  • Publication number: 20100268180
    Abstract: A method and apparatus and an adapter device for testing the integrity of a dressing applied to a wound for the purpose of applying topical negative pressure therapy to that wound are described, the method comprising the steps of: applying a dressing to the wound so as to create a sealed cavity over the wound, the cavity having an aspiration conduit operably connected thereto for the purpose of creating a vacuum in the cavity; providing adapter device means to a liquid scalpel so as to create a substantially closed volume around a region in which a water jet exists in operation of the water scalpel; connecting a free end of the aspiration conduit to the closed volume formed by the adapter device means on the scalpel; and, using a vacuum created by a venturi effect of the liquid jet in the closed volume to create a vacuum in the dressing cavity.

  • Publication number: 20100211031
    Abstract: Apparatus (130) for use in wound therapy of mammals is described, the apparatus (130) comprising: a dressing covering the wound, the dressing being substantially sealed to prevent ingress of ambient atmospheric air to the wound; aspiration means (132) operably connected to a space between the dressing and the wound by an aspiration conduit (142) sealed to the point of entry between wound and dressing against ingress of ambient atmosphere, said conduit (142) being for aspiration of said wound and for removal of fluid from said space between said wound and said dressing; a waste container (148) for receiving aspirated fluid to be discarded operably connected to said aspiration conduit; and heating means (144) for heating said fluid in order to increase the vapour pressure thereof and to cause evaporation to reduce the volume of the fluid in the waste container (148). In a preferred embodiment of the present invention the waste fluid is also provided with a sparge gas.

  • Publication number: 20070167926
    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, and in which the cleansing means sits in the wound in use. The cleansing means (which may be a single-phase, e.g. micro-filtration, 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. Also, the dressing and a method of treatment using the apparatus.

  • Publication number: 20070141128
    Abstract: An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material 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.

  • Publication number: 20070129707
    Abstract: An apparatus for cleansing and promoting tissue growth in wounds, in which irrigant fluid optionally containing cell nutrients and/or other physiologically active material 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, a biodegradable scaffold in contact with the wound bed and a means for fluid cleansing and back to the dressing. The apparatus has means for supplying thermal energy to the fluid in the wound. The cleansing means (which may be a single-phase, e.g. micro-filtration, 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.

  • Publication number: 20060155260
    Abstract: An apparatus for cleansing wounds in which irrigant fluid from a reservoir (12) connected to a conformable wound dressing (3) and wound exudate from the dressing are recirculated by a device (18) for moving fluid through a flow path which passes through the dressing and a means (17) 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 mate rials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.
