1 the importance of information technology
With the rapid progress of information technology and health care system reform to deepen the reform, modernization, digitalization, intelligent hospitals in-depth development has been inevitable, the degree of information technology in the hospital for the development of the road to show more important. Hospital network planning, integrated management of computer rooms, hospital information management system (HIS), electronic medical records (EMR), image archiving and communication system (PACS), laboratory information system (LIS), telemedicine, OA office are showing us the charm of digitalization and the intangible value of information technology.
2 Information Technology Engineering Infrastructure
2.1 Network Planning, Design and Implementation
Integrated cabling old shape: the use of overhead multimode optical fiber between buildings, connected to the central computer room through fiber optic transceivers; the use of Category 5 twisted-pair cables between floors, through the 100 megawatt unmanaged Layer 2 switches or hubs to connect; the planning, design and integrated cabling: in the spirit of Planning, design and comprehensive cabling: Based on the guiding principle of "safety, practicality, economy and reasonableness", a systematic, detailed and comprehensive survey, analysis and research were conducted on the network of the whole hospital. The final choice and implementation of the use of single-mode fiber optic cabling between buildings, floors using Category 6 twisted-pair cable, the core room is arranged in the hospital's central location on the sixth floor of the outpatient building, the optical fiber through the fiber optic switch fiber modules converge to the core switch in the room. And all optical fibers into the ground, and reserved pipe wells for future maintenance (see Figure 1, 2, 3).
2.2 Server room planning, input and implementation
2.2.1 Server room infrastructure implementation according to the security requirements of the server room, unified server room grounding, lightning, waterproofing the ground, moisture-proofing, installation of access control and monitoring, equipped with fire and smoke alarm devices. It is equipped with an uninterruptible power supply of the Santak 3C20KS model. In view of the cost considerations, configured 1 set of ordinary precision air conditioning to regulate the temperature and humidity of the server room. In view of the importance of electricity, 2-way utility power supply was selected.
2.2.2 server implementation after comprehensive consideration of the server unified purchase of IBM manufacturers of 3850 and 3650 two models, which HIS server throughout the entire process of patient care, the importance of self-evident, its security and stability requirements are very high, and finally chose two sets of IBM 3850 and did a dual hot standby. The PACS database server and the social security front-end machine also use 1 IBM 3850 respectively, and other domain control servers, LIS servers, PACS application servers, EMR servers, OA servers, antivirus servers and so on are unified to use the IBM 3650, of which the database servers are unified to use the Red Flag operating system. The other servers use windows2008R2 operating system.
2.2.3 Storage method selection: SAN technology With the increasing data of the hospital network and frequent data exchange, the hospital also realized that the original DAS (Direct Attached Storage) method is difficult to meet the increasing data storage performance requirements. Comprehensive consideration, the choice and use of popular data storage network is SAN (StorageAreaNetwork, Storage Area Network), the entire storage as a separate network with the server where the enterprise LAN connection. One of the fiber optic switch model for the IBMSAN24B and storage model for the IBM DS5020, and both achieve a dual-machine hot standby function. Performance and security greatly improved.
2.2.4 Storage and fiber optic switch configuration storage LUN division, fiber optic switch ZONE division. The specific division of storage space needs to be divided in accordance with the needs of the hospital information system, the two storage configuration between synchronous replication function, fiber optic switches and storage of the two controllers cross-interconnection between the ZONE division so that the servers and the storage of one-to-one correspondence.
2.2.5 Core Switch Configuration Two H3C7506E-V core switches using IRF technology, through the 10 Gigabit module for stacking, virtualization into a device to use, each access switch through the two uplink lines, respectively, with the two core switches interconnected, the two uplink lines through the link aggregation function aggregated into a Portgroup, the core end also The two uplinks are aggregated into a Portgroup through link aggregation, and the core terminal is also aggregated into a Portgroup through link aggregation, which ensures that the normal operation of the whole network will not be affected in the event of a line failure.
3 use after infrastructure construction
After the completion of infrastructure construction, the basic realization of the hospital modernization, information technology, security, high efficiency, energy saving and other humanities office environment requirements. Network security and reliability: the hospital network has implemented a physical isolation program for internal and external networks, combined with firewalls, network version of antivirus protection, provides a strong guarantee of data security. Redundant management is realized for important equipment, which greatly improves the coefficient of network and data security. Advanced and practical network: single-mode fiber transmission distance, high transmission bandwidth, low BER, high stability characteristics, coupled with fiber optic module connection through the switch makes network transmission more efficient, safe and convenient.
Ease of management and scalability of the network: The core switches use two H3C7506E-V, and the access layer switches all use H3C5120, which realizes remote maintenance of the switches and improves the ease of management and security of the network, and provides a basis for the expansion of the network. Among the 8-core single-mode fiber, in addition to 4 cores (one pair of transceiver and one pair of redundant) used in the intranet and 2 cores used in the extranet, there are still 2 cores left that can be used for emergency and redundancy. Efficient and convenient network: The original network client has to wait for several minutes to query or write the patient's medical data, but now it takes only a few seconds, which greatly shortens the time for medical treatment. In a shorter period of time to carry out fruitful classification, analysis of medical data, for the leadership of scientific decision-making to provide timely early warning services, so that the statistical system has become more efficient, convenient, and the intangible value it produces for the management of the hospital to provide an important scientific basis.
4 insufficient information technology construction
The performance and stability of the ordinary precision air conditioning used in the computer room is relatively poor, air conditioning hardware failure can lead to higher temperatures in the computer room, the server is down, the network is paralyzed, and the severity of the problem can be imagined. It is recommended that the air conditioner use 2 units, the implementation of dual machines working simultaneously to improve the safe operation of the server room. No intrusion detection system is installed, such as palm hospitals, booking appointments, remote consultation direct call intranet PACS images and other system information can not be realized, it is recommended to purchase. All kinds of database and application servers in the server room are more than 15, which are complicated to operate and not easy to manage, and only important servers achieve redundancy, and the overall security cannot be guaranteed, and it is recommended to use server virtualization technology. Talent team construction is insufficient, personnel technical level is not uniform, it is recommended to strengthen the technical level of personnel learning and assessment.
5 Conclusion
While Qingdao Infectious Diseases Hospital has made some achievements in informationization construction, there is still a big gap between the requirements of deepening the reform of the medical system and the informationization construction of other general hospitals, and the next step is that we will continue to deepen our research and study, strengthen the investment in hardware, and improve the functions of software systems, so as to promote the construction of informationization of hospitals and to promote the rapid and healthy development of hospitals. rapid and healthy development.
