Double-bladder cuffs intended for a single-use (i.e., disposable), including two inflatable bladders and a standard (typically cylindrical) 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 two small bladders within the cuff that are 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. Disposable double-bladder standard cuffs are usually supplied sterile in individual pouches for only one use and are not intended for sterilization processes at the healthcare facility. They are usually made of one integral unit in which components (e.g., bladders) cannot be replaced. Disposable standard double-bladder cuffs intended for use in specific extremity areas (e.g., arm, thigh, wrist, ankle) are available. Dedicated disposable non-standard cuffs with a smaller diameter distally than proximally when wrapped (i.e., contoured cuffs) are also available.
