There is provided a catheter having a hub portion in which a rotatable intravenous receiving member is mounted. In one position the rotatable member provides a passageway for a needle passable through the rotating portion and the hub end and extending portion of the catheter. After insertion of the catheter into the patient, the needle is withdrawn from the assembly. Before inserting the needle into the patient and then withdrawing the needle from the assembly, an end of an intravenous conductor is connected to the receiving socket in the rotating portion and placed in a fluid-flow condition or the intravenous connector can be inserted after venipuncture. After the needle is withdrawn, the rotatable portion is turned to bring the connected fluid source into flow condition to and with the catheter. A filter may be provided in the passageway of the fluid conduit in the rotatable portion.
