AV Fistula Needle Set (16G / 17G Twin Pack)

Clinical Engineering & Vascular Protection Features

• Oval Back-Eye Geometry: Precision laser-cut oval back-eye on the arterial needle prevents vacuum suction against the vessel wall (fistula collapse), ensuring steady, uninterrupted arterial blood flow even under negative pre-pump pressures.
• Ultra-Thin Wall Cannula: Maximizes internal lumen diameter without increasing outer puncture diameter, resulting in significantly lower flow turbulence, reduced vein trauma, and lower risk of stenosis or aneurysm formation over prolonged cannulation cycles.
• Flexible Color-Coded Rotating Butterfly Wings: Textured, slip-resistant wings allow technicians to adjust the needle angle during insertion and rotate the bevel 180° after vessel penetration without pulling back, preventing vessel wall gouging. Color-coded per ISO standards (16G Green, 17G Orange, 15G Red).
• Kink-Resistant Medical PVC Tubing: 300 mm ultra-flexible tubing with smooth-operating pinch clamp and precision female luer-lock connector with screw cap ensures secure, leak-proof connection to dialysis blood lines.
• Sterilization & Safety: Ethylene Oxide (EO) gas sterilized, non-pyrogenic, non-toxic, latex-free, and individually blister packaged in sterile pairs (1 Arterial Red Clamp + 1 Venous Blue Clamp).
