Aspects of the present disclosure provide a fluid connector assembly, comprising a housing, comprising an upper housing including a female luer port, a lower housing including a male luer port and a cannula flow channel passing through the male luer port, and an internal volume fluidly connected to a first end and a second end and an elastomeric valve disposed in the internal volume, the elastomeric valve comprising a cavity, wherein when the male luer port is inserted into the female luer port of the upper housing, the elastomeric valve is configured to be stretched and pushed downwards, allowing a tip of the male luer port to interface with the cannula flow channel and for fluid to flow through the fluid connector assembly.

A luer connector including a rigid housing having a first end and a second end. The housing further including a rigid tubular male portion at the first end, a rigid tubular female portion at the second end, and a longitudinal opening therethrough. The male portion is configured to be engageable with a female connector. The female portion is configured to be engageable with a male connector and to prevent the disengagement of the male connector from the female portion. In some embodiments, the female portion is configured to maintain a fixed rotational position when the male connector is being threaded therewith, but to rotate with the male connector once the male connector has become fully engaged with the female portion so as to prevent the male connector from becoming unthreaded from the female portion.

Fluid connector systems that can include first and second valve assemblies that are couplable together to form a fluid pathway through the fluid connector system when the first and second valve assemblies are coupled together, and can resist fluid flow through each of the first and second valve assemblies when the first and second valve assemblies are separated from each other, where the first and second valve assemblies can include a compressible element or post positioned within a channel and configured resist fluid flow through the respective first or second valve assembly in a first position and to reduce the resistance to fluid flow through the first or second valve assembly in a second position, and the first and second valve assemblies including a sleeve and one or more arm configured to engage each other to form a snap fitting feature that can resist separation therebetween.

A breakaway medical connector can include a housing with engagement features that interface with corresponding engagement features on a breakaway member so that the breakaway is attached to the housing. A second connector can couple to the breakaway member to provide a fluid connection between the first connector and the second connector. If a force above a threshold is applied that pulls the second connector apart from the breakaway connector, the engagement features can be overcome and the breakaway member can detach from the housing. The second connector can detach from the first connector along with the breakaway member. The connector can have a valve that closes the fluid pathway upon the separation of the breakaway member from the housing. In some embodiments, the breakaway member can be reattached to the housing, such as to reestablish fluid communication between the breakaway medical connector and the second medical connector.

Disclosed herein are embodiments of a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway, a male coupler having a second passageway, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system. Further disclosed herein are embodiments of a connector system for releasably connecting together tubes, whereby the connector system includes at least one valve biased by a valve-biasing member disposed external to or outside of the fluid flow path.

Fluid connector systems including first and second valve assemblies couplable together to form a fluid pathway therethrough, and can resist fluid flow through the connector system when the valve assemblies are separated from each other, the first valve assembly including a post forming a fluid passage, and the second valve assembly including a valve plug positioned within a bore and configured to obstruct a fluid passage, such that when the valve assemblies are separated, a slit of the valve plug resist fluid flow therethrough, and when the valve assemblies are coupled together the post extends through the compressible valve and engagement of a ridge of the valve plug against the post resist fluid flow between the post and the ridge.
