[0036] Example 1, as Figure 1 and 5 As shown,

[0037] A diverting endotracheal tube comprises a main tube 1, the head end of the main tube 1 being connected to a standard connector 2 for connecting to a ventilator, an air bag Ⅰ 3 being provided on the outer wall of the tail end of the main tube 1, and the air bag Ⅰ 3 being connected to an inflation adjustment mechanism Ⅰ 4;

[0038] The head of the main catheter 1 is provided with a steering tube section. After the main catheter 1 is placed in the trachea and / or bronchus of the human body, the steering tube section is located outside the mouth or nose of the human body, so that the steering tube section can be arbitrarily turned outside the mouth or nose of the human body.

[0039] When creating a temporary artificial breathing channel for a patient, especially a patient who cannot breathe independently, the main catheter 1 is inserted into the patient's trachea and / or bronchus, and the steering tube section is located outside the patient's mouth or nose. Then the inflation device inflates the airbag I3 through the inflation adjustment mechanism I4. The inflation device includes an inflation cylinder. The inflated airbag I3 fixes the position of the main catheter 1 in the trachea and / or bronchus. Then the standard connector 2 is connected to the ventilator. The steering tube section can be arbitrarily turned under the gravity of the ventilator pipeline, etc., to avoid ventilation obstruction caused by bending of the main catheter 1. In this technical solution, by arranging the steering tube section at the head of the main catheter 1, after the main catheter 1 is placed in the human trachea and / or bronchus, the steering tube section is located outside the human mouth or nose. The steering tube section can be arbitrarily turned outside the human mouth or nose, to avoid the part of the tracheal tube located outside the human mouth or nose from forming a bend.

[0040] As a preferred embodiment, the manner in which the steering pipe section is provided at the head of the main pipe 1 is:

[0041] The pipe section at the head of the main conduit 1 is configured as a bellows section 5 .

[0042] By setting the pipe section at the head of the main conduit 1 as the bellows section 5, the bellows section 5 has the performance of being able to turn arbitrarily and not bend after turning, so that the bellows section 5 can be turned arbitrarily under the gravity pull of the ventilator pipeline, etc., and will not bend to cause ventilation obstruction.

[0043] As a preferred embodiment, a plurality of annular reinforcement ribs 11 are symmetrically and integrally provided on the inner wall of the main conduit 1 , and the annular reinforcement ribs 11 are used to prevent the main conduit 1 from bending and forming a blockage.

[0044] The main conduit 1 is a flexible pipe, which is easily bent during use, causing ventilation obstruction and thus medical accidents; therefore, multiple annular reinforcing ribs 11 are symmetrically arranged on the inner wall of the main conduit 1. The multiple annular reinforcing ribs 11 support the inside of the main conduit 1, making the main conduit 1 flexible and the pipe wall elastic, thereby preventing the main conduit 1 from bending and forming blockage.

[0045] Example 2, as Figure 2 As shown,

[0046] A steering tracheal tube, based on the above embodiment 1, the manner in which the steering tube section is provided at the head of the main tube 1 is as follows:

[0047] An elastic metal wire 51 is provided on the wall of the head portion of the main conduit 1 , and the elastic metal wire 51 is provided in a spiral shape.

[0048] The main catheter 1 is a flexible pipe, which is easily bent during use, causing ventilation obstruction and thus medical accidents. Therefore, an elastic metal wire 51 is provided on the tube wall of the head of the main catheter 1. The elastic metal wire 51 supports the tube wall of the head of the main catheter 1, so that the tube wall of the head of the main catheter 1 cannot be blocked after bending. By arranging the elastic metal wire 51 in a spiral shape, the elastic metal wire 51 does not impose any restrictions on the bending and turning of the head of the main catheter 1, so that the head of the main catheter 1 can be turned arbitrarily and will not bend after turning.

[0049] Example 3, as Figure 3 As shown,

[0050] A steering tracheal tube, based on the above embodiment 1, the middle part of the main tube 1 is further connected with a rubber ball 6, and the rubber ball 6 is used to be placed in the human oral cavity.

[0051] After the main catheter 1 is inserted into the patient's trachea and / or bronchus, there is a risk that the main catheter 1 will fall out due to external traction; therefore, a rubber ball 6 is connected through the middle of the main catheter 1. After the main catheter 1 is inserted into the patient's trachea and / or bronchus, the rubber ball 6 is placed in the human oral cavity. The cooperation between the human oral cavity and the rubber ball 6 can prevent the main catheter 1 from falling out of the oral cavity due to external traction.

[0052] Example 4, as Figure 4 As shown,

[0053] A steering endotracheal catheter, based on the above-mentioned embodiment 1, further comprises an airbag II 7 provided on the outer wall of the middle portion of the main catheter 1, the airbag II 7 being connected to an inflation adjustment mechanism II 8. After the airbag II 7 is inflated, it is inserted into the oral cavity of a human body. After the airbag II 7 is deflated, the middle portion of the main catheter 1 can enter the nasal cavity of a human body.

[0054] In the above-mentioned embodiment 3, the rubber ball 6 is placed in the oral cavity of the human body to prevent the main catheter 1 from being pulled out of the oral cavity due to external traction. However, the way in which the rubber ball 6 is connected through the middle part of the main catheter 1 makes it possible for the main catheter 1 to be inserted into the patient's trachea and / or bronchus through the oral cavity, and its scope of use is limited. Therefore, an air bag II 7 is provided on the outer wall of the middle part of the main catheter 1, and the air bag II 7 is connected to the inflation adjustment mechanism II 8. When the main catheter 1 is inserted into the patient's trachea and / or bronchus through the oral cavity, after the main catheter 1 is inserted into the patient's trachea and / or bronchus through the oral cavity, the inflation device inflates the air bag II 7 through the inflation adjustment mechanism II 8. The inflated air bag II 7 is located in the patient's oral cavity, preventing the main catheter 1 from being pulled out of the oral cavity due to external traction. When the main catheter 1 is inserted into the patient's trachea and / or bronchus through the nasal cavity, the air bag II 7 is deflated. The deflated air bag II 7 can enter the patient's nasal cavity, thereby ensuring applicability.

[0055] As a preferred embodiment, the inflation adjustment mechanism II8 has the same structure as the inflation adjustment mechanism I4, and the inflation adjustment mechanism I4 includes:

[0056] An inflation line 41, one end of which is connected to the airbag I3, and the other end of which is connected to one end of an airbag pressure sensing device 42;

[0057] A one-way inflation valve 43 is connected to the other end of the airbag pressure sensing device 42 .

[0058] When inflating the airbag I3, the inflation device is connected to the one-way inflation valve 43. The gas injected by the inflation device enters the airbag I3 after passing through the one-way inflation valve 43, the airbag pressure sensing device 42, and the inflation pipeline 41. The one-way inflation valve 43 forms a one-way channel to prevent the gas injected by the inflation device from flowing back and leaking. The airbag pressure sensing device 42 feeds back the inflation status of the airbag I3 to prevent the airbag I3 from being over-inflated or under-inflated.

[0059] Example 5, as Figure 6-7 As shown,

[0060] A steering endotracheal tube, based on the above-mentioned embodiment 1, further includes a suction tube 9, which is arranged in the main duct 1, the tail end of the suction tube 9 is sealed, and the head end of the suction tube 9 is set through the main duct 1. A plurality of suction holes 91 are symmetrically opened on the suction tube 9, and the suction holes 91 are located in the main duct 1.

[0061] When there is sputum in the patient's respiratory tract, it will cause the main catheter 1 to be blocked. In order to suck out the sputum in the respiratory tract in time, it is necessary to turn off the ventilator connected to the main catheter 1 and insert a sputum suction tube 9 to suction the sputum. The sputum suction operation affects the normal oxygen supply to the patient and poses a safety hazard. Therefore, a sputum suction tube 9 is set in the main catheter 1. When the sputum suction operation is performed, the head end of the sputum suction tube 9 is connected to the sputum suction device. The sputum suction device generates negative pressure, so that the sputum entering the main catheter 1 enters the sputum suction tube 9 through multiple sputum suction holes 91, and the sputum then enters the sputum suction device through the sputum suction tube 9. The tail end of the sputum suction tube 9 is sealed to ensure the adsorption strength of the sputum suction holes 91 on the sputum. While the sputum suction tube 9 is suctioning, the ventilator continues to supply oxygen to the patient normally through the main catheter 1, thereby avoiding safety hazards.

[0062] As a preferred embodiment, the sputum suction tube 9 is fixedly connected to the main conduit 1 in a spiral shape.

[0063] By fixing the suction tube 9 in a spiral shape in the main catheter 1, multiple suction holes 91 are evenly distributed in the main catheter 1. The main catheter 1 can be placed in any position in the patient's trachea and / or bronchus for suctioning.

[0064] As a preferred embodiment, the head end of the sputum suction tube 9 is connected with a transfer tube 92 , and the transfer tube 92 is used to connect to a sputum suction device. The transfer tube 92 is also detachably connected with a sealing plug 93 .

[0065] By connecting the adapter tube 92 through the head end of the suction tube 9, the suction tube 9 is easily connected to the suction device, and the sealing plug 93 can seal the head end of the suction tube 9 when suction is not being performed, thereby preventing leakage from the head end of the suction tube 9 when suction is not being performed.

[0066] The above description is merely a preferred embodiment of the utility model and is not intended to limit the technical solution of the utility model. Those skilled in the art will readily appreciate that the utility model is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the technical solution of the utility model shall be included within the scope of protection of the utility model.
