一种低功耗无人值守输液监控系统的研制

Development of a New Unmanned Low-power Infusion Monitoring System

目的:设计一种新型的低功耗、无人值守输液监控器。方法:以超低功耗单片机MSP430作为主监控器的控制核心,运用称重传感器完成对输液状态的监测。结果:主监控器可实时监测输液状态,并可在位于护士站的上位机上显示监测状态。结论:系统的功耗与成本低,性能稳定,易于携带,实用性强。

Objective To design a new unmanned low-power,portable infusion monitoring system. Methods We considered a low-power MCU MSP430 as the main core of the controller and used the weighing sensor to monitor fluid status. Results The system can display the status at the infusion monitoring systems and host computer of nurse-stations. Conclusion The development of this system reduces power consumption,cost and improves the system stability and practicality.[Chinese Medical Equipment Journal ,2009,30（9） ：11-13]
