Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a bite block for tracheal intubation. Background Art

[0002] Tracheal intubation is a core first-aid technique for saving lives in modern medicine. By inserting a special catheter through the mouth or nose into the trachea to establish an artificial airway to maintain respiratory function. Taking oral tracheal intubation as an example, in order to prevent the patient from biting and flattening the catheter during anesthesia or unconsciousness, resulting in an asphyxiation risk, a bite block is used to be placed in the patient's mouth to prevent the patient from biting and flattening the tracheal intubation. However, the currently used bite blocks do not have an adjustment function. For example, a rotary split bite block with the publication number CN118217495A can only rotate the bite block after it is placed in the oral cavity to replace the left and right positions of the tracheal intubation to improve the patient's oral condition during use, but it cannot adjust the opening amplitude of the patient's oral cavity by adjusting the bite block after the patient bites the bite block. After the patient's mouth maintains a fixed opening amplitude for a long time, discomfort will occur. At the same time, in this patent, during use, medical tape in a butterfly shape is also needed to wind the bite block and the tracheal intubation together to maintain the position stability of the tracheal intubation. However, every time the patient's oral cavity is cleaned, the medical tape needs to be removed. After the oral cavity is cleaned, the medical tape needs to be wound around the bite block and the tracheal intubation again. Such repeated operations will bring a lot of inconvenience to the nursing work of medical staff. Summary of the Invention

[0014] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0015] Firstly, this patent application can achieve expansion adjustment of the two top plates by means of the top plates arranged in the grooves on both sides of the tooth pad body, and the coordinated movement of the adjustment tube, the clamping ring, the guide groove and the guide rod, so as to adjust the support range from inside the patient's mouth, which can solve the problems encountered in actual medical care. Moreover, during operation, a series of operational adjustments of the top plate lifting and lowering can be achieved by repeatedly rotating the adjustment tube. Not only is the operation simple, but the tendon tissue around the patient's jaw can also be mobilized anytime and anywhere to relieve the discomfort caused by being in a fixed posture for a long time.

[0016] Secondly, by rotating the adjusting member, the adjusting tube can be driven to a certain angle, so that the two top plates can be expanded from the groove of the tooth pad main body to the outside, thereby adjusting the opening range of the patient's mouth. At the same time, in order to realize the hovering function after the top plate is expanded, a sleeve, a baffle and a spring are arranged in the hole area of ​​the tooth pad main body. When the baffle is subjected to the thrust of the spring and causes multiple latch teeth and multiple latch teeth on the adjusting member to engage with each other, the baffle will restrict the rotatable state of the adjusting member, so that the adjusting member cannot rotate in a natural state, thereby forming a locking function for the state of the adjusting tube and the two clamping rings after the rotation adjustment is completed, thereby preventing the two top plates from retracting into the groove of the tooth pad main body when subjected to the pressure of the patient's teeth occlusion; when the adjusting tube needs to be rotated, the baffle only needs to be pushed toward the direction of the tooth pad main body, so that the multiple latch teeth on the baffle and the multiple latch teeth on the adjusting member can be separated, thereby releasing the rotation restriction on the adjusting member.

[0017] Thirdly, in this patent application, the dental pad body and the bottom plate are designed to be detachable, so that the bottom plate can be removed without removing the dental pad body, which can avoid blocking the patient's mouth and enable medical staff to normally use cleaning tools to clean the patient's oral cavity, so as to keep the dental pad between the patient's teeth during the cleaning process and prevent losing the protection of the tracheal intubation. It can prevent the patient from biting flat the tracheal intubation or causing occlusal damage to the tracheal intubation due to removing the dental pad body, further improving the service life after tracheal intubation placement and reducing the risk of air leakage caused by tracheal intubation damage.

[0018] Fourthly, when disassembling the dental pad, the bottom plate and the tracheal intubation, it is not necessary to repeatedly disassemble and assemble the medical adhesive tape. It saves time and effort in operation. Using medical adhesive tape not only easily causes the sticky part to contaminate the patient's mouth and the medical staff's hands, but also in medical operations, medical tape is a disposable item and needs to be replaced in time after disassembly to ensure normal use and avoid contamination. Therefore, there will be a certain amount of waste of medical resources. However, this patent application does not require the use of medical tape, which can effectively save medical resources and is more in line with modern medical use. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0041] The following will, with reference to the drawings, elaborate on the technical solutions provided by each embodiment of the present invention.

[0042] An embodiment of the present invention provides a bite block for tracheal intubation, including a bottom plate 1; the overall shape of the bottom plate 1 is an elliptical structure, and a through groove 11 is provided in the middle of the bottom plate 1; a bite block support 2 that can support between the upper teeth and the lower teeth of the patient is inserted at the through groove 11; a clamping groove 12 for placing the tracheal intubation is provided on one side of the bottom plate 1; an intubation fixator 3 that can fix the placed tracheal intubation is provided at the clamping groove 12 of the bottom plate 1, and the clamping groove 12 on the bottom plate 1 extends to the outer area of the bottom plate 1, so that two protruding parts 13 are formed on one side part of the bottom plate 1 provided with the clamping groove 12.

[0043] When this application is in use, the bite block support 2 can be placed into the patient's mouth and between the upper teeth and the lower teeth for biting to prevent the tracheal intubation from being bitten flat, while the bottom plate 1 is placed outside the patient's oral cavity. The bottom plate 1 can form a block from outside the mouth during use to prevent the entire bite block support 2 from falling into the patient's airway. Among them, the bottom plate 1 is elliptical, and the outer edge part of the bottom plate 1 is more fitted to the outer contour of the oral cavity during use, which can reduce the compression on the lips and cheeks, disperse the supporting force, and reduce the discomfort of the patient wearing it for a long time. At the same time, it is not necessary to use medical adhesive tape to tie the bite block and the tracheal intubation together to prevent the bite block from falling into the patient's mouth and blocking the airway as in the prior art; secondly, the clamping groove 12 on the bottom plate 1 can be used for placing the tracheal intubation, and thus it is not necessary to use medical adhesive tape to tie and connect with the bite block. During the actual operation process, since the tracheal intubation is placed into the patient's airway, in order to ensure smooth ventilation of the patient, the tracheal intubation cannot be pulled randomly. Therefore, in order to facilitate the placement of the tracheal intubation into the clamping groove 12 on the bottom plate 1, the setting method of extending the clamping groove 12 on the bottom plate 1 to its own outer area can enable the tracheal intubation to gradually transfer from the protruding part 13 on the bottom plate 1 to the clamping groove 12 area, and can complete the placement work of the tracheal intubation and the bite block support 2 without pulling out the bite block support 2.

[0044] In a further preferred embodiment, referring to the attached Figure 3 As shown, the bite block support 2 includes a bite block main body 21; the bite block main body 21 is a cuboid structure, and a through hole 22 penetrating through the front and rear ends is provided inside the bite block main body 21; an extension part 23 is extended and provided at the lower half part near the rear end of the bite block main body 21.

[0045] The through hole 22 in the tooth pad body 21 can provide a circulation channel for the exhalation in the patient's airway and the gas exchange in the cavity, so that the patient's cavity can maintain normal air contact; and the through hole 22 set inside the tooth pad body 21 can also be used by medical staff to extend the suction tube into the through hole 22 when bleeding or excessive sputum occurs in the patient's mouth, and then use the suction device to suck out the blood and sputum in the patient's mouth, thereby helping to improve the cleanliness and comfort of the patient's mouth. At the same time, it can also reduce the risk of the patient choking on the trachea due to excessive sputum during the operation, thereby achieving the dual-channel function of ventilation and cleaning through the through hole 22 set on the tooth pad body 21, reducing the risk of sputum blocking the airway; during use, it can achieve the effects of cavity opening and closing support, endotracheal tube fixation, and convenient sputum suction and cavity cleaning.

[0046] Secondly, the extension portion 23 disposed at the rear end of the bite block body 21 can abut against the patient's tongue during use, so that the tongue will not retract to a large extent in a natural state and affect the normal use of the endotracheal tube.

[0047] In a further preferred embodiment, refer to the attached Figures 4 to 7 As shown, grooves 24 are provided on both upper and lower sides of the tooth pad body 21 near the extension portion 23, and the grooves 24 are connected to the through holes 22 inside the tooth pad body 21; a top plate 25 matching the size of the groove 24 is provided in each groove 24, and the top plate 25 can move outward within the groove 24 area on the tooth pad body 21; an adjustment tube 4 is inserted into the through hole 22 of the tooth pad body 21, and the adjustment tube 4 can rotate in the through hole 22 of the tooth pad body 21, and the adjustment tube 4 is provided with through holes 22 running through both ends of itself; the tooth pad body 21 Arc-shaped grooves 26 are provided in the through hole 22 of the body 21 and at both ends of the corresponding groove 24 and at both ends of each top plate 25. The arc-shaped grooves 26 at both ends of the corresponding groove 24 in the tooth pad body 21 are just annular after being spliced ​​with the arc-shaped grooves 26 at both ends of the top plate 25; two snap rings 41 are sleeved on the adjustment tube 4, and the two snap rings 41 are fixedly connected to the adjustment tube 4. The two snap rings 41 are respectively arranged inside the tooth pad body 21 and in the annular area formed by splicing the arc-shaped grooves 26 at both ends of the upper and lower top plates 25, and the snap rings 41 can rotate in the arc-shaped grooves 26.

[0048] In a further preferred embodiment, two symmetrical guiding grooves 42 are provided on each of the two snap rings 41. The guiding grooves 42 are in an arc-shaped trajectory, and the inner arc edge of the arc-shaped trajectory is arranged towards the direction of the through hole 22. The guiding grooves 42 are arranged obliquely on the snap rings 41, that is, one end of the guiding groove 42 towards the clockwise rotation direction of the snap ring 41 is close to the edge part of the snap ring 41, and the other end of the guiding groove 42 is close to the through hole 22 part; a guide rod 27 is arranged in the arc-shaped clamping groove 26 of the top plate 25. The guide rod 27 is inserted into the guiding groove 42 on the snap ring 41, and one end of the guide rod 27 is fixedly connected to the inner wall of the arc-shaped clamping groove 26 of the top plate 25, that is, the guide rods 27 in the arc-shaped clamping grooves 26 at both ends of each top plate 25 are respectively arranged in the guiding grooves 42 in the same direction of the two snap rings 41. By rotating the snap ring 41, the guide rod 27 can be driven to drive the top plate 25 to move up and down;

[0049] Refer to the attached Figure 8 and 9 As shown, when the dental pad supporter 2 is placed into the patient's mouth, the two top plates 25 on the upper and lower sides of the dental pad main body 21 need to be respectively placed within the pressing range of the patient's upper teeth and lower teeth, so that the patient's teeth come into contact with the two top plates 25. After the dental pad supporter 2 is placed in the patient's mouth for a period of time, if it is necessary to adjust the opening amplitude of the patient's oral cavity, the two snap rings 41 can be driven to rotate synchronously by rotating the adjusting tube 4. Taking the rotation of the adjusting tube 4 in the counterclockwise direction as an example, the guiding grooves 42 on the two snap rings 41 will move in the arc-shaped clamping grooves 26 of the upper and lower two top plates 25. Since one end of the guiding groove 42 towards the clockwise rotation direction of the snap ring 41 is close to the edge part of the snap ring 41, and the other end of the guiding groove 42 is close to the through hole 22 part, therefore, when the guiding groove 42 rotates with the snap ring 41, the guide rod 27 will move in the corresponding guiding groove 42 and be subjected to the thrust applied by the inner wall part of the guiding groove 42 towards the outer side of the groove 24 of the dental pad main body 21. As the snap ring 41 rotates, the guide rod 27 will gradually move towards the part of the guiding groove 42 close to the edge of the snap ring 41 along the inclination direction of the guiding groove 42, so that the entire top plate 25 extends from the groove 24 of the dental pad main body 21 to the outer area, thereby increasing the thickness on the upper and lower sides of the dental pad main body 21 and gradually expanding the opening amplitude of the patient's oral cavity originally the same as the thickness of the dental pad main body 21;

[0050] When it is necessary to retract the two top plates 25 to the groove 24 area on the tooth pad body 21, it is only necessary to rotate the adjustment tube 4 in the opposite direction to drive the corresponding two clamping rings 41 and the guide groove 42 to rotate, so that the guide rod 27 inserted in the guide groove 42 gradually approaches the through hole 22 from the edge portion originally close to the clamping ring 41, thereby driving the corresponding top plate 25 to slowly retract into the groove 24 of the tooth pad body 21, and until the two top plates 25 are completely retracted into the groove 24, so that the patient's oral opening range is returned to the same thickness as the tooth pad body 21; in actual use, the adjustment tube 4 can be repeatedly rotated several times to achieve the lifting and lowering adjustment of the two top plates 25 in the groove 24 of the tooth pad body 21, so as to activate the jaw joint and the surrounding muscle tissue through the protrusion and retraction adjustment of the two top plates 25, so that the patient's oral cavity can be relaxed to a certain extent after being in a fixed opening range for a period of time, so as to reduce the soreness and discomfort of the patient's mouth after maintaining a fixed opening range for a long time;

[0051] Compared with the traditional bite block currently used in hospitals, when the bite block is tied to the endotracheal tube, if the patient's oral opening range needs to be adjusted to achieve the purpose of auxiliary movement, the patient's upper and lower teeth or the entire chin can only be moved manually to achieve the movement of the jaw. However, in actual operation, the tendon tissue around the jaw of some comatose patients will become stiff due to being in a fixed posture for a long time, and it is difficult for medical staff to insert their fingers between the patient's teeth to form traction control. At the same time, there are some patients with facial wounds. Medical staff also have the risk of contacting the facial wound and causing infection when performing jaw movement from the outside of the patient's mouth. Moreover, if instruments are used to reach into the patient's mouth to adjust the opening range between the teeth, once the operation is wrong, the instruments may scratch the patient's oral mucosa or irritate the cavity mucosa, which will cause greater harm to the patient. It is especially suitable for patients with blurred consciousness or agitation, which is even more difficult to achieve in actual operation.

[0052] Therefore, it is difficult for medical staff to successfully complete multiple activities on the patient's cavity. The present patent application can achieve expansion adjustment of the two top plates 25 by setting the top plates 25 in the grooves 24 on both sides of the tooth pad body 21, and the coordinated movement of the adjustment tube 4, the clamping ring 41, the guide groove 42 and the guide rod 27, so as to achieve adjustment of the support range from the patient's mouth, which can solve the problems encountered in actual medical care. Moreover, during operation, a series of operational adjustments of the lifting and lowering of the top plate 25 can be achieved by repeatedly rotating the adjustment tube 4. Not only is the operation simple, but the tendon tissue around the patient's jaw can be moved anytime and anywhere to relieve the discomfort caused by being in a fixed posture for a long time.

[0053] In a further preferred embodiment, refer to the attached Figures 4 to 7As shown, one end of the adjustment tube 4 away from the extension part 23 passes through the through hole 22 of the mouthguard body 21 and extends a certain distance outside the mouthguard body 21. An adjusting member 43 is provided at the extending end of the adjustment tube 4 outside the mouthguard body 21. The adjusting member 43 is in a circular ring structure. The circular ring-shaped adjusting member 43 is sleeved on the adjustment tube 4 and is fixedly connected to the adjustment tube 4;

[0054] The adjusting member 43 can be held and operated by medical staff to control the adjustment tube 4. By rotating the adjusting member 43, the entire adjustment tube 4 can be driven to rotate within the mouthguard body 21 to adjust the top block.

[0055] In a further preferred embodiment, referring to FIGS. Figure 5 、 6 、11 and 12, a placement hole 28 is provided at one end of the mouthguard body 21 away from the extension part 23 and inside the through hole 22; a sleeve 44 with a circular ring structure is provided inside the placement hole 28. The sleeve 44 is sleeved on the adjustment tube 4 and is located inside the placement hole 28. The sleeve 44 can slide on the adjustment tube 4; a spring 45 is provided inside the placement hole 28. The spring 45 is located between the sleeve 44 and the inner wall of the placement hole 28 of the mouthguard body 21. Under the pushing force of the spring 45, a pushing force towards the adjusting member 43 can be always exerted on the sleeve 44; a clamping block 46 is fixedly provided on the outer side wall of the sleeve 44; a sliding groove 29 corresponding to the position of the clamping block 46 is provided on the inner wall of the mouthguard body 21 at the placement hole 28. The length of the sliding groove 29 is the same as the slidable distance of the sleeve 44 and the clamping block 46 on the adjustment tube 4; a circular ring-shaped baffle 47 is fixedly provided on one side of the sleeve 44 facing the adjusting member 43, that is, the circular ring-shaped baffle 47 is sleeved on the adjustment tube 4 and can slide on the adjustment tube 4 following the sleeve 44; a plurality of engaging teeth 48 are provided on one side of the baffle 47 facing the adjusting member 43. A plurality of engaging teeth 48 that can be engaged with the plurality of engaging teeth 48 on the baffle 47 are provided on one side of the adjusting member 43 facing the baffle 47. When the plurality of engaging teeth 48 on the baffle 47 are engaged with the plurality of engaging teeth 48 on the adjusting member 43, the baffle 47 can control the adjusting member 43 from rotating;

[0056] When the adjusting member 43 is rotated to drive the adjusting tube 4 to rotate at a certain angle, the two top plates 25 can be expanded outward from the groove 24 of the tooth pad body 21. Since the upper and lower teeth of the patient are occluded on the two top plates 25, the top plates 25 will be subjected to the pressure of occlusion. In order to realize the hovering function of the top plates 25 after being expanded, a sleeve 44, a baffle 47 and a spring 45 are provided in the area of ​​the hole 28 of the tooth pad body 21. When the spring 45 applies a thrust to the sleeve 44 in the direction of the adjusting member 43, since a block 46 is provided on the outer wall of the sleeve 44, the block 46 will move with the movement of the sleeve 44 in the slide groove 29 on the inner wall of the hole 28 of the tooth pad body 21. The slide groove 29 can provide a linear guide for the block 46, so that the entire sleeve 44 can only move toward the adjustment member 43 and the tooth pad body 21, and cannot rotate. Therefore, when the multiple latch teeth 48 on the baffle plate 47 and the multiple latch teeth 48 on the adjustment member 43 are engaged with each other, the baffle plate 47 will limit the rotatable state of the adjustment member 43, so that the adjustment member 43 cannot rotate in a natural state, thereby forming a locking function for the state of the adjustment tube 4 and the two clamping rings 41 after the rotation adjustment is completed, thereby preventing the two top plates 25 from retracting into the groove 24 of the tooth pad body 21 when the pressure is applied by the patient's teeth.

[0057] When it is necessary to rotate the adjusting tube 4, the baffle 47 can be pushed toward the tooth pad body 21, causing the sleeve 44 to squeeze the spring 45 and shrink, so that the multiple latch teeth 48 on the baffle 47 are separated from the multiple latch teeth 48 on the adjusting member 43, thereby releasing the rotation restriction of the adjusting member 43, so that the adjusting member 43 can be rotated, and after the rotation of the adjusting member 43 is completed, the baffle 47 can be released immediately, so that the spring 45 loses the squeeze and rebounds to the expanded state, thereby driving the sleeve 44 and the baffle 47 to drive the latch teeth 48 to contact the latch teeth 48 on the adjusting member 43 again to form a locking function. During operation, it is only necessary to push the baffle 47 to realize the release of the rotation restriction function of the adjusting member 43, which has the effect of simple operation and can be better applied to nursing operations in modern clinical medicine.

[0058] Secondly, in the present patent application, with respect to the design of the baffle plate 47 and the multiple latch teeth 48 on the adjusting member 43, the baffle plate 47 and the multiple latch teeth 48 on the adjusting member 43 can be set as two opposite sets of ratchet teeth, so as to achieve the single-direction rotation restriction of the adjusting member 43, refer to the attached Figure 8 and 9As shown, taking the clockwise direction of the adjusting member 43 as an example when the two sets of ratchets are engaged with each other in the locked state, when restricting the clockwise rotation of the adjusting member 43, it can prevent the two top plates 25 from retracting in the natural state after expansion, thereby preventing the upper and lower teeth of the patient from suddenly hitting the area around the groove 24 of the mouthguard main body 21 due to the retraction of the top plates 25, and avoiding damage to the patient's teeth; when it is necessary to expand the top plates 25, the adjusting member 43 can be directly rotated without worrying about the two sets of ratchets forming mutual engagement restrictions. In actual operation, only when reducing the opening amplitude of the patient's oral cavity, the baffle 47 is toggled to release the rotation restriction of the adjusting member 43, which can further reduce the corresponding operation steps when adjusting the opening amplitude of the patient's oral cavity.

[0059] In a further preferred embodiment, referring to the attached Figure 1 As shown in FIG. 3, a limiting ring 5 is sleeved outside the mouthguard main body 21 between the adjusting member 43 and the top plate 25. The outer shape of the limiting ring 5 matches the shape of the through groove 11 on the bottom plate 1; on the side of the limiting ring 5 extending towards the extension part 23 of the mouthguard main body 21, an anti - detachment ring 51 with a larger diameter than the through groove 11 is fixedly arranged; on the outer side edge of the limiting ring 5 and towards the edge part of the adjusting member 43, a thread 52 is provided; a hand - tightening member 53 is sleeved on the threaded part of the limiting ring 5, and a threaded groove 54 matching the thread 52 on the limiting ring 5 is arranged in the middle of the hand - tightening member 53;

[0060] By means of the limiting ring 5 and the hand - tightening member 53 arranged on the mouthguard main body 21, a detachable design can be formed between the top plate 25 and the mouthguard main body 21. In clinical applications, since the oral cavity and mouth shapes of each patient are different, various sizes of the mouthguard main body 21 and the top plate 25 can be prepared. Furthermore, in actual applications, different combinations of the mouthguard main body 21 and the bottom plate 1 with different sizes can be selected according to different patients to achieve the most suitable placement and enable the patient to obtain the most suitable tracheal intubation mouthguard;

[0061] After the through - groove 11 part on the bottom plate 1 is sleeved on the mouthguard main body 21 from the front side of the adjusting member 43 direction, the bottom plate 1 is slightly pressed so that the through - groove 11 part of the bottom plate 1 is sleeved on the limiting ring 5 and forms an abutment with the anti - detachment ring 51. Subsequently, the hand - tightening member 53 is sleeved from the front side of the bottom plate 1, so that the threaded - groove 54 part of the hand - tightening member 53 is sleeved on the thread 52 part of the limiting ring 5, and the hand - tightening member 53 is rotated so that the threaded groove 54 on the hand - tightening member 53 and the thread 52 on the limiting ring 5 form a threaded connection state, and until the hand - tightening member 53 abuts against the bottom plate 1. At this time, the hand - tightening member 53 and the anti - detachment ring 51 can form limits from the front and back sides of the bottom plate 1, enabling the bottom plate 1 to be stably fixed on the mouthguard body to form an integral structure;

[0062] Secondly, through the detachable design of the tooth pad body 21 and the base plate 1, when the tooth pad body 21 and the base plate 1 need to be cleaned inside the patient's oral cavity during clinical use, the base plate 1 can be removed without removing the tooth pad body, thereby avoiding blocking the patient's mouth, allowing medical staff to use cleaning tools normally to clean the patient's cavity, so that the tooth pad is always between the patient's teeth during the cleaning process without losing the protection of the endotracheal tube, and can prevent the patient from biting the endotracheal tube or causing occlusal damage to the endotracheal tube due to the removal of the tooth pad body, which can further improve the service life of the endotracheal tube after placement to reduce the risk of air leakage due to damage to the endotracheal tube.

[0063] In a further preferred embodiment, refer to the attached Figure 14 As shown, the cannula holder 3 comprises a first clamping member 31 and a second clamping member 32 of a C-shaped structure, wherein the first clamping member 31 is fixedly connected to the clamping groove 12 of the bottom plate 1, and the C-shaped opening of the first clamping member 31 extends toward the clamping groove 12 to the outer area of ​​the bottom plate 1, and the second clamping member 32 is located at the front side of the first clamping member 31, and a third clamping member 33 of a C-shaped structure is fixedly arranged on the outer side of the second clamping member 32, and the thickness of the third clamping member 33 is the same as the overall thickness of the first clamping member 31 and the second clamping member 32, and the bottom of the third clamping member 33 is rotatably connected to the outer side of the first clamping member 31, and the inner sides of the first clamping member 31 and the second clamping member 32 are both provided with a silicone coating;

[0064] In order to further strengthen the position of the endotracheal tube after being inserted into the clamping groove 12 of the bottom plate 1, a first clamping member 31 and a second clamping member 32 are provided. When the endotracheal tube is inserted, the third clamping member 33 can be rotated to drive the second clamping member 32 and the first clamping member 31 to be in a C-shaped corresponding state, so that the clamping groove 12 on the bottom plate 1 is aligned with the two protrusions 1. 3, so that the tracheal cannula can be smoothly inserted into the clamping groove 12 from between the two protrusions 13. When the tracheal cannula is inserted into the clamping groove 12, it will be within the C-shaped coverage range of the first clamping member 31 and the second clamping member 32. At this time, the third clamping member 33 can be rotated to drive the second clamping member 32 to rotate, so that the second clamping member 32 blocks the C-shaped opening area of ​​the first clamping member 31, thereby wrapping the outside of the tracheal cannula by the first clamping member 31 and the second clamping member 32, and the silicone coating arranged on the inner side of the first clamping member 31 and the second clamping member 32 can form a tight fit when contacting the outer wall of the tracheal cannula, thereby clamping and fixing the tracheal cannula, so that the tracheal cannula cannot be easily separated from the clamping groove 12 area on the bottom plate 1, thereby reinforcing the connection between the tracheal cannula and the tooth pad body;

[0065] Compared with using medical adhesive tape in current hospitals to tie the tracheal intubation and the bite block together, when disassembling the bite block, the bottom plate 1 and the tracheal intubation in this patent application, there is no need to repeatedly disassemble and assemble the medical adhesive tape, which saves time and effort in operation. Using medical adhesive tape not only easily causes the adhered parts to contaminate the patient's mouth and the hands of medical staff, but also in medical operations, medical tape is a disposable item. After disassembly, it needs to be replaced in time to ensure normal use and avoid contamination. Therefore, there will be a certain amount of waste of medical resources. However, this patent application does not require the use of medical tape, which can effectively save medical resources and is more in line with modern medical use.

[0066] In a further preferred embodiment, referring to the attached Figure 1 As shown, a first strap 14 and a second strap 15 are respectively arranged on both sides of the bottom plate 1; one end of the first strap 14 is fixedly connected to one of the protruding parts 13 at the clamping groove 12 on the bottom plate 1; an extension strap 16 is fixedly arranged on the other protruding part 13, and a hook-and-loop fastener rough surface is arranged on the inner side of the extension strap 16, and a hook-and-loop fastener hook surface that can be adhesively connected to the hook-and-loop fastener rough surface on the extension strap 16 is arranged on the outer side of the first strap 14 near the clamping groove 12; the second strap 15 is located on the side of the bottom plate 1 where the clamping groove 12 is not provided, and one end of the second strap 15 is fixedly connected to the bottom plate 1; a hook-and-loop fastener hook surface is arranged on the inner side of the end of the first strap 14 that is not connected to the bottom plate 1, and a hook-and-loop fastener rough surface that can be adhesively connected to the hook-and-loop fastener hook surface on the first strap 14 is arranged on the outer side of the end of the second strap 15 where it is connected to the bottom plate 1;

[0067] In order to facilitate the fixation of the bite block body and the tracheal intubation to the patient's mouth, a first strap 14 and a second strap 15 are arranged on both sides of the bottom plate 1. During use, the first strap 14 and the second strap 15 can be covered towards the back of the patient's head and adhesively connected to each other through the hook-and-loop fastener; when the tracheal intubation needs to be placed in the clamping groove 12 on the bottom plate 1, the extension strap 16 can be lifted. After the tracheal intubation is placed in the clamping groove 12, the extension strap 16 can be immediately covered on the first strap 14, so that the extension strap 16 and the first strap 14 are adhesively connected through the hook-and-loop fastener, and thus the wearing of the bottom plate 1 on the patient's mouth can be completed.

[0068] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
