Description

Technical Field

[0001] The invention relates to the technical field of medical equipment and peripheral supporting facilities thereof, in particular to a tracheal tube fixer. Background Art

[0002] An endotracheal tube is a medical device that is inserted into the patient's trachea and / or bronchus to establish a temporary artificial breathing channel for the patient. The safe fixation of the oral endotracheal tube is the guarantee for maintaining effective ventilation of the patient after successful intubation. The endotracheal tube needs to be kept in a fixed position without displacement.

[0003] At present, the fixation of tracheal tubes in clinical practice is generally performed by placing a dental pad partially in the patient's mouth, then tying the dental pad and the tracheal tube together with tape and sticking it on the face. The dental pads widely used in clinical practice not only have problems such as unstable fixation and possible damage to the oral cavity, but also the tape is prone to not being firmly adhered and the patient's skin being allergic to the tape. In addition, during maxillofacial surgery, disinfectant or blood in the surgical area and oral secretions will soak the tape, reducing the viscosity of the tape, or the tape stuck on the face will fall off, affecting the fixation effect, and even causing the tracheal tube to fall off, threatening the patient's life safety.

[0004] A Chinese patent with publication number CN221751867U discloses a new type of medical endotracheal tube fixer, which includes an endotracheal tube body, fixed strips are fixedly connected on the left and right sides of the endotracheal tube body, sliding protrusions are arranged on the front and back sides of the endotracheal tube body, the sliding protrusions are slidably connected with sliding rings, and an airbag is fixedly connected on the outside of the sliding ring. A fixed structure is formed by arranging an airbag, a sliding ring, a ventilating tube, a connecting tube, a one-way valve and a cover, and the airbag can be inflated through the ventilating tube, so that the airbag can be fixed in the patient's mouth to prevent the endotracheal tube from loosening. The inflatable endotracheal tube fixer needs to be repeatedly inflated and deflated to adjust the pressure, and the operation is cumbersome. There is a risk of blockage in the one-way inflation valve, and the airbag may leak due to tooth wear. If used improperly, it may also cause small parts to fall off, resulting in the risk of foreign matter in the esophagus or trachea.

[0005] Therefore, how to change the current situation of poor endotracheal tube fixation effect and complicated operation in the prior art has become an urgent problem to be solved by those skilled in the art. Summary of the invention

In practical applications, other types of temperature monitoring elements may also be selected; it should be explained here that the working principles of the temperature monitoring element and the body temperature display screen 6 are conventional means for those skilled in the art and will not be described in detail here. In other specific embodiments that can be implemented by the present invention, the monitoring unit may also be provided with other types of monitoring elements to monitor other physiological parameters of the user, so as to enhance the monitoring function of the monitoring unit and meet various different monitoring needs.

[0045] Specifically, in order to further improve the safety factor of the bite pad unit, a bite buffer layer is provided at one end of the bite pad body 1 where the temperature monitoring element is provided, that is, the bite buffer layer is provided on the part of the bite pad body 1 located below the bite pad limiting plate 5. The bite buffer layer is made of elastic material. In actual applications, the bite buffer layer can be made of silicone material to avoid damage to the oral cavity of the user, which is beneficial to improving the user experience.

[0046] It should also be noted that the dental pad unit also includes an ear hook 7, which can be connected to the fixing belt 2, so that the fixing belt 2 cooperates with the dental pad body 1 to ensure the fixing effect of the fixer and prevent the tracheal tube from shifting. The ear hook 7 and the tracheal tube buckle 3 are both located on the side of the dental pad limit plate 5 away from the temperature monitoring element; in actual operation, the fixing belt 2 can use an elastic rope, which is tied to the ear hook 7 after passing around the user's head, to ensure the fixing effect while improving the convenience of operation. In order to enhance the fixing effect, multiple sets of fixing belts 2 can be set, and the number of ear hooks 7 is also set to multiple sets. The ear hooks 7 are set around the dental pad body 1 to improve the uniform force of the dental pad body 1, while ensuring the uniformity of fixing, and avoiding the discomfort of the fixer to the user as much as possible.

[0047] In other specific embodiments that can be realized by the present invention, the fixing strap 2 includes a supporting portion 8 and binding portions 9 located at both ends of the supporting portion 8, the width of the supporting portion 8 is wider than that of the binding portion 9, both sides of the supporting portion 8 are Velcro surfaces, the end of the binding portion 9 close to the supporting portion 8 is the Velcro surface, and the end of the binding portion 9 away from the supporting portion 8 is the Velcro hook surface, and the two binding portions 9 are both provided with hanging rings 10, and the hanging rings 10 can be connected to the ear hooks 7, and the Velcro hook surface of the binding portion 9 can bypass the hanging rings 10 and be hooked and connected to the Velcro surface of the binding portion 9 or the supporting portion 8; the number of fixing straps 2 is multiple groups, and the hanging rings 10 correspond to the ear hooks 7 one by one. Taking the setting of two sets of fixing belts 2 as an example, one of the fixing belts 2 is unfolded and placed on the user's pillow, and the other fixing belt 2 is placed behind the user's neck. The hanging ring 10 is hooked on the ear hook 7. The binding parts 9 at both ends of the fixing belt 2 are fixed to themselves or the supporting plate after passing through the hanging ring 10. The Velcro fur surface is connected with the hook surface, which improves the flexibility and adaptability of the fixing belt 2, adapts to users of various body shapes, and the fixing operation is convenient. In addition, the supporting part 8 of the fixing belt 2 is relatively wide, which increases the contact area between the fixing belt 2 and the user, improves the uniformity of the force applied to the user during fixing, and improves the comfort of fixing. In actual applications, the shape and specifications of the hanging ring 10 can be selected according to actual working conditions, such as T-shaped hanging ring, triangular hanging ring, circular hanging ring, etc., to meet different binding and connection requirements and improve the flexibility and adaptability of the fixing belt 2.

[0048] More specifically, when the tracheal tube buckle 3 is connected to the bite block unit, the tracheal tube buckle 3 is plug-connected to the bite block body 1, the plug-connected connection is tight, and the disassembly and assembly operation is convenient. In order to improve the adaptability of the fixator, a variety of specifications of tracheal tube buckles 3 can be set, and the tracheal tube buckle 3 of the appropriate specification can be selected according to the different specifications of the tracheal tube. In addition, in actual applications, the tracheal tube buckle 3 and the bite block body 1 can also adopt other connection methods, such as threaded connection, etc., to facilitate disassembly and assembly.

[0049] In this specific embodiment, the dental pad body 1 is connected to a splicing block 11, and the tracheal tube buckle 3 is connected to a splicing joint 12. The splicing block 11 has a splicing groove adapted to the splicing joint 12, and the splicing joint 12 is plugged and connected to the splicing block 11 using the splicing groove; the splicing joint 12 can be inserted into the splicing groove to realize the plug-in connection between the splicing joint 12 and the splicing block 11. The splicing groove is a top opening structure. On the premise of allowing the splicing joint 12 to be inserted smoothly, the extreme plug-in position of the splicing joint 12 is limited, thereby improving the plug-in connection reliability of the splicing joint 12 and the splicing block 11.

[0050] In order to further improve the plug-in firmness of the splicing joint 12 and the splicing block 11, the outer side wall of the splicing joint 12 of the present invention is provided with a limiting element, and the limiting element is a protruding structure facing the axis direction of the splicing groove, and the side wall of the splicing groove is provided with a limiting groove that matches the limiting element. When the splicing joint 12 is plugged and connected to the splicing block 11, the limiting element cooperates with the limiting groove to achieve a similar snap-in effect, thereby enhancing the connection firmness of the splicing joint 12 and the splicing block 11. It should also be noted here that in actual applications, limiting elements and / or limiting grooves can be provided on the splicing joint 12 and / or the splicing groove, that is, one or both of the limiting elements and limiting grooves (limiting elements and limiting grooves) can be provided on the splicing joint 12 and the splicing groove, thereby enhancing the connection firmness of the dental pad body 1 and the tracheal tube buckle 3, while improving the flexibility and adaptability of the fixator.

[0051] Furthermore, the inner wall of the tracheal tube buckle 3 of the present invention is provided with a clamping protrusion 13, and the clamping protrusion 13 can abut against the tracheal tube to clamp the tracheal tube. The provision of the clamping protrusion 13 can increase the friction between the tracheal tube buckle 3 and the tracheal tube, effectively enhance the fixing effect of the tracheal tube buckle 3 on the tracheal tube, ensure the stability of the tracheal tube, and improve the adaptability of the tracheal tube buckle 3 to tracheal tubes of different specifications. In this specific embodiment, the abutting surface of the clamping protrusion 13 and the tracheal tube is an arc surface and has an anti-slip structure layer. The clamping protrusion 13 is an arc surface structure that can effectively protect the tracheal tube and prevent the clamping protrusion 13 from damaging the tracheal tube. The anti-slip structure layer is made of elastic material, and can be made of silicone material, which further enhances the clamping and fixing effect of the clamping protrusion 13, prevents the tracheal tube from sliding and dislocating, and provides effective protection for the tracheal tube.

[0052] In this specific embodiment, the clamping protrusion 13 is a columnar structure parallel to the axis direction of the tracheal tube buckle 3, the number of the clamping protrusions 13 is multiple groups, and the clamping protrusions 13 are arranged circumferentially around the axis of the tracheal tube buckle 3, while stably clamping and fixing the tracheal tube, the force uniformity of the tracheal tube is improved. In other specific embodiments that can be realized by the present invention, the clamping protrusion 13 can also be a spherical protrusion structure, a convex point structure or other structures to meet different clamping and fixing requirements and improve the flexibility and adaptability of the tracheal tube buckle 3.

[0053] Furthermore, there are latch teeth 14 on both sides of the opening of the tracheal tube buckle 3, one of which is located on the inner wall of the tracheal tube buckle 3, and the other is located on the outer wall of the tracheal tube buckle 3, and the two latch teeth 14 can be engaged to block the opening of the tracheal tube buckle 3. After the tracheal tube enters the slot 4, in order to enhance the clamping and fixing effect of the tracheal tube buckle 3 on the tracheal tube, the opening of the tracheal tube buckle 3 can be closed by engaging the two latch teeth 14 with each other, so as to ensure the stable fixation of the tracheal tube, and further enhance the adaptability of the tracheal tube buckle 3 to tracheal tubes of different specifications. In this specific embodiment, the latch teeth 14 are inclined, and the inclination directions of the two latch teeth 14 are opposite to enhance the reliability of the engagement of the two latch teeth 14. In order to achieve the closure of the opening of the tracheal tube buckle 3, the tracheal tube buckle 3 can be made of a material with a certain elasticity, so that the tracheal tube buckle 3 can smoothly produce elastic deformation when the latch teeth 14 are used to close the opening.

[0054] In order to improve the operating convenience of the tracheal tube buckle 3, the tracheal tube buckle 3 is also connected to a force-bearing plate 15, and the number of the force-bearing plates 15 is two groups, and the two force-bearing plates 15 are respectively located on the outer walls on both sides of the opening of the tracheal tube buckle 3; a side of the outer wall of the tracheal tube buckle 3 is provided with a clamping tooth 14, and the force-bearing plate 15 is located on the side of the opening of the tracheal tube buckle 3 away from the clamping tooth 14; the provision of the force-bearing plate 15 facilitates the operator to apply force to the tracheal tube buckle 3, so as to realize the clamping and fixing of the tracheal tube by the tracheal tube buckle 3, and at the same time facilitates the opening and closing operation of the tracheal tube buckle 3. In practical applications, the opening of the tracheal tube buckle 3 has a guiding inclined surface inclined toward the latch teeth 14. When the force plate 15 is used to apply a force to the tracheal tube buckle 3 to deform it, the guiding inclined surfaces at the opening of the tracheal tube buckle 3 come into contact and provide guidance for the elastic deformation of the tracheal tube buckle 3, so that the two latch teeth 14 can be engaged, thereby improving the convenience of operation. At the same time, when the tracheal tube is pushed into the slot 4 from the opening of the tracheal tube buckle 3, the guiding inclined surface can also play a role in guiding the tracheal tube.

[0055] The tracheal tube fixer 100 of this embodiment uses the clamping groove 4 of the tracheal tube buckle 3 to fix the tracheal tube, thereby enhancing the fixing effect of the tracheal tube and effectively preventing the tracheal tube from shifting; the tracheal tube buckle 3 adopts a non-closed structure, which is suitable for fixing tracheal tubes of different specifications, and is easy to operate, so as to quickly fix the tracheal tube. The tracheal tube fixer 100 of the present invention can monitor the user's body temperature data in real time while fixing the tracheal tube, and realize body temperature visualization.
