Methods Through the infrared transmitter and receiver circuit and image sensor acquisition circuit, the infusion speed and volume were monitored by the singlechip, thus the flow rate of infusion was controlled accurately. Main circuits also included key input circuit, LCD circuits, alarm circuits and so on, and thus the desired flow rate and monitor surplus could be input. Resulte After practical testing, the infusion monitor and control system could accurately monitor and control the infusion pump. Conchsion The system, with easy operation, high accuracy and reliability, is worth popularization.
