A device for applying intravenous injections and serums with a single puncture, characterized in that it consists of a fitting of plastic material or the like, whose front part is conical and has a hypodermic needle embedded therein; the central part of said fitting has a projection or lug in the direction perpendicular to the base part or fitting which, on its rear part, adopts a tubular shape. Said fitting has a hole for its entire length, an orifice that is of different diameter, depending on whether it communicates with that of the needle, at one end or the other, to the outside. In the front conical part, another similar piece is attached, with the only modification of which, the cone extends, forming a very thin tube in which the hypodermic needle is housed, until only its tip protrudes. In the rear tubular part of the central fitting, another fitting is housed, also pierced for its entire length which, in its central part, has two fins or projections, having fitted on its back, a rubber cap or plug.
