How to Select a Customized Manufacturer for Medical Multi-chamber TubesHow to Select a Customized Manufacturer for Medical Multi-Lumen Tubes

With the rapid development of minimally invasive medical and interventional diagnostic technologies, the demand for customized multi-lumen medical catheters, as core consumables, continues to rise. Standardized tubing of a single specification is no longer sufficient to cover the functional designs of different devices. Customized multi-lumen catheters with independent lumens, and special materials have become a key support for medical device R&D and mass production. Kunshan Bova Plastics has been deeply involved in the field of precision medical catheters for over ten years, providing full-process customized multi-lumen catheter services to help medical companies achieve product differentiation.

Customized Multi-lumen Tubes for Medical Use: A Core Need for the Refined Development of Medical Devices

Medical multi-lumen tubing integrates multiple independent lumens within a single tube, simultaneously enabling multiple functions such as drug infusion, guidewire passage, pressure monitoring, and fluid drainage. It is widely used in central venous catheters, ERCP, drainage devices, and interventional procedures. Different clinical scenarios have significantly different requirements for the number of lumens, cross-sectional shape, wall thickness tolerances, and material properties. Standardized products often cannot meet end-user design needs, making customized production the mainstream solution in the industry.

The core advantages of Bova Multi-Cavity Plastic Tube Customization

Full material coverage, adaptable to different clinical performance requirements

Bova supports the extrusion production of various medical-grade raw materials such as TPU, PE, PP, PVC, Pebax, PA, PC, PET, and PLA. It can match corresponding materials according to the product's requirements for hardness, elasticity, biocompatibility, and chemical resistance, while also taking into account the selection of high-end medical-grade materials such as non-phthalic medical PVC and polyether-type TPU, to meet different device registration and clinical use standards.

Precision extrusion process, controllable dimensional tolerances

Bova is equipped with a high-precision extrusion production line and online testing equipment. The outer diameter tolerance of multi-cavity tubes can be controlled within ±0.02mm, and the thinnest wall thickness can reach below 0.07mm. The inner wall of the cavity is smooth and burr-free, and the roundness of the circular cavity is stable. It can produce dual-cavity, triple-cavity, and multi-cavity structures, and supports various cavity cross-section designs such as circular, crescent-shaped, and irregular shapes to adapt to complex fluid and mechanical performance requirements.

Full-chain post-processing services, one-stop delivery

In addition to basic extrusion molding, our company also provides complete post-processing value-added services, covering processes such as hot stamping, sealing, flaring, punching, necking, ink printing, laser marking, welding, bending and shaping, beveling, and strip cutting. Customers can complete the entire process from pipe extrusion to finished product deep processing without having to deal with multiple suppliers, effectively shortening the R&D and production cycle.

Multi-lumen tube customization service process and application scenarios

After the client provides drawings or samples, the technical team quickly completes material selection and process evaluation, and provides a customized solution. After confirming the size and performance through small-batch trial production, large-scale mass production can be achieved. The products are widely used in multiple medical fields such as drainage catheters, central venous catheters, interventional sheaths, digestive endoscopy consumables, and urological devices, supporting full-cycle cooperation from R&D prototyping to mass production.
