Publication number: 20100247613Abstract: A laminated dressing defining an area adapted to receive and hold medicine. In one embodiment of the invention, the dressing comprises a contact layer and a backing layer, both fabricated from absorbent materials. The contact layer has an inboard surface and an opposing outboard surface defined. The outboard surface of the contact layer is adapted to be applied to a patient's skin surrounding a wound. The contact layer further defines a die-cut through-opening substantially in the center of the contact layer. Adhering to the inboard surface of the contact layer is the backing layer, which likewise has an inboard surface and an opposing outboard surface defined. Medicine is received in the area defined by the through-opening in the contact layer and the inboard surface of the backing layer. A polymer film covers the outboard surface of the backing layer to prevent the escape of medicine from the dressing through the backing layer.Type: ApplicationFiled: March 31, 2009Publication date: September 30, 2010Applicant: WEBTEC Converting, LLC.Inventor: Randel B.

Patent number: 7790946Abstract: A wound dressing apparatus for use in subatmospheric pressure therapy includes an outer member dimensioned for positioning relative to a wound bed and defining an internal reservoir, a port associated with the outer member and in communication with the internal reservoir for applying subatmospheric pressure to the internal reservoir to facilitate treatment of the wound bed and removal of fluid therefrom, an inner member at least partially positionable within the wound bed and confined within the outer member, and an adhesive agent in contact with a peripheral section of the outer member to facilitate attachment of the peripheral section to the periwound tissue. The adhesive agent is preferably substantially devoid of contact with the inner member. In one embodiment, a layer of adhesive material is disposed on the peripheral section of the outer member.Type: GrantFiled: July 6, 2007Date of Patent: September 7, 2010Assignee: Tyco Healthcare Group LPInventor: Sharon Mulligan

Publication number: 20100222731Abstract: The adhesive bandage consists of a support with one surface having pressure sensitive adhesive and a wound covering pad placed centrally on it, which are covered by two protective detachable tear away tabs. The tear away tab consists of a single layer over the adhesive surface of the support and becomes two layered over the pad region. The two layers are fused at the zone of fusion near the margin of the pad, but are otherwise free from each other. The layer close to the pad, called inner barrier layer, completely covers the pad area. The outer layer, also called grasping layer, partially covers the barrier layer and the pad, and is folded upon itself to give sufficient length. When the outer layer is grasped to pull apart the releasable tear away tabs the inner barrier layer prevents contact of the finger to the pad. As one pulls apart the tear away tabs the barrier layers unfold and prevent contact of the fingers with the wound and wound exudates, preventing cross contamination.Type: ApplicationFiled: July 4, 2008Publication date: September 2, 2010Inventor: Kalpesh Jayantkumar Gajiwala

Patent number: 7683235Abstract: A dispenser assembly includes a housing having a face and an aperture that allows adhesive bandage carrier to pass through it. The adhesive bandage carrier comprises a longitudinally-extending carrier strip having a plurality of longitudinally-disposed adhesive bandages removably secured to an underlying carrier strip. The bandages are located at pre-determined and equally-spaced intervals along the strip. At the same intervals, the strip includes a plurality of apertures. A first edge of the bandage overlays a portion of an aperture such that the first edge can be easily grasped when the bandage is dispensed. The dispenser assembly also includes a number of rotational elements that serve as either “feed” mechanisms for delivering a roll of adhesive bandage carrier from within the container or “take-up” mechanisms for accumulating protective material that overlays the bandage carrier. Different embodiments of the assembly afford mechanical and electrical actuation of the dispensing assembly.Type: GrantFiled: February 10, 2006Date of Patent: March 23, 2010Inventor: John W. Wendorf
