SS304 Intravenous Indwelling Needle Tube For Medical IV Catheter , Back Cut Needle Tip

SUS304 stainless steel back-cut intravenous (IV) indwelling needle tube is a precision medical-grade needle tube specially manufactured for disposable and reusable medical IV catheter systems. Complying with ISO 9626 and GB/T 18457 medical stainless steel needle tube standards, it adopts high-purity medical SUS304 austenitic stainless steel as the raw material, with a unique back-cut needle tip structure different from conventional straight bevel needle tips. As the core puncture component of IV indwelling catheters, it is mainly used for skin and venous puncture. After successful venipuncture, the stainless steel needle core is withdrawn and discarded, leaving the flexible plastic catheter indwelling in the vein for continuous intravenous infusion, medication injection, and venous transfusion treatment. This IV indwelling needle tube integrates excellent biocompatibility, precise dimensional stability and low-trauma puncture performance, and is a core consumable in clinical venous transfusion.

Key Features of SUS304 Back-Cut Needle Tubes:

Ultra-Low Trauma Puncture Performance

Medical-Grade Biocompatibility

Excellent Corrosion Resistance

Precise Dimensional Stability

High Mechanical Stability & Durability

High Rigidity with Thin Wall

Main Injection Areas of Back-Cut IV Indwelling Needles:

Upper Extremities (Most Common): Cephalic vein, Basilic vein, and Median Cubital vein (often using 18G-22G).

Dorsal Hands & Wrists: The metacarpal venous network (primarily 22G and 24G for smaller, superficial veins).

Lower Extremities: Great Saphenous vein (used in emergency situations or pediatrics; typically 20G-24G).

Scalp Veins (Neonates/Pediatrics): Superficial temporal, frontal, and occipital veins (strictly 24G or 26G due to vessel fragility).

External Jugular Vein: For rapid fluid resuscitation in trauma (large gauges 14G-16G).
