碩士 === 中原大學 === 醫學工程學系 === 87 === The goal of thesis is to establish a emergency medical service system, which can be used in the ambulance or any stable sites without interference by the landforms or buildings. For the increasing demand with emergency medicine, the advanced communication and computer technologies were used to improve the telemedicine system which can avoid the time delay of saving patients, reduce the cost of curing and promote the quality of medicine. The cable network communication technology has been used in the telemedicine system, however, few disadvantages such as: the difficulty of cable mounting, low mobility, and high cost need to be solved in those systems. The system can be divide into three parts: the data transmission system of the transmit site, the monitor system of the receive site, and the case report database system. The communication mediums are the GSM mobile phone and the wireless local area network (LAN) equipment. The transmission information included different combinations of immediate biosignals, the still image, texts and speech. The communication protocol is TCP/IP and the communication interface program is written with the Winsock. The Paradox and the Sybase structure query language (SQL) Server were used as the database system and a database combination system was built to simulate the data processing and the medical case report database. The Borland Database Engine (BDE) is adopted in this system as the database combination interface, and the standard SQL language is used to do the data accessing. Some tests which including the influence of the movement of the mobile phone to the transmission speed, the transmission effects, the transmission reliable degree, the convenience and the expanding possibility and the electromagnetic noise factor, were used to evaluate the performance of this system. The results show that the movement of mobile phone is up to 100 km/hr or across to the station, the transmission speed is still not influenced. Transmission delays of the mobile phone and the wireless LAN equipment are within 3 seconds and 1 second, respectively. The transmission reliable degree of the biosignals, texts and images is 100%, and the quality of the transmission speech is also very clear. The equipment of this system is handy and convenient to carry and use. Moreover, the expanding and transposing possibility of the hardware and the software are good. There is no interference between this system and other wireless communication system. A emergency medical service system which have overcame the disadvantages of the inherent microwave antenna system was established. This wireless system can break the limitation of the old wire system. This system uses the inherent medical database in the laboratory and imitates to combine with the real medical information system. In the future, we hope this system can have some contribution in improving the emergency medical service system, promoting the medicine quality and endure the cost of the medicine after some improvements.
