Abstract: A manifold for a medicament dispenser, where a manifold body defines a chimney with an inlet and an exit for directing airflow from the inlet to the exit, and a chamber with a chamber inlet and chamber exit. The chimney exit and the chamber inlet lie side-by-side each other such that when the open blister pocket of the blister pack is positioned adjacent thereto, the airflow may be directed from the chimney exit to the chamber inlet via the open blister pocket to entrain the medicament powder, enabling transport of powder in the airflow from chamber inlet to chamber outlet. The chimney creates turbulence in the airflow at the open blister pocket. The manifold comprises plural chimney exits, located at an angle relative to each other of from 150° to 30° such that, in use, plural airflow jets are directed at different and conflicting angles towards the open blister pocket.

Abstract: There is provided a manifold for use in a medicament dispenser device for the delivery of medicament powder from an open blister pocket of a blister pack. The manifold comprises a body, the body defining a chimney having a chimney inlet and a chimney exit for directing airflow from the chimney inlet to the chimney exit; the body further defining a chamber having a chamber inlet and a chamber exit. The chimney exit and said chamber inlet lie side-by-side each other such that when said open blister pocket of said blister pack is positioned adjacent thereto said airflow may be directed from the chimney exit to the chamber inlet via the open blister pocket to entrain said medicament powder and enable transport thereof in the airflow from the chamber inlet to said chamber outlet. The chimney is arranged to create turbulence in the airflow at the open blister pocket.

The chamber is arranged to promote break up of said entrained medicament powder by exposing the entrained medicament powder to one or more regions of differential force during its transport through the chamber.
