Abstract

A syringe nasal sprayer includes an elongate barrel having an open proximal end, a chamber for retaining fluid and a tip portion extending from a distal end of the barrel having a passageway therethrough communicating with the chamber. A
stopper is slidably positioned in fluid-tight engagement inside the barrel. An elongate plunger rod projects proximally from the stopper and extends outwardly from the open proximal end of the barrel. A spray nozzle extends outwardly from the tip portion and includes a conduit therethrough in fluid communication with the passageway. A distal end of the nozzle includes a spray aperture in fluid communication with the conduit. The nozzle also includes an internal valve for allowing liquid under pressure in the chamber to flow distally through the conduit and through the aperture while preventing unpressurized liquid in the chamber from flowing through the aperture.
