Description

Technical Field

[0001] The invention belongs to the technical field of electrical stimulation therapy, and in particular is an in-ear electrical stimulation device for treating tinnitus. Background Art

[0002] The cochlear implant has a high-strength titanium shell and a number of electrodes. The electrodes are soft electrodes to reduce trauma to the internal structure of the cochlea. The length of the electrode array is moderate, covering the spiral ganglion cells in the cochlea, ensuring the hearing effect while avoiding the damage caused by deep insertion and the challenge of surgery. Studies have found that cochlear implants may cause potential damage to any remaining structures of the cochlea and may be involved in the apoptosis mechanism that leads to cell death. Electrode insertion may affect tinnitus. In addition, the suppression of tinnitus after cochlear implantation is immediate, indicating that the remodeling of the central mechanism of tinnitus still relies on the existence of peripheral afferents. Currently, cochlear implants are mainly used to treat deaf patients, and there is no single device for treating tinnitus. Currently, cochlear implants are fully implanted, the surgery is complicated, and the price is expensive. In addition, the above studies have found that although cochlear implants can improve tinnitus in most people, there are also cases of aggravation or ineffectiveness.

[0003] For example, a Chinese patent document discloses an in-ear electrical stimulation device for treating tinnitus (Announcement No.: CN213432587U). Although this patent has an electrical stimulation circuit inside the host and is provided with an in-ear earplug, the corresponding part of the in-ear earplug is provided with an electrical stimulation contact point, and the electrical stimulation contact point needs to fit on the surface of the human ear canal. At the same time, the electrical stimulation circuit controls the corresponding voltage of the electrical stimulation contact point, and the voltage is provided according to the patient's age / patient's condition. Because the electrical stimulation contact point fits the human ear canal, the electrical stimulation voltage transmits the stimulation signal to the human auditory nerve through the ear canal, and improves the nutrition of the human auditory nerve through electrical stimulation, thereby improving the patient's tinnitus.

[0004] However, the ear hook is relatively fixed in design, so the position of the in-ear earplug cannot be adjusted. Since people's ears are different in size and shape, the use of fixed and non-adjustable ear hooks will restrict wearing, which will not only cause looseness but also reduce wearing comfort. In addition, the ear hook is hung on the inner side of the ear helix in a single arc shape, and has poor stability, which can easily cause the ear hook to fall off during exercise, thereby causing damage.
