A first channel 11, a second channel 12 and a third channel are formed in the endotracheal cannula 1. The first channel 11, the second channel 12 and the third channel are not connected, and the third channel extends from one end to the other end of the endotracheal cannula 1; the first cuff 2 is sleeved on the periphery of the endotracheal cannula 1, the first cuff 2 is connected to the outlet of the first channel 11, and the outer diameter of the first cuff 2 is larger than the outer diameter of the endotracheal cannula 1; the second cuff 3 is sleeved on the periphery of the endotracheal cannula 1 and arranged adjacent to the first cuff 2, the second cuff 3 is connected to the outlet of the second channel 12, and the outer diameter of the second cuff 3 is larger than the outer diameter of the endotracheal cannula 1; the first inflatable component 4 is connected to the inlet of the first channel 11; the second inflatable component 5 is connected to the inlet of the second channel 12.

[0067] Specifically, an embodiment of the present invention provides an endotracheal intubation device, comprising an endotracheal cannula 1, a first cuff 2, a second cuff 3, a first inflatable component 4 and a second inflatable component 5, wherein a first channel 11, a second channel 12 and a third channel are formed in the endotracheal cannula 1, the first channel 11, the second channel 12 and the third channel are not connected, and the third channel extends from one end to the other end of the endotracheal cannula 1; the first cuff 2 is sleeved on the periphery of the endotracheal cannula 1, the first cuff 2 is connected to the outlet of the first channel 11, and the outer diameter of the first cuff 2 is larger than the outer diameter of the endotracheal cannula 1; the second cuff 3 is sleeved on the periphery of the endotracheal cannula 1 and arranged adjacent to the first cuff 2, the second cuff 3 is connected to the outlet of the second channel 12, and the outer diameter of the second cuff 3 is larger than the outer diameter of the endotracheal cannula 1; the first inflatable component 4 is connected to the inlet of the first channel 11; the second inflatable component 5 is connected to the inlet of the second channel 12. The endotracheal intubation device provided in the embodiment of the present application is provided with two cuffs, and an inflation component is provided for each cuff to inflate the corresponding cuff through the inflation component. The inflated cuff can fix the endotracheal intubation tube 1. By inflating different cuffs, pressure fixation can be achieved at different positions of the airway, thereby avoiding long-term pressure on the local mucosa of the airway causing pressure damage to the airway instrument, reducing side effects, and providing safety for use.

[0068] In a possible embodiment, the inlet and outlet of the first channel 11 and the inlet and outlet of the second channel 12 are both located on the side wall of the endotracheal tube 1. Figure 4As shown, the outlet of the first channel 11 is closer to the internal end of the endotracheal tube 1 than the outlet of the second channel 12, and the layout position of the first cuff 2 corresponds to the outlet of the first channel 11, and the layout position of the second cuff 3 corresponds to the outlet of the second channel 12. Generally, the inlet of the first channel 11 and the inlet of the second channel 12 can be set on the same cross-section of the endotracheal tube 1, and can be arranged opposite each other. The first inflatable component 4 is sealedly connected to the inlet of the first channel 11, and the second inflatable component 5 is sealedly connected to the inlet of the second channel 12. The first inflatable component 4 and the second inflatable component 5 can both achieve inflation and deflation of the corresponding first cuff 2 and second cuff 3.

[0069] In a possible embodiment, the endotracheal intubation device further includes a bite assembly 6, which is movably sleeved on the periphery of the endotracheal tube 1 and can move between the first cuff 2 and the first inflatable assembly 4 or between the second cuff 3 and the second inflatable assembly 5.

[0070] Generally speaking, when using this application, one end of the endotracheal tube 1 needs to be inserted into the patient's airway from the oral cavity, while the other end remains outside the oral cavity. Therefore, the end of the endotracheal tube 1 inserted into the oral cavity is the internal end, and the end remaining outside the oral cavity is the external end. It can be understood that the first cuff 2 and the second cuff 3 are located near the internal end, while the entrance of the first channel 11 and the entrance of the second channel 12 are located near the external end. The bite assembly 6 can then slide between the second cuff 3 and the entrance of the first channel 11.

[0071] In one possible embodiment, the first inflation component 4 includes a first one-way valve 41, a first indicator airbag 42 and a first hose 43. The first one-way valve 41 is arranged on the first indicator airbag 42. The first indicator airbag 42 is connected to one end of the first hose 43, and the other end of the first hose 43 is connected to the inlet of the first channel 11.

[0072] Specifically, the first indicator airbag 42 is pressed to inflate the first cuff 2, thereby securing the endotracheal tube 1. An outlet can be provided on the first indicator airbag 42, and a removable cap can be provided at the outlet. When deflation is required, the first cuff 2 can be deflated by removing the cap. Alternatively, a first one-way valve 41 can be removably provided on the first indicator airbag 42. When deflation is required, the first one-way valve 41 can be removed to achieve deflation.

[0073] In one possible implementation, Figure 1-2 As shown, the first inflation component 4 includes a second one-way valve 51, a second indicator airbag 52 and a second hose 53. The second one-way valve 51 is arranged on the second indicator airbag 52. The second indicator airbag 52 is connected to one end of the second hose 53, and the other end of the second hose 53 is connected to the inlet of the second channel 12.

[0074] Specifically, the second indicator airbag 52 is pressed to inflate the second cuff 3, thereby securing the endotracheal tube 1. An air outlet can be provided on each of the second indicator airbags 52, and a removable cap can be provided at the outlet. When deflation is required, the second cuff 3 can be deflated by removing the cap. Alternatively, a second one-way valve 51 can be removably provided on the second indicator airbag 52. When deflation is required, the second one-way valve 51 can be removed to deflate the second cuff 3.

[0075] In one possible implementation, Figure 3 As shown, the bite assembly 6 includes a mouthpiece 61, a side edge 62, and a fixing belt 63. The mouthpiece 61 is an elliptical columnar structure, and a plug hole is provided in the middle of the columnar structure, and the tracheal tube 1 is inserted into the plug hole; the side edge 62 is formed by extending from one end of the mouthpiece 61 away from the first cuff 2 or the second cuff 3 to the surrounding areas, and two connecting holes 621 are provided at both ends of the side edge 62; the two ends of the fixing belt 63 are respectively fixed at the two connecting holes 621.

[0076] In a possible embodiment, the fixing belt 63 is made of elastic material. Therefore, the elastic fixing belt 63 can be put on the patient's head to achieve the fixation of the device on the patient's face.

[0077] In a possible embodiment, the mouthpiece 61 is made of silicone material to improve the comfort of using the device and avoid damage to the patient's oral cavity.

[0078] Specifically, by sleeve-mounting the mouthpiece 61 on the endotracheal tube 1 , the mouthpiece 61 can be used to open and fix the patient's oral cavity, making it easier to insert the endotracheal tube 1 into the oral cavity, while preventing the patient from biting the endotracheal tube 1 .

[0079] By forming connection holes 621 on the side edge 62 and fixing the two ends of the fixing belt 63 to the two connection holes 621 respectively, the fixing belt 63 is put on the patient's head to fix the mouthpiece 61 to the patient's face.

[0080] In a possible embodiment, the bite assembly 6 includes a locking member 64 , which is fixedly disposed on a side of the side edge 62 away from the mouthpiece 61 . The locking member 64 forms a clamping area for clamping the endotracheal tube 1 .

[0081] Furthermore, the side edge 62 extends in a direction away from the mouthpiece 61 to form a circle of flange 5, and a first threaded hole and a second threaded hole are provided on the flange 5. The locking member 64 includes a first screw 641 and a second screw 642. The first screw 641 is threadedly connected to the flange 5 through the first threaded hole, and the first screw 641 passes through one end of the first threaded hole to fix a first curved block 643; the second screw 642 is threadedly connected to the flange 5 through the second threaded hole, and the second screw 642 passes through one end of the second threaded hole to fix a second curved block 644; wherein, the first threaded hole and the second threaded hole are symmetrically distributed on both sides of the socket, and a clamping area is formed between the first curved block 643 and the second curved block 644.

[0082] Specifically, by providing a locking member 64 and relatively tightening the two screws, the endotracheal tube 1 is clamped in the clamping area between the two curved blocks, thereby achieving position limitation of the mouthpiece 61 relative to the endotracheal tube 1.

[0083] Among them, the first curved block 643 and the first screw 641 are rotationally connected and do not undergo lateral displacement, and the second curved block 644 and the second screw 642 are rotationally connected and do not undergo lateral displacement, so that when clamping the endotracheal tube 1, after the inner curved surface of the first curved block 643 contacts the endotracheal tube 1, the first screw 641 continues to rotate, and the first curved block 643 does not rotate until the endotracheal tube 1 is clamped between the two curved blocks by rotating the first screw 641 and the second screw 642.

[0084] It should be noted that the endotracheal intubation device provided in this application is a disposable item.

[0085] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology, and are not used to limit the conditions for implementation of the present invention.
