Arteriosclerosis-degree evaluating apparatus
First Claim
1. An apparatus for evaluating a degree of arteriosclerosis of a living subject, comprising:
- a pulse-wave detecting device adapted to be worn on a first portion of the living subject having a first pressing bag adapted to be wound around the first portion of the subject and a second pressing bag adapted to be worn on a second portion of the subject located on a distal side of the first portion, the first and second pressing bags being connected integrally to each other by a connecting member such that the first and second pressing bags are spaced apart from each other;
a pressing device adapted to be worn on the second portion of the subject, for pressing the second portion so as to stop a flow of blood at the second portion; and
an arteriosclerosis-related information obtaining means for obtaining arteriosclerosis-related information used for evaluating said degree of arteriosclerosis of the subject, based on a peak point of an incident-wave component, and a peak point of a reflected-wave component, of a pulse of a pulse wave that is detected by the pulse-wave detecting device in a state in which the flow of blood is stopped by the pressing device.

Abstract
An apparatus for evaluating a degree of arteriosclerosis of a living subject, including: a pulse-wave detecting device adapted to be worn on a first portion of the living subject; a pressing device adapted to be worn on a second portion of the subject located on a distal side of the first portion, for pressing the second portion so as to restrict a flow of blood at the second portion; and an arteriosclerosis-related information obtaining device which obtains arteriosclerosis-related information used for evaluating said degree of arteriosclerosis of the subject, based on a peak point of an incident-wave component, and a peak point of a reflected-wave component, of a pulse of a pulse wave that is detected by the pulse-wave detecting device in a state in which the flow of blood is restricted by the pressing device.

a pulse-wave detecting device adapted to be worn on a first portion of the living subject;
a pressing device adapted to be worn on a second portion of the subject located on a distal side of the first portion, for pressing the second portion so as to restrict a flow of blood at the second portion;
an arteriosclerosis-related information obtaining means for obtaining arteriosclerosis-related information used for evaluating said degree of arteriosclerosis of the subject, based on a peak point of an incident-wave component, and a peak point of a reflected-wave component, of a pulse of pulse wave that is detected by the pulse-wave detecting device in a state in which the flow of blood is restricted by the pressing device; and
an incident-wave peak-point determining means for determining a time of occurrence of a peak point of an incident-wave component of a pulse of a pulse wave that is detected by the pulse-wave detecting device in a state in which the flow of blood is not restricted at the second portion by the pressing device. - View Dependent Claims (11)
