Abstract

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.

16. The nasal adaptor of claim 15, wherein said circular flange is contiguous with a rim which fits snugly over the remainder of the lower arm of said housing and is partially indented in order to abut the upper arm of said housing, when in assembly.

33. The method of assembling the nasal adaptor of claim 12 with an oral inhaler device comprised of a housing and canister containing inhalant, said housing having an upper arm and a lower arm, which lower arm is capable of detachment at a point along the lower arm, by detaching the lower arm and inserting the first end of said nasal adaptor into the remaining lower arm of said housing.
