  • Patent number: 10893983
    Abstract: A method for dressing a wound is provided including providing a wound dressing pad of hydrophobic fabric that is treated to bind microorganisms; placing the hydrophobic fabric so that it faces the wound; and applying negative pressure therapy to the wound dressing so that microorganisms in the wound surface adhere to the dressing through hydrophobic interaction. The negative pressure therapy may be alternated with hyperbaric oxygen treatments of the wound dressing.

  • Patent number: 10893981
    Abstract: The invention herein relates to a wound dressing product, combining a hydrophobic fabric, which is to be placed towards the wound, and is capable of binding unwanted microorganisms, and a moisture carrying matrix such as a gel or a foam. The product of the invention is ideal for treatment of drier wounds. It protects the wound and reduces the number of pathogenic microorganisms, without using antimicrobial substances and at the same time adds or traps moisture to the wound both supporting the hydrophobic functioning of the pad and healing in general by keeping the wound moist.

  • Publication number: 20120238535
    Abstract: A new topical formulation is provided, with a high chemical stability, of for example a low dose clobetasol propionate, suitable for the topical treatment of skin and mucous membrane conditions associated with disorders including psoriasis, eczema, and other forms of dermatitis and also topical use associated with he mouth, such as lichen planus. The formulation includes an aqueous vehicle of based on propylene glycol as a solvent and moisture-retaining agent, and macrogol-glycerol hydroxystearate as a non-ionic emulsifier, being capable of holding surprisingly low concentrations of clobetasol. The vehicle holds concentrations about 0.005% to about 0.05% by weight of 17-clobetasol propionate, more preferably about 0.02 to 0.025%, even more preferably 0.025% by weight of 17-clobetasol propionate. The formulation has a good chemical stability, resulting in a long durability.

  • Patent number: 8263115
    Abstract: A ring-shaped toe-patch is provided for treatment and prevention of tinea pedis, commonly known as athlete's foot. The toe-patches are made of rubber-foam, attached to a hydrophobic material for elimination of fungus like T. rubrum. The toe-patch has cuts extending into the patch from the central circle in the toe-patch. Due to its perfect fit the toe-patch comes close to the affected area making it possible for a hydrophobic material attached to foam to effectively bind the fungi. Simultaneously with the elimination of the fungi the toe-patch works as a toe separator creating space between the toes.

  • Patent number: 7576256
    Abstract: A wound dressing product, combining both a traditional dressing with a mounted absorbent material and a hydrophobic fabric attached thereto, which is to be placed towards the wound, and is capable of binding unwanted microorganisms. The wound dressing product protects the wound, absorbs exudate and reduces the number of pathogenic microorganisms, without using antimicrobial substances, and consists of three bonded layers: hydrophobic cellulose acetate fabric which binds microorganisms, an attached efficient absorbent material, and a backing (cover) which is preferably visually transparent, semi-permeable and self-adhesive.
