Product Details

This medical-grade TPU flared tube, officially known as the stress dispersion tube (also called stress relief tube or stress buffer tube, in English: Stress Dispersion/Relief Tube), is a core semi-finished component of medical catheter devices. Its primary function is to disperse the stress at the bend of the catheter, preventing the tube from kinking or breaking at the joint. Additionally, the flared structure enhances the bonding or welding strength with the joint, ensuring the stability and unobstructed flow of the pipeline. National Medical Products Administration.

The TPU stress diffusion tube is mainly applied in the following medical device products:

Core mainstream application: Interventional catheter devices

This is the primary application scenario for this type of expansion tube. It is a standard component of this kind of device. In the compliant interventional catheter products approved by the National Medical Products Administration, the stress diffusion tube is clearly listed as a core component.
