Medical Grade Stainless Steel Back Cut Notched Needle Tube For IV Catheters ISO9626 SUS304

Medical Back-Cut Notched IV Needle Tube adopts high-purity medical-grade SUS304 stainless steel as the raw material, processed through precision cold drawing, precision grinding, back-cut bevel forming and notch machining. Designed specifically for intravenous (IV) infusion, hypodermic injection and minimally invasive medical procedures, this specialized needle tube integrates back-cut sharp bevel and precise notch positioning structures. It features high biocompatibility, smooth piercing performance and stable structural consistency, and is the core tubular component for disposable and reusable medical injection and infusion needle devices. YUHONG GROUP has produced medical grade stainless steel needle tubes for more than 30 years, especially from 10G to 34G diameter sizes. Our factory has several production lines and stable product quality. We can make customized stainless steel needle tubes based on clients' drawings and samples.

The Advantages Of Back-cut Notched Needle Tubes:

• The Back-Cut (Reverse Bevel) Design: The back-cut feature positions the primary cutting edge on the internal curvature of the needle tip. This "reverse" geometry ensures that the sharpest cutting edge interacts with the tissue during the final stage of venipuncture, significantly reducing the tissue plugging. It creates a smoother entry trajectory and minimizes trauma to the vein wall, making it ideal for fragile or sclerotic veins.
• The Notch (Side Port/Hole): Positioned proximally (just behind) the primary back-cut bevel, the notch acts as an auxiliary fluid pathway. In IV applications, if the primary lumen becomes occluded by a venous valve or the vessel wall, the notch ensures continuous fluid flow. Furthermore, in guidewire-assisted procedures, the notch provides a stable exit point for the guidewire.
