Common problems and solutions of household nebulizers

With the gradual improvement of nebulization therapy technology, the household popularity rate of medical nebulizers is gradually increasing. In the future, with the development of intelligent technologies (such as connecting to an APP to record atomization data) and personalized technologies (such as customizing atomization volume adjustments), household atomizers are expected to further integrate into the family health ecosystem and become a "standard configuration" for more families.

When using a medical nebulizer at home, you may encounter some operational or equipment issues. Timely and correct handling can ensure the treatment effect and safety. The following are common problems and solutions for your reference:

I. Issues related to equipment startup

The machine won't start up/doesn't work

Possible causes:

The power supply is not connected or the plug is loose (for compressor models);

Insufficient battery power (handheld network-type model);

Switch button failure or internal circuit problem.

Solution:

Check the power cord connection and replace the socket for testing;

Charge the handheld model or replace the battery (pay attention to the positive and negative poles);

If the button malfunctions, try gently pressing the reset button (if any), but it still doesn't work. Contact after-sales service for repair.

2. There are no atomized particles or no mist is produced after startup

Possible causes:

The medicine cup was not installed correctly or the sealing ring fell off, resulting in air leakage.

Failure of the air compressor in the compression type model (such as the fan not rotating);

The vibrating plates of the grid-type model are clogged or damaged.

Solution:

Remove the medicine cup, reinstall it and tighten it. Check if the sealing ring is misaligned.

Listen to the sound of the compressor. If there is no movement at all, it may be that the fuse has blown or the motor is damaged, and professional repair is required.

For the mesh model, a few drops of clean water can be added for testing. If there is still no fog, gently wipe the vibration plate with a cotton swab (do not use hard objects to scrape). If it is severely clogged, the atomization plate needs to be replaced.

Ii. Issues related to atomization effect

1. The fog volume is too small or the atomization speed is slow

Possible causes:

The air inlet filter screen of the compression type model is clogged (such as dust, hair);

The amount of liquid medicine is insufficient (below the minimum scale line);

The liquid medicine of the mesh model is too viscous (if not diluted).

Solution:

Remove the air inlet filter screen of the compressor (usually on the side or bottom of the machine), clean it with soapy water, dry it and then reinstall it.

Add the liquid medicine to the recommended mark (generally 2-4ml), and avoid exceeding the maximum volume.

Dilute the liquid medicine as prescribed by the doctor (such as a mixture of normal saline) to ensure good fluidity.

2. The fog particles are large or highly irritating

Possible causes:

The wrong type of equipment was selected (such as using a netted model to treat lower respiratory tract diseases);

The temperature of the liquid medicine is too low (use refrigerated liquid medicine directly);

The atomization mask is too far from the face, causing particles to settle in the air.

Solution:

For lower respiratory tract diseases (such as pneumonia and asthma), compression nebulizers (with a particle size of 1-5μm) are preferred. For upper respiratory tract problems (such as rhinitis), mesh nebulizers can be used.

Take out the liquid medicine half an hour in advance and warm it up to close to body temperature (do not exceed 40℃ to avoid the medicine losing its efficacy).

The mask fits closely to the face, reducing gaps to ensure that the mist particles are inhaled directly.
