基于健康信息交换第七层协议的心电图仪信息化研究

The information research of electrocardiography based on Health Level Seven

背景:医疗仪器种类繁多且数据结构各异,缺乏统一的交互标准,严重阻碍了医疗仪器的信息化共享。目的:以心电图仪为研究对象,应用健康信息交换第七层协议(Health Level Seven,HL7)信息化标准实现其信息化交互,探讨基于HL7的医疗仪器信息化交互的可行性和优越性。方法:分析比较现有的数据交换标准,以HL7注释心电图作为心电图仪的交互标准,以消息引擎方式在WINCE嵌入式平台下采用.Net和可扩展标记语言关键技术实现心电图仪的标准心电数据交换协议消息解释和HL7信息化编码,并验证其有效性。结果与结论:对信息化编码后的数据成功通过HL7结构的有效性验证,心电图数据能解析并正确显示。研究结果验证了心电图仪HL7信息化的可行性,且实现方法具有较好的可扩展性和通用性。

BACKGROUND：The heterogeneous data structures in various kinds of medical instruments and lack of unified exchange standard which seriously hamper the data sharing of medical instruments.OBJECTIVE：To investigate the feasibility and superiority of Health Level Seven（HL7） based communications between various medical instruments and medical information systems as HL7 is applied in this study as the exchange standard of information interaction on electrocardiograph.METHODS：HL7 electrocardiograph was used as the interaction standard of electrocardiograph to analyze and compare the current data exchange standards.Net compact framework and extensible Markup Language core techniques were applied in WINCE embedded platform with message engine,and realized the electrocardiographic standard communication protocol for computer-assisted electrocardiography explanation and HL7 information encoding and verified its effectiveness.RESULTS AND CONCLUSION：The encoded data of electrocardiograph was successfully converted to the HL7 electrocardiograph format and displayed correctly,which has been validated by using the HL7 schema validity.The feasibility of HL7-based research of electrocardiograph information has been confirmed.The realization method is featured by practicability,expandability and universality.
