Problems solved by technology

[0003] Most of the existing vagus nerve stimulators are implantable structures, and the installation process requires surgery, which is extremely inconvenient. The concha vagus nerve stimulator released by Ruishen Medical can stimulate the vagus nerve by wearing it outside the body. However, the vagus nerve stimulator uses The in-ear headphone structure is connected with a long headphone cable, which is inconvenient to carry and wear

Embodiment 1

[0038] refer to Figure 1 to Figure 4 , the bracket body includes a U-shaped bracket 10 and two sets of ear brackets 20 located at both ends of the U-shaped bracket 10, each end of the U-shaped bracket 10 is provided with a set of ear brackets 20 that are slidably inserted The socket 100 in the cavity 25, the U-shaped bracket 10 is telescopically connected with the ear bracket 20 through the socket 100, so that the size of the bracket body can be adjusted according to different individual head sizes; wherein, the socket 100 Matching with the contour of the inner cavity 25 of the ear bracket 20 , it provides a guiding function for the expansion and contraction between the U-shaped bracket 10 and the ear bracket 20 .

[0039]In addition, the lower end of the connector 100 is provided with a connecting shaft 102, the connecting shaft 102 is located in the inner cavity 25 of the ear bracket 20, and the cross-sectional profile of the connecting shaft 102 in the direction perpendicu...

Embodiment 2

[0048] Usually, different individuals have different head sizes. In the process of making adaptive adjustments to the size of the support body according to the head sizes of different individuals, if the length of the extension claws 22 cannot be adjusted, the coverage of the radially arranged extension claws 22 is inconvenient. For an individual with a small head, the sensing electrode 220 at the outer end of the extension claw 22 may not be able to effectively fit the skin of the human head, resulting in a drop in monitoring effect.

[0049] In order to solve the above problems, the extension claws 22 in the present invention are telescopic, that is, the coverage area of ​​the extension claws 22 arranged radially is adjustable, and the specific scheme is as follows:

[0050] refer to figure 2 The inner end of each set of extension claws 22 runs through the side wall of the cylinder seat 220, and the extension claws 22 are slidably installed in the side wall of the cylinder ...

Abstract

The invention provides a closed-loop percutaneous auricular concha vagal stimulator based on electroencephalogram signals. The closed-loop percutaneous auricular concha vagal stimulator comprises a support body, and further comprises an induction electrode, a stimulation electrode and a feedback control system which are arranged on the support body, wherein the induction electrode and the stimulation electrode are electrically connected with the feedback control system; and the support body comprises a U-shaped bracket and two groups of ear brackets arranged at two ends of the U-shaped bracket, a group of plug connectors which are slidably inserted into inner cavities of the ear brackets are arranged at the end part of each end of the U-shaped bracket, and the U-shaped bracket is telescopically connected with the ear brackets through the plug connectors. According to the closed-loop percutaneous auricular concha vagal stimulator based on the electroencephalogram signals, a U-shaped bracket structure is used, so the closed-loop percutaneous auricular concha vagal stimulator can be conveniently worn on the head of the human body; and meanwhile, the U-shaped bracket and the ear brackets are in telescopic connection, and the size of the support body can be flexibly adjusted according to the head size difference of different individuals, so better compatibility is obtained, and the wearing of the vagal stimulator is more convenient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a closed-loop percutaneous auricle vagus nerve stimulator based on electroencephalogram signals. Background technique [0002] Studies have shown that vagus nerve stimulation can be used to control and treat epileptic seizures, and the effect of seizure control can increase with the increase of treatment time; in addition, through vagus nerve stimulation of the brain, some patients will have emotions, The effect of improving wakefulness and memory can reduce the dosage of epilepsy drugs and improve the quality of life of epilepsy patients. [0003] Most of the existing vagus nerve stimulators are implantable structures, and the installation process requires surgery, which is extremely inconvenient. The concha vagus nerve stimulator released by Ruishen Medical can stimulate the vagus nerve by wearing it outside the body. However, the vagus nerve stimulator uses The in-ear headphone...
