Electrode device for amplitude-integrated electroencephalography

An electrode device for amplitude-integrated electroencephalography (aEEG) comprising:

• a housing mounted on an adhesive element to adhere the electrode device to a skin surface of a patient;
• an electrode plate placed in the housing at a certain distance from a support surface of the housing forming a hollow space;
• wherein the hollow space is configured to store an electroconductive gel between the electrode plate and the skin surface of a patient;
• and
• a wire connection for the electrode plate, said wire connection having a given length and comprising a proximal end and a distal end,
• wherein the housing comprises a first protruding part and a second protruding part, the first protruding part including a first hole, and the second protruding part including a second hole through which the proximal end of the wire connection is introduced and attached to the electrode plate,
• wherein the device further comprises a third protruding part that is symmetrically arranged with regard to the first protruding part,
• wherein the first protruding part is disposed in the housing inclined outwardly at an angle between 50-degree and 80-degree with respect to a contact surface of the electrode device,
• wherein the first hole has a conical-shaped geometry and is configured to periodically inject the electroconductive gel inside the hollow space by a pressure exerted by a blunt needle inserted into the first hole,
• wherein the third protruding part includes a conical-shaped hole configured to periodically drain and replace the electroconductive gel from the hollow space by the pressure exerted by the blunt needle, and
• wherein the housing comprises a shelf to sustain the electrode plate so that the first hole is connected to the hollow space and to the third hole.
