Design And Implementation Of A Physical Examination System For Military Based On .NET

With the rapid development of social progress and economic and the continuous improvement of people’s quality of life, the health examination as a means of prevention of disease, which people pay more and more attention to[1-2].With the development of medical information, the application of the information system will promote the development of healthy. Now, the health examination is established in modern biomedicine and information technology management mode, which is the whole process of comprehensive monitoring, analysis, evaluation, prediction, prevention and maintenance of individual or group health risk factors from the point of view of society, psychology and Biology[3].Military hospitals, nursing homes and government outpatient department units bear the military organs of the head of health physical examination, the physical examination of the local units and the personal check medical support tasks. With the development of medical information technology, especially the development of military medical information, a physical examination system in accordance with these units is urgently for the information, standardized management of the medical process, medical information for the members of the army.Military medical examination system is a part of the hospital medical information management system, it follows the integration of military information system architecture standards and the military outpatient information system construction requirements. On the basis of military health data structure, the system mainly provides services to the military organs hospital medical center. Through the investigation of the physical examination center of Guangzhou Military Region, The military medical system which is put into use now can not meet the needs of the medical institutions in the military area in the realization of technology, functional process design, user experience:(1) Difficulties in upgrading and maintenance of the original military medical examination system:The original system used PowerBulder language as the development language which has not been popular in recent years. Using PowerBulder as the development language caused the lack of developer to follow-up the system maintenance upgrades. The original system used a layer of architecture development, resulting in different functions of the code confusion. The developer code transition difficulties lead to system upgrade and maintenance difficulties.(2)The system flow, functional design, user experience can not follow the development of hospital medical center in a timely manner, which has been unable to meet the current users’needs:Nowadays, the physical examination center of the military organs medical institutions bears the characteristics of military as well as the local residents’health examination tasks, which is not reflected in the system process. In the functional design, the user management lack of the consideration of medical doctors of the department authority. The lack of the automatic analysis of physical examination results is obvious. The physical examination information is incomplete because of the lack of interface with the HIS, the PACS and the LIS. In the management function design, lacks the function of practical cost accounting and the inquiry for historical result and so on. In the user’s physical examination, the style of XP system interface does not match the current win7 systems style, which results a decline in the user experience.(3)The lack of system version automatic update program:Updating the system by the method of manual copying program files would result in the following problems:Firstly, version updating is not timely. When the version changes, the physical examination system of each computer program may be not on the same time. It may lead to user errors or the occurrence of the phenomenon of the program crash. Secondly, the efficiency of program updating is low that leads to a waste of human resources because of the operation of version updating of each computers needing someone to follow upIn order to deal with the new situation of medical information development and meet the demand for future system expansion, and better for military health examination and provide information management services, this paper contacted with the Guangzhou military organs outpatient department of research and development, identified the following research and development goals for the health physical examination information management system goals:(1) Select the appropriate technology:the system implementation language, architecture and other technologies, which is the foundation of the system. (2) Based on the military authorities medical examination process and function, designs and implements the user system flow, function design and user experience that are reasonable and close to the user needs. (3) Design and implement the feature of the system version of the automatic update.On the realization of technology, this paper realized the function of the system by the technology of C# Windows Forms based on the platform of the visual studio.net, and the oracle 11g technology, as well as the C/S three layer architecture+ factory pattern. C# language is an object-oriented programming language developed by Microsoft, it can offer the rapid development of application program based on.NET platform. Also a large number of.NET class library provided by Microsoft to help developers to develop, that greatly improves the speed of the system development. Oracle database is a relational database management system which is currently the most popular, with good portability, easy to use, powerful features, that makes it a reasonable choice for the medical information system continues to expand the scale. The three layer C/S structure divides code into three layers logically application. The core business logic is encapsulated in the form of components by the structure, so that the coupling between layers is reduced to a minimum. To build a data access layer using abstract factory pattern design, can create a hidden database access object, which makes the system switch in different database platform becomes possible that improves the scalability of the system.This paper considered design of the overall of the system, the function of the system and the user experience of the system according to user needs. This paper considered a variety of medical model in the overall design of the system. The design of two operation entrance for the army volunteers and local volunteers can meet the different needs of medical institutions, which enhanced the adaptability of the system. In the realization of the system function, we pay attention to improve the working efficiency of the medical center and medical information integrity. Adding the functions of analysising intelligent examination results, PACS interface, quering the previous physical examination results and so on makes the army health archives management more standardized and is proved to be practical. In the system the user experience, this paper adopted the Microsoft Office Fluent user interface navigation bar, added the function of memory and fast switching window, so that improved the friendly interface of user and system software experience.The physical examination system needs to install on more than one computers in examination center. In order to solve the problem of low efficiency and not timely synchronization caused by the manual method of previous updates, this paper has made the following research on the automatic update function deployment:Using database as the media for transferring program update files and the foundation of binary stream files in the database access technology, we have developed and released program automatically updates two components:The release process is responsible for uploading and updating files, and the program for automatically updating is to complete the test version number and download the update file.Innovation and advantage of this system lies in the following aspects:(1) Has a good and easy maintenance and scalability. Using C# Winform language base on the visual studio.net platform and C/S three tier architecture, which makes the system in the clear code structure and clear hierarchical logic, that lays the key technology foundation for the follow-up maintenance. The data access layer based on the abstract factory pattern design can make the system switch between different database platforms freely. According to the situation that different hospitals may use different database management system, the system has been developed different database management system access module which allows the system to quickly complete the deployment and put into use, also can reduce the transfer of data between the database platform, to avoid data loss and ensure hospital case data integrity.(2) The process is simple, functional intelligence, user operation is convenient. This system for the first time put forward military personnel and local staff to separate registration, fees, the report of the two sets of processes, making the system more convenient for doctors and nurses to operate. The process is more direct and clear. The research results of the discriminant function of smart, intelligent generation department review and screening recommendations function, makes the doctor’s workload greatly reduced, and improve the efficiency of the examination. The the function of inquiring and analysising the previous physical examination results provides doctors with more long-term real data to help track the physical condition of the physical examination which is the key means to monitor the health of the military cadres. The system can be connected with HIS/PACS/LIS health system, which makes the medical data flow more standardized and the physical examination information more complete. Management support functions including user management, cost accounting, dictionary settings, etc., enhances the management of the system value and the management of the system value.(3) This paper has implemented the system version of the automatic update program. The implementation of the system version automatic update program makes medical system update faster and more accurate, saving human resources, and also to ensure the timeliness of the update and synchronization. The research in this paper of system version automatic update program is suitable for many kinds of systems, and it has portability and reusability.In summary, this paper based on current health examination, medical information management and technology development trend and main demand of the medical information, introduces the main development technology of the system, tool, and program architecture from the army medical health information management status and needs of the starting. This paper firstly describes the design and implementation of the system and describes the system’s overall process design, key functional design and implementation and user experience and friendly interface design. Secondly, this paper describes the system version auto update program of research and implementation in details. Finally this paper summarizes the design,the development and the innovation of the system, and analysis possible deficiencies, and looks for health information technology in the military health examination system development.
