Inhaler, nebuliser, MDI… many terms are associated with this "inhalation device" system, which transforms inhalation solutions into the finest of mists for moist inhalation.
But what is what, and how is it all related?

The term "inhalation device" is used to refer to the totality of all components that, when assembled, enable aerosol production.


The compressor
In everyday language, the term inhalation device is often used to mean just the compressor. But the compressor on its own simply produces the compressed air that must then be transported to the component that actually generates the aerosol, the nebuliser.
The compressor has a motor, which can be powered by mains electricity or batteries.


The Nebuliser
This is the component that actually creates the aerosol, and so constitutes the heart of the entire system. Because it is essential for the nebuliser to match the needs of the user: To ensure that the aerosol is delivered to its intended destination and has the desired effect, for children and infants as well as for adults, the nebuliser must generate an aerosol spectrum adjusted as far as possible and with a droplet size optimised for its intended purpose. The liquid that is to be inhaled is poured into the nebuliser and then atomised to yield an extremely fine mist.
An opening is provided in the bottom of the nebuliser so that the compressed air can be introduced via the connection tubing. The aerosol produced in the nebuliser chamber is dispensed through the mouth opening and can be breathed in through an attached mouthpiece or a mask.


The connection tubing
The connection tubing connects the compressor to the nebuliser. Its design and length may vary depending on the inhalation device.
