分析；其次，分析了系统的建设内容需求，针对开发要求，分析医院电子病历系统的业务功能，设计了系统用户的用例图；随后，对系统进行总体设计，设计了总体架构，将架构功能分解，得到系统的应用架构、流程功能、网络结构的内容，接着设计了医院电子病历工作站软件的数据库，建立了各个主要的应用数据表，科学、合理地处理系统的数据存储方式与逻辑。最后，分析与设计了系统业务功能，面向设计与分析内容，编程实现电子病历工作站系统功能，根据业务需要设计功能模块为：医生工作站、护士工作站、系统模版，在环境下，编程实现了系统需求的各个功能，完成了电子病历系统的设计与实现。 该系统实现了网上协同管理，围绕着电子病历的浏览、查询、添加进行，维护医院电子病历数据及其它相关管理等功能，实现了电子病历管理的信息化与数字化，对医院实施的数字化的电子病历管理与规划，具有较好的实际价值。 关键词：电子病历；C/S架构；.Net 5 Abstract With the daily improvement of the level of medical informatization, the continuous development and expansion of hospitals, the simple use of a record and storage method of paper and cards, is increasingly unable to meet the development needs of hospital medical records. Therefore, the hospital electronic medical record system was proposed under such a large development trend to change the existing management mode of the hospital and improve the comprehensive competitiveness of the hospital. This shows that the development and construction of hospital electronic medical records is undoubtedly a wise move on the road of comprehensive strength development of hospitals. This paper takes the hospital's electronic medical record workstation system as the research object, through the software development project demand analysis, overall design, detailed design, function realization and testing processes, under the development technology truss, the hospital's electronic medical record workstation system design and achieve. Firstly, the system development technology design is introduced, the research methods, key technologies and routes are introduced; the design principles and analysis of the hospital electronic medical record system are carried out; secondly, the system construction content requirements are analyzed, and the hospital electronic medical records are analyzed according to the development requirements. The business function of the system is designed to use the use case diagram of the system user. Subsequently, the overall design of the system is designed, the overall architecture is designed, the architecture function is decomposed, the application structure, process function and network structure content of the system are obtained, and then the hospital electronics are designed. The database of the medical record workstation software establishes the main application data tables to scientifically and reasonably handle the data storage mode and logic of the system. Finally, the system business functions are analyzed and designed, designed and analyzed, and the functions of the electronic medical record workstation system are programmed. The functional modules are designed according to the business needs: doctor workstation, nurse workstation, system template. Under the environment, programming realizes the system requirements. The various functions have completed the design and implementation of the electronic medical record system. The system realizes online collaborative management, around the browsing, querying and adding of electronic medical records, maintaining the electronic medical record data of hospitals and other related management functions, realizing the informationization and digitization of electronic medical record management, and the digital electronic implementation of hospitals. Medical record management and planning have good practical value.
