Claim 8:
9. An injection port assembly, comprising:
a body including a first mating structure and a second mating structure configured to be coupled to the first mating structure, the body having a central body axis extending from a distal body end defined on the first mating structure to a proximal body end defined on the second mating structure;
the first mating structure including:
an outer wall defining an open proximal end of the first mating structure facing toward the proximal body end;
an inner cylindrical surface extending distally from the open proximal end of the first mating structure, the inner cylindrical surface having a first inner diameter;
a male luer connection connected to the outer wall and extending distally to a free end, the male luer connection including an axial passage, the axial passage having a second inner diameter smaller than the first inner diameter;
a base integrally formed with the outer wall and spanning the body axis and supported from the outer wall, the base being located axially between the open proximal end of the first mating structure and the axial passage of the male luer connection, the base having a base outside diameter substantially equal to the second inside diameter of the axial passage of the male luer connection; and
a plurality of transverse passages partially frusto-conical in shape tapering from the first inner diameter of the inner cylindrical surface to the second inner diameter of the axial passage of the male luer connection to bypass the base and communicate the inner cylindrical surface with the axial passage of the male luer connection;

the second mating structure including a female luer connection configured to receive a male luer fitting, the second mating structure having an interior communicating the female luer connection with the open proximal end of the first mating structure; and
a flexible valve member having a proximal valve end portion configured to be sealingly received in the female luer connection of the second mating structure when the flexible valve member is in a closed position, the flexible valve member being configured to be displaced relative to the central body axis upon entry of the male luer fitting into the female luer connection to thereby place the male luer fitting in communication with the interior of the second mating structure, the flexible valve member including a distal end mounted on the base of the first mating structure such that the distal end of the flexible valve member is entirely supported by the base.
