The background technology is as follows:
electroencephalograms (EEG) are brain electrical signal waveforms detected and recorded by attaching several electrodes to the scalp according to a regular pattern. Electroencephalogram is important information for research and diagnosis of mental diseases at present, and non-invasive acquisition can be used for current electroencephalogram acquisition, and acquisition equipment is portable.
In order to ensure the quality of the electroencephalogram signals, the electroencephalogram electrodes are required to be contacted with the scalp as much as possible, and the impedance between the electroencephalogram electrodes and the scalp is reduced, so that better signals are obtained. In order to reduce the impedance, the connection is usually assisted by physiological saline or conductive paste. The wet electrode of the conductive paste wets hair by the manually injected conductive paste and leads the electrode and the scalp to form electric leads, although the effect is excellent, each time the conductive paste is manually injected one by one, the time and the labor are wasted, and the residue of the conductive paste after the electroencephalogram collection is finished brings inconvenience in cleaning and maintenance. The traditional saline electrode electroencephalogram cap needs to be soaked in normal saline, and although the impedance between the electrode and the scalp is low, the electrode and the scalp are wet, so that a subject is uncomfortable, the influence of electroencephalogram signals is brought, and the damage caused by short circuit is easier. In addition, physiological saline is gradually dried up, resulting in a gradual increase in impedance during the collection process. Therefore, a new product is needed to solve the above problems.
The utility model comprises the following steps:
the utility model aims to provide an electroencephalogram electrode fluid infusion device which can reduce impedance between scalp and an electroencephalogram electrode and improve comfort of a user.
In order to achieve the above object, the present utility model provides an electroencephalogram electrode fluid infusion device, comprising: the liquid storage bin, the liquid outlet bin and the plug body;

the plug body is movably arranged in the liquid outlet bin, and two ends of the plug body are respectively matched with the liquid inlet hole and the liquid outlet hole;
when the liquid outlet hole is in contact with the skin of a human body, the plug body seals the liquid inlet hole, and the liquid outlet hole is in an open state; when the liquid outlet hole is not contacted with the skin of the human body, the plug body seals the liquid outlet hole, and the liquid inlet hole is in an open state.
Further, the bolt body is provided with a sliding block which is in sliding connection with the inner wall of the liquid outlet bin.

As shown in fig. 1, the embodiment of the utility model provides an electroencephalogram electrode fluid infusion device, which can reduce the impedance between scalp and electroencephalogram electrode and improve the comfort of a user.
In order to achieve the above object, the present utility model provides an electroencephalogram electrode fluid infusion device, comprising: the liquid storage bin 1, the liquid outlet bin 2 and the plug body 3, wherein the liquid outlet bin 2 is provided with a liquid inlet hole 22 and a liquid outlet hole 21, and is communicated with the liquid storage bin 1 through the liquid inlet hole 22. The bolt body 3 is movably arranged in the liquid outlet bin 2, and two ends of the bolt body 3 are respectively matched with the liquid inlet hole 22 and the liquid outlet hole 21.

Compared with the prior art, the embodiment of the utility model is applied to the saline electrode, so that the problem of difficult cleaning after the conductive paste is used is avoided, and meanwhile, the saline supplementing amount can be accurately controlled through the matching of the liquid storage bin 1 and the plug body 3, so that the discomfort of a user caused by once supplementing excessive saline is avoided. Specifically, when the liquid outlet hole 21 is closed by the plug body 3, the liquid inlet hole 22 is in an open state, the brine in the liquid storage bin 1 flows into the liquid outlet bin 2 under the action of gravity, when the brine needs to be supplemented, the electroencephalogram electrode liquid supplementing device is pressed down, so that the plug body 3 moves towards the liquid inlet hole 22 under the extrusion of skin and closes the liquid inlet hole 22, meanwhile, the liquid outlet hole 21 is opened, the brine flows out to be in contact with the skin, the effect of reducing impedance is achieved, and because the liquid inlet hole 22 is closed by the plug body 3, the flowing brine just is the capacity of the liquid outlet bin 2, so that the discomfort of a wearer or the short-circuit fault of equipment caused by one-time injection of too much brine is avoided. In addition, after the skin no longer extrudes the plug body 3, the plug body 3 can close the liquid outlet hole 21 under the action of self gravity, and the liquid inlet hole 22 is opened again to supplement the salt water of the liquid outlet bin 2, and the reciprocating operation is very convenient.
