SHOMEA Customized 20G Stainless Steel Back-Beveled Needle

Product Specification

PRODUCT DESCRIPTION:

• 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.
