Medical connector with closeable luer connector

A luer connector comprising:

• a housing having a hollow bore, a first end, and a second end;
• a male luer tip supported by the housing configured to rotate with respect to the housing, the male luer tip having a first open end and a passageway through the male luer tip in fluid communication with the first open end;
• and
• a substantially rigid internal member extending into the passageway of the male luer tip toward the first open end of the male luer tip;
• wherein:
• at least one of the male luer tip and the internal member is axially moveable between a first position and a second position relative to the other of the male luer tip and the internal member;
• the male luer tip and the internal member cooperate such that rotation of the male luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the male luer tip and an end portion of the internal member;
• in the first position, the end portion of the internal member provides a substantially fluid-tight seal with respect to the first open end of the male luer tip so as to substantially prevent a flow of fluid through the male luer tip;
• and
• in the second position, the end portion of the internal member is spaced apart from the first open end so that fluid is permitted to flow through the first open end of the male luer tip.
