Abstract
A male luer connector device that attaches to any standard female luer valve to open a flow channel between the two luers. The male luer is comprised of a tubular housing element, a resilient member contained within the housing and extending within an inner tubular portion defined in the housing, a resilient member that extends within the inner tubular portion of the housing, and a valve member attached to the resilient member that seals the tubular portion. When the male luer is engaged with any standard female luer, a female luer connector device drives the resilient member of the male luer into a compressed position to open the forward end of the male luer and permit liquid flow between the luers.
Claims5
A male luer medical fluid connector for engaging a female luer connector to open a flow channel through the male luer connector, the male luer connector comprising:
- a male luer portion having a forward end for engaging a female connector;
- a dual stage valve member located within the male luer portion, the valve member having an open position when the male luer portion is engaged with a female connector at which position fluid can flow through the male luer portion, and a closed position when the male luer portion is disengaged from a female connector at which position fluid is prevented from flowing through the male luer portion;
- and
- a vacuum section that creates a relative vacuum within the forward end of the male luer portion;
- wherein a first valve stage of the dual stage valve member is configured to isolate the vacuum section from upstream liquid before a second valve stage of the dual stage valve member closes.
