Title: METHOD FOR MANUFACTURING ENDOTRACHEAL INTUBATION TUBE AND ENDOTRACHEAL INTUBATION TUBE
Abstract:
Disclosed is a method for manufacturing an endotracheal intubation tube, comprising the following steps: manufacturing an integral mould (200) used for manufacturing an airbag (20), wherein an inner cavity (202) is arranged inside the mould (200); filling the mould (200) with a PVC slurry; pouring out the PVC slurry, and reserving the PVC slurry left on the inner wall of the mould (200); passing a guide tube (500) through the mould (200); sleeving the guide tube (500) with a tube body (10) and passing the tube body through the mould (200); withdrawing the guide tube (500); respectively inserting a first core (300) and a second core (400) into the tube body (10) and docking the cores, and laminating the tube body (10) to the inner wall at the end of the inner cavity (202); rotating the mould (200) and heating it; and exhausting the air inside the airbag (20) and demoulding, wherein the docking position of the first core (300) and the second core (400) is at the middle of the inner cavity (202). Also provided is an endotracheal intubation tube (100) manufactured by the above-mentioned method for manufacturing an endotracheal intubation tube. Since heating and rotating the mould (200) are carried out at the same time, the PVC slurry on the inner wall of the mould (200) may not be aggregated during the heating and maturing process, and the PVC slurry on the inner wall of the complete mould (200) is made to be homogeneous. Accordingly, the wall thickness of the manufactured airbag (20) is relatively homogeneous and there are no steps on the two ends of the airbag (20).
