Now, the intravenous infusion is used commonly as transfusion methods in hospital, most of the infusion′s speed is controled by health-care workers, and the temperature of the infusion liquid depends on the temperature of the environment. The health-care workers should inspect regularly to determine whether the infusion is over. This makes the health-care workers find it is difficuclt to deal with the accidents, for example, the infusion can not be stopped in time, the low-temperature reaction dues to the environmental temperature and the pharmacological reaction brought by the inaccurate control of the speed. The result is that the effect of the infusion is not satisfied, the patients suffers, and the result even caused medical accident in some case. So the medical infusion alarm, heater, monitor borns in this context.Based on the summing up and learning from the research results achieved by the scholars at home and abroad, with the actural requirements of subject, a infusion monitoring and control sysytem is designed after the discussion of every implementation. The system is based on the single-chip, used photoelectricity detection technology and motor control technology to realize the function. A big current control is also solved in this subject. The infusion system is composed of alarm module, temperature detection and control module, speed of infusion detection and control module, keyboard and display modules, power module. Some fuctions are achieved with the hardware design and software program, such as temperasture measurement, adjustment and display, count drops in scheduled time,display and control the speed, keyboard setting, liquid crystal display and so on. The design of the hardware circuit and the operating principle of each module are introduced in detail, some figures of the processes and software code are also provided in this paper. In order to realize the fuctions of each module, several mechanical implementation are designed to assure the signal acquisition of the system, so the stability and the whole system performance are enhanced, and the automatic monitoring of temperature, speed, alarm in the whole process are achieved finally. The system can be improved appropriated to be used in the field of blood infusion and this will have a broad applicatin prospect.
