Abstract: Fluid connector assemblies that seal off fluid paths in the respective connectors are disclosed. When connectors of a fluid connector assembly are connected to each other, respective compressible members in the connectors are displaced, allowing downstream fluid passage through the fluid connector assembly. The connectors maintain a connection by a snap mechanism that provides a threshold retention force. When an external force greater than the threshold force is applied to the fluid connector assembly, the snap mechanism may no longer maintain the connectors together, causing the connectors to decouple from each other. However, each of the compressible members can return to their respective original positions and shapes to seal off respective fluid paths in the connectors, thus preventing further downstream and upstream flow through the fluid connector assembly and limiting or preventing fluid loss.

Abstract: Fluid connector systems including first and second connector portions couplable together to form a fluid pathway therethrough and can resist separation or permit separation as desired. A connector portion can include a connector housing and a cover portion. The connector housing includes a connector body and an engagement portion. The connector body defines a tubing opening and a mating opening. The connector body defines a flow path between the tubing opening and the mating opening. The engagement portion at least partially surrounds the connector body. The engagement portion defines an engagement lip extending radially toward the connector body and is configured to releasably engage the connector housing. The flow path includes at least one portion that is normal to the engagement portion. Fluid flow through the flow path exerts a normal force on the connector housing and prevent release of the connector housing with the mating connector portion.

Abstract: Fluid connector systems including first and second connector portions couplable together to form a fluid pathway therethrough and can selectively resist or permit separation as desired. A connector portion can include a connector housing and a cover portion. The connector housing includes a connector body and an engagement portion. The connector body defines a housing volume, a luer opening and a mating opening. The housing volume is in fluid communication with the luer opening and the mating opening. The engagement portion may include an engagement lip extending radially toward the connector body. The engagement lip is configured to releasably engage the connector housing with a mating connector portion. The cover portion is configured to selectively surround the engagement portion of the connector housing. The cover portion is slidable to engage with the engagement portion of the connector housing and prevent release of the connector housing with the mating connector portion.

Abstract: Fluid connectors assemblies that provide neutral fluid displacement without overlapping connectors are disclosed. A fluid connector assembly may include a housing and a pair of connectors (e.g., luers) coupled with the housing. A compressible member is located within the housing. The first connector and the second connector each include a post with an opening. The compressible member can seal off the opening of the first connector from fluid entry. However, when the post of the second connector is inserted into the housing, the post of the second connector displaces the compressible member, causing the compressible member to create a fluid path, thereby allowing fluid to flow through the internal volume of the housing. Further, the compressible member seals the housing until each of the first connector and the second connector are coupled therewith forming a fluid path through the posts.

Abstract: A connector for connecting a container containing a medical fluid to a vascular access device may include an upper housing defining a first internal chamber, and a lower housing coupled to the upper housing and defining a second internal chamber for circulation of the medical fluid into the outlet. The connector may further include a slider disposed at least partially in the first and second internal chambers, and a plug coupled to a distal end of the slider. The slider may be reciprocally movable between (i) an open position, where the plug is spaced apart from a floor of the internal chamber to allow the medical fluid to flow through the outlet, and (ii) a closed position where the plug abuts the floor of the second internal chamber to block the medical fluid from flowing through the outlet.

Abstract: A flow restriction device includes a proximal housing configured to couple to a fluid collection device, a distal housing configured to couple to a catheter assembly, an intermediate housing interposed between the proximal and distal housings, an internal fluid channel extending transversely through the proximal, intermediate and distal housings, and a fluid shield device coupled to the distal housing, the fluid shield device comprising a flexible material. The fluid shield device covers an end portion of a male center post of the distal housing in an unconnected position, compresses down the male center post into a groove of the distal housing in a connected position, and recovers the end portion of the male center post to contain fluid within the male center post upon returning to an unconnected position. Blood collection systems and fluid shield devices are also provided.

Abstract: Fluid connectors assemblies that provide neutral fluid displacement without overlapping connectors are disclosed. A fluid connector assembly may include a housing and a pair of connectors (e.g., luers) coupled with the housing. A compressible member (e.g., bellow) is located within the housing. The first connector and the second connector each include a post with an opening. The compressible member can seal off the opening of the first connector from fluid entry. However, when the post of the second connector is inserted into the housing, the post of the second connector displaces the compressible member, causing the compressible member to uncover the opening, and further causes the compressible member to open in another location and receive fluid. Further, the compressible member seals each of the first connector and the second connector and forms a fluid path through the posts and the compressible member, with the seals regulating fluid flow.
