| 摘要 |
The invention relates to a device (1) for inhalation of at least one air stream carrying a dose of medicament powder (2). The device comprises a flow passage (4) passing a powder-containing cavity (5). A part of said flow passage (4) propagates along a flat surface region (7). The flat surface region (7) comprises a cavity opening (20) into said powder- containing cavity (5). The passing of an air stream along said flat surface region (7) and outside said cavity (5) generates an eddy in the cavity (5) and the generated eddy contributes to deaggregation of the powder (2) in said cavity (5) and emptying of the powder (2) from said cavity (5). Furthermore, the invention relates to the use of a shear driven cavity principle on such a device (1) and a method of releasing medicament powder (2). |
