Patent

CA 2418906

A powder delivery device for the delivery into a patient's nasal cavity of a physiologically active agent in powdered form. A closure restricts the unwanted ingress of moisture into the device when the device is not in use. The action of opening or closing this closure may be linked to charging an air reservoir with air and/or moving a fresh powder-containing receptacle into communication with a powder delivery passage.

L'invention concerne un dispositif d'administration de poudre servant à administrer un agent physiologiquement actif sous forme de poudre dans la cavité nasale d'un patient. Un moyen d'obturation (57) empêche la pénétration indésirable d'humidité dans le dispositif lorsque celui-ci n'est pas utilisé. L'action d'ouverture ou de fermeture de ce moyen d'obturation (57) peut être liée au chargement d'air dans un réservoir d'air et/ou à la mise en place d'un récipient contenant de la poudre fraîche (51) de sorte que celui-ci communique avec un passage (55) d'apport de poudre.
