Abstract
A disposable inflatable tourniquet apparatus includes an inner inflatable bladder formed of two rectangular bladder wall members of polymer impregnated fabric peripherally welded to form a peripheral bond that develops the burst pressure of the bladder wall members. A conduit inflates the bladder, and a fabric cover is peripherally stitched at a border to the bladder at the peripheral bond. A curved stiffener plate is held inside the cover but outside the bladder, and within the stitched border.
