摘要：
An inhaler with a mixing channel (1) for producing an aerosol to be inhaled includes an outlet (9) at one end that can be inserted in the mouth of a person in order to inhale the aerosol that is produced at least one inlet (3) at its other end for drawing air into the mixing channel (1) and at least one injection zone (6) that lies between the inlet (3) and the outlet (9) and forms part of the channel wall. The injection zone (6) has at least one nozzle orifice (10) for supplying a liquid, especially a liquid drug, wherein the inner surface of the injection zone (6) is largely flush at least with that portion of the mean surface curvature (22) of the inner surface of the channel wall (11) that is adjacent to it on the inlet end. A possible height difference (17) between the inner surface of the injection zone (6) and that portion of the mean surface curvature (22) of the inner surface of the channel wall (11) that is adjacent to it is less than 1 mm or at most 100 μm or at most 20 μm.
