Description

Technical Field

[0001] This invention generally relates to a rehabilitation device. More particularly, this invention relates to an exercise device for swallowing rehabilitation (e.g., for swallowing exercises and jaw exercises). Background Technology

[0002] Swallowing is a complex action involving the muscles and nerves in the mouth, pharynx, and esophagus, as well as the swallowing center in the brain that is connected to the pharynx and esophagus by nerves.

[0003] Dysphagia is a disorder of swallowing function and is broadly described as the inability to move food or liquids from the mouth to the stomach. Dysphagia is a symptom caused by many different reasons and can be due to congenital malformations, structural damage, and / or medical conditions. For example, dysphagia may occur after treatment for head and neck cancer (HNC). It may also occur after a total laryngectomy because the muscles involved in swallowing are removed or cut.

[0004] The impact on the quality of life of people with dysphagia can be significant. For example, subjects with dysphagia may be affected by chronic malnutrition, dehydration, developmental delays, aspiration pneumonia, and exacerbations of chronic lung disease.

[0005] There are many ways to treat dysphagia, and conventional treatments typically include dietary adjustments, compensatory techniques such as postural changes, indirect therapies such as strengthening swallowing muscles, direct therapies such as exercises during swallowing, and medication. The goal of treatment is to maintain adequate nutrition and hydration while maximizing airway protection. Strengthening the swallowing muscles improves swallowing function, potentially reducing reliance on feeding tubes and dietary adjustments. Additionally, the risk of aspiration pneumonia and trismus can be reduced. By minimizing these problems, a higher quality of life can be achieved.

[0006] However, there are problems associated with current intensive therapies. Currently, there are no exercise or rehabilitation devices suitable for individuals who have undergone total laryngectomy. Traditionally, these individuals' swallowing difficulties have been treated primarily through surgical, pharmacological, and coping strategies. For this reason, existing exercise devices do not target all the necessary muscles for individuals who have undergone total laryngectomy. Furthermore, because existing exercise devices are not designed for individuals who have undergone total laryngectomy, they are unsuitable for users with tracheostomies. Existing exercise devices may cover the tracheostomy and / or cause breathing difficulties during use.

[0007] Furthermore, there are currently no exercise or rehabilitation devices that can be used for different exercises. Different exercise devices must be used to train different muscles. Therefore, users would need several different rehabilitation devices for different purposes. In addition, existing exercise devices often have the disadvantages of unknown resistance and the inability to change the resistance. The lack of understanding of the resistance used and the possibility of changing the resistance is also a problem for exercises that do not require exercise devices at all. These exercises also often have the disadvantage of being performed in impractical postures (such as lying down).

[0008] Therefore, improved exercise devices, and especially those that allow for increased user comfort, would be advantageous, as they can be used for different exercises and are also suitable for people who have undergone total laryngectomy. Summary of the Invention

[0037] Figure 6 An exercise device according to an embodiment of the present invention is shown in use. Detailed Implementation

[0038] The following description focuses on embodiments of the exercise device of the present invention, which is applicable to exercise devices and particularly for swallowing rehabilitation. However, it will be understood that the exercise device is also suitable for purposes other than swallowing rehabilitation. Examples of such purposes may be speech training, general jaw training, swallowing training, and other swallowing difficulties.

[0039] Figure 1a A side view of an exercise device 10 for swallowing rehabilitation according to a first embodiment of this disclosure is shown. Swallowing rehabilitation may include, for example, performing swallowing exercises or other jaw exercises. Figure 1a As shown, the exercise device 10 includes an exerciser body 20 forming a support. The exerciser body 20 is curved and adapted to engage with a user using the exercise device 10. In some embodiments, the exerciser body 20 may include a chest rest 23 adapted to engage with the chest of the user using the exercise device 10. Thus, when the exercise device 10 is in use, the chest rest 23 of the exerciser body 20 can rest against the user's chest. At least a portion of the chest rest 23 may be provided with padding 25. The padding 25 may be made of a softer material than the exerciser body 20, and therefore may be more comfortable against the chest than the rest of the exerciser body 20. This can improve user comfort. The padding 25 may be, for example, a foam pad.

[0040] The exercise device 10 further includes a holding device 40 mounted to the exercise body 20. For example... Figure 1a As seen, the retaining device 40 extends from the exercise body 10. The retaining device 40 is configured to retain the chin receiving device 30. The exercise device 10 includes the chin receiving device 30, and the chin receiving device 30 is movably connected to the retaining device 40. The retaining device 40 secures the chin receiving device 30 to the exercise device 10 in a manner that allows the chin receiving device 30 to move relative to the exercise device 10. The chin receiving device 30 is adapted to engage with the chin or jaw of a user using the exercise device 10. Figure 1a As shown, the chin receiving device 30 may include a chin receiving plate 31 for receiving the chin of a user using the exercise device 10. The chin receiving device 30 may further include a connecting member 32 for movably connecting the chin receiving plate 31 to the retaining device 40. In some embodiments, at least a portion of the chin receiving plate 31 of the chin receiving device 30 may be provided with a padding 33. The padding 33 may be made of a softer material than the rest of the chin receiving device 30, and thus may improve user comfort. The padding 33 may be, for example, a foam padding.

[0041] The retaining device 40 can be implemented in different ways, and Figure 1a and Figure 1bAn exemplary embodiment is shown. According to this exemplary embodiment, the retaining device 40 includes an elongated member. The elongated member extends upward from the exerciser body 20. The elongated member is fastened to the exerciser body 20 at one end and configured to receive a chin receiving device 30 at the other end. Thus, the retaining device 40 is securely mounted to the exerciser body 20 at one end. The chin receiving device 30 received at the other end can be received such that it is pivotally attached to the elongated member, i.e., the chin receiving device 30 is movably connected to the retaining device 40. Figure 1b As shown, the chin receiving device 30 can be pivotally connected to the elongated member via at least one pin 45 or a connector. The chin receiving device 30 pivots about the at least one pin 45.

[0042] The exercise device 10 further includes an exercise element 50 for generating resistance as the chin receiving device 30 moves toward the exerciser body 10, i.e., for generating resistance against the user using the exercise device 10. The exercise element 50 is arranged to extend between the exerciser body 20 and the chin receiving device 30. Figure 1a In the illustrated embodiment, one end of the exercise device 50 is secured to the exerciser body 20 via a connecting device 55. The other end of the exercise device 20 can be connected to a chin receiving device 30 without being attached to any fastening device. The chin receiving device 30 is adapted to rest on this other end of the exercise device 50. Therefore, in Figure 1a In the illustrated embodiment, the exercise device 50 is not securely attached to the chin receiving device 30. The exercise device 50 and the chin receiving device 30 are connected to each other only by physical contact generated when they come into contact with each other, without any physical attachment to any fastening device. Therefore, it is possible to lift the chin receiving device 30 upward away from the exercise device 50, so that the exercise device 50 and the chin receiving device 30 are no longer connected to each other. It will be appreciated that, according to another embodiment, the exercise device 50 may be securely attached to the chin receiving device 30 by an attachment device, but not to the exerciser body 20. In yet another embodiment, the exercise device 50 may be securely attached to both the exerciser body 20 and the chin receiving device 30 at both ends.

[0043] In some embodiments, the exercise device 50 can be detachably attached to the exerciser body and / or chin receiving device 30 using an attachment device 55, thereby making the exercise device 50 replaceable. This allows the exercise device 50 to be replaced or replaced with another exercise device 50. This can be used in the event of breakage of the exercise device 50. This can also be used to change the load or resistance formed by the exercise device 50. For example, if the user finds exercising with the exercise device 50 with a certain stiffness or resistance too easy, the exercise device 50 can be replaced with another exercise device 50 with a higher stiffness or resistance. Thus, the amount of resistance formed by the exercise device 50 can be changed. By changing the resistance or load of the exercise device 10, the user of the exercise device 10 can continue to exercise at 60%-70% of their maximum capacity. This ensures that the user's strength will continue to increase.

[0044] In some embodiments, the exercise device 50 can be adjustably attached to the exercise device body and / or the chin receiving device 30 using an attachment device 55. In such embodiments, the attachment device 55 can be disposed in an elongated slot 60, such as... Figure 1b As shown. The attachment device 55 is slidable along the length of the elongated slot 60. Therefore, the position of the exercise device 50 relative to the retaining device 40 and at least one pin 45 is adjustable. The resistance can be changed by adjusting the position of the exercise device 50 relative to the retaining device 40 and at least one pin 45. In this embodiment, the exercise device 50 and the chin receiving device 30 are connected to each other only by physical contact generated when they come into contact with each other, without physical attachment to any fastening device. According to another embodiment, the exercise device 50 can be adjustably attached to the chin receiving device 30 via the attachment device 55, wherein the corresponding elongated slot 60 exists in the connecting member 32, without being fixed to the exerciser body 20. In yet another embodiment, the exercise device 50 can be adjustably attached to both the exerciser body 20 and the chin receiving device 30 at both ends.

[0045] According to the previously described embodiments, the load on the exercise device 10 can be changed by replacing or substituting the exercise device 50. According to another embodiment, the length of the exercise device 50 used to generate resistance can be adjusted by an attachment device 55 attached to the exercise device 50. This allows for a change in the amount of resistance generated by the exercise device 50. The length of the exercise device 50 can also be adjusted to adjust the height of the exercise device 10, making the exercise device more suitable for the user of the exercise device 10.

[0046] The exercise device 50 may include, for example, a spring. An example of this embodiment is... Figure 1a and Figure 1b Displayed in [the text]. For example... Figure 1a and Figure 1bAs seen, the spring is fastened to the exerciser body 20 at one end by an attachment device 55. A chin receiving device 30 rests at the other end of the spring. It is well known that different springs can have different spring constants. Different spring constants result in different stiffnesses, and thus different resistances. Therefore, by selecting a spring with a specific spring constant (i.e., stiffness), the resistance of the exercise device 10 can be adjusted.

[0047] According to another embodiment, the exercise device 50 may include an elastomeric component, such as a silicone block. The resistance of the exercise device 10 can be adjusted according to the size, shape, stiffness, and density of the elastomeric component.

[0048] The exercise device 10 disclosed herein achieves increased user comfort. The design of the exercise device 10 allows the user to perform swallowing rehabilitation in a comfortable posture (e.g., upright). Therefore, the user does not need to lie down to perform the exercise. Additionally, the provided exercise device 10 includes a design having an exerciser body 20 that does not cover the tracheostomy during use. This facilitates breathing while using the exercise device 10 and makes the provided exercise device 10 suitable for users who have undergone total laryngectomy. In some embodiments, to further improve user comfort for users with a tracheostomy, the exercise device 10 may additionally include openings, such as holes or forks, in the exerciser body 20. These openings allow air to freely flow in and out of the tracheostomy through the holes in the exerciser body 20.

[0049] Furthermore, by utilizing a chin receiving device 30 that is movable relative to the exerciser body 20, the user can receive tactile feedback while performing swallowing rehabilitation. By receiving direct feedback while performing swallowing rehabilitation, the user experience can be improved, which can motivate the user to continue using the exercise device 10.

[0050] In some embodiments, the exercise device 10 may further include a handle 65. The handle 65 may be attached to a corresponding end of the bending exerciser body 20. By providing a handle connecting to the outer end of the exerciser body 20, the exerciser body 20 and the handle 65 form a closed loop, and thus provide a robust and secure construction for the exercise device 10. With the handle 65, which a user can grip during use, the exercise device 10 is also easier to operate and easier to maintain in the correct position during exercise.

[0051] Figure 2a The exercise device 10 in use is shown. Figure 2aIn this embodiment, the user holds the exercise device 10 in the starting position, i.e., before any swallowing rehabilitation has begun. The exercise device 10 according to this embodiment includes a handle 65 that the user holds during use. As shown in the figure, in the starting position, the chest rest 23 of the exercise device body 20 rests against the user's chest, and the user's chin rests on the chin receiving plate 31.

[0052] One of the advantages of the exercise device 10 presented herein is that it can be used for multiple different exercises. The exercise begins from the previously described starting position, and from this position, multiple different exercises can be performed. Reference will now be made to... Figures 2b to 2d Describe some of these exercises.

[0053] Figure 2b The exercise, referred to herein as "chin tuck resistance," is illustrated. This exercise is performed by pressing the chin down towards the chest of the user using exercise device 10. The chin rests on a chin receiving device 30. As the user presses their chin down, the chin receiving device 30 pivots about pin 45 and moves toward the exerciser body 20. The final position when the chin receiving device 30 is fully pushed toward the exerciser body 20 is... Figure 2b As shown in the diagram, the exercise device 50 creates resistance, requiring the user to exert a certain force to push the chin-receiving device 30 downwards. The purpose of this exercise is to strengthen the muscles that pull the throat and hyoid bone upwards and forwards, and to improve swallowing ability. The muscles targeted by the chin-tucking exercise are the same as those in well-known "shaker exercises" (also known as "head-lifting exercises"). In these exercises, the user lies supine and lifts their head to look at their toes. Compared to shaker exercises, the chin-tucking exercise using the exercise device 10 can be performed in a much more comfortable posture (e.g., an upright posture). Furthermore, by using the replaceable or adjustable exercise device 50, the load exposed to the user can be known and adjustable.

[0054] Another exercise that can be performed using exercise device 10 is... Figure 2c It is displayed in the middle. Figure 2c The exercise, referred to herein as "jaw-opening resistance," is illustrated. This exercise is performed by pressing the jaw downwards against the exerciser body 20 of the exercise device 10. The chin rests on a chin receiving device 30. When the user opens their mouth and presses their jaw downwards, the chin receiving device 30 pivots around a pin 45 and moves toward the exerciser body 20. The exercise device 50 creates resistance, requiring the user to exert a certain force to push the chin receiving device 30 downwards using their jaw. Figure 2cThe final position of the jaw-opening exercise is shown, that is, the final position when the jaw has pushed the chin receiving device 30 downwards all the way to the exerciser body 20. The jaw-opening exercise targets the same muscles as the well-known "Masako exercise." The intention is to improve the movement and strength of the posterior pharyngeal wall during swallowing. This exercise can also improve tongue root movement during swallowing and improve muscle pressure in response to food and liquids.

[0055] Another exercise that can be performed using exercise device 10 is Figure 2d It is displayed in the middle. Figure 2d This illustrates an exercise that can be called "forced swallowing." This exercise strengthens the contraction of the tongue base and pharyngeal pressure during swallowing to reduce residue in the pharyngeal fossa. The purpose of this exercise is to improve the contact and coordination between the different muscles used during swallowing. Figure 2d As seen in the image, the exercise is performed by pressing the chin against the chin receiving device 30 and then swallowing.

[0056] In summary, the three previously described exercises can target the suprahyoid and infrahyoid muscles (for larynx elevation), the sternocleidomastoid muscle, and the lateral pterygoid muscle (for mouth opening and trismus prevention). Therefore, by using the provided exercise device 10, anterior tongue strength can be increased, maximum mouth opening can be increased, and muscle volume and strength can be increased. Thus, the provided exercise device 10 targets all muscles that can be trained in a person who has undergone total laryngectomy. Furthermore, since the load of the exercise device 50 can be known, an exercise device 10 with an appropriate load can be selected for a specific user, and potentially the load can be increased as the muscles become stronger.

[0057] Now refer to Figure 3a Another embodiment of this disclosure is described. The exercise device 10 according to this embodiment is embodied in a manner corresponding to the exercise device shown in the foregoing figures, but with a different construction of the holding device 40. As... Figure 3a As shown, the retaining device 40 of the exercise device 10 includes two slightly curved members. The two curved members are fastened to the exerciser body 20 at one end. They extend in a direction away from the exerciser body 20. Each of the two curved members includes a guide rail 41 configured to receive a chin receiving device 30. Figure 3b This is a perspective view of the exercise device 10 according to this embodiment. Figure 3bAs seen, the retaining device 40 includes two curved members securely mounted to the exerciser body 20 at one end. A chin receiving device 30 is movably connected to the curved members, allowing the chin receiving device 30 to move within a guide rail 41. In some embodiments, the chin receiving device 30 may include two engaging devices 35. The engaging devices 35 extend radially from the chin receiving device 30 and are configured to engage with the guide rail of the retaining device 40, such that the engaging devices 35 are held within the guide rail during movement of the chin receiving device 30.

[0058] Figure 4 The previously described embodiments in use are shown. (As from...) Figure 4 It is understood that when the user pushes their chin downwards (i.e., toward the chest), the chin receiving device 30 will slide within the guide rail toward the exerciser body 20. When the chin receiving device 30 is pushed downwards, the exerciser 50 will create resistance against the chin receiving device 30, thereby forcing the user to push harder. Figure 4 As seen, the chin receiving device 30 will pivot centrally around the neck of the user using the exercise device 10. The described embodiment provides a robust and sustainable construction for the exercise device 10.

[0059] Figure 5a A cross-sectional view of an exercise device 10 for swallowing rehabilitation according to a third embodiment of this disclosure is shown. Figure 5a The exercise device 10 shown includes an adjustment lever 70, which allows adjustment of the resistance against movement of the chin receiving device.

[0060] like Figure 5a As shown, the exercise device 10 includes an exerciser body 20 for supporting the device 10 during use. The exerciser body 20 may have a chest support plate 23 adapted to engage with the chest of a user using the exercise device 10. The chest support plate 23 may have padding (not shown), such as padding 25 as shown in Figure 1.

[0061] The exercise device 10 also includes a chin receiving device 30, which is movably connected to the exerciser body 20. The chin receiving device 30 includes a chin rest 31 and a pad (not shown), such as the pad 33 shown in FIG. 1. The chin receiving device 30 also includes a connecting member 32 connected to the exerciser body 20. Figure 5a In this embodiment, the chin receiving device 30 is connected via the retaining device 40 (in Figure 5b (As shown in the image) and pin 45 are connected to the exerciser body 20. The chin receiving device 30 is pivotable about pin 45.

[0062] The exercise device 10 also includes an adjusting lever 70. The adjusting lever 70 includes an elongated member pivotable about an adjusting pin 75. The adjusting lever 70 is connected to the exerciser body 20 via a retaining device 40 and the adjusting pin 75. At one end, the adjusting lever 70 includes a roller 80 that contacts the lower surface of the connecting member 32 of the chin receiving device 30. In operation, as the chin receiving device 30 moves toward the exerciser body 20, the chin receiving device 30 interacts with the roller 80, causing the adjusting lever 70 to pivot about the adjusting pin 75.

[0063] exist Figure 5a In this embodiment, the exercise device 50 is disposed between the exerciser body 20 and the adjusting lever 70. The exercise device 50 may be a compression spring, similar to those used in the previously described embodiments, or an elastomeric component, such as a silicone block. Figure 5a As shown, in some embodiments, the exercise device 50 is disposed inside the handle 65 of the exercise device 10.

[0064] A load arrangement is provided to connect the adjusting lever 70 to the exercise device 50. The load arrangement may include a connecting element 85, such as a wire or cable, connected to the adjusting lever 70 at the end opposite to the roller 80. The load arrangement may also include a stop 90, such as a spring washer, connected to the other end of the connecting element 85. The exercise device 50 is disposed between the lever arm 70 and the stop 90. For example, the connecting element 85 may extend through the axis of the exercise device 50. The adjusting lever 70, the connecting element 85, and the stop 90 are operable to compress the exercise device 50 during operation of the device 10, such as by adjusting the lever arm 70. Figure 5c Discussed.

[0065] Figure 5a The exercise device 10 shown provides adjustable or variable resistance against movement of the chin receiving device 30 toward the exerciser body 20. To achieve this, the pivot position of the adjusting lever 70 is adjustable. Figure 5a As shown, the adjusting lever 70 includes a toothed rail 95 configured to receive an adjusting pin 75. The toothed rail 95 includes a plurality of adjacent positions for receiving the adjusting pin 75, these positions defining different pivoting positions of the adjusting lever 70. The adjusting pin 75 is positioned in one of the positions of the toothed rail 95 and provides pivoting of the adjusting lever 70 about that position. Therefore, the pivoting position can be adjusted along the length of the adjusting lever 70 by moving the adjusting pin 75 between the positions in the toothed rail 95. It should be understood that the pivoting position of the adjusting lever 70 can be adjusted in any suitable manner (e.g., by a sliding mechanism).

[0066] By adjusting the pivot position of the adjusting lever 70, the resistance provided by the device 10 can be increased or decreased as needed. This is because adjusting the pivot position of the adjusting lever 70 changes the length of the adjusting lever 70 on either side of the pivot. If the adjusting lever 70 has a length x and the distance from one end of the adjusting lever 70 to the pivot position is y, then the leverage ratio is defined as y / (xy). Thus, by changing the pivot position, the distance y and the leverage ratio can be changed without changing the length of the adjusting lever. Therefore, an extendable or retractable lever arm that may not always be used is unnecessary. This allows for a compact design that still provides a wide range of resistance against the movement of the chin receiving device 30 toward the exerciser body 20.

[0067] Each pivot position can increase or decrease the resistance by a set amount relative to an adjacent position. For example, when the adjusting pin 75 is in the minimum resistance position closest to the exercise device 50, the resistance can be approximately 20 N. Each successive pivot position can increase the resistance by approximately 20 N until the maximum resistance position furthest from the exercise device 50, at which position the resistance can be approximately 160 N.

[0068] Figure 5b A perspective view of the exercise device according to this embodiment is shown. Figure 5b As shown, the retaining device 40 connects the chin receiving device 30 to the exerciser body 20 via a pin 45. The retaining device 40 also connects the adjusting lever 70 to the exerciser body 20 via an adjusting pin 75.

[0069] For example Figure 5b As shown, there is an adjustment knob 100 that allows the adjustment pin 75 to move between positions in the gear 95. The adjustment knob 100 can be rotated to the open position to allow the adjustment pin 75 to move between pivot positions. The adjustment knob 100 can then be rotated to the closed position to lock the adjustment pin 75 in place.

[0070] Figure 5b It is also shown that the connecting member 32 of the chin receiving device 30 has a forked structure at one end. That is, the connecting member 32 includes a single first arm 32a connected to the chin receiving plate 31 and two parallel second arms 32b connected to the pin 45. This structure allows one end of the adjusting lever 70 to pass between the second arms 32b when the adjusting lever 70 pivots about the adjusting pin 75. This will be about Figure 5c Let's have a discussion.

[0071] Figure 5cA cross-sectional view of the previously described embodiment in use is shown. When a user pushes their chin down (i.e., toward their chest), the chin receiving device 30 pivots about pin 45. This causes roller 80 to move along the lower surface of the first arm 32a of connecting member 32, which in turn causes adjusting lever 70 to pivot counterclockwise about adjusting pin 75. Subsequently, one end of adjusting lever 70 passes upward between the second arms 32b of chin receiving device 30 and pulls upward on connecting member 85 and stop 90. This results in compression of exercise device 50, which provides resistance against the user pushing their chin down. Thus, the user can perform the exercises discussed above to strengthen the relevant muscles. As discussed above, the resistance of exercise device 10 can be adjusted by changing the position of adjusting pin 75.

[0072] In some examples, the exercise device 50 may include multiple springs, each of which can be activated individually. These springs may be arranged in a magazine arrangement. Each spring may have individual resistance, and the maximum resistance may depend on the number of springs used. For example, a spring magazine may include eight springs, each with a resistance of 20 N. Due to the individual activation of the springs, a resistance range from 20 N to 160 N can be achieved.

[0073] Figure 6 The exercise device 10 in use is shown. Figure 6 During use, the user holds the exercise device 10 in the starting position, i.e., before any swallowing rehabilitation has begun. The user holds the handle 65 during use. Figure 6 As seen, in the starting position, the chest rest plate 23 of the exerciser body 20 rests against the user's chest, and the user's chin rests on the chin receiving plate 31. The exercise device 10 can be used for various exercises starting from this starting position.
