English name
nebulizer
use
Medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli, and chest cavity. Nebulized inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. A nebulizer is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs by breathing inhalation, so as to achieve painlessness. , The purpose of rapid and effective treatment.
type
There are three main atomization principles used, one is an ultrasonic atomizer, one is a compressed atomizer, and the other is a mesh atomizer.
Ultrasonic nebulizer: Use the principle of ultrasonic to atomize the liquid medicine.
The nebulizer of the ultrasonic nebulizer is not selective to the mist particles, so most of the drug particles produced can only be deposited in the upper respiratory tract such as the mouth and throat, and because the amount of deposits in the lungs is small, it cannot effectively treat lower respiratory tract diseases. At the same time, due to the large and fast atomization produced by the ultrasonic nebulizer, the patient inhales too much water vapor, which humidifies the respiratory tract. The dry and thick secretions in the respiratory tract that originally partially blocked the bronchus swell after absorbing water and enlarge the respiratory tract. Resistance may cause hypoxia, and the ultrasonic atomizer will cause the liquid medicine to form drops and hang on the inner cavity wall, which is not effective for lower respiratory tract diseases, and the demand for medicine is large, resulting in waste.
compression
Air compressed atomizer
Air compression atomizer: also called jet atomization, based on the principle of Venturi, it uses compressed air to form a high-speed airflow through a small nozzle, and the negative pressure generated drives the liquid or other fluids to be sprayed onto the barrier. , Splashing to the surroundings under high-speed impact to make the droplets become mist-like particles ejected from the air outlet pipe.
The gas compression atomizer has the following advantages:
1. High-efficiency oil-free piston compressor, no cooling water required during atomization, daily maintenance-free, simpler and more convenient operation; original drug atomization, no dilution, good clinical effect; almost no drug residue, high drug utilization rate ；
2. It is more convenient to operate and use. The product is equipped with a 2-meter trachea, which has a lot of room for movement, and can be used for sitting and lying. The atomization component is light and easy to wear and hold;
3. The atomization uses the original medicine atomization, the amount of atomization inhaled within the relative treatment time is appropriate, it is not easy to cause the inner wall of the trachea to swell, cause the trachea to block, the atomized particles are ultra-fine, and are not easy to collide and combine, and the human body is comfortable to inhale , And can enter the bronchus, lungs and other trachea, the clinical effect is excellent, especially suitable for the treatment of lower respiratory tract diseases;
4. Purely mechanical products, with extremely low failure rate, low maintenance cost, long service life, and normal use for 5 to 10 years.
Net atomizer
Through the up and down vibration of the vibrator, the liquid medicine is squeezed out through the holes of the nozzle-type net spray head, and sprayed by the micro ultrasonic vibration and the net spray head structure.
