Abstract
A kind of EEG measurement electrode, it has hair claw, electrode slice, liftable electrode tie rod, liftable electrode tie rod snap close, hair claw spike, extendible elastic support, inflatable rubber tube.It utilizes telescopic elastic support and inflatable rubber tube to come automatic positioning and fixing electrode, electrode contacts with scalp automatically by means of hair claw, the inner chamber of liftable electrode tie rod is provided with reservoir, and the electrode imbibition body that it links to each other with electrode is communicated with, and electrode slice is contacted well with scalp.
Description
The invention belongs to the medical bio electric transducer
Eeg measurement electrode is the important sensing element that EEG signals is transmitted, and EEG signals is fainter, and it is easy to be subjected to the influence of factors such as fixed form of performance, electrode structure and the electrode of EEG measuring electrode.Therefore, the good eeg measurement electrode of research is one of important key of accurate recording EEG signals.Mostly adopt the silver-plated electrode of copper alloy of tubulose at present both at home and abroad, the last gauze ， And of its lower end bundle is soaked with sodium chloride brine and contacts with scalp.Because it is long to measure the used time of electroencephalogram, so the salt solution in the wet gauze is easy to volatile dry, makes electrode and scalp loose contact and introduces interfering signal.The cap that the fixed form of electrode mostly adopts rubber belt or rubber tube to make at present, because the size of the number of people is had nothing in common with each other, the number of people is not again the sphere shape of standard, it is more to add the used number of electrodes of EEG measuring, each electrode stressed even inadequately, often make the less electrode loose contact that partly is stressed, the correct record of EEG signals is affected.Simultaneously, length has hair on the scalp, by present electrode structure, all need push the hair of loading electrode position aside before loading electrode, cleans scalp, then the electrode that is soaked with conduction liquid is loaded onto, and each loading electrode all will spend a large amount of time and energy.The present invention improves at the problem of above-mentioned existence.
Accompanying drawing is the schematic diagram of EEG measurement electrode.
(1) hair claw among the figure; (2) electrode slice; (3) the imbibition body of electrode; (4) contact conductor; (5) plug of electrode; (6) liftable electrode tie rod; (7) snap close of liftable electrode tie rod; (8) notch of fore shaft; (9) lifting spring of liftable electrode tie rod; (10) housing of liftable electrode tie rod; (11) spike of hair claw; (12) electrode fixed support; (13) the support bracket fastened fixing hole of electrode; (14) inflatable rubber tube; (15) telescopic elastic support; (16) telescopic tube in the extendible elastic support; (17) the electrode lead-in wire that leads; (18) jack that leads and go between; (19) plug of total lead-in wire; (20) stop,threeway of gas tube; (21) elastic reducing-fixing band; (22) liftable electrode tie rod inner chamber reservoir.
Main points of the present invention are that eeg measurement electrode has: the snap close of hair claw, electrode slice, liftable electrode tie rod, liftable electrode tie rod, the lifting spring of liftable electrode tie rod, the spike of hair claw, inflatable rubber tube, telescopic elastic support.
Eeg measurement electrode device of the present invention be according to nineteen fifty-seven the 4th international electroencephalography and what is called 10～20% electrodes that can work out of clinical neurophysiology lay method.This method is earlier to measure from the nasion distance to occipital tuberosity (being called center line) and fall into distance by center line from the both sides preauricular pit with tape.Then from front to back (vertically) from left to right (laterally) each 10% and 20% distance lay electrode, in order to adapt to the adjustability of capitiform size, the present invention's vertical in laying the electrode slice device (promptly) and foundation ring, can be provided with telescopic elastic support (15), it can adopt the flexibility material with certain rigidity to make, can connect a telescopic elastic tube (16) between per two electrodes, when capitiform varied in size, the spacing between its electrode district can scaled or increase.This elastic tube can be made with spring or other elastomeric materials.Cause each electrode and the uneven contradiction of scalp contact force in order to overcome head aspheric surface body.Can add hollow inflatable rubber tube (14) at horizontal (promptly) and foundation ring, its effect is the contact force of reinforcing each electrode and scalp, simultaneously electrode is laterally being played positioning action.Electrode slice (2) but be to have the electrode imbibition body (3) of the conducting medium of degrease to contact with scalp by suction.For the ease of moving up and down of control electrode sheet (2), can be provided with the electrode tie rod (6) of lifting, the inner chamber of liftable electrode tie rod (6) can be provided with reservoir (22), the imbibition body that it can be connected with electrode slice is communicated with, conduction liquid can constantly be added in the imbibition body (3) of contact scalp, contact well with scalp to keep electrode.Electrode slice (2) can be by silver, the silver chlorate composite is once molding formed, and electrode slice (2) can not have plumb joint with contact conductor (4), and the kind electrode sheet has the advantage that electrode polarization is little, noise is low, electrode potential is stable.Electrode slice (2), imbibition body (3), contact conductor (4) can be contained on the liftable electrode tie rod (6), form one, liftable electrode tie rod housing (10) and the movable assembling of electrode fixed support (12).The Nei Qiang And that the lead-in wire of electrode (4) can pass liftable electrode tie rod is connected via the jack (18) of electrode plug (5) with the lead-in wire that leads, and can be provided with snap close (7) on the liftable electrode tie rod.Electrode is with before scalp contacts, can pin by the snap close on the lifting electrode tie rod (7), at this moment, electrode is in vacant state, in the housing (10) of liftable electrode tie rod, can be provided with spring (9), when electrode will be measured, can change certain angle to the snap close of liftable electrode tie rod, aligned notches (8) liftable electrode tie rod (6) just can be by the pressure of spring (9) electrode tie rod (6) toward pressing down, push hair claw (1) simultaneously open and push hair aside, electrode is contacted with scalp, in order not withstand scalp in the tip that makes hair claw (1), hair claw is other can be provided with hair claw spike (11), and it can make electrode be difficult for producing displacement simultaneously.Hair claw can be made by corrosion-resistant elastomeric material, can fuse with the electrode fixed support.Electrode fixed support (12) can be fixed on the extendible elastic support (15) by the support bracket fastened fixing hole of electrode (13), each electrode wire connecting can be passed through at elastic support (15) edge along the longitudinal, locate to leave a flexibility at each telescopic tube (16), avoid elastic support (15) to break electric wire when elongating or shortening or influence elasticity, the plug (19) that the lead-in wire that leads of each electrode can be aggregated into a total lead-in wire like this can the save operation time so that connect with the EEG instrument.The rubber tube (14) of inflation can be connected with the aerator of outside by the stop,threeway (20) of gas tube, stop,threeway (20) can be used to control inflation or venting, for fear of since when inflation electrode be subjected to displacement, can be provided with elastic reducing-fixing band (21) band at the chin place be hollow, can inflate.
This EEGelectrode can be within the specific limits by vary in size automatically location and push hair aside automatically of capitiform, reasonable in design, easy to use, electrode performance is good, distortion is little, can improve the eeg recording quality.
