Patent number: 11896465Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a wound dressing, negative pressure source, user interface, sensor, and control circuitry. The user interface can receive an activation input. The sensor can detect whether the wound dressing is positioned over a wound. The control circuitry can cause supply of negative pressure in response to receipt of the activation input and a determination that the sensor detects that the wound dressing is positioned over the wound. In addition, the control circuitry can prevent supply of negative pressure in response to a determination that the sensor does not detect that the wound dressing is positioned over the wound.Type: GrantFiled: August 19, 2021Date of Patent: February 13, 2024Assignee: Smith & Nephew PLCInventors: Ben Alan Askem, Victoria Beadle, John Philip Gowans, Mark Hesketh, Allan Kenneth Frazer Grugeon Hunt, William Kelbie, Damyn Musgrave, Joseph William Robinson

WOUND TREATMENT APPARATUSES AND METHODS WITH NEGATIVE PRESSURE SOURCE INTEGRATED INTO WOUND DRESSING
Publication number: 20230320905Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment. In some embodiments, a negative pressure source is incorporated into a wound dressing apparatus so that the wound dressing and the negative pressure source are part of an integral or integrated wound dressing structure that applies the wound dressing and the negative pressure source simultaneously to a patient's wound. The negative pressure source and/or electronic components may be positioned between a wound contact layer and a cover layer of the wound dressing. The negative pressure source and/or electronic components may be separated and/or partitioned from an absorbent area of the dressing. A switch may be integrated with the wound dressing to control operation of the wound dressing apparatus. A connector may be direct air from an outlet of the negative pressure source to the environment. A non-return valve may inhibit back flow of air into the wound dressing.Type: ApplicationFiled: June 8, 2023Publication date: October 12, 2023Inventors: Ben Alan Askem, Victoria Beadle, John Philip Gowans, Mark Hesketh, Allan Kenneth Frazer Grugeon Hunt, William Kelbie, Damyn Musgrave, Joseph William Robinson -
