[0024] like Figure 1 and Figure 3 The invention relates to a mouth opening trainer for patients with limited mouth opening due to lip scarring, which includes a mouth mouth body 1, and a water collection cup 2 is detachably connected to the bottom end of the mouth mouth body 1.

[0025] The mouthpiece body 1 has a support arm 3 at one end on each side, and a V-shaped corner support 4 at the other end of the support arm 3. The V-shaped corner support 4 includes a V-shaped bracket 401 and an outer wrapping layer 402 disposed on the outer wall of the V-shaped bracket 401. The outer wrapping layer 402 is made of medical-grade wear-resistant and corrosion-resistant material. Preferably, the outer wrapping layer 402 in this application is made of silicone material, which facilitates contact with the oral cavity, reduces harm to the human body, and is easy to clean and disinfect.

[0026] The support arm 3 is an adjustable length arm.

[0027] In use, this invention first connects the water collection cup 2 to the mouthpiece body 1, then places the mouthpiece body 1 into the mouth, with the two V-shaped mouth corner supports 4 fitting into the two corners of the mouth. The two V-shaped mouth corner supports 4 provide support for the mouth opening restricted by burn scarring. After a certain period of support, the trainer can be removed. Through repeated mouth opening support, training is achieved for the mouth opening restricted by burn scarring. Compared to self-training, this application uses a trainer to provide mouth opening support training for the mouth opening restricted by burn scarring. This invention improves the efficiency of mouth corner training for patients with restricted lip scars without requiring surgery, thus reducing the risk of wound infection. The support arm 3 in this application is an adjustable arm, which can be adjusted according to the size of the mouth after the lip scar is restricted. This allows for adjustment of the distance between the two V-shaped mouth corner supports 4, thereby adapting to mouth corner training for different people or at different stages. During training, oral secretions (such as saliva) accumulate and flow through the bite body 1 to the water collection cup 2 at the bottom, facilitating the collection and treatment of oral secretions.

[0028] In a preferred embodiment, the water collecting cup 2 is provided with a funnel-shaped water collecting cover 201 at the mouth of the cup. The water collecting cover 201 and the water collecting cup 2 are integrally formed, which improves the integrity and structural strength between the water collecting cup 2 and the water collecting cover 201. The funnel-shaped water collecting cover 201 avoids pollution caused by leakage of oral secretions.

[0029] The water collection cup 2 is provided with a connecting part 202, and the connecting part 202 is provided with an internal thread. The bottom end of the mouthpiece body 1 is provided with an external thread. The water collection cup 2 and the mouthpiece body 1 are connected by a thread, which facilitates the connection and disassembly of the water collection cup 2 and the mouthpiece body 1, and facilitates the rapid centralized treatment of oral secretions.

[0030] A holding groove 203 is formed between the outer wall of the connecting part 202 and the inner wall of the water collecting cup 2, which facilitates the collection of oral secretions through the holding groove 203.

[0031] In a preferred embodiment, the bite body 1 of this application includes an inner support column 101 and an outer support layer 102 disposed on the outer wall of the inner support column 101. The outer support layer 102 is made of silicone material. The inner support column 101 provides support for the bite body 1, giving it a certain structural strength and facilitating the bearing of the support arm. The outer support layer 102 facilitates contact between the bite body 1 and the oral cavity, achieving soft contact and preventing the bite body 1 from causing damage to the oral cavity.

[0032] The support arm 3 in this application includes an inner support rod 301 and an outer support rod 302. One end of the inner support rod 301 is connected to the bite body 1, and the other end of the inner support rod 301 is an inner free end. One end of the outer support rod 302 is connected to the V-shaped mouth corner support 4, and the other end of the outer support rod 302 is an outer free end. The inner support rod 301 near the inner free end is provided with a plurality of inner connecting holes 303, and the outer support rod 302 near the outer free end is provided with a plurality of outer connecting holes 304. After the inner free end is inserted into the outer free end, the inner connecting holes 303 and the outer connecting holes 304 are connected by a connecting post 305. When the length of the support arm 3 needs to be adjusted, the inner free end can be moved within the outer free end to adjust the length of the inner support rod 301 extending beyond the outer support rod 302. After the overall length of the support arm 3 is adjusted to the correct position, the inner support rod 301 and the outer support rod 302 are fixed by inserting the connecting post 305 into the corresponding inner connecting hole 303 and outer connecting hole 304. This ultimately allows for the adjustment of the distance between the two V-shaped corner support devices 4 to accommodate different users or different stages of lip scar corner training.

[0033] Both the inner connecting hole 303 and the outer connecting hole 304 are positioned facing the bottom end of the bite body 1, effectively preventing the oral cavity or teeth from contacting the connecting post and causing damage to the oral cavity.

[0034] The support arm 3 has a V-shaped corner support 4 at one end that is higher than the end connected to the bite body 1, which helps to support the corners of the mouth upward and outward, conforming to the shape of the human mouth opening and reducing the pain of patients during training.

[0035] The bite body 1 is provided with a guide groove 103 in the vertical direction. The bottom end of the guide groove 103 is connected to a guide cover 104. The guide groove 103 is designed to guide oral secretions, which can improve the collection efficiency of oral secretions in the water collection cup 2. The guide cover 104 is designed to guide oral secretions to the holding tank 203, preventing oral secretions from flowing into the connecting part, and facilitating the cleaning of the water collection cup 2.

[0036] The bite body 1 described in this application consists of a horizontal segment 1a and a vertical segment 1b, which are connected by an arc-shaped segment 1c. The horizontal segment 1a, arc-shaped segment 1c, and vertical segment 1b are integrally formed, with the horizontal segment 1a extending into the oral cavity. A water collection cup 2 is detachably connected to the bottom end of the vertical segment 1b. The integrally formed horizontal segment 1a, arc-shaped segment 1c, and vertical segment 1b improve the overall integrity and structural strength of the bite body 1. In this application, the horizontal segment 1a extends into the oral cavity; when the patient uses it, they bite down on the horizontal segment 1a, thus connecting the oral cavity with the bite body 1 and providing support for the corners of the mouth with the V-shaped corner support 4. The arc-shaped segment 1c connects the horizontal segment 1a and vertical segment 1b; when the patient bites down on the horizontal segment 1a, the arc-shaped segment 1c contacts the lower lip, achieving flexible contact between the bite body 1 and the lower lip, preventing damage to the lower lip. Compared to designs with only a vertical segment 1b, where the patient needs to keep their head down to ensure oral secretions flow into the collection cup 2 while using the trainer, the horizontal segment 1a allows the patient's head to remain in a natural position during training. Oral secretions generated during training can also flow into the collection cup 2 through the horizontal segment 1a, the curved segment 1c, and the vertical segment 1b, avoiding the need for the patient to keep their head down to ensure secretions enter the collection cup and reducing the pain associated with support training. As a preferred embodiment, the horizontal segment 1a and the vertical segment 1b are perpendicular or at an obtuse angle, which facilitates the flow of oral secretions into the collection cup 2 under gravity through the vertical segment 1b, preventing spillage.
