OCULAR MICRO TREMOR (OMT) SENSOR, SYSTEM AND METHOD

摘要

An eye sensor, system and method for measuring fixational eye movements of an individual's eyeball (e.g., ocular microtremors and microsaccades) to provide a variable voltage biosignal for measuring the individual's brain stem activity. The eye sensor comprises a sensor mounted on the individual's closed or opened eyelid so as to be deflected by the fixational eye movements of the eyeball. A shielded flexible ribbon assembly supplies the biosignal generated by the sensor to an amplifier located on the individual's skin where the biosignal is amplified. The amplifier is interconnected with a signal processor and a display by which graphical and numerical representations of the biosignal are made accessible to an anesthesiologist, intensivist or clinician. A method for analyzing the biosignal to determine the brainstem activity of a patient.
