Abstract:
1. An arteriostenosis inspecting apparatus, comprising: an inflatable cuff which is adapted to be worn on an ankle of a living subject; a cuff-pressure change device which decreases a pressure in the cuff from a pressure higher than a systolic blood pressure of the ankle; a distal-pulse-wave detecting device which is adapted to be worn on a distal portion of the subject that is located on a distal side of the anide and detects a distal pulse wave produced from the distal portion; an increasing-point detecting means for detecting at least one increasing point where a magnitude of the distal pulse wave continuously detected by the distal-pulse-wave detecting device when the pressure of the cuff is decreased by the cuff-pressure changing device, significantly increases; and an arteriostenosis judging means for judging that the subject has arteriostenosis, based on a fact that the increasing-point detecting means detects the second increasing point.
