SHOMEA Multi-Hole Perforated Tube

Product Specification

• The arrangement angle and diameter ratio of the four holes​ are optimized via computational fluid dynamics (CFD) simulation, ensuring efficient and uniform medium distribution​ during liquid or gas transmission, avoiding local pressure concentration or fluid dead zones. This design is particularly suitable for medical devices requiring precise fluid path control, such as medicine infusion catheters, multi-lumen drainage tubes, hemodialysis circuits, enhancing therapeutic efficiency and patient comfort.

• The product is processed and packaged entirely in a class 10,000 cleanroom environment, with surface roughness Ra≤0.4μm, free of oil, metal debris, or oxidation residues. It complies with GMP (Good Manufacturing Practice) for medical devices, ensuring no particle shedding or contamination risk​ during implantation or interventional use, safeguarding surgical safety and patient health.

FAQs:

Q: How are the holes of this perforated tube processed? Can you guarantee the positional accuracy and edge quality of the holes?

A: We utilize high-energy fiber laser drilling technology​ to precisely process micro-holes on the tube wall without mechanical stress. Each hole has a diameter tolerance controlled within ±0.02mm, with smooth, burr-free edges. The four holes are accurately arranged via a CNC positioning system, ensuring repeatability in hole spacing and distribution angles up to ±0.1°, fully meeting the stringent requirements of precision applications such as medical catheters and drainage tubes.

Q: Is the tube diameter, wall thickness, and hole spacing of the perforated tube customizable? What is the minimum size achievable?

A: Yes, we offer full-parameter customization services. The tube diameter range is from Φ0.3mm to Φ5.0mm, wall thickness can be as thin as 0.05mm, and hole spacing can be adjusted at the micron level​ according to customer design requirements (minimum center distance up to 0.5mm). Please provide your drawings or technical parameters, and our engineering team will provide you with the optimal process solution.

Q: What surface treatment methods are available for the product? Will it affect the cleanliness of the inner hole walls?

A: We offer various surface treatment methods including electrolytic polishing, passivation treatment, and Parylene coating. Among them, electrolytic polishing​ not only enhances the surface smoothness of the tube body but also effectively reduces the microscopic roughness and residues inside the hole walls, facilitating subsequent sterilization processes (such as autoclaving or ethylene oxide sterilization), ensuring the high cleanliness and sterile safety​ of the product in medical environments.

Q: In which medical fields is this perforated tube mainly applied? Are there any relevant application cases?

A: This product is widely used in minimally invasive surgical catheters (e.g., percutaneous nephrostomy drainage tubes, biliary drainage tubes), medicine infusion systems, extracorporeal circulation tubing, diagnostic equipment fluid channels, and other fields. We have provided OEM/ODM supporting services​ for many well-known medical device companies and accumulated extensive experience in pre-clinical testing and mass production delivery, capable of providing targeted design and validation support based on your specific application scenarios.
