Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and particularly relates to an oropharyngeal airway that can perform airway anesthesia. Background Art

[0002] Airway anesthesia, especially bronchial anesthesia, is an anesthetic method using tracheal intubation as a means. Airway anesthesia usually involves tracheal intubation. During this process, anesthesiologists will administer local anesthetic drugs to reduce the stimulatory response of the larynx and trachea. After tracheal intubation, the anesthetic drugs can be administered by spraying, inhalation, or by connecting the tracheal intubation to an anesthesia machine for delivery, etc., to achieve airway control and pain relief during the operation. This anesthetic method requires experienced anesthesiologists to implement and monitor to ensure the safety of patients.

[0003] When performing airway anesthesia operations, it is usually necessary to use devices such as an oropharyngeal airway or a laryngoscope to open the patient's mouth. Among them, a laryngoscope is a precision device specifically designed for examining the laryngeal structure, diagnosing diseases, and assisting in treatment. It usually consists of a light source, a lens, an operating handle, and a connecting tube, etc., aiming to provide clear and detailed images of the larynx to help doctors make accurate diagnoses and treatments. The oropharyngeal airway is a simple, effective, economical, and fast method to maintain airway patency. It is mainly used for comatose patients or patients after general anesthesia recovery to prevent the posterior displacement of the tongue root from blocking the airway. At the same time, it is beneficial for sputum suction and maintaining airway patency. Both the laryngoscope and the oropharyngeal airway are designed in a curved shape to fit the patient's oropharynx and larynx.

[0004] Currently, most of the existing oropharyngeal airways are integrally formed. When in use, they are only limited to selecting a suitable model according to the patient's body type. However, due to the complexity of the oropharynx of different patients, the oropharyngeal airway still cannot accurately fit the patient's oropharynx during use, resulting in certain limitations in use. Moreover, the scope of use is only limited to preventing the posterior displacement of the patient's tongue root from blocking the airway. Since the oropharyngeal airway is usually placed in the patient's oropharynx, it cannot contact the epiglottis above the airway and does not have the effect of opening the patient's epiglottis, with poor auxiliary effect and low practicality. As a result, during subsequent treatment processes, if a series of operations such as urgently performing airway anesthesia or airway intubation on the patient are required, it is necessary to remove the oropharyngeal airway again and use a laryngoscope to perform repeated intubation operations, causing a certain degree of damage to the patient's oropharynx and larynx. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an oropharyngeal airway that can perform airway anesthesia, so as to fundamentally solve the problems that most of the existing oropharyngeal airways adopt an integrally formed design, resulting in certain limitations in use and poor auxiliary effect and low practicality.

[0006] An oropharyngeal airway that can perform airway anesthesia according to an embodiment of the present invention includes a mask assembly, an intubation assist member penetrating through the middle of the mask assembly, an oropharyngeal airway assembly at least partially embedded in the intubation assist member, and a binding strap provided on one side of the mask assembly close to the oropharyngeal airway assembly; The oropharyngeal airway assembly includes a buckling component provided at the top for connecting the intubation assist member, a handheld portion provided at the bottom of the buckling component, an insertion portion extending outward from the handheld portion away from the buckling component, a curvature adjustment portion embedded in the middle section of the insertion portion and separating the insertion portion into two parts, and an epiglottis abutting end movably embedded on the side of the insertion portion away from the handheld portion; The buckling component includes a buckling wall embedded in the intubation assist member, at least four elastic buckles embedded at the periphery of the buckling wall, a first linkage belt and a second linkage belt oppositely arranged and embedded on the inner side of the buckling wall. The first linkage belt is provided between the intubation assist member and the curvature adjustment portion, and the second linkage belt is provided between the intubation assist member and the epiglottis abutting end; Wherein, the first linkage belt and the second linkage belt can be sequentially pulled or pushed through the intubation assist member to move, so that the curvature adjustment portion driven by the first linkage belt extends and retracts based on the middle section of the insertion portion to adjust the curvature of the insertion portion, and the epiglottis abutting end driven by the second linkage belt moves towards or away from the patient's epiglottis.

[0007] Further, the buckling component further includes limiting sleeves respectively sleeved on the outer surfaces of the first linkage belt and the second linkage belt for limiting, and positioning bolts inserted along the buckling wall towards the first linkage belt and the second linkage belt respectively.

[0008] Further, the intubation assist member includes mask buckles clamped on both sides of the mask assembly, a fixing portion provided between the two mask buckles, a docking component provided on the side of the fixing portion close to the oropharyngeal airway assembly and connected to the buckling component, at least two adjustment knobs movably provided on the side of the fixing portion away from the docking component for driving the first linkage belt and the second linkage belt, and a pipeline guiding component provided on the side of the adjustment knob away from the fixing portion.

[0009] Further, the docking component includes a docking portion for accommodating the buckling component, at least two oral positioning portions extending outward from the outer surface of the docking portion, and a docking groove embedded on the inner side of the docking portion and adapted to the elastic buckles.

[0010] Further, the pipeline guiding component includes a catheter placement portion for accommodating a catheter, and a pipeline limiting member movably embedded in the catheter placement portion for guiding the insertion position of the catheter.

[0011] Further, the pipeline position limiter includes an adjustment shaft, a driving gear axially and fixedly connected to the adjustment shaft, a fixed sleeve rod disposed on a side of the driving gear away from the adjustment shaft, an extension portion extending outward circumferentially along the fixed sleeve rod, and a limiting end disposed on a side of the extension portion away from the fixed sleeve rod. Wherein, the driving gear can be driven by the adjustment shaft to slide along an inner track of the catheter placement portion, so as to push and embed a catheter inside the catheter placement portion to adjust the catheter placement position.

[0012] Further, the limiting end is formed by two semi-cylindrical sleeves oppositely arranged circumferentially to fit the outer shapes of the catheters on both sides. A plurality of rollers are embedded on opposite sides of the two limiting ends for guiding the insertion of the catheter.

[0013] Further, an arc-shaped groove for accommodating the curvature adjustment portion is formed in a middle section of the insertion portion. The curvature adjustment portion can move along a track of the arc-shaped groove. The curvature adjustment portion is fixedly connected to an inner wall of a bottom of the insertion portion, and the first linkage belt is fixedly connected to the curvature adjustment portion through a rack fixing bolt. Wherein, when the curvature adjustment portion is driven to move by the first linkage belt, the insertion portion located at the bottom can be pulled by the curvature adjustment portion to bend towards or away from the insertion portion at the top.

[0014] Further, a side of the second linkage belt away from the buckling assembly is fixedly connected to the inside of the epiglottis abutting end through the rack fixing bolt.

[0015] Compared with the prior art: The oropharyngeal airway tube capable of performing airway anesthesia in the above embodiments of the present invention can sequentially pull or push the first linkage belt and the second linkage belt to move through the intubation auxiliary member, so that the curvature adjustment portion is driven by the first linkage belt to extend and contract based on the middle section of the insertion portion to realize the curvature adjustment of the insertion portion, and the epiglottis abutting end is driven by the second linkage belt to move towards or away from the patient's epiglottis, so as to improve the adaptability between the oropharyngeal airway tube assembly and the patient's oropharynx. At the same time, the opening of the patient's epiglottis can also assist in subsequent sputum suction, airway anesthesia or intubation operations on the patient. The process does not require repeated insertion and extraction of the oropharyngeal airway tube assembly, which improves the protection of the patient and the practicability of the present invention, and solves the problem that most of the current oropharyngeal airway tubes adopt an integrally formed design, resulting in certain limitations in use and poor auxiliary effect and low practicality.

[0022] Please refer to Figures 1 to 11 , which shows an oropharyngeal airway tube capable of airway anesthesia in an embodiment of the present invention, including a mask assembly 1, an intubation assist member 2 penetrating through the middle of the mask assembly 1, an oropharyngeal airway tube assembly 3 at least partially embedded in the intubation assist member 2, and a binding strap 4 provided on one side of the mask assembly 1 close to the oropharyngeal airway tube assembly 3. The oropharyngeal airway tube assembly 3 includes a fastening assembly 32 provided at the top for connecting the intubation assist member 2, a hand-held portion 31 provided at the bottom of the fastening assembly 32, an insertion portion 33 extending outward from the hand-held portion 31 away from the fastening assembly 32, a curvature adjustment portion 34 embedded in the middle section of the insertion portion 33 and separating the insertion portion 33 into two parts, and an epiglottis abutting end 35 movably embedded in the insertion portion 33 away from the hand-held portion 31. The fastening assembly 32 includes a fastening wall 321 embedded in the intubation assist member 2, at least four elastic buckles 322 embedded in the perimeter of the fastening wall 321, a first linkage belt 325 and a second linkage belt 326 oppositely arranged and embedded inside the fastening wall 321. The first linkage belt 325 is provided between the intubation assist member 2 and the curvature adjustment portion 34, and the second linkage belt 326 is provided between the intubation assist member 2 and the epiglottis abutting end 35.

[0023] Furthermore, the snap - connection assembly 32 further includes a limiting sleeve 324 sleeved on the outer surfaces of the first linkage belt 325 and the second linkage belt 326 respectively for limiting, and a positioning bolt 323 inserted along the snap - connection wall 321 towards the first linkage belt 325 and the second linkage belt 326 respectively. The intubation auxiliary part 2 includes a face - mask buckle plate 21 clamped on both sides of the face - mask assembly 1, a fixing part 22 arranged between the two face - mask buckle plates 21, a docking assembly arranged on the fixing part 22 towards the side close to the oropharyngeal airway assembly 3 and connected to the snap - connection assembly 32, at least two adjusting knobs 26 movably arranged on the side of the fixing part 22 away from the docking assembly for driving the first linkage belt 325 and the second linkage belt 326, and a pipeline guiding assembly arranged on the side of the adjusting knob 26 away from the fixing part 22. The docking assembly includes a docking part 23 for accommodating the snap - connection assembly 32, at least two oral positioning parts 24 extending outwards along the outer surface of the docking part 23, and a docking groove 25 embedded in the inner side of the docking part 23 and adapted to the spring buckle 322. The pipeline guiding assembly includes a catheter - accommodating part 27 for accommodating the catheter, and a pipeline limiting part 28 movably embedded in the catheter - accommodating part 27 for guiding the insertion position of the catheter. The pipeline limiting part 28 includes an adjusting shaft 281, a driving tooth 282 axially and fixedly connected to the adjusting shaft 281, a fixed sleeve rod 283 arranged on the side of the driving tooth 282 away from the adjusting shaft 281, an extension part 284 extending outwards along the circumferential direction of the fixed sleeve rod 283, and a limiting end 285 arranged on the side of the extension part 284 away from the fixed sleeve rod 283. Among them, the driving tooth 282 can be driven by the adjusting shaft 281 to slide along the inner - side track of the catheter - accommodating part 27, so as to push the catheter embedded in the inner side of the catheter - accommodating part 27 to adjust the catheter insertion position. The outer shape of the limiting end 285 is formed by two semi - cylinders arranged circumferentially opposite to each other to fit the outer shapes of the two sides of the catheter. A plurality of rollers 286 are embedded on the opposite side of the two limiting ends 285. An arc - shaped groove for accommodating the curvature - adjusting part 34 is provided in the middle section of the insertion part 33. The curvature - adjusting part 34 can move along the track of the arc - shaped groove. The curvature - adjusting part 34 is fixedly connected to the bottom inner wall of the insertion part 33, and the first linkage belt 325 is fixedly connected to the curvature - adjusting part 34 through a rack fixing bolt 36. Among them, when the curvature - adjusting part 34 is driven to move by the first linkage belt 325, the insertion part 33 at the bottom can be pulled by the curvature - adjusting part 34 to bend towards or away from the insertion part 33 at the top. The side of the second linkage belt 326 away from the snap - connection assembly 32 is fixedly connected to the inside of the epiglottis abutting end 35 through a rack fixing bolt 36.

[0024] In specific implementation, the intubation auxiliary part 2 is in an unadjusted state and is consistent with the conventional dimensions of the existing oropharyngeal airway. As can be understood by those skilled in the art, during operation, medical staff can select a suitable model of the oropharyngeal airway assembly 3 according to the patient's height, weight, and anatomical characteristics in accordance with the conventional intubation method, and assist the patient to lie flat on the back with the head tilted backward to keep the three axes of the upper respiratory tract (mouth, pharynx, larynx) as much as possible on the same straight line. Then, moisten the oropharyngeal tube, turn the pharyngeal curved part of the oropharyngeal tube towards the patient's mandible, and insert it into the oral cavity along the tongue towards the palate. When the top of the airway approaches the posterior wall of the oropharynx (after passing through the uvula), rotate the airway 180° so that its concave surface faces downward, and then, taking advantage of the patient's inhalation, push the airway downward to make the lower part of its curved part press on the root of the tongue and the upper part against the posterior wall of the oropharynx. After confirming that the position of the oropharyngeal airway is appropriate and the air flow is unobstructed, dock the fastening component 32 of the oropharyngeal airway assembly 3 with the intubation auxiliary part 2. Specifically, medical staff can first remove the positioning bolt 323 on the fastening wall 321 to make the first linkage belt 325 and the second linkage belt 326 fixed by the positioning bolt 323 in a loose and adjustable state, and then sequentially guide the first linkage belt 325 and the second linkage belt 326 to be inserted into the corresponding rack sleeves on the inner wall of the docking part 23 up and down. It should be noted that, such as Figure 2As shown, a rack sleeve corresponding to the position and size of the limit sleeve 324 is arranged at the upper and lower positions inside the docking part 23. Among them, a buckling rack adapted to the first linkage belt 325 and the second linkage belt 326 is arranged inside the rack sleeve. And the two groups of buckling racks are respectively connected to the adjusting knob 26, and the buckling racks are wound through the adjusting knob 26. In some alternative embodiments, the connection modes of the buckling racks with the first linkage belt 325 and the second linkage belt 326 can be fish-tail splicing. As shown in Figure 6, and both the first linkage belt 325 and the second linkage belt 326 are strip structures made of steel material, which have good structural support to ensure the stability of the insertion part 33 and the epiglottis abutting end 35 during the adjustment process. It should be further noted that, due to a certain angular difference between the first linkage belt 325 and the second linkage belt 326 corresponding to the axial directions of the two adjusting knobs 26, the rack sleeve on the inner wall of the docking part 23 can adopt a spiral path extending along the axial direction of the adjusting knob 26, so that during the subsequent process of the adjusting knob 26 driving the first linkage belt 325 and the second linkage belt 326 to wind up, the winding direction can be adjusted to realize the winding operation of the linkage belt along the axial direction of the adjusting knob 26. After that, the medical staff can relatively pinch the intubation auxiliary part 2 and the oropharyngeal airway assembly 3, and make the snap buckle 322 embedded in the docking groove 25 inside the docking part 23 to complete the assembly of the intubation auxiliary part 2 and the oropharyngeal airway assembly 3 to wait for the subsequent tracheal intubation operation. In some alternative embodiments, the medical staff can fix the intubation auxiliary part 2 and the oropharyngeal airway assembly 3 with medical tape, or install a mask assembly 1 on the intubation auxiliary part 2 and fix it with the binding strap 4 on the mask assembly 1 to the patient's head. Among them, the binding strap 4 can be a design of elastic band plus magic tape buckle to facilitate adapting to different patient head diameters.

[0025] Further, by fine-tuning the oropharyngeal airway assembly 3 through the intubation auxiliary part 2, the adaptability of the oropharyngeal airway assembly 3 to the patient's oropharynx is improved. When subsequent medical staff perform sputum suction operations or airway intubation and airway anesthesia operations on the patient according to the patient's condition, auxiliary operations during the intubation process are realized. Specifically, medical staff can determine the length of the insertion part 33 exposed on the periphery of the oropharyngeal airway assembly 3 after it enters the patient's oropharynx, as well as the tightness during the insertion of the oropharyngeal airway assembly 3. For example, if the length of the insertion part 33 exposed outside after insertion into the oropharynx meets the requirements, but it still feels loose during the insertion process, and continuous insertion may cause damage to the patient's oropharynx. Therefore, medical staff can rotate the uppermost adjustment knob 26 clockwise to drive the buckle rack and the first linkage belt 325 to wind along their axial directions in sequence. It should be noted that a winding disc with the same outer diameter as the adjustment knob 26 is arranged in the axial direction of the adjustment knob 26, and the inside of the winding disc is hollow to facilitate subsequent intubation operations. The winding discs on the two adjustment knobs 26 are stacked towards the fixing part 22. To avoid mutual influence during their rotation, the diameter of the adjustment knob 26 and the corresponding winding disc closer to the fixing part 22 is smaller than that of the other adjustment knob 26. As Figure 10 and Figure 11 shown, while the two do not affect each other, the winding and unwinding operations of the first linkage belt 325 and the second linkage belt 326 are realized. During the process, the curvature adjustment part 34 will move along the arc-shaped groove track inside the insertion part 33 to realize the adjustment of the middle curvature of the insertion part 33. It can be understood that the insertion part 33 can be bent towards or away from its oropharyngeal position to improve the fitting degree between the insertion part 33 and the patient's oropharynx and ensure its applicability. Immediately afterwards, when medical staff need to perform sputum suction, airway anesthesia, or intubation operations on the patient, they can rotate the other adjustment knob 26 to realize the winding adjustment of the second linkage belt 326, and drive the epiglottis abutting end 35 to move towards or away from the patient's epiglottis through the second linkage belt 326. It can be understood that the patient's epiglottis is pushed open. Among them, it should be noted that the epiglottis is located at the lower part of the patient's pharynx, and during sputum suction, airway anesthesia, or intubation operations, the epiglottis needs to be propped open to expose the patient's trachea for corresponding operations. Therefore, the existing operation method usually involves removing the oropharyngeal airway and then performing a secondary insertion through a laryngoscope, and the above-mentioned multiple operations are extremely likely to cause damage to the mucous membrane of the patient's oropharynx and larynx, resulting in severe discomfort for the patient after the operation. Therefore, in this application, by adjusting the epiglottis abutting end 35, the effect of assisting the epiglottis to open is realized from the inside, thereby reducing the damage caused to the patient by the repeated insertion of subsequent laryngoscopes or other auxiliary devices. After that, medical staff can directly insert the corresponding catheter into the patient's trachea along the catheter placement part 27 to perform operations such as sputum suction, airway anesthesia, or intubation.

[0026] In addition, in some optional embodiments of the present invention, a pipe limiter 28 can be further provided in the tube placement portion 27, and the pipe limiter 28 can be used to assist in guiding the insertion position of the catheter during the subsequent intubation process, and to limit the position of the pipe after insertion. Specifically, the medical staff can rotate the adjustment shaft 281 after inserting the catheter into the tube placement portion 27 according to the current outer diameter of the catheter, so as to drive the driving gear 282, the fixed sleeve rod 283, the extension portion 284 and the limiting end 285 to slide laterally along the catheter hole track opened on the tube placement portion 27 in turn. During the process, the inner catheter can be pushed toward the edge of the catheter hole to limit the surface of the catheter and ensure the accuracy of intubation. While ensuring accuracy, it also ensures the stability of the tube retained in the patient's body after subsequent intubation. At the same time, medical staff can also fine-tune the insertion direction of the catheter during the insertion process through the tube limiter 28. For example, during the process of guiding the catheter into the patient's bronchus, medical staff usually pressurize the catheter in the direction of the bronchus on the side to be inserted based on experience during the operation to achieve the purpose of guiding the catheter to change the insertion trajectory. The accuracy is low and it is very easy to damage the patient's trachea. There are certain operational risks. The present application ensures the accuracy of the intubation process to a great extent. It can be understood that the catheter is inserted in the right position, and at the same time it can limit the catheter to ensure the stability of the retained pipeline.

[0027] In summary, the oropharyngeal airway capable of performing airway anesthesia in the above-mentioned embodiment of the present invention can sequentially pull or push the first linkage belt 325 and the second linkage belt 326 to move through the intubation auxiliary part 2, so that the curvature adjustment part 34 driven by the first linkage belt 325 can adjust the curvature of the insertion part 33 based on the extension and telescoping of the middle section of the insertion part 33, and the epiglottis abutting end 35 driven by the second linkage belt 326 can move toward or away from the patient's epiglottis, so as to improve the adaptability of the oropharyngeal airway assembly 3 to the patient's oropharynx. At the same time, stretching the patient's epiglottis can also assist in subsequent suctioning, airway anesthesia or intubation operations on the patient. There is no need to repeatedly pull out and plug in the oropharyngeal airway assembly 3 during the process, which improves the protection of the patient and improves the practicality of the present invention. It solves the problem that most current oropharyngeal airways adopt an integrated molding design, resulting in certain usage limitations, poor auxiliary effects and low practicality.
