With the deepening of hospital intelligence and informatization, we have also encountered some defects and deficiencies in actual construction. Often builders are very concerned about whether hospitals can reach the international advanced level immediately or in one step, so they expect too much in construction. However, in actual planning, due to various constraints such as funds, they have to reduce the input of some systems. Compared with network and cabling system, they often ignore the importance of integrated cabling system and its computer network system. This is the starting point of this paper. This paper will focus on discussing some experiences and lessons of integrated wiring system in hospital intelligence and information construction. By putting forward some viewpoints, it may give some inspiration and help to the readers of this article.
1. Positioning of Integrated Wiring System in Hospital Intelligent Information System
Hospital intelligent system is located in the construction of building weak current infrastructure, which usually includes building automatic control system (BA), public safety management (SA), fire alarm and fire control linkage (FA), broadcasting (PA), cable television (CATV), integrated wiring (PDS) and computer network communication system. In addition, there are some intelligent platforms specifically for hospitals, such as
Hospital information platform is located in the application layer of network, which realizes the networking of information terminals, centralized processing, storage and sharing of information through computer network technology, thus improving the efficiency and effect of diagnosis and treatment and improving management means. Information-specific information platforms generally include: hospital information management system (HIS), clinical information system (CIS), medical imaging system (PACS), radiation information system (RIS), telemedicine system, etc. Because the general concept of hospital intelligent system usually includes more than a dozen subsystems, and the hospital information system (MIS) platform usually includes more than a dozen different functional modules, we often hope to reach the goal in one step at the initial stage of construction. Judging from the current construction experience, such expectations are difficult to achieve and often backfire. The reason is that the builders of intelligent systems often don't understand hospital informatization and medical services. The builder of information system pays attention to the demand of application layer, and often thinks that the bottom system should be built with intelligent system. Hospital users usually lack experience in these two aspects, which leads to the lack of macro-planning between systems during construction, and often pay attention to details while ignoring the whole. Once this system is put into use in the future, it is extremely difficult to adjust it.
To sum up, we think that the hospital intelligent and information system should be planned and considered from the overall and long-term perspective when it is initially built. First of all, we should make every effort to build a computer communication bearing platform based on network wiring, which is in line with the long-term development of hospital intelligence and informatization and has enough room for expansion. This is the most important thing, and the intelligent and information-based system should be planned from the most important and essential subsystems and functional modules in the early stage, distributed in stages, and gradually completed in a period of time according to the characteristics of the hospital itself, accompanied by the improvement of users' own abilities. Only in this way, can we finally build an efficient, intelligent and information-based system that meets the actual needs. At the same time, in this construction period, the computer communication bearing platform with long-term vision has always been the cornerstone of all this success.
2. How to plan a suitable hospital integrated wiring system?
2. 1 The complexity of hospital informatization puts high demands on the network.
At present, how to build a successful hospital information platform faces many problems that need to be solved urgently. In the latest national standard GB/T 503 14-2006, the intelligent construction of hospitals is clearly defined. It can be seen that the hospital information network platform is almost the most complex of all networks, because the hospital computer network is the platform for hospital business operation, and it is of great significance that patients' medical information and various hospital business management information run on it. It can be seen that the higher the informatization level of each link in the medical process, the higher the requirements for the 24-hour uninterrupted safe and reliable operation of the computer network.
2.2 Top-down planning-The integrated wiring system is recommended to be set up separately.
Based on the characteristics of hospital computer network architecture, we suggest that the network wiring system be divided into several physically isolated network systems (Note: Of course, it is not unreasonable to adopt a network according to the actual situation, but it needs to be supported by sufficient technical capabilities in network security. )
A. Data Intranet (medical information network)-Hospital business systems running on this network, such as his, LIS and PACS, complete the transmission and processing of information such as office automation, administrative management, medical management and ward management in the hospital. We can understand that the hospital's production network is a vital network of the hospital, so the comprehensive wiring is the first. Because this network involves the internal information of the hospital and the personal privacy of patients, it should be strictly physically isolated from the outside world. Because of the particularity of hospital application, its network structure is often very complicated. In addition to supporting the hospital MIS network system, in some key areas, we should also consider building a regional private network for the region, and consider whether to establish external interfaces or physical isolation according to the actual situation.
B. Data extranet (Internet)-Internet connection is realized, public hospital information is released to the outside world through the Internet platform, and medical personnel can query information online, send and receive e-mails, remote training and telemedicine applications. The importance of the external network is relatively low, so it is enough to meet the functional requirements when planning and wiring.
C. Voice network (internal telephone, public telephone)-realize voice communication and support applications such as digital, ISDN telephone, IP telephone and future videophone;
conclusion
In practical engineering, we often see that the design of computer network and wiring system is relatively simple, which often cannot meet the high standard requirements of hospital information application system platform. As a result, after the project won the bid, there was a big rectification when the design was deepened, which often exceeded the budget and put users in a dilemma. Therefore, in the early stage of hospital project construction, we should pay full attention to the relationship between hospital information platform and intelligent platform, and the functional positioning is very important, which is conducive to the rational allocation of investment and the use of limited funds in key positions and key businesses. At the same time, because the hospital information platform is the production platform of the hospital and the computer network is the transmission system of hospital information application, it should be considered emphatically; Integrated wiring system is the physical bearing platform of computer network system. At the same time, due to the long-term unchangeable characteristics of the integrated wiring system once installed, more attention should be paid to the support of current and future applications in planning.
