Wound dressing and method of treatment

1. A wound dressing, comprising:

an absorbent layer for absorbing wound exudate;

wherein the dressing is shaped to include a plurality of sub-areas, wherein the dressing has rotational symmetry, and the sub areas define areas of the dressing that are formable in different directions with respect to each other.

2. The wound dressing of claim 1 , wherein the dressing comprises four sub-areas.

3. The wound dressing of claim 1 , further comprising at least one of a wound contact layer, a foam layer, an odour controlling element, a shielding layer and a cover layer.

4. A wound dressing comprising:

a wound contact layer;

a cover layer sealed to the wound contact layer; and

an absorbent layer for absorbing wound exudate positioned between the wound contact layer and the cover layer;

wherein the wound contact layer, cover layer, and absorbent layer are shaped in a conformable shape including a plurality of sub-areas, wherein the sub areas define areas of the wound dressing that are formable in different directions with respect to each other;

wherein the conformable shape has rotational symmetry around a center point of the conformable shape.

5. The wound dressing of claim 4 , wherein the conformable shape comprises four rounded lobes extending from a central portion of the dressing.

6. The wound dressing of claim 4 , further comprising a masking layer for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use, the masking layer positioned between the absorbent layer and the cover layer.

7. The wound dressing of claim 6 , wherein the masking layer is formed in the conformable shape including the plurality of sub-areas.

8. The wound dressing of claim 7 , wherein the conformable shape of the masking layer has a smaller dimension than the conformable shape of the absorbent layer whereby the masking layer is positioned over a central region of the absorbent layer and is not positioned over a radially outer border region of the absorbent layer.

9. The wound dressing of claim 6 , wherein the cover layer and the masking layer are permeable to one or both of gas and vapour.

10. The wound dressing of claim 9 , wherein the masking layer comprises, or is coated with, a material having size-exclusion properties for selectively permitting or preventing passage of molecules of a predetermined size or weight, the molecules comprising proteins.

11. The wound dressing of claim 6 , further comprising a shielding layer positioned above the absorbent layer, wherein the shielding layer comprises the masking layer, the shielding layer 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.

12. The wound dressing of claim 11 , wherein the shielding layer increases the area over which a pressure applied to the dressing is transferred by 25% or more or the initial area of application.

13. The wound dressing of claim 11 , wherein the shielding layer comprises two or more sub-layers, wherein a first sub-layer comprises through holes and a further sub-layer comprises through holes and the through holes of the first sub-layer are offset from the through holes of the further sub-layer.

14. The wound dressing of claim 4 , further comprising at least one layer positioned between the absorbent layer and the wound contact layer; wherein a dimension of the absorbent layer is larger than a dimension of the at least one layer such that a radially outer region of the absorbent layer forms an enclosure with the wound contact layer around the at least one layer.

15. The wound dressing of claim 14 , wherein the at least one layer comprises a foam layer positioned between the absorbent layer and the wound contact layer.

16. The wound dressing of claim 14 , wherein the at least one layer comprises an odour controlling element positioned between the absorbent layer and the wound contact layer.

17. The wound dressing of claim 4 , wherein the wound contact layer carries an adhesive portion on a lower surface thereof, the adhesive portion for forming a substantially fluid tight seal over the wound site.

18. The wound dressing of claim 4 , wherein the wound contact layer and cover layer are moisture vapor permeable.

19. The wound dressing of claim 18 , further comprising a moisture vapor permeable adhesive sealing the cover layer and the wound contact layer around the border region.

20. The wound dressing of claim 4 , wherein the cover layer comprises a translucent film having a moisture vapour permeability of 500 g/m 2 /24 hours or more.

21. The wound dressing of claim 4 , wherein the wound dressing has a border region and a central region, wherein the cover layer is sealed to the wound contact layer within the border region, and wherein the absorbent layer is positioned within the central region.
