Gaymar T-Pump Localized Heat Therapy Systems are used to treat many different pain conditions including chronic arthritis, localized pain, muscle spasms, wounds, and phlebitis. The power unit supplies water of a controlled temperature through hoses to a pad that it applied to the patient for localized warming. The heat therapy system is designed for single patient use and can also be used along with hot/cold therapy. New improved model is quieter and more efficient.
