Description

[0001] The present invention relates to a tinnitus treatment device using electric stimulation,

The present invention relates to an apparatus for treating a tinnitus using an electric stimulation method.

It is called the auditory organ collectively called the peripheral sensory organs that accepts sounds and converts them into auditory signals and transmits them to the brain. The auditory organ is divided into the outer ear, the middle ear, and the inner ear. The sound from the outside through the outer ear vibrates in the eardrum and then passes through the middle ear to the inner cochlea (cochlea).

Auditory hair cells (hereinafter referred to as 'auditory cells') are arranged on the basal membrane of the cochlea, and the total number of auditory cells arranged on the basal membrane is approximately 12,000. The basement membrane is about 2.5 to 3 cm in length. The auditory cells located at the basal membrane perceive a high frequency and the auditory cells located at the basal membrane perceive a low frequency.

This is known as the frequency specificity of auditory cells, and the frequency specificity resolution at the ideal stimulus intensity level is known to range from about 0.2 mm (0.5semitone) on the basement membrane.

Tinnitus is a type of hearing-related illness that refers to symptoms that are distressed by the perception of continuous noise even when there is no external sound source.

It is reported that about 15% of the total population in Korea experiences tinnitus, about 8% of the severity of sleep disorder, and about 1% of severe disability in daily life.

Especially, with the development of the industry, the number of the patients is increasing due to the increase of the noise, the increasingly complicated mental diseases, the increase of the elderly population, and the abuse of drugs.

The causes of tinnitus vary widely depending on the cause of the diagnosis. Drug therapy for injecting neurotransmitter blockers, surgery for correctable brain tumors, vascular diseases, muscular diseases, and noise generators like hearing aids There is a tinnitus-masking method that makes the sound of a patient's tinnitus sound larger than that of the tinnitus from the outside, so that the tinnitus can not be heard.

And tinnitus retraining therapy, which is a combination of sound therapy and counseling that continually speaks a little less than real tinnitus over a wide frequency range.

However, the sound-based treatment, which simply transmits the sound through a conventional hearing aid or a noise generator, has recently been analyzed by collecting systematic research results. As a result, the effect of the sole tinnitus therapy is uncertain, There was a low problem.

In addition, transcranial magnetic stimulation, which applies electrical stimulation to the cerebral cortex through the skull during the conventional tinnitus treatment, is costly because it can only be treated using expensive equipment in large hospitals .

In addition, conventional tinnitus therapy with electrical stimulation has been used for cochlear implantation and cochlear implantation. However, it has been reported that the tinnitus has disappeared after cochlear implantation, Is also reported in many cases.

Particularly, the cochlear implantation method requires the insertion of the electrode into the cochlea, so that there is a high risk of residual hearing loss of the MR. In the cochlear implant method, the probe electrode is inserted through the eardrum and positioned near the cochlea, Tinnitus can be relieved by continuous use and it is difficult to stimulate the exact location, so the treatment effect was limited.
