—— SHOMEA Medical-Grade Stainless Steel Piercing Needles with Luer  ——

1. Medical-Grade Stainless Steel Construction

 Crafted from 316L or 304L medical-grade stainless steel, these needles comply with ISO 13485, ASTM F138, and USP Class VI standards. The material ensures exceptional biocompatibility, corrosion resistance, and durability, making them safe for repeated sterilization and long-term clinical use.

2. Precision-Engineered Tri-Bevel Tip

 The needle tip features a triple-bevel grind technology that creates a sharp, symmetrical, burr-free cutting edge. This design minimizes tissue trauma, reduces penetration resistance, and enables smooth, precise punctures — ideal for minimally invasive procedures such as injections, aspirations, or fluid delivery.

3. Luer Lock Connector for Secure Attachment

 Each needle is equipped with a precision-machined Luer lock hub (as seen in the image), allowing foolproof, leak-proof connection to syringes, catheters, or infusion sets. The knurled grip and threaded collar ensure stable handling and prevent accidental disconnection during critical procedures.

4. High-Polish Surface Finish for Hygiene & Safety

 The entire needle shaft undergoes electrolytic polishing, achieving a surface roughness (Ra) ≤ 0.2 μm. This ultra-smooth finish reduces protein adsorption and bacterial colonization, facilitating easy cleaning and compatibility with autoclaving, ethylene oxide, or gamma irradiation sterilization methods.

5. Calibrated Gauge & Consistent Dimensions

 Available in standard medical gauges (e.g., 12G, 14G, etc.), with tight dimensional tolerances (±0.01 mm). The uniform needle diameter and length ensure predictable flow rates and compatibility with automated medical equipment and manual syringes alike.

6. Sterile, Single-Use or Reusable Options

 Provided in individually packaged, sterile formats for immediate clinical use. Alternatively, non-sterile versions are available for facilities preferring in-house sterilization cycles, supporting both single-use safety and cost-effective reuse.

7. Wide Clinical Applicability

 Ideal for a broad range of medical and surgical applications:

 Intravenous/intramuscular injections

 Aspiration biopsy

 Irrigation & drainage procedures

 Catheter introducer systems

 Veterinary & dental applications

8. Compliance & Traceability

 Every batch is tested for mechanical strength, chemical resistance, and sterility assurance level (SAL 10⁻⁶). Full batch traceability, certification (CE, FDA 510(k) if applicable), and material test reports are provided to meet global regulatory requirements.
