Description

[Technical field]

[0001] The utility model relates to a medical atomization device. [Background technology]

[0002] Nebulizer is a commonly used therapeutic instrument in clinical practice. It produces atomized drug particles at a uniform speed during the treatment process. The patient inhales the drug particles into the lungs through breathing, thereby achieving the purpose of treatment. There are many nebulizers on the market, such as the one disclosed in the Chinese patent application number CN202010548410.5 and the name of the atomizer mask, which usually includes an atomizer cup, a mask body and an infusion tube. The atomizer cup and the mask body are connected by the infusion tube. The process of generating particles by this type of nebulizer is uniform, but the airflow entering the lungs during the breathing process is not uniform. The atomized drug can only be used when inhaling, which causes a huge waste of drugs, and the drug particles are scattered into the air, causing environmental pollution.

[0003] Therefore, the present invention is just produced based on the above shortcomings. [Utility Model Content]

During atomization treatment, the mask 5 fits the human face, and the atomized medicine liquid produced by the atomizer 1 will flow into the aerosol storage container 3 through the output pipe 2 for storage.

The atomizing head 12 is arranged at the end of the conveying body 131 and is connected to the mixing chamber 134. The air inlet pipe 9 is connected to a high-pressure air source, and the high-pressure airflow can continuously enter the air inlet channel 132 from the air inlet pipe 9, and be ejected from the atomizer head 12 after passing through the mixing chamber 134; when the high-pressure airflow passes through the mixing chamber 134 at high speed and is ejected from the atomizer head 12, negative pressure is generated.
