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.
