  • Publication number: 20200188552
    Abstract: Film forming gel compositions, useful in creating conformable and flexible gel bandages, can be formulate from a film forming polymer, a tackifier, and a volatile solvent. The film forming gels can also include antiseptics, cationic polymer coagulants, fillers, and other additives. The gel compositions form relatively thick films when dried on tissue, and can exhibit enhanced breathability to promote wound healing.

    Abstract: Conformable coating composition are described comprising a (meth)acrylate copolymer comprising interpolymerized monomer units of fluorinated monomer and a volatile solvent having a solubility parameter from 4.9-12.5 (cal/cm3)1/2. In some embodiments, the fluorinated monomer has a Tg <30° C. In some embodiments, the dried coating exhibits no blocking and no greater than 75% failure at an elongation of 100%. Also described is a conformable film comprising a dried coating composition of the coating compositions described herein, articles comprising a layer of the conformable film on a substrate, and a copolymer comprising interpolymerized units of fluorinated monomer(s), silane monomer(s); and one or more monomers having a Tg ?50° C.

  • Publication number: 20200038546
    Abstract: Provided is a method of forming a fibrinogen hydrogel composition, the method including providing a fibrinogen hydrogel or precursor thereof, comprising fibrinogen hydrogel forming salt. The fibrinogen hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrinogen hydrogel. The method further includes denaturing the fibrinogen hydrogel such as by heating. The method optionally further includes combining the fibrinogen hydrogel with a carrier material. When present, the concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrinogen hydrogel.

  • Publication number: 20200030486
    Abstract: A method of forming a fibrin hydrogel composition including providing one or more unitary masses of a fibrin hydrogel, dividing at least one of the unitary masses of the fibrin hydrogel into a multiplicity of smaller pieces of the fibrin hydrogel, and recombining at least a portion of the smaller pieces into a cohesive mass. Dividing at least one of the unitary masses of fibrin hydrogel into a multiplicity of smaller pieces may include shearing or cutting the unitary masses to form an aqueous dispersion of the fibrin hydrogel in an aqueous medium. The aqueous dispersion of fibrin hydrogel may be applied to a substrate on a roller or an endless belt, and is optionally overlaid by a scrim. The cohesive mass of fibrin hydrogel, which may be formed by removing at least a portion of the aqueous medium from the aqueous dispersion of the smaller pieces of the fibrin hydrogel, finds uses in wound dressing articles.

  • Patent number: 10466219
    Abstract: A vapor sensor comprises a housing with an inlet opening in fluid communication with a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to an output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.
