Description

Technical Field

[0001] The utility model relates to the technical field of cochlear implants, in particular to a cochlear implant protective cover. Background Art

[0002] A cochlear implant is an implantable hearing aid device used to restore hearing to people with severe or above sensorineural hearing loss. It has been widely used in clinical practice. The cochlear implant picks up sound signals through an external microphone, processes and encodes the sound signals in a processor, and then emits electrical pulses through electrodes implanted in the cochlea to stimulate the remaining auditory nerves, thereby replacing the sound-to-electric conversion function of the hair cells and reconnecting the external sound environment with the auditory nerve pathway. Different from the hearing compensation method of hearing aids that uses residual hearing "acoustic hearing" to amplify sound, the cochlear implant uses electrical pulses to directly stimulate the auditory nerve to produce "electrical hearing", which essentially changes the perception of sound from nothing to something. It is mainly suitable for people with severe or above hearing loss.

[0003] When a user uses a cochlear implant, the external device of the cochlear implant is placed close to the side of the head and needs to be used in various climate environments and physiological conditions. Rain or sweat will have an adverse effect on the operation of the external device of the cochlear implant and will also corrode the wire connections.

[0004] The utility model patent with publication number CN208660142U discloses an external cochlear implant device, including a first protective cover arranged outside the language processor and a second protective cover arranged outside the coil, which can effectively prevent sweat from entering and corroding, thereby extending the service life. At the same time, the connecting end of the coil and the wire is placed in the same cavity. Even if the coil and the wire are separated and not affected by external force, the wire will not fall out of the cavity, thereby avoiding accidental loss of the device. However, the external cochlear implant device still has the following problems when in use: (1) The coil protection section, wire protection section and transition section in the second protective cover are designed as an integrated unit. Since the wire protection section and transition section are all enclosed around, when connecting the wire to the coil, the end of the wire needs to be blindly inserted into the wire protection section and transition section, which is not convenient for connecting the wire; (2) Due to the setting of the second protective cover, the coil is easily loosened when it is magnetically attracted to the user's head. In addition, the language processor may fall off when worn on the user's ear. Especially for some young children, the coil and language processor may be lost as a whole during exercise. Utility Model Content

[0005] In view of the above-mentioned problems, the present utility model aims to provide a cochlear implant protective cover. By providing a wire cover, connecting a hanging rope to the wire cover, connecting a fixing piece to the end of the hanging rope, and fixing the fixing piece to the user's clothes, the entire cochlear implant external device can be prevented from being lost. In addition, the upper sides of the wire segments on the first protective cover and the second protective cover are open structures, which facilitates the connection of the wires to the coil and the language processor.
