Publication number: 20230390101Abstract: An ostomy appliance comprising: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a connection member connected to the first wall for attaching the appliance to a user; an aperture located in either of the first and/or second walls for permitting waste gases to exit the appliance; and a multi-layer filter positioned adjacent and covering the aperture on an exterior surface of the respective first and/or second wall. A layer of the filter is hydrophobic and the hydrophobic layer is positioned directly adjacent the respective first and/or second wall. The hydrophobic layer has a first side and a second side, where the first side is connected directly to the respective first and/or second wall, and the connection holds the multi-layer filter relative to the wall.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Applicant: SALTS HEALTHCARE LIMITEDInventors: Kieran WILLIAMS, Lee TRETHEWAY, Iain POWNER, Jesus ALFARO, Marcus ALLEN
