SUS304 17G RW Disposable Medical Stainless Steel Tri-bevelled Needle Tube For IV Catheter

SUS304 17G RW Disposable Medical Stainless Steel Tri-bevelled Needle Tube For IV Catheter

A ISO9626 SUS304 Medical Grade Stainless Steel Tri-bevelled Needle Tube is a precision-engineered hollow needle specifically designed as the introducer stylet (inner cannula) for peripheral intravenous (IV) catheters. Manufactured from medical-grade SUS304 (AISI 304) austenitic stainless steel, this component features a unique triple-bevel geometry at its distal tip. Unlike standard single-bevel hypodermic needles, the tri-bevelled design creates a lancet-like point that minimizes insertion force, reduces vein trauma, and facilitates smooth catheter threading. As one of the largest manufacturer of stainless steel medical needle tubes, YUHONG GROUP is professional in producing various kinds of medical needles, such as injection needle, infusion needle, puncture needle, IV needle, blood collection needle, blood lancet, dental needle, and so on. We can customize many needle tips, including lancet bevel tip, back cut tip, back eye tip, blunt tip, pencil tip, etc.. In addition to standard aizes(10G-34G), we can also provide needle tubes with non-standard sizes.

The triple bevel consists of three distinct angular facets ground into the needle tip:

• Primary Bevel (Heel): The longest grind, creating the main cutting edge.
• Secondary Bevels (Two Lateral Facets): Two shorter, symmetrically angled grinds that intersect the primary bevel, forming a sharp conical point.

Advantages for IV Catheters:

• Reduced Penetration Force: Up to 30% less force required compared to single bevel.
• Improved Venipuncture Success: The sharp point creates a precise, clean incision through skin and vein wall without dimpling.
• Lower Hemolysis Risk: Cleaner puncture reduces red blood cell damage during blood sampling.
• Smoother Catheter Advancement: The transitional geometry prevents the needle tip from scraping the inside of the outer catheter sheath.

Key Features of SUS304 IV Catheter Needle:

• Triple Bevel Precision: Ultra-sharp lancet point reduces patient's discomfort and insertion force.
• High Corrosion Resistance: SUS304 passive layer withstands blood, saline, and common IV fluids.
• Excellent Formability: Cold-drawn to precise OD/ID tolerances without cracking.
• Non-magnetic (Weakly)
• Biocompatible
• Consistent Wall Thickness: Ensures uniform flexural strength – needle won't kink or buckle during insertion.
• Compatibility: Fits standard Luer lock and Luer slip hubs.

Applications Of Medical Needle Tubes:

• IV Catheters/Cannulas
• Injection Needle
• Infusion Needle
• Blood Collection/Sampling
• Medication Delivery
