摘要
本文讨论了利用激光多普勒原理检测输液器中液体在输液管中的流速,并通过智能芯片对流速的监测,完成输液过程中对堵塞、流速过快、过漫、液体流空等现象进行报警。
Basing on the princiles of laser Doppler, the authors design a system to test the current velocity of liquid in the liquid pipeline. By using intelligent chip to test the current velocity, an alarm is given due to blocking up, liquid out, liquid flowing too fast, liquid flowing the slowly during perfusion.
