Systems and methods for mitigating premature light deactivation of light deactivated adhesive drapes using a filtering layer
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.

7. The system of claim 1 , wherein the solvent is a non-water soluble solvent or wherein the solvent is isopropyl alcohol (IPA), and wherein the flexible film layer is a breathable layer or polyurethane.
8. The system of claim 1 , wherein the one or more of the acrylic and the polyurethane adhesive layer comprises a thin film or a thick gel.
9. The system of claim 1 , further comprising at least one layer of light sensitive ink configured to change color upon exposure to the plurality of light wavelengths that activate the at least one release agent, wherein the removable filter layer comprises a plurality of pattern coats each configured to block a separate range of the plurality of light wavelengths that activate the at least one release agent, wherein at least one of the plurality of pattern coats is insoluble to isopropyl alcohol (IPA), and wherein the at least one of the plurality of pattern coats insoluble to IPA is configured to be peeled off from an outer surface of one or more of the drape and the removable filter layer.
10. The system of any of claim 1 , wherein the removable filter layer further comprises a filter adhesive layer, wherein the removable filter layer and the filter adhesive layer comprise a single, combined layer.
11. A kit comprising:
a drape system, wherein the drape system comprises:
a drape comprising:
a photosensitive adhesive layer comprising an adhesive release layer and one or more of an acrylic or polyurethane adhesive layer, the photosensitive adhesive layer having at least one release agent disposed within the photosensitive adhesive layer, wherein the at least one release agent is configured to weaken a bond of the photosensitive adhesive layer to tissue upon exposure to at least one of a plurality of light wavelengths, the plurality of light wavelengths comprising a portion of a visible light spectrum;
a flexible film layer coupled to the photosensitive adhesive layer; and
a removable filter layer coupled to the flexible film layer opposite the photosensitive adhesive layer, the removable filter layer being a partially transparent colored layer that includes at least one light absorbing dye corresponding to one or more colors of the visible light spectrum, the one or more colors of the visible light spectrum having wavelengths different from the plurality of light wavelengths that activate the at least one release agent, and wherein the removable filter layer is configured to block the plurality of light wavelengths that activate the at least one release agent and be removable upon exposure to a solvent; and
at least one wipe containing the solvent.
12. The kit of claim 11 , wherein the polyurethane adhesive layer is disposed between the adhesive release layer and the flexible film layer.
13. The kit of claim 12 , wherein the flexible film layer is a printed layer.
14. The kit of claim 11 , wherein the drape system and the at least one wipe are sterile.
