[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] like Figures 1-2 As shown, an endotracheal tube for laryngeal surgery includes an airway 1; the airway 1 has an inner sac channel 2, an outer sac channel 3, and a main tracheal lumen 4; the inner sac channel 2, the outer sac channel 3, and the main tracheal lumen 4 are respectively provided with an inner sac inflation tube 5, an outer sac inflation tube 6, and an endotracheal connector 7 at their rear ends; an inner sac inflation device 10 is connected to the inner sac inflation tube 5, and an outer sac inflation device 20 is connected to the outer sac inflation tube 6; the airway 1 has an inner sac 8 and an outer sac 9; the inner sac 8 and the outer sac 9 cover the airway 1, with the inner sac 8 placed inside the outer sac 9, the inner sac inflation tube 5 communicating with the inner sac 8, and the outer sac inflation tube 6 communicating with the outer sac 9; a mouthpiece cannula 30 is fitted onto the airway 1.

[0025] In this embodiment, the inner bladder 8 and the outer bladder 9 work together to make the use of endotracheal intubation safer. Compared with the traditional single-bladder device, it avoids the pain of re-intubation for the patient after the single bladder leaks. At the same time, the inner bladder 8 and the outer bladder 9 cover the ventilation tube 1, which is a more ingenious design.

[0026] In this embodiment, the inner capsule 8 is made of TPU material. After the outer capsule 9 is damaged, the inner capsule 8 can also play the same role, preventing the patient from suffering from the pain caused by the second intubation, and reducing the risk of the second intubation surgery.

[0027] The tail end of the inner capsule 8 is flush with the tail end of the outer capsule 9, which can assist in the positioning of the airway 1 during use.

[0028] The inner capsule 8, outer capsule 9, and airway 1 are all made of transparent material; the positional changes of the inner capsule 8, outer capsule 9, and airway 1 can be directly observed, enabling precise positioning of the inner capsule 8 and outer capsule 9. This avoids the positional deviations caused by touch positioning or finger pressure touch positioning in existing technologies, thereby improving positioning accuracy and ensuring surgical results.

[0029] like Figure 3 As shown, the bite cannula 30 includes a cannula body 31, and a guide hole 32 is formed along the length direction of the cannula body 31. The ventilation tube 1 passes through the guide hole 32 to assemble the bite cannula 30 onto the ventilation tube 1. In this embodiment, the bite cannula 30 is provided and assembled onto the ventilation tube 1 to facilitate the patient to bite the bite cannula during use, thereby ensuring the safety of the ventilation tube 1.

[0030] The cannula body 31 has guide portions 33 symmetrically formed at both ends, and the outer diameter of the guide portions 33 gradually decreases from the middle to both sides. By adopting the above scheme, the guide portions 33 are delayed inward during the insertion of the bite cannula 30, which allows the patient to bite the cannula body 31, ensuring the convenience of inserting the ventilation tube 1 and reducing tissue damage and discomfort to the patient.

[0031] The two sides of the cannula body 31 are provided with guide surfaces 34, which extend to the guide portion 33. The guide surfaces 34 facilitate the patient's gripping by hand, increase the contact area between the cannula body and the patient's hand, and facilitate operation.

[0032] The ventilation tube 1 has an arc-shaped front end; the arc-shaped front end facilitates tube placement, reduces collateral damage during insertion, prevents damage to the patient's organs and tissues during tube insertion, and avoids pain caused by tissue abrasion.

[0033] A hydrophilic lubricating coating is cured on the outer surface of the ventilation tube 1 and the outer capsule 9. The hydrophilic lubricating coating is cured on the outer surface of the ventilation tube 1 and the outer capsule 9. It can produce a lubricating effect after being immersed in water for a few seconds, which greatly reduces the friction between the catheter and the human body, enhances the pushability of the product during use, and reduces tissue damage and discomfort to patients.

[0034] A first spring 50 is provided inside the main tracheal lumen 4. The first spring 50 has a spiral structure and is arranged along the length of the main tracheal lumen 4. The first spring 50 is located inside the side wall of the main tracheal lumen 4. The first spring 50 ensures the flexibility of the airway 1 while ensuring the strength of the airway 1.

[0035] like Figure 4 As shown, the inner balloon inflation device 10 includes an inner balloon one-way valve 11 and an inner cannula indicator balloon 12 that are adapted to each other; the outer balloon inflation device 20 includes an outer balloon one-way valve 21 and an outer cannula indicator balloon 22 that are adapted to each other; wherein, the inner balloon one-way valve 11 and the outer balloon one-way valve 21 have the same structure.

[0036] The inner balloon one-way valve 11 works in conjunction with the inner balloon indicator balloon 12, and the outer balloon one-way valve 21 works in conjunction with the outer balloon indicator balloon 22. The inner balloon indicator balloon 12 can monitor the pressure value of the inner balloon 8, and the outer balloon indicator balloon 22 can monitor the pressure value of the outer balloon 9. Not only can it effectively maintain a constant pressure in the inner balloon indicator balloon 12 and the outer balloon indicator balloon 22 during each use, but after monitoring the pressure, the inner balloon one-way valve 11 and the outer balloon one-way valve 21 can be operated to keep the pressure of the inner balloon indicator balloon 12 and the outer balloon indicator balloon 22 stable, thereby effectively preventing gas leakage and ensuring the airway seal, reducing the patient's pain.

[0037] Specifically, the inner bladder one-way valve 12 includes an outer tube 40 and an inner tube 41; a connecting plate 42 is fixed at the connection between the outer tube 40 and the inner tube 41, and a through hole 43 is formed on the connecting plate 42. A sliding rod 44 is slidably connected in the through hole 43. A core plug 49 is fixed at one end of the sliding rod 44, and a sealing ring 45, a limiting ring 46, and a second spring 47 are sequentially sleeved on the other end of the sliding rod 44; wherein, the core plug 49 is located in the cavity of the outer tube 40, and the sealing ring 45, the limiting ring 46, and the second spring 47 are located in the cavity of the inner tube 41.

[0038] A protrusion 48 is fixedly provided on the outer circumferential side between the outer tube 40 and the inner tube 41; the protrusion 48 corresponds to the position of the connecting plate 42 and is attached to the inner tube indicating balloon 12; at the same time, the inner tube 41 is connected to the connector 13 on the inner tube indicating balloon 12; the second spring 47 located in the inner tube 41 extends into the connector 13; the contact area between the protrusion 48 and the inner tube indicating balloon 12 is increased, the sealing performance between the inner balloon one-way valve 12 and the inner balloon one-way valve 11 is further improved, and the safety of use is further guaranteed.
