Abstract: Provided herein is a system and method for trauma-free application and removal of light deactivated adhesive drapes. One aspect provides a system comprising a drape, at least one photosensitive adhesive portion having a release agent, and at least one acrylic and/or polyurethane adhesive portion, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing the removable blocking layer and applying light to the drape to deactivate the photosensitive adhesive portion and promote easy, clean, and less painful removal of the drape. When the photosensitive adhesive portion is deactivated, the acrylic and/or polyurethane adhesive portion maintains adhesion between the drape and the tissue until removal of the drape.

Abstract: Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.
