There is a medical machine in the hospital that sprays small people. What's it called? Can you buy it?

It is sold in many places, medical device companies and online. Good luck.

According to the brands, Du Ya (who makes humidifiers), Jiahua and Yuehua are well-known.

There are gas compression and ultrasonic waves, but they are basically between 200 yuan and 500 yuan, and ultrasonic waves are a little more expensive.

Foreign countries are expensive ~
