Abstract

Inhalation device (100, 1500) and associated method for facilitat-ing inhalation by a patient of powder medicaments contained in a receptacle (219).
The inhalation device has a chamber (210, 1510) for receiving the receptacle (219).
A ring (400) is circumferentially coupled to an inner surface of the chamber (210, 1510) to achieve a higher reproducible emitted dose of medicament from the re-ceptacle (219). The inhalation device (100, 1500) also includes an improved im-plement for puncturing the receptacle, requiring less force and experiencing fewer failures.
