Portable nebulizer device

摘要

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.

主权项

1. A portable nasal nebulizer, comprising:
(a) a main canister comprising at least one air exit port, wherein the air exit port extends beyond a rim of the canister; and (b) an insert with a base that fits within the canister, wherein the insert comprises at least one fluid channel that fits over the air exit port, and further wherein the fluid channel is larger in diameter than the air exit port, thereby providing a small space between the outer surface of the air exit port and the inner surface of the fluid channel; and (c) a pressurized air supply source contiguously attached without tubing to the canister for introducing pressurized air through the air exit port such that the fluid is expelled as a mist through an exit hole in the fluid channel, wherein the insert comprises an extension protruding outwardly to the canister, wherein the fluid channel comprises a groove extending vertically along the exterior of the fluid channel to an aperture in the extension, said aperture creating a channel to the canister.
