Description

Technical Field

[0001] This utility model relates to the field of oral exercise equipment technology, and in particular to an oral support exercise device after radiotherapy for nasopharyngeal carcinoma. Background Technology

[0002] Nasopharyngeal carcinoma is a malignant tumor that occurs in the mucosal epithelium of the nasopharynx, often originating from the roof and lateral walls of the nasopharynx, especially the pharyngeal recess. It is one of the most common malignant tumors in southern my country. Radiotherapy for nasopharyngeal carcinoma is a local treatment method that uses high-energy rays (such as X-rays and gamma rays) to treat malignant tumors in the nasopharynx. Its principle is to destroy the DNA structure of cancer cells through radiation, inhibiting their proliferation and growth, thereby killing tumor cells and shrinking tumor lesions. However, radiotherapy for nasopharyngeal carcinoma can easily damage oral and pharyngeal tissues, leading to muscle fibrosis, trismus, and consequently affecting mouth opening and eating. Oral support exercise devices can gradually increase the range of mouth opening, maintain temporomandibular joint mobility, prevent or reduce fibrosis and adhesions, and help maintain normal oral physiological function.

[0003] Traditional oral support exercise devices are often designed with fixed sizes, making it difficult to accurately match each individual's oral cavity and reducing comfort during exercise. Furthermore, they don't allow users to visually track their progress, resulting in a lack of clear feedback during consistent practice. Users may not know if their mouth opening has improved or if the training intensity is appropriate, leading to confusion, frustration, or even doubt about the purpose of the exercise. Over time, this can easily weaken motivation and cause people to give up halfway. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an oral support exercise device after radiotherapy for nasopharyngeal carcinoma.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example like Figures 1 to 7As shown, the oral support exercise device for nasopharyngeal carcinoma after radiotherapy proposed in this utility model includes a support ring 1. An upper dental tray 2 and a lower dental tray 3 are arranged parallel to each other on one side of the support ring 1. The upper dental tray 2 and the lower dental tray 3 jointly support the teeth and expand with the inflation of the air bladder 13. The outer walls of both the upper dental tray 2 and the lower dental tray 3 are fitted with antibacterial rubber pads. These antibacterial rubber pads are usually made of rubber materials with antibacterial properties, commonly including natural rubber, synthetic rubber, or silicone. Antibacterial agents or antimicrobial additives are added to these rubber materials during the manufacturing process. These additives can inhibit the growth of bacteria and fungi, thereby preventing bacterial contamination and odor. An air bladder 13 is located in the middle of the upper dental tray 2 and the lower dental tray 3. After the air bladder 13 is inflated, it expands the upper dental tray 2 and the lower dental tray 3, enabling oral support exercise. An air supply tube 14 is fixedly connected to the air bladder 13, connecting the air bladder 13 and an air inflator 15 to conduct gas to inflate the air bladder 13. The end of the air supply pipe 14 furthest from the airbag 13 passes through the support ring 1 and is fixedly connected to an air inflator 15. The air inflator 15 inflates the airbag 13 through the air supply pipe 14, controlling the degree of inflation of the airbag 13. The air inflator 15 is usually made of plastic, metal, or rubber and is designed to connect the gas source and the inflation device, allowing gas to enter the object, such as an air cushion or airbag. The air inflator 15 has a one-way valve (also called a check valve), which only allows gas to flow in one direction. Once the gas enters the inflatable object, it will not flow out of the nozzle. After inflation, the airbag 13 is used to open the upper mouthguard 2 and the lower mouthguard 3. A measuring mechanism is provided on the side of the support ring 1 furthest from the upper mouthguard 2 and the lower mouthguard 3. The measuring mechanism is used to switch in conjunction with the upper mouthguard 2 and the lower mouthguard 3. A broadcasting mechanism corresponding to the measuring mechanism is installed on the measuring mechanism and the support ring 1.

[0022] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the measuring mechanism includes a pair of through holes 101 formed on the support ring 1. Each through hole 101 has a pair of first sliding grooves 11 inside. The first sliding grooves 11 allow the limiting rods 231 at both ends of the upper dental tray 2 and lower dental tray 3 to slide, restricting their movement trajectory and ensuring stable movement. Both ends of the upper dental tray 2 and lower dental tray 3 are fixedly connected to limiting rods 231 that slide within the first sliding grooves 11. Each end of the first sliding groove 11 of the upper dental tray 2 and lower dental tray 3 has a second sliding groove 12 inside. The second sliding groove 12 allows the first sliding rod 232 and the second sliding rod 234 to slide, cooperating with the limiting rod 231 to drive the pointer 233. The second sliding groove 12 is slidably connected to the first sliding rod 232 and the second sliding rod 234. One end of the first sliding rod 232 is connected to the limiting rod 231, and the other end carries the pointer 233. Sliding in the second sliding groove 12 drives the pointer 233 to indicate the mouth opening amplitude, which can trigger the contact sensor 54. The second slide bar 234 cooperates with the first slide bar 232 to keep the pointer 233 stationary, always pointing to the starting position, thus assisting in indicating the mouth opening amplitude. One end of both the first slide bar 232 and the second slide bar 234 is fixedly connected to the limiting rod 231. The support ring 1 is provided with an elliptical measuring ring 4, which allows the pointer 233 to slide, serving as a reference for measuring the mouth opening amplitude. It has measuring graduations with a structure similar to a ruler. The ends of the first slide bar 232 and the second slide bar 234 away from the limiting rod 231 are both fixedly connected to the pointer 233, which indicates the mouth opening amplitude on the elliptical measuring ring 4.

[0023] In addition, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the broadcasting mechanism includes a limiting groove 41 on one side of the elliptical measuring ring 4. The limiting groove 41 allows the limiting block 55 of the adjusting slider 5 to slide, restricting the movement trajectory of the adjusting slider 5. The adjusting slider 5 is slidably connected to the elliptical measuring ring 4. The adjusting slider 5 slides on the elliptical measuring ring 4 to set the target position, and the exercise progress is fed back through the arc-shaped positioning groove 53 and the contact sensor 54. A pair of locking blocks 51 are fixedly connected to the adjusting slider 5, locking the elliptical measuring ring 4 and fixing the position of the adjusting slider 5, which, together with the limiting block 55, enhances stability. One of the locking blocks 51 is fixedly connected to a limiting block 55 that slides into the limiting groove 41. The limiting block 55 slides into the limiting groove 41, enhancing the sliding stability of the adjusting slider 5. The rubber material can lock its position. The end of the limiting block 55 away from the locking block 51 has a spherical structure.

[0024] It is worth noting that, such as Figure 1 , Figure 4 and Figure 5As shown, the broadcasting mechanism also includes an arc-shaped positioning groove 53 on the adjusting slider 5. The arc-shaped positioning groove 53 accommodates the end of the first sliding rod 232 and has a contact sensor 54 inside, providing conditions for triggering the sensor. The contact sensor 54 is located inside the arc-shaped positioning groove 53. After being triggered by the first sliding rod 232, the contact sensor 54 transmits a signal to the controller, controlling the voice prompt device 52 to operate. The contact sensor 54 is a device that can sense contact with an object and convert it into an electrical signal. The outer wall of the support ring 1 is also fixedly connected to the voice prompt device 52. The voice prompt device 52 receives commands from the controller, broadcasts mouth opening data and progress, and provides feedback. The feedback language content is the pre-stored voice content, which is "You're great, you've improved again." The voice prompt device 52 is an electronic device that can convey specific information to the user through sound. Its main function is to automatically play pre-stored voice content under specific triggering conditions to achieve the purposes of prompting, warning, guiding, and greeting. Its core components typically include: a trigger module: receiving external signals (such as contact sensors, infrared sensors, buttons, radar, and light sensors), and starting voice playback when the triggering conditions are met. Voice storage and playback module: Built-in memory (such as Flash) is used to store voice files (supporting MP3 and WAV formats), and the voice is played out through a speaker or loudspeaker. Control module: Coordinates the logic of trigger signals and voice playback; some devices support multiple voice segments and custom trigger correspondences. After the contact sensor 54 is engaged in the arc-shaped positioning groove 53 through the end of the first slide rod 232, the voice prompt device 52 is activated. The voice prompt device 52 is electrically connected to the output of the controller, and the input of the controller is electrically connected to the contact sensor 54.

[0025] In this embodiment, when using the oral support exercise device after nasopharyngeal carcinoma radiotherapy, the upper dental tray 2 and lower dental tray 3 are placed in corresponding positions in the oral cavity. Air is pumped into the air bladder 13 via the air inlet 15 and the air supply tube 14. The inflated air bladder 13 expands the upper dental tray 2 and lower dental tray 3, allowing them to open and close. Simultaneously, the limiting rods 231 at both ends slide within the first groove 11 of the support ring 1, ensuring stable movement. When the upper dental tray 2 and lower dental tray 3 move, they drive the corresponding first sliding rod 232 and second sliding rod 234 to slide within the second groove 12. The pointer 233 at their ends indicates the mouth opening amplitude on the elliptical measuring ring 4, enabling intuitive measurement.

[0026] Before the upper teeth holder 2 and lower teeth holder 3 open, the adjusting slider 5 needs to be slid along the elliptical measuring ring 4 to move to the previous opening data of the upper teeth holder 2 and lower teeth holder 3. Then, a pair of locking blocks 51 will lock the elliptical measuring ring 4, and the limiting block 55 will slide within the limiting groove 41. When the end of the first sliding rod 232 engages the arc-shaped positioning groove 53, it will push the adjusting slider 5 to continue sliding along the elliptical measuring ring 4. Subsequently, the contact sensor 54 will be triggered, sending a signal to the controller. The controller receives the signal and sends a command to control the voice prompt 52 to announce that the current opening data of the upper teeth holder 2 and lower teeth holder 3 has improved compared to before, thus providing feedback on the exercise progress. If the contact sensor 54 is not triggered, the opening data of the upper teeth holder 2 and lower teeth holder 3 will not improve. When deflated, the airbag 13 contracts, and the device can be manually reset for convenient next use.

[0027] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
