Description

Technical Field

[0001] This application relates to the field of medical technologies, and particularly to a tracheal intubation fixation device. Background Art

[0002] A tracheal intubation is a medical device used to insert into a patient's trachea to maintain ventilation. It is usually made of soft materials such as polyvinyl chloride (PVC) or silicone. The tracheal intubation has a relatively small outer diameter and inner diameter and can be inserted into the trachea through the patient's oral cavity or nasal cavity for tracheal intubation and mechanical ventilation.

[0003] Currently, the tape fixation method is commonly used to fix tracheal intubations, but the tape is prone to falling off, causing the tracheal intubation to move. To improve the fixation, there is a product of a tracheal intubation fixator on the market now. This product belongs to the mask type, that is, there is a fixing plate structure to cover the patient's lips. For example, a disclosed tracheal intubation fixator (Application No.: 2023223620198) includes a fixing plate in contact with the lips, and a structure for fixing the tracheal intubation is provided in the middle of the fixing plate. This mask type covers the lips and cannot observe the conditions of the lips and oral cavity. At the same time, it will also compress the patient's lips, which is likely to cause pressure injuries after a long time. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a tracheal intubation fixation device that can prevent compression on the lips when fixing the tracheal intubation.

[0019] Aiming at the defect in the prior art that it is easy to cause compressive injury to the patient's lips. After careful analysis by the inventor, it is found that the main reason for the above problem lies in the existing tracheal intubation fixator. It has a fixing plate, which is used to fix the position of the tracheal intubation in the patient's oral cavity. In order to prevent the trachea from moving, the fixing plate usually fits with the lips. Especially when the patient lies in bed, the fixing plate presses down on the lips, making it easier to cause compressive injury to the lips. In addition, in order to prevent the fixing plate from moving, on both sides of the fixing plate, ear straps similar to those used in masks are tied. The ear straps pull the fixing plate, making the fixing plate contact the lips more tightly, further aggravating the compressive injury. Secondly, the ear straps are tied on the sensitive skin of the back of the ear, which will also cause swelling and redness of the back of the ear after a long time. Based on the above analysis, the inventor has made a structural improvement to the tracheal intubation fixator.

[0020] As Figures 1-4 shown, in an embodiment of the tracheal intubation fixing device of the present application, the device includes a head fixing component, a connecting component, and a tracheal intubation fixing component 5; the head fixing component includes a cap body 1, and a hollow locking member is provided at the front end of the cap body 1. The connecting component includes an adjusting plate 4, and the adjusting plate 4 is arranged in the locking member. The bottom of the adjusting plate 4 is connected to the tracheal intubation fixing component 5. The tracheal intubation fixing component 5 includes a tube body 51. A vertical groove 56 is opened on the side wall of the tube body 51, a wedge bar 53 is arranged in the vertical groove 56, and an inclined groove 52 inclined towards the middle of the tube body 51 is opened at the left end of the vertical groove 56.

[0021] The cap body 1 is a conventional hat with a hollow top. The purpose of the hollow is to reduce the contact area between the cap body 1 and the patient's head and improve air permeability. A soft pad can be pasted on the inner wall of the cap body 1, which can improve the comfort of the patient when wearing.

[0022] The function of the locking member is to lock the adjusting plate 4. The locking member includes a rectangular hoop 2 made of plastic or metal. The rear end of the hoop 2 and the front end of the cap body 1 are preferably adhesively connected with glue. A threaded hole is opened at the front end of the hoop 2, and a bolt 3 is arranged in the threaded hole; the adjusting plate 4 is arranged in the hoop 2. When the bolt 3 is tightened, the screw presses against the front end face of the adjusting plate 4, and the adjusting plate 4 is compacted and cannot move. When the bolt 3 is loosened, the adjusting plate 4 can move up and down.

[0023] The side view of the adjusting plate 4 has a curvature and has a certain resilience. The curvature is provided to prevent the adjusting plate 4 from pressing too hard on the patient's nose.

[0024] A fixing ring 41 is connected to the bottom of the adjusting plate 4, and the endotracheal tube fixing assembly 5 is installed in the fixing ring 41 by interference fit or glue adhesion.

[0025] There are at least two vertical grooves 56, which can ensure that the force applied when the wedge 53 presses the endotracheal tube 6 is relatively balanced. In this embodiment, there are four vertical grooves 56, and they are evenly distributed circumferentially on the side wall of the endotracheal tube fixing assembly 5.

[0026] A limiting groove 561 is provided on the side surface of the vertical groove 56, and a protrusion 541 is provided on the side surface of the wedge 53. The protrusion 541 is arranged in the limiting groove 561 of the vertical groove 56, so that the wedge 53 will not come out of the vertical groove 56.

[0027] A pressing flange 54 is provided at the right end of the wedge 53. In this embodiment, the pressing flange 54 is circular. The pressing flange 54 connects the right ends of the four wedges 53 together. By pressing the pressing flange 54, the four wedges 53 can move uniformly.

[0028] The left end of the wedge 53 is an arc surface.

[0029] In this embodiment, the vertical groove 56 is opened on the outer wall of the left side of the pipe body 51, and the opening faces to the right, which is convenient for installing the wedge 53 in the vertical groove 56. To prevent the wedge 53 from slipping out horizontally to the right, threads are provided on the outer wall of the right end of the pipe body 51, and a nut 55 is screwed on the threads. When the pressing flange 54 moves to the right, it will contact the nut 55, and at this time, the pressing flange 54 cannot move further to the right, preventing it from slipping out.

[0030] All components of this device can be made of medical plastic materials.

[0031] When in use, first put the cap body 1 of the fixing assembly on the patient's head, then insert the adjusting plate 4 from bottom to top into the hoop 2 of the locking member, adjust the endotracheal tube fixing assembly 5 to be between the patient's upper and lower lips, and then tighten the bolt 3 to press the fixing plate. The final effect diagram is as shown in Figure 1 and Figure 2 shown, and then sleeved the endotracheal tube fixing assembly 5 on the endotracheal tube 6. As shown in Figure 3As shown, the tracheal intubation 6 has not been fixed in this state. Hook the left end face of the fixing ring 41 with the index finger, press the right end face of the pressing flange 54 with the thumb, apply force, and the wedge 53 moves to the left. The left end of the wedge 53 will contact the groove surface of the inclined groove 52. The wedge 53 continues to move to the left. The wedge 53 will be squeezed by the inclined groove 52 and continue to move to the left in the space between the pipe body 51 and the tracheal intubation 6. At the same time, the wedge 53 is squeezed by the groove surface of the inclined groove 52 and will also swing and move towards the middle of the pipe body 51. The inner wall of the wedge 53 squeezes the tracheal intubation 6 along the trend, generating a certain frictional force, thereby fixing the tracheal intubation 6. When it is necessary to remove the tracheal intubation 6, pull the tracheal intubation 6 to the right. There is a frictional force between the surface of the tracheal intubation 6 and the wedge 53, driving the wedge 53 to move to the right. The wedge 53 returns to the vertical groove 56 of the pipe body 51, and the tracheal intubation 6 is not squeezed and limited, so it can be taken out.

[0032] The baffle covering the lips is omitted, which can prevent compressive injuries to the patient's lips; without the baffle covering the lips, the lips are exposed, and medical staff can also directly observe the situation of the lips and the oral cavity.

[0033] It should be understood that all the above embodiments are exemplary rather than restrictive. Under the concept of this application, those skilled in the art make various modifications or deformations to the specific embodiments described above, and they should all be within the protection scope of this application.
