Blesson | FEP IV catheter cannula extrusion line

一. Product Overview of the Blesson FEP IV catheter cannula extrusion line

The Blesson FEP IV catheter cannula extrusion line is a medical tubing extrusion line specifically developed for fluoroplastic indwelling needle cannulas. It is primarily suitable for the production of indwelling needle cannulas made from FEP and other fluoroplastic materials. The tubing produced on this line exhibits excellent resistance to acidic and alkaline medicinal solutions and can withstand chemotherapeutic agents and various drug solution environments. In addition, the inner wall of the tubing has a low friction coefficient and a smooth surface, which helps reduce blood adhesion and the risk of clotting, thereby enhancing the safety and comfort of indwelling needles in clinical use.

In terms of application scope, the FEP indwelling needle cannulas produced on this line are mainly suitable for chemotherapy, long-term intravenous infusion, and other medical scenarios. They can also be used in intravenous indwelling needles, safety indwelling needles, and other medical device products requiring long-term venous access support. Their material performance and tubing precision meet the requirements of medical indwelling needles for corrosion resistance, low friction, anti-coagulation, and dimensional stability.

二. Overview, Core Configuration, and Equipment Advantages of the Blesson FEP IV catheter cannula extrusion line

(1) Overview of the Blesson FEP IV catheter cannula extrusion line

The Blesson FEP IV catheter cannula extrusion line is designed to meet the requirements for high-precision, clean, and stable production of medical FEP indwelling needle cannulas. It integrates extrusion, high-temperature plasticization, cooling and sizing, online diameter measurement, synchronized haul-off, winding or cutting, and data traceability. The entire line operates cleanly and with low noise, making it suitable for cleanroom production environments. It can continuously and stably produce micro medical tubing and supports the production of tubing with a radiopaque stripe.

(2) Core Configuration of the Blesson FEP IV catheter cannula extrusion line

1.Corrosion-resistant alloy extrusion components: To address the corrosion that readily occurs during the high-temperature extrusion of fluoroplastics, the equipment adopts corrosion-resistant alloy extrusion components, thereby improving the durability of key components such as the screw and barrel and ensuring stable material plasticization.

2.Precise high-temperature control system: Equipped with a precise high-temperature control system, the equipment enables accurate multi-zone temperature control, ensuring uniform plasticization of FEP material and reducing fluctuations in tubing dimensions.

3.SEW servo drives and Siemens PLC control:Equipped with SEW servo drives and a Siemens PLC control system, the line achieves closed-loop synchronous speed control between the extruder and the haul-off, keeping the extrusion speed matched with the haul-off speed and improving the consistency of outer diameter and wall thickness.

4.Sealed stainless-steel cooling system: A sealed stainless-steel cooling structure provides uniform cooling, reduces the risk of external contamination, and facilitates cleaning and maintenance.

5.Online diameter measurement and micron-level precision control: An online diameter measurement device is configured to monitor the tubing outer diameter in real time and provide feedback adjustment, achieving micron-level precision control.

6.Radiopaque stripe production and rapid mold changeover: The line can produce tubing with a radiopaque stripe to meet clinical radiopacity requirements. It also supports rapid mold changeover, facilitating quick switching between products of different specifications.

7.Full-process data traceability: Data recording and traceability can be performed throughout the production process, providing a basis for medical quality management and quality analysis.

(3) Overall Equipment Advantages of the Blesson FEP IV catheter cannula extrusion line

The FEP IV catheter cannula extrusion line offers overall advantages including corrosion resistance, high precision, high stability, cleanliness, and low noise. Through the combination of closed-loop synchronous speed control between the extruder and haul-off and online diameter measurement control, the line effectively ensures tubing dimensional precision and batch-to-batch consistency. The sealed stainless-steel cooling and low-noise clean design make it suitable for cleanroom environments. Rapid mold changeover and full-process data traceability further enhance production flexibility and medical quality assurance capability.
