基于红外技术的输液点滴速度监控装置的设计

Design of a Transfusion Speed Monitor Based on Infrared Technology

设计了一种利用红外光的脉宽调制信号来采集输液信息的医用微量输液装置。该装置通过对液滴和液面的监测和控制,可以实现输液过程中滴速、输液容量的自动控制和测量,并提供声光报警和远程通信报警功能。经实验证明,具有安全、操作方便、参数可设定、抗干扰能力强、可靠性高、能够精确控制输液速度和输液总量等特点。

A transfusion speed monitor system is designed based on infrared technology with modulation and demodulation. With monitoring the drops and the liquid surface, the system can control the process of transfusion and give a sound-light alarm automatically. Through the experiment, it demonstrates that the monitor has the merits of accurate counting, reliable function, low cost, small volume; low power dissipation and easy handling.
