WIPO Patent Application WO/2018/082699

Kind Code:

A1

Abstract:

A microstructured passage module (1) for aerosolizer (90) is disclosed. The module (1) includes a plate (10) overlaid by a cover, an entrance (102), an exit (104), a plurality of protrusions (5) and a plurality of pillars (4). The protrusions (5) and pillars (4) project from and are integral parts of the plate (10). Further, the plate (10) can be divided into a first zone proximate to the entrance (102) and a second zone proximate to the exit (104). The protrusions (5) are arranged into parallel rows in a direction from the entrance (102) to the exit (104) and form parallel passages (18) therebetween in the first zone for the liquid to flow along. The protrusions (5) in each column (52) are spaced from one another by tunnels (17). The pillars (4) are interposingly disposed in the second zone and define certain channels (16) therebetween. Moreover, a plurality of pillars (4) further disposed in the passages (18) increase a flow resistance for the liquid flowing through the passages (18).
