摘要:
A breath-actuated dry powder inhaler (1, 201), said inhaler (1, 201) comprises a substantially flat housing formed by a stack of substantially flat elements (16), said flat elements (16) including a plate (19) ) lower, an intermediate plate (18) and an upper plate (17), said flat elements (16) are parallel to each other, at least one projection plane element (19) being provided (20a-g, 220a-k) and an opening, which in the stack forms a substantially circulating disk-shaped air circulation chamber (2) to deagglomerate the entrained powder medicine using the energy of the inspiratory air stream, a plurality of channels (7, 207) of air supply, a supply region air for a powder flow and an inhaler discharge channel (12) (1, 201), the chamber (2) has a substantially polygonal side wall (3) extending around a central axis (4) between the upper and lower walls of the chamber (2), the central axis (4) extending transversely to the lower plate (19), the height of the chamber (2) is smaller than its diameter, the plurality of channels (7, 207) of Air supply are arranged around the circumference of the chamber (2), whose channels (7, 207) extend from an air inlet (27) and channels (7, 207) enter the chamber (2) substantially tangential to its side wall (3), the housing comprises a dust channel (7a, 207a) that extends through a dose delivery region (8) of inhaler dust (1, 201) to the chamber (2), whose dust channel (7a, 207a) enters the chamber (2) substantially tangentially to its side wall (3), in addition the chamber (2) comprises an air outlet (9) extending axially from an opening (10) discharge and connect to a discharge channel (12) that extends to a nozzle (13), in which the discharge channel (12) is substantially transversely connected at the air outlet (9) of the chamber (2), characterized in that the inhaler (1, 201) comprises a single air circulation chamber (2) and because the polygonal side wall (3) comprises at least six segments of straight line (5a-5g, 205a-205k)
