Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endotracheal intubation device and its method of use. Background Technology

[0002] Airway management is a critical procedure in anesthesia, emergency medicine, and intensive care, with its core objective being to establish ventilation or intubation access quickly and effectively while ensuring patient safety. Currently, various types of devices are commonly used for airway management in clinical practice, including but not limited to laryngeal mask airways, oral intubation devices, and other intubation aids.

[0003] First, a classic laryngeal mask airway (LMA) typically consists of a main body and an inflatable cuff. After insertion, the cuff rests around the laryngeal inlet to create an airway above the glottis. This type of LMA offers advantages such as easy insertion and minimal irritation, primarily used for maintaining ventilation. However, while the classic LMA prioritizes ventilation, and although successful intubation can be achieved in some cases with the operator's experience, the lack of a stable, dedicated intubation channel structure limits the success rate and repeatability of intubation, making it difficult to reliably and stably support endotracheal intubation via the LMA.

[0004] Secondly, the intubation-type laryngeal mask airway (LMA) is an improvement on the classic LMA structure. It features an internal intubation channel, allowing the operator to insert the endotracheal tube after the LMA is in place, thus achieving endotracheal intubation. Specifically, the intubation-type LMA primarily uses two methods for intubation: blind intubation, where the operator pushes the endotracheal tube based on experience and anatomical structure; and fiberoptic bronchoscopy-assisted intubation, using additional equipment for guidance. Therefore, although the intubation-type LMA expands the application scenarios of the LMA to some extent, its intubation channel direction is usually fixed. In actual operation, it lacks the ability to finely adjust the direction during intubation. When the distal end of the intubation channel is not properly aligned with the glottic axis, the operator often has to repeatedly adjust the position of the entire LMA or attempt intubation multiple times to complete the operation, increasing the difficulty and potential risks.

[0005] Finally, visual airway devices, such as video laryngoscopes, primarily expose the glottis region through imaging to assist operators in determining the timing of intubation, thereby improving the problem of insufficient glottis exposure under traditional blind intubation conditions. However, the structural function of these visual airway devices focuses on the visualization of the glottis and does not itself form an auxiliary intubation channel for the endotracheal tube to pass through or be restricted. During intubation, the endotracheal tube usually needs to be advanced independently outside the device, and the intubation direction mainly depends on the operator's hand operation experience and the adjustment of the overall posture of the device. In other words, although visual airway devices improve the visibility of the glottis to a certain extent, their role is mainly limited to providing visual information about the glottis region. They are unable to provide structural constraints on the insertion path of the endotracheal tube during intubation, nor can they achieve the effect of direct or active adjustment of the intubation channel direction.

[0006] Therefore, existing technologies generally have shortcomings, namely, there is no overall technical solution that can comprehensively utilize visual information during intubation and actively, precisely and controllably adjust the intubation channel to achieve effective guidance of the endotracheal tube insertion path.

[0007] Further analysis from the perspective of the technical implementation mechanism reveals that the reason why existing airway management devices are unable to achieve precise control of the intubation channel direction during intubation is mainly due to the following limitations at the technical mechanism level: 1. The insertion channel direction of existing intubation devices is usually a fixed structure, making it difficult to make fine adjustments to the insertion channel during the intubation process; 2. When the intubation channel is not properly aligned with the glottic axis, it is often necessary to adjust it by moving the entire instrument or repeatedly trying to insert the tube. The operation is relatively crude, which increases the complexity of the operation and potential risks. 3. Although some existing technologies have introduced visualization methods, there is no direct correlation mechanism between the visualized information and the intubation action, and the glottal image is difficult to effectively convert into the basis for adjusting the intubation direction; 4. In special circumstances such as obesity, limited neck mobility, or anatomical deformities, the above problems become more prominent, further increasing the intubation failure rate and the risk of complications.

[0008] Therefore, how to overcome the limitations of the above-mentioned fine control, achieve effective adjustment of the intubation channel, and rationally guide the endotracheal tube to perform intubation for different patients with different laryngeal conditions is a problem that needs to be solved by people in this field. Summary of the Invention

[0009] The purpose of this invention is to provide an endotracheal intubation device and its method of use, so as to overcome the limitations of fine control in the prior art, realize the effective adjustment of the intubation channel, and rationally guide the endotracheal tube, which is suitable for intubation in different patients with different laryngeal conditions.

[0010] To achieve this objective, the present invention adopts the following technical solution: An endotracheal intubation device, comprising: The device comprises an intubation body, a guide tube, an adjustment mechanism, and a visualization component. The guide tube has two ends, a proximal end and a distal end, respectively, with the proximal end connected to the intubation body. The visualization component is mounted on the distal end and is used to acquire images of the glottic region. The guide tube has a bent section, and the adjustment mechanism is located at the end of the intubation body opposite to the guide tube and is used to adjust the bending angle of the bent section to change the bending direction of the distal end of the guide tube.

[0011] Alternatively, the guide tube is slidably connected to the insertion tube body, and the two are arranged through each other along their respective axial directions.

[0012] Optionally, the guide tube has an insertion channel in its inner lumen, through which the endotracheal tube can pass to enter the glottic region.

[0013] Alternatively, the bent section may be made of a flexible material.

[0014] Alternatively, the visualization component is provided in two sets, and the two sets of visualization components are symmetrically distributed on the end face of the distal end of the guide tube.

[0015] Optionally, the visualization component is communicatively connected to the adjustment mechanism, and the adjustment mechanism has an image acquisition module and an image analysis module. The image acquisition module can acquire monitoring images of the visualization component, and the image analysis module can analyze the relative relationship between the glottis region and the distal end to control the bending angle of the bend.

[0016] Optionally, the adjustment mechanism can be manually, semi-automatically, or fully automatically control the bending angle of the bend.

[0017] Alternatively, the end of the bent section near the proximal end can extend out of the cannula body, and the end of the bent section near the distal end is spaced apart from the distal end.

[0018] On the other hand, the method of using the endotracheal intubation device includes the following steps: S1. The intubation body and the guide tube are placed together in the patient's pharynx and positioned. S2. Use this visualization component to obtain an image of the glottic region of the patient; S3. Determine the relative relationship between the distal end of the guide tube and the glottis based on the image of the glottis region obtained by the visualization component; S4. Adjust the bending angle of the bend in the guide tube using the adjustment mechanism to adjust the orientation of the opening at the distal end; S5. Guide the endotracheal tube through the main body of the intubation tube and the guide tube in sequence and then into the glottic region.

[0019] Optionally, it also includes: S6. Based on the image of the glottis region updated in real time by the visualization component, repeat steps S3-S5 to dynamically update the orientation of the distal opening and achieve closed-loop adjustment.

[0020] The beneficial effects of this invention are: This invention addresses the problems of precise control over the intubation direction, reliance on experience, and repeated attempts inherent in existing intubation techniques. It provides a tracheal intubation device with visualization capabilities and adjustable intubation direction during intubation. Specifically, the intubation body of the device can be inserted into the patient's pharynx and provides positioning support for the endotracheal tube after positioning. Simultaneously, with the visualization component, images of the glottic region can be acquired for real-time observation. Furthermore, the bending angle of the bend in the guide tube can be adjusted by the adjustment mechanism, changing the bending direction of the distal end of the guide tube and thus guiding the tube appropriately to suit different patients' laryngeal conditions, ensuring smooth entry of the endotracheal tube into the glottis. Correspondingly, in the intubation method using the device, the relative relationship between the distal end of the guide tube and the glottis can be determined by combining the glottic region image acquired by the visualization component. The bending angle of the bend in the guide tube can then be precisely adjusted by the adjustment mechanism, effectively overcoming the limitations of precise control during intubation in existing techniques and achieving effective adjustment of the intubation direction.

[0030] Therefore, existing technologies generally have shortcomings, namely, there is no overall technical solution that can comprehensively utilize visual information during intubation and actively, precisely and controllably adjust the intubation channel to achieve effective guidance of the endotracheal tube insertion path.

[0031] Further analysis from the perspective of the technical implementation mechanism reveals that the reason why existing airway management devices are unable to achieve precise control of the intubation channel direction during intubation is mainly due to the following limitations at the technical mechanism level: 1.

[0032] Therefore, how to overcome the limitations of the above-mentioned fine control, achieve effective adjustment of the intubation channel, and rationally guide the endotracheal tube to perform intubation for different patients with different laryngeal conditions is a problem that needs to be solved by people in this field.

[0033] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 4 As shown, this embodiment provides an endotracheal intubation device, including an intubation body 10, a guide tube 20, an adjustment mechanism 30, and a visualization component 40. The two ends of the guide tube 20 are respectively set as a proximal end and a distal end, and the proximal end is connected to the intubation body 10. The visualization component 40 is installed on the distal end and is used to acquire images of the glottic region. The guide tube 20 has a bent section 21. The adjustment mechanism 30 is located at the end of the intubation body 10 away from the guide tube 20 and is used to adjust the bending angle of the bent section 21 to change the bending direction of the distal end of the guide tube 20.

[0035] The method of using an endotracheal intubation device includes the following steps: S1. The intubation body 10 and the guide tube 20 are placed together in the patient's pharynx and positioned. S2. Use visualization component 40 to acquire an image of the patient's glottic region; S3. Determine the relative relationship between the distal end of the guide tube 20 and the glottis based on the image of the glottic region obtained by the visualization component 40. S4. Adjust the bending angle of the bent section 21 of the guide tube 20 by adjusting the adjustment mechanism 30 to adjust the orientation of the opening at the far end. S5. The endotracheal tube is inserted into the glottic region after passing through the main body 10 and the guide tube 20 in sequence.

[0036] Specifically, this embodiment addresses the problems in existing technologies, such as difficulty in precisely controlling the intubation direction during intubation, reliance on experience, and the tendency to repeat attempts. It provides a tracheal intubation device with visualization capabilities and adjustable intubation direction during intubation. Specifically, in this embodiment, the intubation body 10 of the device can be inserted into the patient's pharynx and provides positioning support for the endotracheal tube after positioning. Simultaneously, in conjunction with the visualization component 40, it can acquire images of the glottic region for real-time observation. Furthermore, by adjusting the bending angle of the bend section 21 on the guide tube 20 through the adjustment mechanism 30, the bending direction of the distal end of the guide tube 20 can be changed, thereby providing reasonable guidance for the tube to suit different patients' laryngeal conditions and ensuring smooth entry of the endotracheal tube into the glottis. Accordingly, in the method of intubation using the endotracheal intubation device in this embodiment, the relative relationship between the distal end of the guide tube and the glottis can be determined by combining the image of the glottic region obtained by the visualization component 40. Then, the bending angle of the bending section 21 can be precisely adjusted by the adjustment mechanism 30, which effectively overcomes the limitation of fine control in the intubation process in the prior art and realizes the effective adjustment of the intubation direction.

[0037] The specific structure of the endotracheal intubation device in this embodiment is described below.

[0038] like Figures 1-4 As shown, in this embodiment, the endotracheal intubation device includes an intubation body 10, a guide tube 20, an adjustment mechanism 30, and a visualization component 40. The intubation body 10 and the guide tube 20 are slidably connected and extend through each other along their respective axes. This facilitates extending the overall length of the endotracheal intubation device, ensuring its insertion into the patient's glottic region and guaranteeing stable insertion of the subsequent endotracheal tube. For example, as... Figure 1 As shown, in this embodiment, the outer diameter of the guide tube 20 can be set to be larger than the outer diameter of the insertion body 10, such as... Figure 3 and Figure 4 As shown, the outer diameter of the cannula body 10 can also be set to be larger than the outer diameter of the guide tube 20, so that the guide tube 20 can be slidably placed inside the cannula body 10. The specific setting can be adjusted according to actual needs, and there is no limitation here.

[0039] Optionally, the intubation body 10 has a certain curvature, the specific curvature of which can be adjusted as needed. Further, the guide tube 20 has a proximal end and a distal end, with the proximal end connected to the intubation body 10 and the distal end used to install the visualization component 40. This allows for the acquisition of images of the glottic region through the visualization component 40, facilitating real-time monitoring by medical personnel of the position of the endotracheal intubation device in the patient's throat.

[0040] Combination Figures 2-4As shown, in this embodiment, two sets of visualization components 40 are provided, and the two sets of visualization components 40 are symmetrically distributed on the distal end face of the guide tube 20 to ensure that the visualization components 40 provide comprehensive monitoring of the patient's glottic region without blind spots. Specifically, in this embodiment, the visualization components 40 are distributed on the upper and lower sides of the distal end face of the guide tube 20 to ensure that the monitoring area can completely cover the patient's glottic region, thereby ensuring a clear and accurate monitoring image and improving the accuracy of endotracheal intubation. Exemplarily, the visualization components 40 are embedded in the outer wall of the guide tube 20 to ensure that the visualization components 40 do not affect the movement of the endotracheal tube in the lumen of the guide tube 20, while ensuring the signal transmission of the visualization components 40.

[0041] In this embodiment, both the intubation body 10 and the guide tube 20 are arranged through each other along their respective axes, and the inner cavity of the guide tube 20 is provided with an intubation channel 201. The endotracheal tube can pass through the inner cavity of the intubation body 10 and the intubation channel 201 in sequence before entering the glottic region, so as to ensure the smooth insertion of the endotracheal tube. Correspondingly, the inner diameter of the intubation channel 201 is set to correspond to the outer diameter of the endotracheal tube, so as to ensure that the endotracheal tube can move smoothly within the intubation channel 201 without obstruction, so as not to affect the subsequent operation of medical staff.

[0042] Furthermore, an adjustment mechanism 30 is provided at the end of the intubation body 10 opposite to the guide tube 20, and the guide tube 20 has a bent section 21. The adjustment mechanism 30 can change the bending angle of the bent section 21, thereby changing the bending direction of the distal end of the guide tube 20, making it fit more closely to the patient's trachea and ensuring that the endotracheal tube can be accurately inserted into the patient's glottic region. Specifically, the bent section 21 deforms under external force or driving action, causing the distal opening of the intubation channel 201 to deflect, thereby achieving fine adjustment and guidance of the orientation of the distal opening of the guide tube 20. This reduces or avoids the need to simply move the entire endotracheal intubation device or adjust its overall posture, or repeatedly attempt intubation to correct the direction.

[0043] For example, the bending segment 21 is made of a flexible material to facilitate bending adjustment. Furthermore, the bending segment 21 can be implemented in ways including but not limited to cable-driven bending, flexible material bending under force, micro-motor-driven bending, and shape memory material-driven bending.

[0044] Optionally, the visualization component 40 is communicatively connected to the adjustment mechanism 30, and the adjustment mechanism 30 has an image acquisition module and an image analysis module. The image acquisition module can acquire the monitoring image of the visualization component 40, and the image analysis module can analyze the relative relationship between the glottal region and the distal end to control the bending angle of the bending segment 21, thereby achieving automated control. However, the driving source of the adjustment mechanism 30 is not limited to the analysis of the monitoring image of the visualization component 40. Optionally, the adjustment mechanism 30 is used to drive the bending segment 21 to bend to change the opening orientation of the distal end, and adjusting the shooting direction of the visualization component 40 is not a necessary method.

[0045] Specifically, in this embodiment, the adjustment mechanism 30 of the endotracheal intubation device includes at least an image acquisition module for acquiring an image of the glottic region; an image analysis module for analyzing the relative relationship between the glottic position and the distal opening of the intubation channel; a control decision module for generating an intubation direction adjustment control command based on the analysis results; and an execution module for driving the direction adjustment mechanism to change the orientation of the distal opening of the intubation channel according to the control command. Exemplarily, this embodiment does not limit the specific image processing algorithm or control logic; the image analysis module may include an image processing unit implemented based on rules, models, or machine learning. Optionally, during intubation, the adjustment mechanism 30 may also continuously update the intubation direction to adjust the command based on changes in the relative position between the image of the glottic region and the distal opening, thereby forming a dynamic closed-loop adjustment of the intubation direction.

[0046] Specifically, the adjustment mechanism 30 can manually, semi-automatically, or fully automatically control the bending angle of the bending section 21. That is, medical staff can directly control the adjustment mechanism 30 as needed, or use it in conjunction with the visualization component 40 for semi-automatic control, or rely entirely on the monitoring images provided by the visualization component 40 for automated control. The specific control method can be selected as needed or combined with each other, and no restrictions are imposed here.

[0047] For example, in the manual control mode, the operator directly controls the bending segment 21 to bend based on the image of the glottis region acquired by the visualization component 40, thereby adjusting the orientation and change range of the distal opening of the intubation channel 201; in the semi-automatic control mode, the system analyzes the relative positional relationship between the distal opening of the intubation channel 201 and the glottis based on the acquired image of the glottis region, and generates an intubation direction adjustment suggestion, which is then confirmed by the operator and executed accordingly; in the automatic control mode, the system automatically generates an intubation direction adjustment control command based on the image of the glottis region, and controls the direction adjustment mechanism to complete the adjustment of the orientation of the distal opening of the intubation channel. Specifically, this embodiment does not limit the specific implementation of the image processing method, control logic, or algorithm, and the above control methods can be used individually or in combination according to actual application requirements.

[0048] Specifically, in this embodiment, the end of the bent section 21 near the proximal end can extend out of the intubation body 10, and the end of the bent section 21 near the distal end is spaced apart from the distal end. Thus, when the adjusting mechanism 30 controls the bent section 21 to bend, there will be no movement interference between the bent section and the intubation body 10. Furthermore, due to the spaced arrangement between the bent section 21 and the distal end, the insertion direction of the subsequent endotracheal tube can be further guided, avoiding the endotracheal tube from being directly extended after the bent section 21 extends out and the bending angle of the bent section 21 changes, so that the change of the endotracheal tube is not significant and does not affect the intubation effect.

[0049] For example, in some embodiments, the endotracheal intubation device may be made with reference to a laryngeal mask airway structure, or with reference to a guide structure for oral intubation or other structures suitable for insertion into the pharynx and for positioning the intubation channel, so as to improve the success rate of endotracheal intubation, reduce the difficulty of intubation, reduce reliance on the operator's experience, reduce tissue damage to the patient caused by repeated intubation attempts, and improve the safety of the operation.

[0050] The following is a detailed description of how to use the endotracheal intubation device in this embodiment.

[0051] Combination Figures 1-4 The method of using the endotracheal intubation device, as shown, includes the following steps: S1. The intubation body 10 and the guide tube 20 are placed together in the patient's pharynx and positioned. S2. Use visualization component 40 to acquire an image of the patient's glottic region; S3. Determine the relative relationship between the distal end of the guide tube 20 and the glottis based on the image of the glottic region obtained by the visualization component 40. S4. Adjust the bending angle of the bent section 21 of the guide tube 20 by adjusting the adjustment mechanism 30 to adjust the orientation of the opening at the far end. S5. The endotracheal tube is inserted into the glottic region after passing through the main body 10 and the guide tube 20 in sequence.

[0052] S6. Based on the image of the glottis region updated in real time by the visualization component 40, repeat steps S3-S5 to dynamically update the orientation of the distal opening and achieve closed-loop adjustment.

[0053] In summary, this embodiment not only introduces an adjustable intubation direction structure through the endotracheal intubation device, allowing the intubation channel 201 to change direction during intubation even after the device is in place, without being restricted by a fixed structure; it also enables controllable adjustment of the distal opening direction during intubation, avoiding the need to correct the direction solely by moving the entire endotracheal intubation device or repeatedly attempting intubation; simultaneously, it establishes a direct correlation mechanism between visual information and the direction adjustment of the intubation channel 201, enabling the glottic region image to serve as a basis for intubation direction adjustment during the intubation process; finally, at the structural and system level, it provides a universal foundation for various control methods, thereby supporting the implementation of manual control, semi-automatic control, and automatic or intelligent control methods.

[0054] Compared with the prior art, this embodiment has at least the following beneficial effects: 1. By finely adjusting the direction of the distal opening, the need for repeated adjustments to the overall position of the endotracheal intubation device during intubation is reduced, thus lowering the complexity of the operation. 2. During intubation, the direction of intubation can be guided according to the position of the glottis, which improves the success rate of endotracheal intubation, especially in difficult airway scenarios. 3. Visual information directly participates in the adjustment of the intubation direction, making the intubation operation more intuitive, reducing reliance on the operator's experience, and reducing the operator's workload; 4. The device structure and system design have good scalability, making it easy to introduce semi-automatic, automatic and intelligent control methods, providing a foundation for subsequent technology upgrades and functional expansion.

[0055] In summary, the endotracheal intubation device in this embodiment can effectively improve the success rate of endotracheal intubation, reduce the difficulty of intubation, and significantly reduce reliance on the operator's experience. This effectively avoids tissue damage to the patient caused by repeated intubation attempts, reduces operational risks, and improves operational safety.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
