Abstract

Provide is a wrist type blood pressure meter cuff not oppressing the non-selected artery so as to prevent its pulse waves from mixing into pulse waves of the selected artery necessary for measurement, in a cuff used in a blood pressure meter for measuring blood pressures by selecting and oppressing one artery of the wrist. A wrist type blood pressure meter cuff comprises a fluid bag for oppressing a selected artery of either radial artery or ulnar artery located at the wrist by feeding fluid inside to inflate, and a fixing member for fixing the fluid bag at the wrist. By forming a gap between the fixing member and the wrist, the oppressing pressure directly applied from the fixing member to the wrist at which the non-selected artery is located is set smaller than the oppressing pressure directly applied from the fixing member to other position of the wrist when oppressing the wrist by inflating the fluid bag. This gap is produced by a swollen part provided in the fixing member.

Claims

1. A wrist type blood pressure meter cuff comprising a fluid bag for oppressing a selected artery of either radial artery or ulnar artery located at the wrist by feeding fluid inside to inflate, and a fixing member for fixing the fluid bag at the wrist,

wherein the fixing member has a structure so that the oppressing pressure directly applied from the fixing member to the wrist at which the non-selected artery is located may be smaller than the oppressing pressure directly applied from the fixing member to other position of the wrist when oppressing the wrist by inflating the fluid bag.

2. The wrist type blood pressure meter cuff according to claim 1, wherein the fixing member has a shape so as to form a gap at least in part of the wrist surface at which the non-selected artery is located, when the wrist type blood pressure meter cuff is fixed at the wrist in a contracted state of the fluid bag.

3. The wrist type blood pressure meter cuff according to claim 2, wherein the fixing member includes a swollen part of at least part of inner surface of the position coinciding with the non-selected artery swollen in the outward direction.

4. The wrist type blood pressure meter cuff according to claim 2, wherein the fixing member includes a spacer abutting against the wrist, and the gap is formed by this spacer.

5. The wrist type blood pressure meter cuff according to claim 4, wherein the spacer has a shape of which inner surface is curved along the bone of the wrist.

6. The wrist type blood pressure meter cuff according to claim 1, wherein the fixing member has a structure so that the rate of area of direct contact of the fixing member at the wrist at which the non-selected artery is located is smaller than the rate of area of direct contact of the fixing member in other position of the wrist.

7. The wrist type blood pressure meter cuff according to claim 6, where in the fixing member has an opening in the position coinciding with the non-selected artery.

8. The wrist type blood pressure meter cuff according to claim 6, wherein the fixing member includes a discontinuous part in the position coinciding with the non-selected artery of the fixing member to compose a fixing member main body, and the discontinuous part is coupled by a coupling member of which width in the longitudinal direction of artery is narrower than the fixing member main body.
