FAQs:
Q: What is an "internal/external piercing needle"? What are its unique applications compared to ordinary piercing needles?
A: An "internal/external piercing needle" typically refers to a compound or cannula-style piercing structure. Its core purpose is to puncture without compromising the integrity of a sealed system. For instance, the outer needle cuts or dilates the skin/outer membrane, while the inner needle penetrates deeper sealing films (such as IV bag ports, rubber stoppers, or vascular septums), thereby enabling sterile access, bidirectional drainage, or pathway creation within enclosed spaces. It is especially suitable for ICU, anesthesiology, and other scenarios requiring strict aseptic conditions.
Q: What tolerances for inner/outer diameter and surface finish can be achieved? How does this affect fluid flow?
A: Utilizing precision cold drawing and centerless grinding processes, the inner diameter tolerance of the needle tube is controlled within ±0.02mm, and the surface roughness can reach Ra < 0.1μm (mirror-grade). Extremely high dimensional accuracy ensures stable and predictable flow output, while the ultra-smooth inner wall significantly reduces fluid resistance and turbulence. This is critical for applications requiring precise medicine delivery (e.g., anesthetics, chemotherapy) or intravenous infusions prone to air embolism.
Q: Can we customize special tip geometries (e.g., side holes, double bevels) or non-standard lengths?
A: We support comprehensive non-standard customization. Leveraging 5-axis precision grinders and laser processing technology, we can manufacture various special tip geometries, such as Side Ports, dual-core分流 (split flow), Flared tips, etc. Additionally, the needle length, outer diameter, and the material of the Luer Lock (metal/plastic) can be personalized according to your medical device registration requirements or specific clinical needs.
