Abstract
Described is a dry powder inhaler for inhalation of a dry powder composition. The inhaler includes an external housing that defines an internal passage. The inhaler also includes a mouthpiece, a compartment for holding a dry powder capsule or powder reservoir, and a powder fluidization and deagglomeration apparatus for directing airflow to the dry powder to generate airborne powder particles within the internal passage. When a user inhales through the mouthpiece, a first airflow pattern is generated that has a first airflow resistance, during which the fluidization and deagglomeration apparatus generates airborne dry powder particles within the internal passage. Upon reaching a threshold negative pressure value within the internal passage of the inhaler, a second airflow pattern is generated having a second airflow resistance that is lower than the first airflow resistance, which pulls the airborne dry powder into the user's lungs during the inhalation. Embodiments of elastomeric valves are also described.
