Three types of nebulizer
Date:2019-12-25
 1. Ultrasonic nebulizer

The nebulizer of the ultrasonic nebulizer is not selective to the mist particles, so most of the drug particles generated can only be deposited on the upper respiratory tract such as the mouth and throat, and because the amount of deposition in the lungs is small, it cannot effectively treat lower respiratory tract diseases. At the same time, due to the large mist particles generated by the ultrasonic nebulizer and the rapid nebulization, the patient inhaled too much water vapor and humidified the respiratory tract. The dry and thick secretions that originally partially blocked the bronchus in the respiratory tract swelled after absorbing water and expanded the respiratory tract. Resistance may cause hypoxia, and the ultrasonic nebulizer will cause the medicinal solution to form drops of water and hang on the inner cavity wall, which has a poor effect on lower respiratory tract diseases and a large demand for drugs, causing waste.

2. Net nebulizer

The principle of the net nebulizer: through the up-and-down vibration of the vibrator, the medicinal solution is squeezed out through the holes of the nozzle-type net spray head, and the use of tiny ultrasonic vibration and the structure of the net spray head is used for spraying. This latest type has the characteristics of both a compression nebulizer and an ultrasonic nebulizer. The spray method is to use tiny ultrasonic vibration and a mesh spray head structure to spray. It is a home medical nebulizer for children with asthma. It is convenient to carry and use anytime, anywhere.

3. Compression nebulizer

The gas compression air compression nebulizer uses compressed air to form a high-speed air flow through a small nozzle. The negative pressure generated drives the medicinal solution to be sprayed onto the obstacle together. Under high-speed impact, the droplets of the sprayer are turned into mist-like particles. The trachea squirts.
