ABSTRACT:
An improved nasal inhalation system is provided for vaporizing a selected medicament or the like and for convenient inhalation of the resultant vapors. In one form, the inhalation system comprises a nozzle mounted at the discharge end of a source of air flow, preferably a heated air flow, wherein the nozzle is shaped to support a medicament-containing inhaler tube for flow-through passage of the air flow to produce medicinal vapors. A conveniently sterilizable vented adapter sleeve may be carried about the inhaler tube and/or mounted on the nozzle to prevent human contact with the inhaler tube and to limit the quantitative air flow to a person's nostrils. In an alternative form, a plurality of inhaler tubes are supported within a turret assembly mounted at the discharge end of the air flow source and rotatable to align a selected one of the inhaler tubes with an open discharge tube thereby permitting flow-through passage of air.
