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.

Claims

1. A method of treating wounds such as burns, abrasions, lacerations and surgical incision, comprising the steps of:

cleaning said wound;

applying to said wound a foam pad consisting essentially of polyurethane having a thickness ranging from 0.50 to 15.0 mm and sized to cover said wound and extending at least two cm beyond the wound edge, said pad having a hydrophilic side in contact with said wound, and a porous, non-woven fibrous sheet having a permeability to water vapor, carbon dioxide and oxygen of at least 175 cc/hour and sized larger than said pad size and having an adhesive side in contact with the pad, said sheet then being pressed on to the non-wounded portion of the patient'"'"'s skin to adhere the product to the patient; and

maintaining said pad in contact with said wound for five to seven days.
