Abstract
A sheet member is to form a bladder. A tubular member is to form a ventilation channel communicating with the bladder. A welded portion at which the sheet member and the tubular member are welded extends along a longitudinal direction of the tubular member over an entire circumference of the tubular member.
Claims7
A cuff adapted to be used for blood pressure measurement comprising:
- a sheet member forming a bladder;
- a tubular member forming a ventilation channel communicating with the bladder;
- and
- a welded portion at which the sheet member is welded to an outer circumferential surface of the tubular member,
- wherein the welded portion extends along a longitudinal direction of the tubular member over an entire circumference of the tubular member,
- wherein a dimension of the welded portion along the longitudinal direction of the tubular member is larger than a dimension of the welded portion along a radial direction of the tubular member;
- and
- wherein an inner surface of the sheet member is curved toward an end of the tubular member in the longitudinal direction of the outer circumferential surface that is closer to the bladder, and the inner surface of the sheet member is curved toward an exterior of the bladder.
