Mesh nebulizer is a new type respiratory diseases curing machine. It transforms the liquid drug into mist and with inhalation, the drug directly enters into respiratory tracts and lungs, achieving an painless, fast and effective aerosol therapy. It was driven by the circuit rapid oscillation, Piezoelectric ceramic transducer starts resonant oscillation and generates the rapid oscillation of the mesh, through which, the liquid drugs are popped out rapidly while generating numerous small mist particles.(1-5μm)
