Abstract: A portable heated mist inhaler has a body, a supply tank of liquid, an atomizer for atomizing the liquid, and a thermostatically controlled heated nozzle. The supply tank feeds liquid to the atomizer. The atomizer creates a stream of mist from the liquid and entrained surrounding air. The mist is heated inside the nozzle so that it will be comfortable for the user. The portable heated mist inhaler has a battery which powers the atomizer and the heated nozzle.
