Description

[Technical Field]

[0001] The present invention relates generally to rehabilitation devices, and more particularly to a training device for swallowing rehabilitation, for example for use in swallowing training and mouth opening training. [Background technology]

[0002] Swallowing is a complex action that involves muscles and nerves in the oral cavity, pharynx, and esophagus, as well as swallowing centers in the brain that are innervated to the pharynx and esophagus.

[0003] Dysphagia is a disorder of the swallowing motility and generally refers to the inability to move food or liquid from the mouth to the stomach. Dysphagia is a symptom that results from many different causes and can result from congenital abnormalities, structural damage, and / or medical conditions. For example, dysphagia can occur after treatment for head and neck cancer (HNC). Dysphagia can also occur after total laryngectomy, when the muscles involved in swallowing are removed or resected.

[0004] The impact of dysphagia on a patient's quality of life can be substantial. For example, those with dysphagia may be affected by chronic malnutrition, dehydration, failure to thrive, aspiration pneumonia, and exacerbation of chronic lung disease.

[0005] There are many approaches to treating dysphagia, and traditional treatments for dysphagia generally include compensatory measures such as food modification and postural changes, indirect therapies such as strengthening exercises for the swallowing muscles, direct therapies such as exercises during swallowing, and medical therapies. The goals of treatment are to maintain adequate nutrition and hydration intake and maximize airway protection. Strengthening exercises can train the swallowing muscles and improve swallowing function. This may result in reduced dependency on feeding tubes and food modification. Furthermore, the risk of aspiration pneumonia and trismus may be reduced. By reducing the aforementioned problems, a higher quality of life may be achieved.

[0006] However, current intensification therapies have associated challenges. Currently, there are no training or rehabilitation devices suitable for individuals who have undergone total laryngectomy. Traditionally, swallowing disorders in these individuals have primarily been treated through surgical, pharmacological, and coping strategies. As a result, existing training devices do not target all of the muscles necessary for individuals who have undergone total laryngectomy. Furthermore, because existing training devices are not intended for individuals who have undergone total laryngectomy, these training devices are not suitable for users with a tracheostoma. Existing training devices may cover the stoma and / or make breathing difficult during use of the training device.

[0007] Furthermore, currently, there are no training or rehabilitation devices available for different exercises. To train different muscles, different training devices must be used. Therefore, users must have several different rehabilitation devices for different purposes. In addition, existing training devices generally have the disadvantage that the resistance used in the exercise is unknown and the resistance cannot be changed. The lack of knowledge of the resistance used and the inability to change the resistance are also problems in exercises that do not require any training device at all. Another disadvantage is that these exercises are often performed in an awkward position, such as lying down.

[0008] Therefore, an improved training device would be advantageous, in particular one that allows for increased user comfort, can be used for different training exercises, and is also suitable for people who have undergone total laryngectomy.

[0026] The following description focuses on an embodiment of the present invention applicable to training devices, and in particular to training devices for swallowing rehabilitation. However, it can be understood that the training device is also suitable for purposes other than swallowing rehabilitation. Examples of such purposes can be speech training, general jaw training, swallowing training, and other dysphagia conditions.

[0027] FIG. 1a shows a side view of a training device 10 for swallowing rehabilitation according to a first embodiment of the present disclosure. Swallowing rehabilitation may include, for example, swallowing training or other mouth-opening exercises. As shown in FIG. 1a, the training device 10 includes a training device body 20 forming a support. The training body 20 is curved and adapted to engage with a user using the training device 10. In some embodiments, the training device 20 may include a chest-supporting plate 23 adapted to engage with the chest of a user using the training device 10. Thus, when the training device 10 is in use, the chest-supporting plate 23 of the training device body 20 may rest on the user's chest. At least a portion of the chest-supporting plate 23 may include a pad 25. The pad 25 may be made of a softer material than the training device body 20 and may therefore be more comfortable against the chest than the remainder of the training device body 20. This may improve user comfort. The pad 25 may be, for example, a foam pad.

[0028] The training device 10 further includes a holding means 40 attached to the training body 20. As shown in FIG. 1a, the holding means 40 extends from the training body 10. The holding means 40 is configured to hold a chin rest means 30. The training device 10 includes a chin rest means 30, which is movably connected to the holding means 40. The holding means 40 secures the chin rest means 30 to the training device 10 such that the chin rest means 30 is movable relative to the training device 10. The chin rest means 30 is adapted to engage with the chin or jaw of a user using the training device 10. As shown in FIG. 1a, the chin rest means 30 may include a chin rest plate 31 for receiving the chin of a user using the training device 10. The chin rest means 30 may further include a connecting member 32 for movably connecting the chin rest plate 31 to the holding means 40. In some embodiments, at least a portion of the chin rest plate 31 of the chin rest means 30 may include a pad 33. The pad 33 may be of a softer material than the rest of the chin rest means 30, and therefore may provide improved comfort to the user. The pad 33 may be, for example, a foam pad.

[0029] The holding means 40 may be realized in different ways, and FIGS. 1a and 1b show one exemplary embodiment. The holding means 40 according to this exemplary embodiment includes an elongated member. The elongated member extends upward from the training device main body 20. The elongated member is fixed to the training device main body 20 at one end and is configured to receive the chin rest means 30 at the other end. Thus, the holding means 40 is rigidly attached to the training device main body 20 at one end. The chin rest means 30 received at the other end may be pivotally attached to the elongated member. That is, the chin rest means 30 is movably connected to the holding means 40. As shown in FIG. 1b, the chin rest means 30 may be pivotally attached to the elongated member by at least one pin 45 or joint. The chin rest means 30 pivots around the at least one pin 45.

[0030] The training device 10 further includes a training means 50 for generating resistance when the chin rest means 30 moves toward the training apparatus main body 10, i.e., for generating resistance to a user using the training device 10. The training means 50 is arranged to extend between the training apparatus main body 20 and the chin rest means 30. According to the embodiment shown in FIG. 1a, one end of the training means 50 is attached to the training apparatus main body 20 by an attachment device 55. The other end of the training means 20 can be connected to the chin rest means 30, but is not attached using a fastening means. The chin rest means 30 is adapted to be placed on this other end of the training means 50. Therefore, in the embodiment shown in FIG. 1a, the training means 50 is not rigidly attached to the chin rest means 30. The training means 50 and the chin rest means 30 are connected to each other only by physical contact that occurs when they come into contact with each other, but are not physically attached using a fastening means. Therefore, it may be possible to lift the chin rest means 30 in an upward direction from the training means 50 so that the training means 50 and the chin rest means 30 are no longer connected to each other. According to another embodiment, it can be realized that the training means 50 may be firmly attached to the chin rest means 30 by an attachment device, but not to the training apparatus main body 20. In yet another embodiment, the training means 50 may be firmly attached to both the training apparatus main body 20 and the chin rest means 30 at both ends.

[0031] In some embodiments, the training means 50 may be removably attached to the training apparatus body and / or the chin rest means 30 by an attachment device 55, thereby making the training means 50 replaceable. This allows the training means 50 to be replaced or exchanged with another training means 50. This may be usable if the training means 50 is broken. This may also be used to change the load or resistance generated by the training means 50. For example, if a user finds training with a training means 50 having a certain stiffness or resistance too easy, the user can replace the training means 50 with another training means 50 having a different stiffness or resistance. This allows the amount of resistance generated by the training means 50 to be changed. By changing the resistance or load of the training device 10, a user using the training device 10 can continue training at 60-70% of their maximum capacity. This ensures that the user's muscle strength continues to increase.

[0032] In some embodiments, the training means 50 may be adjustably attached to the training apparatus body and / or the chin rest means 30 by an attachment device 55. In such embodiments, the attachment device 55 may be disposed in an elongated slot 60, as shown in FIG. 1b. The attachment device 55 is slidable along the length of the elongated slot 60. Thus, the position of the training means 50 relative to the holding means 40 and the at least one pin 45 is adjustable. By adjusting the position of the training means 50 relative to the holding means 40 and the at least one pin 45, the resistance can be varied. In such embodiments, the training means 50 and the chin rest means 30 are connected to each other only by physical contact that occurs when they come into contact with each other, but are not physically attached using fastening means. According to another embodiment, the training means 50 may be adjustably attached to the chin rest means 30 by the attachment device 55 using corresponding elongated slots 60 in the connecting member 32, but is not attached to the training apparatus body 20. In yet another embodiment, the training means 50 may be adjustably attached to both the training apparatus body 20 and the chin rest means 30 at both ends.

[0033] According to the above embodiment, the load of the training device 10 may be changed by exchanging or replacing the training means 50. According to another embodiment, the length of the training means 50 for providing resistance may be adjustable by the attachment device 55 to which the training means 50 is attached, thereby changing the amount of resistance provided by said training means 50. The length of the training means 50 may also be adjusted to adjust the height of the training device 10 so that the training device 10 is better adapted to the user using the training device 10.

[0034] The training means 50 may include, for example, a spring. An example of such an embodiment is shown in FIGS. 1a and 1b. As shown in FIGS. 1a and 1b, the spring is fixed at one end to the training apparatus body 20 by an attachment device 55. The chin rest means 30 is mounted on the other end of the spring. As is known, different springs may have different spring constants. Different spring constants result in different stiffnesses, which in turn result in different resistances. Thus, the resistance of the training device 10 can be adjusted by selecting a spring with a particular spring constant, i.e., stiffness.

[0035] According to another embodiment, the training means 50 may include an elastomeric member, such as a silicone block. Depending on the size, shape, stiffness, and density of the elastomeric member, the resistance of the training device 10 may be adjusted.

[0036] The training device 10 according to the present disclosure provides improved user comfort. The structure of the training device 10 allows the user to perform swallowing rehabilitation in a comfortable position, such as an upright position. Thus, the user does not need to lie down to perform the training. Furthermore, the provided training device 10 includes a structure having a training device body 20 that does not cover the stoma when in use. This facilitates breathing when using the training device 10 and makes the provided training device 10 suitable for users who have undergone a total laryngectomy. In some embodiments, to further improve user comfort for users with a tracheostoma, the training device 10 may additionally include an opening, such as a hole or fork, in the training device body 20. The opening allows air to flow freely into and out of the tracheostoma through the hole in the training device body 20.

[0037] Furthermore, the chin rest means 30, which can move relative to the training apparatus body 20, allows the user to receive tactile feedback while performing swallowing rehabilitation. Receiving direct feedback while performing swallowing rehabilitation can improve the user experience and motivate the user to continue using the training device 10.

[0038] In some embodiments, the training device 10 may further include a handle 65. The handles 65 may be attached to each end of the curved training device body 20. By providing a handle connecting the outer ends of the training device body 20, the training device body 20 and the handle 65 form a closed loop, thus providing a sturdy and secure structure for the training device 10. With the handle 65 available for a user to grasp while using the training device 10, the training device 10 may also be easier to manipulate and hold in the correct position during training.

[0039] 2a shows the training device 10 in use. In FIG. 2a, a user holds the training device 10 in a starting position, i.e., before swallowing rehabilitation begins. The training device 10 according to this embodiment includes a handle 65 that a user holds during use. As shown in the figure, in the starting position, the chest support plate 23 of the training device main body 20 is placed on the user's chest, and the user's chin is placed on the chin support plate 31.

[0040] One advantage of the training device 10 shown herein is that it can be used for a number of different exercises. The exercises begin from the start position described above, and from this position, a number of different exercises can be performed. Some of these exercises will now be described with reference to Figures 2b-2d.

[0041] FIG. 2b shows a user performing an exercise referred to herein as a "chin-pull resistance exercise." The exercise is performed by using the training device 10 to press the chin down toward the user's chest. The chin rests on the chin rest means 30. As the user presses down on their chin, the chin rest means 30 pivots around the pin 45, causing the chin rest means 30 to move toward the training device main body 20. The final position when the chest rest means 30 is fully pressed toward the training device main body 20 is shown in FIG. 2b. The training means 50 provides resistance, so the user must use force to press down on the chin rest means 30. The purpose of this exercise is to strengthen the muscles that pull the larynx and hyoid bone upward and forward, improving swallowing ability. Chin-pull exercises target the same muscles as the commonly known "Shakia exercise" (also known as "head lift exercise"). In these exercises, the user lies supine and lifts their head to look at their toes. Compared to Shakia training, chin-pull training performed with the training device 10 can be performed in a much more comfortable position, for example, standing. Furthermore, with an interchangeable or adjustable training means 50, the load to which the user is exposed can be known and adjustable.

[0042] Another exercise that can be performed using the training device 10 is shown in FIG. 2c. FIG. 2c illustrates an exercise referred to herein as "jaw opening against resistance." The exercise is performed by depressing the lower jaw toward the training device body 20 of the training device 10. The jaw is placed on the chin rest 30. When the user opens their mouth and depresses the lower jaw, the chin rest 30 pivots around the pin 45, causing the chin rest 30 to move toward the training device body 20. The training device 50 provides resistance, so the user must use force to depress the chin rest 30 with their lower jaw. FIG. 2c illustrates the final position of the jaw opening exercise, i.e., when the lower jaw is fully pressed against the training device body 20. The jaw opening exercise targets the same muscles as the commonly known "Masako technique." The purpose is to improve the movement and muscle strength of the posterior pharyngeal wall during swallowing. This exercise can also improve tongue base movement and increase the muscular pressure generated against food and liquid during swallowing.

[0043] Yet another training that can be performed using the training device 10 is shown in FIG. 2d. FIG. 2d shows a training that can be called "effortful swallowing." This training strengthens tongue base retraction and pharyngeal pressure during swallowing to reduce pharyngeal residue. The purpose of this training is to improve the contact and coordination between the different muscles used during swallowing. As shown in FIG. 2d, this training is performed by pressing the jaw against the chin rest means 30 and then swallowing.

[0044] Taken together, the three aforementioned exercises may target the suprahyoid and infrahyoid muscles for laryngeal elevation, and the sternocleidomastoid and lateral pterygoid muscles for trismus and trismus prevention. Therefore, by using the provided training device 10, anterior tongue strength can be increased, maximum mouth opening can be increased, and muscle mass and strength can be increased. Therefore, the provided training device 10 targets all muscles that a total laryngectomy patient may train. Furthermore, because the load of the training means 50 can be known, it is possible to select a training device 10 with a load appropriate for a particular user and, in some cases, to increase the load as the muscles become stronger.

[0045] Referring now to FIG. 3a, another embodiment of the present disclosure will be described. The training device 10 according to this embodiment is embodied in a manner corresponding to that shown in the previous figures, but with a different structure of the holding means 40. As shown in FIG. 3a, the holding means 40 of the training device 10 includes two slightly curved members. The two curved members are fixed at one end to the training device body 20. The two curved members extend in a direction away from the training device body 20. Each of the two curved members includes a guide track 41 configured to receive the chin rest means 30. FIG. 3b is a perspective view of the training device 10 according to this embodiment. As shown in FIG. 3b, the holding means 40 includes two curved members rigidly attached at one end to the training device body 20. The chin rest means 30 is movably connected to the curved members so that the chin rest means 30 can move within the guide track 41. In some embodiments, the chin rest means 30 may include two engagement means 35. The engagement means 35 may extend radially from the chin rest means 30 and be configured to engage with a guide track of the retaining means 40 such that the engagement means 35 is retained in the guide track during movement of the chin rest means 30.

[0046] FIG. 4 shows the aforementioned embodiment in use. As can be seen from FIG. 4, when a user pushes their chin downward, i.e., toward their chest, the chin rest means 30 slides within the guide track toward the training device body 20. While the chin rest means 30 is being pushed down, the training means 50 creates resistance acting on the chin rest means 30, forcing the user to push harder. As shown in FIG. 4, the chin rest means 30 pivots about a center located on the neck of the user using the training device 10. The described embodiment provides a sturdy and sustainable structure for the training device 10.

[0047] 5a shows a cross-sectional view of a training device 10 for swallowing rehabilitation according to a third embodiment of the present disclosure. The training device 10 shown in FIG. 5a includes an adjustment lever 70 that allows adjustment of the resistance to movement of the chin rest means.

[0048] 5a, training device 10 includes a training device body 20 for supporting device 10 during use. Training device body 20 may have a chest rest plate 23 adapted to engage the chest of a user using training device 10. Chest rest plate 23 may have a pad (not shown), such as pad 25 shown in FIG.

[0049] The training device 10 also includes a chin rest means 30 movably connected to the training device body 20. The chin rest means 30 includes a chin rest plate 31 and a pad (not shown), such as pad 33 shown in FIG. 1. The chin rest means 30 also includes a connecting member 32 connected to the training device body 20. In the embodiment of FIG. 5a, the chin rest means 30 is connected to the training device body 20 via a holding means 40 (shown in FIG. 5b) and a pin 45. The chin rest means 30 is pivotable about the pin 45.

[0050] The training device 10 also includes an adjustment lever 70. The adjustment lever 70 includes an elongate member that is pivotable about an adjustment pin 75. The adjustment lever 70 is connected to the training device body 20 via the holding means 40 and the adjustment pin 75. The adjustment lever 70 includes a roller 80 at one end that contacts the underside of the connecting member 32 of the chin rest means 30. In operation, the chin rest means 30 interacts with the roller 80 such that the adjustment lever 70 pivots about the adjustment pin 75 as the chin rest means 30 moves toward the training device body 20.

[0051] In the embodiment of Figure 5a, the training means 50 is located between the training apparatus body 20 and the adjustment lever 70. The training means 50 may be a compression spring similar to those used in the previous embodiments or an elastomeric member such as a silicone block. As shown in Figure 5a, in some embodiments, the training means 50 is located within the handle 65 of the training device 10.

[0052] A resistance applying mechanism is provided for connecting the adjustment lever 70 to the exercise means 50. The resistance applying mechanism may include a connection element 85, e.g., a wire or cable, connected to the adjustment lever 70 at an end of the adjustment lever 70 opposite the roller 80. The resistance applying mechanism may also include a stop 90, e.g., a spring washer, connected to the other end of the connection element 85. The exercise means 50 is disposed between the lever arm 70 and the stop 90. For example, the connection element 85 may pass through the axis of the exercise means 50. As described with respect to FIG. 5c, the adjustment lever 70, the connection element 85, and the stop 90 are operable to compress the exercise means 50 during operation of the device 10.

[0053] The training device 10 shown in FIG. 5a provides adjustable or variable resistance to movement of the chin rest means 30 toward the training equipment body 20. To achieve this, the pivot position of the adjustment lever 70 is adjustable. As shown in FIG. 5a, the adjustment lever 70 includes a rack 95 configured to receive an adjustment pin 75. The rack 95 includes several adjacent positions for receiving the adjustment pin 75, which define different pivot positions for the adjustment lever 70. The adjustment pin 75 is positioned at one of the positions within the rack 95 and provides a pivot for the adjustment lever 70 about that position. Thus, the pivot position is adjustable along the length of the adjustment lever 70 by movement of the adjustment pin 75 between positions within the rack 95. It will be understood that the pivot position of the adjustment lever 70 may be adjustable in any suitable manner, for example, by a sliding mechanism.

[0054] By adjusting the pivot position of the adjustment lever 70, the resistance provided by the device 10 can be increased or decreased as desired. This is because adjusting the pivot position of the adjustment lever 70 changes the length of the adjustment lever 70 on either side of the pivot. If the adjustment lever 70 has a length x and the distance from one end of the adjustment lever 70 to the pivot position is y, the leverage ratio is defined as y / (xy). Therefore, by changing the pivot position, the distance y and the leverage ratio can be changed without changing the length of the adjustment lever. Therefore, an extendable or retractable lever arm is not required, which may not always be used. This allows for a compact design that can still provide a wide range of resistance to movement of the chin rest means 30 toward the training equipment main body 20.

[0055] Each pivot position can increase or decrease the resistance relative to the adjacent position by a set amount. For example, when the adjustment pin 75 is at the minimum resistance position closest to the exercise means 50, the resistance may be approximately 20 N. Each successive pivot position can increase the resistance by approximately 20 N up to the maximum resistance position furthest from the exercise means 50, where the resistance may be approximately 160 N.

[0056] Fig. 5b shows a perspective view of the training device according to this embodiment. As shown in Fig. 5b, the holding means 40 connects the chin rest means 30 to the training device main body 20 via a pin 45. The holding means 40 also connects the adjustment lever 70 to the training device main body 20 via an adjustment pin 75.

[0057] Also shown in Figure 5b is an adjustment knob 100 that allows movement of adjustment pin 75 between positions within rack 95. Adjustment knob 100 can be rotated to an open position to allow movement of adjustment pin 75 between pivot positions. Adjustment knob 100 can then be rotated to a closed position to lock adjustment pin 75 in place.

[0058] Figure 5b also shows that the connecting member 32 of the chin rest means 30 has a fork-like structure at one end. That is, the connecting member 32 includes a single arm 32a that connects to the chin rest plate 31 and two parallel arms 32b that are connected to the pin 45. This structure allows one end of the adjusting lever 70 to pass between the arms 32b as the adjusting lever 70 pivots about the adjusting pin 75. This will be explained in connection with Figure 5c.

[0059] FIG. 5c shows a cross-sectional view of the aforementioned embodiment in use. When a user presses their chin downward, i.e., toward their chest, the chin rest means 30 pivots about the pin 45. This causes the roller 80 to move along the underside of the arm 32a of the connecting member 32, which in turn causes the adjustment lever 70 to pivot counterclockwise about the adjustment pin 75. Furthermore, the end of the adjustment lever 70 passes upward between the arm 32b of the chin rest means 30, pulling the connection element 85 and the stop 90 upward. This causes compression of the training means 50, providing resistance to the user pressing down on their chin. Thus, the user performs the above-described exercise to train the relevant muscles. As described above, the resistance of the training device 10 can be adjusted by changing the position of the adjustment pin 75.

[0060] In some examples, the training means 50 may include multiple springs, each of which may be individually actuated. The multiple springs may be arranged in a magazine configuration. Each spring may have an 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. By individually actuating the springs, a resistance range of 20 N to 160 N may be achieved.

[0061] FIG. 6 shows the training device 10 in use. In FIG. 6, a user holds the training device 10 in the starting position, i.e., before any swallowing rehabilitation begins. During use, the user holds the handle 65. As shown in FIG. 6, in the starting position, the chest support plate 23 of the training device body 20 rests on the user's chest, and the user's chin rests on the chin support plate 31. The training device 10 can be used for multiple different exercises starting from this starting position.
