This paper presents a hospital intravenous infusion monitoring system based on a single-chip microcontroller. With the advancement of medical technology, the demand for high-precision treatment methods has become increasingly prominent, leading to the emergence of various hospital intravenous infusion monitoring systems to meet this demand. The system incorporates multiple functionalities: Firstly, it employs a liquid level detection module to monitor the liquid level in the infusion bottle. When the liquid is depleted during infusion, the system triggers an audio and visual alarm. Secondly, by utilizing infrared emitter-receiver pairs, the system monitors the fluid flow rate. Based on preset threshold values, the system controls the rotation direction of a stepper motor to adjust the compression of the infusion tube, thus maintaining an appropriate flow rate. A color sensor is employed to detect retrograde blood flow, and the system activates an alarm upon detection. The system also provides key setting and display functions. Healthcare providers can set flow rate thresholds and switch infusion states using buttons, while real-time measurement data can be viewed on the display screen. Additionally, a Bluetooth module enables wireless communication to transmit alarm messages indicating infusion bottle depletion or retrograde blood flow incidents, along with the current flow rate. Leveraging single-chip microcontroller technology, coupled with infrared emitter-receiver pairs, sensors, and wireless communication devices, this system enhances traditional intravenous infusion equipment. This innovation not only enhances patient drug absorption efficiency but also reduces the workload of medical staff and the likelihood of medical accidents during intravenous infusion. In comparison to other infusion monitoring systems, this system offers advantages such as stable operation, reliable performance, low cost, and the ability to meet clinical requirements, thus displaying strong feasibility for practical applications.
