Systems and methods for mitigating premature light deactivation of light deactivated adhesive drapes
Patent number: 11925432Abstract: 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, an 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 photochromic layer that may transition between a blocking transmittance state and a non-blocking transmittance state to block or allow certain wavelengths of light to pass through. Some systems may use a combination of a photochromic layer and a filter layer to prevent the adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing one or more of a photochromic layer and a filter layer and applying light to the drape to deactivate the adhesive layer and promote easy, clean, and less painful removal of the drape.Type: GrantFiled: September 4, 2018Date of Patent: March 12, 2024Assignee: 3M Innovative Properties CompanyInventors: Justin Alexander Long, Timothy Mark Robinson, Christopher Brian Locke -
