1. A medical connector for use in a fluid pathway, the connector comprising:
a housing having a proximal end with a proximal opening and a distal end with a distal male luer opening, a cavity extending therebetween, and configured to be transparent such that the cavity is visible through the housing; a valve member having an interior cavity, said valve member disposed within the housing and configured to be transparent such that the interior cavity is visible through the valve member, and said valve member further having a proximal end that substantially fills the housing proximal opening and includes a proximal opening that is biased closed to obstruct fluid flow therethrough, wherein the valve member is configured to selectively seal the housing proximal opening and to obstruct fluid communication between the housing proximal end and the housing distal end when the valve member is in a first position and to establish fluid communication between the housing proximal end and the housing distal end when the valve member is in a second position; and a support member configured to be received within the valve member, said support member having an inner conduit that extends from adjacent a proximal tip portion having at least one opening that extends through the support member to the inner conduit to a distal end of the support member, and is configured to selectively establish fluid communication between the housing proximal end and the housing distal end, wherein the fluid communication between the housing proximal end and the housing distal end is established when the tip portion and opening protrude through the valve proximal opening and the valve member is provided in the second position and at least a portion of the opening is positioned proximal to the valve member proximal opening, wherein said support member is configured to be transparent such that the inner conduit is visible through the support member; and wherein a fluid flow path establishing the fluid communication between the housing proximal end and the housing distal end is visible through at least a portion of each of the transparent housing, the transparent valve member, and the transparent support member, and wherein the fluid flow path within the inner conduit of the support member from the proximal end of the valve member when the valve member is in the second position to the housing distal end is narrower than the outer diameter of the distal end at the male luer opening.
