本发明涉及一种导管，所述导管包括在导管插入过程中由内向外翻折的导管的管。所述导管的管包括：多个纵向突起，所述纵向突起从所述导管的管的第一端延伸通过所述导管的管的至少一部分，并形成相对于所述导管的管的纵向轴线呈0度至45度的角度且朝向径向向内；和用于在从所述导管的管的第一端由内向外翻折所述导管的管时扩张所述导管的管的圆周的部分。所述纵向突起确保了所述导管的管的轴向加强，这防止了所述管在轴向力和折叠部的阻力、以及翻折部分和所述管的相应的下侧部分之间的摩擦阻力的作用下塌陷和弯曲。扩张部分扩张所述导管的管的位于翻折区域中的圆周，从而减小了折叠部的阻力以及翻折部分与所述管的相应的下侧部分之间的摩擦阻力。

The present invention relates to a catheter, which comprises a catheter tube everting inside-out during the process of catheterization. A catheter tube comprises a plurality of longitudinal protrusions extending from the first end of the catheter tube through at least a portion of the catheter tube, and forming an angle of 0 degrees to 45 degrees with respect to the longitudinal axis of the catheter tube and facing radially inwards, and means for dilating a circumference of the catheter tube upon everting the catheter tube inside-out from the first end of the catheter tube. The longitudinal protrusions ensure the axial reinforcement of the catheter tube, which prevents the tube from collapsing and bending under the axial force and the resistance of the fold and of the friction between theeverted portion and the corresponding underlying portion of the tube. The dilating means dilate the circumference of the catheter tube in the everted region, thus reducing the resistance of the fold and of the friction between the everted portion and the corresponding underlying portion of the tube.
