Abstract: The invention relates to a mixing channel for an inhalation device, and in particular to a mixing channel with improved injection and mixing properties for injecting and mixing a liquid drug into an air flow streaming in the mixing channel, thereby producing an aerosol to be inhaled by a patient. One aspect of the invention relates to a mixing channel for an inhalation device, comprising an inlet opening, an outlet opening, and an injection zone located between the inlet opening and the outlet opening, wherein the injection zone has a longitudinal center axis, wherein the injection zone comprises (a) a built-in nebulizer, or (b) a detachable nebulizer, or (c) a member adapted to receive a detachable nebulizer, wherein the effective cross sectional area of the mixing channel in a plane perpendicular to the longitudinal center axis is smaller in the injection zone than upstream of the injection zone.

Abstract: The invention relates to a dosing system for an inhalation device which is capable of aliquoting a precise and accurately metered volume from a larger pre-defined fill volume. The dosing system comprises a filling chamber for receiving a liquid to be aerosolized, the filling chamber having a lateral wall, an inlet opening and an outlet opening with a closing means (11) for closing the outlet opening. The dosing system further comprises an overflow chamber surrounding the inlet opening of the filling chamber and a plunger which can be inserted, at least partially, into the filling chamber, and which sealingly contacts the lateral wall such as to displace liquid from said filling chamber upon insertion, and push a metered volume of the liquid out from the filling chamber through the outlet opening and feed it to the nebulizing means of the inhalation device.

Abstract: There is disclosed an adjusting device for a valve, especially a pressure control valve, comprising an axially displaceable control member on which a control spring acting on a valve body of the valve is supported. The control member is in rotational engagement with a catch connected to a handle for adjusting the control spring biasing. In accordance with the invention, the rotatable handle is connected to the catch such that first a radially projecting locking member is inserted in a recess in axial direction and subsequently is brought into an axial locking position by a relative displacement so as to lock the handle in axial direction with the catch.
