Technical Field
[0001] The utility model belongs to the technical field of medical health care, in particular to an ear vagus nerve stimulator. Background Art
[0002] An auris vagus nerve stimulator is a wearable device that stimulates the vagus nerve. The vagus nerve is the longest and most widespread mixed cranial nerve in the body. The auricular branch of the vagus nerve is the only superficial branch of the vagus nerve, distributed in the cavum conchae and cymbiformis on the outer surface of the auricle. By electrically stimulating the auricular branch of the vagus nerve, the device projects to the nucleus tractus solitarius and transmits electrical signals to areas of the brain associated with epileptic seizures, thereby reducing or controlling abnormal neuronal discharges in the brain and controlling epileptic seizures. It can also improve symptoms such as anxiety, depression, sleep disorders, migraines, and cognitive impairment by regulating neurotransmitter expression and increasing local brain blood flow. An auris vagus nerve stimulator typically consists of two parts. One part is worn on the ear, the wearable part. The auricular electrodes on the wearable part stimulate the auricle, while the earbud electrodes stimulate the ear canal opening. The device stimulates the user's auricular vagus nerve by emitting electrical pulses. The other part is held by the user, the main unit, to adjust the device's operating mode. The two parts of the auricular vagus nerve stimulator are connected by a wire to enable data transmission between them.
[0003] Currently, the wearing part is worn on the user's ear. Since there is no fixed structure connecting the wearing part and the ear, the ear structure and size of different users are different, and the wearing part cannot better fit the user's ear, affecting the stimulation of the auricle electrode and the earplug electrode on the earmi acupoint. Utility Model Content
[0004] The purpose of the utility model is to provide an ear vagus nerve stimulator, which can better adjust the fit between the wearing part and the user's ear, and ensure the therapeutic effect of electrical stimulation of the ear vagus nerve acupoint.
[0005] The ear vagus nerve stimulator includes a stimulator main unit and a wearing part. The stimulator main unit is connected to the wearing part via a wire. A first fixing rod is vertically provided on the side wall of the wearing part. An ear hook with a "C"-shaped structure is provided on the top of the first fixing rod. An elastic rod with an "Ω"-shaped structure is fixed to the movable end of the ear hook. A connecting rod is fixed to the movable end of the elastic rod. A second fixing rod is provided at the bottom of the first fixing rod. A fixing block is fixed to the movable end of the second fixing rod. A through hole is provided on the fixing block for the connecting rod to pass through.
[0006] Furthermore, a first threaded hole is formed on the top of the first fixing rod, and a first threaded rod fixed on the ear hook is threadedly connected to the first threaded hole.
[0007] Furthermore, a second threaded hole is formed at the bottom of the first fixing rod, and a second threaded rod fixed on the second fixing rod is threadedly connected in the second threaded hole.
[0008] Furthermore, a magnet in a ring structure is provided on the inner wall of the through hole.
[0009] Furthermore, the connecting rod is made of metal material.
[0010] Furthermore, the ear hook is independently provided with a protective cover.
[0011] Furthermore, the protective cover is made of silicone material.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The utility model connects the stimulator host to the wearing part through a wire, and then the wearing part is worn on the user's ear. The ear hook on the wearing part is hung on the helix of the user's ear. According to the size of the user's ear, the elastic rod is adjusted to make it rest against the back side of the user's ear, and then the connecting rod is inserted into the through hole on the fixed block, so that the wearing part can better fit the ear to prevent it from falling. The fit between the wearing part and the user's ear can be better adjusted to ensure the therapeutic effect of electrical stimulation of the ear acupoints. BRIEF DESCRIPTION OF THE DRAWINGS
