Abstract
The invention discloses a transcranial direct current stimulation instrument, which comprises a shell and surface electrodes, wherein a display screen and a key are arranged on the shell; a circuit board is arranged inside the shell; the surface electrodes are connected with the circuit board through a lead; a plurality of surface electrodes are included; each surface electrode comprises four cathode electrode plates and an anode electrode plate, wherein the anode electrode plate is arranged at the centre; the four cathode electrode plates are uniformly distributed around the anode electrode plate; the five electrode plates are round conductive rubber electrode plates; a fine sponge layer is arranged at the bottom surface of each electrode plate; the five electrode plates are arranged on a rubber pad at the same time, and the electrode plates are insulated with one another. The transcranial direct current stimulation instrument disclosed by the invention is rational in setting and convenient in use. Because the direction of the current is from an anode to a cathode, a stimulation focused at the centre and accurately positioned can be generated when an encephalic region is stimulated.
Description
Technical field
The present invention relates to a kind of armarium, particularly a kind of through cranium galvanic stimulation appearance.
Background technology
Of the prior art through the cranium galvanic stimulation appearance tDCS appearance part that comes with some shortcomings: 1, electric current mainly is distributed in the edge of electrode slice rather than focuses on the center; And many at present with 5 * 7cm, 5 * 5cm electrode slice, swash specific brain domain thereby can not accurately locate the ground deburring.2, when stimulating, thereby the normal saline in the foam-rubber cushion maybe too much or very few the inconsistent of resistance, the stimulus intensity instability of causing.3, when estimating the application of tDCS in certain disordered brain function, the treatment group continues tDCS to stimulate 20-30 minute, stimulated then stop to stimulate some seconds earlier and matched group is normal.The fiber crops when yet part treatment group patient can feel that tDCS stimulates, sensation such as itch, and the matched group patient did not just have this sensation after some seconds, the inconsistent and experimental result that can cause studying basic condition receives the influence of subjectivity.Be that so-called double-blind study is not realized real double blinding.4, the tDCS instrument is only established single a pair of stimulation at present, i.e. an anelectrode and a negative electrode.Yet the adjusting of many brain functioies relates to the neutral net in more than 1 brain district, needs 2 pairs or above electrode to stimulate simultaneously just to reach the adjustment of neutral net function and reinvents.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to prior art, provide a kind of structure setting more reasonable, can safety, focusing, multichannel ground stimulation brain function cortex through cranium galvanic stimulation appearance.
Technical problem to be solved by this invention is to realize through following technical scheme.The present invention is that a kind of it comprises housing and surface electrode through cranium galvanic stimulation appearance, and housing is provided with display screen and button; Be provided with circuit board in the housing; Surface electrode is connected with circuit board through lead, is characterized in: described surface electrode is several, and each surface electrode includes 4 negative electricity pole pieces and 1 positive electrical level sheet; In the middle of wherein the positive electrical pole piece was located at, 4 negative electricity pole pieces were around positive electrical pole piece uniform distribution; Described 5 electrode slices are circular conductive rubber electrode sheet, are provided with thin matter spongy layer in the bottom surface of electrode slice, and 5 electrode slices are located on the valve rubber simultaneously, and electrode slice insulate each other.
Of the present invention in cranium galvanic stimulation appearance technical scheme: the diameter of described electrode slice is preferably 8mm, and the thickness of thin matter spongy layer is preferably 5mm, and it is the square of 5 * 7cm that valve rubber is preferably size.
Of the present invention in cranium galvanic stimulation appearance technical scheme: described surface electrode is preferably 2-4.
Of the present invention in cranium galvanic stimulation appearance technical scheme: described circuit board is disclosed applicable to custom circuit plate of the present invention in can be for prior art.The optimal technical scheme of circuit board is: it comprises single-chip microcomputer, power amplifier, booster, constant-current source and AD transducer; Display screen is connected with AD converter through lead; Surface electrode is connected with constant-current source through lead; Constant-current source is connected with power amplifier, booster through lead; Power amplifier is connected with booster through lead, and button, AD converter, power amplifier, booster all are connected with single-chip microcomputer through lead.
Of the present invention in cranium galvanic stimulation appearance technical scheme: described circuit board can also comprise dermohygrometer, and dermohygrometer is connected with surface electrode, single-chip microcomputer through lead respectively; Said dermohygrometer is by resistance and the bridge type measuring circuit that the variable resistance polyphone is formed of 5 fixed values.
Of the present invention in cranium galvanic stimulation appearance technical scheme: described circuit board can also comprise trigger, and trigger is connected with single-chip microcomputer through lead.
Compared with prior art, the present invention of cranium galvanic stimulation appearance of the present invention and further design has the following advantages through cranium galvanic stimulation appearance:
One, being provided with rationally of surface electrode of the present invention, electrode slice is easy to use.Because sense of current flows to negative pole from positive pole, when stimulating certain brain district, can produce and focus on central authorities, pinpoint stimulation.Can accurately stimulate specified brain domain with locating, help exploring brain function and localized scientific research; Can be more safety with stably carry out the tDCS treatment; Can carry out the stimulation based on the brain function network of multi-path simultaneously, adjust corticocerebral function on the whole.
Two, tDCS of the present invention can carry out many to anelectrode, negative electrode output simultaneously.Can select 2 or a plurality of brain domain to stimulate simultaneously, thereby reach the integral body adjustment of brain function network.Patient for only needing single brain district to stimulate then can carry out multidigit patient's treatment simultaneously, has improved service efficiency.
Three, the present invention is through set dermohygrometer; The monitoring of dynamic skin resistance can be provided; Exceed certain limit alarm can be set, extrude too much normal saline or in time replenish normal saline, thereby keep the stable concordance that guarantees stimulus intensity of resistance.
Four, the present invention provides noise stimulation at random through set trigger, can cause fiber crops, the gargalesthesia of skin, makes the experimental subject stimulating group of can't distinguishing the true from the false, thereby realizes double blinding truly.
