Description
Technical Field
The invention relates to the field of biomedicine, in particular to an electroencephalogram signal acquisition device.
Background
In high performance aircraft, the pilot is subjected to excessive stress. The method is of great importance for monitoring the physiological state of pilots in real time, particularly accurately acquiring and monitoring signals such as electroencephalogram, eye blood flow, blood pressure, facial skin color change, respiration and the like in real time, and further acquiring abnormal signals in time, identifying risks and avoiding accidents.
In the traditional flight, the electroencephalogram detection system consists of two parts, namely a modified flight helmet provided with an electroencephalogram electrode and a recording system arranged in life-saving equipment. The helmet is cast according to the head model of the testee, the lining is detachable, and the helmet is installed by punching holes at the position corresponding to the scalp according to the number of electrodes to be installed. The electrode is needle-shaped, the needle bar is covered with a gold-plated electrode tip, and a special foam joint is covered on the needle tip.
The current intelligent helmet uses the sensor to contact with the user through conventional mounting means, for example, wear the brain electricity cap, directly fix the brain electricity electrode on the position with adhesive tape or gluing, or set up the ear clip on the ear, etc. However, these approaches are mostly ineffective in the working environment of pilots of high performance aircraft such as fighters and may even cause serious injury to the pilots. In addition, the existing electroencephalogram measuring device needs long preparation time for adjusting, applying conductive paste and the like before measurement, so that the existing intelligent physiological state monitoring sensor can not be basically used in the working environment of pilots.
In addition, the electroencephalogram monitoring device in the prior art mostly adopts disc-shaped electrodes or columnar electrodes, and one of the disc-shaped electrodes and the scalp have larger contact bottom surfaces, so thick hair cannot be avoided well, and further the disc-shaped electrodes and the scalp cannot be in tight contact, and the measurement effect is influenced; the columnar electrode, although having a smaller bottom surface than the disk electrode, still does not satisfy the degree of contact required for measurement; and secondly, the disc-shaped electrode or the columnar electrode needs to be repeatedly brushed or dipped with the conductive liquid before use, or the conductive paste is injected to the bottom end of the electrode by using an injector, before each use, the injector needs to be used for injecting the conductive paste one by one, and the use is very inconvenient.
Disclosure of Invention
In order to solve the problems and the defects of the prior art, the invention discloses a pilot electroencephalogram acquisition device which can elastically contact the scalp to carry out good electrical connection so as to accurately acquire electroencephalogram signals, does not need to consume long adjustment and preparation time, and is convenient and quick to use.
The invention relates to a novel electroencephalogram acquisition device with a superfine elastic bristle structure. The brain electrode array is fixed on a helmet of a pilot and used for collecting brain electrical signals, so that the purpose of early warning the health state of the pilot is achieved. The brain electrode bundle array is composed of 2 n-th power brain electrode bundles, and specifically can be 8-bundle, 16-bundle, 32-bundle, 64-bundle, 128-bundle and the like.
The brain electrode bundle is a superfine elastic conductive bristle bundle, the superfine elastic conductive bristle bundle is installed on the inner wall of the flight helmet, and the coverage area of the superfine elastic conductive bristle bundle is slightly larger than that of the traditional brain electrode collection site. The superfine elastic conductive bristle cluster is formed by combining a plurality of superfine elastic conductive bristles, an end cover is arranged at the top end of the superfine elastic conductive bristle cluster, and an electrode wire connected with the top end of the superfine elastic conductive bristle cluster is communicated to the outside from a hole in the end cover. The superfine elastic conductive bristle cluster is formed by combining 10-30 superfine elastic conductive bristles.
The superfine elastic conductive seta is a single brain electrode in the electroencephalogram signal detection device. The bottom end of the superfine elastic conductive bristle is in contact with the scalp and is in a circular end shape, a blind hole is formed in the center of the end from the bottom, a gas guide hole communicated with the outside is further formed in the blind hole, and conductive paste or conductive liquid is injected into the blind hole in advance before electroencephalogram detection is carried out. The top end of the superfine elastic conductive seta is connected with an electrode wire. The inner core of the superfine elastic conductive seta is made of spring steel, and the outer layer is plated with silver; the thickness of the coating is not more than 0.1mm, and the diameter of the bristle is not more than 0.5mm, so the conductive bristle is called as the superfine elastic conductive bristle.
After the electroencephalogram acquisition device is worn, the superfine setae automatically avoid hairs and are directly and tightly contacted with the scalp, and the conductive liquid or the conductive paste is directly adsorbed between the conductive setae and the scalp to form good electrical contact. One end of the bristle cluster far away from the scalp is connected with a flat brain electrode wire and is connected with a signal acquisition unit along the shape of the flying helmet. The electroencephalogram acquisition device is not only suitable for the conventional state, but also more suitable for the special state of pilot work.
One aspect of the present invention is advantageous in that in the technical solution of the present invention, the ultrafine bristles are used as a single electrode, which has certain flexibility and elasticity, and can naturally avoid hair and directly contact with scalp when in use, thereby greatly improving the accuracy of signal acquisition.
Another advantage of the present invention is that the ends of the ultrafine bristles of the present invention are provided with blind holes for receiving conductive liquid or paste. Before use, the whole brain electrode bundle (namely the superfine elastic bristle bundle) is dipped in a conductive paste or a conductive liquid container, so that the holes at the bottom end of each brain electrode are filled with the conductive liquid or the conductive paste, the use is convenient, and the time for adjustment and preparation is saved.
