Abstract:
Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, a photosensitive adhesive layer, and a release agent, 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 filter layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. The filter layer may be printed directly onto the drape and may be removable after exposure to a solvent, such as isopropyl alcohol (IPA). The filter layer may also be a filter adhesive layer. Another aspect provides a method for application and removal of a drape using by removing one or more of the filter layer and/or the filter adhesive layer and applying light to the drape to deactivate the photosensitive adhesive layer and promote easy, clean, and less painful removal of the drape.
