  • Patent number: 9713699
    Abstract: A device for transporting waste gases and liquid exudates from a wound. The device may include a multi lumen tubing and a connector for securing the multi lumen tubing to a fitting. The multi lumen tubing may include a double wall containment structure with a first lumen and a second lumen. The connector may include a body with a first cavity on one side, a second cavity on another side, and an interior wall located between the first cavity and the second cavity.

  • Publication number: 20160256638
    Abstract: A mobile dressing for delivering pressurized therapy gas to a wound. The dressing may include an inflatable structure for creating a sealed cavity around the wound. The inflatable structure further may include a dimple and an aperture within the dimple. A first lumen may be fluidly connected to the aperture for delivering pressurized therapy gas to the dimple. A second lumen may be fluidly connected to the opening for delivering pressurized gas to the inflatable structure. A first pump may include a first intake port fluidly connected to a first reservoir of therapy gas, as well as a first discharge port fluidly connected to the first lumen for supplying therapy gas at an increased pressure. A second pump may pressurize air for inflating the inflatable structure and creating a sealed cavity over the wound. Pressurized therapy gas may be administered to the wound in the sealed cavity.

  • Patent number: 8088113
    Abstract: A portable, self-contained device is described for the topical application of oxygen and the removal of wound exudates to promote the healing of skin wounds. The device includes a wound dressing that incorporates at least one electrochemical cell for generating oxygen. The device can regulate the supply of oxygen to the wound at various concentrations, pressures and dosages and is used to produce a high concentration of oxygen at the wound site. By reversing the polarity of the power source a reduced pressure can be created in a reservoir attached to our device. The reduced pressure in the reservoir draws naturally flowing exudates away from the wound. Alternately, two reverse polarity cells are used to alternately supply oxygen and draw away exudates.
