ABSTRACT:
A non-occlusive, non-adherent dressing for wounds, the dressing comprising an imperforate (i.e. continuous) flexible film for contacting the wound, and an absorbent pad backing the wound-contacting film and extending beyond a substantial portion of the periphery of the film, the dressing having vapor transport cavity approximating that of intact human skin. The absorbent pad removes wound exudate from the proximate area of the wound without the pad coming into contact with the open wound itself. The final construction, comprising the film and absorbent backing, permits a measurable amount of moisture vapor to be transmitted (greater than 0.06 mg/cm.sup.2 /hr), thereby greatly reducing the degree of maceration and other problems that may be produced by a fully occlusive dressing.
