Abstract: Connector assemblies are disclosed. A connector assembly includes a housing with a post and a valve surrounds the post. The valve is displaceable and based upon the displacement allows fluid to pass therethrough. While providing fluid, a fluid delivery device provides an external force to displace the valve, causing the valve to form a fluid pocket that receives fluid from the fluid delivery device. As the fluid delivery device is removed from the connector assembly, the fluid pocket collapses and drives fluid stored in the fluid pocket through an opening in the post, where the fluid flows downstream to a catheter line. Additionally, the valve closes and covers the post prior to removal of the fluid delivery device. The collapsing fluid pocket and the valve closing prevent the fluid previously in the fluid pocket from upstream fluid flow otherwise caused by removal of the fluid delivery device.

The plurality of first retaining fingers may be radially biased inward toward the cavity and configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler.

Abstract: A connector includes an outer housing defining a lumen, a first male coupler mateable with a needle-free valve and positioned at a first end of the outer housing, a second male coupler positioned at a second end of the outer housing, a valve system to control fluid flow through the lumen, and an actuator movable within the outer housing between a first position and a second position. A pinch clamp of the connector operates to selectively deflect locking fingers of the actuator from a locked position to a movement position to selectively enable or prevent movement of the actuator from the first position to the second position. The actuator, based on its positioning in the first or second position, causes the valve system to be in a closed state or an open state and blocks or allows the first coupler to couple with the needle-free valve.

Abstract: A needleless connector may include a housing having an inlet port, an outlet port, and an inner surface defining an internal cavity extending between the inlet and outlet ports, and a compressible valve reciprocally disposed within the internal cavity.

In an open state, where the compressible valve is subject to an axial force, the top section of the head portion may be lodged between two pinch points between opposing walls of an inwardly angled portion of the internal surface. Additionally, in the open state, the top section of the head portion may have a non-planar shape defining a fluid path extending at least partially between opposing walls on an outwardly angled portion of the internal surface.

Abstract: Check valve are disclosed having a primary seal and a secondary seal, where the primary and secondary seals resist movement of a fluid through the check valve, and the secondary seal can provide a backup seal in an instance where the check valve does not function as intended.

The valve body is configured to move relative to the first and second sealing ridges, and can have a position wherein a portion of the valve body is engaged against any of the first and second sealing ridges.

Abstract: A Luer coupling limits the maximum assembly torque applied to corresponding male and female Luer connector portions of the coupling and another vascular access device (VAD). Corresponding, opposing detents, which are in slidable, mating, abutting engagement contact with each other, limit the maximum applied torque during Luer assembly by slipping past each other when exceeding a desired torque threshold. The torque threshold is selected to be sufficiently high to assure fluid-tight connection, but below a level that induces seizure of the mating Luer connector components. In some embodiments, the opposing detents also create audible and/or tactile vibrations, such as a “clicking” sound as the opposing detents skip over each other. In some embodiments the opposing detents are a pawl and a ratchet.
