CA 2450729

An inhaler device includes an air conduit including a mouthpiece and a dosing means adapted to provide a dose of powder to the air conduit for entrainment in the stream of air. In the area downstream from the dosing means the wall of the air conduit is provided with a secondary air inlet extending to the direction of the mouthpiece such that the entry of secondary air occurs over an extended length of the air conduit downstream from the dosing means.

L'invention concerne un système inhalateur comprenant un conduit d'air avec un embout buccal et un élément de dosage adapté pour fournir une dose de poudre au conduit d'air, destinée à être entraînée dans le flux d'air. Dans la zone située en aval de l'élément de dosage, la paroi du conduit d'air est munie d'une entrée d'air secondaire s'étendant en direction de l'embout buccal, de sorte que l'entrée d'air secondaire s'effectue sur une longueur étendue du conduit d'air, en aval de l'élément de dosage.
