Permanent medical tube for bile duct, pancreatic fluids etc

The tube comprises a part (1) which has thermoplastic resin at its interior with a controlled surface roughness controlled. The surface roughness can be adjusted and is expressed by a maximum profiled height (Ry), this height being 0,5 mu m or less. This prevents the adhesion of fluid bacteria and o...

Summary:The tube comprises a part (1) which has thermoplastic resin at its interior with a controlled surface roughness controlled. The surface roughness can be adjusted and is expressed by a maximum profiled height (Ry), this height being 0,5 mu m or less. This prevents the adhesion of fluid bacteria and other materials to the tube inner surface. The maximum profile height (Ry) is a value obtained by intersecting one reference length only in a direction from its centre line from a surface roughness-curve, and by measuring the space between a top line of the cut area and a bottom line in a direction where the roughness-curved increases in length.
