Abstract: A microstructured passage module for aerosol generator is provided. The module includes a plate overlaid by a cover thus forming a compartment, an entrance for a liquid and an exit. The plate includes a plurality of walls parallel to each other over its entire width so as to define a plurality of passages therebetween. Moreover, a plurality of pillars protruding from the plate are distributed in at least section of the passages. A column is disposed proximate to the exit and blocks a substantial part thereof, leaving longitudinal aisles for the liquid to flow towards the exit. The liquid flows through the compartment from the entrance to the exit such that an aerosol is produced. A distance between two adjacent pillars is D and the longitudinal aisle has a width W. The D and the W are specifically configured such that the aerosol has a predetermined MMAD.

Abstract: A locking mechanism for an aerosol drug delivery device includes a first housing, a second housing, a screw and a fastening member. The first housing has a contact portion and a fastening space formed beside the contact portion. The second housing is rotatably connected with the first housing and is capable of rotating relative to the first housing along a rotation axis. The screw is rotatably connected with the second housing and is capable of rotating relative to the second housing along a central axis parallel to the rotation axis. The fastening member is movably connected with the screw and capable of being driven by the screw to move toward the contact portion. The fastening member includes a fastening portion capable of being displaced when contacting with the contact portion and entering into the fastening space to limit the relative rotation between the first housing and the second housing.
