Brief: Join us for a close-up look at this solution and see it in action. In this video, we demonstrate the 304 stainless steel capillary side hole puncture spray needle, showing how its precision side-hole design enables targeted fluid delivery and aspiration. You'll see the manufacturing process, from tip sharpening to side-hole drilling, and explore its applications in medical procedures and industrial processes where accurate radial dispersion is critical.
Related Product Features:
  • Constructed from medical-grade 304 stainless steel for excellent corrosion resistance and strength.
  • Features a sharp, closed tip for easy penetration and one or more precision-drilled side holes near the distal end.
  • Enables radial or angled fluid dispersion, minimizing forward jet pressure for targeted delivery in confined spaces.
  • Available in outer diameters from 0.3 mm to 2.0 mm and lengths from 50 mm to 300 mm to suit various applications.
  • Side holes are micro-drilled or laser-ablated with precise positioning and diameter tolerances for consistent performance.
  • Electropolished internal and external surfaces ensure smooth flow and minimize particle adhesion.
  • Compatible with standard Luer Lock hubs for medical use or various industrial fittings for lab and manufacturing applications.
  • Customizable hole patterns, tip styles, and material grades like 316L for enhanced corrosion resistance.
FAQs:
  • What are the primary applications for this side-hole puncture needle?
    This needle is used in medical interventional procedures like angiography, abscess drainage, nerve blocks, and tumor ablation. It's also applied in laboratory settings for chromatography and micro-dispensing, as well as industrial processes such as precision lubrication and adhesive application.
  • How does the side-hole design benefit fluid delivery compared to standard needles?
    The side-hole configuration allows for radial or angled dispersion of fluids, reducing high-velocity forward jetting. This enables targeted delivery or sampling adjacent to the needle tip, which is essential for coating surfaces, filling cavities, or avoiding damage to delicate tissues or structures beyond the tip.
  • What customization options are available for this needle?
    The needle can be customized in terms of the number, size, position, and angle of the side holes, as well as the tip style (sharp, blunt, or specially shaped). Material grades like 316L are available for enhanced corrosion resistance, and various end connections can be specified based on application needs.
