The present invention relates to a device for the intranasal administration of powdered medicaments. Specifically, the device comprises a cavity where the medicament to be dispensed is placed. As the patient inhales, air is drawn into the cavity through at least two air inlet slots. The arrangement of the air inlet slots cause the air to rotate within the cavity. The swirling motion of the air disperses the medicament within the cavity and picks up the powder. The required amount of powder is drawn up an outlet nozzle in a rotating column of air and out through a nasal adapter. |
