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.

Abstract: 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.

Abstract: An IV blood set foot pump includes a base plate, a squeezing plate movably coupled to the base plate by a pivot member and a biasing member coupled to the base plate and the squeezing plate. The biasing member is configured to exert a biasing force against the squeezing plate when the biasing member is in a compressed state. One of the base plate and the squeezing plate comprises a cavity configured to receive an IV pump bulb. IV sets with IV blood set foot pumps and methods of operating IV blood set foot pumps are also provided.
