Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Used on central venous catheters, PICCs, ports, drains, and other access devices that require repeated connection while maintaining a closed system.
What most clearly distinguishes it from similar devices?
Key distinctions
This is a hub-access accessory that creates a closed needleless connection for injection, aspiration, or flushing; it does not secure the catheter to skin or close the insertion site.
