Child hearing aid maintenance tips–How to maintain children’s hearing aids
1. Earwax damage
Blockage of ear wax is the main cause of damage to expensive receivers. Chinese earwax is generally dry. Normally during normal speech, chewing, walking, most of the earwax will gradually vibrate out of the ear canal due to vibration, but some will remain in the ear canal, especially when wearing custom. After the machine, the ear canal is blocked, the earwax can not fall out normally, the earwax can’t go to the receiver hole of the machine, but the sound is lightened, and the child hearing aid severely blocks the receiver and causes damage. Bring unnecessary losses.
Regular cleaning of the receiver hole requires the dealer and the user to work together. Do not underestimate the small earwax, which may bring you huge losses and inconvenience. According to the instructions of the manual, the earwax is cleaned, which takes a lot of time but can save you a lot of maintenance costs and avoid the use of inorganic yarns.?
2. Water vapor hazard
One of the biggest enemies of hearing aids is water vapor. It is generally known that water vapor will enter and accumulate inside the hearing aid from the gap between the battery compartment door and various adjustment knobs, affecting the internal wiring of the hearing aid, causing the volume of the internal cavity of the custom machine casing to store moisture, corrosive movement and internal wiring. Therefore, in normal use, be careful not to let the water vapor in the surrounding environment enter the hearing aid, such as adjusting the hearing aid with wet hands or showering the rain.
It is not known that water vapor can enter the receiver cavity from the receiver hole of the custom machine. In the southern part of China, the high temperature period is very long throughout the year, so it is often washed and showered every time. The homework that must be done, usually after a shower in the shower, it is inevitable that a small amount of water will splash into the ear canal. A normal person’s ear canal will have a little water to evaporate quickly, but if the deaf person wears a custom machine without drying in the ear canal, it will completely block the water between the custom machine and the eardrum. In the channel space, the water becomes water vapor after being heated, enters the cavity of the receiver, and then gradually cools and accumulates into liquid water. The extremely small parts in the receiver are continuously immersed, and the receiver is damaged, and the sound is abnormal. Reimbursement of the receiver.
It can be seen that it is very important to note that the child’s hearing aid keeps the ear canal dry. When the hearing aid is not in use, it should be placed in the desiccant to suck the water vapor from the machine, which will bring a very long service life to your hearing aid.
3. Shock damage
Hearing aids are very afraid of falling like quartz watches, because the components in the hearing aids are connected by very small wires, which are very easy to break after being impacted. Especially the receiver is due to its structural relationship, the internal sounding vibrating reeds and thimbles are very Easy to displace and deform after impact, causing distortion or silence(See the detailed introduction to the structure of the receiver).
In the production process of the receiver, if the receiver falls from a height before the packaging, the only way to deal with it is to scrap, and the receiver is not resistant to shock.
After the receiver is installed in the hearing aid casing, although the impact resistance is improved, it is still highly important to prevent the impact from falling. Due to its small size, the custom machine is easier to slip off the hands when wearing or removing, so be sure to pay attention to this.
Hearing aid preservation
Child hearing aidWhen not in use, turn the switch off and open the battery door to extend battery life. If the hearing aid is not turned off, it will emit“吱吱“The whistling sound may cause the attention of children or pets, resulting in unnecessary damage.
Therefore, store the hearing aid in a place where children or pets are not easily found. If the hearing aid is not used for a long time, store it in a special pocket and store it in a cool, dry place.
Cleaning and maintenance
To develop the habit of cleaning the hearing aid every day, use the company’s brush to remove the earwax or other tiny particles that accumulate around the ear canal of the hearing aid, the volume adjustment knob and the battery compartment, and then gently wipe the hearing aid with a soft cloth. Never use solvents, cleaning fluids or oils to clean your hearing aids.
Because the hearing aids are very delicate, it is best to carry them on the tablecloth with a soft cloth or towel during cleaning and maintenance to avoid unnecessary damage or missing parts.
Once you have adapted your hearing aid, sometimes you will forget that it is working, so be sure to take out the hearing aid when you are swimming, bathing or using a hair spray. Of course, when washing clothes, check if there are hearing aids in your pocket.
