Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a non-invasive ear vagus nerve stimulator. Background Art

[0002] The vagus nerve is the longest cranial nerve in the human body. It branches out to the internal organs, muscles, ears, etc. When these parts are stimulated, the sensation can be transmitted to the brain through the vagus nerve fibers. The brain also feeds back information to the internal organs through the vagus nerve to adjust the internal organs and achieve a balanced and stable state. A non-invasive ear vagus nerve stimulator refers to an external vagus nerve stimulator at the ear, which uses invisible electrical pulses to stimulate a branch near the vagus nerve, thereby activating the vagus nerve. It is often used to treat patients with epilepsy, cognitive impairment, anxiety and depression, migraine, sleep disorders and other diseases.

[0003] The existing ear vagus nerve stimulator includes a control host and a stimulator located outside the ear hole and stuck in the concha cavity through the tragus. The stimulator is connected to the control host through a data cable. The stimulator is provided with a stimulating electrode that fits at the position of the hymena concha, which is the best position for transauricular vagus nerve stimulation treatment in current research.

[0004] In order to ensure that the stimulator and the stimulating electrode can fit tightly in the concha area, the appearance of the stimulator and the stimulating electrode often needs to be larger than the volume of the concha area, so that they can be supported on the inner side of the concha area, facilitate the fixation of the position of the stimulator, and keep the stimulating electrode close to the inner wall of the concha. However, the stimulation treatment time is generally around 30 minutes and needs to be performed multiple times. Long-term wearing of a stimulator that stretches the concha area often causes ear tenderness in patients, which can affect the patient's subsequent treatment. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] See also Figure 2-Figure 5 A non-invasive ear vagus nerve stimulator comprises a control host 1 and a stimulator mechanism 2 arranged at the concha part, a data connection line 11 is connected between the control host 1 and the stimulator mechanism 2, an electrode mechanism 3 which fits the hymen of the concha is arranged on the stimulator mechanism 2, and a protruding discharge head 32 which fits the hymen of the concha is arranged on the surface of the electrode mechanism 3;

[0027] The stimulator mechanism 2 includes a stimulator body 21 arranged on the inner side of the concha cavity, a flexible clamping block 23 arranged on the outer side of the bulge of the concha cavity, a C-shaped elastic column 22 is arranged between the stimulator body 21 and the flexible clamping block 23, the data connection line 11 is connected to the outer surface of the flexible clamping block 23, and passes through the inside of the C-shaped elastic column 22 to be connected to the electrical signal of the stimulator body 21, and the electrode mechanism 3 is arranged on the stimulator body 21.

[0028] The above working principle and technical effect are: the control host 1 controls the stimulator body 21 through the data connection line 11, so that the electrode mechanism 3 connected to the stimulator body 21 performs electric pulse stimulation on the cymba concha through the discharge head 32 on the surface to achieve the treatment effect;

[0029] The elastic force of the C-shaped elastic column 22 generates a clamping force between the stimulator body 21 and the flexible clamp 23 connected thereto, which clamp the front and back sides of the ear respectively, so that the stimulator body 21 is fixed in the position of the concha cavity so that the discharge head 32 on the electrode mechanism 3 fits with the cymba concha.

[0030] In the previous embodiment: the electrode mechanism 3 includes an electrode column 31 adapted to the curvature of the cymba concha skin, and the discharge head 32 is fixedly arranged on the outer surface of the electrode column 31;

[0031] One end of the electrode column 31 is connected to a rubber column 33, and one end of the rubber column 33 is connected to a corner column 34;

[0032] A spherical hinge 35 is connected between the angle column 34 and the upper surface of the stimulator body 21 . A fastening bolt 351 for fastening the hinge ball is provided on one side of the spherical hinge 35 . The adjustment end of the fastening bolt 351 is arranged on the outer surface of the stimulator body 21 .

[0033] The above working principle and technical effect are as follows: the electrode column 31 is elastically supported by the rubber column 33. When the ear of different patients has different spatial shapes of the concha, the rubber column 33 elastically supports the electrode column 31, so that when the ear of different patients is treated, the rubber column 33 can be deformed adaptively, so that the discharge head 32 on the surface of the electrode column 31 is better fitted with the concha.

[0034] The setting of the spherical hinge 35 allows the angle column 34 to be universally adjusted on the upper surface of the stimulator body 21, so as to adjust the inclination angle of the electrode column 31, so that the discharge head 32 on the surface of the electrode column 31 can further and better fit with the cymba concha. The fastening bolt 351 is used to fix the position of the angle column 34 after the angle is adjusted, so that the electrode mechanism 3 is adapted to the patient currently using it.

[0035] Furthermore, a rubber column 33 is provided inside the rubber column 33, a wire hole B341 is provided inside the angle column 34, a through hole connected to the wire hole B341 is provided inside the hinge ball of the spherical hinge 35, the wire hole B341 is connected to the wire hole A331, and the wire of the control electrode column 31 passes through the wire hole A331 and the wire hole B341 to the inside of the stimulator body 21, so that the stimulator body 21 and the electrode column 31 are connected by electrical signals.

[0036] In the previous embodiment: a C-shaped frame 4 is also provided at the auricle position, the C-shaped frame 4 matches the curvature of the auricle edge, the lower end of the C-shaped frame 4 is fixedly connected to a connecting block 41, and the data connection line 11 is fixedly connected to the connecting block 41 and the flexible clamping block 23 from front to back, and the data connection line 11 between the connecting block 41 and the flexible clamping block 23 is provided with a length.

[0037] The above working principle and technical effect are: during vagus nerve stimulation treatment, due to the existence of the data connection line 11, it is easy to pull the data connection line 11 by mistake, causing the stimulator mechanism 2 to fall off, thereby causing the treatment to be interrupted;

[0038] The C-shaped frame 4 is hooked on the auricle, and the end of the data connection line 11 is first fixedly connected to the connecting block 41, so that when the data connection line 11 is pulled, the tension generated by the data connection line 11 acts on the connecting block 41, and is offset by the C-shaped frame 4, thereby avoiding the tension of the data connection line 11 directly occurring on the flexible clamping block 23, causing the stimulator mechanism 2 to fall off.

[0039] Furthermore, a side of the stimulator body 21 that fits the concha cavity is provided with a contact surface A211 that fits the surface of the concha cavity, thereby improving contact comfort.

[0040] Furthermore, a side of the flexible clamp 23 that fits the bulge of the concha cavity is provided with a contact surface B231 that fits the surface of the bulge of the concha cavity, thereby improving contact comfort.
