  • Publication number: 20240041657
    Abstract: Non-adhesive articles include an elastomeric layer, where the elastomeric layer has a plurality of cuts arrayed in a pattern. The cuts are gaps, but the gaps are not visible to the naked eye when the article is in an unstressed state, and in a stressed state, at least some of the cuts become gaps that are visible to the naked eye. The gaps are perforations in the elastomeric layer and are apertures through which one can view through the elastomeric layer. The perforations indicate the presence of stress in the article, and the elastomeric layer has a lower effective modulus of elasticity in at least one axis than an identical elastomeric layer without the plurality of cuts.

  • Patent number: 11691384
    Abstract: Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.

  • Publication number: 20230181800
    Abstract: Polymeric tubing containing extractable component(s) for use in medical articles include a tube and a vapor-deposited coating of a barrier polymer covering at least a portion of the tube. The barrier polymer is derived from at least one ethylenically unsaturated monomer. The vapor-deposited polymer coating reduces the extraction of extractable component(s) from the tube. The barrier polymer is parylene or a copolymer of parylene. The polymer coated tubing can be used in stethoscopes.

  • Publication number: 20230078390
    Abstract: Medical adhesive articles include a layer of adhesive and a modified substrate layer where the layer has a plurality of cuts arrayed in a pattern that may be random or the pattern can be arrayed along at least one axis. The cuts are gaps, but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, and at least some of the cuts become gaps that are visible to the naked eye and form apertures when the adhesive article is in a stressed state. The adhesive articles can be used to adhere a medical device to skin.

  • Patent number: 11511522
    Abstract: The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, a (meth)acrylate monomer, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPa·s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88%, and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

  • Publication number: 20220226161
    Abstract: Medical dressings including stiffening systems fixedly attached to backing layers are described herein along with methods of using the medical dressings. The stiffening system is fixedly secured to the backing to limit flexing and stretching of the backing layer. Typically, the medical dressing and stiffening system is applied over a medical device that is secured to skin. The stiffening system covers some of the medical device and also extends beyond the medical device. The stiffening system stabilizes the medical device over the skin.
