SUS304 Bevelled Tip Medical Stainless Steel Injection Needle Tube / Cannula ISO7864

The stainless steel needle tube (commonly called a Cannula) is a fundamental, high-precision, single-use component of the regular medical needle assembly, which is a small, hollow, bevel-tip tube, enabling safe and effective fluid delivery or withdrawal through the skin. These needle tubes are mainly manufactured by SUS304 medical grade stainless steel material for injection and infusion applications, conforming to the ISO7864 international standard. Some of needle tubes are made by SUS316L material for implant devices. The most common type of needle tubes is the injection needle tube, which has lancet bevel tip, such as three-bevel tip, five-bevel tip. The precision-ground bevelled tip (typically a "Regular" bevel angle) is designed for sharpness and smooth tissue penetration with minimal trauma and patient discomfort. The medical stainless steel injection needle tube forms the critical fluid pathway for subcutaneous(SC), intramuscular(IM), intradermal(ID), and intravenous(IV) injections, vaccinations, blood sampling, and other fluid transfer procedures.

Regular Sizes Of Injection Needle Tubes:

Main Features Of SUS304 Injection Needle Tubes:

• Sharp Bevelled Tip: For low penetration force, reduced pain, and minimal tissue damage.
• Excellent Corrosion Resistance
• High Rigidity to resist bending or kinking during the insertion and use.
• Smooth Internal And External Surface, reducing the friction during insertion and fluid flow resistance.
• High-precision manufacturing And Tight Tolerance to ensure good performance and flow characteristics.

Main Injection Areas of the Human Body:

• Subcutaneous(SC) Injection: The fatty tissue layer under the skin (e.g., insulin, vaccines). Typically Gauges: 25G-31G, Lengths: 4mm-16mm.
• Intramuscular(IM) Injection: Muscle tissue (e.g., vaccines, hormones). Typically Gauges: 20G-23G, Lengths: 25mm-50mm.
• Intradermal(ID) Injection: The top layers of the skin (e.g., tuberculosis tests, allergy tests). Typically Gauges: 26G-27G, Lengths: 10mm-16mm(short-bevel needles).
• Intravenous(IV) Injection: Accessing veins for fluid / medication administration or blood draw. Typically Gauges: 18G-22G mainly for access/draws, smaller diameter for fragile veins.

Different Applications Of Medical Stainless Steel Needle Tubes:

• Hypodermic Injections
• Aspiration for withdrawing fluids, such as blood sampling.
• Dental Injections for local anesthesia delivery.
• Veterinary Injections
• Connecting Tubing between connecting syringes to IV catheters or other devices
• Specialized Procedures, like injecting contrast agents and some dermatological procedures.
