Abstract
Description
Technical Field
[0001] This invention is a tracheal tube fixation device for neonatal care, belonging to the field of neonatal care technology. Background Technology
[0002] A neonatal endotracheal tube is a medical device specifically designed for newborns, typically used for respiratory support. Newborns have fragile respiratory systems, and endotracheal tubes help maintain airway patency, providing artificial respiration or airway management. Common applications include neonatal asphyxia, premature infants, respiratory failure, or situations requiring mechanical ventilation. Because newborns' physiological functions are not fully developed, and their airways are narrow and delicate, endotracheal tube ventilation is a common nursing method for critically ill newborns. During resuscitation, to prevent movement of the endotracheal tube, it needs to be secured. Existing methods generally include the bite block method and the tape method. The bite block method involves placing a bite block between the patient's upper and lower incisors, which is unsuitable for newborns who have not yet grown teeth. The tape method involves directly attaching adhesive tape to the skin to secure the endotracheal tube, relying heavily on tape or simple clamps. This method is prone to displacement or dislodgement due to the newborn's unconscious twisting, potentially causing airway injury. Furthermore, newborns' skin is delicate and lacks flexibility, making it difficult to precisely adapt to different newborn positions (such as supine or lateral) and the required depth of tube insertion.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1-7 The present invention provides a technical solution for a tracheal tube fixing device for neonatal care, including a base plate 1 and a fixing mechanism for fixing the tracheal tube; The top of the base plate 1 is provided with a slidingly connected U-shaped frame 2. The top of the U-shaped frame 2 is provided with a horizontally arranged crossbeam 3. The crossbeam 3 is provided with a transverse movement mechanism for transverse movement. One side of the transverse movement mechanism is provided with a vertically arranged side plate 4. One side of the side plate 4 is provided with a horizontally arranged mounting ring 5. The bottom of the mounting ring 5 is provided with an angle adjustment mechanism for adjusting the angle of the fixing mechanism. The side plate 4 is provided with a vertical movement mechanism for raising and lowering the mounting ring 5; The top of the base plate 1 is provided with a support 6 to cover the U-shaped frame 2; The angle adjustment mechanism includes three sets of support blocks 7 evenly arranged around the bottom of the mounting ring 5.

Both the connecting rod 8 and the connecting rod 9 are arc-shaped structures. A motor 10 for driving the connecting rod 8 to rotate is provided on the support block 7.
[0020] Please see Figure 1-7The fixing mechanism includes a circular shell 11 movably connected to the bottom of the connecting rod 9. A through hole 12 for the endotracheal tube to pass through is provided in the center of the circular shell 11. Several fixing plates 13 extending into the through hole 12 are arranged around the circular shell 11. The fixing plates 13 are petal-shaped and movably connected to the circular shell 11 via a rotating shaft 14. An external toothed ring 15 is rotatably connected inside the circular shell 11. An arc-shaped rod 16, movably connected to the top of the external toothed ring 15 and movably connected to the corner of the fixing plate 13, is movably connected to the external toothed ring 15 and the fixing plate 13 via a pin 17. The motor 10 on the support block 7 is started, driving the arc-shaped connecting rod 8 to rotate. This, through the connecting rod 9, causes the circular shell 11 to rotate around the bottom of the mounting ring 5, adjusting the tube clamping angle to ensure the tube remains coaxial with the airway and avoids compressing the airway.
[0021] Please see Figure 1-7 The bottom of the circular shell 11 is surrounded by several sliding shafts 18 that movably pass through the external gear ring 15. The external gear ring 15 has stroke holes 19 for the sliding shafts 18 to move. A driven gear 20 that meshes with the external gear ring 15 is rotatably connected inside the circular shell 11. A transmission gear 21 that meshes with the driven gear 20 is provided on one side of the driven gear 20. The transmission gear 21 is movably connected to the circular shell 11 through a shaft 22. A worm gear 23 is sleeved on the shaft 22. A worm 24 that meshes with the worm gear 23 is provided on one side of the worm gear 23. One end of the worm 24 extends to the outside of the circular shell 11 and is provided with a rotating wheel 25. The worm 24 is movably connected to the circular shell 11 through a bearing. There are five sets of fixed plates 13, and their outer walls are in close contact with each other.
[0022] Please see Figure 1-7 The transverse movement mechanism includes guide posts 26 symmetrically arranged at the top of the U-shaped frame 2, with a lead screw 36 between the two sets of guide posts 26. A moving block 27 is threaded onto the lead screw 36 and slidably connected to the guide post 26. A servo motor 28 for driving the lead screw 36 is provided on one side of the U-shaped frame 2.
[0023] Please see Figure 1-7The vertical movement mechanism includes guide posts 29 arranged vertically symmetrically on one side of the side plate 4. A lead screw 30 is provided between the two sets of guide posts 29. Both ends of the two sets of guide posts 29 and the lead screw 30 are movably connected to the brackets 31 connected to the side plate 4. The two sets of guide posts 29 and the lead screw 30 vertically penetrate the moving block 27. The moving block 27 has guide holes and threaded holes that match the guide posts 29 and the lead screw 30. The upper bracket 31 is provided with a servo motor 32 for driving the lead screw 30. The top of the base plate 1 and below the support 6 are symmetrically provided with guide posts 33 that movably penetrate the U-shaped frame 2. A lead screw 34 threaded through the U-shaped frame 2 is provided between the two sets of guide posts 33. The base plate 1 is provided with a servo motor 35 for driving the lead screw 34. Start servo motor 28 to drive lead screw 36 to rotate, and move block 27 slides laterally along guide post 26 to achieve precise lateral positioning of side plate 4 and fixing mechanism. Then start servo motor 32 to drive lead screw 30 to rotate, and move block 27 slides vertically along guide post 29, driving installation ring 5 and fixing mechanism to rise and fall to match the tube insertion height. According to the newborn's position requirements, start servo motor 35 to drive lead screw 34 to rotate, so that U-shaped frame 2 slides laterally along guide post 33, driving crossbeam 3 and subsequent components to adjust the lateral position as a whole to adapt to the newborn bed and airway position.
[0024] In use, servo motor 35 drives screw 34 to rotate, causing U-shaped frame 2 to slide laterally along guide post 33, adjusting the horizontal position of crossbeam 3 and subsequent components to match the neonatal bed and airway position. Then, servo motor 1 drives screw 36 to rotate, causing moving block 27 to slide laterally along guide post 26, achieving precise lateral positioning of side plate 4 and fixing mechanism. Servo motor 2 drives screw 20 to rotate, causing moving block 27 to slide vertically along guide post 29, raising and lowering mounting ring 5 and fixing mechanism to match the tube insertion height. Based on the neonatal position requirements, motor 10 on support block 7 drives arc-shaped connecting rod 8 to rotate, which in turn drives round shell 11 to rotate around the bottom of mounting ring 5 via connecting rod 9, adjusting the tube clamping angle to ensure the tube and airway remain coaxial, avoiding airway compression and allowing air to pass through. The conduit passes through the through hole 12 in the middle of the circular shell 11. Rotating the rotating wheel 25 drives the worm gear 24 to rotate. The worm gear 24 meshes with and drives the worm wheel 23 and the shaft 22 to rotate. The transmission gear 21 on the shaft 22 meshes with the driven gear 20, thereby driving the external gear ring 15 to rotate along the sliding shaft 18. The external gear ring 15 pulls the fixing plate 13 around the rotating shaft 14 through the arc rod 16 to synchronously close, thereby clamping and fixing the conduit. Rotating the rotating wheel 25 in the opposite direction causes the fixing plate 13 to synchronously open, thereby releasing the conduit. When the position of the conduit needs to be adjusted during the nursing process, the corresponding servo motor 1 28, servo motor 2 32 and servo motor 35 or motor 10 can be started individually to achieve independent horizontal, vertical or angular adjustment without disassembling the fixing mechanism, ensuring the stability of the conduit position during the adjustment process.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
