Patent number: 11857746Abstract: 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: GrantFiled: August 31, 2020Date of Patent: January 2, 2024Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Derek Nicolini, Tina Michelle Walker, Julian Lee-Webb
