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.

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 coupler including a first connector having a first end, a second end opposite the first end, and a first valve disposed between the first end and the second end. The first valve having a compressed state and an expanded state. The coupler includes a second connector having a housing, a connecting portion extending from the housing, and a second valve disposed at least partially within the housing, the second valve having a compressed state and an expanded state. The coupler further includes a collar coupled to the housing of the second connector and configured to receive at least a portion of the first connector to detachably couple the first connector to the collar and the second connector such that the housing of the second connector is at least partially disposed within the first connector.

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.
