Zusammenfassung: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.
