[0002] Auricular vagus nerve stimulation is a modernized form of traditional Chinese medicine auricular acupuncture and a key component of modern acupuncture. Clinically proven, this electrical nerve stimulation therapy, which combines electronic technology with traditional acupuncture meridian theory, is effective for treating neurological disorders. The vagus nerve controls most organs of the respiratory and digestive systems, as well as the heart's sensory and motor functions and glandular secretions. Electrical stimulation of the vagus nerve has been shown to be a valuable adjunct treatment for epilepsy, diabetes, insomnia, depression, and other conditions.

[0003] Based on the above, the inventors have discovered the following problems: current ear vagus nerve stimulators mostly consist of two parts: a stimulator body and an ear electrode device. The stimulator body and the ear electrode device are connected by a connecting wire. Long connecting wires can cause the wires to become messy or entangled, thereby affecting the treatment of the patient group.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an electrode device for an ear vagus nerve stimulator is provided, in order to achieve the purpose of having greater practical value. Utility Model Content
