Extruded Medical Catheter with PVC Double Channel Tubing for Medical Supply

Introduction

Material：PVC（Polyvinyl Chloride）

PVC material compatibility and design advantages

Medical-grade PVC (phthalate-free plasticizers) exhibits excellent biocompatibility and resistance to disinfectants such as alcohol and peroxide, making it suitable for single-use or short-term reuse applications.

High molding precision allows for stable cavity diameter combinations from 0.3mm to 8mm, meeting the full range of specifications from newborns (4Fr) to adults (21Fr).

Clinical value of dual-row structure

Integrated management: The parallel molding of two tubes allows for controllable connection force, avoids tangling of multiple tubes, improves operational efficiency, and reduces nursing errors.Functional Separation: Completely avoids drug incompatibilities and fluid cross-contamination, especially suitable for critical care multi-drug combination therapy scenarios.

Customizable Expansion: Can be customized with the addition of imaging lines, scale markings, and anti-kink design, adaptable to different departmental equipment interfaces (Luer connectors, pagoda connectors, etc.).

Performance Advantages and Medical Applications of Disposable PVC Double Channel Catheters

PVC dual-row catheters (also known as main and auxiliary dual-lumen parallel catheters) with different orifice sizes have the core value of independent dual lumens and graded flow rates, which are suitable for the clinical needs of simultaneous "high flow delivery/coarse fluid treatment" and "precise drug administration/delicate operation", and have clear applications in multiple departments such as critical care, surgery, gastroenterology, and respiratory.

Core application scenarios and typical uses of PVC Double-channel Tube

Dual-lumen central venous catheter (CVC): The large-diameter main lumen (14G-16G) is used for rapid fluid resuscitation, blood transfusion, infusion of total parenteral nutrition (TPN) and other viscous fluids, and also for measuring central venous pressure; the small-diameter auxiliary lumen is used for routine infusion, infusion of vasoactive drugs or antibiotics.

Dual-lumen peripherally inserted central catheter (PICC): Suitable for patients undergoing long-term treatment, the main lumen allows for rapid fluid resuscitation, while the auxiliary lumen allows for precise infusion of chemotherapy drugs or vasoactive drugs, reducing the risk of repeated punctures and drug interactions.

Abdominal/wound flushing and suction tube: The large-diameter main lumen is connected to negative pressure suction to efficiently drain accumulated fluid, pus, and necrotic tissue; the small-diameter abdominal cavity is continuously infused with physiological saline and antibiotic solutions, achieving "flushing and suctioning simultaneously" to reduce the risk of tube blockage and infection.

Orthopedic surgical drainage: such as joint replacement and fracture repair, draining bloody exudate from the main cavity and administering local medications (such as analgesics and antibiotics) to the auxiliary cavity to accelerate wound healing.

Laparoscopic surgery tubing: As an irrigation device component, the main cavity rapidly returns irrigation fluid, while the auxiliary cavity precisely injects irrigation medium, improving the clarity of the surgical field.

Double-lumen gastric tube (flushing/drainage type): The large-diameter main lumen is used for gastrointestinal decompression, continuously aspirating gastric juice and gas to prevent gastric distension; the small-diameter auxiliary lumen can be used to inject prokinetic drugs, perform gastrointestinal flushing, or provide enteral nutrition while decompressing.

The anesthesia machine is equipped with a dual-row tubing system: the main chamber delivers anesthetic gas, while the abdominal chamber is used for respiratory parameter monitoring or emergency oxygen supply. Made of PVC, it is resistant to disinfectants, easy to clean, and suitable for high-frequency use in operating rooms.

Dental/cosmetic equipment tubing: Main cavity delivers rinsing fluid or treatment media, abdominal cavity aspirates waste fluid, orifice size varies to match "delivery-recovery" flow requirements, PVC anti-kink and lightweight, compatible with dental chairs and other mobile devices.
