Abstract

A medical dressing is provided. The dressing has a central portion and a border portion, and comprises a backing layer, an adhesive body contact layer and a pad arranged in the central portion between the backing layer and the adhesive body contact layer. The pad is symmetric about a longitudinal center line and the dressing comprises a lobed portion on each side of the center line. The central portion of the dressing has a tensile strength in the longitudinal (y) direction of at least 60 N, preferably at least 70 N at an elongation of 25%, as measured by the test method ASTM D 882-12. The medical dressing may be used for pressure ulcer prevention, such as at the sacrum region of a human body.
