Conscious disturbancecerebral cortex status detection system and method

Abstract

Theinvention discloses a conscious disturbancecerebral cortex status detection system, which comprises a brain response signalsynchronous collection module, a response signal noise processing module and a cerebral cortex status detection algorithmmodule. The response signalsynchronous collection moduleincludesatranscranial magnetic stimulationand magnetic-compatible EEG device, wherein an EEG capis a 64-channel high-density EEG cap,a transcranial magnetic stimulation coil is an 8-shaped coil. During implementation, the coil is arranged at the dorsolateral prefrontal areaof the left side of the patient(position of F3 electrode on the 10-20 EEG system) in a direction in which the magnetic field is perpendicular to the scalp. The conscious disturbancecerebral cortex status detection system and method fill the void of the conscious disturbancecerebral cortex status detection system and method. Compared with the current clinical research methods, the conscious disturbancecerebral cortex status detection system and method are cost-effective, convenient, simple in calculation, very applicable and suitable for clinical promotion.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and specifically relates to a method based on engineering and informatics, which is used for detecting the state characteristics of the cerebral cortex of patients with impaired consciousness. Background technique [0002] At present, there is basically no mature and reliable method for detecting the cortical state of disturbance of consciousness clinically. Individual cutting-edge medical research institutions have carried out the detection of cortical reactivity in disturbance of consciousness based on resting-state EEG, event-related potential and functional magnetic resonance technology. However, there are serious defects in the above methods, which restrict the application of these methods in clinical practice. The details are as follows: the existing detection methods based on resting-state EEG must be based on the statistical results of large samples, and cannot provide individualize...

AI Technical Summary

Problems solved by technology

However, patients with impaired consciousness generally have severe brain damage, and it is difficult to preserve the corresponding neural pathways. Therefore, the scope of application of this method in clinical practice is narrow.

Although functional magnetic resonance technology can give individualized judgments, it can only identify patients with particularly good cortical conditions based on the results, but cannot provide numerical indicators for doctors to refer to. Moreover, this method is complicated to operate and expensive, and cannot Popularized in clinical application

At present, foreign countries have reported that a method similar to the present invention is used to detect the cortical state of disturbance of consciousness, that is, the disturbance complexity index, but the algorithm is extremely complex and time-consuming, and it is difficult to promote it in clinical applications.
