Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a movable endotracheal tube fixation device. Background Technology

[0002] As is well known, endotracheal intubation is a device used for breathing, anesthesia, and emergency care to maintain a patient's airway patency and ensure the proper delivery of oxygen and anesthetic drugs. It is a tubular device that connects the airway to a ventilator or anesthesia machine by being inserted into the patient's trachea for artificial ventilation or anesthesia. Currently, in clinical practice, after endotracheal intubation, a bite block is typically placed to protect the trachea and prevent the patient from biting it. Then, tape is used to secure the bite block and trachea to the patient's face.

[0003] Currently, the traditional adhesive tape method for securing endotracheal tubes presents significant safety risks. When the patient moves their mouth, rotates their head, or breathes, the tape can easily stretch and detach, causing the endotracheal tube to shift or even dislodge, posing a serious threat to the patient's life. Secondly, the tape method is inconvenient to adjust, as it can only be fixed in one place, hindering oral care and examination. During intubation, the patient's oral mucosa is easily damaged, requiring regular oral care. The tape method restricts the caregiver's operation, increasing the difficulty of oral care and thus affecting the effectiveness of the endotracheal tube securing device. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a movable endotracheal tube fixation device. The main purpose is to solve the problem that when a patient's mouth moves, head rotates, or breathes, the tape is easily stretched and detached, leading to endotracheal tube displacement, and in severe cases, even tube dislodgement, posing a serious threat to the patient's life. Secondly, the tape fixation method is inconvenient to adjust, as it can only be fixed in one place, which is not conducive to oral care and examination.

[0024] like Figure 1 and Figure 2As shown, a groove 18 is provided on the top of the face fixation device body 1. The groove 18 can fit the protrusion of the nose, improving the overall comfort of the fixation device.

[0025] like Figure 1 and Figure 2 As shown, the first fixing strap assembly includes a first elastic strip 1901 and a second elastic strip 1903, both of which are engaged with the first mounting hole 2. One end of the first elastic strip 1901 is engaged with a through loop 1902, and the second elastic strip 1903 passes through the through loop 1902. The second elastic strip 1903 has a hook-and-loop fastener layer 1904 and a loop-and-loop fastener layer 1905 on both sides, respectively, and the hook-and-loop fastener layer 1904 and the loop-and-loop fastener layer 1905 are bonded together. By setting the first elastic strip 1901 and the second elastic strip 1903, and with both strips engaging with the first mounting hole 2... The first mounting hole 2 of the fixation device is engaged. One end of the first elastic strip 1901 has a loop 1902 to pass through the second elastic strip 1903. On both sides of the second elastic strip 1903, a hook-and-loop fastener 1904 and a loop-and-loop fastener 1905 are respectively arranged to hook together. This design can effectively prevent the endotracheal tube from shifting or falling off during the patient's oral movement, head rotation or breathing movements. It can also adjust the tightness of the fixation device, improving the patient's installation comfort. Multiple ventilation holes are opened on one side of the face fixation device body 1 to improve the overall ventilation of the device, thereby improving its comfort of use.

[0026] The working principle of this embodiment is as follows: When endotracheal intubation through the mouth is required, it is first fixed by the first fixing strap assembly. The second elastic strip 1903 is passed through the loop 1902 on the first elastic strip 1901. The facial fixator body 1 is fixed to the face by the hook and loop fasteners 1904 and fuzzy fasteners 1905. Then, the endotracheal tube is inserted into the human trachea through the first tube fixator 10. The silicone pad 1001 and anti-slip protrusion 1002 inside the first tube fixator 10 can prevent the endotracheal tube from falling out. The facial fixator body 1 is 3D printed to fit the contour of the patient's head and face. The arc-shaped double guide rod 4, designed according to the curvature of the patient's lips, is printed with rigid material and is used for the movement of the first tube fixator 10 to ensure that the endotracheal tube will not shift or fall out during the movement. It can achieve the effect of oral care and examination of intubated patients through the oral placement hole 3 without disassembling the facial fixator body 1, and can observe the color of the patient's lips and the surrounding skin in real time. When adjusting the first catheter fixator 10, the first step is to turn the rotary knob 12, which allows the slider 9 to slide up and down. The rotating shaft 13 and the limiting plate 15 on the slider 9 are rotatably connected to the rotating groove 14 on the first catheter fixator 10, allowing for angle adjustment. When tightening is required, the rotary knob 12 is turned clockwise, and the threaded rod 11 begins to stand up, clamping the slider 9 to prevent it from sliding up and down. Then, under the action of the threaded rod 11, the push rod 16 contacts the groove 18, pushing the first catheter fixator 10 to one side. Under the action of the limiting plate 15, the first catheter fixator 10 is tightened to prevent the angle of the first catheter fixator 10 from changing, thus improving the stability of the first catheter fixator 10. Furthermore, the pressure block 503 on the arc plate 502 of the first sliding sleeve 5 can pass through the card hole 501 and contact the guide rod 4 to prevent it from sliding freely, thus improving the stability of the fixing device. Example

[0027] Reference Figures 6-7 A movable endotracheal tube fixation device is disclosed.

An observation hole 22 is provided on one side of the neck fixation body 20, and a second tube fixator 23 is integrally formed on the inner wall of the observation hole 22. By using the second fixation strap assembly built into the second mounting holes 21 on both sides of the neck fixation body 20, the position of the endotracheal tube can be flexibly adjusted. At the same time, the second tube fixator 23 integrally formed on the inner wall of the observation hole 22 on one side of the neck fixation body 20 can ensure that the endotracheal tube is firmly fixed, prevent the tube from shifting or falling off due to patient movement, and facilitate the disinfection and observation of the neck wound.

[0028] The working principle of this embodiment is as follows: When using this device on a patient with a tracheotomy in the neck, the trachea is first fixed by the second fixation strap assembly. The second fixation strap assembly has the same structure as the first fixation strap assembly, achieving overall fixation. Then, the trachea is inserted into the second catheter fixator 23. The wound can be observed and disinfected through the observation hole 22. The neck fixator body 20 is 3D printed to fit the contour of the patient's neck. It is printed in one piece using medical-grade silicone-like soft and hard resin, creating a soft and skin-fitting second catheter fixator 23. This ensures that the fixation device fits snugly and firmly while facilitating the use of different tube diameters.
