INHALER

摘要

An inhaler for inhaling pulverulent medicament from within a capsule comprises a chamber (24) within which the capsule is positioned with its longitudinal axis in the median plane of the chamber and thus generally parallel to the front (29) and rear walls (30) of the chamber, where the spacing between said front and rear walls is just greater than the diameter of the capsule and the diameter of the chamber is larger than the capsule's length. The device includes pins (21) serving as opening means to pierce the ends of the capsule while it is seated in a recess (25). Air inlets (26), chamber (24) and mouthpiece (27) are in such a spatial relation as to create a swirling or vortexing movement of the airflow which allows good capsule's emptying and powders to be finely dispersed. Chamber and mouthpiece inner walls can be of antistatic material.
