FAQ:

Q1: What are the unique clinical advantages of the Side-Port design compared to conventional front-port sampling?

A:​ The side-port opening effectively reduces fluid shear forces at the moment of aspiration, making it particularly suitable for handling high-viscosity (e.g., lipemic serum) or micro-particulate samples, minimizing sample carryover. Additionally, this design effectively prevents air bubbles from being sucked in due to excessive negative pressure when the needle touches the liquid surface, ensuring the accuracy of optical colorimetric module detection.

Q2: Can this metal sampling needle withstand routine high-temperature and high-pressure sterilization in the laboratory?

A:​ Absolutely. The main body of our sampling needle is made of 316L stainless steel and high-strength medical-grade alloys, offering excellent thermal stability and fatigue resistance. It can safely withstand autoclave cycles up to 135°C. Moreover, its robust physical properties allow it to maintain high dimensional accuracy even after tens of thousands of mechanical movements and frictions.

Q3: What is the emphasis on the sharpening process of the needle tip? How do you balance puncture trauma and penetration force?

A:​ We utilize plasma cutting combined with micro-grinding technology to shape the needle tip into specific geometries (e.g., Bevel Tip or Blunt Tip). For puncturing blood collection tube caps (like SST tubes), the optimized tip geometry easily penetrates the rubber stopper without generating debris, while minimizing damage to the tube cap to extend its service life.

Q4: If we need to integrate this into our self-developed new automation equipment, what technical support can you provide?

A:​ SHOMEA offers full-link deep customization services from ODM to OEM. Our engineering team can intervene in the early design stage to assist in optimizing the matching between the needle body and the fluid control system. Furthermore, we can customize mounting flanges, guide wire grooves, and height compensation structures according to your robotic arm interfaces.
