ABSTRACT:
An improved dental syringe for injecting pressurized warm water and air into the oral cavity of a dental patient. A syringe, having an elongate tip for guiding water and air under pressure into a patient's oral cavity and atomizing the water with the air, a body to which the tip is attached including pushbutton controls for regulating the water and air, and a source of pressurized water and air, is provided with a novel flexible, disposable sanitary tip of unitary construction, and the tip is attached to the body by a new, rapidly-operated mechanism which permits the tip to be removed merely by rotating a fastener approximately one half-turn and pulling the tip away from the body, and to be similarly attached by reversing the procedure. The invention also provides a simplified, easily removed three-piece pushbutton control mechanism for regulating the water and air, and a novel flexible conduit leading from the source of water and air to the syringe body, the conduit having a heating element adjacent water and air channels therein for heating the fluids to prevent any significant time delay from actuation of the syringe to arrival of warm fluid at the patient end of the tip.
