The present invention refers to a device aiming the administration, in humans and animals of therapeutical or diagnostic fluids, with the device already containing the fluid for injection, ready for use, eliminating the need for glass vials, ampules and conventional syringes. The device is constitued, basically, by a recipient (1), preferably made of plastic material, flexible, neutral not reacting with the fluid, pressure resistant, non elastic or little elastic for some applications, internally coated by a teflon film, with a conical or cylindrical shape in an upper view, oval in transversal cut-off, containing at its tapered portion (5) the terminal (6) with the fitting connection (7) and the tubular section (8) with the wing (9), heat sealed to the wall (3), reinforced by a pressure ring. For low injection volumes, the recipient (1) is placed between the plates (13) and (14), with the anterior tappered end of the upper plate (13) fitted under the upper catcher (18) fixed, by the pins (19) and (20), to the lower catcher (26) made part of the lower pressing plate (14). At the extremity of the upper pressing plate (13) there is the scale portion (21) with the injected volume indicator (22) that moves in the slot (23). Between the scale portion (21) and the extremity of the lower plate (14) it is placed the arm (27) connected to the foil (28). |
