[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 2 - Figure 4 An embodiment of the present invention is as follows: an oropharyngeal airway in which a gastroscope can be placed, comprising a bite tube 1, a sliding block 8 is slidably connected inside the bite tube 1, a pharyngeal tube 3 is fixedly connected to one side of the outer wall of the sliding block 8, a card slot 10 is provided on one side of the inner side of the sliding block 8, a driving ring 4 is slidably connected inside the bite tube 1, a spring 13 is arranged inside the bite tube 1, one end of the spring 13 is fixedly connected to the outer wall of the driving ring 4, and the other end of the spring 13 is fixedly connected to the bite tube 1, both sides of the bite tube 1 are slidably connected with an insert block 16, the outer wall of the insert block 16 is slidably connected to the inside of the driving ring 4, a spring 2 15 is sleeved on one side of the outer wall of the insert block 16, and the spring 2 1 One end of the spring 15 is fixedly connected to one side of the outer wall of the plug block 16, and the other end of the spring 15 is fixedly connected to the inner wall of the bite tube 1. One side of the outer wall of the plug block 16 is fixedly connected to the push block 14. A plurality of air guide grooves 17 are provided inside the bite tube 1. A plurality of air bags 12 are fixedly connected to the inner wall of the bite tube 1. The inside of the air guide grooves 17 is connected to the inside of the air bags 12. A blocking component is provided on the outer wall of the bite tube 1. The blocking component is used to prevent the bite tube 1 or the throat tube 3 from going too deep. The blocking component includes a blocking ring 9 and a baffle 2. The inner wall of the baffle 2 is fixedly connected to one side of the outer wall of the bite tube 1. The inside of the blocking ring 9 is fixedly connected to one side of the outer wall of the sliding block 8. The outer wall of the blocking ring 9 is slidably connected to the bite tube 1.

[0034] Specifically, when the device is worn, the patient is first asked to gently hold the bite tube 1 in his mouth. When the patient falls asleep or is in an anesthetized state, the sliding block 8 can be carefully and smoothly pushed to slide inside the bite tube 1. During this process, the pharyngeal tube 3 can be inserted into the patient's throat to prepare for subsequent examinations or treatments. The bite tube 1 and the pharyngeal tube 3 are made of soft medical silicone with good biocompatibility, which is convenient for ensuring the comfort of the patient. At the same time, the elastic force generated by the spring 13 can be overcome by pressing the drive ring 4. When the drive ring 4 is pressed, it can effectively and quickly inject the air stored in the air guide groove 17 into the airbag 12. As the air is continuously injected, the airbag 12 will gradually expand and... By inserting the sliding block 8 into the specially designed card slot 10 on the outer wall of the sliding block 8, the stable state of the sliding block 8 can be effectively maintained in this way to ensure that it will not slide or shift accidentally during use, and the drive ring 4 will be accurately inserted into the corresponding position by the insert block 16, so that the drive ring 4 can be kept fixed, further enhancing the stability and reliability of the entire structure. The instrument can then smoothly extend the gastroscope through the spacious space reserved inside the bite tube 1 and the pharyngeal tube 3. This design not only provides sufficient space for the operation of the gastroscope, but also effectively ensures the safety of the gastroscope during the entry and exit process, thereby playing an important auxiliary role when the gastroscope is used, and providing strong support for medical operations.

[0035] Reference Figure 1 , Figure 2 and Figure 6 , both sides of the baffle 2 are fixedly connected with fixing belts 5, one side of the fixing belt 5 is fixedly connected with a fixing block 7, and the other side of the fixing belt 5 is fixedly connected with a fixing block 6, a slot 19 is provided inside the fixing block 7, one side of the outer wall of the fixing block 6 is fixedly connected with an insert block 20, and the outer wall of the insert block 20 is slidably connected inside the slot 19, and both sides of the fixing block 7 are provided with a slot 18, and the slot 18 is provided on the inner wall of the slot 19, and both sides of the insert block 20 are fixedly connected with spring pieces 21, and one side of the outer wall of the spring piece 21 is fixedly connected with a wedge-shaped card block 11, and the outer wall of the wedge-shaped card block 11 is slidably connected inside the slot 18;

[0036] Specifically, when the device is used, the bite tube 1 can be placed in the patient's mouth, and then the fixing belt 5 can be wrapped around the patient's head. At this time, the fixing block 1 6 on one side of the fixing belt 5 is connected and fixed with the fixing block 2 7 on the other side of the fixing belt 5, and the insert block 20 on the fixing block 1 6 will be inserted into the slot 19 opened inside the fixing block 2 7. During the process of inserting the insert block 20 into the slot 19, the spring piece 21 of the fixed wedge-shaped block 11 will be deformed due to the inner wall pressure of the slot 19, so that the wedge-shaped block 11 will retract into the insert block 20. After the insert block 20 is fully inserted into the slot 19, the wedge-shaped block 11 will be reset under the action of the rebound force of the spring piece 21, thereby being stuck into the card holes on both sides of the slot 19. The second slot 18 is inserted into the second slot 18, so that the second plug-in block 20 is firmly fixed in the slot 19. When it needs to be removed, the wedge-shaped card block 11 with a smooth surface can be pressed to make the wedge-shaped card block 11 overcome the elastic force of the spring sheet 21 and retract into the second plug-in block 20, so that the second plug-in block 20 can be pulled out from the slot 19. In this device, the nylon material of the fixing belt 5 has good elasticity and flexibility, which can not only ensure a stable fixing effect, but also adapt to the size and shape of different patients' heads, improve the wearing comfort and fit. In addition, the fixing and disassembly operations of the device are simple and quick, which improves the work efficiency of medical staff, reduces the operation time, and provides patients with more timely and efficient medical services.

[0037] Working principle: when the device is used, the bite tube 1 can be placed in the patient's mouth, and then the fixing belt 5 is wrapped around the patient's head, then the fixing block 1 6 on one side of the fixing belt 5 is connected and fixed with the fixing block 2 7 on the other side of the fixing belt 5, and the insert block 2 20 on the fixing block 1 6 will be inserted into the slot 19 opened inside the fixing block 2 7. During the process of inserting the insert block 20 into the slot 19, the inner wall pressure of the slot 19 will cause the spring piece 21 of the fixed wedge-shaped card block 11 to deform, so that the wedge-shaped card block 11 is retracted into the inside of the insert block 20. After the insert block 20 is completely inserted into the slot 19, the wedge-shaped card block 11 will be reset under the action of the spring piece 21, and then be stuck into the card grooves 2 18 on both sides of the slot 19, so that the insert block 20 is fixed inside the slot 19. When it is removed, the wedge-shaped card block 11 can be pressed to make the wedge The shaped card block 11 overcomes the force of the spring piece 21 and retracts into the inside of the insert block 20, so that the insert block 20 can be pulled out from the inside of the slot 19. When the device is worn, the patient will first hold the bite tube 1 in his mouth. After the patient falls asleep or is anesthetized, the sliding block 8 can be pushed to slide inside the bite tube 1, so that the pharyngeal tube 3 is inserted into the patient's throat. At the same time, the force of the spring 13 can be overcome to press the drive ring 4, and the drive ring 4 can inject the air inside the air guide groove 17 into the air bag 12 to inflate the air bag 12, and the air bag 12 will be stuck in the card groove 10 on the outer wall of the sliding block 8, so that the sliding block 8 can be kept stable. At the same time, the drive ring 4 will be inserted by the insert block 16, so that the drive ring 4 remains fixed, and the device can extend the gastroscope through the internal space of the bite tube 1 and the pharyngeal tube 3, thereby assisting the use of the gastroscope.
