1.1 Motorola mobile clinical information system network structure
As shown in the figure on the right, the entire system architecture is based on the original local area network (LAN) of the hospital. The application server is connected to the LAN in the data center to provide system application services; the Motorola RFS7000 wireless switch is connected to the core switch in the host room; the LAN Configure Motorola Airdefense on it to provide system security and management services; configure the corresponding number of APs on the floor channel according to the channel length; configure the power supply switch on the corresponding floor according to the number of APs and the length of the network cable connecting the AP; configure the application front end at the medical staff (EDA) equipment. Thus, a complete mobile clinical information system is established. Through the above topology diagram, it can be clearly seen that the construction of this system has not made any changes to the original wired network of the hospital. Based on the original network (LAN), we have extended the network information point to the clinical and mobile By the medical staff.
2. Technical characteristics
2.1 Application advantages
(1) Mobile electronic medical records, pushing electronic medical records from desktop applications to mobile applications
At present, major domestic hospitals have started to build electronic medical record systems. As the electronicization of medical documents is gradually deepened, the entry and recall of medical documents limited to desktop level will become the bottleneck to promote the application of electronic medical records and cannot solve real-time electronicization. The implementation of medical orders, vital signs entry and other issues, the application of Motorola mobile clinical information system allows medical staff to access electronic medical records anytime, anywhere, timely record patient-related information and obtain complete medical information. â–¡ Strengthen the efficiency and strength of hospital management. The mobile clinical information system uses efficient, real-time and mobile information processing methods to record the medical information, medical treatment and charging process of each link of the hospital in real time, which is convenient for hospital administrators to grasp all the hospital information in a timely and accurate manner Therefore, the management can make real-time decision-making and judgment according to the situation, improve the hospital assessment system, and improve the hospital management efficiency and management intensity.
(2) Reduce medical errors and accidents
Using one or two-dimensional bar code automatic identification technology, marking and identifying information such as drugs, biochemical specimens, equipment, medical staff and patient identities, the use of MC55 for bar code scanning can not only quickly confirm the correspondence between information, but also effectively eliminate Manually determine the occurrence of errors.
(3) Reduce the work intensity of medical staff and improve the efficiency of medical staff
The application of MC55 enables medical staff to obtain and process patient diagnosis and treatment information anytime, anywhere, which greatly reduces the work intensity and work pressure of medical staff, and also improves the work efficiency of medical staff in an all-round way.
(4) Optimize information access process
With the help of various mature technologies such as bar codes and mobile computing, it greatly reduces the work of mass information entry and manual copying in medical care.
(5) Realize the hospital management concept of "patient-centered"
Through the use of medical staff, real-time acquisition and processing of patient's diagnosis and treatment information is realized, ensuring that patients can get proper diagnosis and treatment in the first time.
2.2 Technical advantages
The mobile clinical information system is directly oriented to the first-line medical staff in the hospital information system, so it is necessary to ensure the advancement, practicability, reliability and safety of the selected technology. The overall construction of the system mainly meets the actual needs through the following advanced technologies.
2.2.1 Mobile computing and EDA technology
Mobile computing technology uses intelligent computing terminal equipment to solve the seamless access of different networks in a wireless environment, realize mobile computing, data transmission and resource sharing, and provide timely and accurate information to any user at any time and any place.
In order to meet the needs of mobility and portability in practical applications, Motorola combined with mobile computing, wireless calling, VOIP, barcode scanning and imaging technologies to launch EDA (Enterprise Digital Assistant) enterprise digital, which has more functions and advantages than traditional mobile computing devices Assistant, mobile data terminal EDA with enterprise-level application operation performance not only has the functions of traditional mobile computing devices, but also supports one or two-dimensional barcode label information collection, flexible voice and data communication, and convenient wireless local area network (WLAN) ) Synchronization and other functions. In terms of structural design, it is not only small and light, but also has the characteristics of waterproof, dustproof and anti-fall, which can withstand the rigorous test of daily use in a variety of environments.
2.2.2 Wireless LAN technology
The core advantage brought by wireless network technology is mobility. The information of medical institutions is very large. The application of wireless networks in medical institutions can meet the needs of establishing a "people-oriented" medical model. The particularity of the hospital application requires that the provided wireless LAN not only meet the functions of ordinary coverage and simple access, but also require the functions of seamless roaming throughout the building and comprehensive security access guarantee. Motorola, as a world-class provider of WLAN switching solutions, is committed to mobile application solutions and is one of the founding companies of the 802.11 series of wireless network protocols.
