Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and particularly relates to a tongue protection tooth pad. Background Art

[0002] During the anesthesia process for patients with spinal deformities, they need to undergo neuroelectrophysiological monitoring. When monitored in the prone position, the tongue will also have slight movements due to the electric current stimulation. In addition, when the patient's tongue is too large, it is easy to bite the tongue when lying prone. Ordinary dental pads cannot match the tooth shape of many patients, causing the tongue to enter between the upper and lower teeth and cause bites, which does not provide overall protection for the tongue. Utility Model Content

[0011] a second fixed pad, the second fixed pad having a second telescopic channel along its length, and an end of the second fixed pad away from an outlet of the second telescopic channel being rotatably connected to the first telescopic bite pad;

[0012] The second telescopic pad is partially slidably disposed in the second telescopic channel.

[0013] Optionally, the peripheries of the central dental pad and the side dental pad are both covered with a soft bite layer.

[0014] Optionally, the soft biting layer is several layers of gauze.

[0015] Optionally, both the inner end and the outer end of the side bite pad are fixedly provided with a limiting portion for limiting the teeth from falling off the side bite pad.

[0016] Optionally, the limiting portion is a stop rod, and both ends of the stop rod are fixedly connected to the side tooth pads through connecting rods.

[0017] Optionally, there is a gap between the blocking rod and the side dental pad, and the blocking rod is covered with several layers of gauze.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] Example: Figure 1-Figure 3 As shown, this embodiment provides a tongue protection bite pad, including a middle bite pad 1 and a side bite pad 2; the middle bite pad 1 is for the patient's middle teeth to occlude, and the middle bite pad 1 has a hollow channel 11; the side bite pads 2 have two groups, respectively for the patient's teeth on both sides to occlude, and the two groups of side bite pads 2 are respectively installed on the opposite sides of the middle bite pad 1 through a ball hinge structure 3; each group of side bite pads 2 includes a first telescopic bite pad 21 and a second telescopic bite pad 22 with retractable length; one end of the first telescopic bite pad 21 is connected to the ball hinge structure 3, and the other end of the first telescopic bite pad 21 is rotatably connected to one end of the second telescopic bite pad 22 through a vertical rotating shaft 5.

[0028] Through the above arrangement, when in use, the patient's front teeth bite the outer periphery of the middle bite pad 1, and the angles of the first telescopic bite pad 21 and the second telescopic bite pad 22 are adjusted by the ball hinge structure 3 and the vertical rotating shaft 5, and the lengths of the first telescopic bite pad 21 and the second telescopic bite pad 22 are adjusted. After adjusting to the appropriate position, the patient's side teeth bite the side bite pads 2 on the corresponding sides respectively. The angle and length of the side bite pads 2 are adjustable, which can better match the tooth distribution shapes of different patients, better protect the tongue, and avoid the tongue being bitten by the teeth. It has good adaptability and also avoids the need to manufacture multiple pairs of bite pads with different tooth shapes, greatly reducing costs.

[0029] In a tongue protection bite pad of this embodiment, the first telescopic bite pad 21 includes a first fixed pad 211 and a first telescopic pad 212; the first fixed pad 211 has a first telescopic channel 2111 along the length direction; the end of the first fixed pad 211 away from the outlet of the first telescopic channel 2111 is connected to the ball joint structure 3; the first telescopic pad 212 is partially slidably arranged in the first telescopic channel 2111, and the outer end of the first telescopic pad 212 is rotatably connected to one end of the second telescopic bite pad 22.

[0030] Through the above arrangement, the length of the first telescopic bite pad 21 is adjusted by the telescopic cooperation of the first fixed pad 211 and the first telescopic pad 212 , which has a simple structure and is easy to adjust.

[0031] In the tongue protection bite pad of this embodiment, the second telescopic bite pad 22 includes a second fixed pad 221 and a second telescopic pad 222. The second fixed pad 221 has a second telescopic channel 2211 along its length. The end of the second fixed pad 221, distal from the exit of the second telescopic channel 2211, is rotatably connected to the first telescopic bite pad 21. The second telescopic pad 222 is partially slidably disposed within the second telescopic channel 2211. The telescopic cooperation between the second fixed pad 221 and the second telescopic pad 222 allows for adjustment of the length of the second telescopic bite pad 22, resulting in a simple structure and convenient adjustment.

[0032] In the tongue protection tooth pad of this embodiment, the periphery of the central tooth pad 1 and the side tooth pad 2 are both covered with a soft bite layer 4. This arrangement can effectively protect the patient's mouth and teeth, and the bite is more comfortable.

[0033] In the tongue protection tooth pad of this embodiment, the soft bite layer 4 is a plurality of layers of gauze. The structure is simple, the bite is comfortable, and the replacement is convenient, thereby reducing the cost and maintaining hygiene.

[0034] Optionally, after the first telescopic pad 212 and the second telescopic pad 222 are extended to an appropriate length, several layers of gauze are wrapped around the outer circumference of the first telescopic pad 212 and the second telescopic pad 222 to achieve the same outer diameter as the first fixed pad 211 and the second fixed pad 221, so as to facilitate the patient to stably bite the first telescopic pad 212 and the second telescopic pad 222 without the first telescopic pad 212 and the second telescopic pad 222 sliding.

[0035] In the tongue protection bite pad of this embodiment, both the inner and outer ends of the side bite pad 2 are fixed with a limiter 23 to prevent the teeth from leaving the side bite pad 2. This arrangement limits the patient's teeth between the two limiters 23 at the inner and outer ends, making the patient's bite more stable.

[0036] In the tongue protection tooth pad of this embodiment, the limiting portion 23 is a stopper rod, and both ends of the stopper rod are fixedly connected to the side tooth pad 2 through a connecting rod 24. This arrangement has a simple structure and stable installation.

[0037] In the tongue protection dental pad of this embodiment, there is a gap between the retaining rod and the side dental pad 2, and the retaining rod is covered with several layers of gauze. This arrangement makes it convenient to wrap gauze around the side dental pad 2 and the retaining rod separately, which has a better matching effect on the patient's teeth.

[0038] In the tongue protection bite pad of this embodiment, the limiting portions 23 are fixedly disposed on the first fixed pad 211 and the second fixed pad 221. This arrangement simplifies the structure and avoids excessive components that would affect the patient's occlusal comfort. The limiting portions 23 are only disposed on the first fixed pad 211 and the second fixed pad 221. When the first and second retractable bite pads 21 and 22 are in the extended state, the limiting portions 23 are spaced apart and distributed on the patient's side teeth, providing a good limiting effect.

[0039] In the tongue protection tooth pad of this embodiment, the outer peripheral walls of the first fixed pad 211, the first telescopic pad 212, the second fixed pad 221 and the second telescopic pad 222 are curved surfaces. The curved structure avoids damage to the patient's mouth and teeth, making it safer to use.
