Description

Technical Field

[0001] The present invention relates to the technical field of visual intubation, and in particular to a short visual intubation tool for difficult airway treatment. Background Art

[0002] In the clinical medical field, airway management is a core operational link in scenarios such as anesthesia, emergency first aid, and intensive care. The effective treatment of difficult airways is directly related to the patient's life safety and diagnosis and treatment prognosis. According to clinical statistics, the incidence of difficult airways in the general population is approximately 1%-3%, and in special populations (such as those with obesity, maxillofacial deformities, limited neck movement, and scar contracture after burns), the incidence can be as high as over 10%. When faced with difficult airways, if an effective artificial airway cannot be established quickly and accurately, it is very easy to cause serious complications such as acute hypoxia, carbon dioxide retention, cardiac arrest, and even death of the patient. Most existing visual intubation tools are not optimized for "shortness". In emergency first aid scenarios or when the patient's body position is restricted, tools that are too long are not only inconvenient to operate, but may also increase the risk of airway injury. At the same time, when the patient has a lot of airway secretions, bleeding, or airway stenosis, the lens is easily contaminated, resulting in blurred vision and affecting intubation efficiency. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a solution to the problem that most existing visual intubation tools are not "short"; another purpose of the present invention is to provide a solution to the problem that the lens of existing visual intubation tools is easily contaminated when the patient has a lot of airway secretions, bleeding or airway stenosis.

[0004] Technical solution: A short visual intubation tool for difficult airway management, comprising a fixed circular plate, a connecting column fixedly connected to the lower surface of the fixed circular plate, and an arc-shaped inserting plate integrally formed at the bottom end of the connecting column; A rotating member is provided on the upper surface of the fixed circular plate, a connecting block is rotatably connected to the inner side of the rotating member, and a display screen is fixedly connected to the upper surface of the connecting block; A groove is provided at the rear end of the arc-shaped plug plate, a mounting groove is provided inside the groove, and a pinhole camera is embedded in the inner side wall of the mounting groove.

[0005] Furthermore, a circular cavity 1 is integrally formed inside the connecting column, a circular cavity 2 is integrally formed inside the arc-shaped insert plate, the rear end of the circular cavity 2 is connected to the interior of the groove, an L-shaped conduit is fixedly connected to the interior of the circular cavity 1, the front end of the L-shaped conduit extends to the front of the fixed circular plate, and the interior of the L-shaped conduit is connected to the interior of the circular cavity 2.

[0006] Furthermore, a fixing groove is provided inside the groove and in front of the mounting groove, a control box is fixedly connected inside the fixing groove, a piston plate 1 is slidably connected inside the control box, a connecting rod is fixedly connected to the left end of the piston plate 1, the left end of the connecting rod extends to the outside of the control box and is fixedly connected to a push plate, a movable plate is provided inside the mounting groove and on the left side of the pinhole camera, a sponge sheet is provided on the lower surface of the movable plate, and a support plate is fixedly connected to the opposite sides of the movable plate and the push plate.

[0007] Furthermore, a pressing cavity is integrally formed inside the connecting column and above the circular cavity one, and an air hole is provided inside the pressing cavity and the interior of the control box. The interior of the pressing cavity is slidably connected to a piston plate two, and two pressing rods are fixedly connected to the upper surface of the piston plate two. The top ends of the two pressing rods extend to the top of the fixed circular plate and are fixedly connected to a pressing plate.

[0008] Furthermore, a plurality of return springs are fixedly connected to the lower surface of the piston plate 2 and the inner upper surface of the pressing chamber.

[0009] Furthermore, a sealing block is provided on the outer side of the L-shaped conduit.

[0010] Furthermore, a guide groove is provided on the inner front surface of the installation groove, a sliding block is slidably connected to the inside of the guide groove, and a rear end of the sliding block is fixedly connected to the front surface of the support plate.

[0011] Beneficial Effects: The short curved insert plate of the present invention can be easily inserted into airways with narrow oral space or restricted patient position, without significantly adjusting the patient's head posture. This not only reduces the risk of airway tissue compression and injury, but also improves operational convenience in space-constrained scenarios such as emergency first aid and transport. At the same time, the short structure is combined with the display screen adjusted by the rotating part, allowing medical staff to observe airway images through the display screen without having to lean over excessively, further optimizing the operating experience. The present invention forms a dedicated tracheal tube guide channel by interconnecting the first and second circular cavities and the L-shaped catheter. During intubation, the tracheal tube can enter the second circular cavity along the L-shaped catheter and then be accurately inserted into the trachea through the channel at the groove. This guide path conforms to the anatomical direction of the airway and can effectively avoid the risk of the catheter deviating from its direction and being mistakenly inserted into the esophagus due to the lack of guidance in traditional intubation, thereby significantly reducing the difficulty of operation and making the intubation process more stable and safer. When the pinhole camera lens is blocked by stains, medical staff only need to press the pressing plate to squeeze the air through the second piston plate and push the first piston plate to move, thereby driving the support plate and the moving plate to move synchronously, so that the sponge sheet fits the lens surface to complete the wiping and cleaning. After cleaning, the reset spring can automatically drive the various components to reset, avoiding the sponge sheet from blocking the lens, so there is no need to interrupt the intubation operation or remove parts. The lens clarity can be quickly restored within a few seconds, effectively avoiding the problem of blurred vision and reduced intubation efficiency caused by lens contamination, ensuring that in complex and difficult airway scenarios, medical staff can always accurately judge the intubation position through clear images, thereby improving the success rate of intubation.

[0014] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Example like Figures 1-6As shown, a short visual intubation tool for difficult airway treatment is provided, comprising a fixed circular plate 1, a connecting column 2 being fixedly connected to the lower surface of the fixed circular plate 1, and an arc-shaped inserting plate 3 being integrally formed at the bottom end of the connecting column 2; a rotating member 4 is provided on the upper surface of the fixed circular plate 1, a connecting block 5 being rotatably connected to the inner side of the rotating member 4, and a display screen 6 being fixedly connected to the upper surface of the connecting block 5; a groove 7 is provided at the rear end of the arc-shaped inserting plate 3, a mounting groove 8 is provided inside the groove 7, and a pinhole camera 9 is embedded in the inner side wall of the mounting groove 8; When performing a difficult airway intubation operation, the medical staff first holds the fixed circular plate 1 and slowly inserts the arc-shaped plug plate 3 at the bottom end of the connecting column 2 into the patient's mouth. Because the overall device adopts a short design, the length of the arc-shaped plug plate 3 is adapted to the narrow oral space and restricted body position. During the insertion process, the tongue root or throat tissue will not be overly compressed, and there is no need to significantly adjust the patient's head posture, which effectively reduces the risk of airway damage and aspiration. After the arc-shaped plug plate 3 is inserted into the appropriate position, its front end can fit the direction of the airway. At this time, the pinhole camera 9 embedded in the mounting groove 8 is started, and the image of the anatomical structures such as the glottis and epiglottis in the airway is captured in real time through the field of view channel at the groove 7, and the signal is transmitted to the display screen 6. The medical staff Personnel can adjust the angle of the display screen 6 driven by the connecting block 5 through the rotating part 4 to clearly observe the image and assist in judging the intubation position. After confirming the position, the tracheal tube can be accurately inserted into the trachea with the guidance of the curved insert plate 3. During the process, the short curved insert plate 3 and the connecting column 2 have a compact structure and high flexibility during operation. Especially in scenarios with limited space such as emergency scenes and during transportation, medical staff can quickly complete the intubation operation and reduce the patient's hypoxia time. At the same time, the short design avoids the problems of difficult insertion of traditional long tools and inconvenient field of view adjustment, thereby improving the success rate of intubation and operational safety. In addition, the short structure of the curved insert plate 3 can reduce friction on the oral mucosa and reduce the probability of complications.

[0016] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, a circular cavity 10 is integrally formed inside the connecting column 2, and a circular cavity 2 11 is integrally formed inside the arc-shaped insert plate 3. The rear end of the circular cavity 2 11 is connected to the interior of the groove 7. An L-shaped conduit 12 is fixedly connected to the interior of the circular cavity 10. The front end of the L-shaped conduit 12 extends to the front of the fixed circular plate 1, and the interior of the L-shaped conduit 12 is connected to the interior of the circular cavity 2 11. After the curved insert plate 3 is inserted into the patient's mouth and the airway position is confirmed by the pinhole camera 9, the medical staff can align the front end of the endotracheal tube with the L-shaped tube 12 and extend it to the port in front of the fixed circular plate 1, and push the endotracheal tube along the internal channel of the L-shaped tube 12. The endotracheal tube enters the circular cavity 11 through the L-shaped tube 12, and then continues to advance along the channel connected to the groove 7 at the rear end of the circular cavity 11. Because the circular cavity 11 and the curved insert plate 3 are integrally formed and fit the direction of the airway, a stable guiding path can be provided for the endotracheal tube to prevent the tube from deviating from the direction during advancement. At the same time, the bending structure of the L-shaped tube 12 adapts to the angle between the oral cavity and the airway, reducing the friction between the endotracheal tube and the oral mucosa and throat tissue, reducing the risk of injury, and there is no need to repeatedly adjust the tube position during the guidance process. With the real-time field of view of the pinhole camera 9, the intubation accuracy and efficiency are greatly improved. In addition, the built-in guiding channel design makes the device structure more compact, which conforms to the advantages of a short tool and can still be operated smoothly in scenarios where the oral space is narrow or the body position is restricted.

[0017] like Figure 1 、 Figure 3 and Figure 4 As shown, a sealing block 27 is provided on the outside of the L-shaped conduit 12; When the device is not in use, the sealing block 27 can form a sealed cover for the insertion end port of the L-shaped catheter 12 to prevent external dust and impurities from entering the interior of the catheter and causing pollution, while preventing the insertion end of the catheter from being damaged or deformed due to collision and friction, thereby ensuring the patency and integrity of the internal channel of the catheter. When it is necessary to guide the endotracheal tube through the L-shaped catheter 12, medical staff can first remove the sealing block 27. At this time, the insertion end port of the L-shaped catheter 12 is completely exposed, which facilitates the precise insertion of the endotracheal tube. The detachable design of the sealing block 27 is easy to operate and will not affect the efficiency of the intubation process.

[0018] like Figures 1-6 As shown, a fixing groove 13 is provided inside the groove 7 and in front of the mounting groove 8. A control box 14 is fixedly connected to the inside of the fixing groove 13. A piston plate 15 is slidably connected to the inside of the control box 14. The left end of the piston plate 15 is fixedly connected to a connecting rod 16. The left end of the connecting rod 16 extends to the outside of the control box 14 and is fixedly connected to a push plate 17. A movable plate 18 is provided inside the mounting groove 8 and on the left side of the pinhole camera 9. A sponge sheet 19 is provided on the lower surface of the movable plate 18. A support plate 20 is fixedly connected to the opposite sides of the movable plate 18 and the push plate 17. A pressing chamber 21 is integrally formed inside the connecting column 2 and above the circular chamber 10. An air hole 22 is provided inside the pressing chamber 21 and inside the control box 14. A piston plate 23 is slidably connected to the inside of the pressing chamber 21. Two pressing rods 24 are fixedly connected to the upper surface of the piston plate 23. The top ends of the two pressing rods 24 extend above the fixed circular plate 1 and are fixedly connected to a pressing plate 25. When the arc-shaped plug plate 3 is inserted into the patient's mouth, if the pinhole camera 9 lens is contaminated due to excessive airway secretions, bleeding or airway stenosis, the medical staff can press the set pressing plate 25 to drive the two pressing rods 24 to push the piston plate 23 in the pressing chamber 21 to slide downward. The piston plate 23 squeezes the air in the pressing chamber 21, so that the air enters the control box 14 through the air hole 22, pushing the piston plate 15 in the control box 14 to move. The piston plate 15 drives the push plate 17 to move through the connecting rod 16, and the push plate 17 is opened again. The support plate 20 drives the movable plate 18 in the installation slot 8 to move, so that the sponge sheet 19 on the lower surface of the movable plate 18 fits against the lens surface of the pinhole camera 9 and wipes it, absorbing the stains on the lens. The intubation operation does not need to be interrupted during the process, and there is no need to disassemble or replace parts. The lens clarity can be quickly restored to avoid prolonging the intubation time or causing intubation errors due to blurred vision. It is suitable for complex and difficult airway scenes such as heavy secretions and bleeding, ensuring that the intubation operation is carried out continuously and accurately. At the same time, no additional cleaning tools are required, which is in line with the compact and convenient short design advantage of the device.

[0019] like Figure 3 and Figure 4 As shown, the lower surface of the piston plate 23 and the inner upper surface of the pressing chamber 21 are fixedly connected with a plurality of return springs 26; When the lens is cleaned, the pressing plate 25 is released, and the compressed multiple reset springs 26 release elastic potential energy, pushing the piston plate 2 23 to reset upward, and then the air pressure drives the piston plate 1 15, connecting rod 16, push plate 17, support plate 20 and movable plate 18 to reset synchronously, so that the sponge sheet 19 can quickly leave the lens area of ​​the pinhole camera 9, avoiding the sponge sheet 19 staying for a long time to block the lens line of sight, ensuring that the lens can continue to clearly capture the airway image during the subsequent intubation process, and further ensuring the continuity and accuracy of the intubation operation.

[0020] like Figure 5 and Figure 6 As shown, a guide groove 28 is provided on the inner front surface of the mounting groove 8, a sliding block 29 is slidably connected to the inner portion of the guide groove 28, and the rear end of the sliding block 29 is fixedly connected to the front surface of the support plate 20; When cleaning the lens surface, the support plate 20 drives the sliding block 29 to slide synchronously along the guide groove 28 during its movement. The guide groove 28 forms a limiting guide for the sliding block 29 to prevent the support plate 20 from deviating or shaking during the movement, ensuring that the support plate 20 drives the moving plate 18 and the sponge sheet 19 on the lower surface to always stably adhere to the lens surface of the pinhole camera 9 to perform a straight line wiping motion, preventing the sponge sheet 19 from wiping out of place or missing stains due to the deviation of the support plate 20, thereby improving the cleaning effect and lens protection.

[0021] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
