挠、尺动脉的无创血液流动阻力测量

The noninvasive measurement of the flowing resistence of blood on artery of the radial artery and of the ulnar artery

在肘部和腕部放置气袖,指尖放置脉搏传感器。同步放气,肘部达到收缩压时,腕部开始收到脉搏信号,腕部达到收缩压时,指尖收到脉搏信号。于是测出压降,近而得到阻力。

The air cell is placed on the ancon and wrist,pulse transducer is placed on fingertip.Deflating in-phase,when ancon get blood systolic pressures,pulse signal is received on the wrist.When wrist get the blood systolic pressures,pulse signal is received on the finger tip.So the pressure difference is measured,then the flowing resistence of blood is received.
