There are two main atomizing principles used, one is an ultrasonic atomizer and the other is a compression atomizer.
Use ultrasonic principle to atomize medicine liquid.
The atomizer of the ultrasonic atomizer is not selective to the mist particles, so most of the drug particles produced 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 atomization, 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 enlarged 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 wall of the inner cavity, which has a poor effect on lower respiratory tract diseases, requires a large amount of medicine, and causes waste.
Air compression atomizer: Also called jet atomization, it is based on the Venturi spray principle. It uses compressed air to form a high-speed air flow through a small nozzle. The negative pressure generated drives liquid or other fluids to be sprayed onto the barrier together. Under the high-speed impact, the liquid droplets are sprayed to the surrounding area to make the droplets become mist-like particles and ejected from the outlet pipe.
The gas compression atomizer has the following advantages:
1.Efficient oil-free piston compressor, no cooling water required during atomization, daily maintenance-free, simpler and more convenient operation; original drug atomization, no dilution required, good clinical effect; almost no drug residue, high drug utilization ;
2. It is more convenient to operate and use. The product is equipped with a 2-meter trachea, which has a large room for movement and can be used for sitting and lying. The atomizing component is lightweight and easy to wear and hold. 3. The atomization uses the original medicine to atomize. The amount of nebulization inhaled during the treatment period is appropriate, which is not easy to cause the mucous membrane of the inner wall of the trachea to swell, causing the trachea to be blocked, the atomized particles are ultra-fine, and not easy to collide with the collision. Excellent effect, especially suitable for the treatment of lower respiratory tract diseases;
4. Pure mechanical products, the failure rate is extremely low, the maintenance cost is low, and the service life is long. Generally, it is normally used for 5 to 10 years.
