4. Atomizing particles: Small (less than 2.5μm) atomized particles can reach the lower respiratory tract and alveoli. Generally, the specification parameters provided by manufacturers are labeled with the size of atomized particles. The labeling of atomized particles generally involves drug particle size, mean drug particle size (MMAD), mean median size (MMD), etc. The size of atomized particles is affected by two factors: compressor and atomizing cup. The compressor provides air with constant pressure, and the process of atomizing cup determines the level of particle size.
Such as: "Nan Nuo Wuerkang" brand compression atomizer, atomizing particles (drug size) 80% 0.5 ~ 5μm
The average median diameter (MMD) of "Bairui" compression nebulizer is 3.5μm, and the percentage of particles less than 5μm is 68%
The average median diameter (MMD) of "Wuchang" compression nebulizer is 3.5μm, and the percentage of particles less than 5μm is 76%
5, portability: the smaller the volume, the better
When it comes to home use, the size of the atomizer is also a consideration for home users. A smaller size means more portability, which requires more attention if you need to travel during atomization treatment
6. Design and appearance quality
