HIS与排队叫号系统接口设计

目的：整合医院信息系统（HIS）与专业的硬件排队叫号系统，使排队叫号系统更安全可靠。方法比较接口实现的多种方法，如动态链接库调用（DLL）、WebService、数据库中间表等方法，最终选择数据库中间表方法设计门诊输液流程中HIS与排队叫号系统的接口。结果 HIS与排队叫号系统的接口采取数据库中间表的方法更符合实际环境，开发方法简单，开发时间短，有一定的推广价值和借鉴意义。结论医院各信息系统之间的接口有多种方式，要根据具体情况具体分析应用。

Design of the Interface Between HIS and Queuing-Calling System

Objective To integrate HIS and queuing-calling system to enhance the safety and reliability of queuing-calling system.Methods Based on the comparison of various implementation methods of interface such as dynamic link library, WebService, database middle table, the detailed design and implement methods of the interface between HIS and queuing-calling system during outpatient infusion process were given.Results The development method with simpler steps and shorter time of the interface by using database middle table conforms to the actual environment, which should be promoted and referred.Conclusion The interface for different information systems in the hospital should be implemented by using the optimum implementation method which can be choosed according to speciifc circumstances.
