Patent No. EP3863575 (titled "Ostomy Appliance Having Conductive Ink Circuit For Leakage Detection") was filed by Hollister Incorporated on Oct 3, 2019. The application was issued on May 8, 2024.
An ostomy appliance with a conductive ink circuit for detecting leakage. The circuit is integrated into the appliance's skin barrier and detects changes in electrical resistance when the barrier's seal weakens, allowing fluid to escape. The appliance provides a notification to the user when leakage is detected, enabling early intervention to prevent exposure to the external environment.
