An electroacoustic stimulator for treating tinnitus

technical field

The utility model relates to an electroacoustic stimulator for treating tinnitus, which belongs to the field of electronic medical instruments.

Background technique

Tinnitus is an urgent problem in otology. Currently, there is no effective drug or method approved by the U.S. Food and Drug Administration (FDA). In recent years, studies have shown that vagus nerve stimulation combined with sound therapy has a certain effect on relieving tinnitus symptoms, but the specific mechanism is still unclear. It is well known that when the vagus nerve is stimulated, it increases the secretion of norepinephrine from the amygdala, prompting the amygdala to strengthen the emotional memory at that specific time. Vagus nerve stimulation combined with sound stimulation therapy uses this feature to treat tinnitus. At present, the mechanism recognized by scholars at home and abroad is to stimulate the vagus nerve of tinnitus patients while giving acoustic signals (the frequency of noise generated by tinnitus is about 16khz, so the acoustic signals we give to patients are 0~20khz except for the frequency of 16khz. Pure tones in the frequency range), so that the patient's auditory cortex enhances the perception of the received acoustic signal, so that by repeatedly giving the patient vagus nerve stimulation with acoustic signal stimulation, the neurons of the auditory cortex of the tinnitus patient will reshape, that is, their ability to perceive other frequencies Neurons (beyond 16khz) will expand and neurons that perceive tinnitus will decrease, causing the brain to "ignore" the tinnitus. In 2011, the Engineer team stimulated the vagus nerve by burying a spiral electrode on the vagus nerve trunk in the left neck of the rat, and at the same time gave different acoustic signals to stimulate the rat, successfully inhibiting the abnormal activity of the cerebral cortex of the rat with tinnitus, and making the auditory cortex Neuronal activity returns to normal levels. At present, there are also cases in foreign countries where electrodes are buried on the left vagus nerve trunk of patients, and specific sound stimulation is given at the same time to treat tinnitus. However, the above-mentioned treatment methods are not only traumatic for patients, but also very expensive, which is difficult for ordinary patients to accept and difficult for clinical promotion. On the other hand, the clinical anatomical relationship shows that the distribution of vagus nerve fiber endings in the concha is very wide, reaching 45% in the concha cavity and 100% in the concha cavity, making percutaneous vagus nerve stimulation combined with sound masking to treat tinnitus possible.

Traditional Chinese medicine believes that the ears are closely related to the functions of the meridians and viscera. "Lingshu? Evil Qi Viscera Disease Form" says: "Twelve meridians, three hundred and sixty-five collaterals, the qi and blood are all on the face and go through the orifices. , its essence and yang qi go up to the eyes to become the eyes, and its other qi goes to the ears to be heard." "Health Treasure Book" pointed out that "the internal organs and six internal organs, and the twelve meridians all have collaterals in the ears." Clinical experience shows that ear It is most closely connected with the Sanjiao Meridian of Hand Shaoyang and the Gallbladder Meridian of Foot Shaoyang. Auricular acupuncture or auricular pressure therapy is a branch of acupuncture. Many clinical observations have shown that stimulation of acupoints around the ears can improve tinnitus, such as acupuncture at Tinggong acupoint, or inner ear, kidney, outer ear, subcortex, and Shenmen. Auricular points such as , adrenal gland, and heart have a positive effect on nervous tinnitus, and the mechanism may be related to the fact that Chinese medicine can benefit the kidney and unblock yang, soothe the liver and gallbladder, and regulate the flow of qi.

The treatment of tinnitus by acupuncture point stimulation in traditional Chinese medicine undoubtedly coincides with the above-mentioned plastic changes in the central nervous system induced by vagus nerve surgery. However, the traditional auricular acupuncture instruments currently on the market only have simple auricular acupuncture electrical stimulation or simple sound maskers, and there is no sound-electric compound stimulator. Therefore, we propose a combination therapy of electroacupuncture at auricular points plus sound stimulation for tinnitus, that is, a pure tone playback device is added to the traditional ear acupuncture instrument to meet the needs of patients.
