SUS304 Medical Needle Cannula , Stainless Steel Needle Tube For Injection ISO9626

Medical Needle Tubes/Cannulas are the main metal part of the injection needles. They’re specifically designed to be the core component of hypodermic needles for medical and pharmaceutical. These needle tubes are generally manufactured by medical grade stainless steel 304 raw material due to its good resistant to corrosion, good durability and high hardness. Injection needle tubes are usually firstly welded from SUS304 stainless steel strips into capillary tubes. Then they are processed through reducing outer/inner diameter, straightening, cleaning, annealing, cutting into fixed length. And the capillary tubes will be grinded by machines and form a bevelled needle tip. Finally, needle tubes will be mechanical polished, cleaned, dried, inspected, and packaged. Our company is good at producing medical needle tubes from 10 Gauge to 34 Gauge and professional in customizing special needle tubes special needle tips (eg., three-face bevel, five-face bevel, blunt, back-cut, back-eye, quincke tip, etc.) according to clients’ drawings. Our needle cannulas are mostly used for medical devices, like injection needles, infusion needles, blood lancet, irrigation needles, catheters, and so on. Their manufacture is complied with ISO9626, ISO7864 international standards.

Regular Size Chart:

Key Features:

• Biocompatibility: Due to SUS304 stainless steel material.
• High Strength and Rigidity
• Sharpness Potential: Can be ground to an extremely sharp, burr-free needle tip.
• Excellent Corrosion Resistance
• Surface Finish: A mirror smooth finish, both inside and outside, minimizes patient discomfort, tissue damage.
• Consistency: Manufactured according to ISO 9626.

Different Types of Needle Tip Shapes:

The needle tube is cut and ground to form the bevel tip. The tip shape and bevel angle are critical for penetration smoothness.

• Regular Bevel: A standard needle tip.
• Short Bevel: A shorter needle tip for better control, often used in regional anesthesia.
• Pencil Point: A non-cutting end-closed tip that separates tissue fibers, designed for spinal anesthesia and lumbar punctures.
• Quincke Point: A sharp, cutting tip with a long bevel, used for precise cutting.

Main Injection Areas:

The gauge and length of the needle tube determine its application area.

• Intravenous Injection(IV): Typically 18G - 22G. Used for administering fluids, blood products, or medication directly into a vein.
• Intramuscular Injection (IM): Typically 21G - 23G. Used for injecting medication into large muscle groups (e.g., deltoid, gluteus).
• Subcutaneous Injection (SC): Typically 25G - 30G. Used for injecting into the fat layer under the skin (e.g., insulin, vaccines).
• Intradermal Injection (ID): Typically 26G - 30G. Used for injecting into the top layers of the skin (e.g., TB tests, allergy tests).
• Dialysis And Apheresis: Typically 15G - 17G. Used for procedures requiring high flow rates.
• Spinal / Epidural: Typically 25G - 27G. Used for anesthesia administered into the spinal canal.

Different Applications:

• Medical Syringes
• Hypodermic Needles
• IV Catheters
• Biopsy Needles
