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.
Claims10
A portable brain monitoring system for determining a level of traumatic brain injury comprising:
- a disposable sensing system comprising an electrode array comprising 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, the at least two electrodes each having a signal, and sensing system electronics comprising 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 comprising an input channel for receiving the 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 based on the filtered signal;
- a monitoring system comprising monitoring system electronics further comprising at least one monitoring system electronic component, in wired or wireless communication with the sensing system electronics 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 of the subject based on EEG suppression of the transmitted signal or data, the monitoring system further comprising a display adapted for outputting the index of the level of traumatic brain injury;
- and
- a therapy system for providing treatment to the subject based on the level of traumatic brain injury of the subject,
- wherein the at least one sensing system electronic component further includes an analog to digital converter adapted for digitizing the filtered signal prior to transmission to the monitoring system.
A portable brain monitoring system for determining a level of traumatic brain injury and treating the injury comprising:
- a disposable sensing system comprising
- an electrode array comprising a flexible adhesive substrate and at least two electroencephalogram (EEG) electrodes affixed to or embedded in the flexible substrate, the at least two electrodes each having a signal, the electrode array adapted to be attached to the subject's forehead;
- electrode array electronics comprising at least one electronic component attached to the flexible substrate or integrated within the electrode array, the electrode array electronics comprising an input channel for receiving the signals from the at least two electrodes, at least one filter for removing noise or artifacts from the signals, an analog to digital converter for converting the filtered signals from analog to digital, a processor comprising an algorithm for quantifying at least a portion of the filtered digital signal and an output channel for transmitting the filtered digital signal and/or the quantified at least portion of the filtered digital signal or data based on the filtered digital signal and/or the quantified at least portion of the filtered digital signal;
- a monitoring system comprising monitoring system electronics further comprising at least one monitoring system electronic component, in wired or wireless communication with the electrode array electronics for receiving the transmitted filtered digital signal or data based on the filtered digital signal, and an algorithm for determining the level of traumatic brain injury of the subject based on EEG suppression of the transmitted signal or data, the monitoring system further comprising a display adapted for outputting the level of traumatic brain injury;
- and
- a therapy system for providing treatment to the subject based on the level of traumatic brain injury of the subject.
