How to buy a nebulizer mask?

With the rapid development of modern society, more and more medical devices are familiar to everyone. Home medical devices such as thermometers, sphygmomanometers, sleep ventilators, and oximeters have entered thousands of households. So about the nebulizer mask, everyone How much do you know? Next, let's get to know the medical nebulizer mask for household medical devices. The product indicators of the nebulizer mask include gas flow rate, pressure range, spray rate, residual liquid volume, whole machine noise, equivalent volume particle size distribution, etc. Among them, the most important performance indicators are the following three points:

Here is the content list:

l The gas flow of the nebulizer mask.

l The spray rate of the nebulizer mask.

l Equivalent volume particle size distribution.

The gas flow of the nebulizer mask.

The gas flow refers to the flow rate of the compressed air gas of the compressor, generally in kPa and mmHg. The value of value determines the power of the nebulizer mask to emit a fog. A nebulizer mask with insufficient gas flow may cause insufficient power and insufficient fog, which will affect the spray effect.

The spray rate of the nebulizer mask.

Refers to the amount of mist produced by the nebulizer mask per minute, generally in mL/min. The size of the spray rate determines the speed of the nebulizer mask spray. If the spray rate is too low, it may lead to low mist output and affect the treatment effect. Under normal circumstances, 1ml of the drug needs 3-5 minutes of atomization time. For infants and children, it is difficult to sit still for a long time, and it is better to choose a machine with an atomization speed >=0.3ml/min. The general atomization speed of the handheld nebulizer mask is >=0.17ml/min. Under the same dosage, it is 1 times slower than the desktop compressed nebulizer mask, but for young children, it is not the faster the better. the trachea of young children is relatively immature and sensitive. For most families, it is recommended to buy a desktop compressed nebulizer mask, many nebulizer masks can adjust the fog speed.

Equivalent volume particle size distribution of the nebulizer mask.

The diameter of a spherical particle of the same substance having the same volume as the actual particle is called the equivalent volume particle diameter. The particle diameter and distribution of the aerosolized drug in the nebulizer mask affect the therapeutic effect of the drug. The smaller the particle diameter of the nebulizer mask, the finer the spray, and the more particles below 5um, the better the distribution. The efficacy of atomization depends on the size of the atomized particles. Particles with a diameter of fewer than 5 microns can reach the bronchi and alveoli, and particles with a diameter of more than 5 microns can only reach the oropharynx, and the atomized particles are too small. If it is less than 1 micron, it will be exhaled if it cannot be deposited in the lungs, and the nebulizer mask cannot achieve the therapeutic effect.
