The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the endotracheal tube of the present embodiment includes a main catheter 1, a humidifying tube 2, a suction tube 3 and a bite block, wherein a first channel 5 and a second channel 6 are arranged inside a side wall of the main catheter 1 along a length direction of the main catheter 1, outlets of the first channel 5 and the second channel 6 are both located at an outlet end of the main catheter 1, the humidifying tube 2 is communicated with the first channel 5, and the suction tube 3 is communicated with the second channel 6; the main catheter 1 can be externally connected with an oxygen supply device to continuously supply oxygen to the trachea of a patient, and the humidifying catheter 2 can be externally connected with an infusion device to continuously input humidifying liquid and can also be injected with humidifying liquid or medicines at any time; the suction tube 3 can be externally connected with a negative pressure suction apparatus, so that sputum and regurgitated gastric contents between the outer wall of the trachea cannula and the inner wall of the airway of the patient can be sucked conveniently.

The bite-block is including the lasso 9 of cover on main catheter 1, and the lasso 9 overcoat is equipped with silica gel pad 10, and 9 inner walls of lasso are equipped with a plurality of flexible sand grips 11 along the axial of lasso 9. Lasso 9 is made by the stereoplasm material, overlaps lasso 9 on main catheter 1, and flexible sand grip 11 is extrudeed to fix lasso 9 on main catheter 1, lasso 9 direct contact oral cavity, through the difficult damage oral cavity of soft silica gel pad 10 contact oral cavity.

Because the fixed time of lasso 9 is realized by the extrusion through flexible sand grip 11, can not remove easily, but when needs remove the bite-block, can exert great external force and remove lasso 9 to make the bite-block also can reciprocate, main duct 1 stretches into different depths when being applicable to different patients' trachea cannula, can adjust the height of bite-block so that clean and nursing simultaneously.

The exit end of main duct 1 is the silica gel material, prevents to damage the air flue.

The silicone pad 10 is provided with two fixing holes 12 for the adhesive tape to pass through. The adhesive tape can be wound on the silica gel pad 10 to limit the bite block after passing through the fixing hole 12.

The silica gel pad 10 is connected with a hydrocolloid dressing 14 through a fixing buckle 13. The hydrocolloid dressing 14 is easy to fix, convenient to use, has the ability of absorbing seepage liquid, and hydrocolloid dressing 14 can contact with patient's skin for the position of bite-block is relatively fixed with the human body.

An end cover 15 is detachably covered on the inlet end of the main guide pipe 1, and a filter screen is arranged in the main guide pipe 1. Before the main duct 1 is used, the end cap 15 covers the inlet end of the duct 1 to prevent impurities from entering. When the main catheter 1 is used, the filter screen can filter out impurities in oxygen and prevent the impurities from entering the trachea of a patient.

The main catheter 1 is provided with an air bag 8, a third channel 7 communicated with the air bag 8 is further arranged inside the side wall of the main catheter 1, and the third channel 7 is connected with an air bag tube 4. The air bag tube 4 can inflate the air bag 8 to expand the air bag 8, so that the air bag 8 is filled in the trachea of the patient to fix the main catheter 1.

The inner wall of one section of main duct 1 near the exit end is equipped with the spiral steel wire, and the spiral steel wire makes main duct 1 be difficult to sink with main duct 1 inner wall zonulae occludens.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
