USPTO Abstract
The device comprises an actuator body 20 adapted to receive a medicament dispenser 40, and medicament delivery outlet means 23 through which medicament is delivered in an airstream in response to inhalation by a user, the outlet means being provided with an optimisation chamber 60 having a mouthpiece 61. The chamber has a volume in the range from 20 ml to 200 ml and is optionally fitted with baffle means serving to ensure that the larger droplets/particles are retained within the chamber so that only the smaller droplets pass through the oro-pharynx to enter the trachea etc. The actuator body and optimisation chamber may be engageable by a push-jet connection or may be pivotally connected to form a unitary device. <IMAGE>
