Abstract
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 plurality of apertures and may be adapted to cover the tissue site. 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. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.
Claims46
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, wherein the base layer is adapted to cover the tissue interface and tissue surrounding the tissue site,
- an adhesive configured to extend through the apertures at least in the periphery of the base layer to contact the tissue surrounding the tissue site,
- 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, wherein the first wicking layer has a grain structure adapted to wick fluid along a surface of the first wicking layer,
- a second wicking layer disposed in the enclosure, wherein the second wicking layer has a grain structure adapted to wick fluid along a surface of the second wicking layer,
- an absorbent layer disposed between the first wicking layer and the second wicking layer, and
- a conduit interface positioned proximate to the sealing member and in fluid communication with the enclosure;
- a reduced-pressure source adapted to provide reduced pressure to the dressing;
- and
- a conduit having an internal lumen coupled in fluid communication between the conduit interface and the reduced-pressure source, at least a portion of the conduit being comprised of an absorbent material that is vapor permeable and liquid impermeable.

A system for treating a tissue site, comprising:
- a tissue interface adapted to be positioned proximate to the tissue site and to distribute reduced pressure to the tissue site;
- a dressing adapted to provide reduced pressure to the tissue interface and to store fluid extracted from the tissue site through the tissue interface, comprising:
- a base layer having a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion, wherein the central portion of the base layer is adapted to be positioned proximate to the tissue interface and the periphery of the base layer is adapted to be positioned proximate to tissue surrounding the tissue site, wherein the periphery of the base layer is adapted to surround the tissue interface, and wherein the apertures in the base layer are adapted to be in fluid communication with the tissue interface and the tissue surrounding the tissue site,
- an adhesive configured to extend through the apertures in at least the periphery of the base layer to contact the tissue surrounding the tissue site, wherein the adhesive is adapted to be in fluid communication with the tissue surrounding the tissue site through the apertures in 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, wherein the first wicking layer has a grain structure adapted to wick fluid along a surface of the first wicking layer,
- a second wicking layer disposed in the enclosure, wherein the second wicking layer has a grain structure adapted to wick fluid along a surface of the second wicking layer,
- an absorbent layer positioned in fluid communication between the first wicking layer and the second wicking layer, and
- a conduit interface positioned proximate to the sealing member and in fluid communication with the enclosure;
- a reduced-pressure source adapted to provide reduced pressure to the dressing;
- and
- a conduit having an internal lumen coupled in fluid communication between the conduit interface and the reduced-pressure source, the conduit having a wall comprised of a hydrophilic polymer that is vapor permeable and liquid impermeable.
