The Elasto-Gel All Purpose Therapy Wraps are hot or cold packs designed to provide thermal therapy to various body parts. The wraps are made of a tough flexible gel covered with a four-way stretch material to allow maximum conformity, heat transfer, and comfort. The packs are available in a number of different widths for use around the wrist, elbow, head, knee, or ankle. Each wrap serves for both heat and cold treatment, remaining soft and flexible at temperatures as low as -20 degrees Fahrenheit to autoclavable temperatures of up to 250 degrees. The wraps will remain cold for 20 to 40 minutes, and will provide heat for 20 to 30 minutes. The packs may be heated in a conventional or microwave oven, crockpot, or hydrocollator, and cooled in the freezer or refrigerator. The wraps are puncture resistant.
