Nebulizer: Classification, advantages and disadvantages of household nebulizers on the market
Every season, due to weather, environmental reasons or self-resistance, people are prone to various respiratory diseases, especially children and the elderly. The appearance of a household nebulizer can be used for atomization treatment at home, which solves various troubles for people to go to the hospital, saves time and avoids cross infection with other patients. Then it is inevitable to involve the purchase of household nebulizers. Then we will talk about the atomization principle of the household nebulizer in detail. What are the categories? And the advantages and disadvantages of each category.
The scope and basic principles of household nebulizers
Home nebulizers are mainly used to treat a variety of upper respiratory and lower respiratory diseases such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases in the trachea, bronchi, alveoli and chest disease. Nebulized inhalation therapy is an important and effective treatment for respiratory diseases. The nebulizer is used to atomize the liquid into tiny particles, and the drug enters the respiratory tract and the lungs by inhalation, thereby achieving painlessness. And quickly applied to the purpose.
Classification of household nebulizers
There are three main principles of atomization of household nebulizers, one is ultrasonic nebulizer, the other is compression nebulizer, and the other is mesh nebulizer. The ultrasonic nebulizer is the first generation nebulizer, the air compression nebulizer is the second generation nebulizer, and the micro mesh nebulizer is the third generation nebulizer.
The nebulizer of the ultrasonic nebulizer has no selectivity to the mist particles, so most of the produced drug particles can only be deposited in the upper respiratory tract of the mouth, throat, etc., and because of the small amount of deposition of the lungs, the lower respiratory tract diseases cannot be effectively treated. At the same time, due to the large amount of fog particles generated by the ultrasonic nebulizer, the atomization is fast, causing the patient to inhale too much water vapor, so that the respiratory tract is humidified, and the dry thick secretions of the bronchial tubes in the respiratory tract originally absorb the water and then expand, thereby increasing the respiratory tract. Resistance may cause hypoxia, and the ultrasonic nebulizer will cause the liquid to hang on the inner wall of the cavity, which is not effective for lower respiratory diseases, and requires a large amount of drugs, resulting in waste. Ultrasonic nebulizer is because of the large atomized particles, wasting liquid, easy to cough, has been scoured out of the market.
The gas compression air compression nebulizer uses compressed air to form a high-speed airflow through the small nozzle, and the generated negative pressure drives the liquid medicine together to be sprayed onto the obstruction, and splashes around at high speed to make the droplets become misty particles. The trachea is sprayed out. The air-compressed nebulizer is improved on the atomized particles on the basis of ultrasound, which is not easy to cause cough, but it is bulky, noisy, and easy to carry around, which is easy for children to use. obstacle.
The principle of micro-mesh nebulizer: through the vibration of the vibrator, the liquid is extruded through the hole of the nozzle-type mesh spray head, and is sprayed by the tiny ultrasonic vibration and the net spray head structure. The latest type, featuring both a compression nebulizer and an ultrasonic nebulizer, the spray method uses a small ultrasonic vibration and a mesh spray head configuration to spray, and is a family medical nebulizer for children with asthma. Easy to carry around anytime, anywhere. The micro-mesh nebulizer combines the characteristics of the ultrasonic nebulizer and the air-compressed nebulizer, and is superior to the two. It is small in size and can be carried around. The atomized particles are all below 5 microns, and the treatment is faster. The ultrasonic nebulizers on the market mainly refer to such nebulizers and are the most advanced nebulizers.
