Abstract:
1. A wound dressing comprising: a base layer having a perimeter area, the base layer being resistant to penetration by liquid, the base layer including an inner adhesive band, and an outer adhesive band, the base layer defining an open area in a central portion of the base layer, the inner adhesive band and the outer adhesive band defining a non-adhesive space between the inner adhesive band and the outer adhesive band, the inner adhesive band and the outer adhesive band connected to one another through connection legs spaced around the non-adhesive space, the inner adhesive band, outer adhesive band and connection legs covered by a removable protective layer, the protective layer having a plurality of perforated lines spaced about the protective layer with a plurality of non-perforated sections between the perforated lines such that when the protective layer is removed, separation occurs at the perforated lines and only one non-perforated section is removed at a time; an inner layer, the inner layer having an outer edge defining an inner layer area, the inner layer area including a plurality of drain holes inward of the outer edge and spaced near the perimeter of the inner layer, the inner layer being resistant to penetration by liquid; an absorbent layer adjacent the inner layer; and an outer layer adjacent the absorbent layer and attached to the inner layer, the outer layer being resistant to penetration by liquid, at least one of the inner layer and the outer layer including an attachment adhesive band, the attachment adhesive band surrounding an area inward of the attachment adhesive band, the area being at least as large as the open area of the base layer, the attachment adhesive band covered by a removable protective layer, the protective layer having a plurality of perforated lines spaced about the protective layer with a plurality of non-perforated sections between the perforated lines such that when the protective layer is removed, separation occurs at the perforated lines and only one non-perforated section is removed at a time, the outer layer adapted to be placed over the open area of the base layer and to be attached to the base layer by the attachment adhesive band.
