Claim:
1. A perforated wound dressing, comprising: a first layer including a first set of spaced protrusions, each protrusion comprising an underside configured to face a wound and shaped to receive medication for treating the wound; a second layer overlying and directly adjacent to the first layer, including a second set of spaced protrusions, the second set of spaced protrusions being of similar shape to and aligned with the first set of spaced protrusions and wherein the second layer is harder than the first layer such that the second set of spaced protrusions better withstand compression; and a plurality of cylindrical holes defined through the first layer and the second layer, the holes configured to allow evaporation of exudate from the wound to pass through the perforated wound dressing in a direction substantially perpendicular to the wound's surface.
