Abstract
A multi-dose insufflator for the nasal administration of medicaments in fine or micronized powder form comprises a reservoir unit (34), a unit (60, 64) for withdrawing and metering the medicament contained in the reservoir unit, and an insufflation unit (42, 26) comprising a manually operated pump (42) for generating an air stream within a channel (26) for conveying an individual dose of medicament into the nasal cavity of the patient. The withdrawal and metering unit comprises a conveyor device (60) provided with at least one cup (64) for withdrawing a dose of medicament from the reservoir (34) and conveying it into an insufflation position. The cup (64) has a coaxial base hole (66) through which the air stream generated by the pump passes when the cup is in the insufflation position. The hole (66) has a size substantially smaller than the mouth of the cup (64) and such as to prevent the powder medicament falling through the hole, by virtue of the 'arching' effect.
