Wrist type blood pressure meter cuff

摘要

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 41 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 30 for fixing the fluid bag 41 at the wrist. By forming a gap between the fixing member 30 and the wrist, the oppressing pressure directly applied from the fixing member 30 to the wrist at which the non-selected artery is located is set smaller than the oppressing pressure directly applied from the fixing member 30 to other position of the wrist when oppressing the wrist by inflating the fluid bag 41. This gap is produced by a swollen part 33 provided in the fixing member 30.
