Description
Technical field
The present invention relates to a kind of brain wave monitoring device, more particularly to a kind of brain electrode for brain wave monitoring.
Background technology
Brain wave is brain in activity, what the postsynaptic potential that a large amount of neurons synchronously occur was formed after summation, it is overall reflection of the bioelectrical activity in cerebral cortex or scalp surface of cranial nerve cell, and the monitoring of brain wave has been widely used 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.Generally, first have to make patient check the previous day hair washing, to remove head grease；During inspection, first special elastic cap is worn on the head, then the hair for placing brain electrode position is separated with comb, exposure scalp, with 75% ethanol scalp with degreasing, then brain electrode is pressed into required position (such as bilateral volume, top, pillow, temples) to be clipped under elastic, and with hair is pushed down under brain electrode, so just completes the installation of an electrode；After all brain electrodes install, the electrode holder on lead noseplate is clipped one by one by the order at the positions such as bilateral volume, top, pillow, temporo again, and it is noted that electrode holder puts order (being pressed from both sides back after the completion of collection signal by this reverse sequence), so far patient's electroencephalographic electrode installation process side, which accuses, completes.General patient, which does conventional 16 and leads electroencephalogram, will install 19 brain electrodes, the more skilled operator of installation brain electrode typically uses 6-8 minutes, unskilled person is very loaded down with trivial details with 10 minutes, or even to 15-20 minutes, whole operation process, and easily get position, the wrong electrode of folder wrong, doctor is spent in the placement of brain electrode the substantial amounts of time, and operating efficiency is very low, 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; together with making wire intertwist when the order of dismounting is inconsistent with erection sequence; at this moment separated time 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 it is easy for causing the welding position of brain electrode the end of a thread to be broken, is checked so as to be delayed.Crocodile clip is typically used in the connection of conducting wire and brain electrode, 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, waste resource.
Traditional brain electricity cap is made of rubber strip elastic band, because of patient's head dummy individual difference, to be pulled the size and shape of adjustment electrode cap every time, be have impact on the operating efficiency of doctor；Moreover, can only be according to 10-20 rule rough estimate Position Approximates, because everyone head dummy is inconsistent when placing brain electrode, inconvenience goes to measure with scale label, it can not accomplish that precise quantification is placed to electrode, 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, the uneven phenomenon of pulling force just occurs after to certain time, cause individual electrode contact bad, at this moment, doctor will adjust rubber strip, but influence whether so repeatedly to adjust with good electrode again, substantial amounts of Diagnostic Time is wasted, 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 be dropped to voluntarily on the ground, and the meeting also having is wrapped on patient's hair, causes unnecessary embarrassment, unnecessary trouble is also caused to patient.
Following point be present in traditional brain electrode：
A, the installation of traditional brain electrode is to be pressed in using the traction force of flexible material on electrode crossbeam, electrode body is allowed to be contacted with patient's scalp, flexible material is usually to use netted cap made of rubber bar, its service life is shorter, and when its aging, the drawing of rubber bar is with regard to uneven, cause the traction force to each brain electrode inconsistent, prevent some brain electrodes from fixing very well, and the influence of the brain electrode to fixing can be also caused in adjustment, waste Diagnostic Time.Therefore, some producers just make the neck on electrode crossbeam into via, installed with rubber bar on electrode via, although this method solves the problems, such as brain electrode self falling, but the problem of new is generated, after brain electricity cap is removed from patients head, brain electrode is still on brain electricity cap, the inconvenient keeping to 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）, the outside of electrode body is encased with gauze, then is enclosed on elastic tape in electrode body, and brain electrode is contacted by conduction liquid with scalp.The shortcomings that this mode is：Because electrode body is smaller, change absorbent material, gauze and during elastic tape it is pretty troublesome, when particularly patient is more, changed one by one without the time, do 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 make movement in a curve as the center of circle using movable bolt using supporting plate in certain angle, in actual use, the direction of motion of supporting plate is to make what any direction moved with the change of different patient's capitiforms, 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 when adjusting brain electrode position, it is easy to allows the brain electrode placed to come off, increases working doctor difficulty）, so can not be applied to made of hard material from the electric cap that beats one's brains.
