A dual lumen IV administration set includes a first lumen having an inner diameter of a first value. A second lumen is paired with the first lumen, and the second lumen has an inner diameter of a second value that is greater than the first value. A flow merger merges flow output from a distal end of the first lumen and flow output from a distal end of the second lumen to form a single flow output in an exit lumen. An injection port intersects the first lumen, thereby providing injection access to flow therethrough, prior to merging with the flow output of the second lumen.

A modular connector assembly for a medical container may include a plurality of covers and a plurality of adapters. Each cover is connectable to a cooperatively dimensioned medical container. Each adapter is attachable in fluid sealing engagement with each cover by an interface assembly including a first interface segment formed on each of said plurality of covers and a second interface segment formed on each of said plurality of adapters. The first and second interface segments and corresponding ones of the covers and adapters are initially separable and subsequently connected to define a fluid sealing engagement between connected ones of the cover and adapter. The structural configuration of each of the plurality of adapters is variable to define a different one of a plurality of medical connector types.

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 compressible valve within a cavity and configured to surround a post forming a fluid passage, the compressible valve can resist fluid flow through the post in a first position and to reduce the resistance to fluid flow through the post in a second position, 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 coupled together the compressible valve is moved toward the second position and the post extends through the compressible valve and the valve plug to form the fluid pathway through the connector system.

A medical device may include a distal connector, which may include a first lever arm and a second lever arm. A distal end of the first lever arm and a first end of the second lever arm may include a first protrusion and a second protrusion, respectively. The distal connector may include a blunt cannula disposed between the first lever arm and the second lever arm. The medical device may include a cover coupled to the distal connector and having an annular wall surrounding the blunt cannula. The first protrusion and the second protrusion may contact at least one catch disposed on an outer surface of the annular wall. A proximal end of the first lever arm and a proximal end of the second lever arm may be configured to be pinched together to remove the first protrusion and the second protrusion from the at least one catch.

An infusion base for attachment to a user of an infusion set comprises an adapter having a lower portion, an inner wall portion, and a gap between the lower portion and the inner wall portion. At least one of the lower portion and the inner wall portion is configured to receive an attachment.

A needleless connector and methods for preventing microbial ingress in medical device connections are disclosed. Various examples provide a needleless connector including a male luer having a recessed distal tip surface containing a water-soluble antimicrobial composition. Further examples include a trap for retaining antimicrobial composition. As the needleless connector is inserted into a female connector, a tapered surface distal edge acts to push microorganisms, while the distal tip surface is configured to leave microorganisms undisturbed. After insertion of the needleless connector, microorganisms present on the female luer surface are biased to reside in the recess region. The recess, trap, and antimicrobial composition are configured to facilitate a long-lasting supply of antimicrobial solution within the fluid-filled recess, at the same time confining the antimicrobial solution inside the recess. This produces a high concentration of antimicrobial solution for an extended time, killing microbes, stopping microbial ingress, and preventing infections in patients.
