Claim 2:
3. The multi-port syringe system of claim 2 wherein:
the syringe barrel closed end further comprises a cylindrical boss wherein:
the cylindrical boss is centered on the syringe barrel central axis;
the cylindrical boss comprises the syringe barrel port; and
the cylindrical boss fits into a cylindrical receptacle in the port body cylindrical cavity;

the first port, second port, and third port comprise apertures in the side walls of the cylindrical receptacle;
the syringe barrel further comprises a plunger stopper aperture located in the cylindrical tube proximate to the syringe barrel open end;
the multi-port syringe system further comprises a plunger stopper wherein the plunger stopper comprises a feature configured for:
insertion through the plunger stopper aperture;
prevention of accidental removal of the plunger from the syringe barrel; and
rotationally coupling the plunger with the syringe barrel;

the syringe barrel further comprises a protrusion on the exterior of the cylindrical tube configured for retaining the syringe barrel portion inside the port body cylindrical cavity;
