Stratasorb Composite Dressing is a four layer composite dressing designed to cover all stages of wounds. Layer 1 is a non-adherent wound contact layer that protects the wound site and will not stick to granulating tissue. Layer 2 is a soft pad that absorbs drainage from the wound site. Layer 3 is a non-woven backing with an adhesive border that holds the wound contact pad in place. Layer 4 is a semi-occlusive, polyurethane film that helps keep external contaminants out, helps prevent strike-through, and maintains a moist wound environment.
