Abstract
A pulmonary delivery apparatus (10) comprising: a first chamber (15) adapted to thermally vaporise a quantity of a first liquid to form a relatively warm first vapour (B) and a second chamber (16) adapted to atomize a quantity of a second liquid without heating of the second liquid to form a mist of a relatively cold second vapour (A), and an outlet (30) via which, in use, a user can inhale a mixture of the first and second vapours. An active ingredient such as nicotine is provided in the second chamber and an inert liquid in the first chamber.

A pulmonary delivery device comprising:
- a first chamber adapted to thermally vaporise a quantity of a first liquid to form a relatively warm first vapour and a second chamber adapted to atomize a quantity of a second liquid without heating of the second liquid to form a mist of a relatively cold second vapour, and an outlet via which, in use, a user can inhale a mixture of the first and second vapours.
A pulmonary delivery apparatus comprising:
- a first reservoir for retaining, in use, a quantity of a first liquid;
- a first conveyor adapted to convey, in use, the first liquid from the first reservoir to a heater adapted, in use, to heat a quantity of the first liquid to form a first relatively warm vapour, a second reservoir for retaining, in use, a quantity of a second liquid under pressure and a pressure release valve adapted, in use, to propel a quantity of the second liquid to form a second relatively cold vapour, and an outlet through which, in use, a user can extract, by inhalation, a mixture of the first and second vapours from the apparatus.
