Design and research of a highly integrated hospital management information system
Overview
Hospital Information System (HIS) is a frontier science that integrates medicine, information, management, computer and other disciplines, and has been widely used in developed countries, creating good social and economic benefits. HIS is the necessary technical support and infrastructure for modern hospital operation. The purpose of realizing HIS is to strengthen hospital management, improve hospital work efficiency and medical quality by more modern, scientific and standardized means, so as to establish a new image of modern hospital, which is also the inevitable direction of hospital development in the future.
in order to meet the needs of hospital development in China and make Chinese medicine integrate with world science and technology as soon as possible, Dalian Huiyuan Electronic System Engineering Co., Ltd. concentrated a lot of manpower and material resources, learned from the advanced experience of HIS at home and abroad, and combined with the traditional management mode and actual needs of domestic hospitals, developed the hospital management information system. In 21, Huiyuan Hospital Management Information System was recognized as a software product by Dalian Information Industry Bureau. This product is a hospital management information system that is truly suitable for China's national conditions, and it is the only hospital information system with independent intellectual property rights that can share the world with IBM's hospital information system solutions in China.
overview of system design
the implementation of this system will build an enterprise-level computer network system in the whole hospital, and build an enterprise-level application system based on it, so as to realize the smooth circulation and high enjoyment of all kinds of information such as people, finances and materials in the whole hospital, and lay a solid foundation for the modernization of management level and the accuracy of leadership decision-making in the whole hospital. The system has the characteristics of maturity, stability, reliability, long application period and good expansibility, and can be tailored according to the characteristics of each hospital. The system has been successfully used in a series of hospitals such as pulandian city First People's Hospital, zhuanghe city First People's Hospital, Dalian Zhongshan Hospital, gaizhou city Central Hospital, Penglai People's Hospital, Dandong Chinese Medicine Hospital, Fushun Chinese Medicine Hospital, Tieling Chinese Medicine Hospital, Tieling County Hospital, Heilongjiang Hulan County Chinese Medicine Hospital, Dalian University Affiliated Hospital, Wafangdian First People's Hospital, etc. It has achieved good social and economic benefits for all hospitals, and has also been well received by customers.
function of application software
(1) table of microcomputer equipment for various functional departments of the hospital
The whole system consists of a server and several workstations, and each subsystem runs in coordination on the network, which provides flexible business inquiry among departments and strict authority control. Each subsystem provides a common query function, and each subsystem can only use the functions it has the right to call under this function. The data shared between networks is real-time, so as to avoid data inconsistency between departments.
(II) Functional view of hospital management subsystem
Hospital management subsystem (HIS) usually includes outpatient service and hospitalization, and the main line of management is drugs and the amount of money collected.
1. Description of the view:
The above is the functional view of various functional departments of the hospital. The departments in the box are departments equipped with computers; The departments in the parallel line are related departments in the hospital. What is passed between departments is data information. Because the personnel section and general affairs section are relatively independent, they are not included.

Hardware platform system design
Hardware is the basis of system implementation. In the design scheme, we take into account the various requirements and characteristics of system implementation and the actual situation of the hospital. When selecting hardware, we must meet the system requirements, give consideration to the system performance, and take the principle of the highest cost performance as the principle, so that the system can achieve the best and most economical scheme.
1. Server
The main server is the heart of the system, and all workstations in the system must exchange information with it, so it must be fast, stable and reliable in quality.
2. Workstation
The selection of workstations is based on ensuring the high-speed operation and high reliability of the network. At the same time, considering the specific actual situation of the hospital, it can meet the requirements of the system and save limited funds for the hospital itself.
3. Printer
We mainly choose printers with fast printing speed, durability and low running cost. The products of world-famous printer manufacturers fully meet its requirements.
4. distribution power supply (UPS)
when the power supply is interrupted, if the network is running, it may lead to data loss and equipment damage, thus causing irreparable losses. Therefore, it is necessary to ensure the uninterrupted operation of the machine, but it can only be provided for a short period of time and give an alarm.
network design
Hospital management system is a comprehensive system. Therefore, in the design scheme, Dalian Huiyuan Electronic System Engineering Co., Ltd. takes into account the characteristics of wide management, many departments and timely information exchange requirements, and takes into account the actual situation of the hospital. The network adopts an international standard star network topology structure, which has the characteristics of flexible expansion, convenient maintenance, stable operation, good interconnection and reasonable performance-price ratio, and is the best and most economical scheme adopted by the computer network system.
1. Integrated wiring
Cable is the lifeline of computer network and the artery for transmitting information. If the line is damaged due to quality problems, the network will be completely paralyzed and stop working. Therefore, we adopt the integrated wiring scheme of building automation in the design, strictly in accordance with the technical requirements of integrated wiring, so as to improve the quality and stability of the line. At the same time, it can be used for language transmission, which is convenient for users to choose freely. According to the field situation, cables can be connected to RJ-45 sockets on the wall, or RJ-45 plugs can be directly connected to workstations, which is convenient for maintenance and expansion.
2. Network devices
Network devices are mainly switches and hubs, which are intermediate devices connecting the main server and workstations. Switch is the core equipment in the network, which provides a fast connection between servers and workstations. There is also a hardware device in the network, that is, network adapter, also known as network card, which is used to connect each workstation with cables. Because the network card is the main equipment connecting each workstation with the network, in order to make the workstation work stably, a network card with good compatibility and high reliability must be guaranteed.
3. Network management
We use the above network scheme to make full use of network resources and facilitate management and maintenance. In the planning, we make the workstations not depend on each other, but connect with each other. That is, the running state of one workstation does not affect the normal operation of other workstations, which improves the reliability of the network.
database system and system management platform
1. Database system
Hospital management information system has a huge amount of data and strong real-time performance, so it is necessary to choose an efficient and stable large-scale database system when selecting database systems.
2. Network operating system
Network operating system is a layer of software platform based on network hardware equipment, without which a reasonable computer network system cannot be formed. Network operating system is an important part of network, because it is stable and closely cooperates with database system.
