Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of oral and maxillofacial muscle auxiliary training tools, specifically relating to an oral and maxillofacial muscle strength training device. Background Technology
[0002] Oral and maxillofacial muscle strengthening training is a method of improving oral function by training and strengthening the muscles of the oral and maxillofacial region. The main targets of this type of training include the masticatory muscles, tongue muscles, and facial expression muscles. Oral and maxillofacial muscle strengthening training is particularly important in the following situations: for some oral diseases, such as temporomandibular joint disorders (TMJ disorders), lingual disorders, masticatory muscle pain or dysfunction, oral and maxillofacial muscle strengthening training can help improve symptoms or restore function; for surgical rehabilitation of the oral and maxillofacial region, including after fracture, tumor removal, or orthodontic surgery, oral and maxillofacial muscle strengthening training helps restore normal chewing, swallowing, and speech functions; for orthodontic treatment, oral and maxillofacial muscle strengthening training can help improve the growth and development of the maxillofacial bones and help correct malocclusion; oral and maxillofacial muscle strengthening training is also an important part of speech therapy and pronunciation training.
[0003] Methods for improving oral and maxillofacial muscle strength include: deep pressure massage, where a therapist applies deep pressure to the oral and maxillofacial muscles while chewing or biting down. This direct pressure helps strengthen the muscles and improve their endurance; tapping massage, where the oral and maxillofacial muscles are tapped while chewing or biting down. This tapping helps stimulate the muscles, thereby improving their strength and function; stretching massage, where the oral and maxillofacial muscles are stretched while chewing or biting down. This stretching helps increase muscle flexibility, thus improving its function; and vibrating massage, where a vibrator is used to gently and slowly vibrate the masseter muscle. This vibration helps stimulate the muscles, thereby improving their strength and function.
[0004] However, current oral and maxillofacial muscle training devices on the market cannot simultaneously fulfill all four training functions, especially for tapping or stretching muscles when they are under tension to enhance training effectiveness. Furthermore, most existing oral and maxillofacial muscle training devices have other problems, such as the inability to provide timely feedback on training intensity data during training and the inability to adjust training intensity. These issues may negatively impact training results. Summary of the Invention
[0005] To address the problem that existing oral and maxillofacial muscle training devices cannot simultaneously provide multiple training functions, this invention provides an oral and maxillofacial muscle strength training device that achieves multifunctional and selectable training effects, especially by tapping or traction on the oral and maxillofacial muscles in a tense state to promote training effects.
[0006] The solution to the technical problem of this invention is as follows: An oral and maxillofacial muscle strength training device is used, comprising a base and an occlusal training component, which are fixed together. The occlusal training component includes an NF elastic plate, a flexible dental brace, and a pressure sensor. The NF elastic plate comprises two parallel elastic plates, whose posterior roots are fixed together by an arc segment. Flexible dental braces are fitted onto the front ends of the two elastic plates. A support plate is fixed to the front side of the base. A transverse sleeve is connected between the support plate and the root of the NF elastic plate. The transverse sleeve includes an outer sleeve and an inner sleeve that are nested together. A pressure sensor is installed inside the transverse sleeve. When the transverse sleeve is compressed, it compresses the pressure sensor, causing it to generate a pressure signal. The data line of the pressure sensor is connected to the signal input terminal of a host or controller. The host or controller outputs the pressure signal to a display to show the corresponding pressure data.
[0007] Preferably, the base includes a handle, a rear seat, and a front seat, wherein the front end of the handle is fixed to the rear seat, the rear seat and the front seat are fixed together by screws, and the inner cavity of the front seat includes two mounting slots located at the upper and lower parts for mounting the bite training components.
[0008] Preferably, the system further includes a force adjustment mechanism, which comprises an adjustment frame, a sliding sleeve, a vertical sleeve, and a second pressure sensor. The adjustment frame is a rectangular frame fitted onto the outside of the NF elastic plate, comprising left and right side plates and upper and lower top plates. The upper and lower sliding sleeves are respectively fitted onto the outer sides of the two elastic plates of the NF elastic plate and can slide freely. Each sliding sleeve has protruding pins on its left and right sides, and shaft holes are respectively provided in the upper and lower parts of the inner side of the adjustment frame, with each pin being assembled into the corresponding shaft hole. A vertical sleeve is connected between the upper and lower sliding sleeves, comprising an outer sleeve and an inner sleeve that fit together. The second pressure sensor is installed inside the vertical sleeve. When the vertical sleeve is compressed, it compresses the second pressure sensor, causing it to generate a pressure signal. The data line of the second pressure sensor is connected to the signal input terminal of the host or controller, and the host or controller outputs the pressure signal to the display to show the corresponding pressure data.
[0009] Sliding the adjustment frame forward or backward changes the position of the upper and lower sliding sleeves on the NF elastic plate. When the adjustment frame is in the rear position, the two elastic plates on the front of the NF elastic plate have a larger margin, resulting in lower bite resistance. When the adjustment frame is in the front position, the two elastic plates on the NF elastic plate have a smaller margin, resulting in higher bite resistance. By sliding the adjustment frame, the pressure resistance can be changed, thereby altering the training intensity.
[0010] Preferably, it further includes a striking drive mechanism, which includes a composite cover, a fixed base, a vibrating base, a swing arm, an auxiliary rod, an electromagnet, a guide rod, and a guide sleeve. The composite cover is fixed to the upper side of the rear seat, and a fixed base is fixed in the middle of the inner cavity of the composite cover. An electromagnet is fixedly installed on the front side of the fixed base. A through hole is provided in the middle of the front side of the fixed base, and a guide sleeve is installed thereon. A guide rod is fitted inside the guide sleeve, and a vibrating base is fixed to the inner end of the guide rod. A permanent magnet is embedded in the inner cavity of the vibrating base. Swing arms are hinged to the left and right sides of the fixed base via pins, and auxiliary rods are hinged to the left and right sides of the vibrating base via pins. The auxiliary rods are hinged to the swing arms via pins. Thus, when the electromagnet generates high-frequency changes in positive and negative magnetism, it can frequently attract and repel the permanent magnet. A striking module is installed at the end of the swing arm.
[0011] Preferably, it also includes an electric actuator, which is fixed at the rear end of the fixed base. The electric actuator has the electromagnet fixedly installed on its telescopic section. The electric actuator is controlled by a controller to change the position of the electromagnet, thereby changing the vibration position of the vibrating seat and thus changing the swing amplitude of the swing arm and the auxiliary rod.
[0012] Preferably, functional adjustment units are fitted at the ends of the left and right swing arms to improve the training function.
[0013] The function adjustment unit includes an angle rod, a striking unit, and / or a traction unit. An angle rod is hinged to the end of the swing arm via a pin, and a striking unit and / or a traction unit are installed at the end of the angle rod.
[0014] Preferably, the swing arm has a sleeve structure that allows for length adjustment.
[0015] The above-mentioned oral and maxillofacial muscle strength training device has the following beneficial effects: 1. Multifunctional: This training device can not only perform routine oral and maxillofacial muscle strength training, but also simultaneously perform percussion and traction training, enhancing the training effect.
[0016] 2. Real-time feedback: Pressure data is recorded and displayed through pressure sensors, allowing users to understand pressure changes in real time during training, which helps to better grasp the training intensity and effect.
[0017] 3. Adjustable: The elastic plate, sliding sleeve and other structures of the training equipment are adjustable, and the training intensity can be adjusted according to the user's needs and training stage.
[0018] 4. Tapping training: The electromagnetic drive structure allows the training device to tap the muscles of the oral and maxillofacial region at high frequency, which helps relieve muscle tension, improve blood circulation, and enhance training effects.
[0019] 5. Traction training: This training device can also perform suction traction training through a suction bowl to further enhance the training effect.
[0020] 6. Flexible use: The function adjustment unit allows the training equipment to perform tapping or suction traction training according to the user's needs, making it more flexible to use.
[0021] 7. Safety: Various safety measures in the design, such as preventing excessive stretching or compression, make the user safer during use.
[0022] 8. Angle Adjustment: The angle adjustment mechanism between the swing arm and the angle bar allows for adjustment of the striking or traction angle according to training needs, enhancing training effectiveness and comfort.
[0023] 9. Personalized Training: By changing the training intensity, users can conduct personalized training according to their own needs, improving training effectiveness and satisfaction. Attached Figure Description

Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] An oral and maxillofacial muscle strength training device is proposed to improve upon the existing oral and maxillofacial muscle training devices, which cannot simultaneously perform multiple training functions and cannot tap or pull the oral and maxillofacial muscles in a tense state to promote the training effect. The training device mainly includes a base 1, an occlusion training component 2, a force adjustment mechanism 3, a tapping drive mechanism 4, and a function adjustment unit 5.
[0028] Specifically, such as Figure 1 and Figure 4 As shown, the base 1 includes a handle 11, a rear seat 12, and a front seat 13. The front end of the handle 11 is fixed to the rear seat 12, and the rear seat 12 and the front seat 13 are fixed together by screws. The inner cavity of the front seat 13 includes two mounting slots 14 located at the upper and lower parts for mounting the bite training component 2. The separate design of the rear seat 12 and the front seat 13 facilitates the mounting of the bite training component 2.
[0029] like Figure 6As shown, the bite training component 2 includes an NF elastic plate 21, a flexible dental brace 22, a support plate 23, a transverse sleeve 24, and a pressure sensor 25. The NF elastic plate 21 comprises two parallel elastic plates, their rear roots fixed together by an arc segment. The front ends of the two elastic plates are respectively fitted with flexible dental braces 22. A support plate 23 is fixed to the front side of the front seat 13. A transverse sleeve 24 connects the support plate 23 and the root of the NF elastic plate 21. The transverse sleeve 24 includes an outer sleeve and an inner sleeve that fit together. A pressure sensor 25 is installed inside the transverse sleeve 24. When the transverse sleeve 24 is compressed (pulling the handle outward during training will cause the transverse sleeve 24 to generate inward pressure), it will compress the pressure sensor 25, causing it to generate a pressure signal. The data line of the pressure sensor 25 is connected to the signal input terminal of the host (or controller), and the host outputs the pressure signal to the display to show the corresponding pressure data.
[0030] like Figure 4 and Figure 6 As shown, the force adjustment mechanism 3 includes an adjustment frame 31, sliding sleeves 32, a vertical sleeve 34, and a pressure sensor 35. The adjustment frame 31 is a rectangular frame fitted onto the outside of the NF elastic plate 21, including left and right side plates and upper and lower top plates. The upper and lower sliding sleeves 32 are respectively fitted onto the outer sides of the two elastic plates of the NF elastic plate 21 and can slide freely. Each sliding sleeve 32 has protruding pins 33 on its left and right sides, and shaft holes are respectively provided in the upper and lower parts of the inner side of the adjustment frame 31, with each pin 33 being assembled into its corresponding shaft hole. A vertical sleeve 34 connects the upper and lower sliding sleeves. The vertical sleeve 34 includes an outer sleeve and an inner sleeve that fit together. The pressure sensor 35 is installed inside the vertical sleeve 34. When the vertical sleeve 34 is compressed (during training, the teeth bite down on the upper and lower braces, which causes the vertical sleeve 34 to exert inward pressure), it will compress the pressure sensor 35, giving it a pressure signal. The data line of the pressure sensor 35 is connected to the signal input terminal of the host (or controller), and the host outputs the pressure signal to the display to show the corresponding pressure data.
[0031] Sliding the adjustment frame 31 forward or backward changes the position of the upper and lower sliding sleeve 32 on the NF elastic plate 21. When the adjustment frame 31 is in the rear position, the two elastic plates on the front side of the NF elastic plate 21 have a larger margin, resulting in lower biting resistance. When the adjustment frame 31 is in the front position, the two elastic plates on the NF elastic plate 21 have a smaller margin, resulting in higher biting resistance. By sliding the adjustment frame 31, the pressure resistance can be changed, thereby altering the training intensity.
[0032] like Figures 1-3As shown, the striking drive mechanism 4 includes a composite cover 41, a fixed base 42, an electric actuator 43, a vibrating base 44, a swing arm 45, an auxiliary rod 46, an electromagnet 47, a guide rod 48, and a guide sleeve 49. The composite cover 41 is fixed to the upper side of the rear seat 12. The fixed base 42 is fixed in the middle of the inner cavity of the composite cover. The electric actuator 43 is fixed to the rear end of the fixed base 42, and the electromagnet 47 is fixedly installed on the telescopic section of the electric actuator 43. A through hole is provided in the middle of the front side of the fixed base 42, and a guide sleeve 49 is installed thereon. The guide rod 48 is fitted inside the guide sleeve 49. The vibrating base 44 is fixed to the inner end of the guide rod 48. A permanent magnet is embedded in the inner cavity of the vibrating base 44. The left and right sides of the fixed base 42 are respectively hinged to the swing arms 45 by pins. The left and right sides of the vibrating base 44 are respectively hinged to the auxiliary rods 46 by pins. The auxiliary rods 46 on both sides are respectively hinged to the swing arms 45 on both sides by pins. Therefore, when the electromagnet 47 generates high-frequency changes in positive and negative magnetism (by changing the direction of the current), it can frequently attract and repel the permanent magnet. When the two are attracted, the auxiliary rod 46 will push the swing arm 45 outward to unfold; when they are repelled, the auxiliary rod 46 will pull the swing arm 45 inward to retract. A striking module is installed at the end of the swing arm 45, so that the unfolding and retraction of the swing arm can drive the striking module to perform high-frequency striking on the oral and maxillofacial muscles. This striking is accompanied by biting force and traction force, which can relieve tension in the oral and maxillofacial muscles and promote blood circulation. The swing arm 45 has a sleeve structure that allows for length adjustment.
[0033] The aforementioned electric actuator 43, controlled by a controller, can change the position of the electromagnet 47, thereby altering the vibration position of the vibrating seat 44 and consequently changing the swing amplitude of the swing arm 45 and the auxiliary rod 46. This modification allows for adjustments during training to change the striking amplitude and thus the striking intensity.
[0034] Furthermore, functional adjustment units 5 are fitted to the ends of the left and right swing arms 45 to enhance the training function. One form of functional adjustment unit 5 is as follows: Figure 1 and Figure 7 As shown, it mainly includes an angle rod 51, a second pin 52, a first fork 53, a flexible hammer 54, a second fork 55, and a suction cup 56.
[0035] An angle rod 51 is hinged to the end of the swing arm 45 via a pin 52. A first fork 53 and a second fork 55 are rotatably connected (in a fitted relationship, such as a rotating sleeve or rod) at the end of the angle rod 51. A flexible hammer 54 is installed at the end of the first fork 53, and a suction cup 56 is installed at the end of the second fork 55. When the two forks are flipped, the flexible hammer 54 can be used to tap the maxillofacial muscles on both sides of the mouth, or the suction cup 56 can be used to suction and pull the maxillofacial muscles on both sides of the mouth. Preferably, the angle rod 51 is designed as a sleeve structure that allows for adjustment of length, rotation angle, and locking, for example, by means of a locking wire.
[0036] Preferably, the suction bowl 56 employs a negative pressure suction method. For example, an air tube 57 is installed inside each rod cavity, with one end of the air tube 57 connected to the suction bowl 56 and the other end connected to the negative pressure system. When the suction bowl function is selected, rotating the second fork activates the solenoid valve of the negative pressure system. For example, a contact switch is installed inside the rotating connection structure (rotating sleeve or rotating rod). When the second fork 55 carries the suction bowl 56 closer to the face, the contact switch is triggered, and the trigger signal is transmitted to the main unit (or controller), which further controls the opening and closing of the suction tube solenoid valve of the negative pressure system. The opening and closing frequency is synchronized with the electromagnet commutation frequency, generating a periodic negative pressure suction and air cut-off function.
[0037] Furthermore, an angle adjustment mechanism is provided between the swing arm 45 and the angle rod 51 to change their angle. For example, supports 58 are fixed at the base of the swing arm 45 and the angle rod 51 respectively, and a telescopic adjustment member 59 is hinged between the two supports. Figure 7 The telescopic adjustment element 59 shown includes two screws at both ends and a screw sleeve in the middle. The two screws are in opposite directions, and rotating the screw sleeve can drive the two screws at both ends to move inward or outward.
[0038] The above-mentioned oral and maxillofacial muscle strengthening device has multiple functions and can monitor and adjust pressure. The following are its usage instructions: First, ensure that all components are installed correctly. This includes ensuring that all screws are tightened and that each component is in its proper place.
[0039] For the bite training component, the user needs to place their teeth on the flexible braces. The user can adjust the bite resistance by changing the position of the elastic plate using the adjustment frame. When the adjustment frame is further back, the bite resistance is lower; when the adjustment frame is further forward, the bite resistance is higher.
[0040] When a user bites down on the braces, the vertical sleeves are compressed, and a pressure sensor generates a signal indicating the pressure the user is applying. This helps the user monitor and adjust the intensity of their training.
[0041] For the striking mechanism, the user needs to grip the handle and pull it outwards, which causes pressure to be applied inwards to the transverse sleeve. Simultaneously, a pressure sensor generates a signal, which is then converted into displayed pressure data.
[0042] The electric actuator generates high-frequency positive and negative magnetic changes, which cause the swing arm to rapidly extend and retract. At the end of the swing arm is a striking module that delivers high-frequency tapping to the maxillofacial muscles. This tapping, accompanied by biting force and traction, helps relieve tension in the maxillofacial muscles and promotes blood circulation.
[0043] Users can also enhance training capabilities using the function adjustment unit. Users can choose to use a flexible hammer for tapping or a suction cup for suction and traction. When the user selects to use the suction cup, the negative pressure system will activate, generating periodic suction and desiccation.
[0044] By adjusting the angle between the swing arm and the angle bar, users can change the angle of tapping or suction traction. This training device offers many useful functions for oral and maxillofacial muscle strength training. However, before starting to use it, please ensure that the user fully understands how to operate the device and makes adjustments as needed. If the user has any questions or confusion, please seek help from a professional medical person.
[0045] The specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
