  • Patent number: 11937893
    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, a release agent, and an optical fiber mesh layer configured as a light pipe, 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. Another aspect includes a pipe light pipe, as an alternative to the optical fiber mesh layer. The systems 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 the light pipe to transport or route light to the drape to deactivate the photosensitive adhesive layer and promote easy, clean, and less painful removal of the drape.

  • Publication number: 20210137628
    Abstract: Provided herein are systems and methods for controlling, inducing, and indicating adhesive deactivation of adhesive drape systems. 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 after exposure to an external stimulus, such as light. The system may have one or more photosensitive pigment areas that provide a visual indication based on exposure to the light. Another aspect provides a method for controlling the adhesion of a drape by application of a low-tack substance to one or more areas of a drape adhesive. The low-tack substance may be configured to produce a visual indication to distinguish areas where the low-tack substance has been applied. Such systems and methods enable a user to control properties of the drape adhesive and determine the various adhesive states via a visual indication.
