目的:优化消化内镜系统的病理检查申请流程,避免重复录入数据.方法:首先分析消化内镜检查工作站与病理检查申请软件的主要功能,从中归纳出系统集成需求,并基于Windows自定义消息机制设计系统的集成框架.然后,详细阐述动态链接库文件的创建及其在PowerBuilder中的声明和使用、进程间消息的发送和接收等实现技术.结果:基于Windows自定义消息,较好地完成消化内镜系统集成,优化病理检查申请流程,简化数据录入操作.结论:基于Windows自定义消息的系统集成方法可方便地实现进程间的数据共享和信息交换,但尚未彻底解决软件界面集成问题.%Objective To optimize pathology examination applying process and avoid inputting the information repeatedly. Methods Firstly, the software functions of the digestive endoscopy information system and pathology examination applying system were described in broad detail in order to fully identify requirements. Next the system integrated infrastructure based on the Windows messages was designed. Finally, many advanced techniques were extensively used in the system, such as how to create dynamic link library and how to declare and utilize it in PowerBuilder, and how to send/receive Windows messages between the processes. Results The integrated system was suitable for optimizing workflow, so it was applied in digestive endoscopy center successfully. Conclusion Data exchange and information sharing have been achieved through the integrated system based on Windows custom messages, but the software interface integration should be paid much moreattention to.
