Abstract
Disclosed is a vented dressing comprising a thin conformable vapor-permeable, liquid-impermeable sheet material having a generally centrally disposed wound-covering portion for placement directly over the wound and a peripheral portion defining the central portion and which is intended to be secured to the whole skin surrounding the wound, the sheet material having a coating of a pressure-sensitive adhesive extending substantially entirely over one surface thereof for adhering the dressing to the body, the adhesive coating being applied so as to provide repeating areas containing no adhesive, areas of the wound-covering portion of the sheet material where there is no adhesive having slits extending through the thickness thereof to permit venting of wound fluids therethrough, the areas of no adhesive in peripheral portion being free of any slits whereby passage of wound fluids therethrough is precluded, the peripheral areas of the sheet material having no adhesive however permitting vapor transmission therethrough whereby to inhibit maceration of the skin beneath the peripheral areas.
