[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.
