AI Technical Summary
The existing oxygen inhalation catheters for intubated patients are prone to loosening after repeated adjustments, leading to displacement and slippage of the catheter, which affects the effectiveness of use.
The adjustment assembly, consisting of an inner shrinking cylinder and an outer adjusting cylinder, is secured by threaded connections and adhesive tape to ensure stable insertion of the small-diameter connecting tube into the endotracheal tube, preventing displacement and slippage.
This design achieves stable fixation of the oxygen delivery tube on the endotracheal cannula, preventing displacement and slippage during use and ensuring the stability of the oxygen delivery effect.

Abstract
Claims
1. An oxygen inhalation catheter for a patient with endotracheal intubation, comprising a catheter body (100), with a first connection port (110) for connecting to an oxygen source and a second connection port (120) for connecting to an endotracheal tube at both ends, wherein a small-diameter connecting tube (200) is connected to the front end of the second connection port (120), the diameter of the small-diameter connecting tube (200) being smaller than the diameter of the catheter body (100), characterized in that, The small-diameter connecting pipe (200) is provided with an adjusting assembly (300), which includes an inner shrink cylinder (310), an outer adjusting cylinder (320), and adhesive tape (330). The inner shrink cylinder (310) is slidably sleeved on the small-diameter connecting pipe (200), and its outer side has an external thread (313) on one end and an anti-detachment protrusion ring (311) and several adjusting slots (312) on the other end. The adjusting slot (312) is arranged circumferentially along the inner shrinking cylinder (310) and is parallel to the axial direction of the inner shrinking cylinder (310) and disconnects the anti-detachment protrusion ring (311); the outer adjusting cylinder (320) is sleeved on the inner shrinking cylinder (310), the inner diameter of one end of which is continuously reduced, and the inner side of the other end is provided with an internal thread that matches the external thread (313); one end of the adhesive tape (330) is connected to the outer side wall of the outer adjusting cylinder (320).
2. The oxygen catheter of claim 1, wherein: The adhesive tape (330) has two strips.
3. The oxygen delivery catheter according to claim 2, characterized in that: The outer adjusting cylinder (320) has connecting ears (321) on both sides. The connecting ears (321) have through holes. One end of the adhesive tape (330) passes through the through hole and is fixedly connected to the connecting ears (321).
4. The oxygen catheter for a trachea cannulated patient according to claim 1, characterized by: The plurality of adjusting slits (312) are evenly distributed along the circumference of the inner contraction cylinder (310).
5. The oxygen catheter for a trachea cannulated patient according to claim 1, characterized by: The outer wall of the outer adjusting cylinder (320) is provided with anti-slip texture.
