  • Patent number: 9486366
    Abstract: A method is provided to attach a grip tab along an edge of a carrier layer of a film dressing web, which includes a film layer coated with adhesive on a first side and a carrier layer releasably attached to the film layer on an opposed second side. The method includes choosing a material for the carrier layer that is heat welding incompatible with the film layer, feeding the web in a machine direction, applying a first strip of a material that is heat welding compatible with the carrier layer along part of an edge portion of the web extending parallel to the machine direction, and affixing the first strip to the carrier layer while simultaneously cutting away an outermost part of the web with the first strip applied thereto by passing the web through an ultrasonic welding device.

  • Patent number: 8998863
    Abstract: An apparatus and method are provided for treating wound with negative pressure. The apparatus includes a wound cover, a first pump for providing said negative pressure at a chosen pressure level to the wound, a canister, a first conduit between the wound cover and the canister, first means for measuring the pressure within the canister, and a second conduit which connects the canister with the first pump. A circulating pump is arranged to intermittently transport a gas volume from the canister to the wound region via a third conduit and back to the canister via the first conduit in order to press out possible exudates from the first conduit to the canister. A second means analyzes the pressure curve over time of said pressure in the canister and a third means indicates by alarm when said pressure curve differs from a normal cyclical form.

  • Patent number: 8986270
    Abstract: A device for treatment of wounds using reduced pressure is provided. The device includes a pump, a reservoir connected to the pump for collecting exudate from a wound, an inlet to the reservoir for connecting the reservoir with the wound so as to allow the pump to expose the wound to the reduced pressure, a wound pad to be arranged in the wound cavity, and a sealing covering the wound and the wound pad. The wound pad consists of an open-cell polyurethane foam which is fully impregnated with a soft hydrophobic silicone gel. The foam has a hardness of 1.0-6.0 kPa measured according to ISO 3386-1 at 40% compression. Also provided is a wound pad to be used with an absorbent member. In addition, provided is a method for manufacturing the wound pad.

  • Patent number: 8652112
    Abstract: An ostomy device is provided including an ostomy pouch having an entrance opening, a body attachment wafer having a through-going opening and a coupling layer, which couples the pouch to the body attachment wafer and has a central opening therein. The body attachment wafer includes a plastic film, which is coated with a layer of skin friendly adhesive on the side thereof distal to the ostomy pouch. The coupling layer is affixed to the body attachment wafer along an attachment line extending around the central opening in the coupling layer, the attachment line being distanced from the central opening in the coupling layer. The region around the entrance opening of the pouch is affixed to the coupling layer in a landing zone located between the attachment line and the opening in the body attachment wafer.
