[0018] This embodiment provides an endotracheal tube device with a snap-on bite block, and the bite block assembly provided in the endotracheal tube device can be stably positioned on the tube body 1.

[0019] For ease of description, the two ends of the endotracheal tube device are referred to as the "tail end" and the "tip end".

[0020] in,

[0021] The tail end refers to the end of the endotracheal tube device that is outside the patient's body;

[0022] The tip is the end of the endotracheal tube device that is inserted into the patient's trachea.

[0023] See also Figure 1 and Figure 2 The endotracheal catheter device of this embodiment includes a catheter body 1 and a bite block assembly 2, and the bite block assembly 2 is sleeved on the catheter body 1 as a whole.

[0024] More specifically,

[0025] The tooth pad assembly 2 includes a tooth pad sleeve 21 and a buckle sleeve 22 .

[0026] The bite block sleeve 21 is sleeved on the outside of the catheter body 1 , and the bite block sleeve 21 is located on a side close to the tail end of the airbag.

[0027] The tooth pad sleeve 21 is fixedly provided with a butterfly wing 23, which is arranged on the side of the middle part of the tooth pad sleeve 21 that is biased toward the tip. The butterfly wing 23 divides the tooth pad sleeve 21 into two sections, wherein the section close to the tip is called the tooth pad section, and the section close to the tail end is called the buckle section. The tooth pad section is used to be placed on the patient's teeth to prevent the patient from biting the catheter body 1, and the buckle section is used to set a buckle tightening mechanism.

[0028] A flange structure facing outward is provided on one end of the tooth pad sleeve 21 close to the rear end, and the flange structure is called a convex stop 211 .

[0029] The snap sleeve 22 is sleeved on the tooth pad sleeve 21, and the snap sleeve 22 can move back and forth on the tooth pad sleeve 21. The snap sleeve 22 is located between the butterfly wing 23 and the convex stop 211. In this way, the snap sleeve 22 is restricted in the range between the butterfly wing 23 and the convex stop 211, and can slide back and forth along the tooth pad sleeve 21 within this range.

[0030] The tooth pad sleeve 21 is provided with a notch, which is called a pressure pipe opening 212. The pressure pipe opening 212 is provided on a side close to the tail end of the butterfly wing 23, that is, between the butterfly wing 23 and the convex stop 211, close to the butterfly wing 23. The pressure pipe opening 212 is within the sliding range of the buckle sleeve 22.

[0031] A small hole is also provided on the butterfly wing 23 , which is called a buckle hole 231 . The buckle hole 231 is opened corresponding to the pressing pipe opening 212 , or in other words, the buckle hole 231 is opened at a position on the butterfly wing 23 closest to the pressing pipe opening 212 .

[0032] The buckle sleeve 22 is also provided with a buckle top plate 221, which is provided at a side portion of the buckle sleeve 22 close to the butterfly wing 23 and extends an end toward the butterfly wing 23, which is called a buckle end 222, and the buckle end 222 faces the buckle hole 231 provided on the butterfly wing 23. The buckle top plate 221 is flat as a whole and has a certain elasticity, and can be bent by force and then released to rebound.

[0033] A hook is arranged on the buckle end 222 of the buckle top plate 221, and the hook faces outward away from the tooth pad sleeve 21. A small bulge is also arranged in the middle of the buckle top plate 221, and the small bulge is called a top pressure head 223, and the top pressure head 223 faces the tooth pad sleeve 21 inside.

[0034] The buckle top plate 221 is set for the buckle hole 231 and the pressure pipe opening 212. Specifically, the buckle end 222 is set for the buckle hole 231, and the top pressure head 223 is set for the pressure pipe opening 212. The buckle end 222 of the buckle top plate 221 can be inserted into the buckle hole 231. Under the effect of the self-rebound force of the buckle top plate 221, the hook on the buckle end 222 can hook the edge of the buckle hole 231 to achieve a buckle effect. When the buckle end 222 of the buckle top plate 221 is buckled with the buckle hole 231 of the butterfly wing 23, the top pressure head 223 on the buckle top plate 221 is just at the pressure pipe opening 212, and the top pressure head 223 is pressed on the catheter body 1 inside the tooth pad sleeve 21 through the pressure pipe opening 212, so that the entire tooth pad assembly 2 can be positioned on the catheter body 1.

[0035] In essence, the combination of the buckle pressing plate 221 , the buckle hole 231 and the tube pressing port 212 constitutes a buckle pressing mechanism, which can press the catheter body 1 , so that the bite block assembly 2 is positioned on the catheter body 1 .

[0036] In order to facilitate the fixation of the dental pad assembly 2 to the patient's mouth, a tape roll is also provided on the buckle sleeve 22 (not shown in the figure, but can be understood by those skilled in the art). After the tape roll is unfolded, there are two tapes with a width of 1 cm and a length of 10 cm on each side (a total of four tapes).

[0037] In addition, the tracheal tube device of this embodiment also includes an anti-drop strip 3, which is attached to the catheter body 1 and is located on the side of the bite pad assembly 2 close to the tip. Its function is to prevent the bite pad assembly 2 from slipping and affecting the intubation operation when the intubation operation is performed. When the intubation operation is completed, the anti-drop strip 3 is removed from the catheter body 1.

[0038] In this embodiment, the anti-dropping strip 3 is a common sticker. In other embodiments, other forms of anti-dropping strips, such as medical adhesive tape, may also be used.

[0039] Preferably, in other embodiments, two symmetrical snap-on tightening plates 221 may also be provided on the snap-on sleeve 22, and "two pressing tube openings 212 are opened on the tooth pad sleeve 21" and "two snap-on holes 231 are provided on the butterfly wing 23" in a targeted manner. In this way, the catheter body 1 is tightened on both sides of the catheter body 1 at the same time, so that a better tightening and positioning effect can be achieved.

[0040] The tracheal tube device of this embodiment is used and operated as follows:

[0041] According to conventional practice, the tip of the tracheal tube device is inserted into the trachea of ​​the patient through the mouth of the patient. After confirming that the intubation operation is completed, the anti-dropping strip 3 on the catheter body 1 is peeled off, and the tooth pad assembly 2 falls along the catheter body 1 to the patient's mouth, the butterfly wings 23 are fitted to the patient's teeth, and the buckle sleeve 22 is pressed down to buckle it with the tooth pad sleeve 21. At this time, under the tightening action of the pressure tube mouth 212, the entire tooth pad assembly 2 is positioned on the catheter body 1; then, the tape roll at the buckle sleeve 22 is unfolded, the protective paper is torn off, and the four tapes are cross-fixed at the upper right and lower right, upper left and lower left positions of the patient's mouth, so that the entire tooth pad assembly 2 is positioned at the patient's mouth.

[0042] The tracheal tube device of this embodiment has the following innovative effects:

[0043] In the tracheal tube device of this embodiment, the bite pad assembly 2 is of a snap-on type, and when the bite pad sleeve 21 and the snap sleeve 22 are snapped together, the snap-on top plate 221 can press against the tube body 1, so that the entire bite pad assembly 2 can be stably positioned on the tube body 1, so that the bite pad assembly 2 can always be located at the patient's teeth, and with the use of the tape roll, the bite pad assembly 2 will not fall off the patient's teeth, thereby ensuring that the tube body 1 will not be bitten by the patient, ensuring the smooth implementation of the treatment process. In addition, the operation and implementation of the tracheal tube device is very convenient, thereby simplifying the operation steps during the treatment process.

[0044] It should be noted that the actual endotracheal tube device should also include a balloon ( Figure 1 Left side of the orientation shown), air bag inflation port ( Figure 1 The right side of the orientation shown (not shown in the figure), tube core, etc., since these components are common knowledge known to those skilled in the art, they will not be described in detail in this article.
