PVC Double Channel Tube

PVC Transparent Double Channel Plastic Medical Tube for Disposable Medical Consumables

Introduction

Material：PVC（Polyvinyl Chloride）

Performance Advantages and Medical Applications of Medical Clear PVC Double-Lumen Tubing 

Performance Advantages

1. Excellent Clarity and Visibility

• The highly transparent tube wall allows medical staff to clearly and simultaneously observe the flow, color, and presence of bubbles or precipitates in the two independent channels.

2. Integrated Dual-Lumen Design

• Integrates two separate fluid paths within a common sheath. This compact structure simplifies tubing layout, avoids the tangling of multiple single tubes, and facilitates management and use.

3. Superior Flexibility and Durability

• PVC material offers good flexibility and elasticity, making the tubing easy to position and secure in clinical use. It also provides certain crush resistance, preventing collapse and ensuring fluid patency.

4. Good Biocompatibility and Safety

• Medical-grade PVC compound complies with relevant biocompatibility standards (e.g., ISO 10993) and is typically latex-free, reducing the risk of allergies and ensuring safety upon contact with the human body.

5. High Cost-Effectiveness

• PVC raw materials are relatively low-cost, and the production process is mature, making this type of tubing highly cost-effective. It is suitable for single-use, effectively preventing cross-contamination.

6. Ease of Processing and Sealing

• Can be easily manufactured via extrusion processes. End connectors (e.g., Luer connectors) can be securely bonded or welded, ensuring the sealing integrity and reliability of each channel.

Medical Applications

• Intravenous Infusion and Blood Transfusion: Especially suitable for situations requiring simultaneous infusion of different fluids (e.g., nutritional solutions and antibiotics) that must not be mixed. One lumen can be for the primary drug, while the other can be for auxiliary fluids or connection to pressure monitoring devices.

• Blood Purification and Dialysis: Used in hemodialysis machines, Continuous Renal Replacement Therapy (CRRT) systems, etc., serving as blood lines and replacement fluid lines.

• Anesthesia and Respiration: Used in anesthesia machine breathing circuits, where one lumen delivers fresh gas, and the other can be used for pressure monitoring or return gas.

• Pressure Monitoring: In arterial or venous pressure monitoring, one lumen is used for fluid infusion to keep the line patent, while the other is connected directly to the pressure transducer.

• Interventional Angiography: During interventional procedures like angiography, it is used for simultaneous delivery of contrast media and saline or other medications.
