Abstract

The invention discloses an eyeball movement monitoring method. The method comprises the steps: receiving an output signal from a sensor, wherein the sensor is used for generating the output signal inresponse to eye movement; collecting the eyeball micro-tremor frequency of eyeball micro-tremor and the micro-scan amplitude of micro-scan from the output signal, and generating a frequency componentand an amplitude component according to the eyeball micro-tremor frequency and the micro-scan amplitude, wherein the frequency component includes the eyeball micro-tremor frequency, and the amplitudecomponent includes the micro-scan amplitude; and generating a combined data set from the frequency component and the amplitude component, wherein the combined data set includes the frequency component, the amplitude component and a time relationship between the frequency component and the amplitude component. The brainstem activities can be analyzed more comprehensively through data monitor of micro-scan, and finally a better analysis effect can be obtained.

Description

technical field [0001] The present invention relates to an eye movement sensor, system and method that displays a graphical and numerical representation of one or more fixative eye movements of a patient's eye (e.g., cornea / sclera) for a monitor (e.g., anesthesiologist, intensive care unit) The attending physician or clinician) provides an indication of the patient's brainstem activity or altered brainstem state, which includes his level of sedation response, awareness, and responsiveness. This can be used before, during and after medical or clinical procedures, for example, when anesthetizing a patient during surgery. The eye movement sensor is thin and compliant and can conform to the shape of the patient's closed eyelid or is located in the tissue fold of the patient's open eyelid, where it responds to fixative eye movements of the patient's eye. Background technique [0002] Anesthesia is administered to sedate and render a patient unconscious during the performance and...
