ISO9626 SUS304 Medical Stainless Steel Back Eye AV Fistula Needle Tube For Hemodialysis
Overview:
Medical AV fistula needle tubes are designed with a distal opening at the needle tip and a notched opening (also known as "back eye") on the sidewall near the needle tip. AVF needle tubes are also specifically designed to be the core component of needles used for accessing arteriovenous (AV) fistulas or grafts during hemodialysis procedures. The AVF needle tubes are mainly made from medical grade stainless steel 304 material grade due to its excellent corrosion resistance. This dialysis needle tube forms a important fluid pathway for blood extraction (arterial needle) and return (venous needle) during hemodialysis. The back eye of the AV fistula needle tube is a crucial design, especially for the arterial needle tubes, which can avoid the complete occlusion of the lumen when the needle tip is suctioned against the vessel's wall during the process of draw blood. The back eye can also enhance safety and efficiency by ensuring consistent of blood flowing. All AVF needle tubes are manufactured according to ISO9626 standard, ensuring the excellent dimensional precision, surface finish, material purity, and mechanical properties.
As one of the biggest stainless steel needle tubes manufacturer, YUHONG GROUP can produce almost 13 billion pieces each year. We can not only manufacture the medical needle tubes with standard sizes, but also custimize according to cllients' drawings or samples. Our factory has been certified by ISO13485 standard. In addition to AVF needle tubes, we can also provide injection needle tubes, hypodermic needle tubes, insulin needle tubes, blood collection needle tubes, indwelling needle tubes, and so on.
Features And Benefits Of AVF Needles:
- Back Eye
- Superior Corrosion Resistance
- High Strength
- Smooth Surface Finish
- Precision Ground Tip(Sharp, Smooth, Burr-free Bevel)
- Rigidity
Key Applications:
- Arterial Needle Tubes: to draw the blood from the patient's AV fistula or graft to the dialysis machine. The back eye is critical here.
- Venous Needle Tubes: to return the purified blood to the patient's AV fistula or graft from the dialysis machine. Venous needle tubes typically have only a bevel.
Stainless steel medical AV fistula needle tubes provide a secure, rigid, high-flow pathway for blood between the patient's vascular access and the extracorporeal dialysis circuit.
