Description

Technical Field

[0001] This utility model relates to the field of medical devices for oral treatment, and in particular to an oral cannula fixation device. Background Technology

[0002] The statements in this section are merely to provide background information related to the disclosure of this utility model and do not necessarily constitute prior art.

[0003] In clinical medical practice, oral tube fixation devices are crucial for endotracheal intubation, gastric tube insertion, and various other tube insertion procedures. Oral tube fixation devices effectively maintain tube stability, reducing the risk of tube displacement due to patient movement or other factors. For patients undergoing general anesthesia or requiring mechanical ventilation due to respiratory dysfunction, stable fixation of the endotracheal tube is particularly critical. However, currently widely used fixation methods have several shortcomings:

[0004] (1) Traditional tape fixation methods have limitations because the adhesiveness of the tape may decrease due to moisture from the patient's oral secretions or sweat, which can lead to loosening and displacement of the intubation tube, thus affecting ventilation. In the worst case, this may even lead to tube dislodgement, resulting in serious medical accidents;

[0005] (2) Some fixation devices have complex structures and complicated installation processes, requiring professional skills and rich experience, and placing high demands on operators. In emergency situations and rapid intubation, the complex operating procedures make it difficult to install and adjust quickly and accurately, thus wasting valuable medical time;

[0006] (3) Many oral intubation fixation devices fail to adequately consider patient comfort in their design. The use of rigid materials and the lack of adaptability to different facial contours and oral structures can easily lead to pressure injuries to the facial skin and oral mucosa, thereby exacerbating patient suffering and increasing the likelihood of complications. In addition, these problems may also interfere with the patient's breathing. For critically ill patients, insufficient comfort is particularly critical, as it may affect the patient's psychological state and recovery process;

[0007] (4) Most of the cannula fixators currently on the market are designed for specific models or specifications, making it difficult to fix multiple cannulas simultaneously (see Appendix). Figure 4 The lack of versatility means that in clinical practice, doctors may have to keep multiple models of fixators on hand, increasing medical costs and the burden of inventory management.

[0008] The existing oral fixation devices mainly have the following technical problems:

[0009] ① Insufficient stability: The fixation of the intubation tube may become unstable due to external factors such as oral secretions and patient movement, which may cause the intubation tube to shift or fall off. This may have a negative impact on the ventilation effect and may lead to dangerous conditions such as hypoxia in patients.

[0010] ② Insufficient comfort: Traditional intubation fixation devices are usually made of hard plastic, which may cause problems such as pressure sores inside the mouth, facial discomfort and headaches after prolonged use;

[0011] ③ Applicability limitations: Most intubation fixators on the market are specifically designed and only applicable to specific models or specifications of intubation tubes. This limitation forces medical personnel to prepare multiple models of fixators for clinical use, which not only increases the complexity of operation but also increases inventory costs;

[0012] ④ Single function: Traditional oral cannulation fixation devices are limited to the function of cannulation and cannot simultaneously help patients keep their mouths stably open during oral surgery or examination. Utility Model Content

[0019] In this technical solution, the side of the push-pull slide that provides the sliding grip is also provided with a gripping part, which is one or a combination of gripping holes, gripping grooves, and gripping protrusions.

[0020] In this technical solution, a vertical pressing plate is provided at the bottom or top of the geared track. A pressing connection part is arranged on the vertical pressing plate, and a threaded locking support column is provided in the pressing connection part. One end of the threaded locking support column is close to or away from the geared track.

[0021] In this technical solution, the oral fixation support plate is also connected to an elastic strap.

[0022] In this technical solution, the jaw support device further includes an anterior jaw support structure, a left jaw support structure, and a right jaw support structure.

[0023] In this technical solution, the jaw support device also includes a tongue depressor structure disposed at the bottom of the left jaw support structure and the right jaw support structure.

[0024] In this technical solution, the left and right alveolar support structures are symmetrically arranged on the left and right, and both the left and right alveolar support structures are composed of an elastic support body and alveolar occlusal structures arranged at the top and bottom of the elastic support body.

[0025] In this technical solution, the elastic support is composed of at least one X-shaped structural support.

[0026] In this technical solution, the dental support device and / or oral fixation support plate is made of thermoplastic elastomer TPE, which not only has excellent strength and toughness, but also ensures gentleness to the oral mucosa.

Detailed Implementation

[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the combination or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, in the description of the embodiments of this utility model, the positional relationships of devices such as "upper," "lower," "front," "rear," "left," and "right" in all figures are based on... Figure 1 As the standard.

[0051] like Figure 1 As shown, the oral intubation fixation device includes a jaw support device 10 and an oral fixation support plate 20, and also includes an intubation channel 60 that passes through the jaw support device 10 and the oral fixation support plate 20. The oral fixation support plate 20 is located on the top and / or bottom of the intubation channel 60 on the outer side of the oral cavity and is provided with a geared track 21. The geared track 21 supplies a push-pull slide 40 to engage with it to move away from or towards the side of the intubation channel 60. This allows the push-pull slide 40 and the other side of the intubation channel 60 to hug and press the treatment trachea in the intubation channel 60 together, which can prevent the treatment trachea 80 from shaking and causing airway obstruction in the patient. This ensures that the patient's airway remains open during anesthesia, emergency treatment or intensive care, and prevents the intubation tube from slipping and causing airway obstruction, thereby avoiding hypoxia and suffocation.

[0052] The process of using an oral cannula fixator:

[0053] First, position the patient's mouth in a semi-open position. Then, gently insert the oral intubation fixator into the oral cavity. During insertion, ensure that the alveolar support devices on both sides of the oral intubation fixator are compatible with the patient's upper and lower dental arches. Then, slowly push it into the oral cavity. The shape and design of the alveolar support devices open the patient's upper and lower teeth, allowing the upper incisors to rest on the upper support surfaces of the anterior alveolar support structure 11, the left alveolar support structure 12, and the right alveolar support structure 13. During this process, the tongue depressor simultaneously presses down on the tongue, completing the oral cavity opening action. At this time, endoscopic examination and pre-operative examinations for oral surgery can be performed. When tracheal intubation or other surgeries are required, insert the tube, insert the push-pull slide into the slide fixing slot, secure the tube, and then tighten the threaded locking support post. After completing the specific surgery, remove the oral intubation fixator.

[0054] One embodiment of the use of the push-pull slide 40: After inserting the trachea into the mouth, by holding the gripping part 43, the push-pull slide 40 is pushed into the edge slide rail 23. The geared track 21 and the toothed sliding part 44 begin to mesh with each other, causing the push-pull slide 40 to move left and right, driving the clamping and pressing structure 42 and the support plate clamping structure 22 to clamp the trachea that needs to be fixed. In order to prevent the push-pull slide 40 from dislodging, the threaded locking support column 30 is tightened, squeezing the geared track 21. The pressure is used to firmly clamp the toothed sliding part 44 and the geared track 21. At that time, the push-pull slide 40 completely locks the trachea and will not shake.

[0055] In at least one embodiment, such as Figure 1 , Figure 3 as well as Figure 11 As shown, the push-pull slide 40 has a clamping opening 41 on the side facing the intubation channel 60, and a clamping and pressing structure 42 is provided at the innermost side of the clamping opening 41 to press the trachea in the intubation channel 60 when the clamping opening 41 of the push-pull slide 40 clamps the trachea.

[0056] In at least one embodiment, Figure 3 It is also shown that the oral cavity fixation support plate 20 is provided with a support plate clamping structure 22 on one side of the clamping port 41 of the push-pull slide 40, which further clamps the trachea in the bidirectional insertion channel 60. The push-pull slide 40 is also provided with a toothed sliding part 44 at the corresponding gear track 21, which further makes the push-pull slide 40 more stable during the adjustment process.

[0057] In at least one embodiment, the clamping and pressing structure 42 and the support plate clamping structure 22 are respectively provided with protruding structures on the side facing the intubation channel 60. The protruding structure is one or more sharp protruding structures, which further clamp the trachea in the intubation channel 60, increase the degree of clamping of the trachea, prevent instability caused by external forces such as gas delivery or accidental contact, and improve its stability during operation.

[0058] In at least one embodiment, such as Figure 1 and Figure 8 As shown, the oral cavity fixation support plate 20 is also provided with an edge-sealed slide rail 23 on the other side of the geared track 21, which is used to enhance the stability of the sliding of the push-pull slide 40 and can effectively prevent it from falling off or veering during sliding.

[0059] In at least one embodiment, Figure 10 As shown, the side of the push-pull slide 40 that provides the sliding grip is also provided with a gripping part 43. The gripping part 43 is one or a combination of gripping holes, gripping grooves, and gripping protrusions, so that doctors can quickly locate the operation site and perform treatment when using it.

[0060] In at least one embodiment, such as Figure 1 and Figure 6 As shown, the geared track 21 is further provided with a vertical pressing plate 25 at its bottom or top. A pressing connection portion 26 is arranged on the vertical pressing plate 25, and a threaded locking support column 30 is provided within the pressing connection portion 26. One end of the threaded locking support column 30 is close to or away from the geared track 21, enabling the air tube 80 to be pressed and adjusted from the bottom of the geared track 21, improving the stability and safety performance of the oral fixation device. This allows adjustment of the meshing tightness between the geared track 21 and the push-pull slide 40, thereby adjusting the pressing of the air tube within the insertion channel 60 from top to bottom by the push-pull slide 40. More specifically, in the specific implementation process, the vertical pressing plate 25 of the oral fixation support plate 20 is set as an elastic body structure with a certain degree of deflection, so that the threaded locking support column 30 can be moved away from or close to the bottom of the geared track 21 to press and adjust the air tube 80.

[0061] In at least one embodiment, Figure 8 It can also be seen that the oral fixation support plate 20 is also connected to the elastic strap 50 through the connection port 24 to fix the patient's head, thereby realizing the fixed connection between the patient's head and the oral fixation support plate 20. In the specific connection process, one or more elastic straps 5 with adjustable length are usually used for connection, which is convenient for adjustment.

[0062] In at least one embodiment, the jaw support device 10 further includes an anterior jaw support structure 11, a left jaw support structure 12, and a right jaw support structure 13. The tongue depressor structure 14 is used to press the tongue down to prevent irregular tongue movement from affecting the treatment and to improve the treatment effect. This achieves all-round support for the anterior jaw, left jaw, and right jaw of the oral cavity to ensure a smoother treatment in the patient's oral cavity.

[0063] In at least one embodiment, such as Figure 2 , Figure 4 and Figure 9 As shown, the jaw support device 10 also includes a tongue depressor 14 located at the bottom of the left jaw support structure 12 and the right jaw support structure 13, which further presses the tongue at the bottom of the intubation channel 60 to prevent tracheal sloshing caused by tongue movement.

[0064] In at least one embodiment, such as Figure 6 , Figure 7 and Figure 9 , Figure 10 As shown, the left jaw support structure 12 and the right jaw support structure 13 are symmetrically arranged on the left and right sides, and each is composed of an elastic support body 122 and alveolar occlusal structures 121 arranged on the top and bottom of the elastic support body 122. This provides sufficient support for the upper and lower teeth on the left and right sides, improving the stability of the oral cavity during treatment. The design of this structure has the following advantages: on the one hand, it ensures that the jawbone can be reasonably supported; on the other hand, after support, the elastic support body can provide sufficient elasticity and toughness for the teeth, providing a certain degree of comfort for the patient. At the same time, alveolar occlusal structures 121 are respectively provided on the upper and lower surfaces of the left jaw support structure 12 and the right jaw support structure 13. The shape of the alveolar occlusal structure 121 is set as several parallel flexible grooves, which facilitates single-row occlusal fixation, prevents slippage, and improves the stability of the upper and lower parts of the jawbone in the oral cavity.

[0065] In at least one embodiment, such as Figure 10 As shown, the elastic support 122 is composed of at least one X-shaped structure support, which has a good elastic effect and can ensure both comfort and strength support. The number of X-shaped structure supports can be 1, 2, 3, 4, etc., which facilitates active biting of the oral cavity, and at the same time can provide sufficient flexibility and comfort for oral cavity support, thereby ensuring that the support block can have both good support elasticity and sufficient strength.

[0066] In at least one embodiment, the dental support device 10 and / or oral fixation support plate 20 are made of thermoplastic elastomer.

[0067] like Figure 9 , Figure 10The illustrated jaw support device 10 includes an anterior jaw support structure 11, a left jaw support structure 12, and a right jaw support structure 13 connected as a single unit. The device also includes a tongue depressor 14 located at the bottom of the left and right jaw support structures 12 and 13, and an intubation channel 60 and a pharyngeal channel 70 located between the anterior jaw support structure 11, the left jaw support structure 12, and the right jaw support structure 13. The intubation channel 60 and the pharyngeal channel 70 are separated by a partition plate 16. This design facilitates tracheal compression and fixation of the intubation channel 60, and also works in conjunction with the tongue depressor 14 during the tracheal compression period. The intubation channel 60 supplies air to the patient's mouth, while the pharyngeal channel 70 assists in natural exhalation. The structure of the tongue depressor 14 is as follows... Figure 5 and Figure 9 As shown, its overall length meets the requirement of being able to press down the entire tongue and prevent the tongue from curling up. The tongue pressing structure 14 includes an arc-shaped tongue pressing part, which is tightly connected to the tooth support assembly and the insertion tube fixing and locking assembly by a connecting part, so as to quickly connect to the jaw support device 10.

[0068] The design of the anterior jaw support structure 11 allows the dentist to ensure the patient's upper incisors are positioned on the upper incisor support block by inserting their fingers through the gap at the top of the fixator, preventing the risk of the trachea being bitten during intubation and causing tube obstruction. The lower surface of the tongue depressor structure 14 presses against the patient's tongue surface to prevent the tongue from interfering with the intubation view and causing the tube to shift during intubation.

[0069] In at least one embodiment, the left alveolar support structure 12 and the right alveolar support structure 13 are symmetrically arranged on the left and right sides, and both the left alveolar support structure 122 and the right alveolar support structure 13 are composed of an elastic support body 122 and an alveolar occlusal structure 121 arranged on the top and bottom of the elastic support body 122, thereby providing sufficient support for the upper and lower teeth on the left and right sides and improving the stability of the oral cavity during treatment.

[0070] The alveolar occlusal structure 121 of the left alveolar support structure 12 and the right alveolar support structure 13 can ensure the stability of the entire tooth support block in the oral cavity.

[0071] In at least one embodiment, the elastic support 122 of the left jaw support structure 12 and the right jaw support structure 13 is composed of at least one X-shaped structure support, which facilitates active biting of the oral cavity and provides sufficient flexibility and comfort for oral cavity support.

[0072] In at least one embodiment, such as Figure 10As shown, the jaw support device 10 also includes a fixed support plate 15 connected to the outside of the oral cavity of the anterior jaw support structure 11. The fixed support plate 15 is used to assist the anterior jaw support structure 11 in fixing the oral cavity, which is convenient for treating the oral cavity or pharynx. The fixed support plate 15 is also used to connect with other structures to fix and support the oral cavity.

[0073] In at least one embodiment, the dental support device 10 is made of thermoplastic elastomer.

[0074] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
