Abstract
One embodiment provides a method, including: obtaining EEG data from one or more single channel EEG sensor worn by a user; classifying, using a processor, the EEG data as one of nominal and abnormal; and providing an indication associated with a classification of the EEG data. Other embodiments are described and claimed.
Core Innovation
The invention provides a system for continuously and remotely monitoring brain activity by using multiple self-contained, wireless, rechargeable, single channel EEG sensors configured to be positioned on a scalp of a patient and collect electroencephalogram (EEG) signals. Each sensor includes an equivalent orientation feature configured to correctly orient the sensor on the scalp. The system further uses computer-readable instructions that interact with the sensors to setup continuous EEG collection and to replace a sensor on the scalp.
Sensor setup and replacement are enabled by displaying locations on the scalp for positioning the sensors and different orientations of the equivalent orientation features relative to the associated locations, thereby allowing correct orientation of each sensor on the scalp. The sensors are removably adhered to the scalp with a plurality of adhesives that allow continuous collection of EEG signals through the adhesive, and are sufficient to allow replacement of the sensors on the scalp at least one time.
In another configuration, the invention uses four discrete, wireless, rechargeable, single channel sensors that are interchangeably positioned on a scalp and each include an orientation feature for correct placement. The system includes instructions that display, for each sensor, a location on the scalp and an orientation of the orientation feature relative to the location, allowing correct orientation, and then combine the EEG signals collected by the four sensors into a multi-channel montage.
The system uses a number of removable adhesives sufficient to allow continuous collection for multiple days including at least one replacement of each sensor on the scalp.
Claims Coverage
The partial content identifies two independent claims. Across the two independent claims, the coverage centers on continuous and remotely monitoring brain activity using multiple single-channel wireless rechargeable sensors with orientation-assisted setup, scalp adhesion enabling continuous collection, and sensor replacement with continuous monitoring over multiple days while forming a multi-channel montage.
Continuous and remotely monitoring brain activity with self-contained wireless rechargeable single-channel EEG sensors and orientation feature
A system for continuously and remotely monitoring brain activity comprising a plurality of self-contained, wireless, rechargeable, single channel sensors configured to be positioned on a scalp of a patient and collect electroencephalogram (EEG) signals of the patient, wherein each self-contained, wireless, rechargeable, single channel sensor includes an equivalent orientation feature configured to correctly orient the self-contained, wireless, rechargeable, single channel sensor on the scalp of the patient.
Setup and replacement of oriented scalp sensors via displayed placement and orientation
Non-transitory computer readable media storing first instructions that cause processors to interact with the plurality of self-contained, wireless, rechargeable, single channel sensors to setup the plurality of self-contained, wireless, rechargeable, single channel sensors for continuous collection of the EEG signals of the patient and replace a sensor of the plurality of self-contained, wireless, rechargeable, single channel sensors on the scalp of the patient, wherein setup and replacement comprise displaying locations on the scalp of the patient for positioning the plurality of self-contained, wireless, rechargeable, single channel sensors and different orientation of each of the equivalent orientation features with respect to an associated location on the scalp of the patient thereby allowing for correct orientation of each self-contained, wireless, rechargeable, single channel sensor on the scalp of the patient.
Removable scalp adhesives enabling continuous EEG collection through sensor replacement
A plurality of adhesives, wherein each adhesive is configured to removably adhere a sensor of the plurality of self-contained, wireless, rechargeable, single channel sensors to the scalp of the patient, and allow continuous collection of the EEG signals by the sensor through the adhesive, wherein the plurality of adhesives are sufficient to allow for replacement of the plurality of self-contained, wireless, rechargeable, single channel sensors on the scalp of the patient at least one time.
Four discrete interchangeably positioned wireless rechargeable single-channel sensors combined into a multi-channel montage
A system for continuously and remotely monitoring brain activity comprising four discrete, wireless, rechargeable, single channel sensors configured to be interchangeably positioned on a scalp of a patient and collect electroencephalogram (EEG) signals, wherein each discrete, wireless, rechargeable, single channel sensor includes an orientation feature configured to correctly orient the discrete, wireless, rechargeable, single channel sensor on the scalp of the patient, and wherein one or more non-transitory computer readable media storing first and second instructions cause processors to interact with the four discrete, wireless, rechargeable, single channel sensors to setup the four discrete, wireless, rechargeable, single channel sensors for continuous collection of the EEG signals of a patient and replace a sensor of the four discrete, wireless, rechargeable, single channel sensors on the scalp of the patient, wherein setup comprises displaying, for each discrete, wireless, rechargeable, single channel sensor, a location on the scalp of the patient for positioning the discrete, wireless, rechargeable, single channel sensor and an orientation of the orientation feature relative to the location thereby allowing for correct orientation, and combining the EEG signals collected by the four discrete, wireless, rechargeable, single channel sensors to form a multi-channel montage.
Removable adhesives sufficient for multiple days with replacement of each sensor
A plurality of removable adhesives, wherein each adhesive is configured to removably adhere a discrete, wireless, rechargeable, single channel sensor of the four discrete, wireless, rechargeable, single channel sensors to the scalp of the patient, and allow continuous collection of the EEG signals by the discrete, wireless, rechargeable, single channel sensor through the adhesive, wherein a number of adhesives in the plurality of removable adhesives is sufficient to allow the four discrete, wireless, rechargeable, single channel sensors to continuously collect EEG signals for multiple days including at least one replacement of each of the four discrete, wireless, rechargeable, single channel sensors on the scalp of the patient.
The identified independent claims are directed to continuous and remotely monitoring brain activity using multiple wireless rechargeable single-channel EEG sensors with orientation features. They require instruction-driven, display-based setup and sensor replacement on the scalp using removable adhesives that maintain continuous EEG signal collection, with the second configuration specifically combining four sensor signals into a multi-channel montage and enabling continuous collection across multiple days with replacement.
