DEVICE FOR INHALATION

摘要

The device for inhalation of a powdery, pharmacologically active drug consists of a supply container (3) for the drug (4), a manually actuated metering unit for providing a portioned-off quantity of inhalation substance which is picked up by the air current drawn in during inhalation and is swirled, an air inlet channel (9), a swirl chamber (W), and a connection channel (8) between the swirl chamber (W) and the metering unit, as well as a mouthpiece channel issuing from the swirl chamber (W). The metering unit here consists of a metering drum (D) which has, in its interior (5), a supply container (3) for the drug. Furthermore, the air inlet channel (9) and the connection channel (8) are arranged in such a way that they run towards each other in a V-shape. During a metering procedure, a portioned-off quantity of drug for inhalation present in the shape of a dome is provided in each case at the apex of the two air channels (8) and (9) running towards each other in a V-shape.
