摘要：
Dry powder inhalers with rotatable piercing mechanisms facilitate the use of dose container assemblies having dose containers arranged in concentric rows. A piercing mechanism is operably associated with the dose container assembly and is configured to pierce sealants that seal a dose container. The piercing mechanism is rotatable such that it can serially alternate between the two rows of dose containers. The piercing mechanism includes a rotatable drum, an elongate piercing member, and a biasing member operably associated with the piercing member. The rotatable drum has an open end, an opposite closed end, and a cylindrical wall that extends from the closed end and terminates at the open end. The closed end includes an aperture formed therein in a location adjacent to the wall. The elongate piercing member is extended and retracted through the aperture to pierce the sealants of a dose container.
