Medical tube

Abstract

Abstract Disclosed herein is a medical tube (1) which comprises a surface-treated inner tube (2) of fluoroplastic, a metal wire (3) spirally wound round the inner tube (2), and an outer covering (4) of polyurethane placed outside the spirally wound metal wire (3), said outer covering (4) being bonded to and integral with the inner tube (2) through the interstices of the spirally wound metal wire (3). It does not collapse easily when bent, because the spirally wound metal wire (3) reinforces the tube wall. It can be bent with a smaller bending radius than the conventional one. It can be made in smaller diameter because it is possible to reduce the wall thickness without any fear of its collapsing. These advantages contribute to reducing the diameter of the inserting part of an endoscope.
