Description

Technical Field

[0001] The utility model relates to the field of dental pads, in particular to a disposable dental pad for fixing a tracheal tube in a prone position. Background Art

[0002] At present, when intubating a patient's mouth, the cannula needs to be fixed on a bite pad with medical tape. The bite pad is set in the patient's mouth and the patient's teeth can bite the bite pad. The doctor almost judges the position of the bite pad to fix the cannula based on experience. When the cannula is too long or too short, it is easy to cause discomfort to the patient. The cannula needs to be taken out and the position of the bite pad needs to be readjusted, which is time-consuming and laborious. A bite pad needs to be used in the patient's mouth.

[0003] like Figure 7 and Figure 8 , is a traditional bite pad 5, the outer wall of which is provided with a second supporting portion 51, and the middle part of the bite pad 5 is provided with a through hole 50, and the upper part of the bite pad 5 is fixed to the cannula 6 by a medical tape 7, and the patient can bite the lower part of the bite pad 5, while the cannula 6 and the lower part of the bite pad 5 are not fixed, and the cannula 6 located in the patient's mouth may be offset, and the bite pad 5 cannot effectively fix it, and the fixing effect is poor, and the patient's mouth may bite the cannula 6, causing deformation or even damage of the cannula 6, affecting the normal delivery of gas. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a disposable bite pad for fixing a tracheal tube in a prone position, which solves the technical problem that the fixation effect of the bite pad is poor, the patient may bite the tube, causing deformation or even damage of the tube, and affecting gas delivery.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A disposable mouth guard for fixing an endotracheal tube in a prone position comprises a mouth guard body, wherein the mouth guard body comprises a bite portion and a fixing portion connected to the bite portion, wherein the bite portion and the fixing portion are arranged in a longitudinal direction, wherein the cross-sectional area of ​​the bite portion is larger than that of the fixing portion, wherein a fixing hole for fixing the tube is arranged in the middle of the fixing portion, wherein a longitudinally arranged notch is arranged on a side wall of the fixing portion, wherein the notch is connected to the fixing hole, and wherein a supporting portion is arranged on the side wall of the mouth guard body, wherein the supporting portion can be pressed against a person's teeth or mouth.

[0007] Further:

[0008] The biting part is a solid structure.

[0009] The biting part is a cylindrical structure, and the fixing part is a cylindrical structure.

[0010] The supporting part is a sheet-like structure, and the supporting part extends from one end of the notch to the other end along the side wall of the tooth pad body.

[0011] The tooth pad body is made of silicone.

[0012] The inner wall of the fixing hole is provided with a plurality of anti-slip grooves.

[0013] A locking portion is provided on the fixing portion at the notch, and the locking portion can fix and lock the notch.

[0014] The locking part includes a folding part swingably arranged on the tooth pad body, and at least one groove arranged on the tooth pad body. The folding part is provided with a convex point corresponding to the groove, and the convex point can be fixed in the groove by extrusion deformation.

[0015] The biting part is provided with a reinforcement part at the lower part of the supporting part.

[0016] The fixing part comprises a cylindrical part located at the lower end of the supporting part and an arc part located at the upper end of the supporting part. The fixing hole at the cylindrical part is a vertical structure, and the fixing hole at the arc part is an arc-shaped structure.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] The cannula can be installed in the fixing hole, which not only has a good fixing effect on the cannula in the mouth, but also has a good protective effect on the cannula, preventing the cannula from being bitten by the patient. There is no need to use tape to fix the cannula, which is convenient for adjusting the position of the cannula. The cross-sectional area of ​​the bite portion is larger than the cross-sectional area of ​​the fixing portion, and the patient is not easy to bite the fixing portion, which better protects the cannula; further, the bite portion is a solid structure, which can have a strong bite resistance. When the patient's bite force is large, the bite portion is deformed smaller to prevent the fixing portion from being bitten by the force and damaging the cannula. The bite portion can also return to its original shape after deformation and is not easy to deform; further, the anti-slip groove can improve the fixing effect and prevent the cannula from moving; further, the locking portion can strengthen the fixing effect and prevent the cannula from moving; further, the locking portion is fixed by convex points and grooves, and disassembly and assembly are convenient and quick; further, the reinforcement portion can enhance the bite resistance and prevent deformation; further, the arc structure can enhance the friction between the cannula and the cylindrical portion to prevent the cannula from moving.
