Claims20
A wound dressing comprising:
- a wound contact layer;
- a cover layer sealed to the wound contact layer;
- an absorbent layer for absorbing wound exudate positioned between the wound contact layer and the cover layer;
- and
- a force shielding layer positioned above the absorbent layer, wherein the force shielding layer is configured for spreading force applied to the wound dressing at a first area over a second area, wherein the second area is larger than the first area;
- wherein the force shielding layer is configured to increase the area over which a pressure applied to the dressing is transferred by 25% or more of the initial area of application and
- wherein the force shielding layer comprises two cooperating sub-layers.
