Features of the Medline Optifoam Adhesive Foam Dressings: Optifoam's waterproof, polyurethane backing helps maintain an optimally moist wound environment, helps prevent strike-through, and aids in the prevention of bacterial contamination of the wound. Backing's moisture vapor transmission rate adjusts depending on the fluid level in the wound. Foam pad has micropores for low adherence to wound surface, yet has a higher fluid-handling capacity than other brands. Foam island gently expands as it absorbs, keeping the dressing in contact with the wound surface for improved fluid handling. With one of the largest catalogs of medical, surgical and diagnostic supplies available online, Medex Supply can accommodate your facility's needs for Wound Care. Foam Dressings can be found in our extensive online collection of products from globally recognized and trusted brands, including Medline. An excellent option to consider is the Optifoam Adhesive Foam Dressings.
