Description

Technical Field

[0001] The present invention relates to the technical field of intubation anesthesia, and particularly to an intubation anesthesia assistance device. Background Art

[0002] Intubation anesthesia refers to a method of anesthesia in which, during general anesthesia, in order to maintain the respiratory function of a patient and ensure that the patient does not experience airway obstruction or respiratory depression, tracheal intubation is performed. During the tracheal intubation operation, it is necessary to first use a laryngoscope to open the patient's mouth, then insert the tracheal tube into the patient's trachea, and finally supply oxygen to the patient through the tracheal tube.

[0003] During actual operation, after the operator uses the laryngoscope to open the patient's mouth, the operator needs to hold the laryngoscope with one hand and then insert the tracheal tube with the other hand. After the tracheal tube is inserted, the operator holds both the tracheal tube and the laryngoscope with one hand and arranges the bite block with the other hand. After the bite block is arranged, the laryngoscope is withdrawn, and then the operator holds both the intubation tube and the bite block with one hand and uses the other hand to complete: inflating the tracheal tube, auscultating the patient's lungs and chest, and tying and fixing the tracheal tube and the bite block; the above process requires a high level of proficiency from the operator, and in the actual operation process, since most actions can only be completed with one hand, it is easy to make mistakes. Prolonged single-handed operation is not only laborious but also affects the stability of the operator's hand, thereby affecting the patient's comfort and the efficiency of tracheal intubation. Therefore, in order to improve the efficiency of tracheal intubation and the convenience of the operator, the present invention provides an intubation anesthesia assistance device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intubation anesthesia assistance device. By setting a positioning component, it can not only assist the operator in holding and fixing the laryngoscope and the tracheal tube, so that the operator does not need to always hold the laryngoscope and the tracheal tube with hands, improving the convenience of the operator when performing other operations, but also assist the operator in opening the patient's mouth, and the size of the opened patient's mouth can be quickly adjusted. This can not only improve the operator's surgical field of view but also increase the success rate during the insertion of the tracheal tube. In addition, the positioning component can automatically achieve the fixation effect of the tracheal tube, thereby further reducing the difficulty of the surgical operation and improving the efficiency of the operator. Through the above settings, the problems of low efficiency and high operation difficulty during the current tracheal intubation operation process can be solved.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: An intubation anesthesia assistance device includes a bottom plate. A limit plate is fixedly connected to the top of the bottom plate. An airbag is inserted into the limit plate. Neck positioning plates and shoulder positioning plates are symmetrically installed on the top of the bottom plate; a positioning assembly is used to assist the operator in arranging the tracheal intubation and laryngoscope, and the positioning assembly is connected to the neck positioning plate.

[0006] Optionally, the positioning assembly includes a first pull rod and a second pull rod inserted on the neck positioning plate. One end of the first pull rod is clamped with a first support rod, and one end of the second pull rod is clamped with a second support rod. A first arc-shaped plate is fixedly connected to the first support rod, and a second arc-shaped plate is fixedly connected to the second support rod.

[0007] Optionally, a neck pad is fixedly connected to one end of the airbag close to the neck positioning plate. An air inlet and an air outlet are respectively arranged on both sides of the airbag. The neck pad has a circular arc-shaped contour that bulges upward, and the airbag and the neck pad are integrally manufactured and connected to each other.

[0008] Optionally, the shoulder positioning plate has a circular arc-shaped contour. A first bending part is installed at the middle position of the neck positioning plate, and a second bending part is installed on the top of the neck positioning plate.

[0009] Optionally, the first bending part has an inwardly concave contour, and the second bending part has an outwardly convex contour. A straight chute and a limit groove are successively opened in the second bending part from top to bottom. A plurality of protrusions are arranged at the top of the limit groove.

[0010] Optionally, S-shaped bent rods are fixedly connected to one ends of the first pull rod and the second pull rod close to the neck positioning plate. The contour of the S-shaped bent rod is in the shape of "S". A weakening groove is opened on the S-shaped bent rod, and the S-shaped bent rod is thinned by the weakening groove.

[0011] Optionally, clamping heads are fixedly connected to the other ends of the first pull rod and the second pull rod. Clamping grooves are opened at the middle positions of the first support rod and the second support rod. The first pull rod and the first support rod and the second pull rod and the second support rod are fixed to each other through the clamping heads, and the size of the clamping head matches the size of the clamping groove.

[0012] Optionally, a first arc-shaped plate is fixedly connected to the first support rod, and a second arc-shaped plate is fixedly connected to the second support rod. The first support rod and the first arc-shaped plate and the second support rod and the second arc-shaped plate are fixed to each other through elastic bent rods. The first support rod and the second support rod both have a "C" - shaped contour, and bent rods that bend inward are fixedly connected to both ends of the first support rod and the second support rod.

[0013] Optionally, insertion parts are fixedly connected to both ends of the first arc-shaped plate, and out-turned parts are fixedly connected to both ends of the second arc-shaped plate. The out-turned parts have a contour of turning outwards, and slots matching the size of the insertion parts are formed in the out-turned parts.

[0014] Optionally, C-shaped bent plates are fixedly connected to both the first support rod and the second support rod. The C-shaped bent plates have a "C" - shaped contour, and the elastic bent rod is a curved surface elastic structure.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the positioning assembly, it can assist the operator in holding and fixing the laryngoscope and the tracheal intubation, so that the operator does not need to hold the laryngoscope and the tracheal intubation with hands all the time, improving the convenience when the operator performs other operations. The positioning assembly can assist the operator in opening the patient's mouth, and the size of the opened patient's mouth can be quickly adjusted. This can not only improve the operator's surgical field of vision, but also improve the success rate during the insertion process of the tracheal intubation. At present, after the tracheal intubation is inserted, a bite block is needed to protect the tracheal intubation. In this application, the setting of the positioning assembly not only eliminates the bite block, but also can automatically achieve the fixing effect of the tracheal intubation, thereby further reducing the difficulty of the surgical operation and improving the efficiency of the operator.

[0016] By setting the S-shaped bent rod, the straight chute and the limiting groove, the S-shaped bent rod is respectively inserted through the straight chute and the limiting groove on the neck positioning plate from top to bottom. Such a staggered insertion structure enables the S-shaped bent rod to be limited by the straight chute and the limiting groove, preventing the S-shaped bent rod from being misaligned and disengaged during the sliding process on the neck positioning plate. The cooperation of the S-shaped bent rod, the straight chute and the limiting groove enables the first pull rod and the second pull rod to be assembled with the neck positioning plate, and both the first pull rod and the second pull rod can slide on the neck positioning plate, with good stability and convenient operation during the sliding process.

[0017] By setting a first support rod and a second support rod, the operator can use the first support rod and the second support rod to open the patient's mouth, and at the same time, with the help of the cooperation of the S-shaped bent rod and the neck positioning plate, adjust the distance between the first support rod and the second support rod, thereby changing the size of the patient's mouth that is opened. This way of opening will not only not affect the tissues inside the patient's mouth, but also will not block any field of view inside the patient's mouth, thereby ensuring the efficiency of the operator when performing tracheal intubation on the patient. Since the first support rod and the second support rod are disassembled and assembled structures, during actual use, the operator can choose the size of the first support and the second support rod according to the patient's own situation to adapt to more patients. The angles of the first support rod and the second support rod can be adjusted by manual bending, so that they can better adapt to the patient's oral contour, improving the patient's comfort while also improving the support and opening effect of the patient's mouth.

[0018] By providing the first curved plate and the second curved plate, the operator can fix the tracheal tube with the help of the first curved plate and the second curved plate after inserting the tracheal tube into the patient's body, thereby eliminating the need for the operator to manually hold the tracheal tube, and the first support rod and the second support rod can prop up and open the patient's mouth, so when holding and fixing the tracheal tube, the patient's teeth will not bite the tracheal tube, thereby eliminating the dental pad currently used and saving medical costs. By providing the elastic bent rod, the shaking and pulling generated when the tracheal tube is connected to other pipelines can be buffered and absorbed, preventing the pipeline connection operation from affecting the supporting effect of the first support rod and the second support rod on the patient's mouth, while improving the safety of the patient.

[0019] By setting up a C-shaped bend plate, not only can the laryngoscope be assisted in guiding, but the operator can also use the C-shaped bend plate as a fulcrum to change the angle at which the laryngoscope opens the patient's mouth, thereby reducing the force required on the operator's hands, reducing the difficulty of operation, and improving surgical efficiency.

[0029] like Figures 1 to 5As shown in the figure, an embodiment of the present invention provides an intubation anesthesia assistance device, which includes a bottom plate 1. A limiting plate 102 is fixedly connected to the top of the bottom plate 1. An airbag 2 is inserted into the limiting plate 102. A neck positioning plate 3 and a shoulder positioning plate 101 are symmetrically installed on the top of the bottom plate 1. One end of the airbag 2 close to the neck positioning plate is fixedly connected with a neck pad 201. An air inlet and an air outlet are respectively arranged on both sides of the airbag 2. The neck pad 201 has an upwardly convex arc-shaped profile. The airbag 2 and the neck pad 201 are integrally manufactured structures that are interconnected. The shoulder positioning plate 101 has an arc-shaped profile. A first bending portion 301 is installed at the middle position of the neck positioning plate 3, and a second bending portion 302 is installed at the top of the neck positioning plate 3. The first bending portion 301 has an inwardly concave profile, and the second bending portion 302 has an outwardly convex profile; a positioning component, which is used to assist the operator in arranging the tracheal intubation 12 and the laryngoscope 11, and the positioning component is connected to the neck positioning plate 3.

[0030] The intubation anesthesia assistance device provided in this application is mainly applicable to patients under general anesthesia, and uses the tracheal intubation 12 to maintain the respiratory function of the patient. Compared with the prior art, the assistance device provided in this application can effectively improve the convenience of the operator during the tracheal intubation 12 operation on the patient, reduce the burden on the operator's hand operation, improve the efficiency of the tracheal intubation 12 operation, and provide a safer and more comfortable surgical environment for the patient.

[0031] Specifically, by installing an airbag 2, a shoulder positioning plate 101, and a neck positioning plate 3 on the bottom plate 1, the position of the patient can be limited. During the actual operation, the bottom plate 1 is placed on the operating bed, and the upper body of the patient is pressed on the top of the bottom plate 1. The bottom plate 1 is fixed by the pressure of the patient's own body. When the patient lies flat, the tops of the patient's shoulders abut against the inner wall of the shoulder positioning plate 101. Since the shoulder positioning plate 101 has an arc-shaped contour, such a structural setting can improve the adaptability of the shoulder positioning plate 101 to the contour of the patient's shoulders, thereby improving the positioning effect of the shoulder positioning plate 101 on the patient's shoulders and the comfort of the patient's shoulders; when the patient lies flat, the patient's neck is located at the middle position between the two neck positioning plates 3. The back of the patient's neck fits against the top of the neck pad 201, and the patient's head fits against the top of the airbag 2. The airbag 2 is arranged within the limiting plate 102, and the height of the limiting plate 102 is greater than the height of the airbag 2. Therefore, the airbag 2 can be limited to prevent the airbag 2 from shifting in position after inflation. Since the first bending portion 301 and the second bending portion 302 are provided on the neck positioning plate 3, and the first bending portion 301 has an inwardly concave contour, and the second bending portion 302 has an outwardly convex contour, such a radian setting is to improve the adaptability of the neck positioning plate 3 to the contour of the patient's neck. Among them, the inwardly concave contour of the first bending portion 301 is provided to enable the neck positioning plate 3 to wrap and position the patient's neck, and the outwardly convex contour of the second bending portion 302 is to facilitate the patient to lie down on the middle of the neck positioning plate 3 from top to bottom. The outwardly convex contour of the second bending portion 302 can be used to assist in guiding the patient's neck, which not only improves the efficiency of placing the patient's position, but also prevents the patient's neck from being scratched by the neck positioning plate 3; after the patient lies down, the operator fills the airbag 2 with air. After the airbag 2 bulges, the neck pad 201 will also expand accordingly. Since the neck pad 201 has an upwardly convex arc-shaped contour, when the neck pad 201 is inflated, the patient's neck can be raised. Such a setting makes the patient's mouth, pharynx, and larynx in a straight line after the patient's neck is raised, thus making it more convenient for the operator to insert the tracheal intubation 12 into the patient's trachea.

[0032] Through the setting of the above structure, after the patient lies on the hospital bed, the position of the patient can be positioned by means of the shoulder positioning plate 101 and the neck positioning plate 3. Such a setting improves the stability of the patient's body. When the airbag 2 is inflated and expanded, the neck pad 201 will raise the patient's neck. At this time, under the positioning effect of the shoulder positioning plate 101 and the neck positioning plate 3, the patient's mouth, pharynx, and larynx are in a straight line, thus making it more convenient for the operator to insert the tracheal intubation 12 into the patient's body, improving the success rate and convenience of the tracheal intubation 12 operation, and reducing the damage to the patient's throat during the intubation process.

[0033] The auxiliary device provided by this application is also provided with a positioning component. The positioning component can assist the operator in holding and fixing the laryngoscope 11 and the tracheal intubation 12, so that the operator does not need to hold the laryngoscope 11 and the tracheal intubation 12 with hands all the time, improving the convenience of the operator when performing other operations. In addition, the positioning component can assist the operator in opening the patient's mouth, and the size of the opened patient's mouth can be quickly adjusted. This not only improves the operator's surgical field of view, but also increases the success rate during the insertion process of the tracheal intubation 12. At present, after the tracheal intubation 12 is inserted, a bite block is needed to protect the tracheal intubation 12. In this application, the setting of the positioning component not only eliminates the bite block, but also can automatically achieve the fixing effect of the tracheal intubation 12, thereby further reducing the difficulty of surgical operations and improving the efficiency of the operator.

[0034] As an implementation manner in this embodiment, as Figures 1 to 5 shown, the positioning component includes a first pull rod 4 and a second pull rod 5 inserted into the neck positioning plate 3. One end of the first pull rod 4 and the second pull rod 5 close to the neck positioning plate 3 are both fixedly connected with an S-shaped bent rod 6. The contour of the S-shaped bent rod 6 is in an "S" shape. A weakening groove 601 is formed on the S-shaped bent rod 6, and the weakening groove 601 thins the S-shaped bent rod 6. The second bending part 302 is successively provided with a straight chute 303 and a limiting groove 304 from top to bottom. A plurality of protrusions are arranged at the top of the limiting groove 304. The first pull rod 4 and the second pull rod 5 are respectively arranged on the neck positioning plates 3 on both sides of the patient's neck. The connection manner between the first pull rod 4 and the second pull rod 5 and the neck positioning plate 3 is the same. Here, the first pull rod 4 is taken as an example for explanation. One end of the first pull rod 4 close to the neck positioning plate 3 is provided with an S-shaped bent rod 6. The S-shaped bent rod 6 not only has an "S" shape in contour, but also the S-shaped bent rod 6 is respectively inserted into the straight chute 303 and the limiting groove 304 on the neck positioning plate 3 from top to bottom (as Figure 2 and Figure 4As shown in the figure, the staggered structure enables the S-shaped bent rod 6 to be limited by the straight chute 303 and the limiting groove 304, preventing dislocation and detachment of the S-shaped bent rod 6 during the sliding process on the neck positioning plate 3. Since the weakening groove 601 is provided on the S-shaped bent rod 6 and the S-shaped bent rod 6 is thinned at the weakening groove 601, the S-shaped bent rod 6 is prone to deformation at the position of the weakening groove 601 under the action of an external force. The limiting groove 304 consists of two parts. The top is provided with a plurality of protrusions, and the distance between each protrusion matches the size of the S-shaped bent rod 6. The bottom of the limiting groove 304 is a flat groove body. In the initial state, the end of the S-shaped bent rod 6 is clamped at the top of the limiting groove 304 and is blocked and limited by the protrusions at the top of the limiting groove 304. When the operator needs to slide the S-shaped bent rod 6, first press down the end of the S-shaped bent rod 6 to deform the S-shaped bent rod 6 at the position of the weakening groove 601, and move the end of the S-shaped bent rod 6 from the top of the limiting groove 304 to the bottom of the limiting groove 304. At this time, the protrusions at the top of the limiting groove 304 can no longer block the S-shaped bent rod 6, and the operator can slide and adjust the position of the S-shaped bent rod 6. When it is necessary to fix the S-shaped bent rod 6 again, stop pressing the S-shaped bent rod 6. After losing the pressure, the S-shaped bent rod 6 will reset to the top of the limiting groove 304 under its own elastic force and be re-limited and fixed by the protrusions at the top of the limiting groove 304. Through the setting of the above structure, under the combined action of the structures of the S-shaped bent rod 6, the straight chute 303 and the limiting groove 304, the first pull rod 4 and the second pull rod 5 are assembled with the neck positioning plate 3, and both the first pull rod 4 and the second pull rod 5 can slide on the neck positioning plate 3, with good stability and convenient operation during the sliding process.

[0035] In this embodiment, as Figures 1 to 9As shown, one end of the first pull rod 4 is clamped with the first support rod 401, and one end of the second pull rod 5 is clamped with the second support rod 501. The other ends of the first pull rod 4 and the second pull rod 5 are fixedly connected with a clamp 9. A clamping groove 10 is provided at the middle position of the first support rod 401 and the second support rod 501. The first pull rod 4 and the first support rod 401 and the second pull rod 5 and the second support rod 501 are fixed by the clamp 9. The size of the clamp 9 is consistent with the size of the clamping groove 10. The first pull rod 4 and the second pull rod 5 are both installed with a clamp 9. The clamp 9 is used to connect and fix the first support rod 401 and the second support rod 501. Since the size of the clamp 9 is consistent with the size of the clamping groove 10, and the clamp 9 has a "C"-shaped profile, the operator The operator can use the "C"-shaped profile of the chuck 9 to press and clamp the first support rod 401 and the second support rod 501 in the chuck 9. When the first support rod 401 and the second support rod 501 are clamped and fixed together with the chuck 9, the first support rod 401 and the second support rod 501 cannot move or rotate due to the action of friction and clamping force. When the operator pries the first support rod 401 and the second support rod 501 with force, the two can rotate on the chuck 9. This installation method not only allows the first support rod 401 and the second support rod 501 to be removed from the first pull rod 4 and the second pull rod 5, but also allows the relative angles between the first support rod 401 and the second support rod 501 and the first pull rod 4 and the second pull rod 5 to be changed by hand.

[0036] In this embodiment, if Figures 1 to 12As shown, the first support rod 401 is fixedly connected to the first curved plate 402, and the second support rod 501 is fixedly connected to the second curved plate 502. The first support rod 401 and the first curved plate 402 and the second support rod 501 and the second curved plate 502 are fixed by elastic bent rods 7. The first support rod 401 and the second support rod 501 both have a "C"-shaped profile, and both ends of the first support rod 401 and the second support rod 501 are fixedly connected to an inwardly bent bent rod, and both ends of the first curved plate 402 are fixedly connected to the insertion portion 403, and the second curved plate 402 is fixedly connected to the insertion portion 403. Both ends of the shaped plate 502 are fixedly connected with an outward-turned portion 503, and the outward-turned portion 503 has an outward-turned edge profile. A slot 504 that matches the size of the insertion portion 403 is opened on the outward-turned portion 503. The first support rod 401 and the second support rod 501 are fixedly connected with a C-shaped bent plate 8. The C-shaped bent plate 8 has a "C"-shaped profile, and the elastic bent rod 7 is a curved elastic structure. During actual operation, the operator needs to use the first support rod 401 and the second support rod 501 to prop up and open the patient's mouth. Specifically, the operator allows the first support rod 401 to contact the patient's lower teeth. The first support rod 401 and the second support rod 501 are placed on the inner wall of the patient's upper teeth, and then the positions of the first pull rod 4 and the second pull rod 5 on the neck positioning plate 3 are manually adjusted to increase the distance between the first pull rod 4 and the second pull rod 5, thereby achieving the effect of opening the patient's mouth. Since the first support rod 401 and the second support rod 501 are both "C"-shaped profiles, when the first support rod 401 and the second support rod 501 are placed on the inner wall of the patient's teeth, the "C"-shaped profile structure allows the two ends of the first support rod 401 and the second support rod 501 to extend from the inner wall of the patient's teeth. It extends to the vicinity of the gum position, thereby making the contact area between the first support rod 401 and the second support rod 501 and the patient's teeth larger, improving the firmness and stability of the fit between the first support rod 401 and the second support rod 501 and the patient's teeth, and preventing slippage during the support process. Since both ends of the first support rod 401 and the second support rod 501 are fixedly connected with an inwardly bent bent rod, the inwardly bent bent rod makes the end structure of the first support rod 401 and the second support rod 501 more rounded, thereby preventing the first support rod 401 and the second support rod 501 from scratching the patient's mouth.

[0037] Furthermore, the operator can use the first support rod 401 and the second support rod 501 to open the patient's oral cavity. At the same time, with the cooperation of the S-shaped bent rod 6 and the neck positioning plate 3, the operator can adjust the distance between the first support rod 401 and the second support rod 501, thereby changing the size of the patient's oral cavity being opened. This way of opening not only does not affect the tissues inside the patient's oral cavity, but also does not block any view inside the patient's oral cavity, thus ensuring the efficiency of the operator during the tracheal intubation 12 operation on the patient. At the same time, since the first support rod 401 and the second support rod 501 have a detachable and assembled structure, during actual use, the operator can choose the sizes of the first support and the second support rod 501 according to the patient's own situation to adapt to more patients. In addition, the angles of the first support rod 401 and the second support rod 501 can be adjusted by manually bending, so as to better fit the contour of the patient's oral cavity, improving the patient's comfort and the effect of supporting and opening the patient's oral cavity at the same time.

[0038] The first arc plate 402 and the second arc plate 502 are respectively installed on the first support rod 401 and the second support rod 501. The first arc plate 402 and the second arc plate 502 can be snap-fitted and fixed together. Since their sizes are in line with those of the tracheal intubation 12 after being snap-fitted, the tracheal intubation 12 can be fixed when they are snap-fitted. Specifically, the operator can shorten the distance between the first arc plate 402 and the second arc plate 502 and insert the insertion part 403 into the slot 504. Since the sizes of the insertion part 403 and the slot 504 are in line with each other, they can be mutually limited after being plugged together. In addition, an outward-turning part 503 is provided on the second arc plate 502. Since the outward-turning part 503 has a contour of turning outwards, during the process of inserting the insertion part 403 into the slot 504, the contour of the outward-turning part 503 turning outwards can be used for auxiliary guiding, so as to ensure that the insertion part 403 will not deviate or be misaligned, improving the convenience of the surgical operation. After the operator inserts the tracheal intubation 12 into the patient's body, the tracheal intubation 12 can be fixed by means of the first arc plate 402 and the second arc plate 502, so that the operator does not need to manually hold the tracheal intubation 12. Moreover, the first support rod 401 and the second support rod 501 can open and support the patient's oral cavity. Therefore, when holding and fixing the tracheal intubation 12, it will not cause the patient's teeth to bite the tracheal intubation 12, thus eliminating the dental pad used at the present stage and saving medical costs.

[0039] Furthermore, since the first support rod 401 and the first arc-shaped plate 402, as well as the second support rod 501 and the second arc-shaped plate 502, are fixed by the elastic bent rod 7, and the elastic bent rod 7 is a curved surface elastic structure, such a setting enables the first support rod 401 and the first arc-shaped plate 402, as well as the second support rod 501 and the second arc-shaped plate 502, to generate a certain amount of elastic deformation by means of the elastic bent rod 7. After the tracheal intubation 12 is fixed, the operator needs to connect other pipelines to the tracheal intubation 12. When connecting other pipelines, it is inevitable to cause shaking and pulling on the tracheal intubation 12, which will not only affect the stability of the first support rod 401 and the second support rod 501 to support and open the patient's oral cavity, but also cause certain frictional damage to the patient's trachea. By setting the elastic bent rod 7, the shaking and pulling on the tracheal intubation 12 can be buffered and absorbed, preventing the effect of the first support rod 401 and the second support rod 501 to support the patient's oral cavity from being affected by the pipeline connection operation, and improving the safety of the patient at the same time.

[0040] Still further, C-shaped bent plates 8 are installed on both the first support rod 401 and the second support rod 501. Since the size of the C-shaped bent plate 8 is compatible with that of the laryngoscope 11, the operator can use the C-shaped bent plate 8 to assist in positioning the laryngoscope 11. During the actual operation, the operator needs to rotate the angle of the laryngoscope 11 to open the patient's glottis. When the operator holds the laryngoscope 11, the laryngoscope 11 should not touch the patient's teeth to avoid grinding the patient's teeth. In this application, since the C-shaped bent plate 8 is arranged on the first support rod 401 and the second support rod 501, such a position setting can not only assist in guiding the laryngoscope 11, but also enable the operator to change the opening angle of the laryngoscope 11 on the patient's oral cavity with the C-shaped bent plate 8 as the fulcrum, thereby reducing the force required by the operator's hand, reducing the operation difficulty, and improving the operation efficiency.

[0041] The working principle of the technical solution provided by the present invention is as follows: When in use, first let the anesthetized patient lie on the bottom plate 1, and let the tops of the patient's shoulders abut against the inner wall of the shoulder positioning plate 101. Since the shoulder positioning plate 101 has a circular arc profile, such a structural setting can improve the adaptability of the shoulder positioning plate 101 to the patient's shoulder profile, thereby improving the positioning effect of the shoulder positioning plate 101 on the patient's shoulders and the comfort of the patient's shoulders. The patient's neck is located at the middle position between the two neck positioning plates 3. The back of the patient's neck is attached to the top of the neck pad 201, and the patient's head is attached to the top of the airbag 2. Since the first bending portion 301 and the second bending portion 302 are provided on the neck positioning plate 3, and the first bending portion 301 has an inwardly concave profile, and the second bending portion 302 has an outwardly convex profile, such a radian setting is to improve the adaptability of the neck positioning plate 3 to the patient's neck profile. Among them, the inwardly concave profile of the first bending portion 301 is provided to allow the neck positioning plate 3 to wrap and position the patient's neck. The outwardly convex profile of the second bending portion 302 is to facilitate the patient to lie down on the neck positioning plate 3 from top to bottom. When the patient lies down, the outwardly convex profile of the second bending portion 302 can be used to assist in guiding the patient's neck, which can not only improve the efficiency of patient position placement, but also prevent the patient's neck from being scratched by the neck positioning plate 3.

[0042] After the patient lies in place, the operator fills the airbag 2 with air. After the airbag 2 bulges, the neck pad 201 will also expand accordingly. Since the neck pad 201 has an upwardly convex circular arc profile, when the neck pad 201 is inflated, it can lift the patient's neck. Such a setting makes the patient's mouth, pharynx, and larynx in a straight line after the patient's neck is lifted, which is more convenient for the operator to insert the tracheal intubation 12 into the patient's trachea.

[0043] The operator manually adjusts the relative positions of the first pull rod 4 and the second pull rod 5 on the neck positioning plate 3, so that the top of the first pull rod 4 is located at the position of the patient's lower teeth, and the top of the second pull rod 5 is located at the position of the patient's upper teeth. First, press down the end of the S-shaped bent rod 6, so that the S-shaped bent rod 6 deforms from the position of the weakening groove 601, and the end of the S-shaped bent rod 6 moves from the top of the limiting groove 304 to the bottom of the limiting groove 304. At this time, the protrusion at the top of the limiting groove 304 can no longer block the S-shaped bent rod 6, and the operator can slide and adjust the position of the S-shaped bent rod 6. When it is necessary to fix the S-shaped bent rod 6 again, stop pressing the S-shaped bent rod 6. After losing the pressure, the S-shaped bent rod 6 will reset to the top of the limiting groove 304 under the action of its own elastic force and be limited and fixed again by the protrusion at the top of the limiting groove 304. After the positions of the first pull rod 4 and the second pull rod 5 are adjusted, the operator makes the first support rod 401 contact the inner wall of the patient's lower teeth, and makes the second support rod 501 contact the inner wall of the patient's upper teeth. Then, manually adjust the positions of the first pull rod 4 and the second pull rod 5 on the neck positioning plate 3 to increase the distance between the first pull rod 4 and the second pull rod 5, so as to achieve the effect of opening the patient's oral cavity. Since both the first support rod 401 and the second support rod 501 have a "C"-shaped contour, when the first support rod 401 and the second support rod 501 are placed on the inner wall of the patient's teeth, the "C"-shaped contour structure enables the two ends of the first support rod 401 and the second support rod 501 to extend from the inner wall of the patient's teeth to the vicinity of the gum position, so that the contact area between the first support rod 401 and the second support rod 501 and the patient's teeth is larger, improving the firmness and stability of the cooperation between the first support rod 401 and the second support rod 501 and the patient's teeth, and preventing the phenomenon of slipping during the support process. Since both ends of the first support rod 401 and the second support rod 501 are fixedly connected with bent rods bent inward, the bent rods bent inward make the end structures of the first support rod 401 and the second support rod 501 more rounded, thus preventing the first support rod 401 and the second support rod 501 from scratching the patient's oral cavity.

[0044] After the patient's oral cavity is propped open, the operator uses the laryngoscope 11 to open the patient's glottis. Since the size of the C-shaped curved plate 8 matches that of the laryngoscope 11, the operator can use the C-shaped curved plate 8 to assist in positioning the laryngoscope 11. During the actual operation, the operator uses the C-shaped curved plate 8 as a fulcrum to change the opening angle of the laryngoscope 11 on the patient's oral cavity, thereby reducing the force required by the operator's hand, lowering the operation difficulty, and improving the surgical efficiency. After the patient's glottis is opened, the tracheal intubation 12 is inserted into the patient's body. After the tracheal intubation 12 is inserted, the laryngoscope 11 is removed. Then, the operator shortens the distance between the first arc-shaped plate 402 and the second arc-shaped plate 502, and inserts the insertion part 403 into the slot 504. Since the sizes of the insertion part 403 and the slot 504 match, they can limit each other after being inserted together. Since the sizes of the first arc-shaped plate 402 and the second arc-shaped plate 502 match those of the tracheal intubation 12 after being clamped together, the tracheal intubation 12 can be fixed by using the first arc-shaped plate 402 and the second arc-shaped plate 502, so that the operator does not need to manually hold the tracheal intubation 12. Moreover, the first support rod 401 and the second support rod 501 can prop open the patient's oral cavity. Therefore, when holding and fixing the tracheal intubation 12, the patient's teeth will not bite the tracheal intubation 12, thus eliminating the dental pad used at the present stage and saving the medical cost.
