Fistula Needle: Precision Vascular Access for Optimized Hemodialysis
Fistula Needle Clinical Purpose
Engineered for reliable and comfortable vascular access in renal patients, our fistula needles enable high-flow hemodialysis through arteriovenous (AV) fistulas and grafts. The specialized design minimizes recirculation while maximizing blood flow rates essential for efficient toxin clearance.
Die wichtigsten Vorteile
Pain-Reduced Puncture
– Laser-honed 12° bevel tip requires 35% less insertion force vs. standard needles
– Micro-smooth inner lumen with hydrodynamic polishing prevents platelet adhesion
Enhanced Flow Efficiency
– Patented side-hole configuration (3+1 asymmetric design) increases effective flow area by 28%
– Turbulence-reducing geometry maintains laminar flow up to 450 mL/min
Secure Cannulation
– Color-coded wings for rapid gauge identification
– Reverse-barbs secure tubing while allowing smooth needle withdrawal post-treatment
Fortgeschrittene Werkstofftechnik
– Cannula: Medical-grade 316LVM stainless steel (Ra ≤0.2μm surface roughness)
– Hub: Transparent polysulfone with integrated flashback chamber
– Wings: Latex-free TPE with textured grip for secure handling
