Neurostimulation-based neurofeedback device using brain waves and heartbeat signals

A neurofeedback device comprising:

• a body configured to be attached to a user's skin and configured to provide electrical stimulation to a vagus nerve region of the user;
• a brain wave measure part configured to measure brain waves of the user;
• a genioglossus muscle stimulator;
• a first connection cable;
• and
• a second connection cable,
• wherein the body comprises:
• a frame provided in a symmetrical and elliptical shape and having a front surface, a back surface and a side surface, wherein a length of the frame in a first direction is shorter than a length of the frame in a second direction perpendicular to the first direction, the side surface has a first side and a second side opposite to the first side in the first direction, a third side and a forth side opposite to the third side in the second direction, and both the first side and the second side are concavely recessed toward a center, and the frame is configured to be attached to the user's neck,
• a vagus nerve stimulator located on the back surface of the frame, provided to comprise a plurality of electrodes for providing electrical stimulation to the vagus nerve region, and configured to be attached to the skin directly above the vagus nerve region located next to carotid artery of the user,
• a heart rate sensor located at a center of left and right symmetry of the frame on the back surface of the frame and configured to detect heart rates of the use,
• a manipulator located in the front surface of the frame and configured to receive a the user's command for controlling the brain wave measure part and the heart rate sensor,
• a plurality of connection ports formed on the side surface of the frame to transmit and receive signals, and
• a controller configured to generate a neurofeedback signal based on the brain waves of the user and the heart rates of the user,
• wherein the plurality of connection parts include a first port formed on the first side of the side surface and a second port formed on the third side of the side surface,
• wherein the genioglossus muscle stimulator is configured to be attached around the user's neck and configured to comprise an electrode for outputting electrical stimulation corresponding to the neurofeedback signal,
• wherein the first connection cable is configured to be connected to the first port of the plurality of connection ports to connect the body and the brain wave measure part to each other,
• wherein the second connection cable is configured to be connected to the second port of the plurality of connection ports and configured to connect the body and the genioglossus muscle stimulator to each other,
• wherein the plural electrodes of the vagus nerve stimulator are provided one by one on left and right sides in the symmetrical structure of the frame and, when the frame is configured to be attached to the user's skin, are disposed perpendicular to a direction of the vagus nerve, and
• wherein the plurality of electrodes of the vagus nerve simulator include a first electrode disposed on a left side of the back surface of the frame and a second electrode disposed on a right side of the back surface of the frame, and the first electrode and the second electrode are symmetrically arranged on the back surface of the frame with respect to the first direction, and the first electrode and the second electrode being arranged along the second direction.
