Abstract
Abstract A compression bandage includes a bandage strip with an absorbent layer on one side. A pressure piece of slightly deformable and slightly absorbent molded material is attached to the other side of the strip opposite the absorbent layer. When the bandage is applied and the strip wound around the injured part, the pressure pad exerts pressure through the strip and absorbent layer onto the wound, and cannot slip from the correct position.
