Patent ID: 10004415

Abstract:
An extended wear electrocardiography patch is provided. A flexible backing is formed of an elongated strip of stretchable spunlace material. A layer of stretchable adhesive is applied on at least a portion of a contact surface of the flexible backing, which defines a pair of openings on both ends. A non-stretchable circuit is axially affixed to an outward-facing surface of the flexible backing and has a pair of circuit traces. The flexible backing acts as a buffer between the non-stretchable circuit and the stretchable adhesive and prevents disadhesion of the flexible backing during bending. A pair of electrocardiographic electrodes are electrically coupled to each of the circuit traces. Conductive gel is provided in each of the openings and in electrical contact with the pair of electrocardiographic electrodes as the electrodes shift away from the openings in the flexible backing during the bending.
