本研究从实际临床问题出发，对患者信息管理系统的结构设计、功能设计以及开发工具等多方面进行了深入的研究与探讨。本系统采用 Microsoft Visual Studio 2017 作为主要的系统开发工具，设计语言使用面向对象的C#作为开发语言，后台数据库选择微软公司的 SQL Server 2012 作为数据库基础。临床工作者能对患者的信息进行录入、更改、查询，针对具体疾病可进行相应检验单的申请，药物处方的开具以及会诊单的申请等多种功能。系统设计的自动定时备份、导入导出功能，可以及时备份患者数据信息，有效提高数据的安全性。本系统的应用极大地优化了医务工作者的工作流程，提高了其临床工作效率。

To solve the clinical problems, this paper studies and discusses on the structure design, function design and development tools of the patient information management system. This system uses Microsoft Visual Studio 2017 as the development tool, object-oriented C# as the design language, and SQL Server 2012 as the database. The clinical worker can enter, change and query the information of patients, and can perform various functions such as the application of the corresponding inspection document, the issuance of the drug prescription, and the application of the consultation document for the specific disease. The automatic timing backup of the system design, import and export function, can timely back up the data information of patients, and effectively improve the safety of data. The application of the system greatly optimizes the workflow of the medical workers and improves the clinical working efficiency.
