  • DRY POWDER INHALER
    Publication number: 20090084379
    Abstract: An dry powder inhaler is disclosed. The dry powder inhaler is designed so that a user's breath vacuums the dry powder from a well within the housing and directs the powder in a direct path to the user. This design prevents impaction and agglomeration of powder within the inhaler. A flow restrictor may be added within the inhaler to increase turbulence and thus increase dispersion of powder within the air inhaled by the user.
