A drugs transdermic dosing device (1), comprising a body or fixed portion (2) with a piston (33) and a nozzle (37) for dosing a drug, a movable or swiveling portion (4), associated with said fixed portion (2) and usable to set the dose of drug, and at least one button (22) for activating the device (1 ), which is connected with a punch (31) acting on said piston (33). A bushing (3) is placed between said fixed portion (2) and said movable portion (4), said bushing (3) having a seat (24) for housing at least one cylindrical ring (5), which is divided into a numbered lower portion (25) and an upper portion (26) having a dowelling surface and which is activable from the outside. The cylindrical ring (5) has a lower base, where there are formed a plurality of first conical imprints (28), which are adapted to be engaged by a first probe (7) mounted in the fixed portion (2), and an upper base, where there are formed a plurality of second conical imprints (38), which are placed axially with respect to the first conical imprints (28) and which are adapted to be engaged by a second probe (9), mounted within said movable portion (4) and placed parallel and opposite to said first probe (7). |
