Abstract
A nasal nebulizer with a main canister for receiving fluid and an insert with a fluid channel includes a contiguous pressurized air supply source. The fluid channel may be a tapered tube overlapping an air exit port in the canister. The fluid channel may also comprise a common bell housing surrounding the air exit port above a base of the insert, which rests within the canister. The insert may include an extension projecting out to the canister and a vertical groove may extend down the fluid channel to a hole in the extension, which upon use helps create a vacuum that pulls in deflected fluid. The main canister includes a convex top surface around the periphery of an opening for a reservoir that receives fluids. The top surface extends downwardly to a generally rectangular opening that connects to the pressurized air supply source.
