The design of a transfusion monitoring system based on ZigBee wireless communication technology, which effectively solve the problems as follow, intravenous infusion rate existing in the process is difficult to control, no alarm for infusion interrupt, infusion is completed silently and other issues. Using infrared photoelectric sensor for real-time monitoring of the infusion process, such as droplet velocity, information of liquid level and infusion volume, and feedback the information via ZigBee wireless networks to the host machine. Medical staff at the nursing station can keep track of the information of entire hospital infusion through a visualization software platform, timely and effective manner to deal with emergencies. Implementation results show that:the system liquid drip detection accuracy, the error at ±2 drops, when the liquid level is lowered a certain amount or infusion abnormal situation occur, the terminal nodes can audible alarm, PC software issued an orange or red alert message, effectively improve transfusion safety and reduce medical errors.
