Abstract
Description
Technical Field
[0001] This utility model relates to the field of intubation fixation technology, and in particular to a nasotracheal intubation fixation device. Background Technology
[0002] Endotracheal intubation involves inserting a specially designed tube into the patient's trachea through the mouth or nose. This technique provides optimal conditions for airway patency, ventilation and oxygenation, airway suction, and prevention of aspiration. Emergency endotracheal intubation has become an important measure in cardiopulmonary resuscitation and the rescue of critically ill patients with respiratory dysfunction, playing a significant role in the resuscitation of critically ill patients. Nasal endotracheal intubation fixators are secured to the patient's head with straps. However, after prolonged use, the straps become soiled with the patient's sweat and secretions. Currently, the fixation straps of these devices are generally fixed, making them inconvenient to disassemble and replace, and unsuitable for long-term use. Therefore, we have introduced a new nasal endotracheal intubation fixator. Utility Model Content

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A nasotracheal intubation fixation device includes a fixation plate 1. A limiting mechanism 2 is fixedly installed on the middle part of the outer surface of the fixation plate 1. A connecting plate 3 is provided at the left and right ends of the fixation plate 1. A strap hole 4 is provided at the upper end of each of the two connecting plates 3. A strap-threading device 5 is movably installed inside the two strap holes 4. A first adhesive hook surface 6 is provided at the middle part of the left side and the middle part of the right side of the lower end of the fixation plate 1. An adhesive pad 7 is provided at the lower end of the fixation plate 1. A first adhesive rough surface 8 is provided on the upper left side and the upper right side of the outer surface of the adhesive pad 7. The adhesive pad 7 is movably bonded to the two first adhesive hook surfaces 6 through the first adhesive rough surface 8.
[0030] In this embodiment, the limiting mechanism 2 includes a limiting seat 21. A support block 22 is fixedly installed on the left side of the inner surface of the limiting seat 21. A screw 23 is movably installed through the middle right side of the outer surface of the limiting seat 21. A knob 24 is fixedly installed on the right end of the screw 23. A first limiting plate 25 is fixedly installed on the right end of the support block 22. A second limiting plate 29 is movably installed on the left end of the screw 23 through a movable sleeve. Protective pads 26 are provided on the inner surfaces of both the first limiting plate 25 and the second limiting plate 29. Balance bars 27 are movably installed through the front right side and the rear right side of the outer surface of the limiting seat 21. A stop block 28 is provided on the right end of each of the four balance bars 27. The left ends of the four balance bars 27 are fixedly connected to the right side of the outer surface of the second limiting plate 29. The positions of the first limiting plate 25 and the second limiting plate 29 are corresponding left and right. The first limiting plate 25 and the second limiting plate 29 are both arc-shaped structures.
[0031] The above solution involves inserting one end of the nasal tube into the limiting seat 21, positioning the nasal tube between the first limiting plate 25 and the second limiting plate 29. By manually rotating the knob 24, the second limiting plate 29 can be easily moved left and right. The cooperation of the four balance rods 27 ensures that the limiting plate 29 moves more smoothly, preventing the second limiting plate 29 from tilting during movement. When the second limiting plate 29 moves to the left until the inner protective pad 26 is tightly attached to the outer surface of the nasal tube, the nasal tube can be fixed and clamped. When the second limiting plate 29 moves to the right, the nasal tube can be easily removed. The cooperation of the screw 23, the first limiting plate 25, and the second limiting plate 29 facilitates the fixing of nasal tubes of different diameters.
[0032] In this embodiment, the strapping device 5 includes two mounting straps 51. Each mounting strap 51 has a magnetic snap 52 at its upper end away from the fixing piece 1, a magnetic seat 53 at its upper end near the fixing piece 1, an elastic band 54 at its upper end away from the fixing piece 1, and a fixing strap 55 at its lower end away from the mounting strap 51. The upper end of the left fixing strap 55 and the lower end of the right fixing strap 55 are both provided with Velcro 56. The two fixing straps 55 are movably bonded together by the Velcro 56.
[0033] Through the above scheme: the fixing strap 55 is tightly connected with the mounting strap 51 and the elastic strap 54 to form a complete closed loop structure. The magnetic buckle 52 and magnetic seat 53 on the mounting strap 51 facilitate the installation and fixing of the two mounting straps 51. The elastic strap 54 enables the threading device 5 to adapt to different body parts. The two fixing straps 55 are used in conjunction with the Velcro 56 to achieve the final fixing and adjustment of the threading device 5.
[0034] It should be noted that this utility model is a nasotracheal intubation fixation device. During use, firstly, two fixing straps 55 are inserted into the two insertion holes 4 respectively, and then magnetically engaged by the magnetic buckle 52 and magnetic seat 53, fixing the two fixing straps 55 within the two insertion holes 4. This makes the insertion device 5 and the fixing piece 1 form a whole. In use, the fitting pad 7 is attached to the surface of the patient's skin. The fitting pad 7 is made of sponge to avoid skin damage caused by prolonged tight pressure. Then, the insertion device 5 is easily fixed by the cooperation of two Velcro straps 56. When fixing the nasal trachea, one end of the nasal trachea is inserted into the limiting seat 2. The nasal trachea is positioned between the first limiting plate 25 and the second limiting plate 29. By manually rotating the knob 24, the second limiting plate 29 can be moved left and right. With the cooperation of the four balance rods 27, the movement of the limiting plate 29 is more stable, avoiding the problem of the second limiting plate 29 tilting at an angle during movement. When the second limiting plate 29 moves to the left until the inner protective pad 26 is tightly attached to the outer surface of the nasal trachea, the nasal trachea can be fixed and clamped. When the second limiting plate 29 moves to the right, the nasal trachea can be easily removed. The screw 23, the first limiting plate 25 and the second limiting plate 29 can be used to fix nasal tracheas of different diameters.
