2. Working Principle
The working principle of atomizer is driven by the rapid oscillation of the circuit, the piezoelectric
ceramic in able to harmonic oscillation, thus promote rapid oscillation microporous metal mesh,
make solution through tiny mesh and metal mesh was rejected by the rapid, forming numerous
tiny atomized particles, the attachment (suction mask or mouthpiece) lead to patients with
respiratory system, to achieve the goal of inhalation therapy.
The respiratory system is an open system. After the drug liquid is atomized into particles, the
patient inhales the drug mist, which can be directly adsorbed and deposited in the patient's
mouth, throat, trachea, bronchus, alveoli, etc., and absorbed by the mucous membrane and
other tissues to achieve the purpose of treatment.
3. Intended Use
The device is a mesh nebulizer designed to aerosolize liquid medication for inhalation therapy in
professional healthcare environment and in home healthcare environment.
Suitable for pediatric and adult patient, infants, children and compromised individuals should be
used under adult supervision.
4. Contraindications
1) This product does not apply pentamidine drugs.

supply.
1) Remove the components from the main unit: the medicine cup components (including
medication cup, lid), connector, mask, etc. And soak all the components in clean water (which is
no more than 40 degrees centigrade) for about 5 minutes.
2) After cleaning, wipe all the components with clean and sterile medical gauze, and keep them
dry sufficiently.
3) Wipe the outer shell of main unit. If there is residue medicine remaining at the electrode
contact, please clean it with wet sterile medical gauze. After cleaning, keep the main unit dry.
4) Store the all parts in a dry and clean place to avoid contamination.

The main unit can not be washed with water to prevent water from entering the main unit.
Use clean sterile gauze to wipe off water on the main unit and components. Keep them dry to
ensure safe use next time.

15
Warning:
The masks must not be placed in hot water!
2. Disinfection
After each use, it is necessary to disinfect the components, including medication cup, lid,
connector, mask, etc. The disinfection methods are as follows:
1) Disinfection with hydrogen peroxide
Disinfect all the components by placing them in 2% hydrogen peroxide for 10 minutes, including
medication cup, lid, connector, mask. After disinfection, rinse all the parts with distilled water,
then wipe with clean and sterile gauze.
Do not use strong oxidizing agents such as perchlorate or disinfectants that are corrosive to
metals, polymer compounds.
Note:
1) Disinfectants remaining on components need to be wiped with sterile medical gauze to
ensure safe use next time. Do not touch the central area of the mesh diaphragm when washing
or cleaning the spray connector, so as to avoid damaging the mesh diaphragm.
2) The spray assembly is composed of a medication cup and a connector. When cleaning and
disinfection, you should loosen the connector by using a screwdriver.
3. Drying
Dry the parts carefully using a soft cloth. Shake the spray assembly gently(5~10 times), so that
the water inside the mesh is removed from the tiny holes.
Place the parts on a clean, dry and absorbent surface and leave them to dry completely (at
least 4 hours).
Note:
Please ensure that the parts are completely dry after cleaning, otherwise the risk of bacterial
growth is increased. Place the parts in a dry, sealed container. Ensure that the spray assembly
is completely dried off by shaking. Otherwise, the nebulization may not work after reassembling
the device.
