  • Publication number: 20120064145
    Abstract: The present invention discloses a wound dressing which may be a double-layer wound dressing, comprising a polymer material layer in combination with anti-infective antibiotics or anti-infective Chinese herb medicine at the upper layer of the wound dressing, and a porous carbon material layer capable of loading with skin-associated epithelial cells at the lower layer of the wound dressing. The wound dressing with the antibiotics can block effectively the invasion of bacteria in the external environment, thereby preventing the wound from secondary infection. While covering the wound site, the porous carbon material layer with the epithelial cells can thus provide the healthy epithelial cells and attract the surrounding healthy cells to aggregate for secreting collagen so as to promote the wound healing process. According to the present invention, there is an obviously enhancing effect on wound tissue regeneration, restoration and healing, and there is a grant development potential in clinical applications.

  • Patent number: 7999146
    Abstract: A dressing and method for treating high-tension wounds. First and second layers of a 2-octyl cyanoacrylate 16 adhesive are applied to a short, high-tension wound, with the first and second layers covering the wound and extending to at least about 2.5 mm (0.0984 in.) from each side of the wound. The first layer is allowed to set and polymerize before the second layer of 2-octyl cyanoacrylate is applied. The second layer extends at least about 2.5 mm (0.0984 in.) beyond each edge of the first layer. In the case of a long, high-tension wound, a third layer is applied after the first and second layers are allowed to set and polymerize. The third layer is at least about 2.5 mm (0.0984 in.) wide and is substantially perpendicular to the first and second layers. The third layer may occur intermittently every 2.5 cm (0.984 in.) over the length of the wound, and preferably extends at least about 5 mm (0.197 in.) beyond the edge of the first layer.
