DETAILED DESCRIPTION

[0018] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0019] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0020] refer to Figure 1 or Figure 3 , Figure 4 The tongue-bite prevention device of the present application comprises two cross-connected strip-shaped pressure plates 100, wherein the two bifurcated parts formed by the two strip-shaped pressure plates 100 are used to spread the patient's teeth (i.e., supported between the patient's upper and lower teeth), and the other bifurcated part is used to be exposed outside the patient's oral cavity.

[0021] The overall structure of the pressing plate 100 can refer to a conventional tongue depressor, and its end can be directly set to a semicircular shape or a certain arc transition can be used at the top angle of the end. The material of the pressing plate 100 can be plastic or bamboo, and this type of material is generally used as a disposable item; if it needs to be repeatedly disinfected, a metal material (such as stainless steel or titanium alloy) can be used. When in use, since the two pressing plates 100 are forked from each other, they have enough width to support between the patient's teeth, especially between the teeth on both sides of the oral cavity, overcoming the shortcomings of using a single tongue depressor.

[0022] Continue to refer Figure 1 , Figure 2 In at least one embodiment, the tongue bite prevention device further includes a protective cover 300 made of a soft material, which at least covers the end of the pressing plate 100 for holding the teeth apart. The material selection of the protective cover 300 is diverse, and gauze, adhesive tape, and silicone etc. can be selected. After using the protective cover 300, it can not only increase the thickness of the pressing plate 100, but also protect the pressing plate 100, further avoiding the pressing plate 100 from being bitten or broken. At this time, regardless of whether the pressing plate 100 is disposable or can be reused after disinfection, the protective cover 300 should be used as a disposable item and should be discarded and disposed of harmlessly after use.

[0023] If a material that is easy to shape, such as silicone, is used, the present application also provides an optional protective sleeve structure. Figure 2The protective sleeve 300 includes a groove-shaped bite portion 310 and a jacket portion 320, and a connecting strip 330 connected between the first two; the bite portion 310 is sleeved on the end of the pressing plate 100 for spreading the teeth; the jacket portion 320 is sleeved on the end of the pressing plate 100 for being exposed outside the oral cavity; and the connecting strip 330 is distributed along the edge of the pressing plate 100. In this way, through the pulling action of the jacket portion 320 and the connecting strip 330, the bite portion 310 can be tightly sleeved on the pressing plate 100, avoiding easy falling off during use.

[0024] The connection between the two pressing plates 100 can be a fixed connection or a rotational connection.

[0025] When the fixed connection method is selected, the overall structure and preparation of the protector are simpler, but products of different specifications need to be prepared to cope with patients with different oral sizes.

[0026] When the rotating connection is used, the opening size between the two pressing plates 100 can be adjusted to accommodate patients with different oral sizes, and the applicability is better; thus, in at least one embodiment, the tongue bite prevention device further includes a hinge 200, which is connected to the intersection of the two pressing plates 100, and the pressing plates 100 can rotate around the hinge 200. The hinge 200 is a relatively conventional part, and specifically, a structure similar to a rivet or a bolt can be used, in which a rod or shaft in the middle simultaneously passes through the two pressing plates 100, and then the two ends are sleeved or fixed with a larger head (such as a nut) to prevent falling off.

[0027] When the hinge 200 is used, the two pressure plates 100 can use conventional straight tongue depressor structures. Figure 3 , 4 and 5. In at least one embodiment, the middle portion of one of the pressing plates 100 is concave to form a U-shaped groove 110, the width between the side walls of the U-shaped groove 110 is greater than the width of the other pressing plate 100, and the other pressing plate 100 is cross-connected in the U-shaped groove 110. Further, the depth of the U-shaped groove 110 is equal to the thickness of the pressing plate 100 cross-connected therein. After using the pressing plate 100 with this structure, although the rotation angle of the pressing plate 100 is limited, the top and bottom surfaces of the two pressing plates 100 can be kept flush with each other, which is more stable when used to open the teeth.

[0028] In order to ensure that the two pressing plates 100 remain stable after being rotated to a suitable angle, refer to Figure 3 , 4, 6 and 7, in at least one embodiment, the tongue-biting protection device further comprises a locking assembly 400. The locking assembly 400 comprises a rack 410 and a clamping seat 420, which are respectively fixedly connected to the exposed ends of the two pressing plates 100; the clamping seat 420 protrudes from the pressing plate 100 and is provided with a through first slide groove 421; one end of the rack 410 is fixedly connected to the pressing plate 100, and the other end is slidably connected to the first slide groove 421; the side wall of the first slide groove 421 is provided with a retractable clamping block 423, which is used to clamp the rack 410 after being extended.

[0029] Furthermore, the rack 410 is in an arc shape, and the center of the circle is located at the position of the hinge 200 .

[0030] Furthermore, the clamping seat 420 is also provided with a second slide groove 422, one end of which is connected to the side wall of the first slide groove 421, and the other end is sealed and located at the outermost end of the pressing plate 100; the clamping block 423 is slidably connected to the second slide groove 422, and one end of which is set as a tip, and the other end is fixedly connected to a connecting rod 426, the connecting rod 426 is sleeved with a spring 424 and one end is passed through to the outside of the sealed end of the second slide groove 422, and the end that passes through the outside is fixedly connected to an auxiliary pull plate 425. Among them, the auxiliary pull plate 425 should have a certain length to facilitate pulling the connecting rod 426, and preferably have a certain curvature to facilitate pulling.

[0031] Furthermore, the second slide groove 422 is a dovetail groove or a T-shaped groove ( Figure 7 The longitudinal section of the block 423 is a trapezoid or T-shaped shape that matches the former shape. In this way, the block 423 can be prevented from falling off when sliding.

[0032] When in use, the connecting rod 426 is first pulled out partially through the auxiliary pull-out plate 425, so that the tip of the block 423 can be separated from the rack 410, so that the opening angle between the two pressing plates 100 can be adjusted by rotating the pressing plate 100. After the angle is adjusted, the auxiliary pull-out plate 425 is released. At this time, under the elastic force of the spring 424, the tip of the block 423 is re-engaged on the rack 410, thereby locking the opening angle of the two pressing plates 100.

[0033] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
