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 manifold is arranged such as to delay the emptying of the medicament powder from the blister pocket.
