Abstract

A dressing includes a drape, a pressure-sensitive acrylic-based adhesive on a skin-facing surface of the drape, an island of absorbent material, a silicone gel backing film, and a silicone gel on the silicone gel backing film. The drape is a thin film capable of maintaining a negative pressure underneath the drape upon application of a vacuum. The island of absorbent material has a smaller area than the drape and is applied onto the skin-facing surface of the drape. The silicone gel backing film has a frame shape and a smaller footprint than the drape and a larger footprint than the island of absorbent material.
