Electrode-integrated wound dressing with absorbent core
The patent US12070376B2 describes a novel wound dressing designed to enhance the monitoring and management of wound exudate. The dressing features a first adhesive layer for secure attachment to the skin, an absorbent core layer, and an electrode assembly that includes multiple electrodes arranged on the distal side of the absorbent core. This assembly is equipped with sensor points that allow for the detection of wound conditions. A first masking layer is strategically placed between the electrode assembly and the adhesive layer, containing openings that correspond to the sensor points, facilitating the passage of exudate to the electrodes for analysis. Additionally, a top layer is positioned on the distal side of the electrode assembly to provide further protection and functionality.
The electrode assembly is further detailed in the claims, indicating the presence of both first and second sets of electrodes, which can be printed on one or more support layers. The design allows for the formation of sensor points through the interaction of electrodes from both sets. The patent specifies that the spacing between sensor points can range from 3 mm to 20 mm, and the assembly may include additional layers, such as a spacing layer and a second masking layer, to optimize performance. The configuration aims to improve the wound dressing's ability to monitor exudate effectively, potentially leading to better wound care outcomes.
