Atomization inhalation therapy is an important and effective treatment for respiratory diseases. The aim is to export the inhaled drugs in the form of aerosols and enter the body with breathing. Drug particles with a diameter of 1-5um are most suitable. Compared with the traditional injection and medication treatment, atomization treatment has a faster effect and lower dosage of redundant routes, which is 1/10 of oral dose. The treatment is simple, humidifying airway and diluting sputum.
