The nebulizer atomizes the test solution. The nebulizer is an important part of the atomization system, and its performance has a significant impact on the precision of the determination and chemical interference, among other things. Therefore, the atomizer is required to spray stable, fine and uniform droplets and high atomization efficiency.
According to different purposes, there are many types of atomizers. Air humidifier: humidifier used to humidify the air is a type of nebulizer; medical nebulizer: a device used to treat upper respiratory tract diseases, belonging to the medical device; other types of nebulizers: such as hair styling with hair spray equipment, electronic cigarette composition of one of the important structure, used to atomize the tobacco oil.
Ultrasonic nebulizer
Ultrasonic nebulizer: the use of ultrasound principle, the medicine will be atomized. The nebulizer of the ultrasonic nebulizer is not selective to the fog particles, so most of the drug particles produced can only be deposited in the upper respiratory tract such as the mouth, throat, etc., and due to the small amount of deposition in the lungs, it can't effectively treat lower respiratory tract diseases.
At the same time, due to the ultrasonic nebulizer produces a large fog particles, atomization fast, resulting in patients inhaling too much water vapor, so that the respiratory tract wetting, the respiratory tract originally partially blocked the bronchial tubes of the dry and thick secretions to absorb the water and then expand, increase the respiratory tract resistance, may produce a lack of oxygen phenomenon, and ultrasonic nebulizers will make the medicine knotted into a droplet hanging on the wall of the inner chamber, the lower respiratory tract diseases, the effect of poor, on the Drug demand, resulting in wasteful phenomenon.
