Abstract
A system and method for using electroencephalographic (EEG) signals to monitor brain function, preferably detect occurrence of traumatic brain injury (TBI) to screen, assess, and potentially provide mitigating treatment to improve short and long term adverse outcomes of mild TBI (mTBI) and TBI. The system and method provides a readily available tool to assist in accurate and objective assessment of subjects with TBI, immediately at the point of injury (POI), during transportation, or upon arrival at a care facility, that preferably is applicable without advanced training or expertise.
Core Innovation
The invention relates to a portable brain monitoring system for determining a level of traumatic brain injury. The system includes a disposable sensing system having an electrode array with a flexible adhesive substrate and at least two electroencephalogram (EEG) electrodes affixed to or embedded in the flexible adhesive substrate, adapted to be applied to a subject’s forehead.
The disposable sensing system electronics include at least one sensing system electronic component attached to the flexible substrate or integrated within the electrode array. The at least one sensing system electronic component includes an input channel for receiving EEG signals from the at least two electrodes, at least one filter for removing noise or artifacts from the signals, and an output channel for transmitting the filtered signal or data.
A monitoring system receives the transmitted filtered signal or data in wired or wireless communication with the sensing system electronics. The monitoring system includes an algorithm for determining a numerical index or the level of traumatic brain injury based on EEG suppression of the transmitted signal or data, and a display adapted for outputting the index or the level. The system further includes a therapy system for providing treatment to the subject based on the determined level of traumatic brain injury.
Claims Coverage
The provided claim set covers three inventive features in a portable brain monitoring system that uses a disposable EEG electrode array, filters and transmits signals or data, determines a traumatic brain injury level based on EEG suppression, and outputs the result on a display, with a therapy system providing treatment based on the level.
Disposable electrode array on a forehead-adapted flexible adhesive substrate with onboard sensing electronics
A disposable sensing system comprising an electrode array having a flexible substrate and at least two electroencephalogram (EEG) electrodes affixed to or embedded in the flexible adhesive substrate adapted to be applied to a subject's forehead, with sensing system electronics comprising at least one sensing system electronic component attached to the flexible substrate or integrated within the electrode array, including an input channel, at least one filter for removing noise or artifacts, and an output channel for transmitting the filtered signal or data.
Numerical index determination from EEG suppression with display output
Monitoring system electronics in wired or wireless communication for receiving the transmitted filtered signal, or data based on the filtered signal, and an algorithm for determining a numerical index of the level of traumatic brain injury based on EEG suppression of the transmitted signal or data, with a display adapted for outputting the index.
Digitizing filtered signals prior to transmission via an analog to digital converter
The sensing system electronic component further includes an analog to digital converter adapted for digitizing the filtered signal prior to transmission to the monitoring system.
Across the independent claims, the core coverage is the use of a disposable, forehead-adapted flexible EEG electrode array with sensing electronics that filter noise or artifacts, transmission of filtered signal or data to monitoring electronics, determination of traumatic brain injury level or a numerical index using an algorithm based on EEG suppression, and display output, with a therapy system providing treatment based on the determined level.
Stated Advantages
Provides determination of a numerical index or the level of traumatic brain injury based on EEG suppression.
Outputs the determined index or level of traumatic brain injury on a display.
Provides treatment to the subject based on the level of traumatic brain injury.
Documented Applications
Fieldable/portable use as a brain monitoring system for determining a level of traumatic brain injury.
Use in a therapy system for providing treatment based on the determined level of traumatic brain injury.
