An interface device is described which includes a body defining one or more cylindrical bores which are dimensioned to receive a standard luer lock syringe. Each bore includes a plunger movably positioned therein from a retracted position to an advanced position. The plunger and the distal end of the bore defines a first fluid reservoir and the standard syringe assembly defines a second fluid reservoir. The interface device and the syringe assembly are operable to sequentially deliver multiple fluids from the interface device to a catheter assembly.
