The number of the protrusions 9 is at least 1. The connecting part 2 is provided with two retractable elastic ropes 11 for fixing the bite fixator in the oral cavity.

[0026] Further, the material of the inner oral part 1 is elastic silicone.

[0027] Embodiment 1

[0028] As Figures 1-4 shown in the figure, the present utility model provides a bite fixator for a tooth-protecting type tracheal catheter with enhanced fixation. The outer shape of the bite fixator is a columnar body. According to the positions of each part of the bite fixator during use, the columnar body is divided into an inner oral part 1, a connecting part 2, and an outer oral part 3; the connecting part 2 is located between the inner oral part 1 and the outer oral part 3;

[0029] An elastic buffer layer is provided on the outer surface of the inner oral part 1. The specific material of the elastic buffer layer is the elastic silicone layer 4; during use, the upper and lower tooth sockets of the patient are pried open, and the inner oral part 1 is inserted into the mouth, and the upper and lower tooth sockets of the patient bite on the inner oral part 1;

[0030] The outer diameter of the connecting part 2 is greater than the outer diameters of the in-oral part 1 and the out-of-oral part 3. The connecting part 2 is an annular protrusion, and during use, this connecting part 2 does not enter the mouth; a semi-circular groove 6 is provided along the outer edge of the connecting part 2, and the groove 6 is used to pass the tracheal catheter 5 and restrict the movement of the tracheal catheter 5;

[0031] The outer diameter of the in-oral part 1 should be greater than the outer diameter of the tracheal catheter 5. The groove 6 can also play a role in protecting the tracheal catheter 5 to avoid biting the tracheal catheter 5 when the upper and lower alveolar arches bite. Assuming that the positions where the upper and lower alveolar arches bite the in-oral part 1 correspond to the 12 o'clock and 6 o'clock directions of the annular connecting part 2, then the openings of the groove 6 are located at the 9 o'clock and 3 o'clock directions.

[0032] The shape of the out-of-oral part 3 is a cylindrical shape. An elastic belt-shaped fixing band 7 for wrapping and fixing the tracheal catheter 5 is provided around the outer periphery of the cylinder. One end of the fixing band 7 is axially fixed to the outer periphery of the cylinder along the out-of-oral part 3, and the other end of the fixing band 7 is in a free state. A square connecting head 8 is provided on the free side; the square connecting head 8 is provided in a square hollow shape, and the size of the hollow should be slightly larger than the size of the protrusion 9. The connecting head 8 is made of plastic; the fixing band 7 is a stretchable elastic body;

[0033] On the outer periphery along the axis of the out-of-oral part 3, there is also a square protrusion 9 for buckling the connecting head 8; the number of the protrusions 9 is set to 3 in parallel and equidistant. There is a slotted opening 10 on one side of the protrusion 9 for buckling the border of the connecting head 8. The height of the slotted opening 10 of the slotted opening is slightly larger than the thickness of the border of the connecting head 8, so that when the square hollow of the connecting head 8 is buckled on the protrusion 9, one side of the square border can be stuck in the slotted opening 10;

[0034] During use, the tracheal catheter 5 is inserted into the mouth closely against the semi-circular groove 6. Pick up the connecting head 8, stretch the fixing band 7 appropriately and wrap it around the outer periphery of the out-of-oral part 3 to surround the tracheal catheter 5, and then select a protrusion 9 at a suitable position and buckle the connecting head 8 on the protrusion 9; at this time, the fixing band 7 hugs the tracheal catheter 5 with a moderate tightness, which not only restricts the movement of the tracheal catheter 5 but also does not flatten the tracheal catheter 5, and the tracheal catheter 5 can still move forward or backward.

[0035] On the 12 o'clock direction and 6 o'clock direction of the annular connecting part 2, there are also two annular telescopic elastic ropes 11; by respectively putting the two elastic ropes 11 over the head above the auricle and around the neck below the auricle; the bite holder is fixed in the mouth.

[0036] Embodiment 2

[0037] The material of the in-oral part 1 is entirely elastic silicone. Other structures are the same as those in Embodiment 1.

[0038] The use of the present utility model:

[0039] 1. Pry open the upper and lower dental alveoli of the patient, insert part 1 in the oral cavity into the oral cavity; close the upper and lower dental alveoli and bite part 1 in the oral cavity; at this time, the connecting part 2 is outside the oral cavity.

[0040] 2. Pass the tracheal catheter 5 axially through the groove 6 along the bite holder and insert it into the patient's body.

[0041] 3. The elastic fixing band 7 wraps around the outer periphery of the tracheal catheter 5, and then the frame of the connecting head 8 is stuck in the slotted opening 10 of the protrusion 9; so that the tracheal catheter 5 is relatively fixed to the side of the bite holder.

[0042] 4. The two telescopic elastic ropes 11 fixed to the connecting part 2 are respectively put on the patient's head and neck along the upper and lower parts of the auricle, and the bite holder is fixed in the oral cavity.

[0043] The inner oral part 1 is provided with a silica gel layer 4. Since the texture of silica gel is more elastic than the hard plastic used in the inner oral part of the current bite guard, the compression on the patient's gums, lips and tongue surface will be much alleviated and it is not easy to form pressure sores; it reduces the irritation of the inner oral part to the patient, thereby reducing the patient's pain and the nursing difficulty. For comatose and trismus patients in clinical rescue, it can protect their teeth and play a buffering role.

[0044] The movable snap-fastener design provided by the connecting head 8, the elastic fixing band 7 and the protrusion 9 can be suitable for tracheal intubation of various sizes for precise fixation, with high fixing firmness. When fixing and removing the intubation, the operation is simple and convenient.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the present invention in any form or substance. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the premise of the present invention, several improvements and supplements can still be made, and these improvements and supplements should also be regarded as the protection scope of the present invention. Those who are familiar with this professional technology, without departing from the spirit and scope of the present invention, when making some minor changes, modifications and equivalent variations of the evolved, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments according to the essential technology of the present invention still fall within the scope of the technical solutions of the present invention.
