Blink monitor for detecting blink occurrence in a living subject
First Claim
1. A method of determining a patient condition including at least one of drowsiness and ocular disorder, the method comprising:
- receiving at least one signal from a sensor capable of detecting electrical activity in one or more muscles in a body of a person, the electrical activity being indicative of a blink occurrence;
determining which data from the at least one signal represents the blink occurrence; and
evaluating the blink occurrence data to determine an onset or actual occurrence of a patient condition, wherein the patient condition includes at least one of drowsiness and an ocular disorder.

Abstract
Embodiments of the present disclosure include a blink monitor for detecting blink occurrence in a living subject. For example, a blink sensor comprising a snap or tab electrode is positioned over one or more eye muscles known to assist in closing the eye. The electrode detects the electrical current in the muscle(s) and transmits a signal representative of the electrical current to a signal processing device. The device processes the signal to determine the occurrence of a blink, thereby producing an accurate blink electromyogram (EMG). The device and/or a caregiver may advantageously monitor the blink EMG, before and/or after occurrence processing, to determine the onset or actual occurrence of a patient condition. In an embodiment, the device monitors the blink EMG to determine the onset or occurrence of drowsiness in, for example, a driver, pilot, captain, doctor, soldier, or the like. In an embodiment, a caregiver monitors the blink EMG for one or more muscles in one or both eyes to determine the onset or occurrence of eye disease, such as, for example, strabismus.

11. A device for identifying a blink occurrence within a blink electromyogram (EMG), the device comprising:
-
an electrode pair configured to be positioned with respect to one or more muscles used to blink at least one eye in order to output a signal indicative of a changing biopotential associated with the one or more muscles; and
a processing device configured to receive the signal and identify blink occurrences within the signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

24. A monitor for monitoring the alertness of a person, the monitor comprising:
-
a receiver configured to receive data indicative of a blink electromyogram (EMG) of a person;
a processor configured to determine blink occurrences within the blink EMG and evaluate the blink occurrences to determine an onset or occurrence of diminished alertness; and
an alarm signal capable of activating an alarm configured to rectify the diminished alertness in the person. - View Dependent Claims (25, 26, 27, 28, 29)
