A self-sealing male Luer connector for connecting to a female Luer connector configured with a tubular barrel of a predetermined interior cross-section, the male Luer connector comprising:
a housing having a central distally-projecting tubular male body and an outer cuff interconnected with the male body along a proximal housing wall so as to form a distally-opening cavity for receipt of the tubular barrel, the male body being formed with an exterior cross-section configured to sealingly engage the interior cross-section of the tubular barrel and an interior lengthwise flow passage terminating distally in a central flow passage opening, the transition between the flow passage and the central flow passage opening defining a nesting surface, the housing wall being formed with at least one activation opening;
a valve means slidably received within the housing for selectively sealing the flow passage; and
a spring means for securing the valve means in place within the housing and effectively biasing the valve means distally within the male body to seal the flow passage, the spring means being responsive to receipt of the tubular barrel within the cavity to allow the valve means to shift proximally to open the flow passage and allow fluid flow through the male Luer connector. |
