PEBAX Double Lumen Tube

Customization of Medical Catheters Disposable PEBAX Black Double Lumen Tubing for Medical Devices

Introduction

Material：PEBAX（Thermoplastic Polyurethane）

Performance Advantages and Medical Applications of Medical PEBAX Black Dual-Lumen Tubing

Performance Advantages

1. Excellent Combination of Mechanical Properties

• High Elasticity and Flexibility: PEBAX material offers outstanding elasticity, making catheters very supple and capable of navigating tortuous anatomical pathways with ease, greatly enhancing patient comfort and reducing tissue trauma.

• High Kink and Crush Resistance: Compared to materials like silicone, PEBAX tubing is less prone to collapsing or kinking under compression or bending, ensuring continuous lumen patency, which is critical for vital drug delivery or monitoring.

• Superior Impact and Fatigue Resistance: Can withstand repeated manipulation and use without easy rupture, ensuring a long service life.

2. Lightweight and Ease of Handling

• PEBAX is one of the lightest polymers in the world, making devices easier and lighter to handle, which aids physicians in performing precise, prolonged procedures.

3. Exceptional Biocompatibility

• Medical-grade PEBAX complies with relevant international biocompatibility standards (e.g., ISO 10993), ensuring safe and reliable use in the body.

4. Chemical Stability and Purity

• Exhibits good resistance to a wide range of chemicals, including pharmaceuticals and disinfectants. The material is inherently plasticizer-free, preventing the leaching of harmful substances over time and ensuring stable performance.

5. Sterilizability

• Suitable for various sterilization methods, including Ethylene Oxide and Gamma Radiation sterilization.

6. Tailorable Properties and Advantages of Black Formulation

• Adjustable Performance: By varying the ratio of soft to hard segments in the polymer chain, the hardness, elasticity, and other mechanical properties of PEBAX can be precisely engineered to perfectly match specific application requirements.

• Black Formulation: The black PEBAX tubing is primarily designed for radiopacity. It is clearly visible under X-ray, allowing physicians to accurately position the catheter during interventional procedures. Additionally, the black color effectively blocks light transmission, protecting light-sensitive drugs.

7. Advantages of Dual-Lumen Structure

• Allows for multiple functions within a single catheter. For example, one lumen can be used for drug or nutrient delivery, while the other can be used for balloon inflation/deflation or pressure monitoring, enabling device miniaturization and functional integration.

Medical Applications

• High-End Interventional Catheters: Such as cardiovascular angiographic catheters, balloon dilatation catheters, and guide catheters, utilizing their trackability, kink resistance, and radiopacity.

• Neurovascular Devices: Microcatheters used for treating strokes and aneurysms, which require excellent trackability and kink resistance.

• High-Pressure Balloon Catheters: Commonly used in peripheral vascular and urological dilation procedures due to their high strength and burst resistance.

• Specialized Drainage Tubes and Delivery Systems: Used in complex clinical scenarios requiring separate drainage or infusion through multiple lumens.
