1. A multiple lumen access device for medical uses comprising:

  • an infusion introducer having an access tube with a proximal end and a distal end for introduction into the body, the introducer including a hub connected to the proximal end of the access tube and a hemostasis valve in a fixed location within the hub that provides a seal around medical implements that are introduced and withdrawn to and from the body through an access tube lumen, the introducer further including a side arm opening distally with respect to the hemostasis valve for infusing a medical solution to the access tube lumen;

    a catheter including a catheter tube and a junction housing on a proximal end of the catheter tube, the junction housing having a proximal end and a distal end and including a main channel and at least one auxiliary channel separate from the main channel, both the main channel and the auxiliary channel being in fluid communication with at least one lumen defined in the catheter tube; and

    a multi-function adapter having a first unit and a complementary second unit for coupling the catheter to the hub of the infusion introducer such that the catheter tube passes through the hemostasis valve into the access tube lumen, the first unit being attached to the junction housing, and the second unit being fixedly attached to the hub, wherein the first unit may be removably connected to the second unit such that the introducer is converted from an infusion introducer to a multiple lumen access device by virtue of the main channel and the auxiliary channel in the junction housing.
