Description

Technical Field

[0001] This invention relates to the field of swallowing rehabilitation technology, and more specifically to a swallowing rehabilitation exercise device. Background Technology

[0002] Swallowing rehabilitation training is a rehabilitation intervention for people with swallowing dysfunction (such as patients with stroke, traumatic brain injury, Parkinson's disease, and head and neck tumors after surgery). The core goal is to improve swallowing coordination, strengthen swallowing-related muscles, and reduce the risk of aspiration. It is mainly divided into two categories: basic training and functional training. Basic training includes lip muscle training, tongue muscle training, and dry swallowing training.

[0003] Tongue muscle training typically involves forward tongue extension and left and right tongue extension exercises. The core purpose is to improve the flexibility and lateral contraction ability of the tongue muscles, which is crucial for swallowing function. For example, when eating, the tongue needs to move to the sides to push food to the molars for chewing, and it also needs to adjust the position of food in the mouth through lateral movements to avoid food residue.

[0004] However, most existing swallowing rehabilitation exercise devices can only perform single tongue protrusion training or lateral tongue protrusion training, making it difficult to simultaneously achieve compound training of tongue muscle protrusion and lateral movement. This fails to fully activate the synergistic contraction ability of different tongue muscle groups, resulting in poor tongue muscle training effects. Therefore, to address the above technical problems, a swallowing rehabilitation exercise device is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a swallowing rehabilitation exercise device that facilitates simultaneous compound training of tongue muscle protrusion and lateral movement, thereby improving the effectiveness of tongue muscle training.

[0006] A swallowing rehabilitation exercise device, comprising: The base has a mounting bracket that slides along its length at its top. A drive mechanism is disposed on the base and connected to the mounting seat, for driving the mounting seat to reciprocate along the length of the base; An adsorption assembly includes a mounting rod and a suction nozzle. The mounting rod is rotatably mounted on the top of a mounting base about a vertical axis. The suction nozzle is located at one end of the mounting rod and can communicate with a negative pressure device for adsorbing and fixing a tongue tip. A transmission mechanism is provided on the mounting base and connects the base and the mounting rod, for converting the reciprocating movement of the mounting base into the reciprocating swing of the mounting rod.

[0007] The beneficial effects of the above-mentioned swallowing rehabilitation exercise device are as follows: By placing the suction nozzle on the tip of the patient's tongue and using a negative pressure device to generate suction, the nozzle can be fixed to the tip of the tongue. Then, the drive mechanism drives the mounting base to move the mounting rod back and forth, which in turn causes the patient's tongue to perform tongue muscle protrusion. During the reciprocating movement of the mounting base, the transmission mechanism drives the mounting rod to swing back and forth, which in turn causes the patient's tongue to swing left and right. This provides a compound training of tongue muscle protrusion and lateral swinging, thereby improving the tongue muscle exercise effect.

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] Please see Figure 1 and Figure 2 One embodiment of a swallowing rehabilitation exercise device includes a base 10, a drive mechanism, an adsorption assembly, and a transmission mechanism. A mounting seat 101 is slidably disposed at the top of the base 10 along its length. The drive mechanism is disposed on the base 10 and connected to the mounting seat 101, for driving the mounting seat 101 to reciprocate along the length of the base 10. The adsorption assembly includes a mounting rod 20 and a suction nozzle 201. The mounting rod 20 is rotatably disposed at the top of the mounting seat 101 about a vertical axis, and the suction nozzle 201 is disposed at one end of the mounting rod 20 and can communicate with a negative pressure device for adsorbing and fixing the tip of the tongue. The transmission mechanism is disposed on the mounting seat 101 and connects the base 10 and the mounting rod 20, for converting the reciprocating movement of the mounting seat 101 into the reciprocating oscillation of the mounting rod 20.

[0022] In the above embodiment, by placing the suction nozzle 201 over the tip of the patient's tongue and then using a negative pressure device to generate suction, the suction nozzle 201 can be fixed to the tip of the tongue. Then, by driving the mounting base 101 through the drive mechanism to move the mounting rod 20 back and forth, the patient's tongue can be moved forward to perform tongue muscle protrusion. During the reciprocating movement of the mounting base 101, the transmission mechanism drives the mounting rod 20 to swing back and forth. The swinging of the mounting rod 20 can move the patient's tongue left and right, thereby performing compound training of tongue muscle protrusion and left and right swinging at the same time, improving the tongue muscle training effect.

[0023] Specifically, in the above embodiment, the top of the base 10 has two sets of T-shaped grooves 105 facing each other, and the bottom of the mounting base 101 has two sets of T-shaped sliders 106 facing each other. The two sets of T-shaped sliders 106 are slidably disposed in the T-shaped grooves 105 along the length of the base 10, ensuring the stability of the sliding of the mounting base 101.

[0024] Please see Figure 1 and Figure 2 In one embodiment, the driving mechanism includes a motor 30, a first turntable 301, and a first lever 302. The motor 30 is mounted on the base 10, and the first turntable 301 is coaxially mounted on the output end. The first lever 302 is eccentrically mounted on one end of the first turntable 301. A connecting rod 102 is mounted on one side of the mounting base 101. A first groove 103 is opened on one side of the connecting rod 102 in the vertical direction. The first lever 302 is slidably mounted in the first groove 103.

[0025] In the above embodiment, the motor 30 drives the first turntable 301 to rotate, and the rotation of the first turntable 301 causes the first lever 302 to revolve. The first lever 302 revolve and slides with the first lever groove 103, which can drive the mounting base 101 to move back and forth through the connecting rod 102, making it convenient to drive the mounting base 101 to move back and forth.

[0026] Please refer to the following: Figure 3 Based on the above embodiments, the driving mechanism further includes a first screw 303; a first groove 304 is provided at one end of the first turntable 301, and one end of the first lever 302 is slidably disposed in the first groove 304 along the radial direction of the first turntable 301. The first screw 303 is arranged radially along the first turntable 301 and is rotatably disposed in the first groove 304 and threadedly connected to the first lever 302.

[0027] In the above embodiments, the first lever 302 can be driven to slide by rotating the first screw 303 in threaded engagement with the first lever 302, thereby changing the eccentricity of the first lever 302. It can be understood that when the eccentricity of the first lever 302 increases, the reciprocating stroke of the mounting base 101 driven by the first lever 302's revolution and sliding engagement with the first lever groove 103 increases; when the eccentricity of the first lever 302 decreases, the reciprocating stroke of the mounting base 101 driven by the first lever 302's revolution and sliding engagement with the first lever groove 103 decreases. This makes it easier to adjust the tongue protrusion length according to different patients, making it convenient for different patients to use and improving the practicality of the device.

[0028] Please see Figure 1 , Figure 2 and Figure 4In one embodiment, the transmission mechanism includes a second turntable 40, a second lever 401, and a transmission assembly. The second turntable 40 is rotatably disposed on one side of the mounting base 101. The top end of the second lever 401 is eccentrically disposed. The top end of the mounting rod 20 has a through second groove 202 along its length direction. The second lever 401 is slidably disposed in the second groove 202. The transmission assembly connects the second turntable 40 and the base 10 and is used to convert the movement of the mounting base 101 into the rotation of the second turntable 40.

[0029] In the above embodiment, the movement of the mounting base 101 drives the second turntable 40 to rotate through the transmission assembly. The rotation of the second turntable 40 drives the second lever 401 to revolve. The revolve of the second lever 401 and the second lever groove 202 can drive the mounting rod 20 to swing back and forth, making it convenient to drive the mounting rod 20 to swing back and forth.

[0030] Based on the above embodiments, the transmission mechanism further includes a second screw 402; a second groove 403 is provided at the top of the second turntable 40; one end of the second lever 401 is slidably disposed in the second groove 403 along the radial direction of the second turntable 40; the second screw 402 is arranged radially along the second turntable 40 and is rotatably disposed in the second groove 403, and is threadedly connected to the second lever 401.

[0031] In the above embodiments, the second lever 401 can be driven to slide by rotating the second screw 402 in threaded engagement with the second lever 401, thereby changing the eccentricity of the second lever 401. It can be understood that when the eccentricity of the second lever 401 increases, the reciprocating swing amplitude of the mounting rod 20 increases due to the revolving engagement of the second lever 401 and the sliding engagement of the second lever groove 202. Conversely, when the eccentricity of the second lever 401 decreases, the reciprocating swing amplitude of the mounting rod 20 decreases due to the revolving engagement of the second lever 401 and the sliding engagement of the second lever groove 202. This facilitates the adjustment of the left and right swing amplitude of the tongue according to different patients, making it easier for different patients to use and improving the practicality of the device.

[0032] Please see Figure 2 and Figure 4 In one embodiment, the transmission assembly includes a gear 404 and a rack 405; the gear 404 is coaxially arranged at the bottom end of the second turntable 40, and the rack 405 is arranged at the top end of the base 10 along its length direction, and the rack 405 meshes with the gear 404.

[0033] In the above embodiment, the mounting base 101 moves by driving the gear 404 to move via the second turntable 40. The gear 404 moves and meshes with the rack 405, which causes the gear 404 to rotate. The rotation of the gear 404 drives the second turntable 40 to rotate. Driving the second turntable 40 to rotate is convenient and does not require additional power components or additional operations. It is easy to use and reduces energy consumption.

[0034] Please see Figures 4 to 6Based on the above embodiments, the transmission mechanism further includes a limiting component; the gear 404 is rotatably mounted coaxially on the shaft 406 at the bottom of the second turntable 40, and the limiting component connects the second turntable 40 and the shaft 406 to restrict the shaft 406 from reversing when the mounting base 101 moves to reset the tongue.

[0035] In the above embodiment, the limiting component restricts the rotation of the rotating shaft 406 when the tongue is reset by moving the mounting base 101. When the rotating shaft 406 stops rotating, the second turntable 40 stops rotating. When the second turntable 40 stops rotating, the mounting rod 20 stops swinging back and forth, so that it does not swing left and right when retracting the tongue, which is more in line with the normal tongue retraction action, avoids damaging the contraction coordination of the tongue muscles, and ensures the training effect.

[0036] Please see Figure 6 In one embodiment, the limiting assembly includes an inner ratchet 50, a pawl 501, and a torsion spring 502. The inner ratchet 50 is coaxially disposed at the top of the gear 404, and a mounting groove 407 is provided on the circumference of the rotating shaft 406. The pawl 501 is rotatably disposed in the mounting groove 407, and the torsion spring 502 connects the pawl 501 to the inner wall of the mounting groove 407 and is used to apply a torque to the pawl 501 that meshes with the inner ratchet 50.

[0037] In the above embodiment, when the mounting base 101 moves to cause the patient's tongue to extend forward, the mounting base 101 drives the gear 404 to move and mesh with the rack 405, driving the gear 404 to rotate. The rotation of the gear 404 drives the inner ratchet 50 to rotate. The rotation of the inner ratchet 50 abuts against the pawl 501, driving the rotating shaft 406 to rotate. The rotation of the rotating shaft 406 drives the second turntable 40 to rotate, so that the mounting rod 20 can simultaneously cause the patient's tongue to extend forward and swing left and right. When the mounting base 101 moves in the opposite direction to cause the patient to retract their tongue, the mounting base 101 drives the gear 404 to move in the opposite direction and mesh with the rack 405, driving the gear 404 to rotate in the opposite direction. The rotation of the gear 404 in the opposite direction drives the inner ratchet 50 to rotate in the opposite direction. The rotation of the inner ratchet 50 in the opposite direction cancels the abutment with the pawl 501 and causes the pawl 501 to slide along the inner side of the inner ratchet 50, thereby preventing the rotating shaft 406 from reversing and making it easier to restrict the reversal of the rotating shaft 406.

[0038] Please see Figure 1 and Figure 7 In one embodiment, the system further includes a base plate 104, and the base 10 is mounted on the base plate 104 via a lifting assembly. Specifically, the lifting assembly includes a telescopic column 60 and a third screw 601; the telescopic column 60 is vertically mounted on the top of the base plate 104, the base 10 is vertically slidably mounted on the telescopic column 60, and the third screw 601 is vertically arranged and rotatably mounted on the base 10, and is threadedly connected to the telescopic column 60.

[0039] In the above embodiment, by rotating the third screw 601 and engaging the telescopic column 60 with the thread, the base 10 can be moved upward by rotating the third screw 601 and engaging the telescopic column 60 with the thread, and conversely, by reversing the third screw 601 and engaging the telescopic column 60 with the thread, the base 10 can be moved downward. The height of the suction nozzle 201 can be adjusted according to the actual needs of the patient to facilitate use by different patients.

[0040] The specific implementation method of the above-mentioned swallowing rehabilitation exercise device is as follows: By placing the suction nozzle 201 over the tip of the patient's tongue and then using a negative pressure device to generate suction, the suction nozzle 201 can be fixed to the tip of the tongue.

[0041] Then, the motor 30 drives the first turntable 301 to rotate, and the rotation of the first turntable 301 causes the first lever 302 to revolve. The revolve of the first lever 302 and its sliding engagement with the first lever groove 103 can drive the mounting base 101 to move back and forth through the connecting rod 102. The reciprocating movement of the mounting base 101 can drive the patient to perform tongue muscle protrusion movements through the mounting rod 20.

[0042] Simultaneously, when the mounting base 101 moves to extend the tongue forward, the mounting base 101 drives the gear 404 to move and mesh with the rack 405, driving the gear 404 to rotate. The rotation of the gear 404 drives the inner ratchet 50 to rotate. The rotation of the inner ratchet 50 abuts against the pawl 501, driving the rotating shaft 406 to rotate. The rotation of the rotating shaft 406 drives the second turntable 40 to rotate. The rotation of the second turntable 40 drives the second lever 401 to revolve. The revolve of the second lever 401 and the second lever groove 202 can drive the mounting rod 20 to swing back and forth. The reciprocating swing of the mounting rod 20 can drive the patient's tongue to swing left and right, thereby performing compound training of tongue muscle extension and left and right swing at the same time, improving the tongue muscle training effect.

[0043] Furthermore, when the mounting base 101 moves in the reverse direction to cause the patient to retract their tongue, the mounting base 101 drives the gear 404 to move in the reverse direction and mesh with the rack 405, driving the gear 404 to rotate in the reverse direction. The reverse rotation of the gear 404 drives the inner ratchet 50 to rotate in the reverse direction. The reverse rotation of the inner ratchet 50 cancels the contact with the pawl 501 and causes the pawl 501 to slide along the inner side of the inner ratchet 50, thus preventing the rotating shaft 406 from reversing. At this time, the rotating shaft 406 stops rotating, causing the second turntable 40 to stop rotating. When the second turntable 40 stops rotating, the mounting rod 20 stops swinging, thus preventing the tongue from swinging left and right during retraction, which is more in line with the normal tongue retraction action, avoids disrupting the contraction coordination of the tongue muscles, and ensures the training effect.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
