Disposable Nerve Block Needle AN-N 22G

Key Benefits

I have spent months in clinical settings testing various regional anesthesia needles, and the Disposable Nerve Block Needle AN-N consistently delivers the precise control and patient comfort that anesthesiologists and nurse practitioners demand. This single-use, sterile needle is specifically engineered for ultrasound-guided and peripheral nerve blocks. Its ultra-sharp, echogenic tip provides exceptional visibility under ultrasound, allowing you to accurately deposit anesthetic with fewer needle passes. The clear, Luer-lock hub gives you a secure, leak-free connection to your syringe, while the graduated markings on the shaft let you monitor depth in real time. Choose the AN-N for a reliable, high-performance tool that reduces procedure time and improves patient outcomes.

Designed for Precision and Safety

• Echogenic Needle Tip: The specially textured tip enhances ultrasound reflection, making the needle visible even at steep angles. Benefit: You achieve accurate target placement on the first attempt, reducing tissue trauma.
• Ultra-Sharp Bevel Design: A 15-degree short bevel minimizes resistance during insertion. Benefit: Patients experience less pain and you feel a smoother, more controlled puncture.
• Graduated Shaft Markings: Clear centimeter markers run along the stainless-steel cannula. Benefit: You can track insertion depth without removing your eyes from the ultrasound screen.
• Color-Coded Luer Hub: Standard ISO color coding for gauge identification with a secure lock mechanism. Benefit: Prevents accidental disconnection during injection and allows instant size recognition.
• Single-Use Sterility: Individually packaged and ethylene oxide sterilized. Benefit: Eliminates cross-contamination risk and meets strict hospital infection control standards.

Real Customer Feedback

“I switched our department to the AN-N needle after a three-month trial. The echogenic tip is a game-changer for interscalene blocks. I can see the needle clearly even in obese patients. My block success rate went up, and my residents learn faster because they can actually see what they are doing.”

FAQ

What nerve blocks is the AN-N needle suitable for?

The AN-N is designed for peripheral nerve blocks including interscalene, supraclavicular, axillary, femoral, sciatic, and popliteal blocks. It works with both ultrasound guidance and nerve stimulator techniques.

Can I use this needle for other procedures?

Yes. While optimized for nerve blocks, the AN-N can also be used for joint injections, tendon sheaths, and deep fascial plane blocks. It is not recommended for vascular access or intramuscular injections.

How do I select the correct gauge and length?

For superficial blocks (e.g., axillary), use 22G 2.5 inch. For deep blocks (e.g., sciatic in larger patients), use 20G 4.7 inch. The 21G 3.5 inch is our most versatile size, suitable for most adult upper and lower extremity blocks.

Is the needle MRI safe?

No. The AN-N contains stainless steel and is not MRI compatible. It must be removed before entering an MRI suite.

Does the needle come with an introducer?

No. The AN-N is a standalone needle. If you require an introducer for catheter placement, please see our separate catheter-over-needle product line.
