ABSTRACT:
Inhalation device and associated method for facilitating inhalation by a patient of powder medicaments contained in a receptacle. The inhalation device has a chamber for receiving the receptacle. A ring is circumferentially coupled to an inner surface of the chamber to achieve a higher reproducible emitted dose of medicament from the receptacle. The inhalation device also includes an improved implement for puncturing the receptacle, requiring less force and experiencing fewer failures. The inhalation device also includes a means for indicating readiness.
