A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed. |

1. A system for treating a tissue site, comprising:
a tissue interface adapted to be positioned proximate to the tissue site; a dressing, comprising:
a base layer having a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion, the apertures in the periphery being larger than the apertures in the central portion, at least one of the apertures in the periphery being positioned at an edge of the periphery and having an interior exposed at the edge, and wherein the base layer is adapted to cover the tissue interface and tissue surrounding the tissue site,an adhesive in fluid communication with the apertures at least in the periphery of the base layer,a sealing member having a periphery and a central portion, the periphery of the sealing member positioned proximate to the periphery of the base layer, wherein the central portion of the sealing member and the central portion of the base layer define an enclosure,a first wicking layer disposed in the enclosure,a second wicking layer disposed in the enclosure,an absorbent layer disposed between the first wicking layer and the second wicking layer, anda conduit interface positioned proximate to the sealing member and in fluid communication with the enclosure; and a reduced-pressure source adapted to be coupled in fluid communication with the conduit interface to provide reduced pressure to the dressing. |
