Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically a training and testing device for assessing chewing function. Background Technology
[0002] With the development of modern stomatology, people are paying increasing attention to the assessment of chewing function. Chewing function not only relates to an individual's oral health but also affects overall nutrient intake and digestive system function. Therefore, developing accurate and reliable chewing function assessment equipment is of great significance. Traditional chewing function assessment involves patients chewing two-color gum a limited number of times, and assessors score the patient's chewing ability based on the color mixing of the gum after chewing. This method not only requires temporary material preparation but also consumes considerable manpower, and the subjective observation of the gum color mixing also affects the accuracy of the final chewing ability assessment.
[0003] Based on this, using chewing gum of moderate hardness for chewing ability recovery exercises is also cost-effective. No more than 3 times a day, with each chewing session lasting no more than 15 minutes, will be beneficial for chewing ability training and recovery. However, existing devices do not have the function of scientifically planning and standardizing the testing process of chewing ability training and testing with chewing gum. Therefore, it is necessary to propose an exercise testing device for chewing function assessment that can perform standardized mechanical testing of patients' chewing ability using chewing gum, scientifically plan chewing exercises with chewing gum, and facilitate the testing of recovery status. Utility Model Content
[0004] To address the aforementioned issues, the purpose of this invention is to provide an exercise testing device for assessing chewing function. This device can mechanically detect the degree of color mixing in two-color chewing gum, store the gum so that patients can exercise their chewing ability at home at any time, and simultaneously detect the texture data such as the hardness of the chewing gum after exercise to monitor the recovery of chewing ability.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A training and testing device for assessing chewing function includes a housing. A partition inside the housing divides the housing into an upper storage chamber and a testing chamber, and a lower waste chamber. A dispensing assembly is fixedly connected to the storage chamber. The dispensing assembly includes an arc-shaped plate. The outer periphery of the arc-shaped plate is fixedly connected to the bottom wall of the storage chamber. A base plate is fixedly connected to the cross-section of the arc-shaped plate near the partition. Several sub-plates are vertically fixedly connected to the inner periphery of the arc-shaped plate, and each sub-plate is vertically fixedly connected to the base plate. Several circumferentially oriented springs are hinged to the center of the base plate near the arc-shaped plate. Chewing gum is pressed between the elastic sheet and the curved plate. The part of the base plate near the curved plate has an arc-shaped through groove parallel to the curved plate. A servo motor is fixedly connected to the side of the base plate near the partition. The output shaft of the servo motor faces the partition and is fixedly connected to an eccentric block. The eccentric block slides with the partition. A first electric push rod is fixedly connected to the outer periphery of the side of the eccentric block near the servo motor. The output part of the first electric push rod faces the base plate and is fixedly connected to a pushing arc plate. The thickness of the pushing arc plate is less than that of the arc-shaped through groove. The test chamber is equipped with a test component for testing the color mixing and hardness changes of the chewing gum.
[0006] The basic principle of the solution is: by distributing components to store and push the required chewing gum, patients can take the chewing gum at any time for exercise and testing. After chewing, the chewing gum is photographed by the testing components for color and texture detection, which reduces the uncertainty of manual testing, improves accuracy, and allows the progress of chewing ability to be tracked after each exercise, thus reducing manpower consumption.
[0007] The beneficial effects of the basic solution are: 1. The device integrates the storage, dispensing, and testing functions of chewing gum, forming a complete assessment system. Patients do not need to prepare additional chewing gum or search for testing tools; they can complete the entire chewing function assessment process using only this one device, greatly improving ease of use.
[0008] 2. The automatic dispensing of chewing gum is achieved through the cooperation of a servo motor and a first electric push rod. This mechanized operation not only reduces manual intervention, but the testing components can also accurately measure the color mixing and hardness changes of chewing gum, providing doctors with objective and quantitative assessment data, which helps to more accurately judge the recovery of the patient's chewing function.
[0009] 3. The separate design of the storage and testing rooms, as well as the designated waste disposal room, ensures the hygiene and safety of chewing gum during storage, distribution, and testing. Used chewing gum can be promptly disposed of in the waste disposal room, preventing cross-contamination and bacterial growth.
[0010] Furthermore, a dust cover is provided on the side wall of the storage chamber away from the partition. The dust cover is hinged to the top wall of the storage chamber, and an arc-shaped opening is opened on the side wall of the dust cover, which corresponds to an arc-shaped groove.
[0011] The benefits of the basic solution are: 1. The dust cover effectively prevents external dust and debris from entering the storage room, maintaining a clean environment. This is crucial for stored chewing gum, preventing contamination and ensuring its hygiene and safety.
[0012] 2. The dust cover is hinged to the top wall of the storage compartment, making it very convenient to open and close. Users can open or close the dust cover with a simple push or pull, without any additional steps or tools required to replenish the chewing gum.
[0013] 3. The arc-shaped opening on the side wall of the dust cover corresponds to the arc-shaped slot in the storage chamber. This design ensures that the chewing gum can pass smoothly during dispensing. When the servo motor and the first electric push rod work together, the chewing gum is pushed to the arc-shaped slot and smoothly extends out of the arc-shaped opening for the user to use. This corresponding design improves the dispensing efficiency of the chewing gum and reduces jamming or failures during the dispensing process.
[0014] 4. The dust cover design also helps maintain a stable internal environment in the storage room. When the dust cover is closed, it effectively blocks external environmental factors such as temperature and humidity from affecting the storage environment, ensuring that the chewing gum will not deteriorate or be damaged due to environmental factors during storage.
[0015] Furthermore, a display controller is fixedly connected to the top wall of the storage chamber. The output of the display controller is connected to the input of the servo motor and the first electric push rod. The display controller is used to preset exercise parameters and calculate and display test results.
[0016] The beneficial effects of the basic solution are: 1. The introduction of the display controller makes the entire device more integrated. Users can complete all operations through the display controller, including preset exercise parameters, starting and stopping tests, etc. The movements of the servo motor and the first electric push rod are completely controlled by the display controller, realizing automated operation. This reduces manual intervention and improves the operating efficiency and accuracy of the equipment.
[0017] 2. The display controller can calculate and display test results in real time, such as the degree of color mixing and hardness changes of chewing gum. These results are presented to the user in an intuitive way, making it easy for the user to quickly understand the patient's chewing function recovery. Patients can adjust exercise parameters or develop a more scientific rehabilitation plan based on the test results, thereby improving the accuracy and effectiveness of the assessment.
[0018] 3. The display controller can also record the results and data of each test, facilitating user tracking and analysis. This data can be used to assess the patient's chewing function recovery and provide important reference for subsequent treatment and rehabilitation plans.
[0019] Furthermore, the width of the push arc plate is smaller than the distance between adjacent plates.
[0020] The beneficial effects of the basic solution are: 1. When the width of the pusher arc is less than the distance between adjacent plates, the pusher arc will not interfere with the plates during movement. This ensures that the chewing gum can pass smoothly through the arc-shaped channel during dispensing without getting stuck or damaged.
[0021] 2. The precise design of the pusher arc length helps ensure accurate quantity and consistent placement of chewing gum each time. This contributes to improved test accuracy and repeatability, making the evaluation results more reliable.
[0022] Furthermore, the number of sub-plates must be at least 7.
[0023] The basic solution offers the advantage that seven or more dispensing plates can hold and dispense different types of chewing gum. This enhances the adaptability and flexibility of the device, enabling it to meet the diverse needs of patients and testing.
[0024] Furthermore, the chewing gum includes test gum and exercise gum, with the exercise gum including five different hardness levels, and all chewing gums are two-color plate-shaped gums.
[0025] The beneficial effects of the basic program are: 1. The design of the two-color plate gum allows for observation of the color mixing after testing, thereby assessing the patient's chewing strength and mixing ability. The five different hardness levels of the exercise gum can simulate foods of varying hardness, helping patients gradually adapt to and restore their chewing function, achieving a gradual, restorative transition from soft to hard.
[0026] 2. Based on the patient's specific condition, doctors can develop a personalized exercise plan and choose an appropriate gum hardness to achieve the best training effect. The variety of gum hardness options makes the exercise more targeted and effective, helping patients recover their chewing function more quickly.
[0027] 3. The design of the two-color plate-shaped chewing gum makes the test results more intuitive and easier to observe, helping doctors to more accurately assess the recovery of the patient's chewing function.
[0028] 4. Five different hardness levels of chewing gum provide patients with more choices and challenges, helping to enhance their participation and motivation. Chewing gum itself is also a pleasurable experience, which can reduce patients' stress and anxiety, and improve the comfort of the recovery process.
[0029] 5. Chewing gum helps promote saliva production, effectively relieving dry mouth and bad breath. Some ingredients in chewing gum can also reduce the number of cariogenic bacteria and plaque in the mouth, lowering the risk of gingivitis.
[0030] Furthermore, the testing components include a diffuse reflector plate fixedly connected to the bottom wall of the testing chamber, an input port corresponding to the diffuse reflector plate on the top wall of the testing chamber, cameras fixedly connected to the inner walls of the testing chamber on both sides of the input port, each camera fixedly connected to a supplementary light and facing the diffuse reflector plate, the diffuse reflector plate is used to reduce the influence of specular reflection on the camera shooting results, a texture analyzer fixedly connected to the bottom wall of the testing chamber near the partition, the texture analyzer is used to detect the texture data of chewed gum after chewing, a second electric push rod fixedly connected to the bottom wall of the testing chamber away from the partition, the output of the second electric push rod fixedly connected to a push plate and facing the diffuse reflector plate, a disposal port leading to the waste chamber on the bottom wall of the testing chamber near the partition, the input ends of the supplementary light and the second electric push rod are both connected to the output signal of the display controller, and the output ends of the camera and the texture analyzer are both connected to the input signal of the display controller.
[0031] The beneficial effects of the basic design are: 1. The diffuse reflector design effectively reduces the impact of specular reflection on the camera's image, resulting in clearer and more realistic images of the chewing gum. This helps doctors more accurately assess the patient's chewing behavior, improving the accuracy and reliability of the test.
[0032] 2. The introduction of a texture analyzer allows for precise measurement of the texture data of chewed gum, such as hardness, elasticity, and stickiness. This data is crucial for assessing a patient's chewing force and efficiency, and helps doctors develop more scientific rehabilitation plans.
[0033] 3. The design of the second electric pusher allows chewed gum to be automatically pushed into the waste chamber, avoiding the tediousness and inconvenience of manual cleaning. At the same time, the design of the waste chamber's disposal opening facilitates centralized processing and management of waste, improving the hygiene and efficiency of the equipment.
[0034] Furthermore, the texture analyzer includes a pressure test plate, which is fixedly connected to the bottom wall of the test chamber. A pressure test pusher is fixedly connected to the top wall of the test chamber corresponding to the pressure test plate, and a gel probe is provided at the bottom of the pressure test pusher.
[0035] The benefits of the basic approach are: 1. The texture analyzer, through the combination of a pressure testing plate and a gel probe, can accurately measure the texture data of chewing gum after chewing, such as hardness, elasticity, and stickiness. These texture properties are important indicators for assessing the recovery of chewing function, helping doctors to more accurately understand the patient's chewing ability.
[0036] 2. The pressure test pusher controls the pressure applied to the chewing gum by the gel probe, ensuring consistent testing conditions for each test. This reduces errors during the testing process and improves the accuracy and reliability of the test.
[0037] 3. The texture analyzer is connected to the display controller, enabling automated testing. Doctors only need to preset the test parameters, and the texture analyzer can automatically complete the test and record the data, improving testing efficiency.
[0038] Furthermore, the waste compartment is equipped with a waste container for holding discarded chewing gum.
[0039] The beneficial effects of the basic solution are: 1. The introduction of the waste container provides a dedicated collection container for discarded chewing gum, preventing it from being randomly discarded or scattered in the testing room, thus maintaining the cleanliness and hygiene of the testing environment. This is of great significance in preventing bacterial growth and reducing the risk of cross-infection.
[0040] 2. The waste container design makes cleaning up used chewing gum simpler and more convenient. After the test, simply remove the waste container and empty its contents to complete the cleaning. This reduces the tediousness and inconvenience of manual cleaning and improves the efficiency of the testing operation.
[0041] Furthermore, the inlet is equipped with a dustproof plate with openings facing both sides laterally.
[0042] The beneficial effects of the basic solution are: 1. Dustproof panels can protect the testing equipment. Long-term exposure to the external environment makes testing equipment susceptible to adverse factors such as dust and moisture, leading to performance degradation or damage. The installation of dustproof panels can reduce the corrosive effects of these factors on the equipment, extending its service life.
[0043] 2. The dustproof design makes the testing process cleaner and more organized. Users are not disturbed by dust or other contaminants during testing, improving comfort and convenience. At the same time, the dustproof panel also enhances the aesthetics of the test components, improving the overall user experience. Attached Figure Description

[0049] Example
[0050] The basics are as follows: Figure 1 , Figure 2 and Figure 3 As shown: A training and testing device for assessing chewing function includes a housing 1. A partition 2 divides the housing 1 into an upper storage chamber and a testing chamber, and a lower waste chamber. A dispensing assembly is fixedly connected to the storage chamber. The dispensing assembly includes an arc-shaped plate 19. The outer periphery of the arc-shaped plate 19 is fixedly connected to the bottom wall of the storage chamber. A base plate 18 is fixedly connected to the cross-section of the arc-shaped plate 19 near the partition 2. Several sub-plates 20 are vertically fixedly connected to the inner periphery of the arc-shaped plate 19, and each sub-plate 20 is vertically fixedly connected to the base plate 18. The number of sub-plates 20 is at least seven. A torsion spring 21 is hinged to a number of circumferential elastic plates 24 on the central side of the base plate 18 near the arc-shaped plate 19. Chewing gum 25 is pressed between the elastic plates 24 and the arc-shaped plate 19. The portion of the base plate 18 near the arc-shaped plate 19 has an opening flush with the arc-shaped plate 19. The arc-shaped through groove 26 is arranged in a row. A servo motor 17 is fixedly connected to the side of the bottom plate 18 near the partition 2. The output shaft of the servo motor 17 faces the partition 2 and is fixedly connected to an eccentric block 14. The eccentric block 14 slides with the partition 2. A first electric push rod 15 is fixedly connected to the outer periphery of the side of the eccentric block 14 near the servo motor 17. The output part of the first electric push rod 15 faces the bottom plate 18 and is fixedly connected to a pushing arc plate 27. The thickness of the pushing arc plate 27 is less than that of the arc-shaped through groove 26. A dust cover 22 is provided on the side wall of the storage chamber away from the partition 2. The dust cover 22 is hinged to the top wall of the storage chamber. An arc-shaped through opening 23 is opened on the side wall of the dust cover 22. The arc-shaped through opening 23 corresponds to the arc-shaped through groove 26. The width of the pushing arc plate 27 is less than the distance between adjacent partition plates 20. A waste cylinder 3 for holding waste chewing gum 25 is provided in the waste chamber.
[0051] Chewing gum 25 includes test gum and exercise gum. The exercise gum includes five different hardness levels. All chewing gum 25 are two-color plate-shaped gums.
[0052] A display controller 16 is fixedly connected to the top wall of the storage chamber. The output of the display controller 16 is connected to the input of the servo motor 17 and the first electric push rod 15. The display controller 16 is used to preset exercise parameters and calculate and display test results.
[0053] The testing chamber is equipped with a testing assembly for testing the color mixing and hardness changes of chewing gum 25. The testing assembly includes a diffuse reflector plate 6 fixedly connected to the bottom wall of the testing chamber. An input port 11 corresponding to the diffuse reflector plate 6 is opened in the top wall of the testing chamber. Cameras 9 are fixedly connected to the inner walls of the testing chamber on both sides of the input port 11. Each camera 9 is fixedly connected to a supplementary light 10 and faces the diffuse reflector plate 6. The diffuse reflector plate 6 is used to reduce the influence of specular reflection on the image captured by the camera 9. A texture analyzer is fixedly connected to the bottom wall of the testing chamber on the side closest to the partition 2. The texture analyzer is used to detect the texture data of the chewing gum 25 after chewing. A second electric push rod 7 is fixedly connected to the bottom wall of the testing chamber on the side away from the partition 2. The output of the push rod 7 is fixedly connected to a push plate and faces the diffuse reflector plate 6. The bottom wall of the test chamber near the partition 2 has a disposal port 4 leading to the waste chamber. The input ends of the supplementary light 10 and the second electric push rod 7 are both connected to the output end of the display controller 16. The output ends of the camera 9 and the texture analyzer are both connected to the input end of the display controller 16. The texture analyzer includes a pressure test plate 5, which is fixedly connected to the bottom wall of the test chamber. A pressure test pusher 13 is fixedly connected to the top wall of the test chamber corresponding to the pressure test plate 5. A gel probe 8 is fixedly connected to the bottom end of the pressure test pusher 13. The inlet 11 is provided with a dustproof plate 12 with openings facing the horizontal sides. The preferred model of the texture analyzer is CTA-20HD.
[0054] The specific implementation process is as follows: Six different types of chewing gum 25 are stored between the elastic sheet 24 and the arc plate 19. The chewing gum 25 is separated by partition plates 20. Seven partition plates 20 are required for the six types of chewing gum 25. The partition plates 20 provide support for the positioning and pushing of the chewing gum 25 on the arc plate 19. The patient can preset the test items and exercise items on the control display. For example, in the test items, the display controller 16 controls the servo motor 17 to rotate the eccentric block 14 so that the pushing arc plate 27 fixed on the first electric push rod 15 is aligned with the test chewing gum. And stabilized, the first electric push rod 15 is started, and the partition 2 provides support for the first electric push rod 15. The pusher 27 passes through the arc-shaped through groove 26 on the base plate 18 and pushes the piece of test chewing gum closest to the arc plate 19 out of the pressing range of the elastic piece 24 between the two partition plates 20, but does not completely detach it from the arc plate 19. A small part of the pushed-out test chewing gum is pressed on the arc plate 19, and most of the test chewing gum extends out of the arc-shaped through opening 23 on the dust cover 22. The patient can directly take it out and open it to start chewing. The servo motor 17 is preferably SRM005A40003.
[0055] The display controller 16 will provide visual prompts to chew the gum twenty times. The chewed gum is then dropped into the test chamber through the inlet 11 and falls onto the diffuser plate 6. The display controller 16 will then start the test. First, the cameras 9 on both sides of the inlet 11 will capture images of the gum illuminated by the supplementary lights 10. The gum images will be analyzed and color-coded in the display controller 16 to assess the degree of color mixing. A score will be given based on the human assessment. Because mechanical shooting and analysis are used, the subjective judgment of the evaluator will be avoided from affecting the accuracy of the results. The display controller 16 is preferably YXK-101, and the camera 9 is preferably Haique DZ013K.
[0056] After being photographed, the chewing gum is moved from the diffuse reflector plate 6 to the pressure test plate 5 of the texture analyzer by the second electric push rod 7. The pressure test pusher 13 above the pressure test plate 5 pushes the bottom gel probe 8 down at a preset speed, approaching the pressure test plate 5. During the downward pressure, the gel probe 8 and the pressure test plate 5 detect the force generated by the downward pressure of the probe on the chewing gum. The change in force reflects the hardness of the sample. After the hardness test target is reached, the gel probe 8 remains in contact with the chewing gum for 2 seconds. Then, the probe is quickly lifted back by the pressure test pusher 13. The resistance of the chewing gum to the return motion of the probe reflects the stickiness of the chewing gum at this time. Based on the change in force during the contact between the probe and the sample, the texture data of the chewing gum can be obtained. This texture data is displayed by the display controller 16 to show the chewing ability test results.
[0057] After the test is completed, the second electric push rod 7 pushes the chewing gum on the pressure test plate 5 through the disposal port 4 into the waste cylinder 3 in the waste chamber to reduce environmental pollution. The first electric push rod 15 and the second electric push rod 7 are preferably TiMOTION JP6.
[0058] In the exercise program, the display controller 16 first selects an exercise gum of appropriate hardness for the patient based on the patient's chewing ability test score and results. The exercise process is similar to the test program, except that the patient needs to chew the exercise gum continuously for 5 minutes. After chewing, the color mixing and texture data of the exercise gum are also detected. Since the hardness, chewing performance, and stickiness of the chewing gum will gradually decrease until the plateau period after a period of chewing, the display controller 16 can judge the progress and changes of the patient's chewing function in the exercise program based on the texture data of the exercise gum after chewing. This allows the controller to increase the hardness of the exercise gum or record the patient's chewing function recovery curve, providing a more scientific reference and helping the patient to accelerate the recovery of chewing function.
