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.
