Patent number: 8882746Abstract: 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: GrantFiled: February 13, 2012Date of Patent: November 11, 2014Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Tina Michelle Walker, Julian Lee-Webb, Derek Nicolini, Robin Paul Martin

Patent number: 8834451Abstract: An apparatus for treating a wound can include a wound dressing, a vacuum pump configured to apply negative pressure to the dressing, and a fluid offtake tube configured to provide fluid communication between the pump and the dressing. The dressing can include a backing layer, a boss mounted to the backing layer at an opening in the backing layer, a foam layer on a proximal side of the backing layer, an adhesive on a periphery of the backing layer, and a membrane layer having a plurality of apertures configured to contact the wound. The foam layer can be in direct contact with the membrane layer, and can be configured to be simultaneously applied over the wound together with the backing layer. The adhesive can be configured to attach the backing layer to skin around the wound. The periphery of the backing layer can extend beyond and surround the membrane layer.Type: GrantFiled: January 31, 2012Date of Patent: September 16, 2014Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Tina Michelle Walker, Derek Nicolini, Julian Lee-Webb

Patent number: 8758313Abstract: An apparatus and method for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid, which may contain a physiologically active material, and wound exudate from the dressing are moved by a device for moving fluid through a flow path which passes through the dressing. A means for fluid cleansing may also be provided to recirculate fluid back to the dressing. 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 apparatus may also provide means for distributing such materials in a precise and time-controlled manner over the wound bed. It may also contain a means for providing simultaneous aspiration and irrigation of the wound.Type: GrantFiled: December 22, 2010Date of Patent: June 24, 2014Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Tina Michelle Walker, Julian Lee-Webb, Derek Nicolini, Clare Green, Robin Paul Martin

Patent number: 8348910Abstract: An apparatus (1) for cleansing wounds (5) in which irrigant fluid from a reservoir connected to a conformable wound dressing (2) and wound exudate from the dressing are moved by a device (18) (which may be a single pump or two pumps) for moving fluid through a flow path (6, 7, 9, 10) which passes through the dressing with a means for providing simultaneous aspiration and irrigation of the wound, and means for supplying thermal energy to the fluid in the wound. The former provides a desired balance of fluid at a controlled nominal flow rate that removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter maintains a temperature at the wound bed under the wound dressing at a level that promotes wound healing.Type: GrantFiled: April 27, 2005Date of Patent: January 8, 2013Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Edward Yerbury Hartwell, Julian Lee-Webb, Derek Nicolini, Clare Green, Robin Paul Martin
