Dorsal Hole Needle Tube (Internal Fistula Needle Tube)

• Dialysis-specific Dorsal Hole Needle (Arteriovenous Fistula Needle), used for establishing vascular access for hemodialysis, providing a safe puncture tool for routine dialysis in end-stage renal disease patients
• Back-hole design with clinically optimized angle ensures close adherence to the internal fistula vessel wall after puncture, reducing endothelium friction and lowering the risk of long-term vascular damage during dialysis
• The back-hole design enables bidirectional blood flow, ensuring stable dialysis blood flow rates. This prevents insufficient blood flow from compromising efficiency, thereby facilitating optimal toxin clearance and fluid balance
• Precision grinding of the needle hole edges eliminates burrs, reducing patient discomfort during puncture, preventing vascular damage that causes hematomas, and enhancing dialysis comfort
• Medical-grade biocompatible material with a vented design to reduce blood retention in the cannula, lowering the risk of thrombosis and ensuring dialysis safety
