When purchasing a compressed atomizer, pay attention to the following points:
1. Compressor
1. Noise: The noise of the atomizer is an important indicator of its quality
The loud noise will affect the mood of the patients who are already bad.
The noise of compressed atomizers sold on the market is mostly around 80 decibels, while the noise of good quality compressed atomizers should be within 65 decibels.
Noisy machines can generally be felt, and the manufacturer will not indicate the noise value of the machine. For machines with low noise, the manufacturer will mark it.
2. Vibration: vibration is accompanied by noise
Generally speaking, if the noise is loud, the vibration must not be small.
3. Heat: Along with the above-mentioned noise and vibration, it is heat generation.
Machines with high noise and vibration must generate more heat.
In fact, the above three items are all energy losses. Therefore, the nominal power of the compressed atomizer is not as large as possible.
For machines with high power but high noise (large vibration and heat), most of its energy is wasted.
4. Atomized particles: the size is directly related to the atomization effect. Smaller (less than 2.5μm) atomized particles can reach the lower respiratory tract and alveoli. Generally, the specifications provided by the manufacturer have a label indicating the size of the atomized particle, and the atomization Particle labeling generally involves the size of the drug particles, the average particle size (MMAD), the average median size (MMD), etc. The size of the atomized particles is affected by two factors: the compressor and the atomizing cup. The compressor provides air with a constant pressure. , The process of the atomization cup determines the level of excitation particle size.
Such as: "Nannuo Wuerkang" brand compressed atomizer, atomized particles (particle size) 80% 0.5～5μm
"Bairui" brand compressed atomizer, with an average median diameter (MMD) of 3.5μm, the percentage of particles smaller than 5μm is 68%
"Wuchang" brand compressed atomizer, with an average median diameter (MMD) of 3.5μm, the percentage of particles smaller than 5μm is 76%
5. Portability: the smaller the size, the better
When used at home, the size of the nebulizer is also a factor that household users need to consider. Smaller size means more convenient to carry. If you need to travel during the nebulization treatment, you need more attention.
6. Design and appearance quality
2. Atomization Cup
After the compressor meets the basic requirements, the quality of the atomization cup is particularly critical.
It is best to choose the atomization cup with patented technology. This information can generally be obtained from the product packaging.
