Electrode array
First Claim
1. An electrode array for measuring bio-potential signals from a skin surface, consisting essentially of:
- a pair of ear loops, each ear loop configured to fit around an ear of a human patient, and each ear loop further comprising at least one ear loop electrode;
a flexible web coupled between said pair of ear loops and supporting a plurality of electrodes thereon, said flexible web configured to span a forehead of said human patient, and said plurality of electrodes configured for placement against a skin surface on the forehead of said human patient;
wherein the ear loops and the flexible web are configured to retain the flexible web in tension across the forehead of said human patient and to position the plurality of electrodes operatively in place on the forehead when the pair of ear loops are secured about the ears of the human patient.

Abstract
A disposable electrode array 100, 200 including a flexible member 106, 206 in which a plurality of electrodes 102, 202 are disposed, having a shape adapted to contact the forehead skin surface on a human patient. A pair of ear loops 104, 204 coupled to the disposable electrode array 100, 200 secure the disposable electrode array 100, 200 about the patient'"'"'s ears, with the flexible member 106, 206 disposed across the patient'"'"'s bow, retaining the electrodes 102, 202 against the skin surface. Additional electrodes 102, 202 are disposed in proximity to the ear loops 104, 204 and are configured to contact the skin surface behind the patient'"'"'s ears. An auditory stimulus delivery element 116, 216 is coupled with each of the ear loops 104, 204, and positioned to seat in proximity to the patient'"'"'s ear canal for the delivery of auditory stimulus. Electrical conductors associated with the electrodes 102, 202 and the stimulus delivery elements 116, 216 are routed within the flexible member 106, 206 to a common external connection point 118, 218 for connection to an external system. The disposable electrode array 100, 200 may be configured for both evoking and measuring evoked bio-potentials in the human subject, or for measuring bio-potentials evoked using a separate stimulus delivery system.

14. A method for using an electrode array having a pair of ear loops and a flexible web coupled between said pair of ear loops, each ear loop configured to fit around an ear of a human patient and mounting at least one ear loop electrode, and the flexible web spanning a forehead of the human patient and supporting a plurality of electrodes thereon for placement against a skin surface on the forehead of the human patient, the method including the steps of:
-
securing a first ear loop in the pair of ear loops about an ear of the human patient, wherein said step of securing said first ear loop includes positioning the at least one ear loop electrode associated with the first ear loop; disposing the flexible web across the forehead of the human patient; and securing a second ear loop in the pair of ear loops about an opposite ear of the human patient, wherein said step of securing said second ear loop includes positioning the at least one ear loop electrode associated with the second ear loop; whereby the flexible member web is anchored across the forehead of the human patient and is retained in tension against the brow by tension between the pair of ear loops; and
wherebythe plurality of electrodes on the flexible web are operatively positioned on the forehead of the human patient. - View Dependent Claims (15, 16, 17)
