In the precision manufacturing of medical devices, material performance requirements are extremely stringent. PI Reinforced Tubing has become a key component in demanding applications such as vascular intervention and electrophysiology. Overview of PI Material PI, also known as polyimide, is a recognized high-performance organic polymer. Its outstanding features include: High strength: Even at microscale, PI maintains excellent mechanical strength. Excellent temperature resistance and thermal stability: This allows it to operate stably in a variety of complex medical environments, including high- and low-temperature sterilization processes. Although simple PI tubing offers excellent performance, braided reinforcement has been introduced to meet the higher demands of pushability, torsion resistance, and pressure resistance within the body for medical catheters. Braided Reinforcement Technology Braided reinforcement is a key production technology that incorporates a precisely woven reinforcement layer (usually metal wire or fiber) within the tubing wall to significantly: Improve compressive resistance: This prevents the tubing from deforming or collapsing when bent or subjected to external pressure. Improve pushability: This ensures that the catheter can effectively transmit force from the outside to the tip, enabling precise control by the physician.

A Multi-lumen Tubing is a single piece of tubing with multiple independent channels. This unique structure enables it to simultaneously accommodate and transport a variety of different substances, enabling multifunctional operation within a single catheter, significantly improving work efficiency and application flexibility. Core Advantages of Multi-lumen Tubing The main advantage of a multi-lumen tubing lies in its multi-channel design. Each lumen operates independently, without interfering with each other, and can simultaneously accommodate guidewires, medications, gases, or other fluids. For example, during interventional procedures, a physician can administer medication through one channel while simultaneously manipulating a guidewire through another, streamlining the procedure and minimizing patient trauma. This integrated functionality makes multi-lumen tubings a vital tool for complex medical procedures. Sophisticated Production Process: Extrusion Technology Manufacturing high-quality multi-lumen tubing is a skill-intensive process. It requires highly precise extrusion technology to ensure extremely tight dimensional tolerances within each lumen and excellent overall stability and mechanical properties.

In modern medicine, precision and safety are crucial prerequisites for successful surgery. When it comes to tubing used to deliver fluids to patients, many people think of standard IV tubing. However, in specialized scenarios, such as PCI procedures, standard IV tubing is no longer suitable, and High Pressure Braided Tubing is essential. These two seemingly similar tubing types actually differ significantly in structure, function, and operating environments. Structure and Materials: Key to Withstanding Pressure Standard IV tubing is mostly single-layer, typically made of PVC or silicone. It's flexible and lacks additional support. This design is sufficient for routine infusions or drug injections, as these procedures occur under normal pressure. High Pressure Braided Tubing, on the other hand, utilizes a multi-layer composite design. The most important layer is the braided reinforcement layer embedded in the tubing wall. This mesh, made of metal or high-strength fiber material, acts as a protective layer for the tubing, enabling it to withstand higher pressures. Furthermore, High Pressure Braided Tubing often utilizes medical polymer materials such as PEBAX and TPU, ensuring stable form and performance even under high pressure. Functions and Applications: Conventional and Specialized Ordinary IV tubing has a wide range of applications, primarily for procedures requiring normal pressure and low flow rates, such as blood and fluid transfusions. However, it cannot withstand high flow rates or high pressure injections. If misused in high-pressure applications, it can easily cause tube wall expansion or even rupture, potentially resulting in serious consequences. High Pressure Braided Tubing is designed for specific high-pressure environments. During procedures such as percutaneous coronary intervention (PTCA), physicians need to deliver contrast media into the coronary arteries quickly to obtain clear images. The injection pressure during this process can reach hundreds or even thousands of psi. High Pressure Braided Tubing, with its excellent pressure resistance, ensures that the contrast media reaches the target site quickly and stably. Its kink-resistant properties also make the procedure smoother and reduce unexpected situations. Safety and Precision: Directly Impacting Surgical Outcomes Ordinary IV tubing expands and deforms under high pressure, making it difficult to precisely control the injection dose and flow rate. This poses a significant risk in applications requiring precise drug delivery. It also increases the likelihood of tubing rupture. High Pressure Braided Tubing avoids these problems. The reinforced layer virtually prevents the tubing wall from expanding under high pressure, ensuring stable and controllable injection dosages. This performance not only improves operational accuracy but also significantly reduces the risk of tubing failure. Conclusion: The Right Choice for Different Needs In summary, High Pressure Braided Tubing and standard IV tubing differ fundamentally in structure, material, function, and safety. Standard IV tubing is suitable for general medical use, while High Pressure Braided Tubing is an irreplaceable specialized tool for high-pressure, precision procedures. While similar in appearance, their differing internal designs determine their respective roles in clinical applications.

Introduction to balloon tubing Balloon tube is a high-precision, specialized extruded tubing. Its core function is to serve as the raw material for the balloon body of a balloon dilatation catheter. These tiny balloons can be precisely delivered into the human body via a catheter during surgery to dilate narrowed blood vessels or cavities. For example, when a coronary artery or peripheral blood vessel is blocked, doctors use a balloon-loaded catheter to deliver it to the affected area to dilate and restore blood flow. The manufacturing precision and superior performance of balloon tubes ensure the success of these critical surgeries. Core Applications Balloon tubes are primarily used to manufacture the balloon body of a balloon dilatation catheter and are a core and critical component of the tube. As an innovator in this field, Ningbo LINSTANT Polymer Materials Co., Ltd. is striving to transcend the traditional role of a component supplier and become an integral part of its customers' products. Core Characteristics and Technical Requirements Manufacturing high-quality balloon tubes is a technical challenge that must meet extremely stringent requirements.

Even the slightest deviation can lead to uneven balloon inflation, compromising surgical outcomes and even posing safety risks. It's through specialized companies like Ningbo LINSTANT Polymer Materials Co., Ltd., which precisely match requirements during the collaborative design phase, that strict tolerance control is ensured. Mechanical Properties Balloon tubes must possess excellent mechanical properties, such as superior tensile strength and ductility, to prevent rupture or deformation during catheter insertion and balloon inflation. They must also possess excellent pressure resistance to withstand high-pressure inflation without bursting. Balloon Tube Manufacturing Process: Precision Extrusion Technology The production of balloon tubing primarily relies on precision extrusion technology. This process requires highly automated equipment and precise temperature and pressure control. A qualified manufacturer must possess not only advanced extrusion equipment but also sophisticated craftsmanship. Every step, from raw material mixing and melt temperature control to cooling and winding speed adjustment, is crucial. Ningbo LINSTANT Polymer Materials Co., Ltd. leverages its extensive extrusion experience and continuous technological innovation to provide customers with balloon tubing featuring excellent mechanical properties and stable, consistent tolerances, transforming catheter technology into a core competitive advantage for their products.
