Nebulizer.

Explanation:

Nebulizer is a device which turns liquid medicine into a mist in order to treat certain conditions, for example, asthma. They can be both electric or battery-run. They can be either portable and small or large, which are meant to sit on the table and be plugged into the wall. They are both made out of the base that holds an air compressor, a small container that's used for liquid medicine and a tube that connects then together. Above the container, there is a piece that's used for the mouth or a mask that the person will use to inhale the mist.
