Abstract: The method for dispensing of a liquid, viscous, pasty, powdery, or gaseous product by means of a dispensing device (100) adapted to being held and manipulated by a single hand of the user U comprises: Taking a dispensing device (100); Selecting a connection tip from a tip assortment A through G, each of them having a previously defined function; Securing the tip chosen from the tip assortment A through G inside the dispensing device (100); Selecting a mode among the different modes of the control program; Positioning the dispensing device (100) in the work zone; Activating a control button (400); Releasing the control button (400); Removing the selected tip from the dispensing device (100);

Abstract: A portable medical device (D) for using an interchangeable connecting tip is disclosed. The device includes an elongated body and can be carried and used with one hand. The body is configured at one end to removably receive said connecting tip, which includes a reservoir and a piston associated with a rod. The device also includes an actuator ensuring the movement of a first shaft acting on a second end of the rod. The reservoir can be an empty reservoir to be filled, and the first shaft is equipped to be temporarily fixed to the second end of the rod associated with the piston so as to, on the one hand, transmit by means of the first shaft, forward and reverse longitudinal movement of said piston so that the user can, fill and empty said reservoir.

Abstract: Disclosed is a connection tip for a dental device for universal application, including a hollow cylindrical body including, on the one hand, a fastener for its retention inside the dental device and, on the other hand, a recognition unit which are activated during the connection of the tip inside the device and allow initializing predetermined control unit depending on the profile of the connection tip.

Abstract: A dental electronic device for universal application with controlled thrust includes an elongated body inside which is positioned a battery supplying an electric motor for driving a thrust pin arranged to cooperate with a connection tip selected from a range of connection tips and being locked inside the elongated body of the pen, each tip including a fastening element for retaining the fastening element inside the elongated body and a recognition element which is activated during the connection of the tip and allowed to initialize one of the control programs previously integrated in an electronic card housed inside the body and connected to a control button placed on an outer face of the elongated body for controlling the electric motor based on the given control program of the tip so as to drive the tip.
