Patent number: 12070544Abstract: A method and apparatus are disclosed for providing negative pressure at a wound site. The apparatus includes a suction pump for generating negative pressure, a negative pressure reservoir, a valve element arranged to selectively provide a fluid communication path between the reservoir and the wound site while a negative pressure in the negative pressure reservoir is greater than a threshold negative pressure, to thereby provide a desired negative pressure at the wound site, and wherein in response to a pressure in the negative pressure reservoir decreasing to the threshold negative pressure, the suction pump is operable to re-establish an initial negative pressure in the negative pressure reservoir.Type: GrantFiled: December 27, 2018Date of Patent: August 27, 2024Assignee: Smith & Nephew PLCInventor: Bryan Greener

Patent number: 11964093Abstract: A method and apparatus for providing negative pressure at a wound site. The apparatus includes a negative pressure reservoir and a reservoir valve for selectively connecting the reservoir to a wound chamber at a wound site. In particular, but not exclusively, the present invention relates to an apparatus including a source of negative pressure which acts as a negative pressure reservoir to continually or repeatedly “top up” an applied negative pressure so that negative pressure applied at a wound site can be maintained within desired limits for a relatively long period of time.Type: GrantFiled: July 3, 2019Date of Patent: April 23, 2024Assignee: Smith & Nephew PLCInventor: Bryan Greener

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

Patent number: 11766365Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a spacer layer with an upper portion and a lower portion. The spacer layer can be configured to be wrapped around at least one edge of the absorbent layer with the upper portion of the spacer layer being above the absorbent layer and the lower portion of the spacer layer being below the absorbent layer. In some embodiments, a negative pressure wound therapy apparatus can include a first and second spacer layer and an absorbent layer. The first spacer layer can be positioned below the absorbent layer and the first spacer layer can have a perimeter larger than a perimeter of the absorbent layer. The second spacer layer can be positioned above the absorbent layer. The second spacer layer can have a perimeter larger than the perimeter of the absorbent layer.Type: GrantFiled: June 20, 2022Date of Patent: September 26, 2023Assignee: Smith & Nephew PLCInventors: John Philip Gowans, Bryan Greener, Stephanie Jane Noble

Publication number: 20230240897Abstract: According to certain embodiments, an apparatus for applying negative pressure to a wound can include a negative pressure source, a sensor, and a controller. The negative pressure source can be configured to couple via a fluid flow path to a wound dressing and provide negative pressure to the wound dressing. The sensor can be configured to monitor a magnitude or frequency of pressure in the fluid flow path generated by the negative pressure source. The controller can be configured to determine an activity classification, such as breathing, changing positions while lying, sitting, walking, standing, jumping, traversing stairs, leg extending, leg bending, and performing chair squats, based on a change in the magnitude of pressure over time while the negative pressure source maintains the magnitude of pressure in the fluid flow path below a negative pressure threshold. The controller can output an indication of the activity classification.Type: ApplicationFiled: January 24, 2023Publication date: August 3, 2023Inventors: Bryan Greener, Edward Yerbury Hartwell, Felix Clarence Quintanar
