[0026] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0028] like Figures 1 to 3 As shown, the tooth pad device of the present invention comprises a tooth pad 1 and an external fixing member 2.

[0029] The bite block 1 comprises a bite block body 11 and a plurality of internal fixing wings 12. The bite block body 11 may have a shape of a cube, a cuboid or a square pyramid.

[0030] The internal fixing wing 12 extends from the outer surface of the tooth pad body 11 to form a molar fixing groove 13 that matches the upper molar and / or lower molar between the internal fixing wing 12 and the tooth pad body 11. When the tooth pad 1 is placed between the molars, the end surface of the crown of the molar contacts the outer surface of the tooth pad body 11, and the internal fixing wing 12 abuts against the side of the crown of the molar, thereby positioning the molar in the molar fixing groove 13 formed by the internal fixing wing 12 and the tooth pad body 11, stably opening the oral cavity. The internal fixing wing 12 can usually be made of a flexible material, such as silicone.

[0031] One end of the external fixing member 2 is connected to the tooth pad body 11, and the other end of the external fixing member 2 is provided with a mouth corner fixing portion 21. The external fixing member 2 can be connected to the tooth pad body 11 by gluing, threading, plastic welding, etc. The mouth corner fixing portion 21 positions the external fixing member 2 at the mouth corner, thereby effectively avoiding problems such as displacement of the tooth pad device. The mouth corner fixing portion 21 can, for example, have a hook-shaped structure, or the mouth corner fixing portion 21 can have a suction cup structure.

[0032] In specific implementation, the external fixing member 2 can be made of metal, so that the external fixing member 2 and its mouth corner fixing portion 21 can be adjusted to a suitable shape according to the needs of different users. Alternatively, the external fixing member 2 can be provided with a bendable and deformable portion, so that the mouth corner fixing portion 21 of the external fixing member 2 can be adjusted to a suitable position at the bendable and deformable portion.

[0033] The tooth pad body 11 of the tooth pad device provided by the utility model can be placed between the molars, and the tooth pad body 11 is further fixed between the molars by the internal fixing wings 12, and the tooth pad is stably positioned at the corner of the mouth by the external fixing member 2, thereby reliably preventing the upper and lower incisors from closing without occupying the space of the incisors.

[0034] In one embodiment of the bite pad device of the present invention, the longitudinal section of the bite pad body 11 is wedge-shaped, and the height of the longitudinal section of the bite pad body 11 gradually increases along the direction from the molar to the incisor. The bite pad body 11 with such a cross-sectional shape can improve the comfort of the bite pad device and withstand a more balanced bite force of the user, thereby improving the reliability of the bite pad device.

[0035] In one embodiment of the tooth pad device of the utility model, in order to improve the comfort of use and the reliability of fixation, the internal fixing wing 12 has an arc-shaped structure. Generally, the internal fixing wing 12 corresponding to the same molar can be arranged in a mirror-symmetrical manner.

[0036] Furthermore, the inner arc surface of the inner fixing wing 12 faces the molar fixing groove 13 .

[0037] In one embodiment of the bite block device of the present invention, in order to improve the safety of use, the bite block body 11 and the inner fixing wing 12 are integrally formed.

[0038] In one embodiment of the bite block device of the utility model, the bite block body 11 is provided with an external fixing member connection hole 111, and the external fixing member 2 is connected to the external fixing member connection hole 111. The external fixing member 2 can be interference fit with the external fixing member connection hole 111 to achieve the connection between the two; or the external fixing member 2 can be glued or threadedly connected to the external fixing member connection hole 111.

[0039] In one embodiment of the tooth pad device of the utility model, the corner of mouth fixing part 21 has a hook-shaped structure, and the corner of mouth fixing part 21 is used to hook on the corner of mouth. In specific implementation, the outer surface of the corner of mouth fixing part 21 can be plastic coated to improve the comfort of the corner of mouth fixing part 21 when hooked on the corner of mouth.

[0040] In one embodiment of the tooth pad device of the present invention, the mouth corner fixing portion 21 is made of a plastic material to achieve flexible adjustment of the shape of the mouth corner fixing portion 21. The plastic material can be, for example, a metal material or a plastic plastic material.

[0041] Furthermore, the external fixing member 2 is made of metal.

[0042] In one embodiment of the tooth pad device of the utility model, an inner channel 112 is provided in the tooth pad body 11, an outer channel 22 is provided in the outer fixing member 2, and the inner channel 112 and the outer channel 22 are connected to form an oxygen supply channel. During the use of the tooth pad device, oxygen can be supplied to the user from the oxygen supply channel through the oxygen supply device, thereby enriching the function of the tooth pad device and improving the safety of the use of the tooth pad device.

[0043] In a specific implementation, the inner channel 112 can be combined with the external fixing component connection hole 111 to form the same channel structure, that is, the channel provided in the bite block body 11 serves as the external fixing component connection hole 111 and the inner channel 112 at the same time.
