基于蓝牙的无线输液报警系统设计及应用解析

The graduation design project "Wireless Infusion Alarm System Based on Bluetooth" aims to address the challenges faced by healthcare professionals in managing intravenous infusions in hospitals. Due to the unpredictable nature of patient conditions and the high influx of patients during peak hours, healthcare workers often struggle to monitor and stop infusions in a timely manner, which can lead to serious consequences for patients. The design of this system involves a master-slave setup where a main unit communicates with multiple infusion monitoring devices through Bluetooth technology. The system utilizes photoelectric sensors to detect changes in the liquid level within the infusion tube, and the detected signals are processed by a microcontroller to determine if the infusion is complete. In case of completion, an alarm signal is generated and sent wirelessly via Bluetooth to the alarm terminal, resulting in a dual-level alarm system (master alarm unit and slave infusion monitoring unit). The use of Bluetooth technology enables centralized management of multiple infusion monitoring devices by a single master alarm unit, providing flexibility for healthcare workers to move the monitoring devices within the effective Bluetooth signal range. This system effectively addresses the challenges in infusion management, alleviating the workload and stress on healthcare professionals and mitigating the issues arising from the shortage of healthcare staff in hospitals.
