Abstract
A device facilitating the inhalation of powdered medicaments from within a container. The device comprises a body having walls partially defining a chamber, an inlet port into the chamber for the entry of air, and a mouthpiece having a central through opening communicating with the chamber. A support member also partially defines the chamber and is manually movable relative to the body to convey a first portion of the container from (1) a first position spaced from the chamber to (2) a predetermined dispense position within the chamber with an open end of the first capsule portion uppermost so that airflow into the inlet port and through the chamber induced by suction at the mouthpiece will cause the powdered medicament in the first container portion to become entrained in the airflow; and an extractor is mounted for movement relative to the body to remove a second container portion and open the container prior to positioning of the first container portion at the dispense position.
