Luer Valve Technology — Needle-Free Access

The Fleboflex Luer injection/extraction port uses a Luer-lock valve with automatic locking for safe, quick, and repeatable access to the interior of the bag. Understanding this mechanism is critical to proper technique and maintaining sterility during compounding.

How it works: Connect a standard Luer-lock syringe to the valve by inserting and giving a small rotational twist to engage the auto-lock. The connection is secure — no dripping occurs at connection or disconnection. Once locked, push or pull the syringe plunger to add or withdraw solution. When finished, reverse the rotational twist to disconnect cleanly.

The valve seals automatically upon disconnection, preventing any fluid leakage or environmental contamination between accesses. This is a fundamental advantage over traditional rubber-septum ports, which can core (create particulate fragments) after repeated needle punctures and lose seal integrity over time.

For vial reconstitution, Fleboflex Luer is compatible with standard male vial adaptors. The workflow is: (1) place the vial adaptor onto the medication vial using the blister technique (press adaptor awl through vial stopper without removing the blister, then remove the blister), (2) connect the vial-plus-adaptor assembly to the Luer valve on the bag, and (3) reconstitute by transferring solution between bag and vial as needed.

The Luer valve is also compatible with Closed System Transfer Devices (CSTDs) that use a Luer interface, making Fleboflex Luer suitable for hazardous drug compounding workflows where closed-system containment is required.
