EEG Headband with Improved Amplifier Attachment Shape Conformity, Electrode Placement, and Gel Delivery Functionality

An electroencephalography (EEG) headband apparatus comprising:

• a strap member configured to be removably attachable to a head of a patient;
• an amplifier device positioned on a first side of the strap member and comprising a plurality of amplifier device attachment members;
• a flexible backing member positioned on a second side of the strap member opposite the first side of the strap member and comprising a plurality of backing member attachment members configured to removably attach to the amplifier device attachment members to removably attach the amplifier device to the flexible backing member, thereby attaching the amplifier device and the flexible backing member to the strap member;
• and
• a plurality of electrode assemblies attached to the strap member;
• each electrode assembly of the plurality of electrode assemblies comprising:
• a capsule receiving structure;
• a stabilization structure comprising:
• a central attachment section;
• and
• a plurality of leg members positioned radially outward from a central axis of the electrode assembly;
• and
• a gel delivery structure configured to be positioned at least partially within the capsule receiving structure and to rotatably attach to the stabilization structure such that the gel delivery structure may be able to rotate independently of the stabilization structure, the gel delivery structure comprising:
• a plurality of teeth members configured to engage with and lacerate a lower surface of a gel capsule;
• and
• a plurality of gel delivery channels configured to deliver gel from the gel capsule to a skin surface of the head of the patient.

• an amplifier device attached to the strap member;
• and
• a plurality of electrode assemblies attached to the strap member;
• each electrode assembly of the plurality of electrode assemblies comprising:
• a capsule receiving structure comprising a threaded inner surface configured to engage with threads comprised by a gel capsule to facilitate positioning and attachment of the gel capsule to the capsule receiving structure;
• a stabilization structure comprising:
• a central attachment section;
• and
• a plurality of leg members positioned radially outward from a central axis of the electrode assembly;
• and
• a gel delivery structure configured to be positioned at least partially within the capsule receiving structure and to rotatably attach to the stabilization structure such that the gel delivery structure may be able to rotate independently of the stabilization structure, the gel delivery structure comprising:
• a plurality of teeth members configured to engage with and lacerate a lower surface of the gel capsule, comprising:
• a first tooth of the plurality of teeth members is configured to have a top point thereof at a first longitudinal position;
• and
• a second tooth of the plurality of teeth members is configured to have a top point thereof at a second longitudinal position, the first longitudinal position is such that the first tooth engages with the lower surface of the gel capsule before the second tooth;
• and
• a plurality of gel delivery channels configured to deliver gel from the gel capsule to a skin surface of the head of the patient;
• wherein rotation of the gel capsule causes translation of the gel capsule along a central axis of the electrode assembly, thereby causing the lower surface thereof to engage with the first tooth and subsequently engage with the second tooth as the gel capsule translates along the central axis.
