At present, Chinas medical institution at the time of infusion therapy, infusion speed control is the use of artificial parties. Routine clinical transfusion, infusion bottle hanging widely used, and direct observation with your eyes, relying on clips to control the infusion speed manual, this mode of operation can not precisely control the speed of infusion, and the large amount of work. Therefore, we need cheap and practical inspection and monitoring of medical infusion devices to meet todays health care needs. The system design is based on AT89C51 microcontroller as the core to keyboard and optical sensor system as input to digital control and the motor output system of intelligent infusion as a control and monitoring system. Keyboard keys for the stand-alone system, the function of photoelectric sensors the speed of the liquid drip infusion bottle and reliable detection of page height. When the liquid amount is less than the warning value, alert systems, and you can manually remove the alert. Large motors have speed control and input p
