  • Patent number: 4854869
    Abstract: The present invention discloses a method for rotation of the nozzle of a dental syringe wherein that syringe is used to direct and deliver various agents including air and water. This method for rotation is facilitated by placement of an easily grasped component on the above mentioned nozzle. That easily grasped component is designed for use by the hand holding and operating that syringe while allowing that operating hand to remain in an operating position. The above mentioned component is fabricated separately from the above mentioned nozzle and subsequently attached to that otherwise functionally and aesthetically complete nozzle either temporarily or permanently. The present invention therefore provides for unilateral control over the direction, in relation to the handle of the syringe, of the agents as those agents exit that syringe.
