Problems solved by technology

The disadvantage of this method is: due to the small electrode body, it is very troublesome to replace the water-absorbing material, gauze and rubber ring, especially when there are many patients, there is no time to replace them one by one, and it is impossible to replace them one by one, which is easy to cause infection. Cross-infection is more likely to occur in patients with trauma
[0010] C. The connection between the traditional brain electrode support plate and the electrode beam is realized through the movable bolt, but the movable bolt can only use the supporting plate to move in a certain angle with the movable bolt as the center of the circle. In actual use, the moving direction of the supporting plate It moves in any direction with the change of head shape of different patients, which leads to poor auxiliary electrode fixation
[0011] D. Traditional brain electrodes can only be applied to EEG caps made of soft materials (hard materials can easily cause the placed brain electrodes to fall off when adjusting the position of the brain electrodes, making it more difficult for doctors to work), so they cannot Suitable for automatic EEG caps made of hard materials

Embodiment 1

[0050] Embodiment one: see figure 1 , Figure 5 , Figure 6 , Figure 7 , in the figure, brain electrodes for brain wave monitoring

[0051] Used as a dry electrode, the brain electrode contains an electrode body 11, a vertically arranged electrode rod 1, an adjustment nut 2, an electrode rod spring 3, a fixing bolt 4, and an electrode fixing block 5; the upper surface 6 of the electrode fixing block 5 is provided with A step through hole 7 for installing the electrode rod 1, the upper and lower parts of the inner wall of the step through hole 7 are respectively provided with an upper step 701 and a lower step 702, the upper step 701 is an inverted step, and the lower step 702 is a positive step. The electrode body 11 Connected to the lower end of the electrode rod 1, the electrode rod spring 3 is set on the electrode rod 1, the outer surface of the electrode rod 1 is provided with threads, the adjusting nut 2 is installed on the upper part of the electrode rod 1 through th...

Embodiment 2

[0069] Embodiment two: see figure 2 , Figure 5 , Figure 6 , Figure 7 , the numbers in the figure are the same as those in Embodiment 1, the representative meanings are the same, and the working process is basically the same, and the same parts will not be repeated. The outer surface of the lower part of the body 11 is wrapped with a liquid-absorbing layer 29 made of liquid-absorbing material, and the liquid-absorbing layer 29 also extends to the inside of the electrode body 11 through the lower opening 18, and the electrode contact head 19 protrudes from the liquid-absorbing layer 29 .

[0070] The liquid-absorbing material is sponge or cotton; the liquid-absorbing layer 29 is used to absorb the conductive liquid, and the conductive liquid is injected from the liquid injection hole 20; the liquid-absorbing layer 29 having absorbed the conductive liquid increases the contact area between the electrode body 11 and the scalp, The contact between the electrode body 11 and ...

Embodiment 3

[0073] Embodiment three: see image 3 , Figure 5 , Figure 6 , Figure 7 , the numbers in the figure are the same as those in Embodiment 1, the representative meanings are the same, and the working process is basically the same, and the same parts will not be repeated. The top of the contact head 19 is installed in the contact head installation hole 24 on the periphery of the lower surface of the electrode body 11. The contact head installation hole 24 is a stepped hole with a large upper part and a smaller lower part. The upper part of the electrode contact head 19 is installed in the lower small hole 241 of the stepped hole. Among them, the contact stopper 25 on the upper end of the electrode contact head 19 is blocked at the step of the step hole, and the contact spring 26 is installed in the large hole 242 on the top of the step hole. The upper opening of the large hole 242 is closed, and the contact spring The outer diameter of 26 is smaller than the outer diameter of...

Abstract

The invention relates to a brain electrode for monitoring brainwaves. The brain electrode comprises an electrode body, a vertically arranged electrode rod, an adjusting nut, an electrode rod spring and an electrode fixing block, wherein a step through hole for an installation of the electrode rod is formed in the upper surface of the electrode fixing block; the upper part and the lower part of the inner wall of the step through hole are provided with an upper step and the lower step in respective; the electrode body is connected with the lower end of the electrode rod; the electrode rod spring sleeves the electrode rod; the adjusting nut is arranged on the upper part of the electrode rod via a thread; a first spacing member outwardly projected is arranged on the external side surface of the lower part of the electrode rod; the electrode rod spring and the first spacing member are blocked between the upper step and the lower step; a bolt hole is formed in the upper surface of the electrode fixing block; a transverse electrode fixing installation groove is formed in the side surface of the electrode fixing block; the bolt hole communicates with the interior of the electrode fixing installation groove; and a fixing bolt is installed in the bolt hole. The brain electrode for monitoring brainwaves can be quickly detached and installed; the position can be flexibly and quickly adjusted; and reliable contact can be achieved between the brain electrode and the head part.

Description

technical field [0001] The invention relates to a brainwave monitoring device, in particular to a brain electrode for brainwave monitoring. Background technique [0002] Brain waves are formed by the sum of the synchronous post-synaptic potentials of a large number of neurons when the brain is active. It is the overall reflection of the electrophysiological activities of brain nerve cells on the surface of the cerebral cortex or scalp. The monitoring of brain waves has been widely used. in existing clinical practice. [0003] In traditional brainwave monitoring equipment, the wearing process of brain electrodes is very complicated, and the operation process is cumbersome and lengthy. Under normal circumstances, the patient should first wash his hair the day before the examination to remove the head oil; during the examination, first wear a special elastic cap on the head, and then use a comb to separate the hair where the brain electrodes are placed, exposing the scalp , w...
