Publication number: 20170252496Abstract: An apparatus for cleansing wounds, in which wound exudate is removed from a wound bed and selectively cleansed and returned to the wound. The cleansing means 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 associated wound dressing and cleansing means are conformable to the wound, and may have irrigant fluid circulated from a reservoir 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.Type: ApplicationFiled: May 19, 2017Publication date: September 7, 2017Inventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Derek Nicolini, Tina Michelle Walker, Julian Lee-Webb

Publication number: 20170156967Abstract: An apparatus for cleansing wounds with means for stressing the wound bed and optionally tissue surrounding the wound, in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a devise 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. 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 means for stressing the wound bed and optionally tissue surrounding the wound promotes wound healing. The dressing and a method of treatment using the apparatus.Type: ApplicationFiled: November 29, 2016Publication date: June 8, 2017Inventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Julian Lee-Webb, Derek Nicolini, Clare Green, Robin Paul Martin, Tina Michelle Walker
