Abstract

Disclosed is a first medical connector configured to be removably attachable with a second medical connector to permit fluid flow between the first and second medical connectors. The first medical connector can include a first region with a luer-compatible connection portion being configured to engage luer-compatible medical devices, and a second region comprising a resilient seal and a first luer-incompatible connection portion. The first luer-incompatible connection portion can inhibit engagement with luer-compatible medical devices and permit engagement with a second luer-incompatible connection portion of the second medical connector. In some embodiments, the first region of the first medical connector does not rotate with respect to the second region of the first medical connector in an initial stage of use, but the first medical connector is configured to transition from the initial stage of use to a subsequent stage of use in which the first region of the first medical connector and the second region of the first medical connector can be rotated with respect to each other.

Dependent claims

A first medical connector configured to be removably attachable with a second medical connector to permit fluid flow between the first and second medical connectors, the first medical connector comprising:

a first region comprising a luer-compatible connection portion being configured to engage luer-compatible medical devices;
a second region comprising a projection with a first internal conduit, a resilient seal positioned inside of the first internal conduit, and a first luer-incompatible connection portion, the first luer-incompatible connection portion being configured to inhibit engagement with luer-compatible medical devices and configured to permit engagement with a second luer-incompatible connection portion of the second medical connector;
and
a first engagement structure comprising a movable hook configured to engage with a second engagement structure of the second medical connector to removably connect the first medical connector with the second medical connector;
wherein when the second region of the first medical connector is advanced into the second medical connector, a second fluid conduit in a second region of the second medical connector is configured to compress the resilient seal within the first internal conduit of the projection of the first medical connector, such that the resilient seal of the second region of the first medical connector is configured to seal around the second fluid conduit of the second medical connector, and the resilient seal of the second region of the first medical connector is configured to contact a compressible seal of the second medical connector;
and
wherein the first region of the first medical connector does not rotate with respect to the second region of the first medical connector in an initial stage of use;
and wherein the first medical connector is configured to transition from the initial stage of use to a subsequent stage of use in which the first region of the first medical connector and the second region of the first medical connector can be rotated with respect to each other.

A first medical connector that is removably attachable to a corresponding second medical connector, the first medical connector comprising:

a first region comprising an opening, the first region being luer-compatible;
a second region comprising a first resilient seal in the shape of a sleeve positioned inside of a first internal fluid conduit of a luer-incompatible tubular protrusion that is configured to inhibit engagement with luer-compatible medical devices and that is configured to permit engagement with a luer-incompatible opening in the second medical connector;
and
an engagement structure comprising at least one hook configured to removably connect the first medical connector with the second medical connector;
wherein when the second region of the first medical connector is advanced into the second medical connector, the second region of the first medical connector is configured to compress a second seal within the second medical connector and is configured to receive a second internal fluid conduit of the second medical connector within the second region of the first medical connector such that the first resilient seal of the second region of the first medical connector is configured to seal around the second internal fluid conduit of the second medical connector, and the first resilient seal of the second region of the first medical connector is configured to contact the second seal of the second medical connector in an open position;
and
wherein the first region of the first medical connector does not rotate with respect to the second region of the first medical connector in an initial stage of use;
and wherein the first medical connector is configured to transition from the initial stage of use to a subsequent stage of use in which the first region of the first medical connector and the second region of the first medical connector can be rotated with respect to each other.
