Is there a lifespan for hearing aids?

Frequently, some customers will ask questions about how long the hearing aid lasts.Today Huizhou Jinghao Medical will share this topic.A deaf friend may use a hearing aid, so is there a life limit for the hearing aid?

Hearing aids, like other electronic appliances, have a lifespan for hearing aids.Although the hearing aid brands are different in different styles (box hearing aids, behind-the-ear hearing aids, in-ear hearing aids, glasses-type hearing aids, bone-guided hearing aids), the hearing aids are generally used for 5-8 years, and often during the fitting. Commissioning under the guidance of the division.If the hearing aid is used properly and maintained in a timely manner, its life can be significantly extended.

Since we know the working principle of hearing aids, how can we maintain the hearing aids in the normal life process so that the hearing aids can serve us for a longer time?Maintaining hearing aids is also an important task.

Pay attention to the following points when servicing hearing aids:

First, it is moisture-proof, shock-proof and high-temperature resistant.The hearing aid should be placed in a cool, dry place, and you should not take a hearing aid to take a bath or swim.In the evening, put the hearing aid in a desiccant box, avoiding light, avoiding high temperature and high humidity environment, and avoiding falling.Do not repair it yourself.

The second is to clean the hearing aid at least twice a week.

The third is to regularly check the battery voltage and replace it in time.If it is not used for a long time, remove the battery and place it in a cool, ventilated place.

The fourth is that the volume potentiometer rotates smoothly.

Five to prevent sweat from entering the ear, when sweating, dry it.

Sixth, we must correctly use the function and volume control switch, and try to lightly turn off the light to avoid excessive force and excessive force.Finally, the hearing aids are sent to the Matching Center for regular maintenance every six months or a year. The hearing aids are cleaned by professionals to ensure that the hearing aids are in good condition.

Different types of hearing aids, the maintenance measures taken sometimes will be different, let us look at the maintenance of the box, behind the ear and in-ear hearing aids:

 For the box machine, pay attention to using a good quality alkaline battery and replace the battery without electricity.Remove the battery when not in use for a long time to avoid leakage of the battery and corrosion of the hearing aid circuit.When the volume potentiometer and switch are turned, the force is too strong to avoid potentiometer damage and switch damage.

For the back and back machine, harmful tiny objects such as sweat and dust can easily enter the inside of the hearing aid from the tiny gaps of the potentiometer, switch and battery compartment.Especially in the summer, because the human body is prone to sweat, it must contain salt, alkali and other ingredients in sweat.And easy to enter the hearing aid to produce a chemical reaction.Thereby causing corrosion damage to the microphone, receiver, movement and other components of the hearing aid.Therefore, in the summer, be careful to wipe the sweat with a dry towel or paper towel to prevent sweat from flowing into the hearing aid.When bathing, remove the hearing aid and place it in a dry, reliable place.For ear molds, always clean the sputum or foreign objects on the ear mold.If there is ear oil or earwax in the sound tube, or if the temperature difference changes greatly, the sound tube will easily form a water vapor blocking sound tube. In this case, the sound tube of the hearing aid can be removed from the sound tube. The ear hook is unplugged, and the foreign matter in the sound tube is blown off with the earball, but it cannot be blown dry with a hair dryer, because the hotter wind will bend and deform the sound tube.After cleaning, install the sound tube.

For in-the-ear hearing aids, since the plug forms a relatively closed space in the ear canal, it is necessary to pay attention to moisture and ear wax.The sound port of the in-ear hearing aid is in the ear canal. The secretions and fistulas in the ear canal easily enter the receiver through the receiver tube or vent. When these substances enter the receiver, they accumulate inside the receiver and damage the hearing aid.Causes the sound to become light, distorted, or directly cause the hearing aid to be silent, causing the receiver to be completely damaged.Therefore, wear an in-ear hearing aid, pay attention to clean the ear canal with a clean cotton swab before wearing the hearing aid, keep it hygienic, and then put the hearing aid on.After using the hearing aid, clean foreign objects around the baffle and on the hearing aid.When the hearing aid is not in use, open the battery compartment and store it in a dry bottle containing an effective desiccant.
