The invention relates to a tracheal catheter, in particular to a multi-layer co-extrusion controllable stripping tracheal catheter, which belongs to the technical field of medical devices. According to the technical solution provided by the present invention, the multi-layer co-extrusion controllable peelable endotracheal tube includes a main body of the endotracheal tube; the inner wall of the main body of the endotracheal tube is provided with several layers of mantles that can be peeled off from each other. The present invention arranges several layers of mantle in the endotracheal tube body, and by peeling off the mantle in the endotracheal tube body, the secretion adhering to the innermost mantle of the endotracheal tube can be removed in time to keep the lumen of the endotracheal tube unobstructed. It is compact, easy to use, can greatly and effectively prolong the retention time of endotracheal tube intubation, reduces the probability of tracheotomy operation, has wide application range, low cost, and is safe and reliable.
