A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a liquid impermeable, gas permeable filter layer over the absorbent layer, a cover layer comprising at least one orifice and a first liquid and gas permeable transmission layer underlying the absorbent layer. The transmission layer is in fluid communication with the filter layer.
1. A wound treatment apparatus, comprising: a dressing comprising: a wound contact layer;a cover layer;a first layer disposed in a space between the cover layer and the wound contact layer, wherein the first layer comprises a porous material;a second layer disposed in the space and made of a differe
1. A wound treatment apparatus, comprising: a dressing comprising: a wound contact layer;a cover layer;a first layer disposed in a space between the cover layer and the wound contact layer, wherein the first layer comprises a porous material;a second layer disposed in the space and made of a different material than the first layer,an absorbent layer comprising superabsorbent material positioned in fluid communication between the first layer and the second layer, wherein the absorbent layer is above the first layer and below the second layer, wherein the first layer has a perimeter that is the same size and shape as a perimeter of the second layer, and wherein the perimeters of the first and second layers are larger than a perimeter of the absorbent layer; anda connector in fluid communication with the space for connecting the space to a source of negative pressure;wherein the first layer and the second layer allow transmission of fluid around the perimeter of the absorbent layer. 2. The apparatus of claim 1, wherein the second layer comprises a foam transmission layer. 3. The apparatus of claim 1, wherein the second layer comprises a porous, non-woven layer. 4. The apparatus of claim 1, wherein the first layer comprises a porous, non-woven material and the second layer comprises a foam layer. 5. The apparatus of claim 1, further comprising a source of negative pressure configured to apply negative pressure to the dressing through the connector. 6. The apparatus of claim 1, further comprising a filter positioned in fluid communication between the second layer and the connector. 7. The apparatus of claim 6, wherein the filter is sealed to the cover layer to cover at least one opening in the cover layer. 8. The apparatus of claim 1, wherein the cover layer is secured to the wound contact layer. 9. The apparatus of claim 1, wherein the cover layer comprises a moisture vapor permeable material. 10. A wound treatment apparatus, comprising: a dressing comprising: a wound contact layer having a periphery surrounding a central portion, wherein the wound contact layer is adapted to cover a wound site and skin surrounding the wound site;a cover layer having a periphery and a central portion, the periphery of the cover layer positioned proximate the periphery of the wound contact layer, wherein a space is defined underneath the cover layer and above the wound contact layer;a first transmission layer disposed in the space;a second transmission layer disposed in the space;an absorbent layer positioned in fluid communication between the first transmission layer and the second transmission layer, wherein a peripheral portion of the first transmission layer is directly in contact with a peripheral portion of the second transmission layer providing a fluid transmission path around the peripheral edges of the dressing; anda connector in fluid communication with the space for connecting the space to a source of negative pressure. 11. The wound treatment apparatus of claim 10, wherein the dressing is adapted to provide negative pressure to the wound site and to store fluid extracted from the wound site. 12. The wound treatment apparatus of claim 10, wherein the central portion of the wound contact layer is adapted to cover the wound site and the periphery of the wound contact layer is adapted to be positioned proximate the skin surrounding the wound site. 13. The wound treatment apparatus of claim 10, wherein the wound contact layer comprises silicone. 14. The wound treatment apparatus of claim 10, wherein the cover layer comprises polyurethane. 15. The wound treatment apparatus of claim 10, wherein the first and second transmission layers are adapted to transmit fluid away from the wound site. 16. The wound treatment apparatus of claim 10, wherein the absorbent layer comprises a superabsorber material that is adapted to absorb fluid. 17. The wound treatment apparatus of claim 10, further comprising an anti-microbial disposed in the space underneath the cover layer and above the wound contact layer. 18. The wound treatment apparatus of claim 10, further comprising an odor trapping element adapted to substantially preclude the passage of odors out of a sealed space between the cover layer and the wound site, wherein the odor trapping element comprises carbon. 19. The wound treatment apparatus of claim 10, further comprising a hydrophobic filter adapted to substantially preclude the passage of liquids out of the dressing. 20. The wound treatment apparatus of claim 19, wherein the hydrophobic filter is sealed to the cover layer and covers an opening in the cover layer. 21. The wound treatment apparatus of claim 10, wherein the cover layer is secured to the wound contact layer. 22. The wound treatment apparatus of claim 10, further comprising a source of negative pressure configured to apply negative pressure to the dressing through the connector. 23. The wound treatment apparatus of claim 10, wherein the fluid transmission path around the peripheral edges of the dressing allows fluid to be transmitted from the first transmission layer to the second transmission layer and around the absorbent layer.
