A nebulizer comprises a gas exit, at least one outlet adjacent to the gas exit, and a deflector for deflecting a stream of gas issuing from the gas exit over the at least one outlet for drawing a substance to be atomized from it, and for atomizing the substance in the gas. The deflector defines first and second profiles, and the atomizer has an atomizing configuration in which the first profile of the deflector lies in the stream of gas for atomization, and non-atomizing configuration in which the second profile of the deflector lies in the stream of gas without atomization of the substance.

Nebulizer

An atomizer for dispensing a powder or liquid product which is atomized by a stream of compressed air and further has either (1) means to prevent or stop the product from atomizing in response to a positive pressure in the atomizer or (2) a secondary reservoir located between the product reservoir and a product outlet from which the product is atomized, said secondary reservoir is in fluid connection with a second chamber, the second chamber being operable in response to a positive pressure in the atomizer to drive fluid from the secondary reservoir.

Atomizer

An arrangement for delivering a drug aerosol comprises a sensor (3) which detects turbulent air flow during inhalation and causes the nebulizer (8,9,10,11,12,13) to generate the aerosol only during the inhalation phase of the breathing cycle. Airflow is diverted from the sensor during exhalation.
