This unique Aircast Calf Cuff is the ideal treatment for when cooling and compression is needed. Ideal for calf-related acute sprains, trauma, post-op and rehabilitation as the cuff minimizes swelling and pain. The 10" long cuff is anatomically designed to completely fit the calf. Simply position the empty cuff on the calf with the quick-disconnect pointing down. Attach the cooler tube (not included), raise the cooler 15" above the cuff and let the cuff fill. Once full, the tube can be disconnected from the cuff so you can take cooling relief on the go. Please Note - This is the Aircast Calf Cuff only. Coolers are available separately. Compression of the cuff is gravity controlled. No outlets or electricity needed. Be advised, this cuff can reach and maintain temperatures cold enough to cause serious injury. Please read and understand all warnings and instructions for use before using this device. To clean, simply drain the water from the cuff. For the outside of the cuff, use warm water and a few ounces of liquid soap. Cuffs are made of nylon and vinyl and are Latex Free. The cuffs are designed for single-patient use only and should not be rotated among patients in multi-user environment.
