The Aircast Knee Cryo/Cuff with Gravity Cooler is an integrated approach to cold therapy that combines cold and focal compression delivered using a non-motorized, gravity-fed system. It delivers chilled water directly into a Cryo/Cuff that is anatomically designed to provide maximum cryotherapy, eliminating the risk of tissue damage. The Gravity Cooler holds water and ice needed to provide 6 to 8 hours of cryotherapy, and is compatible with all Cryo/Cuff and Arctic Flow pads. It's ideal for minimizing hemarthrosis, swelling, managing pain, post-operative recovery, trauma, rehabilitation and sports injuries. The Gravity Cooler includes tube assembly, plastic fittings and an insulation disk. The user manual provides easy to follow directions for use. Universal fit allows the Aircast Knee Cryo/Cuff to be worn on either the left or the right leg.
