Portable stimulating, awaking and evaluating system for disturbance of consciousness

Abstract

A portable stimulating, awaking and evaluating system for disturbance of consciousness comprises an EEG acquisition device, a signal preprocessing device which is connected with the EEG acquisition device and used for extracting an independent source component from a first EEG using an independent component analysis algorithm, a digital filter device which is connected with a signal preprocessing device and used for carrying out digital filter process on a second EEG using an empirical mode decomposition algorithm so as to extract an effective third EEG, a feature extracting device which is connected with the digital filter device and used for extracting frequency spectrum features, the sample entropy and the approximation entropy, a classification and a recognition device which is connected with the feature extracting device and used for classifying and recognizing disturbance of consciousness using a support vector machine according to the spectrum features, the sample entropy and the approximation entropy, and an output device which is used for outputting a stimulating signal through a stimulator. The portable stimulating, awaking and evaluating system for disturbance of consciousness is simple in structure and good in portability, and the portable stimulating, awaking and evaluating system for disturbance of consciousness can be used for families and communities using stimulation therapy on disturbance of consciousness.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a portable consciousness stimulation stimulation and evaluation system. Background technique [0002] Disturbance of consciousness is a clinically common disease after brain injury, especially in neurosurgery, emergency department and intensive care unit. Most of them are impaired perception of the surrounding environment caused by damage to the functional activities of the high-level nerve center of the brain. Severe disturbance of consciousness (commonly known as "vegetative state") manifests as coma. [0003] At the medical level, the judgment of the patient's state of consciousness mainly depends on the behavioral scale, which is subjective, and lacks practical wake-up promotion equipment and devices for evaluating the effectiveness of wake-up promotion. These scales are mainly scored by observing the behavioral performance of patients with impaired consciousness. For patients...

AI Technical Summary

Problems solved by technology

These scales are mainly scored by observing the behavioral performance of patients with impaired consciousness. For patients with impaired consciousness, the operational accuracy of behavioral judgment itself is not easy to guarantee, because the motor expression system that patients use to communicate may be damaged. At the same time, its arousal level can fluctuate very easily

Once there is a misjudgment of the state of consciousness, it will affect the doctor's correct prognosis of the patient

For conventional neuroimaging judgments such as MRI and CT, the evaluation of the degree of brain structural damage in disturbance of consciousness is indirect and incomplete
