Hearing aid maintenance, moisture is the key. Tell the patient to remember that hearing aids can not enter the water, wash your face, bathe, swim and rain must be removed from the hearing aid. The moisture-proofing method is the same for any hearing aid. Remove the hearing aid every night before going to bed and place it in a container with desiccant (if it is used every day, the battery compartment can be opened at this time without removing the batteries). When the color of the desiccant changes, treat it accordingly and renew it if necessary. The hearing aid should not come into direct contact with the desiccant to prevent corrosion by the damp desiccant.
2, cleaning
Appropriate cleaning can improve the service life and effect of hearing aids. Because hearing aids need to be worn frequently, the human body produces excretions (such as earwax, ear secretions, etc.) will affect the service life of the hearing aid to varying degrees, so every user wearing a hearing aid must often clean the hearing aid. The specific cleaning methods for hearing aids are as follows:
After each day's use, use a dry, soft cloth to clean the earwax and sweat from the surface of the hearing aid. For customized machines, you should check whether the sound tube is blocked by earwax and whether the microphone entrance is blocked by dust. If this condition is found, a special small brush should be used to clean it. For behind-the-ear hearing aids, if the acoustic tube of the earmold is found to be blocked by earwax, it should be cleaned in time. If there is a small droplet of water in the acoustic tube of the earmold, you can always suck out the small droplet of water or shake it dry. For cassette hearing aids, the earplugs should be cleaned of earwax.
3, battery preservation and replacement
Buying hearing aid batteries, need to pay attention to the battery type, and should not be purchased at a time too much, and need to be stored in a cool, dry place.
When users do not use their hearing aids, they should open the battery compartment door and remove the batteries. When the battery power is lower than a certain level, the hearing aid will stop working, or emit a "beep" sound, or the sound quality becomes rough and unstable, at this time, the battery should be replaced immediately, and pay attention to the battery polarity when replacing. If you don't use it for a long time, you should take the battery out and put it in another place to prevent the battery from leaking and corroding the hearing aid.
