Claim 18:
19. A medical dressing for application to a contoured surface of a human body, said dressing having a central portion and a surrounding border portion and a lateral (x) direction and a longitudinal (y) direction; wherein said dressing comprises:—a backing layer—an adhesive body contact layer, and—a multi-layered pad arranged between said backing layer and said adhesive body contact layer, wherein said multi-layered pad comprises at least a first layer that has a higher affinity for liquid than a second layer, and a third layer comprising a polyurethane foam; wherein said backing layer and said adhesive body contact layer extend beyond the periphery of said pad to define said border portion along the contour of said pad; said pad being symmetric about a longitudinal center line and comprising a first lobed portion on one side of said longitudinal center line and a second lobed portion on the other side of said longitudinal center line; wherein said adhesive body contact layer comprises a film covered by an adhesive layer, the adhesive body contact layer further comprising a plurality of perforations extending through the adhesive body contact layer for aiding absorption of liquid into the pad; wherein said second layer of said multi-layered pad comprises a nonwoven material; wherein the central portion has a tensile strength at 25% elongation in the longitudinal (y) direction that is at least four times higher than the tensile strength at 25% elongation in the lateral (x), such that the dressing is more stretchable in the lateral (x) direction, and wherein the central portion has a tensile strength in the longitudinal (y) direction of at least 70N per 50 mm at 25% elongation, as measured by the test method ASTM D 882-12.
