Medical intravenous administration connectors according to a first embodiment include a first coupling member having a female luer, a valve member having a substantially rigid stem and a substantially resilient body with a sealing surface, and a second coupling member having a fluid coupling extending from one end and an internal valve member support. The coupling members are structured to couple to each other with the valve member being biased to a closed position. When assembled, the valve stem extends into the female luer, and the valve body biases the sealing surface against an annular ring in the first coupling member thereby blocking fluid communication. Vanes are provided in the second coupling member on which the resilient body of the valve sits, with the vanes acting as a centering mechanism for the valve. The valve is opened for fluid flow through the assembly by coupling a male luer to the female luer of the assembly. According to a second embodiment, the valve stem is replaced by a dome-like protrusion on the resilient valve body. The valve of the second embodiment is opened by applying fluid under pressure through the female luer. According to a third embodiment, the valve is partially rigid and partially resilient. All embodiments are easy to prime, limit priming volume, and are arranged without dead-spaces in which blood can be trapped.

[ I claim:] [1.] A fluid line connection assembly for coupling to and uncoupling from a first fluid pathway which terminates in a first male luer, the fluid line connection assembly comprising:a) a first coupling member having a first female luer at a first end of said first coupling member, and a first mating structure;b) a valve member having a stem and a resilient body with a sealing surface, said valve member disposed relative to said first coupling member with said stem extending into said first female luer, said stem having a pair of spaced apart upstanding members and a pair of inclined surfaces meeting at a peak between said upstanding members, said inclined surfaces being arranged to direct fluid flow radially outward from between said upstanding members; andc) a second coupling member having an open generally cylindrical chamber with a valve member support, a first fluid coupling member in fluid communication with said cylindrical chamber, a valve member support, and a second mating structure for mating and coupling with said first mating structure, said second coupling member being coupled to said first coupling member with said valve member support supporting said resilient body of said valve member such that said sealing surface is biased against said first female luer thereby blocking fluid communication between said female luer and said first cylindrical chamber.
