発明の名称 (英語) FINGER ARTERIOLAR DILATABILITY TESTING METHOD, FINGER ARTERIOLAR DILATABILITY TESTING DEVICE, AND FINGER ARTERIOLAR DILATABILITY TESTING PROGRAM コモンズ 新技術説明会
発明の概要(英語) [Problem] To provide a finger arteriolar dilatability testing method, finger arteriolar dilatability testing device, and finger arteriolar dilatability testing program with which it is possible to simply test for early signs of arteriosclerosis using the microvessels of the finger arteries. [Solution] In the present invention, the following are provided: a pulse wave data storage step for storing the resting pulse wave data and the reperfusion pulse wave data after removing a tourniquet from one forearm, for the arteries of each finger of both hands which are pressed using a predetermined sequence; an NPV calculation step for calculating, on the basis of the pulse wave data stored in the pulse wave data storage step, an NPV for each heartbeat, where the NPV is obtained by dividing the amplitude of the alternating current component of the pulse wave by the average direct current component value of each pulse wave; a pulse pressure data acquisition step for acquiring the pulse pressure which is obtained by subtracting the minimum blood pressure from the maximum blood pressure; and an FCR ratio calculation step for calculating, on the basis of the pulse pressure acquired by the pulse pressure data acquisition step, for each heartbeat the index (FCR ratio) that shows the vasodilation reaction of the finger arteries.
