Abstract: Data can not be communicated so well according to the unified data standards among the health information systems in our country that information sharing is impeded. On the basis of the HL7 V2.x (health level seven Version2.x) protocol of health information communication standard and the theory of HL7V2.x message parsing, the method in which data in the database fields is extracted to generate HL7V2.x messages and parsed message information is stored in the specific database is introduced in detail. Then an optimized model of the message store and the message generation is brought forward. In this model, mapping files are designed to save much time in redundant manual configurations and the hash table is used as a data structure during the process of message generation to make it more efficient. Simulation experiment results show the feasibility of the model.

摘要： 针对我国医疗信息系统不能很好地按照统一数据标准进行通信而阻碍医疗信息共享的问题，基于现有医疗信息通信标准HL7V2.x和消息解析理论，设计了将已有数据库中的字段构建成标准HL7V2.x消息和解析后的消息存储到数据库的方法。在此基础上，提出了一种优化消息构建和消息存储的模型，通过使用映射文件节省重复手工配置时间；并利用哈希表作为数据结构，从而提高消息构建的效率。最后通过仿真实验研究验证了该模型的可行性。
