This invention is for nasal adaptors for oral inhaler devices and methods of adapting an oral inhaler device with a nasal adaptor. The nasal adaptor of the present invention, in assembly with an oral metered dose aerosol inhaler converts an oral inhaler device to nasal delivery. The nasal adaptor in assembly with an oral inhaler device when in operation, simultaneously administers an inhalant to the nasal mucosa and down to the bronchial tree and lungs. In this manner a nasally delivered anti-inflammatory agent would travel down the same route as an allergen would - the nostril, nasal cavity, nasopharynx, trachea, bronchi and lung tissues.

Cette invention concerne des adaptateurs nasaux destinEs A des dispositifs d'inhalateurs oraux, et des procEdEs permettant d'adapter un adaptateur nasal sur un dispositif d'inhalateur oral. L'adaptateur nasal de la prEsente invention, lorsqu'il est assemblE avec un aErosol-doseur, transforme le dispositif d'inhalateur oral en vue d'une dElivrance nasale. L'adaptateur nasal, lorsqu'il est assemblE A un dispositif d'inhalateur oral et qu'il est en service, administre simultanEment un inhalant A la muqueuse nasale, jusqu'A l'arbre bronchique et aux poumons. De cette maniEre, un agent anti-inflammatoire dElivrE par le nez poursuivra le mEme chemin que le ferait un allergEne, à savoir la narine, la cavitE nasale, le rhino-pharynx, la trachEe, les bronches et les tissus pulmonaires.
