Multi-conduction brain biological information feedback instrument

Abstract

A real-time electroencephalo-feedback training instrument based on Direct X3D by using 3D auditory-visual irritation as feedback measure is composed of multiple head skin electrodes, cerebroelectric signal sampling module, real-time cerebroelectric signal processing module, computer and relative software. Its advantages are high correctness of signals and simple operation.

Description

Technical field [0001] The invention relates to a medical auxiliary instrument, in particular to a real-time brain bioinformation feedback instrument, which can perform real-time processing of EEG signals, and is based on psychology and uses three-dimensional audiovisual stimulation as a multi-channel real-time feedback method. Brain biological information feedback device. Background technique [0002] Biofeedback technology was first developed based on Pavlov’s classical conditioning theory. Studies in Western countries in the past 40 years have found that the establishment of classic conditioned reflexes regulated by the central nervous system is not only effective for voluntary muscles, but also for visceral functions controlled by the autonomic nervous system, such as blood vessel and tracheal smooth muscle tension, and breathing. The rhythm of pulse, and even the shape and rhythm of EEG are equally effective. With the help of advanced equipment, throu...

Problems solved by technology

[0006] 1) A single electrode signal is used as the feedback information, and most of them are placed in the top area, which does not conform to the existing theoretical basis, cannot give full play to the greatest advantages of EEG biofeedback therapy, and is not very targeted;

[0007] 2) The instruments all use single frequency information as the feedback signal, the amount of information is relatively small, and the characteristics are not very clear, and the corresponding characteristic information for the patient cannot be obtained for feedback treatment;

[0008] 3) The feedback design is mainly based on plane games. The game is relatively simple, which cannot attract the attention of the subjects well and affect the results of the feedback treatment.

In addition, these instruments are all foreign brands, and the software is completely westernized, which is not suitable for China's national conditions. The operation is complicated and expensive, and there is no model suitable for home use.
