Abstract: A novel device and method for the efficient, regular and highly maneuverability administration of medical liquids, especially anesthetics. The system of the present invention includes a light-weight, hand-held injection device which is connected to an operating pedal and a control unit. The control unit stores a number of preprogrammed injection procedures having specific injection flow rates and volumes, and provides the user with the ability to create and store a plurality of user-defined procedures. The control unit and injector allow precise selection, control and monitoring of the injection flow rate and volume. The operating pedal provides “hands-free” control of the procedures, as well as a means to select various sub-procedures, such as an Aspiration mode, Introduction mode, or Preparation mode, in addition to the Injection mode.

Abstract: An advanced osseous or periosseous dental anesthetic method involving apparatus for motorized injection of anesthetic liquids at a low and extended volumetric rate. The anesthetic is injected at a low and extended volumetric rate adjacent or directly into the osseous without pain or danger to the surrounding tissue.
