Sphygmomanometer cuff capable of blocking blood flow favorably even with small width in wrapping direction

摘要

A bladder incorporated in a cuff includes an outer wall located at the outer side, an inner wall located at the inner side, side walls connected to both side ends of the outer wall and the inner wall in the wrapping direction, and folded inward of the bladder, and a joint connecting the side walls inside the bladder. A sphygmomanometer cuff is provided that can maintain the former configuration even when inflated or deflated without change in the width even if the bladder is inflated, and that does not dilate in the width direction when inflated.
