The front end features a high-precision micro-polished blunt tip (non-sharp bevel), treated with biocompatible mirror polishing (Ra value can be below 0.2μm). This design effectively disperses contact stress when contacting fragile tissues (e.g., ocular vitreous, brain tissue, or neonatal vessels), preventing puncture trauma.
The tail end (proximal connection end) features a precisely stamped side hole, with the hole-to-tube diameter ratio optimized for fluid dynamics (typically 1/3 to 1/2 of the tube diameter).
The entire tube body (except for the side hole) is manufactured using an automatic laser seamless welding sealing process, ensuring no visible gaps or weld protrusions. This fully enclosed structure not only guarantees absolute sterility upon leaving the factory but also provides excellent tensile strength and pressure resistance (capable of withstanding repeated autoclave sterilization cycles).
FAQs:
Q: In which specific medical departments or surgical scenarios is this tube typically used?
A: This tube is widely used in departments with extremely high requirements for tissue protection. Common application scenarios include: Ophthalmology Surgery (silicone oil/gas filling and drainage after vitrectomy), Neurosurgery (cerebrospinal fluid drainage, intraventricular medicine perfusion), Neonatology (umbilical vein catheters, micro-dose medicine infusion), and Interventional Radiology (auxiliary guidance for fine vascular sheaths).
Q: What are the special features of your blunt tip tube in terms of material and surface finish? Can it meet medical sterilization requirements?
A: We offer two material options: medical-grade 304/316L stainless steel or high-purity medical polymers (e.g., PEEK, PTFE). The surface is treated with medical-grade electropolishing or plasma polishing, controlling roughness (Ra) at a very low level, which is not only smooth and resistant to wall adhesion and scaling but also easily sterilized by high-temperature high-pressure steam (SAL 10^-6) or ethylene oxide (EO) sterilization. The materials themselves comply with ISO 10993 biocompatibility standards, are non-cytotoxic, and can be left in the body for extended periods.
Q: Can the size and number of side holes be customized? Will this affect the patency rate of the tube?
A: Yes, the diameter (typically 0.1mm-1.0mm) and number (1-5) of side holes can be customized according to the customer's clinical needs. Our design team optimizes the hole layout through Computational Fluid Dynamics (CFD) analysis to ensure excellent patency (>95%) even at minimal flow rates. As long as the total side hole area does not exceed a reasonable proportion of the tube's cross-sectional area (usually <30%), it will not affect the overall hydrodynamic performance or increase the risk of blockage.
