Description

A kind of electrode for encephalograms

Technical field

The present invention relates to a kind of electrode for encephalograms, particularly for electroencephalogram（Electroencephalography, EEG） The electrode for encephalograms of measurement.

Background technology

The electrode cap of current eeg measurement, generally using net, cloth material with certain elasticity, by electrode according to specific Position is fixed on cap.This kind of electrode cap design has the following disadvantages.

Wear complexity：Traditional EEG electrode caps under operator's auxiliary Jing Guo professional training, it is necessary to wear, and to electrode Middle injection conductive paste.The time that one veteran operator generally requires 40 ~ 60 minutes could complete wearing for electrode cap With adjustment, operating process is complicated, time-consuming.

Comfort level is low：Traditional EEG electrode caps can produce constriction due to the constraint of elastomeric material to user head, long Time can cause user head uncomfortable after.Meanwhile, conductive paste can make user's hair adhesion, for a long time using even meeting Caking, user needs to clean hair after completion of testing.

It can not be used under the conditions of daily life：Traditional EEG electrode caps are designed for the clinical application with scientific research, Because it wears complexity, liquid conduction cream use time is limited, the features such as cable winds complexity is inconvenient to carry, and causes it can not The convenient use under the conditions of daily life, strongly limit the application of EEG measuring.

The content of the invention

The purpose of this utility model is the brain electricity that providing one kind can conveniently wear in daily life, use for a long time Electrode.

The technical solution of the utility model is,

A kind of electrode for encephalograms, including：

Main body, it includes nose support and support, the head suitable for being worn on user；The nose support is suitable to essentially symmetrically wear Wear the nose in user, the support is suitable to be worn on after user two picks up the ears；

Reference electrode, it is arranged at the side of the nose support；

Grounding electrode, its be arranged at the nose support with the reference electrode relative opposite side substantially；

Signal electrode, it is arranged at the end of the support, and mastoid process is contacted after Shi Yuer is worn.

Preferably, the reference electrode, grounding electrode and signal electrode, are direct skin contact electrode.

Preferably, the material of the direct skin contact electrode is textile electrode or metal electrode.

Preferably, in addition to extension signal electrode；The extension signal electrode is by the electrode band that can be connected with the support Several signal electrode points are provided with composition, the electrode band；Extension signal electrode tie point is provided with the support.

Preferably, the support connects multiple extension signal electrode bands simultaneously.

Preferably, the extension signal electrode is non-direct contact electrode.

Preferably, the non-direct contact electrode includes：Wet electrode, capacitive electrode, conductive rubber, metal needle electrode Any one or more.

Each technical scheme more than, the present invention can obtain following technique effect.

1. wearing conveniently, the wear time of traditional electrode is substantially reduced, the complexity for wearing electrode process is reduced.

2. comfortable wearing, can for a long time use, not influence normal life.

3. signal electrode overlay area can monitor abundant cognitive psychological information, a variety of applications can be extended accordingly.

Embodiment

Such as accompanying drawing 1, the purpose of this utility model, which is to provide one kind, conveniently to be worn in daily life, use for a long time Electrode for encephalograms design, electrode includes the main body of an essentially glasses profile, main in the main body to include with lower component：

Reference electrode, it is generally disposed at Fig. 1 spectacles nose holders.In the electricity practice of existing brain, people used or The head of use and non-head reference electrode such as ear-lobe, neck and average reference electrode etc., each reference electrode is all to record Have a certain impact.However, the present inventor has found after relatively, reference electrode is arranged at spectacles nose holder can Obtain more preferable measurement effect.

Grounding electrode, it is generally disposed at Fig. 1 spectacles nose holders, essentially symmetrically positioned at the other side of reference electrode. Shown in Fig. 1 is a kind of non-limiting sample situation, and reference electrode can also be relative in Fig. 1 with ground electrode location Set with intercoursing.

Signal electrode, it is generally disposed at the stent ends of main body, and mastoid process is contacted after Shi Yuer is worn, equivalent to EEG TP9 P7 and TP10 P8 electrodes in ten-twenty electrode system, as shown in Figure 2.

Alternatively, in addition to extension signal electrode, it is made up of the electrode band that can be connected with main body rack.It is on electrode band Several signal electrode points.There are two extension signal electrode tie points on eyeglass holder, two extension signal electricity can be connected simultaneously Pole band.

Alternatively, the electrode material of above-mentioned various electrodes includes and direct skin contact electrode and non-direct contact electrode two Kind.

Reference electrode, grounding electrode and the signal electrode on glasses, are direct skin contact electrode, adoptable electrode Material has：Textile electrode, metal electrode.

Extension signal electrode is non-direct contact electrode, and multiple material can be used according to actual use situation as electrode, Including following species.

1）Wet electrode.

2）Capacitive electrode.

3）Conductive rubber.
