The invention relates to a novel trachea intubation tube. The novel trachea intubation tube aims at solving the defects that an existing trachea intubation tube is easy to block after an operation, a glottis is easy to injure when the existing trachea intubation tube is replaced, laryngeal edema is easy caused, and finally intubation difficultly is increased, and even intubation fails, and furthermore intubation tube indwelling time is long, and pneumonia related to a respirator catheter is high in occurrence rate. For solving the above technical problems, the novel trachea intubation tube comprises three portions of a metal sleeve, a disposable plastic inner sleeve and a disposable plastic outer sleeve. The novel trachea intubation tube is characterized by being supported through the metal sleeve, and used in combination with air sacs on the plastic inner sleeve and the plastic outer sleeve, sealing the inner sleeve and the outer sleeve with peripheral structures, not only achieving the purpose of building an artificial airway of a common trachea intubation tube, but also simultaneously achieving the purposes that the inner sleeve and the outer sleeve can be conveniently replaced at any moment, avoiding tube blocking, reducing the occurrence rate of the pneumonia related to the respirator catheter, and preventing the risk that the glottis and a throat are injured due to repeated tube insertion from occurring, and furthermore has the advantages of being environmentally friendly, and low in use cost due to the fact the metal sleeve can be repeatedly disinfected and used.
