DRY POWDER MEDICAMENT INHALATOR HAVING AN INHALATION-ACTIVATED FLOW DIVERTING MEANS FOR TRIGGERING DELIVERY OF MEDICAMENT |
摘要 |
The present invention is an inhalation activated inhaler (10) having a primary inhalation passage (60), a secondary inhalation passage (90) disposed in communication with the primary inhalation passage, and a source of medicament. The primary inhalation passage has inflow inhibiting mechanism connected to a blocking plate (84) positioned to selectively block fluid flow in the secondary inhalation passage. As the user's inhalation reaches a defined rate, the flow inhibiting mechanism restricts flow through the primary inhalation passage, and moves the blocking plate to enable airflow through the secondary passage. Thus, as the user achieves a desired inhalation rate, the medicament is provided through the secondary inhalation passage, thereby optimizing the delivery of medicament to the lungs. |
