Description

Tinnitus multiband optical treatment equipment and use method thereof

Technical Field

Background

Tinnitus is a very common disease that can have some degree of adverse effects on the mood, work and life of the patient. Tinnitus may be caused by dysfunction of either the peripheral auditory system or the central nervous system. Cochlear and intracochlear neuropathy are a large inducing factor of tinnitus. The cochlea includes inner and outer hair cells (IHC and OHC), wherein the IHC mainly receives sound information, the OHC plays a role in auxiliary regulation, and the uncoordinated damage of the Outer (OHC) and Inner (IHC) hair cell systems can cause tinnitus. Tinnitus can be caused by either intra-cochlear ion imbalance or by dysfunction of the cochlear neurotransmitter system.

The internal ear artery of human is the terminal branch of artery, which exists singly without collateral circulation, so that the internal ear is easy to generate microcirculation disturbance, which affects the blood supply of the internal ear, and the auditory hair cells generate oxygen deficiency, and generate the pathological changes of ear nerves such as hearing damage, tinnitus and the like.

The hemorheology can be improved by irradiating the inner ear blood vessel, so that the specific volume of erythrocytes, fibrinogen and platelet aggregation are reduced, the fibrinolytic activity is enhanced, and the blood viscosity is reduced. And the heat effect generated by illumination can improve the blood flow rate and improve the microcirculation of the inner ear, and has positive effect on treating tinnitus. The students use low-power laser to treat patients, and the low-power laser has a positive effect on improving tinnitus.

However, the laser treatment tinnitus device is limited by the volumes of the laser and the laser power supply, is often heavy, the tinnitus treatment process is long, and the heavy laser treatment device is only suitable for being used in hospitals and is not suitable for home treatment of patients. In addition, because the price of laser instrument is higher, improved tinnitus phototherapy device's cost, be unfavorable for the popularization of equipment. The output wavelength of the laser therapeutic apparatus is single, and the therapeutic effect is limited; moreover, in order to ensure the safety of the patient, the light power is limited to a very low range, which is not beneficial to the treatment of tinnitus.
