AV Fastula Needle

AV Fistula Needle – Description

An Arteriovenous (AV) Fistula Needle is a sterile, single-use vascular access device used in hemodialysis to connect a patient’s bloodstream (via an AV fistula or graft) to the extracorporeal blood circuit (blood tubing set and dialyzer).

It enables safe, reliable, and repeated puncture of the patient’s AV fistula for efficient blood flow during dialysis treatment.

Structure and Components

A standard AV fistula needle assembly consists of the following parts:

1. Needle (Cannula):

   • Made of stainless steel, finely polished with a siliconized surface to reduce friction during insertion.

   • Features a beveled tip designed for smooth vessel entry and minimal trauma.

   • Gauge sizes usually range from 15G to 17G, depending on patient blood flow requirements.

2. Hub:

   • Color-coded according to needle gauge for easy identification.

   • Connects the needle to the blood tubing set.

   • May include a rotating or fixed wing mechanism.

3. Wings (Grip):

   • Flexible, ergonomic plastic wings allow for stable handling and secure fixation on the patient’s skin.

   • Designed for comfortable taping and anchoring during dialysis.

4. Safety Shield / Protector:

   • Some models include a safety mechanism (sliding or automatic shield) to cover the needle after use, minimizing needlestick injury risk.

5. Flexible Tubing:

   • Short length of medical-grade, kink-resistant PVC tubing connects the needle hub to the arterial or venous blood line.

   • May have an injection port for saline or medication administration.

6. Cap and Protector:

   • A sterile cap protects the needle before use.

   • Each needle is individually packed in sterile, EO-sterilized packaging.
