人体输液智能监测系统的设计与实现
摘要
随着医疗技术的不断进步和人们对健康管理的日益重视，人体输液智能监测系统的需求愈发迫切。为此，本文设计并实现了一款基于STM32F103C8T6单片机的便携式人体输液智能监测系统。
该系统集成了多个功能模块，包括液位检测、颜色传感器和红外对管，用于实时监测输液瓶的液体剩余量、检测回血现象和调整液体流速。通过心率血氧检测模块实时监测患者生理参数，一旦检测到异常情况，如液体耗尽、回血或心率血氧异常，系统会通过声光报警提醒医护人员，并自动关闭输液开关。系统还支持通过按键设置和调节流速，并通过OLED显示屏实时显示测量数据。此外，具备蓝牙通信功能，可将数据发送至手机端，实现远程监控和控制，提高输液过程的智能化和便捷性。
该系统的设计与实现，不仅提升了人体输液监测的效率和准确性，也为便携式人体输液智能监测系统的进一步优化和升级提供了有益的探索，具有广泛的应用前景。

Abstract
With the continuous advancement of medical technology and the increasing emphasis on health management, the demand for intelligent monitoring systems for human infusion has become increasingly urgent. Therefore, this article designs and implements a portable human infusion intelligent monitoring system based on STM32F103C8T6 microcontroller.
The system integrates multiple functional modules, including liquid level detection, color sensors, and infrared tubing, for real-time monitoring of the remaining liquid level in infusion bottles, detecting blood reflux phenomena, and adjusting liquid flow rate. Real time monitoring of patient physiological parameters through the heart rate and blood oxygen detection module. Once abnormal conditions are detected, such as fluid depletion, blood return, or abnormal heart rate and blood oxygen, the system will alert medical staff through sound and light alarms and automatically turn off the infusion switch. The system also supports setting and adjusting flow rate through buttons, and displaying measurement data in real-time through an OLED display screen. In addition, it has Bluetooth communication function, which can send data to the mobile phone for remote monitoring and control, improving the intelligence and convenience of the infusion process.
The design and implementation of this system not only improves the efficiency and accuracy of human infusion monitoring, but also provides useful exploration for further optimization and upgrading of portable human infusion intelligent monitoring systems, with broad application prospects.
