Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, and particularly relates to an oral tracheal intubation fixation device. Background Art
[0002] In the medical field, tracheal intubation technology is a crucial treatment method, especially when dealing with critically ill patients. It involves inserting a special catheter through the patient's glottis into the trachea to ensure that the patient can breathe normally, receive necessary ventilation and oxygen supply, and at the same time facilitate airway suction and prevent aspiration. However, although tracheal intubation technology has provided great help to critically ill patients, how to ensure the stability and safety of tracheal intubation fixation has always been a challenge for medical staff.
[0003] Currently, in clinical practice, the tracheal intubation is usually placed on the side of the bite block and fixed with adhesive tape. Specifically, first, a short adhesive tape is used for preliminary fixation, and then two long adhesive tapes or long strips of gauze are used for cross-binding reinforcement. Although this fixation method ensures the stability of the tracheal intubation to a certain extent, it also has obvious disadvantages. First, during each oral care, medical staff need to tear off the old adhesive tape and paste a new one, which not only increases the operation difficulty and time cost, but also may bring additional pain and discomfort to the patient. Second, the patient's saliva is likely to wet the adhesive tape, causing the adhesive tape to lose its stickiness, thus increasing the risk of tube dislodgment. At the same time, long-term fixation with gauze binding is likely to cause cutting injuries to the patient's mouth corners. If the patient's consciousness can remain awake during the day, they will still rely on their physiological instinct to spit out the bite block and tracheal intubation, etc. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide an oral tracheal intubation fixation device to solve the technical problems mentioned in the above background art.
[0005] The utility model provides an oral tracheal intubation fixation device, which includes two arc-shaped clamping plates. A semi-closed bayonet for cooperating with the tracheal intubation is provided in the middle of each of the two arc-shaped clamping plates. A male thread sleeve is provided on the end face of one of the arc-shaped clamping plates along the edge of the semi-closed bayonet, and a female thread sleeve is provided on the end face of the other arc-shaped clamping plate along the edge of the semi-closed bayonet. The male thread sleeve is used for threadedly cooperating with the female thread sleeve to lock the two arc-shaped clamping plates on the outer wall of the tracheal intubation.
[0006] Buckles are provided on opposite sides of at least one of the arc-shaped clamping plates, and the buckles are used for threading a binding strap.
[0007] Furthermore, for the oral tracheal intubation fixation device, the semi-closed bayonet is a semi-closed round hole.
[0008] Furthermore, for the oral endotracheal tube fixation device, the central angle of the semi-closed round hole is 200° to 270°.
[0009] Furthermore, for the oral endotracheal tube fixation device, an elastic shrinkage sleeve is provided on the upper end surface of the male threaded sleeve, and an abutting structure for cooperating with the elastic shrinkage sleeve is provided on the inner wall of the female threaded sleeve. The abutting structure is used to squeeze the elastic shrinkage sleeve so that the elastic shrinkage sleeve shrinks inward to lock the outer wall of the endotracheal tube.
[0010] Furthermore, for the oral endotracheal tube fixation device, a first inclined surface inclined inward is provided on the outer wall of the elastic shrinkage sleeve, the abutting structure is an annular step arranged along the inner wall of the female threaded sleeve, and a second inclined surface inclined outward is provided on the inner wall of the annular step.
[0011] Furthermore, for the oral endotracheal tube fixation device, an inner folding groove is provided at the connection between the elastic shrinkage sleeve and the male threaded sleeve.
[0012] Furthermore, for the oral endotracheal tube fixation device, a clamping strip is provided on the inner wall of the elastic shrinkage sleeve.
[0013] Furthermore, for the oral endotracheal tube fixation device, a flexible gasket is provided on the end surface of at least one of the arc-shaped clamping plates.
[0014] Furthermore, for the oral endotracheal tube fixation device, an external thread is provided on the outer wall of the male threaded sleeve, and an internal thread is provided on the inner wall of the female threaded sleeve. The external thread cooperates with the internal thread to realize the fitting and locking between the male threaded sleeve and the female threaded sleeve.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. By the cooperation of the male threaded sleeve and the female threaded sleeve, combined with the semi-closed bayonet in the middle of the arc-shaped clamping plate, it can be tightly locked on the outer wall of the endotracheal tube. Then, the binding band can be fixed on the neck or head of the patient. Compared with the method of fixing the endotracheal tube with adhesive tape in the existing scheme, the operation is simpler and more convenient. And during the subsequent oral care process, only need to loosen the binding band to adjust the endotracheal tube, which will not cause additional discomfort to the patient.
[0017] 2. The arc-shaped clamping plate can be reused after disinfection. Compared with the disposable adhesive tape, it can effectively reduce the material cost and contribute to the sustainable development of the medical industry. Description of the Drawings

[0026] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0029] Please refer to Figures 1 to 5, the orotracheal intubation fixation device in the present utility model includes two arc-shaped clamping plates 10. Semi-closed clamping openings 11 for cooperating with the tracheal intubation 100 are provided in the middle of both arc-shaped clamping plates 10. A male thread sleeve 21 is provided along the edge of the semi-closed clamping opening 11 on the end face of one of the arc-shaped clamping plates 10, and a female thread sleeve 22 is provided along the edge of the semi-closed clamping opening 11 on the end face of the other arc-shaped clamping plate 10. The male thread sleeve 21 is used for threaded cooperation with the female thread sleeve 22 so that the two arc-shaped clamping plates 10 are locked on the outer wall of the tracheal intubation 100;
[0030] Buckles 30 are provided on opposite sides of at least one of the arc-shaped clamping plates 10, and a strap (not shown in the figure) is threaded through the buckles 30.
[0031] Through the cooperation of the male thread sleeve 21 and the female thread sleeve 22, combined with the semi-closed clamping opening 11 in the middle of the arc-shaped clamping plate 10, it can be tightly locked on the outer wall of the tracheal intubation 100. Subsequently, the strap can be fixed to the patient's neck or head. Compared with the method of fixing the tracheal intubation 100 with adhesive tape in the existing solution, the operation is simpler and more convenient. And during the subsequent oral care process, the tracheal intubation 100 can be adjusted by simply loosening the strap, without causing additional discomfort to the patient. Secondly, the arc-shaped clamping plate 10 can be reused after disinfection. Compared with the disposable adhesive tape, it can effectively reduce the material cost and contribute to the sustainable development of the medical industry.
[0032] In this embodiment, there are 3 buckles 30 on one side of the arc-shaped clamping plate 10, allowing 3 straps to be threaded through simultaneously. Thus, the 3 straps are respectively bound to the patient's head, ear, and neck to strengthen the fixing effect of the tracheal intubation 100. Of course, in other embodiments, the number of buckles 30 can also be one or two. This embodiment is only an example rather than a limitation.
[0033] Refer to Figure 3 , the semi-closed clamping opening 11 is a semi-closed circular hole, and the central angle of the semi-closed circular hole is 200° - 270°. Preferably, in this embodiment, the central angle of the semi-closed circular hole is 260°. The central angles of the male thread sleeve 21 and the female thread sleeve 22 are the same as the central angle of the semi-closed circular hole. This design can ensure that while the tracheal intubation 100 can be inserted into the semi-closed clamping opening 11, it can ensure that there is more contact area for cooperation between the male thread sleeve 21 and the female thread sleeve 22, thereby improving the stability of the cooperation between the two arc-shaped clamping plates 10 and avoiding the loosening of the two arc-shaped clamping plates 10 due to unstable threaded cooperation between the male thread sleeve 21 and the female thread sleeve 22.
[0034] In addition, it should be noted that since the tracheal intubation 100 has a certain elasticity, when docking with the arc-shaped clamping plate 10, it can be inserted into the semi-closed clamping opening 11 with a central angle of 260° and elastically recover after insertion.
[0035] Refer to Figure 4 and Figure 5 On the outer wall of the male thread sleeve 21, there is an external thread 82, and on the inner wall of the female thread sleeve 22, there is an internal thread 81. The external thread 82 cooperates with the internal thread 81 to achieve the mating and locking between the male thread sleeve 21 and the female thread sleeve 22.
[0036] In practical applications, due to differences in patient body types, the sizes of the tracheal intubation 100 also vary slightly. In order to enable the arc-shaped clamping plate 10 to lock tracheal intubations 100 of different sizes, the present embodiment further proposes the following solution:
[0037] Refer to Figure 2 , Figure 4 and Figure 5 On the upper end surface of the male thread sleeve 21, there is an elastic shrinkage sleeve 41, and on the inner wall of the female thread sleeve 22, there is a stop structure that cooperates with the elastic shrinkage sleeve 41. The stop structure is used to squeeze the elastic shrinkage sleeve 41 so that the elastic shrinkage sleeve 41 shrinks inward to lock the outer wall of the tracheal intubation 100. It can be seen that through the setting of the elastic shrinkage sleeve 41, the size of the clamping opening formed by the male thread sleeve 21 is no longer fixed and can be adaptively adjusted according to the size of the tracheal intubation 100, meeting the locking of tracheal intubations 100 of different sizes and having a wider application range.
[0038] Specifically, refer to Figure 2 , on the outer wall of the elastic shrinkage sleeve 41, there is a first inclined surface 42 that inclines inward, and the stop structure is an annular step 51 arranged along the inner wall of the female thread sleeve 22. On the inner wall of the annular step 51, there is a second inclined surface 52 that inclines outward. It can be understood that during use, as the male thread sleeve 21 and the female thread sleeve 22 are tightened, the elastic shrinkage sleeve 41 and the annular step 51 will gradually approach each other. When the first inclined surface 42 and the second inclined surface 52 of the two come into contact, due to the interaction of the inclined surfaces, a radially inward force will be generated, which will cause the elastic shrinkage sleeve 41 to shrink inward along its radial direction, and then closely fit on the outer wall of the tracheal intubation 100. As the male thread sleeve 21 and the female thread sleeve 22 continue to be tightened, the contact area between the first inclined surface 42 and the second inclined surface 52 will gradually increase, making the elastic shrinkage sleeve 41 shrink more, so as to adapt to tracheal intubations 100 with smaller diameters.
[0039] Furthermore, refer to Figure 4, an inner folding groove 60 is provided at the connection between the elastic shrinkage sleeve 41 and the male threaded sleeve 21. It can be understood that due to the existence of the inner folding groove 60, when the elastic shrinkage sleeve 41 is squeezed, the elastic shrinkage sleeve 41 will be guided by the inner folding groove 60 and retract along a preset crease or path. This directional retraction ensures that the elastic shrinkage sleeve 41 can evenly wrap and lock the outer wall of the tracheal intubation 100.
[0040] Furthermore, a clamping strip 43 is provided on the inner wall of the elastic shrinkage sleeve 41. The clamping strip 43 can be specifically made of silica gel or rubber, aiming to increase the friction between the elastic shrinkage sleeve 41 and the tracheal intubation 100 when the elastic shrinkage sleeve 41 shrinks, improve the locking effect on the tracheal intubation 100, and prevent its axial movement.
[0041] Refer to Figure 4 , at least one end face of the arc-shaped clamping plate 10 is provided with a flexible gasket 70. The flexible gasket 70 is arc-shaped. When the arc-shaped clamping plate 10 is fixed to the patient's mouth, the flexible gasket 70 fits around the patient's lips, which can minimize the trauma caused by the long-term wearing of the arc-shaped clamping plate 10 to the patient's mouth corners.
[0042] In summary, the oral tracheal intubation fixation device in the above embodiments of the present utility model can be tightly locked on the outer wall of the tracheal intubation 100 through the cooperation of the male threaded sleeve 21 and the female threaded sleeve 22, combined with the semi-closed bayonet 11 in the middle of the arc-shaped clamping plate 10. Subsequently, the strap can be fixed to the patient's neck or head. Compared with the method of fixing the tracheal intubation 100 with adhesive tape in the existing scheme, the operation is simpler and more convenient. And during the subsequent oral care process, the tracheal intubation 100 can be adjusted by simply loosening the strap, without causing additional discomfort to the patient.
