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.
