PU Tubing Introduction

Material：PU（Polyurethane）

Performance Advantages and Medical Applications of Medical-Grade PU Plastic Transparent Double-Lumen Tubes

Performance Advantages

1. Excellent Biocompatibility

• Made from medical-grade polyurethane (PU), it complies with strict biocompatibility standards (e.g., ISO 10993), is non-irritating and non-toxic to human tissues, and is suitable for both long-term and short-term implantation and contact.

2. Superior Flexibility and Kink Resistance

• PU material offers exceptional flexibility and elasticity. It can bend with body movements in vivo, is resistant to kinking or collapsing, and maintains patency, making it particularly suitable for use in dynamic environments.

3. High Transparency

• The transparent tube wall allows healthcare professionals to visually monitor the color, status, and flow of fluids (e.g., medication, blood, secretions) within the lumen in real-time, which is crucial for clinical monitoring.

4. Dual-Lumen, Integrated, Multi-Functional Design

• Integrates two independent channels (lumens) within a single tube body, enabling simultaneous multiple functions. For example, one lumen can be used for infusing medication or nutrients, while the other is used for drainage or pressure monitoring. This avoids the need to insert multiple catheters, reducing patient trauma and infection risk.

5. Outstanding Mechanical Properties

• Polyurethane material possesses high tensile strength, abrasion resistance, and tear resistance, ensuring the structural integrity and reliability of the catheter during insertion and use.

6. Chemical Resistance

• Resistant to erosion from blood, pharmaceutical fluids, lipid emulsions, etc. It is less prone to aging or performance degradation, ensuring the safety and stability of the treatment process.

Medical Applications

• Central Venous Catheters: Used for infusion, blood transfusion, central venous pressure measurement, and long-term chemotherapy. The double-lumen design allows simultaneous infusion of incompatible drugs or concurrent infusion and blood sampling.

• Swan-Ganz Catheters: Used for hemodynamic monitoring. One lumen measures pulmonary artery pressure, while the other inflates the balloon.

• Anesthesia and Analgesia: Used for epidural anesthesia and postoperative analgesia. The double-lumen design can be used for simultaneous infusion of different medications.

• Drainage Tubes: Used for postoperative drainage, such as chest drainage tubes, where the double lumen can simultaneously achieve irrigation and drainage functions.

• Nutritional Support: Used for enteral nutrition delivery, where the two lumens can be used for delivering nutritional solutions and medications separately.
