1. A closed connection system having a connector and a non-luer tip catheter tip syringe, said syringe having a tapered distal tip with an initial outside diameter larger than 0.165 inches and an internal diameter larger than 0.090 inches with a total length exceeding 0.300 inches providing for either fluid infusion or fluid sampling through said connector, said connector including a lower fluid path, an upper entrance port, and a valve positioned between the lower fluid path and the upper entrance port, the valve having a diaphragm with a slit opening normally biased to a first sealed closed position thereby preventing fluid from exiting the lower fluid path and out the slit opening in the valve, the valve openable to a second open position by the manual insertion of the syringe tapered distal tip into engagement with the upper entrance port to progressively contact, downwardly bend, transverse through and maintain contact with the sides of the slit opening in the valve so as to thus hold open the valve, the upper entrance port including walls defining an entrance opening, said walls downwardly inwardly tapered between 3 and 5 degrees forming a wedge lock disengagement resistant fit with the downwardly inwardly tapered distal tip of the syringe, such fit preventing disengagement of the syringe tapered distal tip with the upper entrance port opening caused by fluid back pressure during use of the syringe.
