Mobile medical terminals show four development trends

in recent years, the integration of medical business applications and network platforms is gradually becoming a new direction of medical information development. In the future, the development of medical information system will tend to the data fusion of various medical and health subsystems and the unified management of health record data center, so as to ensure the maximization of the utilization of medical and health resources

as an important display means of medical informatization, medical terminals have become the focus of research and development of relevant departments. With the continuous improvement of the degree of medical informatization, the types of medical terminals are becoming richer and the number is growing rapidly, and they are developing rapidly in the direction of mobility, miniaturization, networking and open interface

shortening the distance between doctors and patients is the key

in terms of the development of medical terminals, early medical terminals play an important role in the examination, treatment and diagnosis of diseases. Their main applications include hospital wards, ICU (emergency care center), physical examination centers, and some community medical service centers and other professional medical institutions

with the development of network technology and electronic technology, some medical terminals with new characteristics are widely used, such as digital auxiliary medical terminals, which can realize auxiliary diagnosis, biosensor diagnosis, robot equipment auxiliary diagnosis and other functions; The network medical terminal realizes the remote transmission of medical data; Family and community medical terminals make family self-monitoring and diagnosis a reality; Non traumatic and minimally invasive medical terminals have become an important direction for the development of medical terminals in the future

in terms of the current application of medical terminals in China, there are three types of terminals with wide application scope and good effect. For example, some hospitals in Wuxi City, Jiangsu Province use PDA with medical function, which can realize remote mobile consultation by sharing medical examination pictures, which greatly shortens the distance between doctors and patients. Not only that, the baby logo recognition function of the terminal can help the maternity and children's Hospital solve the problems of newborn baby identity recognition, infant wrong claim and theft by wearing RFID logo rings for infants. Specifically, medical PDA is designed and manufactured with EDA technology, built-in wireless local area and RFID identification equipment, and equipped with special software. Medical staff can use this terminal to interact with the hospital's his system or inpatient management system to view medical record information, write medical records, issue medical orders, record patient requirements, etc. in front of the hospital bed, and transmit them to the his database in real time

secondly, portable sign information monitoring terminals are also widely used in medical informatization. For example, the core of China Unicom's intelligent medical emergency monitoring system is to receive the data collected by the medical sensing terminal in real time, analyze, process and transmit it through portable ECG monitor, video and other sensing devices, and then transmit the video, physical signs and geographical location information to the background service system through GSM or WCDMA network, so as to facilitate the medical institutions to realize the comprehensive services of telemedicine emergency monitoring, diagnosis and consultation. Nowadays, the new portable ECG monitor can not only record short-term cardiac abnormal information anytime and anywhere, but also quickly transmit the collected physiological signals to the back-end service platform to realize stand-alone measurement, plug and play and other functions, which provides a fast communication channel for family, community doctors and expert doctors [measurement and display system] to collect samples by photoelectric encoder

moreover, connecting one or more medical monitors to the health management terminal through wired or wireless means can realize the simultaneous acquisition and storage of multi-channel biomedical signals. After the medical institutions use the built-in medical monitoring module for analysis and processing, they can display the measurement on the terminal screen and turn on the wire to change the results of the experimental machine. For example, the personal health management business provided by some health service providers now integrates the front-end health management terminal and the background management service. Users can monitor the sign information through the built-in or split sign detection and perception terminal of the terminal, and send the information to the corresponding health monitoring center through 3G network, so as to obtain personalized monitoring services anytime and anywhere Long term health record management services and regular health monitoring reports can effectively prevent diseases

at the technical level, we need to strengthen defense in depth

while a series of medical information terminals are widely used, we must also recognize some security problems and technical challenges

in the author's opinion, the first problem is data security. On the one hand, medical terminals are vulnerable to attacks, and terminal security is the weakness of the overall security of the digital medical system; On the other hand, because health data involves user privacy, relevant personnel should be cautious about data leakage and other issues. Therefore, we must realize defense in depth and design reliable encryption and decryption algorithm and key management mechanism

in addition, due to the large amount of data collected by medical terminals, medical data is very important for clinical diagnosis. In order to avoid being tampered with or eliminated without reason, it is necessary to establish a large storage capacity and reliable data transmission and storage mechanism to ensure the integrity and accuracy of data; Since the terminal equipment may exist in the coverage of other wireless networks, it should be ensured that it will not interfere with other networks, and it should also avoid interference from other networks; In the case of a large number of centralized medical terminals, in order to ensure real-time data transmission, medical institutions must solve the problems of how to avoid congestion and how to implement congestion control; Finally, in order to realize accurate mutual recognition and sharing of medical data between different terminals and avoid information closure and repeated investment, relevant institutions must formulate data exchange and sharing standards

at present, the process of medical informatization is changing the management and service mode of the medical industry. 4. Technical indicators: with the gradual maturity of various new technologies, the development of medical terminals will also have new changes. The author believes that in the future, medical information terminals will show the following trends: first, digitalization, medical terminals will realize collection, otherwise it is easy to cause the scraping operation and numbering of the material layer. Scraping mold is mainly to scrape off the excess information and digitalize the transmission information, so as to facilitate the later data utilization; Second, interface standardization. In order to reduce the data integration and comprehensive utilization of multi type and multi parameter medical terminals in the future, relevant departments need to standardize the interfaces of various medical terminals; Third, networking, the combination of medical terminal and communication module has become the realization method of some medical terminal products. On the one hand, it realizes the real-time remote transmission of medical data, on the other hand, it realizes the background remote control and intervention of medical terminal; Fourth, low cost. On the basis of ensuring the accuracy of medical monitoring data, reducing the cost of medical terminals and miniaturization have become the future development trend
