Abstract
The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The retainer is provided with outwardly extending lugs for engaging the threaded locking collar of a male luer lock whereby the male luer lock will be held in positive mechanical locking engagement with the coupling site. The valve element is provided with rib members extending inwardly from an inner wall of the valve element toward a slit formed in a diaphragm such that the rib members act to bias the slit to a closed position.
Claims22
A medical coupling site comprising:
- a base;
- a retainer engaged with said base;
- a valve element supported in contact with said base and retained in position on said base by said retainer;
- and
- a lug supported on and extending radially outwardly from said retainer for threadably engaging threads on an internally threaded locking collar to hold said locking collar in engagement with said coupling site.
A medical coupling site for use with a male luer lock having a male luer taper and a threaded locking collar, said medical coupling site comprising:
- a valve element including a substantially tubular body portion having first and second ends;
- a diaphragm extending across said first end of said body portion;
- a retainer surrounding said valve element;
- lug means extending radially outwardly from said retainer for threadably engaging threads on said threaded locking collar;
- and
- wherein said valve element includes an outer wall in contact with said retainer and an inner wall defining a passage for receiving said male luer taper.
A medical coupling site for use with a male luer lock having a male luer taper and a threaded locking collar, said medical coupling site comprising:
- a support base;
- a retainer supported on said base;
- a valve element located within said retainer, said valve element including a substantially tubular body portion having first and second ends and a diaphragm extending across said first end of said body portion;
- lug means extending radially outwardly from said retainer for engaging threads on said threaded locking collar;
- and
- wherein said valve element includes an outer wall in contact with said retainer and an inner wall defining a passage for receiving said male luer taper.
A medical coupling site for cooperation with a medical fitting having a tubular cannula surrounded by an internally threaded collar, said medical coupling site comprising:
- a support base defining a longitudinal axis;
- a retainer supported by said support housing and extending substantially parallel to said longitudinal axis;
- a valve member including a tubular body portion extending substantially parallel to said longitudinal axis and having first and second ends and a diaphragm extending across said first end of said body portion;
- lug means extending radially outwardly from said retainer for engaging threads on said medical fitting;
- and
- wherein a thickness of said body portion, measured in a direction perpendicular to said longitudinal axis, is greater than a thickness of said retainer at a location adjacent to said lug means.
