APPARATUS FOR SEPARATION OF DRY INHALER POWDER INTO COMPOSITE PARTS Russian patent published in 2007 - IPC A61M15/00 

FIELD: devices for separating of dry medicinal powder into composite parts.

SUBSTANCE: apparatus has cylindrical air circulation chamber having height smaller than its diameter, and at least two air feeding channels extending into chamber tangentially to its cylindrical wall and positioned substantially on opposite sides of said wall for creating circular air flow within chamber. Air channels have inlet openings of different sizes or single inlet opening may be alternatively used, said opening being divided so that one passage intersects dose measurement zone or inhaler dose feeding zone in order to provide suction of powder through said passage with the help of air in an amount equal to one inhaler dose into circulation chamber, and other passage serves as bypass channel leading into circulation chamber.

EFFECT: increased efficiency by providing acceleration of particles and creation of more symmetric configuration of air flow within chamber.
