Single-bladder cuffs intended for reuse including an inflatable bladder and a contoured cuff that has a smaller diameter distally than proximally when wrapped. 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 one 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. Contoured cuffs have an arced design to give them the smaller distal diameter when wrapped; some cuffs include pivoting fastening straps to allow adjustment of both distal and proximal diameters to suit the limb which also provides more comfort to patients. Reusable single-bladder contoured cuffs may be washed and/or sterilized after each use; some of the components of the cuff (e.g., bladder, sleeve) may be replaced. They are used mainly during surgical procedures in the extremities using general anesthesia. Reusable contoured single-bladder cuffs intended for use in specific extremity areas (e.g., arm, thigh, wrist, ankle) are also available.
