Did you know that the AVF Needle size is critical for effective fistula dialysis? Choosing the right needle ensures both patient comfort and treatment efficiency. In this article, we will explore the different needle sizes used in dialysis and how they impact patient care. You’ll also learn how Topkey Medical’s AVF Needle Assembly Machine ensures precision in needle production.
An AVF Needle (Arteriovenous Fistula Needle) is a crucial tool used in hemodialysis to access a patient’s blood vessels during the dialysis process. It creates a stable connection between the dialysis machine and the bloodstream, enabling efficient filtration and waste removal. These needles are designed to be inserted into the arteriovenous fistula, a surgically created connection between an artery and vein, providing a reliable access point for the dialysis procedure.
● Long-term Dialysis Use: AVF needles are specifically designed for long-term dialysis treatments, offering a secure and effective solution for patients with kidney failure. They are essential in ensuring effective blood flow and patient comfort during the process.
The most common AVF needle sizes used in dialysis are 15G, 16G, and 17G. The choice of needle size depends on factors such as the patient's vein condition, blood flow requirements, and the desired dialysis speed.
● 15G is typically used for patients who require higher blood flow rates.
● 16G is the most commonly used size for adult dialysis.
● 17G is ideal for pediatric patients or those with delicate veins.
● 15G – Ideal for higher blood flow rates (350–450 mL/min), making it suitable for patients with thicker veins needing a higher volume of blood to be processed.
● 16G – Most commonly used for adult patients (250–350 mL/min), offering a balance between adequate blood flow and patient comfort.
● 17G – Best for delicate veins or pediatric patients (200–250 mL/min), ensuring gentle access with minimal discomfort.
Needle Size (Gauge) | Blood Flow Rate (mL/min) | Common Use |
15G | 350–450 | High-efficiency dialysis |
16G | 250–350 | Standard adult use |
17G | 200–250 | Pediatric and fragile veins |
