Abstract:
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, a first mating structure, and a first annular sealing surface;b) a valve member having a substantially resilient body with a centrally located surface protrusion defining a second annular sealing surface, said valve member being dimensioned such that it is not activated by a male luer inserted into said first female luer; 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, 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 second sealing surface is biased against said first annular sealing surface thereby blocking fluid communication between said female luer and said first cylindrical chamber, whereinwhen a fluid under pressure is introduced through said first female luer, said substantially resilient body is axially compressed by the fluid moving said second annular sealing surface away from said first annular sealing surface allowing the fluid to pass from said first female luer to said first fluid coupling member.
