摘要：
An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.
