Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.In the description of the present patent application, it is to be understood that term " on ", "lower", "front", "rear", "inner", "outside" etc., instruction
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, be merely for convenience of description the present invention and simplification retouch
It states, rather than the component of indication or suggestion meaning or structure must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it is not considered as limiting the invention.
As shown in Figures 1 to 9, electrode fixing device 100 provided in this embodiment, comprising: fixing seat 1 and vacuum chuck 2,
Fixing seat 1 is connected to the back side of vacuum chuck 2 and is partially project into the adsorption plane of vacuum chuck 2, and the vacuum that is located at of fixing seat 1 is inhaled
The end of 2 adsorption plane of disk is provided with fixing groove 131, electrode 200 be mounted in fixing groove 131 and with fixing groove 131
Sealing cooperation, it is ensured that the air-tightness of 2 adsorption plane of vacuum chuck guarantees that vacuum chuck 2 can still provide for negative pressure after installing electrode 200
Absorption.The connecting line 201 of electrode 200 passes through fixing seat 1 and extends to except the back side of vacuum chuck 2, to connect biography with equipment
The eeg signal that inspection is surveyed.And the distance of the outer end position of electrode 200 to 2 arc vertex of surface of vacuum chuck is less than to arcwall face
The distance at edge, the i.e. top for being located proximate to 2 arcwall face of vacuum chuck of electrode 200, avoid electrode 200 excessively protrusion and it is inconvenient
In the adsorption plane of vacuum chuck 2 and the Contact-sorption of brain skin.
Electrode 200 is mounted on fixation using the less feature of ewborn infant head hair by above-mentioned fixation device 100
On seat 1, the outer end face of electrode 200 is exposed to the adsorption plane of vacuum chuck 2 to coat conductive paste, passes through vacuum chuck 2 later
The absorption of fixing seat 1 equipped with electrode 200 is fixed to the head of baby, stablizing for electrode 200 is fixed to realize, baby head
Moving electrode 200 is shaken in portion will not shift and be detached from, and adapt to the EEG(electrocardiogram) examination demand of baby.
Although still may be imitated to the absorption of vacuum chuck 2 in view of newborn's head hair is rare in certain positions
Fruit adversely affects, and further to eliminate this influence, the present embodiment is evenly arranged on the adsorption plane of vacuum chuck 2
Multiple disk mouth diameters are not more than the secondary sucker 3 of 6mm, to form the multiple spot adsorption structure as octopus feeler, are passing through
While big vacuum chuck 2 adsorbs fixed, multiple small-sized secondary suckers 3 are also worked at the same time, and multiple spot works at the same time, and with big
Cover it is small, to eliminate the influence of hair all adsorption effects.
As shown in Figure 2 and Figure 7, the secondary sucker 3 in the present embodiment can also be subdivided into independent sucker 31 and linkage again
Sucker 32.Specifically, in the position by proximal edge of 2 adsorption plane of vacuum chuck equally distributed multiple secondary suckers 3 annular in shape
For independent sucker 31, other secondary suckers 3 in addition to independent sucker 31 are linked suction cup 32, the two the difference is that,

111 are connected to, and are provided in exhaust outlet 111 from air flue 21 to the check valve 4 of 111 one-way conduction of exhaust outlet, so as to form linkage
Sucker 32 and vacuum chuck 2 share the structure of a negative pressure cavity.Vacuum chuck 2 is squeezed to realize by 4 one-way exhaust of check valve
When to the negative-pressure adsorption on head, it is only necessary to effectively close in vacuum chuck 2 because of the structure of negative pressure cavity connection by primary extruding
When sealing label is attached, perhaps the linked suction cup 32 of whole is effectively sealed simultaneously when attaching or vacuum chuck 2 is inhaled with any number of linkages
When disk 32 effectively seals attaching simultaneously, it can guarantee the head that fixing seat 1 is firmly fixed to baby, and effect is powerful.
And the supplement that independent sucker 31 is adsorbed as the negative pressure cavity of aforementioned connection, each independent sucker 31 can be carried out independently
Negative-pressure adsorption, while extruding vacuum chuck 2 is adsorbed from the outside, any number of independent suckers 31 therein generate effective suction
It is attached, it can realize that absorption is fixed, even if the absorption of vacuum chuck 2 and linked suction cup is failed because of hair, only pass through the only of part
Vertical sucker 31 is also able to achieve effective fixation, even if the patients head dense in hair, is also able to achieve effective absorption and fixes, thorough
The influence of hair all adsorption effects is eliminated at bottom, guarantees to realize in any position on head to the accurate, stable fixed of electrode 200
Position.
