Cuffs with a regular (typically cylindrical or rectangular), non-tapered (i.e., standard) shape. The cuffs 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 bladders\' 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. Each bladder may be inflated and deflated separately, improving safety and patient comfort. Double-bladder standard cuffs are used mainly during surgical procedures in the extremities using intravenous regional anesthesia enabling surgeons to perform delicate procedures in bloodless operative fields. Standard double-bladder cuffs (both reusable and disposable) intended for use in specific extremity areas (e.g., arm, thigh, wrist, ankle) are usually cylindrical in shape; standard cuffs with other shapes such as rectangular and conical are also available. Dedicated non-standard cuffs with a smaller diameter distally than proximally when wrapped (i.e., contoured cuffs) are also available.
