Fistula Needles

1. Sharp and smooth bevel design – Ensures clean, one‑stick penetration with minimal trauma to the vessel wall, reducing patient discomfort. 2. Color‑coded wings / connectors – Typically red for arterial (outflow) and blue for venous (inflow) lines, allowing easy identification and reducing the risk of misconnection. 3. Rotating or non‑rotating safety wings – Provides secure grip and control during cannulation; some models feature safety shields to prevent needle‑stick injuries after use. 4. Flexible, kink‑resistant tubing – Made of medical‑grade PVC or polyurethane, maintaining consistent blood flow during dialysis without collapse or torsion. 5. Radiopaque marker / echogenic tip (optional) – Enhances visibility under imaging guidance, helpful for difficult access or ultrasound‑guided cannulation.
