The Acu-Life Finger Injury System, model 400563, is a hot or cold therapy system and finger extension splint designed for use by individuals with finger injuries or arthritis. The kit contains a finger gel pack and a comfort splint that can be used to treat the two stages of finger injuries. In the first stage, the gel pack allows the user to administer cold therapy three or four times a day to reduce swelling and soreness. In the second stage, the splint can be used to protect the recovering finger while immobilization is needed. In addition, the kit includes a finger pack that provides targeted heat relief for arthritic fingers.
