Product Description

**6.53.5+3.0 1.6mm Dual Channel Medical Tubing**

Fully Manufactured in ISO13485 Certified Cleanroom | Non-Sterile | PE Bag Packaging

Product Overview

Material：PVC（Polyvinyl Chloride）

This custom medical PVC double channel negative pressure tubing is extruded from premium medical-grade PVC material. The semi-transparent blue tube body allows clear observation of fluid flow during clinical operations. It adopts an integrated double-row dual-lumen structure with standard dimensions: main lumen OD 6.5mm / ID 3.5mm, secondary lumen OD 3.0mm / ID 1.6mm. It is specially engineered for negative pressure drainage and multi-channel fluid transmission, and perfectly compatible with various drainage devices and interventional medical equipment.

The entire production process is completed in an ISO13485 certified cleanroom, where particulate contamination and bioburden are strictly controlled. The product is supplied in non-sterile condition and sealed with medical-grade PE bags.

Clinical value of dual-channel 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.).

Core Advantages & Features

1. Isolated Dual-channel Structure for Stable Negative Pressure Operation

Made by precision one-piece co-extrusion technology, the two independent lumens avoid fluid cross-flow completely. The main channel undertakes negative pressure drainage and fluid delivery, while the auxiliary lumen can be used for ventilation, irrigation and real-time monitoring. With tight dimensional tolerance, the tubing fits tightly with matching medical components and effectively prevents liquid leakage.

2. Reliable Medical-Grade PVC Material

The raw material complies with medical industry standards, featuring outstanding flexibility, kink resistance and chemical stability. The tube is easy to bend without blockage during use. The semi-transparent design enables medical staff to check fluid status intuitively, improving operational safety and efficiency.

3. Strict ISO13485 Cleanroom Production

From raw material feeding, extrusion molding to final packaging, all procedures are carried out in an ISO13485 compliant cleanroom. We implement strict environmental control to reduce particulate matter and microbial pollution, ensuring stable product quality and consistent performance among batches.

4. Non-Sterile Supply for Higher Flexibility

Delivered in non-sterile state, the tubing can be matched with customers’ existing sterilization processes. It helps clients save extra sterilization costs and adapt to diversified terminal product production plans.

5. Comprehensive Customization Support

We provide one-stop customized services to meet diverse demands:

Custom outer diameter, inner diameter, wall thickness and multi-channel structures
Custom tube color, transparency, radiopaque lines and scale printing
Deep processing: fixed-length cutting, hole punching, flaring, heat shrinking and connector welding
Custom packaging: anti-static bags, reels, trays and personalized labels

Production & Quality Control

We follow the ISO13485 medical device quality management system and implement full-process quality supervision:

Raw Material Inspection: All medical PVC materials are sourced from qualified suppliers. Material certificates and biocompatibility reports are provided for every batch to guarantee raw material safety.
Cleanroom Management: Regular testing on indoor particles and microorganisms is conducted. All operators wear professional protective suits to maintain a high-standard production environment.
In-Process Monitoring: Key parameters including outer diameter, inner diameter, wall thickness and ovality are monitored in real time during extrusion. Sampling inspection is performed every hour to keep dimensions within tolerance.
100% Final Inspection: All finished products are checked on appearance, size and cleanliness before delivery to reject defective goods.
Complete Batch Traceability: A full traceability system is established. Each batch of products can track raw material sources, production records and inspection reports, fully meeting medical device regulatory requirements.

Packaging & Delivery

Standard Packaging: Each product or group of products is sealed in independent PE bags, then packed into outer cartons. This packaging method effectively prevents contamination, extrusion and damage during transportation and keeps the tubing clean.
Custom Packaging: Anti-static bags, dedicated reels, trays and customized labels are available on request.
Lead Time: Standard products are in stock for prompt delivery. For customized orders, the lead time is 25-30 working days, subject to final order confirmation.
Export Support: We are experienced in international trade and can provide complete export documents and customs clearance assistance for global B2B clients.
