Technical Field
[0001] This utility model relates to the field of medical devices, specifically a mouthpiece suitable for radiotherapy of nasopharyngeal carcinoma. Background Technology
[0002] Nasopharyngeal carcinoma is a malignant tumor that occurs in the nasopharyngeal mucosa. It has the highest incidence rate among malignant tumors of the ear, nose, and throat. Common clinical symptoms include nasal congestion, bloody nasal discharge, a feeling of fullness or blockage in the ears, hearing loss, double vision, and headache. With the increasing severity of environmental pollution, more and more patients with nasopharyngeal carcinoma are being diagnosed. Most nasopharyngeal carcinomas are moderately sensitive to radiotherapy, which is the preferred treatment method. However, for cases of highly differentiated carcinoma, advanced disease, or recurrence after radiotherapy, surgical resection and chemotherapy are also indispensable. When using radiotherapy for nasopharyngeal carcinoma, patients are required to open their mouths and fix their tongues.
[0003] Currently, some mouthpieces for radiotherapy are used during radiotherapy, but they have some problems, such as limited size, requiring the preparation of multiple sizes and models to meet the needs of different patients, and the mouthpiece easily sliding in the patient's mouth during radiotherapy. These issues prevent their widespread application. Therefore, the usual practice is still to use a tongue depressor wrapped with adhesive tape or to insert a small medicine bottle into the patient's mouth to open the mouth and fix the tongue. This method is not standardized and its effect on opening the mouth and fixing the tongue is not ideal. Therefore, there is an urgent need to disclose a radiotherapy mouthpiece that is simple in structure, easy to use, suitable for different mouth sizes, and does not easily slide after being bitten down.

The top of the tongue muscle training block 6 is rotatably connected to a shaking block 8 via a pivot pin. A sterile magnetic ball 9 is provided on the inner side of the shaking block 8. By setting the Y-shaped support rod 1 and the alveolar bite pad 4 together, it can be adapted to different mouth sizes. During use, the teeth can bite the alveolar bite pad 4, which is less likely to slip. By using the shaking block 8 and the tongue muscle training block 6 together, the patient's tongue can be efficiently positioned, which is beneficial for the patient to perform tongue muscle training.
[0027] Reference Figure 2 and Figure 3 A rubber cord 10 is movably sleeved on the surface of the Y-shaped support rod 1. One end of the rubber cord 10 is fixedly connected to a sealing plug 11, which is inserted into the inner cavity of the water inlet 5. By setting the rubber cord 10 and the sealing plug 11 to cooperate, the water inlet 5 can be blocked. After the sealing plug 11 is removed from the inner cavity of the water inlet 5, it is convenient for the patient to add ice water into the inner cavity of the Y-shaped support rod 1.
[0028] Reference Figure 3 A positioning ring 12 is fixedly sleeved on the surface of the Y-shaped support rod 1, and the inner cavity of the positioning ring 12 is in contact with the surface of the rubber rope 10.

[0033] Working principle: When in use, the patient removes the mouthpiece from the inner cavity of the protective shell 14 and opens the sealing plug 11. Then, ice water is injected into the inner cavity of the Y-shaped support rod 1. After injection, the sealing plug 11 is used to seal the water inlet 5. Then, the alveolar bite pad 4 is placed in the mouth, and the patient bites the alveolar bite pad 4 with their teeth to improve the stability of the mouthpiece. Then, the one-way valve 3 is opened, and the balloon 2 is squeezed by hand. The balloon 2 pushes the ice water upward, so that the ice water in the inner cavity of the Y-shaped support rod 1 flows into the patient's mouth or tongue through the outlet 7 for swallowing treatment. When the patient needs to perform tongue muscle training, they curl their tongue and insert it into the surface of the tongue muscle training block 6. The shaking block 8 is used to move the patient's tongue, which helps the patient to perform tongue muscle training. After training, the patient opens the protective shell 14 and puts the mouthpiece inside. This can protect the mouthpiece from dust and improve the safety of the patient when carrying it.
