A safety I.V. drug introducer set for use with a I.V. administration set is described for facilitating the injection of drugs into a primary fluid line without the necessity of an exposed hypodermic needle. In one embodiment, a Tee is inserted in the I.V. line whose cross-portion includes one or more check valves and whose stem portion comprises a socket for receiving the distal end of an outer tuburlar shaft having a pair of oppositely disposed ports passing through the wall thereof near the distal end. Fitted into the lumen of the outer tubular shaft is an inner tubular shaft having but a single aperture at its distal end alignable with one, the other, or neither of the pair of apertures in the outer shaft. A hollow key member is designed to fit within the non-circular bore of the inner tubular shaft for facilitating the rotation thereof. The key member also includes a single aperture at its distal end which is continuously aligned with the single aperture in the inner tubular member. Moreover, a Luer fitting is provided at the proximal end of the key member whereby a conventional syringe may be joined to it. The kit further includes a needleless spike matable with the key member for transferring a liquid from a medicine vial into a syringe. Alternate embodiments are also disclosed.
