Patent ID: 6932773

Claim:
A wrist type blood pressure meter cuff comprising a fluid bag for compressing a selected artery of a radial artery or ulnar artery located at a wrist of a user by feeding fluid to the fluid bag to inflate the fluid bag, and a fixing member for fixing the fluid bag at the wrist, wherein the fixing member has a structure so that the compressing pressure directly applied from the fixing member to the wrist at which the non-selected artery is located may be smaller than the compressing pressure directly applied from the fixing member to another position of the wrist when compressing the wrist by inflating the fluid bags, wherein the fixing member has a shape so as to form a gap between the surface of the wrist at the location of the non-selected artery and a surface of the inner surface of the fixing member, when the wrist type blood pressure meter cuff is fixed at the wrist in a contracted state of the fluid bag and 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.
