Abstract:
An appliance for collecting electroencephalographic signals from a patient's head, comprising:a. a flexible strap consisting of an anterior segment which is adapted to traverse longitudinally the crown of said patient's head and a plurality of posterior branch segments, each posterior branch segment projecting from the posterior end of the anterior segment at an angle to the center line of the anterior segment and being adapted to traverse therefrom portions of the rear of the patient's head, and each of the plurality of posterior branch segments incorporating a means for adjustment of length of said posterior branch segment,(1) each of the plurality of posterior branch segments extending from the posterior end of said anterior segment to an adhesive patch on which at least one receptor is mounted,(2) two of the plurality of posterior branch segments being adapted to be disposed symmetrically on either side of the patient's head so as to comprise two mastoid segments,(3) each of the at least one receptor on the adhesive patch of each of two mastoid segments comprising a mastoid receptor adapted to be placed in a predetermined anatomical position behind each of the patient's ears in the mastoid region;b. at the anterior end of said anterior segment, a frontal adhesive patch in which is mounted at least one receptor situated so that the at least one receptor may be placed in at least one predetermined anatomical position on the forehead of said patient;c. in the central and posterior portions of the anterior segment, at least one crown receptor mounted so that it may be placed in at least one predetermined anatomical position on the crown of the patient's head,d. a connector tab extending from said anterior segment to a connector; ande. electrical conductors contained in said strap so as to connect electrically each of the at least one receptor in the frontal adhesive patch, the at least one crown receptor, the mastoid receptors, and any other receptor with a corresponding contact in the connector so that independent signals may be transmitted from each receptor out of the appliance to external devices.
