ABSTRACT
In this paper, the theory of complex adaptive system (CAS) and its modeling method are introduced. The complex characters of the hospital system is analyzed. The agile manufacturing and cell reconstruction technologies are used to reconstruct the hospital system. Then we set forth a research for simulation of hospital system based on the methodology of Multi-Agent technology and high level architecture (HLA). Finally, a simulation framework based on HLA for hospital system is presented.

Objective To avoid medical mistake,improve service quality of medical care,insure the security of patients. Methods The wireless Lan was deployed in ward to implement the scheme of using wireless Lan and avoid medical mistake,and then use wireless nursing system to prove it. Results This scheme can reduce the work intensity of medical staff,decrease the probability of medical mistake,and improve the service quality of medical care. Conclusion The wireless technology can avoid medical mistake effectively.
ABSTRACT
Objective To monitor the hospital computer room in real time; ensure the normal running of hospital information system; overcome the disadvantages of wired monitor system. Methods Zigbee was used to build a wireless sensor network. Wireless monitor system for hospital computer room was realized. Results By exerting the advantages of zigbee, hospital computer room was monitored more effectually and the workload of the computer room keeper was reduced. Conclusion Using Hospital computer wireless monitor system based on zigbee can achieve the uniform management and monitoring effectually.
ABSTRACT
Objective To build high availability cluster using VMware to improve availability of hospital information system.Methods Virtual machines were installed in VMware server to act as backup servers.High availability software continuously detected status of physical servers using heartbeat signals.Results When physical servers failed,high availability cluster switched services automatically.The business switched to virtual machine quickly and smoothly.Conclusion High availability cluster based on VMware can improve HIS availability and lower implementation costs effectively.
ABSTRACT
Objective To build a regional cooperative healthcare system in order to make the best use of the limited medical resources,reduce the cost,and improve the quality of medical treatment.Methods Data warehouse and virtual database were used to build regional data center and realize data integration of hospital information system.Upon this foundation,a web service integration of hospital information system based on SOA was realized.Results This design scheme realized the effective management and integration of huge information resources,and managed the medical workflow effectively.Conclusion This design scheme provides the regional cooperative healthcare system with the characteristics of modularization and expansibility.Hierarchy architecture enhances the stability of the system.
ABSTRACT
Objective To apply the techniques of network isolation and secure data exchange network to hospital information system.Methods Network isolation and secure data exchange were used to do data exchange and synchronization between two networks.Results A LIS result query system was designed and realized based on this technology.Conclusion Secure data exchange in HIS can be realized effectively by using the techniques of network isolation and secure data exchange and it has good foreground in hospital information system.[Chinese Medical Equipment Journal,2008,29(2):45-47]
ABSTRACT
Objective To build an architecture for medical information integration based on SOA(Service-Oriented Architecture)by analyzing the characters of medical information integration and the integration technology of SOA. Methods Virtual database was built by XML Schema mapping for conform share of medical data based on XML technology. The method and principle of Web Services for medical information were researched and built. Results Medical information systems could uniformly exchange information based on standards of Web Services, and the conform medical information share mode was realized. Conclusion The integration of medical information systems based on SOA not only has the characteristics of loose-coupling and customization agility but also makes information share possible because of conform mode.
