The invention relates to the field of inhalation methods and inhalation devices for liquids. In particular, the invention relates to an inhalation method using an inhalation device adapted to separately eject at least two liquid compositions each having different properties, and to a method for the generation of an aerosol of at least two medicinal formulations by means of such inhalation device.

Aerosol delivery of at least two liquid compositions

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to a nebulizing nozzle to be used in such an inhalation device, as well as a method for fabrication of such a nozzle. A nozzle for an inhalation device for nebulizing a liquid into a respirable aerosol has a nozzle body () which has a front end (B) and which comprises at least two ejection channels ('), each channel (′) having an channel exit (A,A′), wherein the ejection channels (′) are arranged such as to eject liquid along respective ejection trajectories which intersect with one another at a collision point. The nozzle is characterized in that at least one recess () is provided at the front end (B) in which the channel exits (A,A′) are positioned. Disclosed is also a method for the fabrication of a nozzle body as defined above, use of such a nozzle in an inhalation device for nebulizing a liquid, and an inhalation device for nebulizing a liquid into a respirable aerosol, comprising such a nozzle.

Spray nozzle for an inhalation device

An inhalation device including a housing; a reservoir for storing a liquid; a pumping unit including a riser pipe; a hollow cylindrical part having an interior space and being linearly moveable on the riser pipe, the pumping chamber fluidically connected with the reservoir; a nozzle connected liquid-tight to a downstream end portion of the riser pipe; wherein the linear relative motion can be effected by a relative rotation around a rotational axis of a rotatable part with respect to a counterpart converting the relative rotation into the linear relative motion by a gear mechanism comprising at least one cam surface having a first section and a second section, a spring for the storage of potential energy, wherein the cam surface has, between the first section and the second section, a third section of constant height upon which no linear relative motion occurs while the counterpart slides along it.
