Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Float electrode is placed on scalp at present, requires to do electrode adjustment every time, is based on this, the embodiment of the present invention mentions
The dry electrode of the telescopic brain wave acquisition of brain electricity cap and system of confession, it is possible to reduce the step of making electrode adjustment, to save the time, together
When reduce electrode pressure and give scalp bring feeling of pain.
To be adopted to the telescopic brain electricity of brain electricity cap disclosed in the embodiment of the present invention first convenient for understanding the present embodiment
Collect dry electrode to describe in detail.
Embodiment 1:
Fig. 1 is the main view of the dry electrode of the telescopic brain wave acquisition of brain electricity cap provided in an embodiment of the present invention.
Referring to Fig. 1, the dry electrode of the telescopic brain wave acquisition of brain electricity cap includes: shell 1, screw 2, nut 3, electrode 5 and spring
4；The top of screw 2 is plugged in nut 3, and the bottom of screw 2 is plugged in electrode 5, and spring 4 is fitted in the surrounding of nut 3；Bullet
The outside of spring 4 and the outside of electrode 5 are fixed with shell 1.
Specifically, above-mentioned electrode 5 is used to contact the contact surface of human body scalp, generally reacts corresponding with two electrodes 5
The neural electrical activity of brain area records the potential difference between two float electrodes.Screw 2, nut 3 and electrode 5, which can play, leads
Alive effect is conducting to external equipment by screw 2 and nut 3 when electrode 5 collects the signal on human body scalp；By
It in shell 1 under the action of spring 4, can move up and down, so protecting human body scalp from being compromised when pressure is excessive
Effect；Meanwhile the shell 1 can play fixed 5 position of electrode so that it will not convert easily, so, in the brain of different people
Cortex can make more electrode contacts touch human body scalp surface using the retractility of spring 4, it is made to contact scalp
The pressure on surface can achieve it is small as far as possible, also can be bigger to the protection of human body.Situations many in patient in this way does not have to every
The secondary position for all replacing electrode contact, can save more times.
The dry electrode of the telescopic brain wave acquisition of brain electricity cap provided in an embodiment of the present invention, the dry electricity of the telescopic brain wave acquisition of brain electricity cap
Pole includes: shell, screw, nut, multiple electrodes and spring；It is plugged in nut at the top of screw, the bottom of screw is plugged in
In electrode, spring is fitted in the surrounding of nut；The outside of spring and the outside of electrode are fixed with shell.By this way, it operates
Personnel reduce the step of making electrode adjustment, to save the time, while reducing electrode pressure and giving scalp bring feeling of pain.
Embodiment 2:
Fig. 2 is the top view of the dry electrode of the telescopic brain wave acquisition of brain electricity cap provided in an embodiment of the present invention.
Referring to fig. 2, the top of nut 3 is button shape, and bottom is groove-like；The bottom of nut 3 be made into groove-like be in order to
It can link together with the top of screw 2, so that they can be very good to be engaged togather, specifically, described in the present invention
Screw 2 and nut 3 are all customizations, allow to connect well；The top of nut 3 is made into button shape, convenient and outer
Portion's equipment (brain electricity cap) connection.The material of screw 2 and nut 3 be stainless steel material, stainless steel material include 304 stainless steels and
316 stainless steels, in the ingredient of two kinds of stainless steels, 316 stainless steels are more stronger than 304 stainless steel high temperature resistances, add molybdenum element
316 stainless steels can make 316 stainless steels obtain a kind of erosion-resisting special construction, in addition 316 stainless steels are mainly used for food
Industry and surgical apparatus；Since compared with 304 stainless steels, 316 stainless steels have better resisting chlorides corrosive power, so this
Screw 2 and nut 3 in invention select 316 stainless steel materials.
Fig. 3 is the perspective view of the dry electrode of the telescopic brain wave acquisition of brain electricity cap provided in an embodiment of the present invention.
Referring to Fig. 3, the top of electrode 5 is the round table-like of hollow out, so that the bottom of screw 2 can be inserted in the top of electrode 5；
It uniformly arranges multiple downwardly convex electrode contact heads the bottom of electrode, it can be seen that exemplary electrode contact head has 8 in figure
A, this is merely illustrative, and can formulate the number of electrode contact head according to the actual situation.Since silver chloride electrode is in high temperature
With the solubility of very little, high stability and reversibility in high pressure water solution system, and even if with the presence of hydrogen the case where
Lower electrode surface can also be protected well, these features are all that other electrodes are incomparable, therefore this electrode 5 selects chlorine
Change silver electrode.
Preferably due to the benefit of 316 stainless steels be described above, so the material selection 316 of spring 4 is stainless
Steel；Spring 4 is fitted in the surrounding of nut 3, and the outside of spring 4 and the outside of electrode 5 are fixed with shell；It is tower inside spring 4
, the position that such spring 4 can play fixed electrode 5 will not convert easily, can also not have in different cerebral cortexes
The position of electrode 5 is adjusted every time, and spring 4 can be such that shell 1 moves up and down, there can be more electrode contact heads to touch in this way
Scalp surface, so that the result of test is more accurate, also the adjustable pressure to scalp surface is to protect scalp surface.Specifically
Ground, the coefficient of elasticity of spring 4 are that preparatory test is good, spring 4 are all changed without testing every time, when so that operator saving
Between, the height of tower spring is 4mm, and upper radius is 2.5mm, and lower radius is 5mm, line footpath 0.6mm.
Further, shell 1 is preferably PC material, because PC (Polycarbonate, polycarbonate) is a kind of comprehensive
The excellent armorphous thermoplastic resin of energy, has excellent electrical insulating property, extensibility, dimensional stability and chemical corrosion resistance,
Higher intensity, heat resistance and cold resistance；Also have many advantages, such as self-extinguishment, fire-retardant, nontoxic, pigmentable, in addition with metal phase ratio, PC
Material weight is lighter, so that the present invention is unlikely to oppress scalp surface, mitigates the pressure to scalp surface.Shell 1 is cylinder
Body, height 10mm, diameter 13mm；Total height is 14.5mm.
Since the cerebral cortex of different people is different, so increasing its retractility using spring, make its electricity as much as possible
Pole contact head contacts scalp surface, while tower spring can be such that the pressure of contact surface reaches with the height of adjustable spring line footpath
It is as small as possible, play a protective role to human body also bigger, entire design for the ease of promoting electric conductivity, use silver chlorate with
Stainless steel mixed structure, as small as possible with constantly electrode weight, casing part uses PC plastic material.
In all examples being illustrated and described herein, any occurrence should be construed as merely illustratively, without
It is as limitation, therefore, other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
