SUS304 Medical Stainless Steel Injection Needle Tube , Lancet Three Bevel Point , ISO9626 ISO7864

Stainless steel lancet triple bevelled point needle tubes are usually used for medical injection and infusion. The tri-bevelled needle point design reduces the patient's discomfort, uncomfortable feeling and tissue trauma. This kind of needle point has two blade surfaces and there are two different primary bevel angles, that is regular bevel(12-15°), short bevel(18-20°). The regular bevel point needle tubes are generally used for injection and the short bevel point needle tubes are used for blood collection. For different applications. the stainless steel medical needle tubes will have different needle points, like flat bevel point, three bevel point, five-bevel point, blunt point, back-eye point and so on. All the special needle points can be customized according to customers' drawings. Our ISO9626 SUS304 SUS316L stainless steel needle tubes are all inspected conforming to ISO18457 inspection standard.

Why do we use medical grade stainless steel 304 material?

• Corrosion Resistance: Withstands exposure to bodily fluids and sterilization processes.
• Durability: Maintains structural integrity during insertion.
• Biocompatibility: Safe for contact with human tissues, meeting ISO 9626 standards.

Three Bevel Point Design:

1. What is a Bevel?

The angled cutting surface at the needle tip. A three-bevel design features three precision-ground facets:

2. Advantages:

• Sharper Tip: Minimizes insertion force and patient discomfort.
• Reduced Coring: Prevents tissue plugs from blocking the needle lumen.
• Controlled Penetration: Ideal for subcutaneous (SC), intramuscular (IM), or intravenous (IV) injections.

3. Comparison:

• Single-bevel needles may require more force, increasing discomfort.
• Triple-bevel tips are common in high-precision applications.

Needle Tube Specifications:

• Hollow Design: Facilitates fluid transfer (medication, vaccines, blood).
• Gauge (Diameter): Ranges from 10G (thick, for viscous fluids) to 34G (ultra-thin, for pediatric use).
• Length: Tailored to delivery depth (e.g., 4–25 mm for SC injections, 25–38 mm for IM).

Applications:
1. Common Uses:

• Vaccinations.
• Diabetes Care: Insulin delivery.
• Blood Collection: Phlebotomy or capillary sampling.
• Dermatology: Intradermal injections.

2. Specialized Settings: Emergency medicine, veterinary use, and self-administration.
