Allegiance Kwik Heat™ Perineal Warm Pack

Perineal Hot Pack

Cold and Hot Disposable Pack

Allegiance Kwik Kold™ Peri Cold Pack Large Adult Hot Pack

The Allegiance Kwik Heat™ Perineal Warm Pack is comprised of an outer pouch which is secured to a perineal pad and then wrapped in a polyester material. The heat source pouch consists of a supercooled solution of sodium thiosulfate, dextrose and water. The sodium thiosulfate, dextrose and water "bubble" is housed in a separate plastic pouch inside the outer pouch. The perineal pad is made of a non-woven wrapped cellulose wood pulp fiber. Activation of the heat source occurs by folding the unit to open the inner bubble which releases the liquid, and kneading the unit, thus creating a physical exothermic reaction.
