  • Patent number: 9035122
    Abstract: A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid.

    Abstract: Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. In some specific embodiments, the devices and methods may treat wounds on the head, neck, and face. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material.

  • Patent number: 9017302
    Abstract: A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port.

  • Publication number: 20150112287
    Abstract: The invention generally relates to dextran fibers which are preferably electrospun and devices formed from such fibers. In particular, such devices may include substances of interest (such as therapeutic substances) associated with the electrospun fibers. Upon exposure to a liquid the electrospun fibers dissolve immediately and the substances of interest are released into the liquid. Exemplary devices include bandages formed from electrospun dextran fibers and associated agents that promote hemostasis, such as thrombin and fibrinogen.

  • Patent number: 9012714
    Abstract: A wound treatment device comprises a wound surface contacting plug and a cover for covering the wound surface and the plug, wherein said plug consists of a flat textile isolating material comprising at least one first surface layer, one second surface layer and one intermediate space arranged between said surface layers. At least the first surface layer is provided with a biocompatible surface and a structure which enables a liquid to pass and prevents a wound tissue from growing in said structure. The intermediate space is provided with isolating threads elastically holding the first surface layer and the second surface layer at a certain distance from each other.

  • Patent number: 9005174
    Abstract: The invention is intended to provide an adhesive patch which contains a drug except bisoprolol and which effectively inhibits the occurrence of oozing out or sticking out of the adhesive layer components from the exposed area of the adhesive layer of the adhesive patch during storage as well as the occurrence of oozing out of the drug from the adhesive layer thereby preventing the reduction in drug content. The support, the release liner and the adhesive layer constituting the adhesive patch each are formed to have a rectangular planar shape and the entire adhesive patch are formed to have a rectangular planar shape, and a protrudent part is formed on the support-side surface of the adhesive patch at a corner thereof. In addition, the adhesive patch may be formed to have a middle part and a peripheral part, and the protrudent part may be formed at a corner of the rectangular middle part.

  • Patent number: 8993829
    Abstract: A bandage and method for securing a tension member comprising a central body and a plurality of tabs disposed about the central body. A tension member may be disposed across or through a slit or aperture of the central body. A body adhesive on the lower surface of the central body may secure the bandage to the patient. The tension member may then be pulled across the upper surface of the central body and a first tab may be folded over and adhered to the tension member and central body. The tension member may then be pulled back across the first tab and a second tab may be folded over and adhered to the tension member and first tab. Likewise, the tension member may then be pulled back across the second tab and a third tab may be folded over and adhered to the tension member and second tab.
