1. A manifold for use in a medicament dispenser device for the delivery of medicament powder from an open blister pocket of each of plural blister packs, the manifold comprising a body, said body defining a chimney having only a single chimney inlet and plural chimney exits for directing airflow from said chimney inlet to said chimney exits; the body further defining a chamber having plural chamber inlets and a chamber exit, wherein the chimney exits and chamber inlets are arranged to form plural pairings of chimney exit and chamber inlet, each said pairing in use associated with an open blister pocket of a different one of said plural blister packs; wherein the chimney exit and chamber inlet of the plural pairings lie side-by-side each other such that when said open blister pocket of the associated blister packs are positioned adjacent thereto said airflow is directed from chimney exit to chamber inlet via the associated open blister pockets to entrain said medicament powder and enable transport thereof in the airflow from the chamber inlet to said chamber exit, and wherein one or more bleed holes are provided between the chimney and the chamber such that bleed airflow is able to be directed into the chamber to disruptively impact the airflow that transports the entrained medicament powder.
