We report a case of Parker Flex-Tip endotracheal tube obstruction caused by its tip bending outward against the tube lumen. The Parker Flex-Tip tube tip is designed to bend inward to prevent damage to airway structures during intubation. However, when its tip is bent outward, the tube aperture is distorted, shifts against the tracheal wall, and is occluded. Moreover, the cross-sectional area of the openings on the side of the endotracheal tube, the "Murphy's eyes" which are ellipses, decrease because the openings are pulled parallel to their long axis. Outward bending of the tip can obstruct the tube.
我们报告了一例 Parker Flex-Tip 气管内导管尖端向外弯曲导致管腔阻塞的病例。Parker Flex-Tip 气管内导管尖端的设计是向内弯曲，以防止在插管过程中损伤气道结构。然而，当尖端向外弯曲时，管腔孔径变形，与气管壁移位并阻塞。此外，气管内导管侧面的开口，即“墨菲眼”（椭圆形）的横截面积减小，因为开口沿其长轴被平行牵拉。尖端向外弯曲会阻塞导管。
