32G SUS304 Stainless Steel Needle Tube For Insulin Injection , Bevelled Tip , 4mm 5mm

The stainless steel insulin needle tube is a high-precision, ultra-thin tubular component with bevel tip specifically designed and manufactured to serve as the core part of a hypodermic needle for insulin pen injectors and syringes. It is crafted from SUS304(AISI 304) Stainless Steel because of the good corrosion resistance and formability. The "Bevelled Tip" refers to the needle's point, which is sharpened at a precise angle to create a lancet-like edge, enabling smooth and minimally traumatic penetration of the skin and subcutaneous tissue. In essence, this is the critical component that ensures the safe, accurate, and comfortable delivery of insulin for individuals with diabetes. Stainless steel insulin needle tubes' outer diameter ranges from 30G to 33G. And the common lengths are 4mm, 5mm, 6mm. Our company specializes in different insulin needle tubes according to customers' detailed drawings. In addition to insulin needle tubes, we can also provide semi-finished needle tubes, like hypodermic needle tubes, dental needle tubes, blood collection needle tubes, veterinary needle tubes, beauty needle tubes and so on.

Key Advantages:

• Superior Corrosion Resistance: SUS304 is an austenitic stainless steel containing 18% Chromium and 8% Nickel. This composition provides excellent resistance to corrosion from bodily fluids and the insulin formulation itself, preventing rust and contamination.
• High Strength and Ductility: Despite its thinness, the material has high tensile strength, allowing it to resist bending or breaking during injection. Its ductility enables the complex process of forming a sharp, consistent bevel.
• Excellent Biocompatibility
• Ultra-Sharp Bevelled Tip: It is the primary factor in achieving a painless or near-painless injection.
• Smooth Inner and Outer Surface: The tubes are drawn and polished to have a very low surface roughness. A smooth inner surface prevents insulin from sticking and ensures accurate dosing, while a smooth outer surface minimizes friction and tissue drag.
• Consistency and Reliability

Injection Areas:

The choice of needle length is directly related to the recommended injection sites and technique.

• 4mm, 5mm, and 6mm: These are recommended for all adult patients. They are designed for subcutaneous injection into the fatty tissue just below the skin. When used correctly (typically at a 90 degree angle without pinching the skin), they reliably deliver insulin into the subcutaneous layer.
• 8mm and 12.7mm: These lengths were more common in the past. They may still be used by some individuals but carry a higher risk of intramuscular injection if not administered carefully, often requiring a skin pinch and a 45 degree angle. Their use is declining in favor of shorter needles.

Primary Injection Sites:

• Abdomen (avoiding the navel)
• Thighs (front and outer sides)
• Buttocks
• Back of the upper arms

Different Applications:

• Diabetes Management(Main Usage): Insulin delivery via pen injectors and syringes.
• Hormone Therapy
• Other Subcutaneous Biologics: For conditions like osteoporosis, rheumatoid arthritis.
• Cosmetic Mesotherapy: For the intradermal or subcutaneous delivery of vitamins, enzymes, etc.
