Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multifunctional oral motor training device. Background Technology

[0002] Nasopharyngeal carcinoma is an epithelial malignant tumor originating from the nasopharyngeal mucosa, mainly occurring in the roof and lateral walls of the nasopharynx, especially the pharyngeal recess. Because the nasopharynx is anatomically located on the same plane as important structures such as the temporomandibular joint and masticatory muscles, radiotherapy inevitably affects the temporomandibular joint and masticatory muscles, causing degenerative changes and fibrosis, muscle atrophy, and joint stiffness, leading to temporomandibular joint dysfunction, i.e., difficulty opening the mouth. Oral muscle training is needed for prevention and rehabilitation. Oral muscle training includes mouth opening training, cheek puffing training, tongue muscle training, and neck rotation training. However, existing training devices only target one of these, and patients need to switch between multiple devices to complete the entire training. Therefore, a multifunctional oral muscle training device is needed, which allows patients to perform multiple training exercises using only one device. Summary of the Invention

[0007] The cheek-puffing training component includes a second airbag fixedly mounted on the upper pressure plate, a third airbag fixedly mounted on the upper pressure plate, a first one-way valve symmetrically fixed on both sides of the second airbag, and a second one-way valve symmetrically fixed on both sides of the third airbag; the second airbag, the third airbag, the first one-way valve, and the second one-way valve are mounted on the lower pressure plate in the same manner.

[0008] The tongue muscle training component includes a placement slot fixed on the lower pressure plate, a bracket rotatably mounted on the lower pressure plate, a tongue plate rotatably mounted on the bracket, a linkage device fixed on the base, and a reversing device fixed on the base and the lower pressure plate.

[0009] Specifically, the adjustment mechanism includes a third slide groove fixedly mounted on the base, a support rod slidably mounted on the third slide groove, a fourth slide groove fixedly mounted on the base, an adjustment seat rotatably mounted on the fourth slide groove, and a fifth slide groove fixedly mounted on the base.

[0010] Specifically, the drive mechanism includes a motor fixedly mounted on the base, an output shaft fixedly mounted on the motor, a pneumatic assembly fixedly mounted on the base and the output shaft, a reduction gearbox fixedly mounted on the output shaft, and a first gear fixedly mounted on the reduction gearbox; the first gear meshes with a gear ring.

[0011] Specifically, the pressure relief device includes a valve body fixedly mounted on the first airbag and the base, a sixth slide groove fixedly mounted on the valve body, a pressure relief cover slidably mounted on the sixth slide groove, and a first rack slidably mounted on the sixth slide groove; the first rack and the valve body are connected by a first spring; the pressure relief cover and the valve body are connected by a second spring.

[0012] Specifically, the linkage device includes a seventh slide groove fixed on the base, a second rack fixed on the upper pressure plate, a third rack slidably mounted on the seventh slide groove, a second gear rotatably mounted on the seventh slide groove, and a pressure roller fixed on the third rack; the second gear meshes with the second rack and the third rack on both sides respectively.

[0013] Specifically, the reversing device includes a second cavity fixedly mounted on the lower pressure plate, a baffle fixedly mounted on the bracket, metal contacts symmetrically fixedly mounted on the second cavity, and a vent valve fixedly mounted on the lower pressure plate; the second cavity and the valve body are connected by a second flexible hose; the baffle and the lower pressure plate are connected by a third spring.

[0015] The beneficial effects of this invention are:

[0016] (1) Integrating mouth opening training, cheek puffing training, tongue muscle training and neck turning training into one device, patients can perform all training by using only one device.

[0017] (2) It is more energy-efficient because it is driven by only one motor.

[0018] (3) Existing mouth-opening training devices simply fix the mouth in an open state, which can easily cause pain and fatigue for patients during training. When using the present invention for mouth-opening training, the upper pressure plate can slide up and down in the first cavity, causing the patient's mouth to open and close repeatedly, simulating the oral state when speaking and eating, so that the patient is less likely to feel fatigue and pain, and at the same time, the training effect can be improved.

[0019] (4) The tooth surface lengths on the first rack in the pressure relief device are different. Compared with racks with the same tooth surface length, the pressure relief cover has greater resistance when moving downward. That is, the air pressure in the first airbag needs to be greater to open the pressure relief cover. In other words, the upper pressure plate moves a longer distance upward, which allows the patient's mouth to open to the maximum extent and the training effect is better. Attached Figure Description

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1-8As shown, the multifunctional oral muscle training device of the present invention includes a base 1, an adjustment mechanism 2 fixedly mounted on the base, a training mechanism 3 rotatably mounted on the adjustment mechanism, and a drive mechanism 4 fixedly mounted on the base. The training mechanism includes a base 31 rotatably mounted on the adjustment mechanism, a neck rotation training component 32 fixedly mounted on the base and the base, a first cavity 33 fixedly mounted on the base, a mouth opening training component 34 slidably mounted on the first cavity, a cheek puffing training component 35 fixedly mounted on the mouth opening training component, and a tongue muscle training component 36 fixedly mounted on the base. The base is placed on a table. The adjustment mechanism is used to adjust the height of the base to accommodate patients of different heights. The training mechanism is used for oral muscle training. The drive mechanism is used to drive the training mechanism.

[0037] The neck rotation training component includes a first slide groove 321 fixedly mounted on the base, a toothed ring 322 rotatably mounted on the first slide groove, a connecting rod 323 fixedly mounted on the base and the toothed ring, and a second slide groove 324 fixedly mounted on the base. The toothed ring can rotate on the first slide groove. The second slide groove is used for limiting the rotation angle of the base. The rotation of the toothed ring drives the connecting rod and the base to rotate, that is, drives the patient's head to rotate, thus performing neck rotation training.

[0038] The mouth-opening training component includes an upper pressure plate 341 slidably disposed on the first cavity, a first airbag 342 fixedly disposed on the first cavity, a lower pressure plate 343 fixedly disposed on the base, and a pressure relief device 344 fixedly disposed on the base. The upper pressure plate can slide on the first cavity and is provided with a limiting post that penetrates the base to prevent the upper pressure plate from tilting during sliding. The first airbag is used to drive the upper pressure plate to move. The lower pressure plate is fixedly disposed on the base. The pressure relief device is used to depressurize the first airbag and drive the tongue muscle training device to work, achieving a linkage effect. The expansion of the first airbag causes the upper pressure plate to slide, opening the patient's mouth for mouth-opening training.

[0039] The cheek-puffing training component includes a second airbag 351 fixedly mounted on the upper pressure plate, a third airbag 352 fixedly mounted on the upper pressure plate, a first one-way valve 353 symmetrically fixed on both sides of the second airbag, and a second one-way valve 354 symmetrically fixed on both sides of the third airbag. The second airbag, the third airbag, the first one-way valve, and the second one-way valve are mounted on the lower pressure plate in the same manner. The second and third airbags expand after inflation, which can protect the patient's teeth and gums. The first and second airbags are connected by a hose. The first and second airbags on the upper pressure plate are connected to the first and second airbags on the lower pressure plate by a retractable corrugated tube. When the pressure inside the second and third airbags is too high, the first and second one-way valves open to release the gas. At the same time, the gas will impact the inner walls of the patient's oral cavity, assisting the patient in puffing out their cheeks.

[0040] The tongue muscle training component includes a placement slot 361 fixedly mounted on the lower pressure plate, a bracket 362 rotatably mounted on the lower pressure plate, a tongue plate 363 rotatably mounted on the bracket, a linkage device 364 fixedly mounted on the base, and a reversing device 365 fixedly mounted on the base and the lower pressure plate. The placement slot is inclined to facilitate the patient placing their tongue on it. The bracket can rotate on the lower pressure plate. The tongue plate can rotate on the bracket and has an arc surface to better fit the patient's tongue. The two ends of the tongue plate are of different lengths, with the end in contact with the tongue being shorter, forming a force-saving lever. When the upper pressure plate moves, the linkage device drives the tongue plate to rotate on the bracket, lifting the patient's tongue. The pressure relief device works in conjunction with the reversing device. When the first airbag is depressurized, it drives the bracket to rotate on the lower pressure plate, i.e., the tongue plate rotates, thereby causing the patient's tongue to swing left and right for tongue muscle training.

[0041] Specifically, the adjustment mechanism includes a third slide groove 21 fixedly mounted on the base, a support rod 22 slidably mounted on the third slide groove, a fourth slide groove 23 fixedly mounted on the base, an adjustment seat 24 rotatably mounted on the fourth slide groove, and a fifth slide groove 25 fixedly mounted on the base. The support rod can slide up and down on the third slide groove and is threaded; the inner wall of the adjustment seat is threaded, and the adjustment seat cooperates with the support rod. Rotating the adjustment seat can drive the support rod to move up and down, thereby adjusting the height of the base to accommodate patients of different heights; the base can rotate on the support rod.

[0042] Specifically, the drive mechanism includes a motor 41 fixedly mounted on the base, an output shaft 42 fixedly mounted on the motor, a pneumatic assembly 43 fixedly mounted on the base and the output shaft, a reduction gearbox 44 fixedly mounted on the output shaft, and a first gear 45 fixedly mounted on the reduction gearbox; the first gear meshes with a gear ring. The motor drives the base to rotate left and right by repeatedly switching its rotation direction, and drives the pneumatic assembly to inflate the first, second, and third airbags; the reduction gearbox is a gear reducer, which is existing technology, used to reduce the rotational speed; the first gear meshes with the gear ring, the motor drives the output shaft to rotate, and after being reduced in speed by the reduction gearbox, it drives the first gear to rotate, which in turn drives the gear ring to rotate, and finally drives the base to rotate on the support rod, realizing neck rotation training.

[0043] Specifically, the pressure relief device includes a valve body 3441 fixedly mounted on the first airbag and the base, a sixth slide groove 3442 fixedly mounted on the valve body, a pressure relief cover 3443 slidably mounted on the sixth slide groove, and a first rack 3444 slidably mounted on the sixth slide groove; the first rack and the valve body are connected by a first spring 3445; the pressure relief cover and the valve body are connected by a second spring 3446. The first spring is a tension spring; the second spring is a compression spring; the pressure relief cover can slide on the sixth slide groove, and the pressure relief cover engages with the first rack; the pressure relief cover is pushed downward by the gas in the first airbag, squeezing the first rack to slide on the sixth slide groove, and the released gas is used to drive the reversing device; the tooth surface lengths on the first rack are different. Compared with racks with the same tooth surface length, the pressure relief cover has greater resistance when moving downward, that is, the air pressure in the first airbag needs to be greater to open the pressure relief cover, that is, the upper pressure plate can move upward a longer distance, thereby allowing the patient's mouth to open further and making the training effect better.

[0044] Specifically, the linkage device includes a seventh slide groove 3641 fixedly mounted on the base, a second rack 3642 fixedly mounted on the upper pressure plate, a third rack 3643 slidably mounted on the seventh slide groove, a second gear 3644 rotatably mounted on the seventh slide groove, and a pressure roller 3645 fixedly mounted on the third rack. The second gear meshes with the second rack and the third rack on both sides respectively. When the upper pressure plate moves upward, it drives the second rack to move, the second rack drives the second gear to rotate, the second gear drives the third rack to move downward, and thus drives the pressure roller to press down on the tongue plate, causing the tongue plate to rotate, lifting the patient's tongue, and performing tongue muscle training.

[0045] Specifically, the reversing device includes a second cavity 3651 fixedly mounted on the lower pressure plate, a baffle 3652 fixedly mounted on the bracket, metal contacts 3653 symmetrically fixedly mounted on the second cavity, and a vent valve 3654 fixedly mounted on the lower pressure plate; the second cavity and the valve body are connected by a second hose 3655; the baffle and the lower pressure plate are connected by a third spring 3656. The second cavity is a sealed cavity; the rotation of the support can drive the baffle to rotate within the second cavity; the metal contact is electrically connected to the ventilation valve to control its opening and closing; initially, the baffle is located on the side of the third spring and is in contact with the inner wall of the second cavity; when the gas in the first airbag enters the second cavity through the second hose, it pushes the baffle to rotate slightly, then the air pressure in the cavity on the side of the baffle and the third spring increases, causing the baffle to continue rotating, which in turn drives the support and tongue plate to rotate, causing the patient's tongue to move; when the baffle rotates and contacts the metal contact on the other side, the ventilation valve opens to release air, the air pressure in the cavity on the side of the baffle and the third spring decreases, the third spring pulls the baffle to rotate back to its original position, which in turn drives the support and tongue plate to rotate in the opposite direction, causing the patient's tongue to move in the opposite direction; when the baffle contacts the metal contact on the side of the third spring, the ventilation valve closes.

[0046] Specifically, the pneumatic assembly includes a third cavity 431 fixed on the base, an eighth slide groove 432 fixed on the third cavity, a ninth slide groove 433 fixed on the output shaft, a push plate 434 slidably disposed on the eighth and ninth slide grooves, a first through groove 435 fixed on the base, a third one-way valve 436 fixed on the first through groove, a second through groove 437 fixed on the base, and a fourth one-way valve 438 fixed on the second through groove; the third cavity and the first airbag are connected by a third hose 439; the third cavity and the second airbag are connected by a fourth hose 430. The third cavity is a cylindrical cavity; the eighth slide is spiral-shaped; the third and fourth one-way valves allow air to enter the third cavity only from the outside in one direction; the motor drives the output shaft to rotate, causing the push plate to rotate along the eighth slide and slide to the left on the ninth slide, compressing the air on the left side of the push plate, allowing the air to enter the first airbag through the third hose, inflating the first airbag. At the same time, the space on the right side of the push plate increases and the air pressure decreases, allowing outside air to enter the space on the right side of the push plate through the fourth one-way valve. When the motor rotates in the opposite direction and the push plate moves to the right, the air on the right side of the push plate enters the second airbag through the fourth hose, inflating the second and third airbags. At the same time, the space on the left side of the push plate increases and the air pressure decreases, allowing outside air to enter the space on the left side of the push plate through the third one-way valve.
