Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an anti-dislodgement oropharyngeal airway based on emergency care and airway management. Background Technology

[0002] In emergency medical settings, maintaining a clear airway is a critical prerequisite for ensuring the safety of patients, especially for critically ill patients with impaired consciousness or respiratory failure. Establishing an effective artificial airway in a timely manner can buy time for subsequent treatment and reduce mortality. Airway management, as a core part of the emergency procedure, aims to maintain an open airway and prevent ventilation obstruction caused by tongue retraction, secretion blockage, or airway collapse. Artificial airway assistive devices are important tools for achieving this goal and are widely used in various medical scenarios such as emergency resuscitation, intensive care, and surgical anesthesia.

[0003] Existing airway assist devices still have many shortcomings in practical applications. They lack an effective depth limiting mechanism, making it difficult to accurately control the insertion depth according to the physiological structure of different patients. This can easily lead to problems such as excessively deep insertion that damages the pharyngeal tissue or insufficient insertion that results in low ventilation efficiency. At the same time, the fixation effect is not good. Relying on a single fixation method is not enough to resist the external forces generated by the patient's swallowing, coughing, or agitation. The risk of device displacement and dislodgement is high, affecting the stability of airway patency. Summary of the Invention

[0004] This invention provides an anti-dislodgement oropharyngeal airway based on emergency care and airway management to solve the problems of existing technologies lacking an effective depth limiting mechanism, making it difficult to accurately control the insertion depth according to the physiological structure of different patients, easily leading to excessively deep insertion that damages the pharyngeal tissue or excessively shallow insertion that results in low ventilation efficiency. At the same time, the fixation effect is not good, and relying on a single fixation method is not enough to resist the external forces generated by the patient's swallowing, coughing or agitation, resulting in a high risk of device displacement and dislodgement, which affects the patency and stability of the airway.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A dislodged oropharyngeal airway based on emergency care and airway management includes:

[0007] The ventilation tube body has a limiting plate that is slidably provided along the axial direction on the ventilation tube body. The limiting plate is used to abut against the outside of the patient's oral cavity to limit the insertion depth of the ventilation tube body.

[0008] The fixing assembly includes a second mounting plate disposed on the limiting plate, a support piece rotatably mounted on the second mounting plate, and an elastic element for driving the support piece to unfold and abut against the inner wall of the patient's oral cavity.

[0009] Optionally, the limiting component includes a limiting plate that is slidably mounted on the ventilator body.

[0010] Optionally, the limiting component further includes a limiting slot formed on the vent pipe body. A pair of first mounting plates are fixedly installed on the limiting plate. A limiting plate that cooperates with the limiting slot is slidably installed in the first mounting plate. One end of a first spring is fixedly installed on the limiting plate, and the other end of the first spring is fixedly installed on the first mounting plate. The limiting plate can only move unidirectionally within the limiting slot in cooperation with the first spring.

[0011] Optionally, the fixing component includes a pair of second mounting plates fixedly mounted on the limiting plate. The second mounting plates are provided with mounting grooves, and a support plate is rotatably mounted on the mounting groove. An elastic plate is provided between the support plate and the mounting groove, and the elastic plate is fixedly mounted on the support plate.

[0012] Optionally, the fixing assembly further includes a positioning rod fixedly mounted on the second mounting plate, an insert block slidably mounted on the positioning rod, a second spring fixedly mounted on the insert block, the other end of the second spring being fixedly connected to the second mounting plate, a slot for cooperating with the insert block being provided on the support plate, and a pull rope fixedly mounted on the insert block, the pull rope passing through the limiting plate.

[0013] Optionally, an auxiliary component is provided inside the ventilation tube. The auxiliary component includes a mounting frame fixedly installed inside the ventilation tube body. A miniature camera is provided inside the mounting frame, and a lens is provided on the mounting frame. A liquid-repellent groove is formed on the lens. The miniature camera is wirelessly connected to an external display device.

[0014] Optionally, a first liquid inlet pipe is fixedly installed on the vent pipe body, and a connecting pipe is fixedly installed on the first liquid inlet pipe. The end of the connecting pipe away from the first liquid inlet pipe faces the lens, and a rotating blade is rotatably installed inside it.

[0015] Optionally, the vent pipe body is provided with a lubrication assembly, the lubrication assembly including a second liquid inlet pipe fixedly installed on the vent pipe body, and the vent pipe body having an overflow groove communicating with the second liquid inlet pipe.

[0016] Optionally, the overflow groove is located above the vent pipe body, and the overflow groove is arranged in a ring on the vent pipe body.

[0017] Optionally, the ventilator body is composed of a silicone section and a support section, and a memory metal support mesh is provided inside the silicone section.

[0018] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0019] In the above scheme, the limiting plate is slidably installed on the ventilation tube body, so that the limiting plate can be flexibly adjusted along the axis of the ventilation tube body. The operator can slide and adjust the fixed position of the limiting plate on the ventilation tube body according to different conditions such as the patient's age, oral cavity depth, and condition, thereby accurately controlling the depth of the ventilation tube body inserted into the patient's oral cavity. This breaks the limitations of fixed depth limitation, adapts to the physiological differences of different patients, and ensures that the limiting plate can accurately contact the appropriate part of the patient's oral cavity. This avoids irritation and damage to the throat caused by excessive insertion, while ensuring that the insertion depth meets the effective ventilation requirements, thus improving the versatility and adaptability of the device.

[0020] When the position of the limiting plate needs to be adjusted, the operator pushes the limiting plate along the airway body. At this time, the limiting plate is squeezed by the inner wall of the limiting slot, slides inside the first mounting plate and stretches the first spring. When the limiting plate slides to the target position, the limiting plate is locked into the corresponding limiting slot under the elastic restoring force of the first spring, thus fixing the limiting plate. Since the limiting plate and the first spring can only move in one direction, the limiting plate can only be pushed and adjusted towards the patient's mouth and cannot slide in the opposite direction on its own. This avoids the limiting plate from shifting due to external force or patient movement during the emergency, thereby ensuring the stability of the insertion depth of the airway body. At the same time, the one-way adjustment design also simplifies the operation process. The operator can fix the limiting plate without additional locking structure, improving the efficiency of the emergency operation. Attached Figure Description

[0035] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 8 As shown, an embodiment of the present invention provides an anti-dislodgement oropharyngeal airway based on emergency care and airway management, comprising:

[0037] The ventilation tube body 10 has a limiting plate 21 that is slidably disposed on the ventilation tube body 10 along the axial direction. The limiting plate 21 is used to abut against the outside of the patient's oral cavity to limit the insertion depth of the ventilation tube body 10.

[0038] The fixing component 30 includes a second mounting plate 31 disposed on the limiting plate 21, a support piece 33 rotatably mounted on the second mounting plate 31, and an elastic member for driving the support piece 33 to unfold and abut against the inner wall of the patient's oral cavity.

[0039] The ventilation tube body 10 serves as the core airway channel, providing the patient with a breathing airflow channel and ensuring airway patency during emergency treatment.

[0040] The limiting component 20, through its included limiting plate 21, abuts against the outside of the patient's oral cavity when the ventilation tube body 10 is inserted into the patient's oral cavity, preventing the ventilation tube body 10 from being inserted too deeply, thus avoiding damage to the patient's pharyngeal tissue due to excessive insertion, or problems such as poor airway sealing and easy displacement of the ventilation tube due to shallow insertion.

[0041] The fixing component 30 forms a bidirectional limiting fit with the limiting plate 21 inside the oral cavity, and applies a fixing force to the airway body 10 from inside the oral cavity, which counteracts the tendency of the airway body 10 to shift due to the patient swallowing, coughing or external touch, significantly improves the installation stability of the airway body 10 in the oral cavity, and effectively prevents it from falling off.

[0042] like Figure 1 and Figure 2 As shown, the limiting component 20 includes a limiting plate 21 that is slidably mounted on the vent pipe body 10;

[0043] The limiting plate 21 is slidably installed on the ventilation tube body 10, so that the position of the limiting plate 21 can be flexibly adjusted along the axis of the ventilation tube body 10. The operator can slide and adjust the fixed position of the limiting plate 21 on the ventilation tube body 10 according to the patient's age, oral cavity depth, condition and other different situations, so as to accurately control the depth of the ventilation tube body 10 inserted into the patient's oral cavity. This breaks the limitation of fixed depth limit, adapts to the physiological structure differences of different patients, and ensures that the limiting plate 21 can accurately contact the appropriate part of the patient's oral cavity. This avoids irritation and damage to the throat caused by excessive insertion, and ensures that the insertion depth meets the effective ventilation requirements, thereby improving the versatility and adaptability of the device.

[0044] like Figures 1 to 5 As shown, the limiting component 20 also includes a limiting slot 23 formed on the vent pipe body 10. A pair of first mounting plates 22 are fixedly installed on the limiting plate 21. A limiting plate 24 that cooperates with the limiting slot 23 is slidably installed in the first mounting plate 22. One end of a first spring 25 is fixedly installed on the limiting plate 24. The other end of the first spring 25 is fixedly installed on the first mounting plate 22. The limiting plate 24 can only move unidirectionally within the limiting slot 23 under the cooperation of the first spring 25.

[0045] When the position of the limiting plate 21 needs to be adjusted, the operator pushes the limiting plate 21 to slide along the ventilation tube body 10. At this time, the limiting plate 24 is squeezed by the inner wall of the limiting groove 23, slides inside the first mounting plate 22 and stretches the first spring 25. When the limiting plate 21 slides to the target position, the limiting plate 24 is locked into the corresponding limiting groove 23 under the elastic restoring force of the first spring 25, thus fixing the limiting plate 21. Since the limiting plate 24 and the first spring 25 can only move in one direction, the limiting plate 21 can only be pushed and adjusted towards the direction closer to the patient's mouth and cannot slide in the opposite direction on its own. This avoids the limiting plate 21 from shifting due to external force or patient movement during the emergency, thereby ensuring the stability of the insertion depth of the ventilation tube body 10. At the same time, the one-way adjustment design also simplifies the operation process. The operator can fix the limiting plate 21 without additional locking structure, improving the efficiency of the emergency operation.

[0046] like Figures 1 to 8 As shown, the fixing component 30 includes a pair of second mounting plates 31 fixedly mounted on the limiting plate 21. The second mounting plates 31 are provided with mounting grooves 32. A support piece 33 is rotatably mounted on the mounting grooves 32. An elastic piece 34 is provided between the support piece 33 and the mounting grooves 32. The elastic piece 34 is fixedly mounted on the support piece 33.

[0047] Once the airway body 10 is inserted to the target depth, the support piece 33 rotates out of the mounting groove 32 under the action of the elastic piece 34, unfolds towards the inner wall of the patient's mouth and abuts against the inner wall of the mouth. The support pieces 33 on a pair of second mounting plates 31 form a symmetrical support structure. Through the friction and contact pressure between the support piece and the inner wall of the mouth, the airway body 10 is limited and fixed from the inside of the mouth. Combined with the limiting effect of the limiting plate 21 outside the mouth, a two-way fixation is formed, which effectively prevents the airway body 10 from axially shifting or falling off when the patient swallows, coughs or moves their head. At the same time, the elastic support design of the elastic piece 34 can adapt to the size of the space inside the mouth of different patients, avoiding excessive support force that could damage the oral mucosa.

[0048] like Figure 7 As shown, the fixing assembly 30 also includes a positioning rod 37 fixedly installed on the second mounting plate 31. A plug 35 is slidably installed on the positioning rod 37. A second spring 38 is fixedly installed on the plug 35. The other end of the second spring 38 is fixedly connected to the second mounting plate 31. A slot 36 that mates with the plug 35 is provided on the support plate 33. A pull rope 39 is fixedly installed on the plug 35. The pull rope 39 passes through the limiting plate 21.

[0049] After the ventilation tube body 10 is inserted to the designated depth, the operator pulls the insertion block 35 along the positioning rod 37 by pulling the rope 39, compressing the second spring 38, so that the insertion block 35 disengages from the slot 36 on the support plate 33. At this time, the support plate 33 can rotate freely under the action of the elastic plate 34. The support plate 33 unfolds under the action of the elastic plate 34 and abuts against the inner wall of the oral cavity to form a limiting fixation. After the device is used, the support plate 33 is reset and the insertion block 35 is reinserted into the slot 36 for easy use next time.

[0050] like Figure 3 As shown, an auxiliary component is provided inside the ventilation tube. The auxiliary component 40 includes a mounting frame 41 fixedly installed inside the ventilation tube body 10. A miniature camera 42 is provided inside the mounting frame 41. A lens 43 is provided on the mounting frame 41. A liquid-repellent groove 44 is provided on the lens 43. The miniature camera 42 is wirelessly connected to an external display device.

[0051] The mounting frame 41 provides a stable mounting carrier for the miniature camera 42 and lens 43, ensuring their fixed position within the airway body 10 and preventing displacement due to movement of the airway body 10 or patient movements. The miniature camera 42 is built into the airway body 10 and is inserted into the patient's mouth along with the airway body 10, capturing real-time images of the airway interior, including the pharyngeal structure, the location of the airway port, and whether there is any obstruction by secretions. The lens 43 protects the lens of the miniature camera 42, preventing secretions and saliva in the airway from directly contaminating the lens and affecting image clarity. The phlegm-repellent groove 44 is used to remove secretions and saliva. The miniature camera 42 transmits the captured images to an external display device in real time via wireless transmission technology. Operators can visually observe the airway interior through the display device, accurately determine whether the insertion position of the airway body 10 is accurate, whether the airway is unobstructed, and promptly detect and address issues such as secretion obstruction, avoiding ventilation failure or airway damage caused by blind operation, and significantly improving the accuracy and safety of airway management during emergency treatment.

[0052] like Figures 2 to 4 As shown, a first liquid inlet pipe 45 is fixedly installed on the vent pipe body 10, and a connecting pipe 46 is fixedly installed on the first liquid inlet pipe 45. The end of the connecting pipe 46 away from the first liquid inlet pipe 45 faces the lens 43, and a rotating blade 47 is rotatably installed inside it.

[0053] When the lens 43 becomes contaminated with secretions and saliva from the airway, affecting the clarity of the miniature camera 42, the operator injects cleaning fluid (such as sterile saline) through the first inlet tube 45. The cleaning fluid flows into the connecting tube 46 through the first inlet tube 45. Under the impact of the flowing cleaning fluid, the rotating blade 47 inside the connecting tube 46 rotates. The rotating blade 47 disperses the cleaning fluid into uniform droplets or streams, which are evenly sprayed onto the surface of the lens 43. The cleaning fluid washes away the dirt on the surface of the lens 43. At the same time, the rotating blade 47 enhances the contact and friction between the cleaning fluid and the surface of the lens 43, improving the cleaning effect, quickly removing contaminants from the lens 43, and restoring the transparency of the lens 43. Meanwhile, the drainage groove 44 also facilitates the drainage of the cleaning fluid, ensuring that the miniature camera 42 can always capture clear airway images, ensuring the continuous reliability of the auxiliary observation function, avoiding misjudgment by the operator due to the blurriness of the lens 43, and further improving the safety and effectiveness of emergency operations.

[0054] like Figures 1 to 3 As shown, a lubrication assembly 50 is provided on the vent pipe body 10. The lubrication assembly 50 includes a second liquid inlet pipe 51 fixedly installed on the vent pipe body 10. An overflow groove 52 communicating with the second liquid inlet pipe 51 is provided on the vent pipe body 10. The overflow groove 52 is located above the vent pipe body 10 and is arranged in a ring on the vent pipe body 10.

[0055] Before the airway body 10 is inserted into the patient's mouth, the operator injects lubricant (such as medical lubricating gel) through the second inlet tube 51. The lubricant flows into the overflow groove 52 through the second inlet tube 51. Since the overflow groove 52 is connected to the outside of the airway body 10, the lubricant overflows evenly from the overflow groove 52 to the outer surface of the airway body 10, forming a lubricating film between the airway body 10 and the patient's oral mucosa. This lubricating film can significantly reduce the friction between the airway body 10 and the oral mucosa when it is inserted and removed, avoiding damage and pain to the oral mucosa caused by excessive friction, improving the patient's comfort, and making the insertion and removal of the airway body 10 smoother, reducing the difficulty of operation for the operator, reducing operation time, and buying valuable time for emergency treatment.

[0056] like Figure 1 and Figure 2 As shown, the ventilator body 10 is composed of a silicone section 101 and a support section 102, and a memory metal support mesh is provided inside the silicone section 101.

[0057] The silicone segment 101 of the airway body 10 is made of silicone material. Silicone has good biocompatibility and softness, which can reduce irritation and the risk of mucosal damage when in contact with the patient's oral mucosa and pharyngeal tissues, thus improving the patient's comfort. The support segment 102 provides structural support for the airway body 10, ensuring the patency of the airway and preventing the airway body 10 from collapsing due to external pressure or the patient's swallowing. The memory metal support mesh set inside the silicone segment 101 utilizes the elasticity and shaping ability of memory metal, allowing the silicone segment 101 to quickly recover its original shape after being squeezed by external force, thus preventing airway obstruction. It also enhances the structural strength of the silicone segment 101, preventing excessive deformation. At the same time, the flexibility of the memory metal support mesh does not affect the overall softness of the silicone segment 101, achieving a balance between comfort and structural stability. This ensures that the airway body 10 maintains an open airway throughout the emergency process, providing stable respiratory support for the patient.

[0058] The working process of the anti-dislodgement oropharyngeal airway based on emergency care and airway management provided by this invention is as follows:

[0059] Before operation, lubricant is injected into the overflow groove 52 through the second inlet pipe 51 of the lubrication component 50. The annular overflow groove 52 ensures that the lubricant evenly covers the outer surface of the upper part of the ventilation tube body 10, forming a lubricating layer between the ventilation tube body 10 and the oral mucosa, reducing frictional damage during insertion and improving the smoothness of operation. At the same time, the silicone section 101 of the ventilation tube body 10, with its soft properties and the shaping ability of the internal memory metal support mesh, can adapt to the physiological curves of the patient's oral cavity and pharynx, while the support section 102 ensures that the airway does not collapse, laying the foundation for subsequent insertion and ventilation.

[0060] Based on individual differences in the depth of the patient's oral cavity, the limiting plate 21 of the sliding limiting component 20 is adjusted along the ventilation tube body 10. During adjustment, the limiting plate 24 stretches the first spring 25 under the compression of the limiting slot 23. After sliding to the target position, the first spring 25 resets and pushes the limiting plate 24 into the slot, thereby achieving unidirectional fixation of the limiting plate 21 and accurately controlling the insertion depth of the ventilation tube body 10 to avoid damage from excessive depth or displacement from excessive shallow depth.

[0061] The ventilation tube body 10 is slowly inserted into the patient's mouth. After insertion, the support piece 33 of the fixing component 30 unfolds under the action of the elastic piece 34 and contacts the inner wall of the patient's mouth. Inserting the support piece 33 into the slot 36 can reset the support piece 33 for easy use next time. At this time, the limiting plate 21 limits it externally, and the support piece 33 abuts internally, forming a two-way fixation, which effectively resists the external force generated by the patient's swallowing and coughing, and prevents the ventilation tube body 10 from falling off.

[0062] During insertion, the miniature camera 42 of the auxiliary component 40 is fixed inside the airway body 10 by the mounting frame 41, and captures real-time images of the airway interior. The images are then wirelessly transmitted to an external display device. The operator can use the clear images protected by the lens 43 to determine whether the airway port is aligned with the airway and whether there is any blockage by secretions. If the lens 43 is stained, cleaning fluid is injected through the first liquid inlet pipe 45. As the cleaning fluid flows through the connecting pipe 46, it drives the rotating blade 47 to rotate, dispersing the cleaning fluid and evenly rinsing the lens 43, quickly restoring the clarity of the image and ensuring accurate observation.

[0063] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
