<p>The present invention is an improved stopcock for safely administering dangerous medicaments that are injected into a patient's body. The stopcock comprises: A fluid guiding device comprising an outer body provided with four openings and an inner body provided with a first conduit, from which an additional conduit branches. The first conduit lies essentially along the diameter of the outer body, wherein the openings provided in the outer body correspond to the ends of the first and the additional conduits. The chord between the ends of the first and the additional conduits is essentially equal to the chord between two corresponding openings of the outer body. One opening has an axis that makes an angle of about 90 degrees with the axes of each of the two openings adjacent to it. The stopcock also comprises two inlet/outlet ports that are independently connected to the first and second openings of the outer body and a spike or a vial holding member that is independently connected to the third and fourth openings of the outer body.</p> |
