Blood pressure information measurement apparatus cuff and blood pressure information measurement apparatus

Abstract

A blood pressure information measurement cuff includes a band-shaped cuff body and a fluid bladder that is connected to the cuff body and is configured to expand/contract with insertion or discharge of a fluid, the blood pressuring information measurement cuff being configured to be used while wrapped around a body being examined. The fluid bladder is formed into a rectangular bag shape by flattening a tube-shaped resin sheet and sealing the two end portions thereof that form openings. A partial welded portion, which is formed by the resin sheet being folded so as to overlap itself and welded, is formed on at least a portion of one of a pair of opposing sides that intersect the sides of the two sealed end portions and extend in a wrapping direction on the body being examined.
