Nasal bone conduction hearing aid

Abstract

The disclosed nasal bone conduction hearing aid comprises: a tuning and control equipment to receive and treat external sound signal, a bone-skin conduction oscillation device with an oscillator to receive the signal from former equipment, and a carrier device on nasal part to bear said devices and make said oscillator close contact the nasal bone skin and convert the electric wave received by said oscillation device into oscillatory wave to send to nasal part and into inner ear.

Description

technical field [0001] The invention relates to a nasal bone conduction hearing aid device, in particular to a nasal bone conduction hearing aid device which transmits external sound to the inner ear through a nasal bone oscillator. Background technique [0002] According to the analysis of otolaryngologists, there are two types of hearing impairment: conductive hearing impairment and sensorineural hearing impairment. If you have problems with the above two types, it is called mixed hearing impairment. Patients with sensorineural hearing impairment are suitable for using air conduction hearing aids, but air conduction hearing aids are not suitable for patients with conductive hearing impairment. Only bone conduction hearing aids can help this type of patients; air conduction hearing aids must be placed in the external auditory canal and middle Bone conduction hearing aids are especially suitable for patients with atresia of the middle ear or external auditory canal or damage...

Problems solved by technology

[0005] However, the above-mentioned ear canal hearing aid must be kept clean because the hearing aid is inserted into the ear canal, and it needs to be cleaned frequently to avoid infection and inflammation of the ear canal. Hearing aids introduce sound into the ear through the air, often resulting in excessive noise

[0006] In another known bone conduction glasses-type hearing aid, the oscillator is placed at the end of the ear of the glasses frame to receive sound, but due to long-term use, the glasses tripod will become loose and cannot fit the ear bone, making the hearing aid The effect is greatly reduced; at the same time, the patient must use the glasses that have been designed. The heavy spectacle tripod is very inconvenient and unsightly, and sweating behind the ears will cause the hearing aid to lose its function; in addition, this type of bone conduction glasses Type hearing aids, if you want to use the left and right spectacle tripods, you cannot share components such as batteries, microphones, etc., which makes users have to pay nearly double the cost of purchase, which is not economical
