Electrode array system for measuring electrophysiological signals
First Claim
1. An array of electrodes, including only four electrodes, for monitoring physiological electrical signals, said array comprising:
- a flexible body having a main portion, two satellite portions and a flexible connector connected between said main portion and each of said two satellite portions;
two electrodes of the four electrodes being positioned on said main portion and one electrode of the four electrodes being positioned on each of said two satellite portions.

Abstract
An array of electrodes is constructed to allow the user to easily adjust to the correct size of the patient'"'"'s head. The array is self-adhesive, pre-gelled and disposable. The array fits easily over the temple and forehead areas where EEG signals can be acquired by specially designed monitors for purposes of monitoring a number of bodily phenomena, including but not limited to, depth of anesthesia, and/or ischemia, and burst suppression. The array is connected to the monitor via a tab connector that is integral to the disposable device. The tab connector is insertible into a reusable connector that is part of a monitoring system.
