1. A negative pressure wound treatment apparatus, comprising:
a wound dressing configured to be positioned over a wound and skin surrounding the wound, the wound dressing comprising:
a porous contact layer configured to allow for fluid to pass there through, the porous contact layer positioned over the skin surrounding the wound;
a capillary layer located above the contact layer configured to allow transmission of fluid away from the wound;
an absorbent layer located above the capillary layer configured to form a reservoir for fluid removed from the wound, wherein the absorbent layer comprises a super absorbent polymer material; and
a cover layer located above the absorbent layer;
a negative pressure source configured to apply negative pressure to the wound through the contact layer and through the capillary layer and configured to draw fluid from the wound into the absorbent layer.
