Mixing channel for an inhalation device and inhalation device

An inhalation device comprising:

• a mixing channel having a longitudinal center axis, the mixing channel comprising:
• a first channel portion, comprising:
• an upstream end comprising an inlet opening, and
• a downstream end comprising a transition opening,
• a second channel portion, comprising:
• an upstream end comprising the transition opening, and
• a downstream end comprising an outlet opening,
• wherein the downstream end of the first channel portion comprises a wall that is orthogonal to the longitudinal center axis of the mixing channel, so that a step is formed between the first channel portion and the second channel portion;
• and
• a vibrating mesh nebulizer comprising a perforated membrane,
• wherein the vibrating mesh nebulizer protrudes into the first channel portion adjacent to the wall from a side of the mixing channel so that the perforated membrane is flush with the upstream end of the second channel portion on the side adjacent to the vibrating mesh nebulizer.

• and
• a vibrating mesh nebulizer comprising a perforated membrane,
• wherein the vibrating mesh nebulizer protrudes into the first channel portion adjacent to the wall from the side of the mixing channel so that a cross-sectional area of the second channel portion immediately downstream of the nebulizer is smaller than a cross-sectional area of the first channel portion immediately upstream of the nebulizer.
