Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a swallowing function rehabilitation training device for stroke patients. Background Technology

[0002] Counteracting mandibular swallowing (CTAR) is a classic rehabilitation intervention for pharyngeal swallowing disorders after stroke. Its core training principle is to guide the patient to actively exert force with the mandible to resist external resistance and simultaneously complete the swallowing action. It specifically strengthens the muscle strength of the suprahyoid muscles, such as the anterior belly of the digastric muscle, the mylohyoid muscle, and the geniohyoid muscle, effectively improving the elevation and anterior movement of the laryngeal complex, promoting the full relaxation and opening of the upper esophageal sphincter (UES), improving the swallowing airway protection mechanism, and reducing the risk of swallowing aspiration and aspiration pneumonia. It is a core rehabilitation method for improving pharyngeal swallowing function deficits in stroke patients.

[0003] Currently, clinical CTAR training relies entirely on manual manipulation by therapists, and existing swallowing rehabilitation equipment lacks standardized, mechanized CTAR resistance training functions. This results in numerous inherent defects in this rehabilitation method during clinical applications and home rehabilitation scenarios, as follows: First, the intensity of resistance training cannot be quantified and cannot be progressively standardized. Current manual training methods rely entirely on therapists manually applying resistance, with the resistance level depending entirely on the operator's subjective experience. There are no standardized quantitative criteria, making it impossible to match precise resistance parameters based on the patient's muscle strength. This easily leads to resistance mismatch during training: insufficient resistance when the patient's muscle strength is high, resulting in a training load that does not meet rehabilitation requirements; excessive resistance when the patient's muscle strength is low, easily inducing compensatory movements such as neck shrugging and head tilting backward, not only significantly reducing the training effect but also potentially solidifying abnormal swallowing patterns. Secondly, the evaluation of training effectiveness is highly subjective and lacks objective quantitative criteria. Currently, clinical practice relies solely on therapists' visual observation of the patient's Adam's apple elevation height and duration of movement, which cannot accurately identify the true movement state of the hyoid-larynx complex during swallowing. It is difficult to distinguish between effective, genuine laryngeal elevation movements and ineffective movements involving simple jaw exertion or neck and somatic compensation, leading to significant biases in training effectiveness evaluation and an inability to accurately determine the patient's rehabilitation progress. Therefore, to address these issues, a swallowing function rehabilitation training device for stroke patients is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a swallowing function rehabilitation training device for stroke patients to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an optional solution of the swallowing function rehabilitation training device for stroke patients described in this invention, the swallowing function rehabilitation training device for stroke patients includes a neck protector, a shoulder support and a shoulder IMU inertial sensing unit. The neck protector is fixedly connected to shoulder support pieces installed on the patient's shoulders on both sides, and each shoulder support piece is equipped with a shoulder IMU inertial sensing unit. A support module is also fixedly connected to one side of the shoulder support piece, and a mandibular resistance training module for the patient to perform resistance training is installed on the top of the support module. The neck protector also has a throat IMU inertial sensing unit inside; A swallowing detection module for obese patients is also installed above the neck protector.

[0006] As an optional embodiment of the swallowing function rehabilitation training device for stroke patients described in this invention, the mandibular resistance training module includes a positioning cylinder, a telescopic device, and a connecting column. The bottom of the positioning cylinder is fixedly connected to the support module. The telescopic device is installed inside the positioning cylinder. The free end of the telescopic device is fixedly connected to the connecting column. The other end of the connecting column is fixedly connected to a support platform. A first pressure sensor is evenly distributed above the support platform. A flexible mandibular support pad is fixedly connected to the other side of the first pressure sensor.

[0007] As an optional embodiment of the swallowing function rehabilitation training device for stroke patients described in this invention, a flexible rubber pad is provided above the flexible mandibular support pad, and the upper part of the flexible mandibular support pad is arc-shaped.

[0008] Currently, clinical CTAR training relies entirely on manual manipulation by therapists, and existing swallowing rehabilitation equipment lacks standardized, mechanized CTAR resistance training functions. This results in numerous inherent defects in this rehabilitation method during clinical applications and home rehabilitation scenarios, as follows: First, the intensity of resistance training cannot be quantified and cannot be progressively standardized. Current manual training methods rely entirely on therapists manually applying resistance, with the resistance level depending entirely on the operator's subjective experience. There are no standardized quantitative criteria, making it impossible to match precise resistance parameters based on the patient's muscle strength. This easily leads to resistance mismatch during training: insufficient resistance when the patient's muscle strength is high, resulting in a training load that does not meet rehabilitation requirements; excessive resistance when the patient's muscle strength is low, easily inducing compensatory movements such as neck shrugging and head tilting backward, not only significantly reducing the training effect but also potentially solidifying abnormal swallowing patterns. Second, the evaluation of training effectiveness is highly subjective and lacks objective quantitative criteria. At present, clinical practice relies solely on therapists' visual observation of the patient's Adam's apple elevation height and duration of the movement. This makes it difficult to accurately identify the true movement state of the hyoid-larynx complex during swallowing, and to distinguish between the patient's effective true laryngeal elevation movement and ineffective movements such as simple jaw exertion and neck and body compensation. This results in significant deviations in the evaluation of training effectiveness and makes it impossible to accurately determine the patient's rehabilitation progress.

[0009] This device is worn around the patient's neck via a neck protector. The laryngeal IMU inertial sensing unit is positioned at the thyroid cartilage, while the shoulder IMU inertial sensing units are integrated within the shoulder supports on both sides. The laryngeal IMU inertial sensing unit collects motion parameters such as the vertical upward displacement of the laryngeal complex and the duration of the movement during swallowing. The shoulder IMU inertial sensing unit collects shoulder motion data as a measurement benchmark. The two sets of IMU sensors work together to perform differential calculations, eliminating measurement interference introduced by trunk swaying and overall head pitching movements, calculating the true upward displacement of the laryngeal complex relative to the thoracic cavity. This quantified laryngeal complex upward displacement parameter enables an objective and accurate assessment of the patient's rehabilitation progress.

[0010] As an optional solution of the swallowing function rehabilitation training device for stroke patients described in this invention, the swallowing detection module for obese patients includes a dental kit, a dental clasp, and a fitting bag. The dental kit has a dental clasp on its upper part, and the fitting bag is fixedly connected to both ends of the dental kit. A waterproof pad is fixedly connected to the bottom of the fitting bag, and a pressure detection mechanism is installed inside the fitting bag. The pressure detection mechanism includes a first and a second flexible plate that are arranged vertically, and a second pressure sensor that is evenly distributed between the first and the second flexible plates.

[0011] In actual training scenarios, for obese patients, the laryngeal IMU inertial sensing unit is attached to the lateral side of the thyroid cartilage in the neck. Due to the loose skin and subcutaneous fat accumulation in the neck, when the laryngeal cartilage body shifts upward, the surface skin and fat layer are prone to shear slippage, causing deviations in the upward elevation amplitude collected by the laryngeal IMU inertial sensing unit. Moreover, such movement deviations are difficult to identify by human visual observation. To address this, this device is equipped with an obese patient swallowing detection module as an auxiliary detection unit. This obese patient swallowing detection module is placed inside the oral cavity, with its palatal apposition pouch attached to the palate. When the patient performs a swallowing action, the tongue squeezes the waterproof pad, and the pressure signal of the swallowing process is collected by the second apposition flexible plate. The quality of swallowing training is judged based on the pressure data.

[0012] As an optional solution of the swallowing function rehabilitation training device for stroke patients described in this invention, the mandibular resistance training module can work in conjunction with the shoulder IMU inertial sensing unit and the laryngeal IMU inertial sensing unit, and adaptively adjust the resistance output intensity of the mandibular resistance training module according to the real-time collected training data to ensure the swallowing training effect.

[0013] As an optional solution of the swallowing function rehabilitation training device for stroke patients described in this invention, the support module includes a fixed seat, a protective sleeve and a rotating seat. One side of the fixed seat is fixedly connected to the shoulder support, and the rotating seat is rotatably connected to the lower side of the fixed seat. A protective sleeve is provided between the fixed seat and the rotating seat. One end of the protective sleeve is fixedly connected to the fixed seat and the other end of the protective sleeve is fixedly connected to the rotating seat. The protective sleeve also has symmetrically arranged support components inside.

[0014] As an optional embodiment of the swallowing function rehabilitation training device for stroke patients described in this invention, a groove for easy passage of pipelines is provided at the bottom of the protective sleeve.

[0015] As an optional solution of the swallowing function rehabilitation training device for stroke patients described in this invention, the support includes a first rotating plate, a second rotating plate and an automatic locking component. One side of the first rotating plate is rotatably connected to the rotating seat, and the other end of the first rotating plate is rotatably connected to the second rotating plate. The other end of the second rotating plate is rotatably connected to the fixed seat. One side of the second rotating plate is fixedly connected to a retractable automatic locking component, which is locked in a groove on the surface of the first rotating plate.

[0016] As an optional embodiment of the swallowing function rehabilitation training device for stroke patients described in this invention, the first rotating plate and the second rotating plate are both arc-shaped, and an arc-shaped groove is provided above the first rotating plate, and one side of the second rotating plate is disposed in the arc-shaped groove.

[0017] To improve the overall stability of the device during operation, the rotating seat drives the first rotating plate and the second rotating plate to unfold. The automatic locking component on the side of the second rotating plate engages in the groove opened in the first rotating plate to complete the automatic locking and fixation. One side of the rotating seat rests against the patient's chest to provide support and limit the upper fixed seat, thereby ensuring that the mandibular resistance training module can stably carry out resistance training.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This device is worn around the patient's neck via a neck protector. The laryngeal IMU inertial sensing unit is positioned at the thyroid cartilage, while the shoulder IMU inertial sensing units are integrated within the shoulder supports on both sides. The laryngeal IMU inertial sensing unit collects motion parameters such as the vertical upward displacement of the laryngeal complex and the duration of the movement during swallowing. The shoulder IMU inertial sensing unit collects shoulder motion data as a measurement benchmark. The two sets of IMU sensors work together to perform differential calculations, eliminating measurement interference introduced by trunk swaying and overall head pitching movements, calculating the true upward displacement of the laryngeal complex relative to the thoracic cavity. This quantified laryngeal complex upward displacement parameter enables an objective and accurate assessment of the patient's rehabilitation progress.

[0019] In actual training scenarios, for obese patients, the laryngeal IMU inertial sensing unit is attached to the lateral side of the thyroid cartilage in the neck. Due to the loose skin and subcutaneous fat accumulation in the neck, when the laryngeal cartilage body shifts upward, the surface skin and fat layer are prone to shear slippage, causing deviations in the upward elevation amplitude collected by the laryngeal IMU inertial sensing unit. Moreover, such movement deviations are difficult to identify by human visual observation. To address this, this device is equipped with an obese patient swallowing detection module as an auxiliary detection unit. This obese patient swallowing detection module is placed inside the oral cavity, with its palatal apposition pouch attached to the palate. When the patient performs a swallowing action, the tongue squeezes the waterproof pad, and the pressure signal of the swallowing process is collected by the second apposition flexible plate. The quality of swallowing training is judged based on the pressure data.

[0020] The mandibular resistance training module can work in conjunction with the shoulder IMU inertial sensing unit and the laryngeal IMU inertial sensing unit. Based on the real-time collected training data, it adaptively adjusts the resistance output intensity of the mandibular resistance training module to ensure the swallowing training effect.

[0021] To improve the overall stability of the device during operation, the rotating seat drives the first rotating plate and the second rotating plate to unfold. The automatic locking component on the side of the second rotating plate engages in the groove opened in the first rotating plate to complete the automatic locking and fixation. One side of the rotating seat rests against the patient's chest to provide support and limit the upper fixed seat, thereby ensuring that the mandibular resistance training module can stably carry out resistance training.

Detailed Implementation

[0024] Example 1: Please refer to Figure 1 , Figure 4 and Figure 5 The present invention provides a technical solution: A rehabilitation training device for swallowing function in stroke patients includes a neck protector 1, a shoulder support 2, and a shoulder IMU inertial sensing unit 3. The neck protector 1 is fixedly connected to the shoulder support 2 installed on the patient's shoulders on both sides, and the shoulder support 2 is equipped with a shoulder IMU inertial sensing unit 3. A support module 4 is also fixedly connected to one side of the shoulder support 2, and a mandibular resistance training module 5 for the patient to perform resistance training is installed on the top of the support module 4. The neck protector 1 also has a throat IMU inertial sensing unit 6 installed inside; A swallowing detection module 7 for obese patients is also installed above the neck protector 1.

[0025] The mandibular resistance training module 5 includes a positioning cylinder 501, a telescopic device 502, and a connecting column 503. The bottom of the positioning cylinder 501 is fixedly connected to the support module 4. The telescopic device 502 is installed inside the positioning cylinder 501. The free end of the telescopic device 502 is fixedly connected to the connecting column 503. The other end of the connecting column 503 is fixedly connected to the support platform 504. The top of the support platform 504 is equipped with uniformly distributed first pressure sensors 505. The other side of the first pressure sensor 505 is fixedly connected to a flexible mandibular support pad 506.

[0026] A flexible rubber pad is provided on the top of the flexible mandibular support pad 506, and the top of the flexible mandibular support pad 506 is arc-shaped.

[0027] Currently, clinical CTAR training relies entirely on manual manipulation by therapists, and existing swallowing rehabilitation equipment lacks standardized, mechanized CTAR resistance training functions. This results in numerous inherent defects in this rehabilitation method during clinical applications and home rehabilitation scenarios, as follows: First, the intensity of resistance training cannot be quantified and cannot be progressively standardized. Current manual training methods rely entirely on therapists manually applying resistance, with the resistance level depending entirely on the operator's subjective experience. There are no standardized quantitative criteria, making it impossible to match precise resistance parameters based on the patient's muscle strength. This easily leads to resistance mismatch during training: insufficient resistance when the patient's muscle strength is high, resulting in a training load that does not meet rehabilitation requirements; excessive resistance when the patient's muscle strength is low, easily inducing compensatory movements such as neck shrugging and head tilting backward, not only significantly reducing the training effect but also potentially solidifying abnormal swallowing patterns. Second, the evaluation of training effectiveness is highly subjective and lacks objective quantitative criteria. At present, clinical practice relies solely on therapists' visual observation of the patient's Adam's apple elevation height and duration of the movement. This makes it difficult to accurately identify the true movement state of the hyoid-larynx complex during swallowing, and to distinguish between the patient's effective true laryngeal elevation movement and ineffective movements such as simple jaw exertion and neck and body compensation. This results in significant deviations in the evaluation of training effectiveness and makes it impossible to accurately determine the patient's rehabilitation progress.

[0028] This device is worn around the patient's neck via a neck protector 1. A laryngeal IMU inertial sensing unit 6 is positioned at the patient's thyroid cartilage, while shoulder IMU inertial sensing units 3 are integrated within the shoulder supports 2 on both sides. The laryngeal IMU inertial sensing unit 6 collects motion parameters such as the vertical upward displacement and duration of the laryngeal complex during swallowing, while the shoulder IMU inertial sensing unit 3 collects shoulder motion data as a measurement benchmark. The two sets of IMU sensors work together to perform differential calculations, eliminating measurement interference introduced by trunk swaying and overall head pitching movements, and calculating the true upward displacement of the laryngeal complex relative to the thoracic cavity. This quantified laryngeal complex upward displacement parameter enables an objective and accurate assessment of the patient's rehabilitation progress.

[0029] The mandibular resistance training module 5 can work in conjunction with the shoulder IMU inertial sensing unit 3 and the laryngeal IMU inertial sensing unit 6, and adaptively adjust the resistance output intensity of the mandibular resistance training module 5 based on the real-time collected training data to ensure the swallowing training effect. Also includes the following: The principle behind the collaborative operation of two sets of IMU sensors to filter overall torso swaying is as follows: When the torso sways, the thorax and larynx undergo completely identical rigid body motion. The two sets of IMU sensors collect almost identical acceleration and displacement components; after differential subtraction, the common components of the overall torso swaying are directly canceled out, leaving only the local motion of the larynx relative to the thorax.

[0030] For example: If the body shakes upwards by 2mm, the IMU inertial sensor unit 6 at the throat will read +2mm, and the IMU inertial sensor unit 3 at the shoulder will also read +2mm; after differential calculation, 2-2=0mm, the overall shaking is filtered out and will not be misinterpreted as throat elevation. Filtering head pitch and rotation interference (head down, head up). Head pitch is the rotation of the head around the cervical spine pivot.

[0031] The laryngeal IMU inertial sensing unit 6 participates in head pitch and rotation along with the skull and larynx; The shoulder IMU inertial sensing unit 3 is fixed to the ribcage and does not participate in head pitch and rotation.

[0032] The algorithm reads the attitude angles (pitch and roll) output by the two IMUs, calculates the relative attitude change of the throat relative to the thorax, and removes the displacement projection component caused by simple head rotation.

[0033] Simple head tilting motion: Only the head angle rotates, and the laryngeal cartilage does not shift upward relative to the rib cage; the algorithm identifies this rotation through posture difference, subtracts the spurious displacement term derived from the rotation, and does not mistake head tilting for laryngeal elevation; What remains after the difference is the actual upward / anterior displacement of the thyroid cartilage relative to the thoracic skeleton and the laryngeal complex, which is a physical quantity that needs to be evaluated in CTAR training. Traditional resistance training involves the patient pushing their jaw downwards against the therapist's hand while swallowing. This strengthens the suprahyoid muscles (anterior belly of the digastric muscle, mylohyoid muscle, and geniohyoid muscle), increases the degree of laryngeal elevation, improves the upward and forward movement of the laryngeal complex, promotes full opening of the upper esophageal sphincter (UES), and reduces aspiration. However, because the therapist's hand is unsupported, it moves with the patient's jaw downwards, resulting in poor resistance training effectiveness. By using a telescopic device 502 to move the connecting column 503 above, which in turn moves the support platform 504 and the flexible jaw support pad 506, positioning them at the patient's jaw, the first pressure sensor 505 can collect pressure data in real time during jaw training. This allows for timely adjustments based on the training progress, ensuring training quality.

[0034] When the training patient is a mildly to moderately obese patient, the obese patient swallowing detection module 7 is an auxiliary compensation method used to assist in the assessment of the distortion of the neck IMU measurement in obese people. It is not a replacement for the laryngeal IMU laryngeal elevation measurement. When the training patient is a severely obese patient, when the laryngeal IMU inertial sensing unit 6 is basically inactive, the obese patient swallowing detection module 7 is upgraded to the main method. The obese patient swallowing detection module 7 is placed in the patient's mouth to detect the pressure of the tongue when the patient swallows to determine the swallowing action. The swallowing training quality is roughly judged by the magnitude of the pressure data.

[0035] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 5 Specifically, the obese patient swallowing detection module 7 includes a dental kit 701, a dental clasp 702, and a fitting bag 703. The dental kit 701 has a dental clasp 702 on its upper part. Both ends of the dental kit 701 are fixedly connected to the fitting bag 703. The bottom of the fitting bag 703 is fixedly connected to a waterproof pad 706. A pressure detection mechanism is installed inside the fitting bag 703. The pressure detection mechanism includes a first flexible plate 704 and a second flexible plate 705 that are distributed vertically, and a second pressure sensor 707 that is evenly distributed between the first flexible plate 704 and the second flexible plate 705.

[0036] In actual training scenarios, for obese patients, the laryngeal IMU inertial sensing unit 6 is attached to the lateral side of the thyroid cartilage in the neck. Due to the loose skin and subcutaneous fat accumulation in the neck, when the laryngeal cartilage body shifts upward, the surface skin and fat layer are prone to shear slippage, causing deviations in the upward elevation amplitude collected by the laryngeal IMU inertial sensing unit 6. Moreover, such movement deviations are difficult to identify by human visual observation. To address this, the device is equipped with an obese patient swallowing detection module 7 as an auxiliary detection unit. This obese patient swallowing detection module 7 is placed inside the oral cavity, with its palatal adhesion pouch 703 adhering to the palate. When the patient performs a swallowing action, the tongue squeezes the waterproof pad 706, and the second flexible plate 705 collects the pressure signal during the swallowing process. The quality of swallowing training is judged based on the pressure data.

[0037] Also includes the following: The dental kit 701 can be installed on the outer side of the upper teeth through the dental clasp 702 and extends to the position of the back molars. At this time, the occlusal capsule 703 is located on the palate. The quality of swallowing training can be detected by the tongue squeezing force during swallowing, which can assist obese people in swallowing rehabilitation training.

[0038] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 2 and Figure 3Specifically, the support module 4 includes a fixed base 401, a protective sleeve 402, and a rotating base 403. One side of the fixed base 401 is fixedly connected to the shoulder support 2, and the rotating base 403 is rotatably connected to the lower side of the fixed base 401. The protective sleeve 402 is provided between the fixed base 401 and the rotating base 403. One end of the protective sleeve 402 is fixedly connected to the fixed base 401, and the other end of the protective sleeve 402 is fixedly connected to the rotating base 403. The protective sleeve 402 also has symmetrically arranged support members inside.

[0039] A cable groove 404 is provided at the bottom of the protective sleeve 402 to facilitate the passage of pipelines.

[0040] The support includes a first rotating plate 405, a second rotating plate 406, and an automatic locking component 407. One side of the first rotating plate 405 is rotatably connected to the rotating seat 403, and the other end of the first rotating plate 405 is rotatably connected to the second rotating plate 406. The other end of the second rotating plate 406 is rotatably connected to the fixed seat 401. One side of the second rotating plate 406 is fixedly connected with a retractable automatic locking component 407, and the automatic locking component 407 is locked in the groove opened on the surface of the first rotating plate 405.

[0041] Both the first rotating plate 405 and the second rotating plate 406 are arc-shaped, and an arc-shaped groove is provided above the first rotating plate 405, while one side of the second rotating plate 406 is located in the arc-shaped groove.

[0042] To improve the overall stability of the device during operation, the rotating seat 403 drives the first rotating plate 405 and the second rotating plate 406 to unfold. The automatic locking component 407 on the side of the second rotating plate 406 is engaged in the groove of the first rotating plate 405 to complete automatic locking and fixation. One side of the rotating seat 403 abuts against the patient's chest to support and limit the upper fixed seat 401, thereby ensuring that the mandibular resistance training module 5 can stably carry out resistance training.

[0043] Also includes the following: A protective sleeve 402 is provided on the outside of the support component to effectively prevent cables and air pipes from being clamped between the fixed base 401 and the rotating base 403, thus preventing the pipelines from being squeezed and damaged, affecting the normal operation of the equipment. Simultaneously, the equipment has a dedicated cable tray 404. When the equipment is in operation, cables and air pipes can be neatly stored inside the cable tray 404, providing protective restraint for the pipelines and ensuring smooth and stable wiring and airflow. At the end of training and when the equipment is being stored, the automatic locking component 407 can be pressed by the protective sleeve 402, causing it to retract and unlock, releasing the locking state of the first rotating plate 405 and the second rotating plate 406. At this time, the first rotating plate 405 and the second rotating plate 406 can be rotated and folded laterally to complete the equipment storage. This lateral folding structure requires no additional installation and storage space, is compact, and easy to store, effectively improving the practicality and portability of the device.
