When, it is necessary to spend longer time, injection electrodes cream in the injection orifice into each electrode cap, so as to a certain extent to reality
The effect tested has a negative impact, such as the electrode cream injected at first can over time, and moisture content in electrode cream can be by
Gradually volatilize, so as to increase the contact impedance between scalp and electrode.
In addition, the improvement of people's living standards at any time, it is desirable to recorded at any time certainly using wearable Medical Devices
A kind of EEG signals of body, so as to the health of long-term monitoring itself, it is therefore desirable to electrode cap easy to use, can
Usage record EEG signals at any time.
Utility model content
The purpose of this utility model is the time of hand injection electrode cream when gathering EEG signals in the prior art to understand
It is long, and ordinary electrode cap is the problem of be not suitable for being applied in wearable device, it is proposed that a kind of automatic injection electrode cream
Novel electric polar cap.
The technical solution of the utility model is：A kind of Novel electric polar cap for automatically injecting electrode cream, including gas cell, inflation
Hole, rubber blanket and some activation plugs, some electrode cream memories, some electrodes；Air-filled pore, all work are provided with gas cell
Change plug to be fixedly connected with gas cell lower surface, activation plug, electrode cream memory and number of electrodes are equal and correspond, electricity
Pole cream memory is hollow cylindrical structure, and the corresponding activation plug of each electrode cream top of memory is flexibly connected, bottom
It is fixedly connected on the upper surface of rubber blanket, rubber blanket to be provided with some rubber blanket through holes, each electrode and is provided with electrode through hole,
Electrode through hole, rubber blanket through hole and electrode cream amount of memory it is equal and correspond, every group of corresponding electrode through hole, rubber
Pad and be interconnected between through hole and the hollow parts of electrode cream memory.
Preferably, activation plug is cylinder, and its basal diameter is equal to the internal diameter of electrode cream memory.
Preferably, activation plug is used as material using aluminium alloy or ceramics.
Preferably, electrode is used as material using Ag or AgCl.
The beneficial effects of the utility model are：

The electrode cream stored in device, can be disposably the synchronous injection electrodes cream of all electrodes, greatly shorten eeg signal acquisition
Time, while improving the degree of accuracy of gathered data.
(2) the utility model electrode structure is relatively easy, device entirety small volume and less weight, may apply to wearable device
In, improve it and use scope and application value.
Brief description of the drawings
A kind of novel electrode cap schematic diagram for automatic injection electrode cream that Fig. 1 provides for the utility model.
Description of reference numerals：1-gas cell, 2-activation plug, 3-air-filled pore, 4-electrode cream memory, 5-rubber blanket,
6-electrode.
Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
The utility model provide it is a kind of automatically inject electrode cream Novel electric polar cap, as shown in figure 1, including gas cell 1,
Air-filled pore 3, rubber blanket 5 and some activation plugs 2, some electrode cream memories 4, some electrodes 6.
Air-filled pore 3 is provided with gas cell 1, gas can be injected into gas cell 1 by air-filled pore 3 when using.
All activation plugs 2 are fixedly connected with the lower surface of gas cell 1.Activation plug 2, electrode cream memory 4 and electrode 6 are counted
Amount is equal and corresponds.Electrode cream memory 4 is hollow cylindrical structure, and each top of electrode cream memory 4 is corresponding
Activation plug 2 be flexibly connected, bottom is fixedly connected on the upper surface of rubber blanket 5.Activation plug 2 is cylinder, its basal diameter etc.
In the internal diameter of electrode cream memory 4, it so can effectively prevent that electrode cream overflows from the upper end of electrode cream memory 4 during extruding.
In the utility model embodiment, activation plug 2 uses aluminium alloy or ceramics as material, with light weight, the features such as wear-resisting, favorably
It is applied in the utility model in wearable device.
The effect of rubber blanket 5 is that in order that wearer is more comfortable, some rubber blanket through holes are provided with rubber blanket 5.
In the utility model embodiment, electrode 6 uses Ag or AgCl as material, can be by during eeg signal acquisition
DC skews are minimized, so as to improve the degree of accuracy of gathered data.Electrode through hole is provided with electrode 6, electrode through hole, rubber blanket lead to
Hole and the quantity of electrode cream memory 4 are equal and correspond, every group of corresponding electrode through hole, rubber blanket through hole and electrode cream
It is interconnected between the hollow parts of memory 4, the electrode cream so stored in the extruding bottom electrode cream memory 4 of activation plug is
It can be injected directly between electrode 6 and the scalp of wearer.
Concrete operating principle and process of the present utility model are as follows：
Before using the utility model collection EEG signals, appropriate electrode is stored in electrode cream memory 4 first
Cream, then the utility model is worn on to the head of user.Then, gas is injected into gas cell 1 by air-filled pore 3, with
Gas cell 1 is constantly inflated, and its internal pressure constantly increases, it will promote the extruding of activation plug 2 to be stored in electrode cream memory 4
In electrode cream, the electrode through hole of the rubber blanket through hole and electrode 6 that are passed to rubber blanket 5 is expelled to electrode 6 and wearer
Scalp between.
So due to each activation plug 2, extruding is stored in the electrode cream in counter electrode cream memory 4 simultaneously, just can be once
Property for the synchronous injection electrodes cream of all electrodes 6, greatly shorten the time of eeg signal acquisition, simultaneously because electrode cream
Synchronous injection, is not in, because moisture content volatilization causes the situation that contact impedance increases between electrode and scalp in electrode cream, to improve
The degree of accuracy of gathered data.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality
With new principle, it should be understood that protection domain of the present utility model is not limited to such especially statement and embodiment.
One of ordinary skill in the art can these technical inspirations according to disclosed in the utility model make and various do not depart from this practicality
New substantive other various specific deformations and combination, these deformations and combination are still in protection domain of the present utility model.
