Abstract

The invention provided herein relates to a wearable medical device and methods of use thereof for monitoring brain signals by electroencephalography technology in critically ill subjects suspected of having abnormal brain wave patterns including but not limited to electrographic seizures, spike and waves, periodic discharges and rhythmic delta activity.

Claims

1. A method of using an electroencephalography (EEG) device in a diagnostic manner on a subject by a user without adhering one or more electrodes to the subject, comprising:

providing a finger element for mounting on a finger of a user;

providing a sensor element on the finger element,

the sensor element being releasably applicable by the finger element to at least a contact surface of the subject,

the sensor element having at least an electrode for sensing EEG signals through the contact surface from the subject,

the sensor element being removable from the contact surface after sensing the EEG signals, and

the sensor element including at least a preamplifier component for processing the sensed EEG signals;

providing a signal-processing element apart from the finger element and operably connected to the sensor element for processing the sensed EEG signals received from the sensor element, and

providing an analysis and display element apart from the finger element and operably connected to the signal-processing element for receiving processed sensed EEG signals from the signal-processing element, for analyzing the processed sensed EEG signals, and for displaying analysis results,

whereby the EEG device is usable in a diagnostic manner by the user who uses the finger element to apply the sensor element to at least a contact surface of the subject for sensing the EEG signals of the subject and who also uses the finger element to remove the sensor element from the subject, the sensor element including at least a preamplifier component for processing the sensed EEG signals, which are transmitted to the signal-processing element apart from the finger element for processing, and to the analysis and display element for analyzing and display of the analyzed results.
