Wound dressing and method of treatment

1. A wound dressing for placement at a wound site, the wound dressing comprising:

a wound contact layer;

an absorbent layer for absorbing wound exudate, the absorbent layer positioned above the wound contact layer and comprising superabsorbent material;

a foam layer positioned over the absorbent layer; and

a cover layer positioned above the foam layer;

wherein the foam layer is in direct contact with the cover layer and a majority of the foam layer is visible through the cover layer; and

wherein the wound contact layer carries an adhesive portion at least at a periphery of a lower surface thereof, the adhesive portion for forming part of a substantially fluid tight seal around the wound site; and

wherein an upper surface of the wound contact layer is sealed to a lower surface of the cover layer.

2. The wound dressing of claim 1 , wherein the foam layer comprises an open celled foam configured to allow transmission of gas or vapor therethrough.

3. The wound dressing of claim 1 , wherein the foam layer is configured for spreading pressure applied to the wound dressing at a first area over a second area, wherein the second area is larger than the first area.

4. The wound dressing of claim 1 , wherein the foam layer comprises at least one of polyurethane and polyester.

5. The wound dressing of claim 1 , wherein the foam layer is configured to at least partially obscure a view of wound exudate absorbed by the absorbent layer in use.

6. The wound dressing of claim 1 , wherein the cover layer is moisture vapor permeable.

7. The wound dressing of claim 1 , wherein the absorbent layer comprises cellulose fibres.

8. The wound dressing of claim 1 , wherein the wound dressing further comprises a transmission layer between the wound contact layer and the absorbent layer.

9. The wound dressing of claim 1 , wherein the wound dressing further comprises an indicator for indicating the need to change the dressing.

10. The wound dressing of claim 1 , wherein the wound dressing further comprises a suction port above an orifice of the cover layer, wherein the suction port is configured to be fluidically connected to a source of negative pressure.

11. The wound dressing of claim 10 , wherein the wound dressing further comprises a filter attached to the suction port over the orifice of the cover layer.

12. The wound dressing of claim 10 , wherein the suction port comprises a transparent material.

13. The wound dressing of claim 10 , wherein the suction port is situated closer to one end of the dressing, contrasted with a central position of the dressing.

14. A wound dressing for placement at a wound site, the wound dressing comprising:

a wound contact layer;

an absorbent layer for absorbing wound exudate, the absorbent layer positioned above the wound contact layer;

an open-celled foam layer over the absorbent layer; and

a moisture vapour permeable cover layer, comprising a moisture vapor permeable film;

wherein the foam layer is in direct contact with the cover layer and a majority of the foam layer is visible through the cover layer; and

wherein the foam layer is configured to at least partially obscure a view of wound exudate absorbed by the absorbent layer in use; and

wherein an upper surface of the wound contact layer is sealed to a lower surface of the cover layer.

15. The wound dressing of claim 14 , wherein the foam layer is configured for spreading pressure applied to the wound dressing at a first area over a second area, wherein the second area is larger than the first area.

16. The wound dressing of claim 14 , wherein the foam layer comprises at least one of polyurethane and polyester.

17. The wound dressing of claim 14 , wherein the absorbent layer comprises superabsorbent material.

18. The wound dressing of claim 14 , wherein the wound dressing further comprises an indicator for indicating the need to change the dressing.
