SURFACE TREATMENT DEVICE OF FLEXIBLE TUBE, SURFACE TREATMENT METHOD OF FLEXIBLE TUBE, AND SURFACE-TREATED FLEXIBLE TUBE

摘要

PROBLEM TO BE SOLVED: To provide a surface treatment device and a surface treatment method of a flexible tube which can provide a flexible tube at low cost which is easy to handle, is excellent in terms of hygiene, and is suitable even for medical treatment by modifying a surface of the flexible tube which is adhesive, of which an outer circumferential surface is not slippery, and on which dust is likely to adhere, and provide the surface-treated flexible tube.SOLUTION: A surface treatment device of a flexible tube includes: a guide bar 2 which is inserted into a hollow part of a flexible tube and linearly holds the flexible tube; a guide bar rotation mechanism 3 which rotates the guide bar 2; and a surface treatment tool moving mechanism which moves a surface treatment tool along the flexible tube held by the guide bar 2. The flexible tube is formed by forming a fine rough surface layer on a surface of the flexible tube, forming a lubricant coating layer on a surface of the rough surface layer, and forming a durable coating layer on a surface of the lubricant coating layer by a surface treatment method of the flexible tube using the surface treatment device.SELECTED DRAWING: Figure 2
