Abstract

Injection device, having as its purpose the introduction of doses of fluid in an excluding body, the pungent action of any type of cannula; essentially it is characterized because it is constituted from a cylinder inside which a piston moves at the request of a certain pressure supplied by a source of energy in constant communication with the device, regulating the action of said pressure by means of the manual operation of a valve for opening and closing the chamber in the rear of the cylinder is established between the piston and the sealing plug of such a cylinder, provided that the piston in question is associated with a rod whose free end is housed inside a cylindrical and transparent chamber, of variable volume at will, to which the liquid contained in a bottle accedes cyclically and dosed through a valve installed in a radial appendix with which for that purpose it has a removable form tubular portion that is constituted in the channeling element of the liquid dose contained or in the transparent chamber to the application nozzle exclusively by contact to the receiving body of said dose, with the particularity that both the end of the plunger rod and the transparent chamber and the tubular portion that channels the dose of the fluid to the mouthpiece of outlet, they integrate a set coaxially related to each other and arranged inside a housing with a nut at one end to relate to and close the cylinder of the piston, while the opposite or free end has an external thread to receive the said nozzle as only element of application by contact on the receiving body of the dose of the fluid in question.
