Abstract
Disclosed systems include a self-contained electroencephalogram (EEG) recording patch comprising a first electrode, a second electrode and wherein the first and second electrodes cooperate to measure a skin-electrode impedance, a substrate containing circuitry for generating an EEG signal from the measured skin-electrode impedance, amplifying the EEG signal, digitizing the EEG signal, and retrievably storing the EGG signal. The patch also comprises a power source and an enclosure that houses the substrate, the power source, and the first and second electrodes in a unitary package.

An electroencephalogram (EEG) monitoring device comprising:
- a water-resistant unitary housing;
- a first electrode supported by a first electrode printed circuit board and a second electrode supported by a second electrode printed circuit board, the first and second electrodes being configured to be attached to a scalp of a patient and sense EEG signals;
- and
- a printed circuit board supporting a power source and a wireless transmitter configured to transmit the EEG signals,
- wherein the first and second electrode printed circuit boards are surface mounted to the printed circuit board and are supported by the printed circuit board and protrude from the printed circuit board,
- wherein the first electrode printed circuit board, the second electrode printed circuit board, and the printed circuit board are enclosed in the water-resistant unitary housing, and
- wherein surfaces of the first and second electrodes are exposed on a surface of the water-resistant unitary housing.
A system for electroencephalogram (EEG) monitoring comprising:
- an EEG monitoring device comprising:
- a water-resistant unitary housing;
- a first electrode supported by a first electrode printed circuit board and a second electrode supported by a second electrode printed circuit board, the first and second electrodes being configured to be attached to a scalp of a patient and sense EEG signals;
- and
- a printed circuit board supporting a power source and a wireless transmitter configured to transmit the EEG signals,
- wherein the first and second electrode printed circuit boards are surface mounted to the printed circuit board and are supported by the printed circuit board and protrude from the printed circuit board,
- wherein the first electrode printed circuit board, the second electrode printed circuit board, and the printed circuit board are enclosed in the water-resistant unitary housing, and
- wherein surfaces of the first and second electrodes are exposed on a surface of the water-resistant unitary housing;
- and
- a non-transitory computer readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to:
- determine a single channel EEG signals from the EEG signals received from the wireless transmitter using bipolar derivation;
- and
- analyze the single channel EEG signals to identify a seizure.
A method of operating a system for remote electroencephalogram (EEG) monitoring, the method comprising:
- collecting EEG signals with a first electrode supported by a first electrode printed circuit board and a second electrode supported by a second electrode printed circuit board, the first and second electrode printed circuit boards being surface mounted to a printed circuit board and being supported by and protruding from the printed circuit board, surfaces of the first and second electrodes being exposed on a surface of a housing that encloses the first electrode printed circuit board, the second electrode printed circuit board, and the printed circuit board, and the first and second electrodes being configured to be attached to a scalp of a patient;
- and
- transmitting the EEG signals with a wireless transmitter supported by the printed circuit board.
