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

Publication number: 20230338650Abstract: Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.Type: ApplicationFiled: March 22, 2023Publication date: October 26, 2023Inventors: Julie Allen, Sarah Jenny Collinson, Edward Yerbury Hartwell, Derek Nicolini

Patent number: 11617823Abstract: 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: GrantFiled: June 21, 2019Date of Patent: April 4, 2023Assignee: Smith & Nephew PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Julian Lee-Webb, Derek Nicolini, Clare Green, Robin Paul Martin, Tina Michelle Walker
