In order to monitor the process of intravenous transfusion of the patient scientifically and effectively, the monitoring system for transfusion based on the technology of Zigbee is researched and designed. Labview is used to design PC monitor interface. Groove type optoelectronic switch is used to detect dripping speed. Wireless transmission module is used to send and receive data. A new kind of electronic clip is designed to control the cross sectional area of the dropper by adjusting the stepping motor, which controls opening size of the electronic clip, so that it can achieve the purpose of controlling dripping speed. Proved by experiments the system works stably, it not only realizes the function of remote monitoring in the process of transfusion, but also meets the requirements of controlling dripping speed.
