Abstract

A blood pressure measurement device enabling an increase in joining strength between a cuff and a junction target preventing an increase in size of the blood pressure measurement device. The device includes a case including an outer case having a tubular shape, a curler curving in such a manner as to follow along a circumferential direction of a portion of the wrist where the blood pressure measurement device is attached, the curler including a first facing portion aligned at one end of the outer case in a thickness direction, and a back-side cuff formed of two sheets formed of a resin material, the back-side cuff being configured to be inflated with a fluid, one of the sheet members that is disposed on the curler side including a second facing portion facing the first facing portion, and the second facing portion being larger than other portions of the back-side cuff.

First claim

1 . A blood pressure measurement device comprising:
a case including an outer case having a tubular shape; a curler curving in such a manner as to follow along a circumferential direction of a portion of a living body where the blood pressure measurement device is attached, the curler including a first facing portion aligned at one end of the outer case in a thickness direction; and a cuff formed of two sheet members formed of a resin material, the cuff being configured to be inflated with a fluid, one of the sheet members that is disposed on the curler side including a second facing portion facing the first facing portion, and the second facing portion being larger than other portions of the cuff in a width direction.

2 . The blood pressure measurement device according to claim 1 , wherein the first facing portion is constituted in a shape being larger than other portions of the curler in a width direction.

3 . The blood pressure measurement device according to claim 2 , further comprising a cover member sandwiching a portion of the second facing portion between the cover member and the first facing portion, the portion protruding beyond the other portions in the width direction.

4 . The blood pressure measurement device according to claim 3 , wherein
the cover member includes a protruding portion, the second facing portion includes a hole where a part of the protruding portion is disposed, and the first facing portion includes a fitting portion where a part of the protruding portion fits.

5 . The blood pressure measurement device according to claim 1 , wherein
the case includes a back lid covering the one end of the outer case, and the first facing portion is connected to the back lid.

6 . The blood pressure measurement device according to claim 2 , wherein the first facing portion covers the one end of the outer case.
