SHOEAM Medical-Grade Hypodermic Tubing

• The entire tube (including snake bone segments) undergoes ultra-precise electrolytic polishing and mirror grinding, achieving a surface roughness as low as Ra < 0.05μm. This extreme smoothness not only significantly reduces frictional resistance with vessel walls and tissue fibers, making the insertion process smoother and minimizing tissue damage, but also effectively prevents platelet adhesion and thrombus formation. It complies with ISO 10993 biocompatibility standards, safely usable for long-term or short-term in vivo contact, meeting the stringent requirements of high-end interventional fields such as cardiovascular and neurosurgery.

FAQs:

Q: What is the "Snake Bone" structure? What are its core advantages over standard hypodermic tubes?

A: The "Snake Bone" refers to a bionic micro-joint structure​ formed on the hypodermic tube body via precision laser cutting and micro-bending technology. Compared to standard hypodermic tubes, its core advantages are "flexible guidance" and "kink resistance."​ While standard tubes tend to collapse and block when bent, the snake bone structure allows the tube to maintain a high patency rate (close to 100%)​ even at an extremely small bending radius (as low as 5 times the tube diameter), while also enabling precise distal steering through rotation.

Q: With the snake bone structure, can liquids or guidewires still pass through smoothly when the tube is bent?

A: Absolutely. Our design ensures continuity of the fluid channel. The micro-joint gaps of the snake bone are specially designed, combined with ultra-smooth internal mirror polishing (Ra<0.05μm), ensuring ≥95% of the original flux efficiency​ even at maximum bending angles. For scenarios requiring guidewire passage, the smooth, protrusion-free transition design prevents wire snagging, ensuring smooth delivery of interventional devices.

Q: What is the minimum achievable pitch and wall thickness for the snake bone? Do you support non-standard customization?

A: Thanks to our high-precision laser micromachining technology, the pitch (single segment length) of the snake bone can be as small as 0.3mm, and the wall thickness can be as thin as 0.05mm. We fully support non-standard customization, including the shape of the snake bone (e.g., spiral, zigzag), pitch density, the outer diameter of the hypodermic tube (0.3mm-3.0mm), and the overall length. Please provide your engineering drawings or technical requirements, and we will evaluate the feasibility for you.

Q: Will this structure trap debris or be difficult to clean? Is it sterilizable?

A: Despite the complex appearance, our snake bone structure undergoes precise geometric optimization, featuring no dead ends or deep pits. Combined with a mirror finish of Ra<0.05μm, contaminants are extremely difficult to adhere to. The product is compatible with autoclaving, EO sterilization, and low-temperature plasma sterilization. For reusable products, we recommend using dedicated tube cleaning brushes for flushing to ensure thorough cleaning.
