Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an ear clip electrode for stimulating the vagus nerve. Background Technology

[0002] Neurostimulation therapy has been proven to be effective and safe for more than 20 neurological disorders, and is becoming a preferred treatment option. Stimulation of the vagus nerve can treat hypertension, diabetes, epilepsy, and other diseases, mainly because most internal organs are dually innervated and regulated by the vagus and sympathetic nerves. Chinese scholars have also discovered that stimulation of acupoints on the upper ear can treat hypertension and diabetes, which is closely related to the presence of the vagus nerve in the concha. The auricular branch of the vagus nerve in the concha is the only branch of the vagus nerve distributed to the surrounding skin; therefore, stimulating the auricular vagus nerve in this area can achieve the same effect as subcutaneous implantable neurostimulation therapy.

[0003] Therefore, ear-hook electrodes for stimulating the concha region of the vagus nerve have appeared on the market. These ear-hook electrodes achieve a fixed effect by hanging on the user's ear, but this wearing method is prone to slipping off and requires constant adjustment of the electrode position, making it impossible to accurately place the electrode in the concha region, resulting in a poor user experience.

[0020] Please refer to Figure 1 , Figure 1 This is a perspective view of an ear clip electrode for stimulating the vagus nerve. The present invention provides an ear clip electrode for stimulating the vagus nerve, comprising a first clamping assembly 1, a second clamping assembly 2, and an elastic member 3. One end of the first clamping assembly 1 is hinged to the second clamping assembly 2. One end of the first clamping assembly 1 forms a first electrode terminal 10, and one end of the second clamping assembly 2 forms a second electrode terminal 20. One end of the elastic member 3 abuts against the end of the first clamping assembly 1 away from the first electrode terminal 10, and the other end of the elastic member 3 abuts against the end of the second clamping assembly 2 away from the second electrode terminal 20.

[0021] The first clamping assembly 1 and the second clamping assembly 2 are elastically hinged together by an elastic element 3. In actual use, the ear clip electrode for stimulating the vagus nerve is connected to an external host, and then an electrolyte solution is sprayed onto the first electrode 10 and the second electrode 20, respectively. Next, by applying force to the first clamping assembly 1 and the second clamping assembly 2, they rotate relative to each other, causing the elastic element 3 to be compressed, while the first electrode 10 and the second electrode 20 move away from each other. At this point, the ear clip electrode for stimulating the vagus nerve is moved to the user's ear, so that the first electrode 10 contacts the cymba conchae region, and the second electrode 20 contacts the back of the triangular fossa of the user's ear. Then, when the force applied to the first clamping assembly 1 and the second clamping assembly 2 is removed, under the elastic force of the elastic element 3, the first clamping assembly 1 and the second clamping assembly 2 return to their original position, so that the first electrode 10 and the second electrode 20 are clamped in the user's ear, forming a closed circuit with the first clamping assembly 1, the user's ear, and the second clamping assembly 2. The external host generates a stimulation signal, which is sent to the first clamping component 1 through a wire. The first electrode 10 of the first clamping component 1 releases the stimulation signal to the user's concha region, thereby achieving a stimulation effect.

[0022] Thus, through the cooperation of the first clamping component 1, the second clamping component 2, and the elastic element 3, the first electrode 10 and the second electrode 20 are clamped onto the user's ear, achieving precise stimulation of the cymba conchae area. Furthermore, by adopting a clamping fixation method, the ear clip electrodes used to stimulate the vagus nerve are less likely to slip off, and the foreign body sensation is effectively reduced, greatly improving the user's experience.

[0023] Please refer to Figure 2 and Figure 3 , Figure 2 This is a cross-sectional view of an ear clip electrode used to stimulate the vagus nerve. Figure 3This is an exploded view of an ear clip electrode used to stimulate the vagus nerve. Further, the first clamping assembly 1 includes a first clamping member 11 and a first electrode 12. One end of the first electrode 12 is engaged with the first clamping member 11, and the other end of the first electrode 12 forms a first electrode terminal 10. The second clamping assembly 2 includes a second clamping member 21 and a second electrode 22. One end of the second electrode 22 is engaged with the second clamping member 21, and the other end of the second electrode 22 forms a second electrode terminal 20. The first clamping member 11 and the second clamping member 21 are hinged together. One end of an elastic member 3 is engaged with the end of the first clamping member 11 away from the first electrode 12, and the other end of the elastic member 3 is engaged with the end of the second clamping member 21 away from the second electrode 22.

[0024] In use, a force is applied to the first clamping member 11 and the second clamping member 21, compressing the elastic member 3 disposed between them. Simultaneously, the first clamping member 11 moves the first electrode 12, and the second clamping member 21 moves the second electrode 22, causing the first electrode terminal 10 and the second electrode terminal 20 to move away from each other. When the force applied to the first clamping member 11 and the second clamping member 21 is removed, the elastic member 3 returns to its original position under elastic force, causing the first clamping member 11 and the second clamping member 21 to return to their original positions. Thus, driven by the first clamping member 11 and the second clamping member 21, the first electrode terminal 10 and the second electrode terminal 20 move closer together.

[0025] In addition, the first clamping member 11 has a first wire-passing channel 113 and a first snap-fit ​​groove 114, with the first wire-passing channel 113 and the first snap-fit ​​groove 114 connected. One end of the first electrode 12 is snapped into the first snap-fit ​​groove 114, achieving a stable connection between the first clamping member 11 and the first electrode 12. In actual use, the connecting wire of the first clamping member 11 passes through the first wire-passing channel 113 and connects to the first electrode 12 in the first snap-fit ​​groove 114.

[0026] The second clamping member 21 has a second wire passage 213 and a second locking groove 214, with the second wire passage 213 and the second locking groove 214 connected. One end of the second electrode 22 is locked into the second locking groove 214 to achieve a stable connection between the second clamping member 21 and the second electrode 22. The connecting wire of the second clamping member 21 passes through the second wire passage 213 and then connects to the second electrode 22 in the second locking groove 214.

[0027] By providing a first wire passage 113 in the first clamping member 11 and a second wire passage 213 in the second clamping member 21, it is convenient for the first electrode 12 and the second electrode 22 to be connected to the connecting wire, and the connecting wire is protected.

[0028] Furthermore, the first clamping member 11 is L-shaped, and one end of the first electrode 12 is engaged with the first clamping member 11, so that the first electrode 12 extends toward the direction of the second clamping assembly 2.

[0029] In addition, in this example, both the first electrode 12 and the second electrode 22 are made of stainless steel, which makes it easy to wipe and clean the first electrode 12 and the second electrode 22, and also has good rust resistance.

[0030] Furthermore, the first clamping member 11 includes a first connecting portion 111 and a first hinge portion 112, with the first hinge portion 112 protruding from the inner side of the first connecting portion 111. One end of the first electrode 12 is connected to the first connecting portion 111. The second clamping member 21 includes a second connecting portion 211 and a second hinge portion 212, with the second hinge portion 212 located inside the second connecting portion 211, and one end of the second connecting portion 211 connected to the second connecting portion 211. The first hinge portion 112 and the second hinge portion 212 are rotatably connected. The elastic member 3 abuts between the first clamping member 11 and the second clamping member 21.

[0031] In this embodiment, the first hinge portion 112 and the second hinge portion 212 are respectively provided with connecting holes 200. A rotating connector 300 is used to pass through the connecting holes 200 of the first hinge portion 112 and the second hinge portion 212 in sequence, and then bolts are used to connect the rotating connector 300 to the first hinge portion 112 and the second hinge portion 212 by means of threaded connection. In this way, the first hinge portion 112 and the second hinge portion 212 are rotatably connected.

[0032] To improve slip resistance, anti-slip structures 100 are provided on the outer side of the first connecting part 111 and the outer side of the second connecting part 211, respectively, to prevent the surfaces of the first connecting part 111 and the second connecting part 211 from being too slippery and preventing the user from applying force to the first connecting part 111 and the second connecting part 211 normally.

[0033] To improve the stability of the elastic element 3, a first mounting groove 1110 is provided on the inner side of the first connecting part 111, and a second mounting groove 2110 is provided on the inner side of the second connecting part 211. During connection, one end of the elastic element 3 is engaged in the first mounting groove 1110, and the other end is engaged in the second mounting groove 2110 to prevent the elastic element 3 from falling off.

[0034] In addition, the end of the first electrode 12 forms a first electrode tip 10, which has an arc-shaped contact surface 101. When the ear clip electrode for stimulating the vagus nerve is clipped onto the user's ear, the arc-shaped contact surface 101 of the first electrode tip 10 contacts the concha sac region of the user's ear, effectively increasing the contact area between the first electrode 12 and the user's ear, and improving the wearing comfort of the ear clip electrode for stimulating the vagus nerve.

[0035] The second electrode 22 includes a connecting structure 221 and a contact structure 222. The contact structure 222 is connected to one end of the connecting structure 221, and the other end of the connecting structure 221 is connected to the second clamping member 21. The end of the contact structure 222 forms the second electrode tip 20, and the contact structure 222 is arc-shaped. When the ear clip electrode for stimulating the vagus nerve is clamped in the user's ear, the contact structure 222 contacts the back of the triangular fossa of the user's ear, and the arc-shaped design makes the contact part fit the user's ear more closely.

[0036] In summary, the first clamping component 1 and the second clamping component 2 are elastically hinged through the elastic element 3. One end of the first clamping component 1 forms the first electrode 10, and one end of the second clamping component 2 forms the second electrode 20. When the ear clip electrode for stimulating the vagus nerve is clamped on the user's ear, the first electrode 10 and the second electrode 20 make precise contact with the user's ear. Furthermore, by adopting a clamping fixation method, the ear clip electrode for stimulating the vagus nerve is not easy to slip off, and the foreign body sensation of wearing it is effectively reduced, which greatly improves the user's experience.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
