【摘要】：加强医疗信息共享是国内医疗服务体系的大趋势,也是互联网医疗发展的新阶段。实验室信息管理系统(LIMS)作为医院临床检验信息交换赖以支撑的平台,它集成了各式各样的医疗仪器,不同设备之间的数据存储、表达方式差别很大,交换方式也不同,导致信息系统之间难以实现真正的数据交互共享。克服"信息孤岛",解决不同应用系统之间的互联互通问题一直是医疗领域公认的技术难点。本文研究的重点基于临床信息交换平台,围绕接口规范化研究,开展关于数据格式的统一和交换方式规范化的相关工作,旨在实现检验信息的全面共享。本文主要研究内容包括如下四点:(1)为了降低医学信息交互的复杂性,改善信息交互的效率,本文设计了基于LIMS临床检验设备接口规范化方案,为不同类型硬件设备、操作系统和数据接口之间建立起良好的信息交换通道,保证医学信息传输的快速有效性。(2)针对设备类型众多,接口形式多样的特点,从小型化、统一化、网络化入手,设计了一种能兼容支持多种不同接口类型检验设备接入的网关转换装置。网关使用嵌入式开发技术对设备接口数据进行底层解析并兼容统一,实现通用性接口转换,为简化LIMS实体对象的访问模式提供了良好的硬件平台支持。(3)根据LIMS中各实体对象之间复杂交互情况,本文在分析和理解DICOM 3.0的基础上,结合OSI模型制定了符合实验室需求的LIMS交互协议方案。重点围绕规范化数据格式和统一的数据交换方式,设计了 LIMS通讯协议体系模型,并构建服务器客户端异步网络模拟平台,进行归一化通信接口的程序设计,解决了LIMS网络中信息交换一致性问题。(4)最后本文在实验测试方面,以尿液分析仪的接入为例,通过接口程序测试了整个网络通讯环境,实现了设备到LIMS服务器的归一化协议转换,达到预期效果,验证了方案的可行性和实用性。
[Abstract]:Strengthening medical information sharing is the main trend of medical service system in China, and it is also a new stage in the development of Internet medical treatment. The laboratory information management system (LIMS), as the platform on which the hospital clinical laboratory information exchange is based, integrates various kinds of medical instruments, the data storage among different equipments, the expression way is very different, and the way of exchange is also different. It is difficult to realize real data sharing between information systems. Overcoming the "information island" and solving the problem of interconnection between different application systems have been recognized as technical difficulties in medical field. Based on the clinical information exchange platform, this paper focuses on the research of the standardization of the interface and the standardization of the data format and the standardization of the exchange mode. The purpose of this study is to achieve the overall sharing of the test information. The main contents of this paper are as follows: (1) in order to reduce the complexity of medical information interaction and improve the efficiency of information exchange, this paper designs a standardized interface scheme for different types of hardware devices based on LIMS. A good information exchange channel is established between the operating system and the data interface to ensure the rapid and effective transmission of medical information. (2) aiming at the characteristics of numerous equipment types and various interface forms, the paper starts with miniaturization, unification and networking. In this paper, a gateway conversion device is designed, which can support the access of many different interface type checking devices. The gateway uses embedded development technology to parse the device interface data at the bottom and achieve universal interface conversion. In order to simplify the access pattern of LIMS entity object, it provides a good hardware platform support. (3) according to the complex interaction between each entity object in LIMS, this paper analyzes and understands DICOM 3.0. Based on the OSI model, a LIMS interactive protocol is developed to meet the needs of the laboratory. Focusing on the standardized data format and the unified data exchange mode, the LIMS communication protocol system model is designed, and the asynchronous network simulation platform on the client side of the server is constructed, and the program design of the normalized communication interface is carried out. The problem of information exchange consistency in LIMS network is solved. (4) in the aspect of experimental test, taking the access of urine analyzer as an example, the whole network communication environment is tested by interface program. The normalized protocol conversion from device to LIMS server is realized, and the expected effect is achieved, and the feasibility and practicability of the scheme are verified.
