氧气雾化吸入法是利用高速氧气气流，使药液形成雾状悬液，再随呼吸吸入呼吸道，达到治疗的目的。基本原理是利用高速氧气流通过毛细管口并在管口产生负压，将药液由相邻的管口吸出，所吸出的药液又被毛细管口高速的氧气流撞击成细小的雾滴，成气雾状喷出，随患者呼吸进入呼吸道而达到治疗的作用  。
Oxygen atomization inhalation method is to use high-speed oxygen air flow to form a mist like suspension of the liquid medicine, and then inhale it into the respiratory tract with the breath, so as to achieve the purpose of treatment. The basic principle is to use the high-speed oxygen flow to pass through the capillary port and generate negative pressure at the pipe port, and suck out the medicine liquid from the adjacent pipe port. The medicine liquid sucked out is hit by the high-speed oxygen flow at the capillary port into a small droplet, which is ejected in the form of an air mist, and then enters the respiratory tract with the patient's breath to achieve the therapeutic effect.
