摘要：
A disposable tourniquet cuff for encircling a patients limb includes first and second sheets a gas-tight peripheral seal joining the first sheet to the second sheet around a perimeter of those sheets to form an inflatable bladder within the perimeter. A stiffener fits inside the bladder and is sized to extend substantially the length of the bladder and to fit completely within the peripheral seal. The stiffener is separate from the second sheet and the stiffener surface is welded to the first sheet at a location within the bladder and away from the peripheral seal. A tubular port is provided for directing gas into the bladder from a tourniquet instrument to which the port may be connected. The port defines a passageway therethrough and includes a flange made of a thermoplastic polymer that is compatible for welding the flange to the first sheet.
