Patent ID: 8353895

Claim:
A closed system medical connector for use and engagement with a non-luer tip catheter tip syringe, said non-luer tip catheter tip syringe having a tapered distal tip having a total length exceeding 0.300 inches, said closed system medical connector comprising: an upper entrance port, the upper entrance port having both a vertical length greater than 0.300 inches and an entrance opening, a lower fluid communication path, and a valve positioned between the lower fluid communication path and the upper entrance port, said upper entrance port configured and dimensioned as to both said vertical length greater than 0.300 inches and said entrance opening so that said upper entrance port accepts and engages the tapered distal tip of said non-luer tip catheter tip syringe so that said tapered distal tip opens said valve to permit syringe tip fluid flow or fluid aspiration sampling from or back into the non-luer tip catheter tip syringe from said lower fluid communication path, and so that said upper entrance port prevents accepting of or engagement with smaller bore and shorter length uniform standardized dimensioned tapered tips of luer tip or luer lock syringes as defined by ISO/ANSI 1986 standards by preventing said smaller bore and shorter length uniform standardized dimensioned tapered tips of said luer tip or luer lock syringes from reaching beyond said vertical length greater than 0.300 inches of said upper entrance port and thereby preventing contact with said valve to prevent said closed system medical connector from being used as an I.V. administration device by said luer tip or luer lock syringes.
