• The 20G (inner diameter ≈0.61mm) specification balances flow efficiency and tissue trauma: ensuring rapid and smooth infusion of medicine/contrast agents/nutritional solutions (flow rate up to 50-100mL/min, depending on pressure difference), while avoiding excessive dilation of the puncture channel, suitable for medium-to-long-term indwelling or repeated puncture scenarios.
• The inner wall is treated with electrolytic polishing + ultrasonic cleaning, achieving a surface roughness Ra ≤0.2μm, forming an ultra-smooth channel that effectively prevents adhesion of medicine crystals, blood, or tissue debris, reducing blockage risks; additionally, the mirror finish facilitates post-operative cleaning and sterilization validation, complying with GMP/ISO 13485 cleanliness standards.
• The tail can be optionally equipped with a standard Luer Lock or Luer Slip connector, seamlessly compatible with mainstream syringes, infusion pumps, and catheter systems, reducing connection dead volume, and improving infusion accuracy and operational efficiency.
• Passed 100,000-cycle puncture fatigue test, high-pressure steam sterilization resistance test (134℃), biocompatibility test (ISO 10993 full items), ensuring dimensional stability, structural strength, and sterility under high-frequency clinical use and high-temperature sterilization cycles, meeting stringent demands in hospitals, laboratories, veterinary medicine, and other scenarios.
FAQs:
Q: What medical scenarios is the 20G specification suitable for? What is the flow rate?
A: 20G (inner diameter ~0.61mm) is a universal high-flow specification. It is ideal for fluid infusion, rapid rehydration, contrast agent injection, and certain surgical irrigation requiring higher pressure (e.g., orthopedics, urology). Under standard pressure, its flow rate can typically reach 50-100 mL/min, efficiently completing medicine delivery or irrigation tasks.
Q: The beveled tip is very sharp; how is safety and smoothness ensured during puncture?
A: Our needle tips adopt micro-tapered polishing and diamond-cut edge technology. Although extremely sharp to reduce puncture resistance, the edges are finely ground to be smooth and burr-free. This ensures smooth, non-tearing entry into skin or tissue, while effectively controlling the lateral wound size and tissue fluid leakage.
Q: What type of tail interface does this needle have? How is it connected to existing equipment?
A: The tail features a standard Luer Lock interface (or confirmed as a smooth straight tube/threaded interface based on the specific image). You can directly screw or insert it into matching medical tubing, syringes, or infusion pumps. If it's a smooth straight tube design, we recommend using it with a Luer adapter sleeve or dedicated fixing device to ensure a secure, leak-free connection.
