Abstract

A disposable electrode patch for medical purposes comprises a flexible, elongated substrate with a first and a second surface, a first adhesive material disposed on a first adhesive area at a first end of the first surface, and a second adhesive material disposed on a second adhesive area at a second end of the first surface. Electrodes are arranged between the first and second adhesive areas on the first surface of the substrate. In use, the electrode patch is folded around a body part in such a way that the electrodes on the first surface make contact with the skin of the body part, while the first and second adhesive areas of the first surface are pinched together to form a stable assembly surrounding the body part.

Core Innovation

The invention relates to a disposable electrode patch for medical purposes having a flexible, elongated non-conductive substrate with a first and a second surface. A first adhesive material is disposed on a first adhesive area at a first end of the first surface, and a second adhesive material is disposed on a second adhesive area at a second end of the first surface. Multiple electrodes are arranged between the first and second adhesive areas so the patch can be folded around a body part such that the electrodes on the first surface make contact with the skin of the body part.

By folding the patch around the body part, the first and second adhesive areas of the first surface can be pinched together to form a stable assembly surrounding the body part. The electrodes comprise a counter current electrode, a measuring electrode, and a reference voltage electrode, which are arranged with their centers on opposite sides of a line parallel with the elongated substrate that intersects a center of the measuring electrode. Each of the counter current electrode, the measuring electrode and the reference voltage electrode has a substantially circular shape.

The patch is described for skin conductance monitoring of the autonomous nervous system for pain or awakening assessment, including use for neonates and preterm infants, particularly in a humid incubator environment. Embodiments include a defined region of the first surface that is adhesive-free except for the adhesive areas, optional foam substrate, and optional electrode paste covering the electrodes while not being applied to the adhesive areas.

Claims Coverage

The independent claim defines the core disposable, foldable electrode patch concept. It includes three inventive features: a foldable substrate with first and second adhesive areas that pinch together, a specific electrode set and positional relationship defined by a parallel line intersecting electrode centers, and substantially circular electrode shapes.

Overall, the claim coverage centers on the combination of a foldable patch stabilized by pinching first and second adhesive areas, a counter current/measuring/reference electrode set with a positional relationship defined by a parallel line intersecting the measuring electrode center and the other electrodes’ centers or areas, and substantially circular electrode geometries consistent with that line intersection.
