Embodiment

[0020] figure 1 It is a schematic cross-sectional view of the structure of the human ear, which consists of the outer ear, middle ear and inner ear. The outer ear consists of the pinna 2 and the ear canal 1 . The middle ear is composed of the tympanic membrane 7 , the malleus 3 , the incus 4 and the stapes 5 . The inner ear is mainly composed of the cochlea 6 . For the normal human ear, the sound passes through the ear canal 1 and causes the tympanic membrane 7 to vibrate, driving the ossicular chain (malleus 3, incus 4 and stapes 5) to vibrate, and the mechanical vibration is transmitted to the inner ear, and the vibration of the basilar membrane in the inner ear stimulates the hair cells Nerve impulses are produced to make people hear. Deaf patients can be divided into two categories according to pathology: conductive deafness and sensorineural deafness. Conductive deafness refers to the obstacle of the sound transmission path, and the treatment method is artificial ossi...

Abstract

The invention provides an implant-type hearing-aid device wirelessly powered and capable of prompting electric quantity. The implant-type hearing-aid device comprises a wireless power supply system, an electric quantity prompting system and an implant-type hearing-aid device, wherein the implant-type hearing-aid device is provided with a piezoelectric vibrator designed on the basis of the piezoelectric effect selection piezoelectric stacking way, the piezoelectric vibrator is arranged in an implanting body, the implanting body is fixed on the wall of a human drum by virtue of a fixed support, and the other end is connected with incus; and the implant-type hearing-aid device comprises a wireless power supply system receiving device and an electric quantity detection module. The electric quantity detection module can detect the electric quantity of a chargeable battery in the implanting body, when the electric quantity of the battery is lower than a set value, the feedback information is transmitted by virtue of a wireless communication module, and after an external receiving terminal receives the signal, a patient can be reminded for charging the battery in time. In addition, the hearing-aid device is not subjected to the electromagnetic interference, the high-frequency gain is high, and the effect for improving the hearing of the patient with medium to severe sensorineural hearing loss is obvious. The implant-type hearing-aid device is reasonable in design, simple in structure and suitable for optimizing the hearing-aid device.

Description

technical field [0001] The invention relates to an artificial middle ear hearing aid device for curing the hearing loss of deaf patients. The hearing aid device adopts wireless energy supply technology, and an external receiving device can display the power to remind the patient to charge in time. Specifically, the device is fully implanted into the human ear, and hearing compensation is achieved through mechanical excitation; the device uses wireless power supply, and the power status of the device can be displayed on the external receiving device through the transmitting device, reminding the patient to charge in time. Background technique [0002] Hearing loss has become a common disease nowadays. Especially with the aging of society, more and more people suffer from sensorineural deafness due to the aging of the auditory system, and then affected by modern industry, living noise and occupational environment make more people's hair cells affected The number of patients w...
