Publication number: 20150165101Abstract: 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: December 18, 2014Publication date: June 18, 2015Inventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Derek Nicolini, Tina Michelle Walker, Julian Lee-Webb

Publication number: 20150157508Abstract: 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. A biodegradable scaffold underlies the dressing on the wound bed to promote tissue growth. 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, an assembly comprising the dressing and scaffold, and a method of treatment using the apparatus.Type: ApplicationFiled: November 7, 2014Publication date: June 11, 2015Inventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Tina Michelle Walker, Julian Lee-Webb, Derek Nicolini, Robin Paul Martin
