ABSTRACT:
An auxiliary device is provided for use with a metered-dose aerosol device. The auxiliary device comprises a chamber having an inlet adapted to receive the metered-dose aerosol device, and an outlet. A mask adapted to communicate with the nose and/or mouth of an infant or young child communicates with the chamber outlet via a first valve which permits the infant or young child to inhale aerosol-carrying air from the chamber, and communicates with atmosphere via a second valve permitting exhalation therethrough. The distance between the chamber inlet and the chamber outlet is such that the mass percentage of aerosol particles having a diameter of from 1.0 microns to 5.0 microns is substantially a maximum at the chamber outlet, and the volume of the chamber is from 200-500 ml.
