An injector system to inject a bolus of electrolyte into EEG electrodes includes a pressure pump containing electrolyte and a pen-like injector which is filled from the pump for the injection of a bolus for each EEG electrode. The injector includes a finger-operated plunger having a piston, an electrolyte chamber, a hollow shaft portion of the plunger, and a flexible bottom portion having flaps which are spread open by the injector head (end of the plunger).

Electrode electrolyte application device

In a brain wave detecting system, in one embodiment, a flexible hat is placed on the head of the patient. The hat contains a plurality of electrodes conforming to the hat. A circuit board having a low-noise integrated circuit amplifier may be mounted thereon. Each electrode uses a plurality of metal conductive fingers which protrude through the hair to the scalp and provide multi-contact sites on the scalp for each electrode. The tips of each electrode contact the user's scalp to provide a redundancy of contacts for each electrode.

Electrode system for brain wave detection

In a medical electroencephalographic EEG system, a hat is placed on the head of the patient. The hat contains a plurality of electrodes conforming to the hat. A circuit board having a low-noise integrated circuit amplifiers may be mounted thereon. In one embodiment each of the electrodes has a number of flexible and elastic fingers, for example 2-16 gum rubber fingers, having a conductive tip at the end of each finger, or flexible fingers made entirely of conductive material. In another embodiment the multi-contact electrode uses fingers which are rigid and connected to a spring-loaded plate. The tips contact the patient's scalp, without conductive gel or liquid, to provide a redundancy of contacts.
