How to Use ChemoBloc Vial Venting Pin and Syringe Kit Safely

Quick answer

Use the ChemoBloc / ChemoPlus Vial Venting Pin and Luer-Lock Syringe Kit to safely withdraw medication from a vial while minimizing exposure to hazardous drugs.

Step-by-step safety procedure

1. Prepare your workspace and kit: Clean your work surface and put on appropriate personal protective equipment (PPE). Remove the ChemoBloc / ChemoPlus kit from its packaging. Inspect the vial-access pin and Luer-lock syringe for damage. Do not use if the sterile seal is broken. Common mistake: Skipping the inspection of the sterile seal can lead to contamination.
2. Attach the vial-access pin to the vial: Hold the medication vial upright. Pierce the stopper with the filtered vial-access pin using a straight, steady motion. Push until the pin is fully seated. The built-in filter will allow air to escape when you later withdraw liquid, maintaining pressure balance. Checkpoint: Ensure the pin is fully inserted to prevent air leaks during withdrawal.
3. Connect the Luer-lock syringe: Align the Luer-lock syringe with the pin's connector. Twist clockwise until you feel a firm stop. Do not force it. The Luer-lock design creates a secure, leak-resistant connection. Common mistake: Over-tightening can crack the connector; stop as soon as you feel resistance.
4. Withdraw the medication: Turn the vial upside down so the fluid covers the pin tip. Slowly pull back the syringe plunger to draw the desired volume. The filter vents air into the vial, preventing vacuum buildup. Avoid rapid withdrawal, which can create froth. Checkpoint: If you see air bubbles in the syringe, tap the barrel and push a small amount back to clear them.
5. Disconnect and dispose safely: Once the correct volume is drawn, twist the syringe counterclockwise to disconnect it from the pin. Keep the pin attached to the vial stopper for disposal. Dispose of both the pin and syringe as hazardous waste according to your facility's protocol. Common mistake: Leaving the pin on the vial after use risks accidental needle-stick; always dispose of the assembly together.
