Abstract：To address the limitations of conventional hospital infusion systems,such as air ingress into tubing and the requirement for continuous manual supervision,this study develops an intelligent infusion monitoring system based on a single-chip microcomputer.The system integrates multi-functional capabilities,including real-time liquid level sensing,automated alarm triggering upon infusion completion,Bluetooth-enabled data transmission,precision flow rate regulation,parameter display,blood backflow prevention,and button-based operational control.Comprehensive evaluations were performed on droplet visualization,anti-reflux functionality,flow rate measurement,and closed-loop regulation.Experimental results validate that the system can stably maintain target infusion rates and accurately detect droplet dynamics,ensuring the safety and reliability of intravenous therapy while facilitating centralized management for healthcare providers.
