In present medical practice, infusion is an important and widely adopted treatment method. During the infusion process, the dripping speed of infusion is a significant parameter. In this paper, an intelligent infusion system is introduced, which is provided with dripping speed remote setting and abnormal situation alarm function. Through the application of fuzzy-PID control with auto-adjusted factors, the control of dripping speed is achieved. ZigBee and Wi-Fi construct a wireless network, therefore medical staff can set the dripping speed by making use of mobile terminals and meanwhile, the dripping speed is displayed on mobile terminals for nurses' reference. The test results indicate the following characteristics of the intelligent infusion system, such as fast response and high accuracy. Besides, the results also prove that the intelligent infusion system achieves the objective of reducing medical staff’s workload and improving patients’ safety.
