ARTERIOSCLEROSIS EVALUATING APPARATUS
First Claim
1. An arteriosclerosis evaluating apparatus comprising:
- a pulse wave detection device adapted to detect a pulse wave transmitted through an artery at one point of a living body;
a breakdown device adapted to perform fitting of the pulse wave detected by the pulse wave detection device with a fitting function to break down the pulse wave into a plurality of developed waves; and
an evaluation device adapted to evaluate a degree of arteriosclerosis from amplitude intensities of the developed waves broken down from the pulse wave.

Abstract
The disclosed is an arteriosclerosis evaluating apparatus capable of easily separating pulse wave data detected at one measurement site into an incident wave and a reflected wave and capable of easily determining and evaluating the degree of arteriosclerosis. The pulse wave transmitted through an artery is detected at one site of a living body by a pulse wave detection device, and the detected pulse wave is fitted with a fitting function by a breakdown device so that the detected pulse wave can be broken down into an incident wave and a reflected wave. The degree of arteriosclerosis is evaluated from the amplitude intensities (i.e., peak intensities) of the incident wave and the reflected wave broken down from the pulse wave.
