Altrazeal® is a patented powder dressing specially engineered to cover and protect the wound and to provide an ideal moist wound healing environment that supports cellular function and tissue repair. Its non-resorbable, sterile granules aggregate when hydrated with saline to form a moist, flexible, oxygen permeable film that fits and seals the wound. The skin-like barrier serves many functions that promote healthy granulation tissue growth: 1. seals and protects the entire wound surface 2. allows oxygen transportation 3. manages exudate through vapor transpiration 4. prevents penetration of exogenous bacteria Altrazeal® enables extended wear time, allowing the wound to heal without disturbing the wound bed with frequent dressing changes.
