Description

Brain electricity cap
Technical field
The present invention relates to a kind of brain wave monitoring device, more particularly to a kind of brain electricity cap.
Background technology
Brain wave be brain in activity, what postsynaptic potential that a large amount of neurons synchronously occur was formed after summation, it It is overall reflection of the bioelectrical activity in cerebral cortex or scalp surface of cranial nerve cell, the monitoring of brain wave extensive utilization In existing clinical practice.
In traditional brain wave monitoring device, the wearing process of brain electrode is sufficiently complex, and operating process is loaded down with trivial details, tediously long.Typically In the case of, first have to make patient check the previous day hair washing, to remove head grease；During inspection, first special elastic cap is worn On head, then the hair for placing brain electrode position is separated with comb, exposure scalp, with 75% ethanol scalp to go Fat, brain electrode is then pressed into required position (such as bilateral volume, top, pillow, temples) and is clipped under elastic, and with pushing down head under brain electrode Hair, so just complete the installation of an electrode；Pressed after all brain electrodes install, then by the electrode holder on lead noseplate The order at the positions such as bilateral volume, top, pillow, temporo clips one by one, and it is noted that electrode holder puts order (by this after the completion of collection signal Reverse sequence presss from both sides back), so far patient's electroencephalographic electrode installation process side, which accuses, completes.General patient does conventional 16 and leads electroencephalogram 19 brain electrodes are installed, the more skilled operator of installation brain electrode typically uses 6-8 minutes, unskilled person with 10 minutes, 15-20 minutes even are arrived, whole operation process is very loaded down with trivial details, and easily gets position, the wrong electrode of folder, doctor's substantial amounts of time wrong Spend in the placement of brain electrode, operating efficiency is very low, and particularly in physical examination, person to be checked flocks together, and doctor is even more in a rush. Electrode holder is dismantled after finishing a electroencephalogram case history, wire intertwist can be made to exist when the order of dismounting is inconsistent with erection sequence Together, separated time at this moment will be removed with the substantial amounts of quality time, and wire can be usually pulled during separated time, if things go on like this The welding position fracture of brain electrode the end of a thread is easily caused, is checked so as to be delayed.Typically adopted in the connection of conducting wire and brain electrode With crocodile clip, but crocodile clip easily gets rusty, in order to not influence normal use, it is necessary to often change crocodile clip, this will result in The very big expense of hospital, wastes resource.
Traditional brain electricity cap is made of rubber strip elastic band, because of patient's head dummy individual difference, to pull adjustment electricity every time The size and shape of polar cap, it have impact on the operating efficiency of doctor；Moreover, can only be rough according to 10-20 rules when placing brain electrode Position Approximate is estimated, because everyone head dummy is inconsistent, it has not been convenient to go to measure with scale label, precise volume can not be accomplished to electrode Change and place, so that the figure collected is just not necessarily the correspondence position of system requirements, influence diagnosis effect.
The rubber strip of brain electricity cap or the service life of soft band are shorter, to certain time after just occur that pulling force is uneven and show As, cause that individual electrode contact is bad, and at this moment, doctor will adjust rubber strip, but influence whether again with good electrode, this Sample repeatedly adjusts, and wastes substantial amounts of Diagnostic Time, have impact on operating efficiency.
For doctor when removing brain electrode to patient, often one unclamps brain electricity cap rubber strip, and some electrodes will voluntarily drop To on the ground, the meeting also having is wrapped on patient's hair, causes unnecessary embarrassment, unnecessary trouble is also caused to patient.
Just need to wear earphone or sound equipment when patient carries out sound stimulation test, traditional earphone or sound equipment can only be had The patient of normal good hearing and ability of language expression uses, then helpless for deaf and dumb personnel；When flash of light stimulation test to be carried out When it is necessary to set up Flash lamps and lanternses at a distance, strong light equally also irritates medical personnel caused by Flash lamps and lanternses work, gives medical care people Member causes discomfort；The change of detection patients head's transient temperature is needed when doing Evoked ptential, at this moment can only be set with other auxiliary Standby operation, add the labor intensity of doctor.
When clinic needs high-definition picture to watch patient's each expression variations in detail during EEG signals are gathered When, traditional video brain electric equipment can only find out picture from the video of whole process video recording, because the image resolution ratio in video all compares The image resolution ratio directly taken pictures wants low more, causes the picture really wanting to see not clear enough, easily ignores variations in detail, make EEG research personnel are difficult to study.
The existing intracranial tissue blood oxygen that clinically detects is mainly that sensitive detection parts are placed on patient's forehead position to be detected, The encephalic blood oxygen detected is the oxygen content of blood of 3-4 cms in forehead, and can not judge the blood oxygen of whole encephalic comprehensively Content, greatly reduce encephalic feature and the accuracy of occupying lesion examination.

A, the installation of traditional brain electrode is to be pressed in using the traction force of flexible material on electrode crossbeam, allows electrode body and patient's scalp Contact, flexible material are usually to use netted cap made of rubber bar, and its service life is shorter, when its aging, rubber bar Drawing it is just uneven, cause the traction force to each brain electrode inconsistent, prevent some brain electrodes from fixing very well, and adjusting The influence of the brain electrode to fixing can be also caused in whole, wastes Diagnostic Time.Therefore, some producers are just by electrode crossbeam Neck make via into, installed with rubber bar on electrode via, although this method solves asking for brain electrode self falling Topic, but the problem of new is generated, after brain electricity cap is removed from patients head, brain electrode is still on brain electricity cap, it has not been convenient to right The keeping of brain electrode is more inconvenient to carry out chlorination experiment to brain electrode.
B, the electrode body portion of traditional brain electrode is typically provided with the hygroscopic material for being stained with conduction liquid（Such as cotton）, electrode body Outside encased with gauze, then be enclosed on elastic tape in electrode body, brain electrode is contacted by conduction liquid with scalp.This mode Shortcoming is：Because electrode body is smaller, change absorbent material, gauze and during elastic tape it is pretty troublesome, when particularly patient is more, do not have Time is changed one by one, does not accomplish that a people one changes more, infection is so also easy to produce, to there is the patient of wound more to produce cross-infection.
C, the connection of traditional brain electrode supporting plate and electrode crossbeam is realized by movable bolt, but movable bolt can only use support Plate makees movement in a curve by the center of circle of movable bolt in certain angle, and in actual use, the direction of motion of supporting plate is with different patients Any direction motion is made in the change of capitiform, so causes to fix auxiliary electrode well.
D, traditional brain electrode may be only available for brain electricity cap made of soft material（Hard material is in adjustment brain electrode position When, it is easy to allow the brain electrode placed to come off, cause working doctor difficulty to increase）, so hard material can not be used From the electric cap that beats one's brains made of material.
