Abstract

A blood pressure measurement cuff is worn on a measurement site that extends in longitudinal direction in substantial round bar shape and gradually becomes thinner from one side to another side in longitudinal direction. A band-shaped body is included which is configured to contain an air bladder between an inner cloth that is to come into contact with the measurement site and an outer cloth that opposes the inner cloth, the band-shaped body being configured to be wrapped in a circumferential direction around the measurement site. A plate member is included which is provided between the outer cloth and the air bladder in a thickness direction and in a region that corresponds to at least a portion in the circumferential direction of the band-shaped body. The thickness of the plate member gradually becomes thinner from the one side to the other side in the longitudinal direction.

First claim

1 . A blood pressure measurement cuff to be worn on a measurement site that extends in a longitudinal direction substantially in a round bar shape and gradually becomes thinner from one side to another side in the longitudinal direction, comprising:
a band-shaped body configured to contain an air bladder between an inner cloth that is to come into contact with the measurement site and an outer cloth that opposes the inner cloth, the band-shaped body being configured to be wrapped in a circumferential direction around the measurement site; and a plate member provided between the outer cloth and the air bladder in a thickness direction and in a region that corresponds to at least a portion in the circumferential direction of the band-shaped body, wherein the thickness of the plate-shaped member gradually becomes thinner from the one side to the other side in an entire region of the plate member along the longitudinal direction.

2 . The blood pressure measurement cuff according to claim 1 , wherein
a degree to which the thickness of the plate member gradually becomes thinner from the one side to the other side in the longitudinal direction is set according to a degree to which the measurement site gradually becomes thinner from the one side to the other side in the longitudinal direction.

3 . The blood pressure measurement cuff according to claim 1 , wherein
the measurement site is a wrist, and the plate member is provided so as to oppose only a region corresponding to a palm of a hand or a back of a hand in a circumference of the wrist.

4 . The blood pressure measurement cuff according to claim 3 , wherein
the plate member curves with a curvature radius that conforms to an outer circumferential surface of the region corresponding to the palm of the hand or the region corresponding to the back of the hand in the circumferential direction.

5 . The blood pressure measurement cuff according to claim 1 , wherein
the plate member is flat in the circumferential direction.

6 . The blood pressure measurement cuff according to claim 1 , wherein
a circumferential direction dimension of the plate member is constant from an end on the one side to an end on the other side in the longitudinal direction.

7 . The blood pressure measurement cuff according to claim 1 , wherein
a circumferential direction dimension of the plate member gradually decreases from the one side to the other side in the longitudinal direction.

8 . The blood pressure measurement cuff according to claim 1 , wherein
the plate member is composed of a material having elasticity.

9 . A blood pressure monitor, comprising:
the blood pressure measurement cuff according to claim 1 ; and a main body equipped with an element for blood pressure measurement.

10 . The blood pressure monitor according to claim 9 , wherein
the plate member of the cuff includes an element for coupling and integrating the cuff and the main body.
