Cuffs including an inflatable bladder and a regular (typically cylindrical or rectangular), non-tapered (i.e., standard) shape, that are designed to exert a pressure on the circumference of an extremity by means of a compressed gas delivered by a pneumatic tourniquet. These devices usually include one small bladder within the cuff that is inflated through tubes (e.g., hoses) that run from the bladder connectors to the source of compressed air located in the control unit of the tourniquet. The cuff is fastened to the extremity using contact mechanisms (e.g., clips) and frequently secured with an external ribbon. Single-bladder standard cuffs (both reusable and disposable) are used mainly during surgical procedures in the extremities using general anesthesia which enable surgeons to perform delicate procedures in bloodless operative fields. Standard single-bladder cuffs (both reusable and disposable) intended for use in specific extremity areas (e.g., arm, thigh, wrist, ankle) are available. Dedicated non-standard cuffs with a smaller diameter distally than proximal when wrapped (i.e., contoured cuffs) are also available.
