Abstract
Abstract A method of applying a wound management dressing device. A foamed polyurethane pad of a selected size and having a hydrophilic side for contact with a wound and a hydrophobic side for facing away from the wound is positioned on a porous non-woven fibrous sheet of a larger selected size and having an adhesive on the side contacting the hydrophobic side of said pad so that the device presents the hydrophilic side and the adhesive for use in contact with the wound. A non-sticking removable cover is placed over the adhesive side of the sheet to prevent early exposure of the pad and the adhesive.
