Abstract

An EEG head harness for rapidly and automatically locating a plurality of EEG electrodes on the head of a patient in which the electrodes are removable and are spring biased toward the head of the patient and in which the electrode supporting frame is longitudinally separable.

Claims

1. An EEG head harness comprising:

a generally oval frame of electrically non-conducting material adapted to laterally encompass the head of a patient, said frame being longitudinally separable to facilitate the placing thereof on the head of the patient and including means for selectively limiting the longitudinal separation of said frame;

resilient means carried by said frame radially inward thereof adapted to pressurally engage the head of the patient;

a plurality of electrodes each adapted to electrically contact the head of the patient, each of said electrodes being removably carried individually by said frame by an electrically highly conductive spring means whereby each of said electrodes is spring biased to contact the head of the patient at a point displaced from the plane of the frame;

a plural lead connector; and

, plural conductor means carried by said frame for electrically connecting each of said highly conductive spring means individually to a lead of said plural lead connector.

2. The head harness of claim 1 wherein said electrically conducting spring means comprises an electrically highly conductive wire and wherein each of said wires differs in length from at least one other of said wires.

3. The head harness of claim 2 wherein said means for limiting the longitudinal separation of said frame includes a flexible strap secured at one end to one longitudinal portion of said frame and means carried by the other longitudinal portion of said frame adapted to selectively engage said strap intermediate the length thereof.

4. The head harness of claim 1 wherein said longitudinally separable frame includes right and left frame members;

and, wherein said means for selectively limiting the longitudinal separation of said frame includes spring means secured to said right and left frame members for biasing said frame members to a closed position.

5. An EEG head harness comprising:

a frame adapted to laterally encircle a human head;

a plurality of receptacles spaced around said lateral frame;

a plural lead connector;

plural conductor means carried by said frame electrically connecting each of said receptacles to one of the leads of said plural lead connector;

a plurality of plugs each selectively received in a selected one of said plurality of receptacles;

a plurality of electrodes; and

, an electrically conductive wire connecting each of said electrodes to one of said plurality of plugs whereby said electrodes may be connected to a selected lead in said plural lead connector by the insertion of the plug associated with that electrode into the one of said plurality of receptacles to which the selected lead is connected, said electrically conductive wire biasing the one of said electrodes associated therewith into position to contact the head encircled by said frame at a point displaced from the plane of the frame.

6. The head harness of claim 5 wherein the lengths of at least two of said wires differ significantly in length whereby different regions of the head may be electrically contacted by said electrodes.

7. The head harness of claim 9 wherein said frame is longitudinally split into two sections;

and, wherein said head harness further includes means for pivotably securing said two sections at one end thereof and means at the other end thereof for limiting the pivotable movement of said sections.
