    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 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: Pump assemblies for use with an IV set are described herein. A pump assembly includes a rotatable crank, a piston rod, and a diaphragm assembly. The crank includes a crank profile defining a plurality of lobes. The piston rod includes a first follower and a second follower spaced apart from the first follower. The rotation of the crank relative to the piston rod causes the piston rod to reciprocate relative to the crank. The diaphragm assembly includes a housing and a diaphragm member. The diaphragm member is coupled to the housing and cooperatively defines a volume in fluid communication with the IV set. The diaphragm member is movable between an extended position configured to draw in fluid from the IV set and a contracted position configured to expel fluid into the IV set. The diaphragm member is coupled to the piston rod to reciprocate the diaphragm member.

    Abstract: A flow restriction device may include a housing and an insert body. The housing defines a first lumen, a second lumen, and a cavity disposed between the first lumen and the second lumen. The insert body can be disposed within the cavity. The insert body includes a first end, a second end, a longitudinal axis extending through the first and second ends, an outer surface, and a channel. The channel is defined on the outer surface. The channel extends between the first and second ends. The channel includes a first portion that extends in a first direction away from the longitudinal axis and a second portion that extends in a second direction toward the longitudinal axis. The channel and an inner surface of the cavity define a fluid passage in fluid communication with the first lumen and the second lumen.

    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 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 fluid connector assemblies may further include a coupling mechanism for providing a connection between the connectors and maintain a connection that provides a threshold retention force. When an external force greater than the threshold force is applied to the fluid connector assembly, the connectors may be decoupled while the coupling mechanism may remain intact.
