Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to a movable fixation device for endotracheal intubation. Background Technology
[0002] For patients with respiratory dysfunction, endotracheal intubation is necessary. Clinically, an endotracheal tube is usually inserted through the mouth to assist breathing. During endotracheal intubation, patients have voluntary and involuntary reflexes and often unconsciously bite the tube. Biting the tube can easily cause it to fold or deform, affecting airflow and even potentially leading to endotracheal tube occlusion and suffocation. Therefore, after successful endotracheal intubation, a bite block is usually placed between the patient's upper and lower incisors, and then the endotracheal tube is secured to the bite block using adhesive tape and a tether. This method of securing the tube is cumbersome and not very secure.
[0003] Current endotracheal tubes are generally fixed in one position and cannot be easily moved to the left or right. This means that the pressure of the endotracheal tube on the airway mucosa remains on one side, which can easily cause pressure injury to the airway mucosa. When the patient needs oral cleaning, the endotracheal tube needs to be moved to both sides of the mouth to facilitate oral cleaning by medical staff. This requires first removing the adhesive tape and fixing ropes, completing the cleaning, and then re-fixing with adhesive tape and fixing ropes, increasing the workload of medical staff. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a movable fixing device for endotracheal tubes, which can fix the endotracheal tubes, prevent slippage, and facilitate the movement of the endotracheal tubes to both sides of the oral cavity.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A movable fixation device for endotracheal tubes mainly includes a fixation plate, a clamping plate, and a fixation structure for fixing the endotracheal tube. The fixation structure is movably clamped between the fixation plate and the clamping plate. Both the fixation plate and the clamping plate are arc-shaped plate structures. Fixing straps are installed at both ends of the length direction of the fixation plate. A first window for exposing the oral cavity is opened on the fixation plate. The length direction of the first window is parallel to the length direction of the fixation plate. A connecting block is installed on the outer surface of the fixation plate. The connecting block is installed on the first side of the length direction of the first window. A connecting hole is opened on the connecting block. The axis of the connecting hole is parallel to the width direction of the fixation plate. The clamping plate is rotatably connected in the connecting hole of the connecting block. A protrusion is installed at the first end of the clamping plate along its length, and a rotating shaft is installed on the protrusion. The axis of the rotating shaft is parallel to the width direction of the clamping plate, and the rotating shaft is rotatably connected in a connecting hole. A connecting rod is vertically installed on the second side of the outer plate of the fixing plate along the length of the first window. A pressure plate is protruding at the second end of the clamping plate along its length, and a notch is opened on the pressure plate. When the clamping plate rotates towards the fixing plate, the connecting rod is engaged in the notch. A fixing stud is threaded onto the connecting rod. When the lower end face of the fixing stud abuts against the upper end face of the pressure plate, the lower end face of the pressure plate abuts against the outer plate surface of the fixing plate. A second window is opened on the clamping plate, and the second window is directly opposite the first window.
[0007] The fixing structure mainly includes a fixing tube and two fixing wings. The diameter of the fixing tube is smaller than the width of the first window and the second window. The endotracheal tube is inserted into the fixing tube. The two fixing wings are symmetrically installed on the outer wall of the fixing tube. The fixing wings divide the fixing tube into a first part and a second part. The first part is placed inside the oral cavity, and the second part is placed outside the clamp. A limiting hole is opened on the second part, and a limiting rod is threaded into the limiting hole. The lower end of the limiting rod abuts against the endotracheal tube. The end face of the fixing wing is parallel to the end face of the fixing tube. Both fixing wings are clamped between the fixing plate and the clamp. The two fixing wings are located on both sides of the width direction of the first window.
[0008] Furthermore, a buffer pad is installed on the inner surface of the fixing plate.
[0009] Furthermore, the inner surface of the clamping plate is provided with a silicone layer.
[0010] Furthermore, a handle for rotation is installed at the upper end of the fixing stud.
[0011] Furthermore, a handle for rotation is installed at the upper end of the limiting rod.
[0012] Furthermore, the lower end of the limiting rod is rotatably connected to an arc-shaped clamping block, the arc-shaped opening of which faces the side of the endotracheal tube.
[0013] Furthermore, the fixed wing is an arc-shaped plate, and the inner plate surface of the fixed wing can be fitted with the outer plate surface of the fixed plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention uses a fixing strap to secure a fixing plate to the patient's face. The endotracheal tube, fixed within the fixing structure, is placed inside the patient's mouth. The fixing structure is then held in place by the fixing plate and clamps, preventing it from moving outwards or inwards. When it is necessary to move the endotracheal tube to the sides of the mouth, the fixing studs are loosened, releasing the clamps and fixing plate from the fixing structure, allowing the endotracheal tube to move to the sides of the mouth. Once in the desired position, the fixing studs are tightened again. Attached Figure Description

[0027] A specific embodiment, as shown in the figure, represents a preferred embodiment of this utility model. A movable fixing device for an endotracheal tube mainly includes a fixing plate 4, a clamping plate 1, and a fixing structure for fixing the endotracheal tube. The fixing structure is movably clamped between the fixing plate 4 and the clamping plate 1. Both the fixing plate 4 and the clamping plate 1 are arc-shaped plate structures. Fixing straps 5 are installed at both ends of the length direction of the fixing plate 4. A first window 16 for exposing the oral cavity is opened on the fixing plate 4. The length direction of the first window 16 is parallel to the length direction of the fixing plate 4. A connecting block 11 is installed on the outer surface of the fixing plate 4. The connecting block 11 is installed on the first side of the length direction of the first window 16. A connecting hole is opened on the connecting block 11. The axis of the connecting hole is parallel to the width direction of the fixing plate 4. The clamping plate 1 is rotatably connected within the connecting hole of the connecting block 11. A protrusion 12 is installed at the first end of the clamping plate 1 along its length. A rotating shaft is installed on the protrusion 12. The axis of the rotating shaft is parallel to the width direction of the clamping plate 1. The rotating shaft is rotatably connected in a connecting hole. A connecting rod is vertically installed on the second side of the outer plate of the fixing plate 4 along the length of the first window 16. A pressure plate 7 protrudes from the second end of the clamping plate 1 along its length. A notch is opened on the pressure plate 7. When the clamping plate rotates towards the fixing plate 4, the connecting rod is engaged in the notch. A fixing stud 8 is threaded onto the connecting rod. When the lower end face of the fixing stud 8 abuts against the upper end face of the pressure plate 7, the lower end face of the pressure plate 7 abuts against the outer plate of the fixing plate 4. A second window 15 is opened on the clamping plate 1. The second window 15 and the first window 16 are directly opposite each other.
[0028] The fixing structure mainly includes a fixing tube 9 and two fixing wings 17. The diameter of the fixing tube 9 is smaller than the width of the first window 16 and the second window 15. The endotracheal tube is inserted into the fixing tube 9. The two fixing wings 17 are symmetrically installed on the outer wall of the fixing tube 9. The fixing wings 17 divide the fixing tube 9 into a first part and a second part. The first part is placed inside the oral cavity, and the second part is placed on the outside of the clamping plate 1. A limiting hole is opened on the second part, and a limiting rod 3 is threaded into the limiting hole. The lower end of the limiting rod 3 abuts against the endotracheal tube. The end face of the fixing wing 17 is parallel to the end face of the fixing tube 9. Both fixing wings 17 are clamped between the fixing plate 4 and the clamping plate 1. The two fixing wings 17 are located on both sides of the width direction of the first window 16.
[0029] In the specific implementation of this utility model, firstly, the fixing plate 4 is fixed to the patient's face using the fixing strap 5, so that the first window 16 on the fixing plate 4 can face the patient's lips; the endotracheal tube is inserted into the fixing tube 9 of the fixing structure, and the first part of the fixing tube 9 is passed through the first window 16 and enters the patient's oral cavity. The patient's teeth or gums bite on the first part, and the first part of the fixing tube 9 plays a protective role for the endotracheal tube, preventing the endotracheal tube from being compressed and affecting the patient's breathing. After the fixation tube 9 is inserted into the oral cavity, the position of the fixing wings 17 on the fixation tube 9 is adjusted so that the two fixing wings 17 are located on both sides of the width direction of the first window 16. The fixing stud 8 on the connecting rod is removed, and the clamping plate 1 is rotated to allow the second part of the fixation tube 9 to pass through the second window 15, so that the notch on the pressure plate 7 on the clamping plate 1 is engaged with the connecting rod of the fixing plate 4. Then, the fixing stud 8 is threadedly connected to the connecting rod. By continuously pressing down on the upper end face of the pressure plate 7, the clamping plate is pressed against the outer plate surface of the fixing plate 4 by the fixing stud 8, thereby fixing the position of the clamping plate 1 and clamping the fixing wings 17 between the clamping plate 1 and the fixing plate 4. Furthermore, the clamping plate 1 is an elastic plate. The deformation of the clamping plate 1 generates elastic force, which better clamps and fixes the fixing wings 17, thereby fixing the fixation tube 9 with the fixing wings 17 and preventing the fixation tube 9 from detaching from the oral cavity. After the fixation tube 9 is secured, rotate the limiting rod 3, causing its lower end to press down and abut against the side wall of the endotracheal tube, thus fixing the endotracheal tube inside the fixation tube 9. Therefore, this invention can be used to secure the tube well inside the oral cavity. When it is necessary to move the endotracheal tube to the left or right sides of the oral cavity, loosen the fixing stud 8 so that the clamp 1 and the fixing plate 4 no longer clamp the fixing wing 17. Medical staff can then hold the second part of the fixation tube 9 and move the fixation tube 9 and the endotracheal tube inside it to the sides of the oral cavity. Because the fixing wing 17 is still between the clamp 1 and the fixing plate 4, the fixation structure will not move in or out of the patient's oral cavity, which is relatively safe. After the fixation structure is moved to the sides of the oral cavity, medical staff can insert cleaning tools into the patient's oral cavity through the second window 15 and the first window 16, clean one side of the oral cavity first, and then move the fixation structure to the other side to clean that side of the oral cavity. This operation facilitates the cleaning of the patient's oral cavity by medical staff and also facilitates the movement of the endotracheal tube to prevent mucosal damage. When it is necessary to fix the endotracheal tube, move the endotracheal tube to the required position and tighten the fixing stud 8 again to fix the endotracheal tube in the fixing structure. It is very convenient to use and operate.
[0030] Furthermore, a buffer pad 13 is installed on the inner surface of the fixing plate 4. When the inner surface of the fixing plate 4 is in contact with the patient's skin, the buffer pad 13 plays a buffering role, preventing the fixing plate 4 from pressing directly on the patient's face and improving comfort.
[0031] Furthermore, the inner surface of the clamping plate 1 is provided with a silicone layer, which can not only increase friction and reduce the movement of the fixed wing 17, but also deform the silicone layer when clamping the fixed wing 17, generating elasticity, which can better fix the fixed wing 17.
[0032] Furthermore, a handle for rotation is installed at the upper end of the fixing stud 8 to facilitate tightening or loosening of the fixing stud 8.
[0033] Furthermore, a handle for rotation is installed at the upper end of the limiting rod 3, which facilitates tightening or loosening the limiting rod 3.
[0034] Furthermore, the lower end of the limiting rod 3 is rotatably connected to an arc-shaped clamping block 10. The arc-shaped opening of the clamping block 10 faces the side of the endotracheal tube. By increasing the contact area with the endotracheal tube through the clamping block 10, damage to the endotracheal tube can be prevented when the limiting rod 3 is pressed down, and the endotracheal tube can be better fixed by the clamping block 10.
[0035] Furthermore, the fixed wing 17 is an arc-shaped plate, and the inner plate surface of the fixed wing 17 can be fitted with the outer plate surface of the fixed plate 4, increasing the contact area between the fixed wing 17 and the fixed plate 4 and the clamping plate 1, so that the fixed wing 17 can be better fixed.
[0036] Furthermore, a protective sleeve 6 is detachably installed on the fixing strap 5 to provide protection and reduce the risk of the fixing strap 5 strangulating the patient. The protective sleeve 6 is fitted onto the fixing strap 5 and can be removed for cleaning.
[0037] Furthermore, the first part of the fixing tube 9 is provided with a concave occlusal area 14, and the occlusal area 14 is provided with a buffer pad 13, which increases the contact area of occlusion, and the buffer pad 13 can improve the comfort of the patient when using it.
[0038] Furthermore, the second part of the fixation tube 9 is surrounded by a sleeve block 2, and the limiting hole is opened on the sleeve block 2. Because the fixation tube 9 needs to be inserted into the patient's mouth, its diameter cannot be too large, and therefore, its wall thickness cannot be too thick. Without increasing the diameter of the fixation tube 9, the sleeve block 2 can increase the wall thickness of the second part of the fixation tube 9, making the hole depth of the limiting hole deeper, and the threaded connection between the limiting rod 3 and the limiting hole more stable, thereby facilitating the use of the limiting rod 3 to fix the endotracheal tube. Because the sleeve block 2 increases the diameter of the fixation tube 9, if the diameter of the sleeve block 2 is larger than the second window 15, then further, the width of the fixing wing 17 is smaller than the width of the second window 15. By rotating the fixing wing 17, so that the fixing wing 17 passes laterally through the clamping plate 1 from the second window 15, the first part of the fixation tube 9 can enter the first window 16, while the sleeve block 2 remains outside the clamping plate 1.
[0039] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
