摘要：

To provide a pulse wave analysis apparatus capable of suppressing inaccuracy in detecting pulse waves caused by the nonlinearity of the change of the pressure/volume of blood vessels and more accurately acquiring the amplitude of an ejection waves and a reflection wave of the pulse waves.

SOLUTION: In the pulse wave analysis apparatus and a pressure control part 8 of a vascular internal/external pressure difference control part 2 controls the difference between the internal pressure and external pressure in the blood vessels in one region so that the amplitude of the pulse waves detected by a pulse wave amplitude information detecting part 7 is in a range in which the relation with the difference between the internal pressure and external pressure in the one region detected by a pulse wave detecting part 1 can be considered approximately as linear by controlling the external pressure applied to the blood vessels in the one region detected by the pulse wave detection part 1. As a result, the variation in the amplitude of the pulse waves relative to the variation of the internal pressure of the blood vessels can be linear and large and the amplitude of the ejection wave and reflection wave of the pulse waves can be more accurately detected by a pulse wave amplitude detection part 6.
