  • Apparatus for aspirating, irrigating and cleansing wounds
    Patent number: 9844474
    Abstract: An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

  • Wound closure device
    Patent number: 9844472
    Abstract: A wound dressing for use in the application of negative pressure to a wound, comprising a support member and a cover member positionable over the wound in use. The support member can have a first support element having a first portion aligned with a first axis and a body portion coupled with and extending away from the first portion, and a second support element having a first portion aligned with the first axis and a body portion coupled with and extending away from the first portion of the second support element. At least the body portion of each of the first support element and the second support element can be independently rotatable about the first axis. The support member can support at least a middle portion of the cover member above a surface of the wound so as to define a space between the wound cover and the wound.
