Abstract

An inhalation device for inhalation of a medicament from an openable capsule, the device comprising: a housing unit including a dispersing chamber therein; at least one air inlet in the housing unit through which air may be admitted into the dispersing chamber during inhalation by a person; a mouthpiece removably attached to the housing unit and in communication with the dispersing chamber; a mesh provided between the dispersing chamber and the mouthpiece to prevent entry of the capsule into the mouthpiece while permitting medicament from the capsule to travel to the mouthpiece; characterized by: a port in the housing unit for inserting a medicament capsule there through such that a first portion of the capsule is captured in the port and a second portion of the capsule extends into the dispersing chamber; and an impinger located in the housing unit and adapted to engage the second portion of the capsule to open the capsule and thereby permit escape of the medicament from the capsule into the dispersing chamber.
