This is the whisper-quiet therapeutic device that continuously recirculates cold water in a controlled setting to help soothe pain and swelling. Cold therapy is a proven, non-invasive treatment to promote healing after surgery or while recovering from an injury, reducing inflammation and blood flow for faster rehabilitation. Using a pad that secures to the affected area with adjustable straps, the elegantly simple design provides safe, targeted relief; it is also effective in improving joint function. The clear insulated reservoir lets you know at a glance when refilling is required. The hose wraps around the tank and is held in place with built-in hooks for compact storage or transport. Convenient on/off switch.
