Abstract
A low-cost disposable tourniquet cuff includes: a first sheet formed of flexible material that is impermeable to gas; a second sheet facing the first sheet and formed of flexible material impermeable to gas; a bladder seal joining the first sheet to the second sheet around a perimeter to form an inflatable bladder within the perimeter; port means communicating pneumatically with the bladder and releasably connectable to a tourniquet instrument; stiffener means contained within the inflatable bladder and formed of gas-impermeable material less flexible than the first sheet, wherein the stiffener means has a stiffener width dimension less than the bladder width dimension and is joined to the first sheet to form a non-inflatable portion of the first sheet; and securing means attached to the non-inflatable portion of the first sheet and adapted to allow a surgical user to releasably secure the cuff around the limb at the desired location so that the bladder overlaps upon itself.
