Abstract:
An electroencephalograph (EEG) electrode locator assembly for use in combination with an EEG electrode locator headgear for accurate positioning of the EEG electrode locator assembly on the scalp of a user, the EEG electrode assembly comprising:an EEG electrode locator member adapted to be mounted to EEG electrode locator headgear; an EEG electrode received in and removably coupled with the EEG electrode locator member, so as to be removably electrically coupled to the EEG electrode locator headgear, the EEG electrode having an electrically conductive base for electrical communication with the scalp of a user for detecting EEG signals of the user; and a porous foam pad attached to the EEG electrode base, wherein the EEG electrode base includes a housing and a surface, the housing defining a chamber for containing and dispensing an electrically conductive gel, and the surface defining a lower gel dispenser opening for dispensing the electrically conductive gel; wherein the EEG electrode base has a surface defining a lower annular channel with an interior shoulder having a plurality of inwardly projecting tabs, and further comprising a bottom connector ring received in the lower annular channel of the EEG electrode base, the bottom connector ring having a plurality of slots corresponding to the inwardly projecting tabs of the EEG electrode base, for removably receiving and mating with the inwardly projecting tabs of the EEG electrode base, an annular groove being formed between the bottom connector ring and the housing of the EEG electrode base, an edge portion of the porous foam pad being removably received in the annular groove, whereby the porous foam pad is removably coupled to the EEG electrode base, and can be removed from the EEG electrode base and replaced by another porous foam pad by removing and replacing the bottom connector ring.
