Hospital Remote Terminal Development In Prehospital Emergency System

Prehospital emergency is very important for sudden illness. Because it makes patients physiological condition better for medical treatment when they arrive at the hospital, and give them more opportunities to obtain the life. This paper is based on prehospital emergency system for background. The system is composed of the following parts, such as Mobile Locator for Help, Ambulance Terminal, Emergency Monitoring Center and Hospital Remote Terminal. Patient's call for help promptly and ambulance's reach timely is necessary in the emergency case, but the most important thing is physiological data real-time transmission for doctors to remote medical treat.The Hospital Remote Terminal in this paper is able to display the first-aid information and the physiological data in real time for remote medical treat. Firstly, the paper introduced the design and the communication of every part of the system. Secondly, it describes the mainboard of the Hospital Remote Terminal and implemented it. And then, it also introduced the transplant process of the embedded operating system Windows CE. At the meantime, it finished the base function of software, including the control of the first-aid process, the method of GPRS dial-up, the design of Socket communication module based on TCP, the design of protocol analysis module, and the display mothod of the the patients' basic information and physical data in real time. Finally, the whole system was tested and evaluated, and also made the summary and prospected.
