Design and Realization of Intelligent Infusion Monitoring System

This design is for the current medical infusion problems, designed a set of intelligent infusion monitoring system. It consists of STM32 microcontroller, TFT1.44-inch color LCD display circuit,servo driver circuit,infrared photoelectric drip rate detection circuit,non-contact capacitive level sensor circuit, buzzer alarm circuit, wireless Bluetooth module,key circuit and cell phone APP,etc.,and the corresponding software design is completed. The following four functions are realized by this system: (1) the drip rate of infusion and the volume of medicine can be set independently: (2) the current drip rate can be automatically controlled and the retention of the infusion bottle can be detected; (3) the cell phone APP can check the information of infusion; (4) the alarm information liquid system can be utilized to transmit data by using wireless Bluetooth.
