Zusammenfassung:	A nasal delivery device can include air-receiving section that has a first passageway therethrough to allow air to pass through the air-receiving section, a powder-reservoir receiving section sized to receive a powder reservoir, and a powder-delivery section that has a second passageway therethrough to allow aerosolized powder from the powder reservoir to pass through the powder-delivery section. The first passageway can have a first end and a second end, with the first end being further from the powder-reservoir receiving section and the second end being at or near the powder-reservoir receiving area. The second end of the air-receiving section can include a flattened region so that air exiting the air-receiving section has a generally flattened profile.
