[0045] Referring to Figure 1 , Figure 2 In some embodiments of the present application, the base section 100 is branched into a first branch pipe 130 and a second branch pipe 140 at one end away from the pilot section 200, the oxygen channel 310 and the working channel 320 pass through the first branch pipe 130 and the second branch pipe 140 respectively, the first branch pipe 130 and the second branch pipe 140 are both connected with corrugated hoses 150, the corrugated hoses 150 are suitable for stretching and / or bending, and the docking of the ventilation and oxygen supply equipment is greatly facilitated, and the suction sputum tube and other tools are conveniently placed in the working channel 320.

[0046] Referring to Figure 1 , Figure 2 The working channel 320 passes through the second branch pipe 140, and the corrugated hose 150 connected with the second branch pipe 140 is provided with a rotary valve 151.

[0047] Referring to Figures 1 to 4In some embodiments of this invention, an air cuff 400 is also included. A pilot section 200 passes through the air cuff 400, and both ends of the air cuff 400 are sealed around the outer periphery of the pilot section 200. The multifunctional endotracheal intubation catheter is provided with an air regulating channel 330. One end of the air regulating channel 330 is connected to the air cuff 400, and the other end is suitable for inflation and deflation and is connected to a shut-off valve 510. In the application of this invention, the air cuff 400 inflates to block the trachea at the patient's glottis, fixing the pilot section of the catheter and facilitating stable ventilation and oxygen supply through the oxygen channel 310.

[0048] In the actual manufacturing process of this utility model, the core is inserted into the working channel and / or oxygen channel to support the conduit. The middle of the protective airbag 400 is isolated by the mold. The two ends of the airbag 400 are thermoplastically shrunken onto the outer wall of the conduit. The two ends of the airbag 400 are further fused to the outer wall of the conduit. The processing of the buffer bladder 520 and the air-closing valve 510 is similar.

[0049] In part of the design of this utility model, the air-closing valve 510 is essentially a ball valve, similar to the knob valve 151; opening the ball valve allows the airbag 400 to be inflated and deflated.

[0050] In the above methods, when inflating, after connecting the air pump, the ball valve still needs to be operated; when deflating, only the air-closing valve 510 is opened, which is a rough deflation, making it difficult to control the air pressure of the airbag 400. (Refer to...) Figures 1 to 4 In some embodiments of this invention, the air-closing valve 510 is a first one-way valve inserted into the air pump. The valve core of the first one-way valve is adapted to be closed under normal conditions, and the valve core is adapted to be pushed open by the needle of the air pump. For the one-way valve, it can be understood that when air is pumped into the one-way valve, the inflation gas can push open the valve core, i.e., the spring is compressed, and the valve core opens. In this invention, the inflation port of the first one-way valve is adapted for insertion of the needle of the air pump, and the valve core of the first one-way valve is adapted to be pushed open by the needle, facilitating the air pump to draw air from the air bag 400 and the air regulating channel 330. During inflation and deflation, the resistance felt when pushing the air pump is used to determine whether the air pressure in the air bag 400 is reasonable, avoiding excessive compression of the patient's trachea / airway by the air bag 400; when the air resistance feels appropriate, the pushing and pulling of the air pump piston can be stopped, the air pump is pulled away from the first one-way valve, and the first one-way valve automatically closes. In a preferred embodiment, the air pump is a medical syringe.

[0051] Reference Figures 1 to 4 In some embodiments of this utility model, a buffer bladder 520 is also included. The inflation / deflation port of the air regulating channel 330 is connected to one end of the buffer bladder 520. A first one-way valve is provided at the other end of the buffer bladder 520, and a second one-way valve 530 is provided at the other end of the buffer bladder 520. The buffer bladder 520 is suitable for replenishing air to the airbag 400, reducing the frequent removal of the air inflator. When the buffer bladder 520 is squeezed to inflate the airbag 400, the degree of inflation (air pressure) of the airbag 400 is judged by the resistance felt when squeezing.

[0052] Referring to Figure 4 In some embodiments of the utility model, still include the buffer bag 520, the inflation and deflation port of the air adjusting channel 330 is communicated with one end of the buffer bag 520, the other end of the buffer bag 520 is provided with the first check valve, and the inflation of the buffer bag 520 is suitable for indicating that the outer wall of the air bag 400 is inflated to the inner wall (i.e. the tracheal wall of the patient) of the target tube. After the inflation of the buffer bag 520, further air supplement is carried out, and the inflation degree (air pressure) of the air bag 400 is judged by the resistance feeling.

It can be understood that the groove bottom of the air adjusting groove 610 is used for the third branch pipe 160 to lie down, so the air adjusting section 611b extends along the axial direction of the groove bottom of the air adjusting groove 610. According to the volume of the air bag 400, the length of the air adjusting section 611b is set.

[0054] Referring to Figure 4 、 Figure 5 The operation process of the utility model includes that the air adjusting roller 620 loosens the third branch pipe 160, i.e. the air adjusting roller 620 is located at the opening and closing control section 611a and slightly extrudes or does not extrude the third branch pipe 160, then the air bag 400 and the buffer bag 520 are supplemented with air by the air pump, the air pump is pulled away after the air pump completes the inflation, and the first check valve is automatically closed. After a certain period of time of inflation use, when it is found that the buffer bag 520 starts to shrink, it is determined that the air bag 400 also shrinks, the air bag 400 is supplemented with air through the buffer bag 520, then the air adjusting roller 620 is closed, i.e. the air adjusting roller 620 is driven to the end of the opening and closing control section 611a (the middle part of the sliding groove 611), or even is completely located at the air adjusting section 611b, the air adjusting roller 620 of the air adjusting section 611b is slightly pushed and extruded at random, the inflation degree (air pressure) of the air bag 400 is judged by the pushing resistance of the air adjusting roller 620, and the gas of the third branch pipe 160 is also extruded to the air bag 400.
