First, it is the ultrasonic nebulizer. The nebulizer of the ultrasonic nebulizer does not have the same selectivity for 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, but because the amount of deposition in the lungs is very small, it cannot be effectively treated. Respiratory diseases. At the same time, because the ultrasonic atomizer produces large mist particles and atomizes quickly, the patient inhales too much water vapor, which humidifies the respiratory tract and fails to absorb the medicine well.
The second is the net atomizer. The principle is to use the instrument to vibrate up and down, so that the liquid is squeezed out of the nozzle in the spray can-like net spray head, and then the extremely small ultrasonic vibration and nozzle are used to construct Into a spray. This is also one of the latest types of many types of medical atomizers.
Finally, there is the gas compressed air compressed atomizer. The principle of this kind of atomizer is to use compressed air to form a high-speed airflow through a small nozzle, and the generated air pressure drives the liquid medicine to be sprayed onto the obstruction together, so that it uses the high-speed air pressure to hit the droplets and splash around at the same time. The purpose of turning into mist-like particles is to make the medicine particles ejected from the air outlet pipe. These are several common types of medical atomizers in society.
