Patent No. EP3843679 (titled "Component Positioning And Encapsulation For Sensor Enabled Wound Dressings") was filed by Smith & Nephew on Aug 28, 2019. The application was issued on Dec 11, 2024.
A wound dressing with integrated sensors that monitor tissue health and transmit data to a caregiver. The dressing includes a flexible substrate with electronic components, tracks, and connectors, which are reinforced with a first coating. A second coating, which can be hydrophobic or hydrophilic, is applied to both sides of the substrate. The dressing can be used for negative pressure wound therapy, and the sensors can monitor parameters such as temperature, moisture, and tissue oxygenation.
