Description

The AVF Safety Needle is a specialized medical device meticulously designed for vascular access in hemodialysis patients. Its primary function is to facilitate secure and efficient access to an arteriovenous fistula (AVF), a crucial connection between an artery and a vein, enabling seamless blood withdrawal and return during dialysis treatment.

Key Features

• Advanced Safety Mechanism
  The needle is equipped with an active, nonreversible safety mechanism that locks with an audible and tactile 'click,' significantly reducing the risk of needlestick injuries. This feature enhances safety without requiring any alteration in the puncture technique.

• Precision Needle Design
  The ultra-sharp, siliconized 3-bevel needle ensures smooth cannulation, minimizing vessel trauma. Its ultra-thin wall design optimizes blood flow, and it is available in both straight and curved configurations to suit various patient anatomies and access sites.

• Enhanced Blood Flow
  Certain models feature additional holes or grooves, crafted with 5-axis laser cutting, to improve blood flow and reduce the risk of clotting.

Handling and Identification

• Textured Wings and Clamps
  The needle includes textured, color-coded wings that are either turnable or fixed, providing secure handling and easy identification. A color-coded occlusion clamp further aids in management.

• Flexible Tubing
  Soft, flexible tubing allows for easier clamping and minimizes movement, while a tapered luer connection ensures a secure fit.

Material and Manufacturing Excellence

• High-Quality Materials
  Constructed from medical-grade stainless steel (304 or 316L), the needle offers high corrosion resistance and biocompatibility. It is latex-free and not made with DEHP or BPA, ensuring safety for a wide range of patients.

• Sterility Assurance
  Each needle is sterilized by gamma irradiation and designed for single-use, preventing infection and maintaining functionality.

Available Configurations

The AVF Safety Needle is available in arterial, venous, or combined versions, with options for turnable or fixed wings. It comes in various gauges (14G, 15G, 16G, 17G) and needle lengths (20 mm, 25 mm, 30 mm), with tube lengths of 150 mm or 300 mm.

Manufacturing Standards

Manufactured using advanced processes such as 5-axis laser cutting, electropolishing, and ultrasonic cleaning, the needle meets rigorous quality standards, including ISO 7864, ASTM F3014-14, and ISO 10993. Quality control includes detailed inspections of needle tips and features.

Professional Use

Designed for use by trained healthcare professionals, the AVF Safety Needle requires specific insertion techniques to minimize complications. Proper care involves maintaining sterility and regular inspection, with packaging options that include sleeving and custom configurations to meet diverse needs.
