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.

Abstract: A fluid connector device for a blood collection system is disclosed. In order to be safely used with different gauges, the fluid connector device can regulate blood flow therethrough based upon the catheter gauge. For example, when 18-to-22-gauge catheters are used, the fluid connector device regulates the blood flow by positioning a slider assembly (within the fluid connector device) to a setting that allows a single channel to transmit blood through the fluid connector device into a fluid inlet and out of a fluid outlet of the fluid connector device. Alternatively, in another example, when 24-gauge (or greater) catheters are used, the slider assembly can be actuated to a new position, which allows multiple channels to transmit blood into the fluid inlet and out of the fluid outlet. By regulating blood flow, the fluid connector device can limit or prevent hemolysis, while being universally used with different catheters.

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 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 pressure detection system includes a body having an internal chamber with input and output ports and a flexible membrane fluidically sealed to an exposed opening of the chamber to prevent a fluid passing through the chamber from passing through the exposed opening. The membrane is configured to change shape responsive to an increase in pressure caused by the fluid within the chamber satisfying a predetermined threshold. In some implementations, the membrane includes or is part of an identification mechanism which moves outwards, away from the chamber, as the pressure increases to indicate the pressure increase. In some implementations, the identification mechanism includes markings on the surface of the membrane, and an image sensing device reads the markings, and provides an indication of a current pressure associated with the fluid in the chamber based on a variation in the markings from a default state.
