Abstract

A velocimeter for measurements of blood flow velocity in microvessels was constructed with a microscope, a grating, a photomultiplier and a wave-period measuring circuit. A differential detection system seemed to be useful when the probing area was extremely small. A pulsating flow velocity contour and the velocity reduction caused by an application of noradrenaline were on-line recorded in an arteriole of foot web of frogs.

摘要

利用显微镜、光栅、光电倍增管和波周期测量电路构建了一种用于测量微血管中血流速度的测速仪。当探测区域极其小时，差分检测系统似乎很有用。在青蛙蹼的小动脉中在线记录了脉动血流速度轮廓以及去甲肾上腺素应用引起的速度降低。
