Description

Technical Field

[0001] This invention relates to endotracheal intubation technology, and more specifically to a dental protective sleeve for endotracheal intubation. Background Technology

[0002] During surgical anesthesia, an endotracheal tube needs to be inserted through the mouth. However, since the patient's teeth are naturally closed after anesthesia, medical staff need to use a mouth support to open the patient's mouth before inserting the endotracheal tube. During anesthesia, the patient may bite off or flatten the endotracheal tube, affecting breathing and making the surgical procedure difficult.

[0003] Chinese patent CN222150677U discloses a dental protective sleeve for endotracheal tubes used in anesthesia, including an upper dental sleeve and a lower dental sleeve. The upper dental sleeve is provided with an upper alveolar bone that is adapted to the upper teeth, and the lower dental sleeve is provided with a lower alveolar bone that is adapted to the lower teeth, which solves the problem of endotracheal tubes being easily bitten off or flattened.

[0004] Existing dental protectors are mostly positioned by directly contacting the upper and lower braces with the teeth. However, their structural design does not fully consider the dental condition of special groups such as elderly patients. For elderly patients, teeth become loose and less secure due to aging. The current method of positioning by directly contacting the braces with the teeth will put a large load on the loose teeth. This not only makes it difficult to achieve stable wearing and positioning, but also easily aggravates the loosening of teeth and may even directly cause tooth damage. It cannot meet the safety needs of elderly patients for dental protection during tracheal intubation surgery. Summary of the Invention

[0005] The purpose of this invention is to provide a dental protective sleeve for endotracheal intubation, in order to solve the problem that the design of the dental protective sleeve in the prior art, which directly abuts against the teeth, puts too much load on elderly patients with loose teeth and is prone to tooth damage, thus failing to meet the problem of dental safety protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dental protective sleeve for endotracheal intubation, comprising a lower dental sleeve, both ends of which are fixedly connected to arc-shaped connectors, and an upper dental sleeve is fixedly connected to the end of the arc-shaped connector away from the lower dental sleeve. Both the lower and upper dental sleeves have placement grooves inside. The upper surface of the lower dental sleeve and the lower surface of the upper dental sleeve each have through grooves communicating with the placement grooves. A driving component and a limiting component are disposed inside the placement groove. A pressing component connected to the driving component is disposed inside the placement groove. An abutment component connected to the limiting component is disposed inside the placement groove.

[0007] The driving component includes a first slide rail fixedly connected to both sides of the middle of the bottom wall of the placement slot. A driving block is movably connected to the upper end of the first slide rail. A first limiting groove is opened at the lower end of the driving block. The first slide rail is slidably connected to the inner wall of the first limiting groove. A second mounting groove is opened on the side wall of the driving block. A pushing component is provided on the side wall of the driving block.

[0008] The limiting component includes a second push plate, one end of which has a drive groove. An installation plate is fixedly connected to the middle of the upper surface of the second push plate. Limiting posts are movably connected through both sides of the upper surface of the second push plate. The upper and lower ends of the limiting posts are fixedly connected to the top wall and the bottom wall of the placement groove, respectively.

[0009] Furthermore, the pressing assembly includes a third spring fixedly connected to the inner sidewall of the second mounting groove. One end of the third spring is fixedly connected to a second connecting plate, and the end of the second connecting plate away from the third spring is fixedly connected to a pressing block. A second limiting groove is provided at the lower end of the pressing block, and a second slide rail is movably connected to the inner wall of the second limiting groove. One end of the second slide rail is fixedly connected to a first slide rail.

[0010] Furthermore, the abutting component includes a plurality of third mounting slots evenly formed on the upper end of the mounting plate. A baffle is movably connected to the inner wall of the third mounting slot. A connecting post is fixedly connected to the middle of the upper surface of the baffle. Fourth springs are fixedly connected to both sides of the upper surface of the baffle. The upper ends of the fourth springs are fixedly connected to the top wall of the third mounting slot. An abutting block is fixedly connected to the upper end of the connecting post. The upper end of the abutting block passes through a through slot.

[0011] Furthermore, the upper surface of the first slide rail is evenly provided with multiple slots, the lower end of the drive block is provided with a first mounting slot, the top wall of the first mounting slot is fixedly connected with a first spring, the lower end of the first spring is fixedly connected with a locking block, the lower end of the locking block is provided with a rounded corner, and the two non-adjacent side walls at the slot port are respectively provided with rounded corners.

[0012] Furthermore, the lower and upper braces are respectively provided with sliding grooves on their sidewalls. The pushing assembly includes a first connecting plate fixedly connected to the sidewall of the driving block. The first connecting plate is slidably connected to the inner wall of the sliding groove. A first push plate is fixedly connected to the end of the first connecting plate away from the driving block. The sidewall of the first push plate away from the first connecting plate is arc-shaped. The sidewall of the first push plate away from the first connecting plate is provided with anti-slip texture.

[0013] Furthermore, airway grooves are respectively provided in the middle part of the upper surface of the lower brace and the lower surface of the upper brace, and airbags are provided in the inner wall of the airway grooves. Limiting plates are fixedly connected to the edges of the lower surface of the lower brace and the upper surface of the upper brace.

[0014] Furthermore, a second spring is movably sleeved on the side wall of the limiting post, and the upper and lower ends of the second spring are respectively fixedly connected to the top wall of the placement groove and the upper surface of the second push plate.

[0015] Furthermore, a gap is left between the side wall of the drive block away from the pushing component and the inner side wall of the placement groove, and one end of the mounting plate is provided with a rounded corner.

[0016] Furthermore, the lower end of the pressing block is provided with a rounded corner.

[0017] Furthermore, the side wall of the mounting plate is slidably connected to the inner wall of the through groove, and the width of the second push plate is greater than the width of the through groove.

[0018] Compared with existing technologies, the present invention provides a dental protective sleeve for endotracheal intubation. Through the linkage design of the abutment component and the limiting component, the positioning force point is transferred from the teeth to the gums. The abutment component adopts multiple dispersed abutment blocks, each of which is elastically floating through a fourth spring. It can independently adapt to the local morphology of the gums, forming a multi-point, elastic abutment effect. This avoids the force concentration caused by single-point hard contact and ensures positioning stability through a wide gum contact surface. At the same time, the second push plate of the limiting component guides smoothly along the limiting post. With the sliding cooperation of the mounting plate and the through groove, it ensures that the abutment block extends accurately and fits smoothly against the gums, avoiding direct pressure on loose teeth. This meets the core need for dental safety protection during endotracheal intubation surgery for special populations such as elderly patients.

[0019] Secondly, through the linkage structure of the drive component, the pressing component, and the airbag, an integrated design of tooth protection and tracheal restraint is achieved. The drive component drives the pressing block to move smoothly along the second slide rail, and the elastic thrust of the third spring presses the airbag, causing the airbag to inflate and wrap around the tracheal tube in the tracheal groove, effectively preventing the trachea from being bitten or flattened, and ensuring a smooth breathing channel. At the same time, the locking block of the drive component and the locking groove of the first slide rail form a positioning, which, together with the arc-shaped anti-slip design of the push component, not only facilitates medical staff to quickly complete the wearing and fixing operation, but also prevents the structure from shifting due to the patient's unconscious oral movement, greatly improving the convenience of operation and the reliability of use during the operation.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] To address the issue that the design of dental protective sleeves, which directly contact the teeth, can place excessive stress on elderly patients with loose teeth, potentially causing tooth damage and failing to meet the requirement of safe dental protection, please refer to [the relevant documentation / reference]. Figure 1 - Figure 8 The following preferred technical solutions are provided.

[0033] An embodiment of the present invention provides a dental protective sleeve for endotracheal intubation, including a lower dental sleeve 1, with arc-shaped connectors 11 fixedly connected to both ends of the lower dental sleeve 1, and an upper dental sleeve 12 fixedly connected to the end of the arc-shaped connectors 11 away from the lower dental sleeve 1. Both the lower dental sleeve 1 and the upper dental sleeve 12 have placement grooves 15 inside, and both the upper surface of the lower dental sleeve 1 and the lower surface of the upper dental sleeve 12 have through grooves 17 that communicate with the placement grooves 15. The placement grooves 15 are provided with a driving component 2 and a limiting component 3 inside, a pressing component 4 connected to the driving component 2 inside, and an abutting component 5 connected to the limiting component 3 inside.

[0034] The drive assembly 2 includes a first slide rail 21 fixedly connected to both sides of the middle of the bottom wall of the placement slot 15. A drive block 23 is movably connected to the upper end of the first slide rail 21. A first limiting groove 231 is opened at the lower end of the drive block 23. The first slide rail 21 is slidably connected to the inner wall of the first limiting groove 231. A second mounting groove 233 is opened on the side wall of the drive block 23. A push assembly 26 is provided on the side wall of the drive block 23.

[0035] The limiting component 3 includes a second push plate 31, one end of which has a drive groove 311. An mounting plate 32 is fixedly connected to the middle of the upper surface of the second push plate 31. Limiting posts 33 are movably connected through the two sides of the upper end of the second push plate 31. The upper and lower ends of the limiting posts 33 are fixedly connected to the top wall and bottom wall of the placement groove 15, respectively.

[0036] Specifically, the medical staff drives the push component 26 to drive the drive block 23. With the sliding cooperation between the first limiting groove 231 at the lower end of the drive block 23 and the first slide rail 21, the drive block 23 moves smoothly along the first slide rail 21. When the drive block 23 moves, one end of it abuts against the drive groove 311 of the second push plate 31 in the limiting component 3, pushing the second push plate 31 to slide upward along the limiting post 33. This, in turn, drives the mounting plate 32, which is fixedly connected to the second push plate 31, to extend upward along the inner wall of the through groove 17. At the same time, the drive block 23 synchronously drives the pressing component 4, realizing the linkage between the drive component 2, the limiting component 3, and the pressing component 4. Finally, the abutment component 5 at the upper end of the mounting plate 32 smoothly abuts against the patient's gums to complete the positioning.

[0037] The pressing assembly 4 includes a third spring 41 fixedly connected to the inner wall of the second mounting groove 233. One end of the third spring 41 is fixedly connected to a second connecting plate 42. The end of the second connecting plate 42 away from the third spring 41 is fixedly connected to a pressing block 43. A second limiting groove 44 is provided at the lower end of the pressing block 43. A second slide rail 45 is movably connected to the inner wall of the second limiting groove 44. One end of the second slide rail 45 is fixedly connected to the first slide rail 21.

[0038] Specifically, when the drive block 23 in the drive assembly 2 moves along the first slide rail 21 under the drive of the push assembly 26, the third spring 41 in the second mounting groove 233 on the side wall of the drive block 23 is subjected to a linkage force, pushing the second connecting plate 42 fixedly connected to it towards the airbag 14. The second connecting plate 42 simultaneously drives the pressing block 43 at the end. With the sliding cooperation between the second limiting groove 44 at the lower end of the pressing block 43 and the second slide rail 45, the pressing block 43 is smoothly guided to move along the second slide rail 45. Finally, the side wall of the pressing block 43 fits against the airbag 14, and the elastic thrust of the third spring 41 achieves stable pressing of the airbag 14, causing the airbag 14 to expand and tightly wrap the endotracheal tube, thus completing the limiting and fixing of the endotracheal tube.

[0039] The abutment component 5 includes a plurality of third mounting grooves 51 evenly opened on the upper end of the mounting plate 32. A baffle 52 is movably connected to the inner wall of the third mounting groove 51. A connecting post 53 is fixedly connected to the middle of the upper surface of the baffle 52. A fourth spring 54 is fixedly connected to both sides of the upper surface of the baffle 52. The upper end of the fourth spring 54 is fixedly connected to the inner top wall of the third mounting groove 51. An abutment block 55 is fixedly connected to the upper end of the connecting post 53. The upper end of the abutment block 55 passes through the through groove 17. In this embodiment, the abutment block 55 can be made of medical latex.

[0040] Specifically, when the driving block 23 in the driving assembly 2 pushes the second push plate 31 of the limiting assembly 3 to slide upward along the limiting post 33, the mounting plate 32 fixed on the upper surface of the second push plate 31 extends upward along the inner wall of the through groove 17. In the multiple third mounting slots 51 evenly opened at the upper end of the mounting plate 32, the fourth spring 54 pushes the corresponding baffle 52 towards the direction closer to the gum. The baffle 52 drives the end abutment block 55 to move upward synchronously through the connecting post 53, so that all abutment blocks 55 penetrate through the through groove 17. Since the multiple abutment blocks 55 are distributed in a dispersed manner, and each abutment block 55 can independently adapt to the local morphology of the gum under the elastic action of the fourth spring 54, it can form contact with different areas of the gum, avoiding the force concentration caused by single point contact, and covering a wider gum contact surface. Finally, it achieves full and stable contact between the multiple abutment blocks 55 and the gum, which not only ensures positioning stability but also reduces local pressure on the gum.

[0041] Multiple slots 22 are evenly provided on the upper surface of the first slide rail 21. A first mounting slot 232 is provided at the lower end of the drive block 23. A first spring 24 is fixedly connected to the top wall of the first mounting slot 232. A locking block 25 is fixedly connected to the lower end of the first spring 24. The lower end of the locking block 25 is provided with a rounded corner. The two non-adjacent side walls at the port of the slot 22 are respectively provided with rounded corners.

[0042] Specifically, when the pushing component 26 drives the driving block 23 to move along the first slide rail 21, the first spring 24 in the first mounting groove 232 at the lower end of the driving block 23 always applies a downward pushing force to the locking block 25. The rounded corner at the lower end of the locking block 25 cooperates with the rounded corner at the port of the locking groove 22 on the first slide rail 21, allowing the driving block 23 to slide smoothly. As the driving block 23 is linked to the limiting component 3, it pushes the mounting plate 32 and multiple abutment blocks 55 upward to extend and smoothly abut against the gums. At the same time, the linkage pressing component is also linked. 4. After the pressing block 43 moves and presses the airbag 14, the locking block 25 is locked into the corresponding slot 22 on the first slide rail 21 under the elastic force of the first spring 24. The position of the driving block 23 is fixed by the stable engagement of the locking block 25 and the slot 22, thereby indirectly realizing the positioning of the abutment block 55 after it abuts the gum, and the state of the pressing block 43 after pressing the airbag 14, so as to avoid the abutment block 55 from shifting or the pressing block 43 from falling off the airbag 14 due to external force or oral movement during use.

[0043] The lower brace 1 and the upper brace 12 are respectively provided with sliding grooves 16 on their side walls. The pushing component 26 includes a first connecting plate 261 fixedly connected to the side wall of the driving block 23. The first connecting plate 261 is slidably connected to the inner wall of the sliding groove 16. A first push plate 262 is fixedly connected to the end of the first connecting plate 261 away from the driving block 23. The side wall of the first push plate 262 away from the first connecting plate 261 is arc-shaped. The side wall of the first push plate 262 away from the first connecting plate 261 is provided with anti-slip texture.

[0044] Specifically, medical staff push the first push plate 262 on the sidewalls of the lower brace 1 and the upper brace 12. With the help of the first connecting plate 261 that slides with the slide groove 16, the driving block 23 in the driving assembly 2 moves smoothly along the first slide rail 21. This, in turn, links the limiting assembly 3 and the pressing assembly 4 to complete the gum contact and airbag 14 pressing action. At the same time, the end of the first push plate 262 away from the first connecting plate 261 adopts an arc-shaped sidewall design. This shape has no obvious force protrusion. When the patient's lips in the mouth contact the first push plate 262, no effective pushing force can be formed. This avoids the patient accidentally pushing the first push plate 262 due to unconscious oral movement during anesthesia, and prevents the driving block 23 from shifting, causing the contact block 55 to detach from the gum and the pressing block 43 to loosen. This increases the structural stability of the device during use.

[0045] Airway grooves 13 are respectively provided in the middle part of the upper surface of the lower brace 1 and the lower surface of the upper brace 12. An airbag 14 is provided on the inner wall of the airway groove 13. Limiting plates 18 are fixedly connected to the edges of the lower surface of the lower brace 1 and the upper surface of the upper brace 12.

[0046] Specifically, during the wearing of the device, the limiting plates 18 at the edges of the lower surface of the lower brace 1 and the upper surface of the upper brace 12 will form a limiting position with the corresponding parts of the oral cavity. The limiting plate 18 limits the installation position of the device, ensuring that the lower brace 1 is stably placed above the lower teeth and the upper brace 12 is accurately placed below the upper teeth. This allows the through grooves 17 on the lower brace 1 and the upper brace 12 to align with the corresponding areas of the gums, providing positional assurance for the subsequent abutment block 55 of the abutment component 5 to pass through the through groove 17 and smoothly abut against the gums. At the same time, the air bladder 14 on the inner wall of the tracheal groove 13 in the middle of the lower brace 1 and the upper brace 12 expands under the pressing action of the pressing component 4, which can tightly wrap the tracheal tube placed in the tracheal groove 13, thereby achieving auxiliary limiting of the trachea and preventing tracheal displacement. Finally, with the position limitation of the limiting plate 18 and the tracheal limiting of the air bladder 14, both the precise abutment of the abutment block 55 against the gums and the stable placement of the tracheal tube are ensured.

[0047] A second spring 34 is movably sleeved on the side wall of the limiting post 33. The upper and lower ends of the second spring 34 are fixedly connected to the top wall of the placement groove 15 and the upper surface of the second push plate 31, respectively. When the driving block 23 in the driving assembly 2 pushes the second push plate 31 of the limiting assembly 3, the second push plate 31 slides upward along the limiting post 33. At this time, the second spring 34, which is movably sleeved on the side wall of the limiting post 33, is compressed by the top wall of the placement groove 15 and the upper surface of the second push plate 31 and stores energy. When the use ends and the driving block 23 is reset under the reverse operation of the pushing assembly 26, the retracted second spring 34 releases elastic potential energy and applies a downward pushing force to the second push plate 31, causing the second push plate 31 to fall smoothly back to the initial position along the limiting post 33. The mounting plate 32, which is fixedly connected to the second push plate 31, is reset synchronously with the second push plate 31, thereby causing the abutment block 55 of the abutment assembly 5 to retract into the through groove 17, and finally realizing the automatic reset of the second push plate 31 and the mounting plate 32.

[0048] A gap is left between the side wall of the drive block 23 away from the push component 26 and the inner side wall of the placement groove 15. One end of the mounting plate 32 is rounded. During the operation of the device, a limiting post 33 needs to be installed in the placement groove 15 to ensure the smooth sliding of the second push plate 31. The gap reserved between the side wall of the drive block 23 away from the push component 26 and the inner side wall of the placement groove 15 provides sufficient space for the installation of the limiting post 33, avoiding conflict between the installation position of the limiting post 33 and the movement trajectory of the drive block 23. At the same time, the rounded corner at one end of the mounting plate 32 can ensure that the drive block 23 can smoothly push the second push plate 31 to move, thereby ensuring the linkage stability of the drive component 2 and the limiting component 3, and enabling the entire movement process to proceed without obstruction.

[0049] The lower end of the pressing block 43 is rounded. When the driving block 23 in the driving assembly 2 drives the third spring 41 and the second connecting plate 42 in the second mounting groove 233 to move in conjunction, the pressing block 43 moves towards the arc-shaped airbag 14 by means of the sliding cooperation between the second limiting groove 44 and the second slide rail 45. Since the lower end of the pressing block 43 is rounded, this structure can fit and conform to the surface of the arc-shaped airbag 14 on the inner wall of the tracheal groove 13, increasing the actual contact area between the pressing block 43 and the airbag 14, thereby more firmly wrapping the tracheal tube and ensuring the reliability of the tracheal limit.

[0050] The side wall of the mounting plate 32 is slidably connected to the inner wall of the through groove 17. The width of the second push plate 31 is greater than the width of the through groove 17. When the driving component 2 pushes the second push plate 31 of the limiting component 3 to slide upward along the limiting post 33, the mounting plate 32, which is fixedly connected to the second push plate 31, extends smoothly upward along the through groove 17 by means of the sliding cooperation between its side wall and the inner wall of the through groove 17. Since the width of the second push plate 31 is greater than the width of the through groove 17, when the mounting plate 32 moves upward to the maximum stroke, the second push plate 31 will be blocked by the edge of the port of the through groove 17 and cannot pass through the through groove 17. Thus, the second push plate 31 forms an axial limit on the mounting plate 32, effectively preventing the mounting plate 32 from detaching from the through groove 17 due to excessive extension. This ensures the connection stability between the mounting plate 32 and the abutment component 5, and ensures that the abutment block 55 can always accurately abut against the gum through the drive of the mounting plate 32, maintaining the integrity of the entire device linkage structure.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
