Description

High-precision brain electrical signal detection device

Technical Field

The invention relates to a high-precision brain electrical signal detection device, belonging to medical instruments.

Background

Electroencephalograms, which are important physiological signals widely used in the medical field, are the overall reaction of electrophysiological activity of brain nerve cells on the surface of the cerebral cortex or scalp. The electroencephalogram signals contain a large amount of physiological and disease information, and the electroencephalogram signals are monitored and analyzed, so that diagnosis basis can be provided for certain brain diseases, and effective treatment means can be provided.

The electroencephalogram signal detection device which is commonly used at present is mainly an elastic adhesive tape mesh electroencephalogram cap. The electroencephalogram cap is composed of an elastic adhesive tape net structure. When the electroencephalogram head fixing device is used, a person manually puts an electrode on a preset motor base on an electroencephalogram cap, the electrode slipping phenomenon caused by the size of the head is easily caused by the electrode fixing mode, the position deviation of the electrode is large, the electrode is difficult to place at the correct position, and the accuracy of the acquired electroencephalogram signals is difficult to guarantee. And because the metal electrode is directly pressed on the scalp by the reticular rubber strip, the long-time measurement can cause strong oppression feeling and skin pricking feeling.

Therefore, a high-precision electroencephalogram signal detection device with high comfort level is needed.

the invention provides a high-precision electroencephalogram signal acquisition device with high comfort level, which comprises:

the flexible electrode array comprises 23 independent disc-shaped electrodes made of copper-silver chloride, the disc-shaped electrodes correspond to acupuncture points required to be detected for detecting brain waves with high precision respectively, and a cavity for containing a viscous conductive medium is arranged in the middle of each disc-shaped electrode;

and the data conduction module transmits the signals detected by the disc-shaped electrode to a terminal interface connected with external equipment through the conductive circuit and the DVI interface.

Preferably, different from the traditional brain electrode fixing mode, each disc-shaped electrode can be manually adjusted by the device, the brain signals of corresponding acupuncture points can be detected by each disc-shaped electrode, the electrode slippage phenomenon caused by the size of the head is prevented, and the accuracy of the collected brain signals is ensured.

Preferably, the disk-shaped electrode is made of copper plated with silver chloride, so that the disk-shaped electrode is good in conductivity and stable in signal.

Preferably, the circular cavity is arranged in the middle of the disc-shaped electrode, the contact area with the skin is small, and the oppression feeling and the skin pricking feeling brought to people in the long-time electroencephalogram signal detection and collection process can be reduced.

Preferably, the signal detected by the disk electrode is transmitted to a terminal interface connected with an external device through a conductive circuit and a DVI interface.

Has the advantages that: compared with the prior art, the brain electrode fixing device changes the traditional brain electrode fixing mode, can place each disc-shaped electrode on each corresponding acupuncture point, prevents the phenomenon that the electrode slips due to different head sizes of people to cause unstable contact of individual disc-shaped electrodes, can adjust the position of any single disc-shaped electrode, enables the positions of the disc-shaped electrodes on different head sizes to be more accurate, and improves the detection accuracy of brain signals. Compared with the operation mode that the metal electrode of the traditional electroencephalogram cap is directly pressed on the scalp by the mesh-shaped adhesive tape, the strong oppression feeling and skin pricking feeling caused by long-time measurement can be reduced.
