Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a rehabilitation device for intelligently simulating swallowing movements. Background Art

[0002] Swallowing dysfunction is a common complication of many diseases, especially in neurological diseases such as stroke, brain trauma, Parkinson's disease, and post-radiotherapy for head and neck tumors. Such disorders seriously affect the patient's nutritional intake and quality of life. Difficulty in swallowing can lead to accidental inhalation of food or liquid into the airway, which can easily cause serious lung infections such as aspiration pneumonia, and can even lead to life-threatening airway obstruction, significantly increasing the patient's risk of death and disability rate, and bringing a heavy medical and nursing burden to the patient's family and society.

[0003] Traditional swallowing rehabilitation training methods have many limitations when dealing with this clinical problem. Manual therapies such as oral muscle training and swallowing training rely on the professional skills and experience of the therapist, and it is difficult to ensure the standardization and accuracy of the training movements. In addition, the intensity and frequency of the training are difficult to accurately quantify, resulting in uneven training results. Although electrical stimulation therapy can activate swallowing-related muscles to a certain extent, the stimulation parameters are fixed and cannot be dynamically adjusted according to the individual swallowing physiological characteristics and real-time feedback of the patient, making it difficult to achieve personalized treatment. More importantly, these traditional methods cannot provide patients with intuitive swallowing movement demonstrations and real-time movement feedback corrections. Patients cannot accurately perceive the correct swallowing pattern during training, which greatly hinders their learning and mastering of swallowing skills, and thus seriously affects the rehabilitation efficiency and final efficacy.

[0004] Therefore, the development of an intelligent swallowing simulation rehabilitation device that integrates precise motion simulation, multi-dimensional data monitoring, personalized program customization and telemedicine support for swallowing training has become an urgent clinical need. By simulating the natural swallowing process of the human body through intelligent means, combining advanced sensing technology to collect the patient's swallowing-related physiological data in real time, using intelligent algorithms to analyze and process the data and generate personalized training plans based on this, and at the same time using human-computer interaction technology and remote communication technology to achieve efficient interaction and remote guidance between patients and equipment, medical staff, it is conducive to providing more efficient, accurate and personalized rehabilitation treatment services for patients with swallowing dysfunction, significantly improving the rehabilitation effect and patient quality of life, and reducing medical costs and social burdens. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a rehabilitation device for intelligently simulating swallowing movements.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0033] In the above description of the present invention, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0035] like Figure 1-6 As shown, an embodiment of the present invention is: an intelligent rehabilitation device for simulating swallowing movements, including a main frame 1, an oral upper and lower jaw occlusion training module 2, a tongue extension and curling guidance training module 3, a throat movement simulation submodule 4, an acceleration sensor 5 and a central control panel 6.

[0036] The main frame 1 is the supporting structure of the entire device. Its skull top limiting claw sleeve 101 is used to be fixed on the top of the patient's skull. The skull side face clamp 102 extends along the side of the patient's face and works together with the side face clamping plate 103 at the lower end to stably wear the device on the patient's head, ensuring that the relative positions of various components are fixed during training and no displacement occurs to affect the training effect.

[0037] The core components of the oral upper and lower jaw occlusion training module 2 include a micro servo motor 201, a reduction gear set 202, a transmission connecting rod 203, a light aluminum alloy upper jaw frame 204 and a light aluminum alloy lower jaw frame 205. The micro servo motor 201 outputs power, and after the speed and torque are adjusted by the reduction gear set 202, the transmission connecting rod 203 drives the light aluminum alloy upper jaw frame 204 and the light aluminum alloy lower jaw frame 205 to open and close, simulating the chewing action of the oral cavity. The light aluminum alloy material not only ensures the structural strength but also reduces the overall weight. The medical grade silicone upper jaw pad 206 and the medical grade silicone lower jaw pad 207 coated on the front edge can effectively protect the patient's oral mucosa and provide a touch that is closer to the real oral environment. The surface electromyography sensor 208 set on the inner side of the upper and lower jaws can collect the electromyographic signals of the chewing muscles during movement, which is used to evaluate the muscle activity state.

[0038] In the tongue extension and curling guidance training module 3, the simulated tongue bracket 301 is fixed to the inner end of the lightweight aluminum alloy mandibular frame 205 and the end is close to the throat. The linear stepper motor 302 controls the extension and contraction movement of the tongue simulation silicone body 306, the root rotation joint motor 303 realizes the left and right rotation of the tongue, the vertical rotation joint motor 304 controls the up and down swing of the tongue, and the end curling joint motor 305 makes the tongue simulation silicone body 306 curl. Through the coordinated work of these four motors, the complex movements of the tongue during swallowing are accurately simulated. The pressure sensor 307 on the surface of the tongue simulation silicone body 306 can sense the pressure changes when it contacts objects or tissues in the oral cavity. The collected data is transmitted to the signal acquisition circuit board 308 at the end of the simulated tongue bracket 301 through the embedded wire for subsequent data processing and analysis.

[0039] One end of the flexible bionic pipe 401 of the throat action simulation submodule 4 is fixedly sleeved on the terminal outlet of the simulated tongue bracket 301, and an electrically controlled telescopic spring 404 is arranged axially inside, and its telescopic strength and frequency are controlled by the central processing unit 601 to simulate the contraction of the throat muscles and push the simulated food mass through the pipe. A throat pressure sensor 403 is fixed on the wall of the flexible bionic pipe 401 to monitor the pressure change of the throat during swallowing, and the flow sensor 402 clamped on the outside measures the speed and flow rate of the simulated food mass passing through the throat, and these data provide important basis for evaluating the swallowing function of the throat.

[0040] The acceleration sensor 5 is fixed on the inner side of the neck plate 9, which is located at the lower end of the side face clamping plate 103. It can collect data on the movement posture changes of the patient's neck during swallowing, such as acceleration information generated by movements such as rotation and tilt of the head, to assist in evaluating the patient's swallowing coordination from another dimension.

[0041] The central control panel 6 is connected to the lower end of the main frame 1 through an elastic connecting belt 7, wherein the central processing unit 601 is the core data processing and control unit of the entire device, receiving data from various sensors, such as the surface electromyography sensor 208 of the upper and lower jaw occlusion training module 2, the pressure sensor 307 of the tongue extension and curling guidance training module 3, the throat pressure sensor 403 and flow sensor 402 of the throat action simulation submodule 4, and the acceleration sensor 5, filtering, noise reduction, feature extraction and other processing of these data, and comparing and analyzing with the preset normal swallowing pattern database, generating control instructions according to the analysis results, controlling the working state of each motor and the electric control extension spring 404, adjusting the simulated swallowing action parameters, so as to realize personalized rehabilitation training. The human-computer interaction module 602 includes a touch display screen and a voice prompt and interaction unit, the touch display screen is used to input patient information, select training mode and parameters, display training progress, physiological data feedback and training result evaluation report, etc.; the voice prompt and interaction unit can send voice prompt information to guide patient training, and at the same time has a voice recognition function, and can receive patient voice instructions for operation. The data storage and transmission module 603 uses a large-capacity storage medium to store patient personal information, training history records, normal swallowing pattern database, equipment operation log and other data, and has wired and wireless data transmission functions. It can upload training data to a remote medical server or a medical staff mobile terminal device, and receive updated data from the server, such as database updates or software upgrade information.

[0042] When implementing this embodiment, the following steps are performed:

[0043] Wearing the device

[0044] First, the skull top limiting claw sleeve 101 of the main frame 1 is placed above the patient's head to make it naturally fit the head contour and provide stable support. Then the skull side face clip 102 is gently placed along the side of the face to make it closely contact with the side of the face but not too oppressive.

[0045] Adjust the position of the side face clamping plate 103 so that it fits under the face, and wear the device firmly on the head by adjusting the fixing devices (such as adjustable buckles or bandages) on the side face clamping plate 103 and the side face clamping plate 103. Ensure that the device does not shake or move during the entire training process to ensure that each module can accurately collect data and perform simulated actions.

[0046] Training parameter settings

[0047] After turning on the device, the patient's personal information, such as name, age, gender, disease diagnosis and other detailed information, is input through the touch screen of the human-computer interaction module 602.

[0048] According to the patient's specific condition and physical condition, select the appropriate initial training mode, for example, the basic swallowing training mode is suitable for patients with mild swallowing dysfunction, and the advanced swallowing training mode is for patients who have a certain swallowing foundation but still need further rehabilitation training; and set corresponding training parameters, such as simulated food texture (softer jelly, pudding and other different difficulty levels can be selected), swallowing speed (generally adjusted between 0.1-2 seconds / time), strength (moderate or set according to the actual situation of the patient), etc. These initial setting information will be stored in the data storage and transmission module 603 as the starting parameters of this training, providing basic data support for the dynamic adjustment of the training plan.

[0049] Oral movement simulation training

[0050] Before the oral upper and lower jaw occlusion training module 2 is started, the central processing unit 601 sends an initialization instruction to the micro servo motor 201 according to the preset training mode and parameters. The micro servo motor 201 outputs power according to the instruction, and transmits it to the transmission connecting rod 203 after precise deceleration by the reduction gear set 202. The transmission connecting rod 203 drives the lightweight aluminum alloy upper jaw frame 204 and the lightweight aluminum alloy lower jaw frame 205 to open and close through the ball joint, so as to achieve the initial oral opening and closing angle setting, for example, setting it to simulate the oral opening degree in the natural relaxation state.

[0051] When the chewing action simulation begins, the central processing unit 601 controls the speed and direction of the micro servo motor 201 according to the selected simulated food texture (such as hard food, soft food, etc.) and training requirements, and then accurately adjusts the opening and closing angle and speed of the upper and lower jaws. For example, for simulating chewing hard food, the opening and closing angle range of the upper and lower jaws can be set to a larger value (such as 20-35 degrees), and the opening and closing speed is relatively slow (such as 0.5-2 seconds / time) to enhance the training intensity of the oral muscles; for simulating soft food, a smaller opening and closing angle (such as 10-20 degrees) and a faster speed (such as 0.1-0.5 seconds / time) are set accordingly.

[0052] During the chewing process, the medical grade silicone upper and lower jaw pads 206 coated on the front edges of the upper and lower jaw frames not only protect the patient's oral cavity from damage, but also provide more realistic oral tactile feedback. At the same time, the surface electromyography sensor 208 located on the inner side of the upper and lower jaws collects the electromyographic signals of the masticatory muscles in real time, and these signals are sent to the central processing unit 601 via wireless transmission (transferred by the signal processing module 8). The central processing unit 601 analyzes and processes the electromyographic signals, such as extracting characteristic parameters such as the amplitude and frequency of the electromyographic signals, and judging whether the contraction strength and timing of the masticatory muscles meet the normal swallowing mode or the preset training requirements. If an abnormality is found, such as insufficient muscle contraction force or disordered contraction timing, the central processing unit 601 can adjust the control parameters of the micro servo motor 201, such as increasing the motor output torque or changing the time interval of the motor rotation, to guide the patient to perform correct chewing action training.

[0053] Tongue movement simulation training

[0054] The tongue extension and curling guidance training module 3 works in conjunction with the oral upper and lower jaw occlusion training module 2. While the oral opening and closing movements are in progress or at a specific training stage, the central processing unit 601 sends instructions to the various motors on the tongue bracket 301 according to the preset tongue movement pattern. First, the linear stepper motor 302 is started to push the tongue simulation silicone body 306 forward a certain distance (such as 2-5 cm) to roll the simulated food mass into the oral cavity. In this process, the pressure sensor 307 on the surface of the tongue simulation silicone body 306 monitors the pressure when it contacts the food mass or the inside of the oral cavity in real time, and transmits the data to the signal acquisition circuit board 308 at the end of the tongue bracket 301 through the embedded wire, and the signal acquisition circuit board 308 then transmits the data wirelessly to the central processing unit 601.

[0055] Then, the root rotating joint motor 303, the vertical rotating joint motor 304 and the terminal curling joint motor 305 act according to the predetermined order and parameters. The root rotating joint motor 303 controls the tongue simulation silicone body 306 to rotate left and right in the horizontal direction, the vertical rotating joint motor 304 realizes the up and down swing of the tongue in the vertical plane, and the terminal curling joint motor 305 makes the tongue simulation silicone body 306 curl. These motors work together to fully mix the food mass with saliva and push it to the simulated pharynx. The central processing unit 601 continuously adjusts the speed, direction and movement time of each motor according to the data fed back by the pressure sensor 307 on the surface of the tongue simulation silicone body 306 and the preset normal swallowing tongue movement mode to ensure the accuracy and coordination of the tongue movement. For example, if the pressure sensor 307 detects that the pressure in a certain direction of the tongue is insufficient when pushing the food mass, the central processing unit 601 will increase the output power of the corresponding motor accordingly, so that the tongue moves more powerfully in this direction to promote the smooth movement of the food mass to the pharynx.

[0056] Throat movement simulation training

[0057] When the tongue movement pushes the simulated food mass to the entrance of the simulated pipe in the throat (i.e., the connection between the end outlet of the tongue support 301 and the flexible bionic pipe 401), the central processing unit 601 determines the position and state of the food mass based on the oral pressure sensor (located on the inner side of the upper and lower jaws), the tongue pressure sensor 307 and the tongue movement data, and starts the throat movement simulation submodule 4 in a timely manner.

[0058] The central processing unit 601 sends a control signal to the electrically controlled telescopic spring 404 inside the flexible bionic pipe 401 to adjust the spring's telescopic force and frequency. For example, for patients in the initial training or with weak throat muscle function, a smaller spring telescopic force (such as 0.2-1 Newton) and a slower frequency (such as 0.3-0.8 Hz) are set; as the patient's rehabilitation progresses, the force and frequency are gradually increased to simulate the contraction of the throat muscles during normal swallowing. During the spring contraction process, the throat pressure sensor 403 on the wall of the flexible bionic pipe 401 monitors the pressure changes in the pipe in real time, and the flow sensor 402 measures the speed and flow rate of the simulated food mass passing through the throat. These data are sent to the central processing unit 601 via wireless transmission, and the central processing unit 601 judges the contraction function of the patient's throat muscles, the fluency of the swallowing action, and whether there is swallowing disorder through comprehensive analysis of these data. If it is found that the food mass does not pass smoothly through the throat, such as the pressure is too high or the flow is too low, the central processing unit 601 will adjust the control parameters of the electrically controlled telescopic spring 404, such as increasing the spring's telescopic force or speeding up the frequency, to facilitate the smooth passage of the food mass.

[0059] Training data collection and analysis

[0060] During the entire training process, the surface electromyographic sensor 208 continuously collects electromyographic signals of facial masticatory muscles, tongue muscles and other muscles related to swallowing movements. These signals are first amplified and filtered at the sensor end, and then transmitted to the signal processing module 8 inside the side face clamping plate 103 via wireless signals. The signal processing module 8 further processes the electromyographic signals, such as removing noise interference, extracting feature parameters, etc., and then transmits the processed signals to the central processing unit 601.

[0061] The pressure sensors located in the oral cavity (including the pressure sensors on the inner side of the upper and lower jaws and the pressure sensor 307 on the surface of the tongue simulation silicone body 306) and the throat pressure sensor 403 and the flow sensor 402 collect the pressure and flow data of each part in real time. These data are initially processed by the corresponding signal acquisition circuit board (such as the signal acquisition circuit board 308 at the end of the tongue bracket 301) and transmitted to the central processing unit 601 in the form of wireless signals. The central processing unit 601 conducts a comprehensive analysis of all the received data and compares them with the preset normal swallowing pattern database. The normal swallowing pattern database is established through the accumulation of data from a large number of healthy people and patients with different degrees of swallowing disorders during the rehabilitation process. It contains the standard parameter ranges of various swallowing actions at different stages, such as the electromyographic signal characteristics of the muscles during chewing, the pressure change curves of the oral cavity and throat, and the flow curve of food clumps. The central processing unit 601 determines through comparative analysis whether the patient's swallowing action is accurate and coordinated, whether the swallowing force is appropriate, whether the food mass passes smoothly through the throat, etc., and generates a training result evaluation report based on the analysis results, which is stored in the data storage and transmission module 603 and can also be displayed on the touch screen of the human-computer interaction module 602 for the patient or medical staff to view.

[0062] Human-computer interaction and training feedback

[0063] The human-computer interaction module 602 plays an important role in the training process. The touch screen displays the patient's training progress (such as the number of completed training groups and the number of remaining groups), physiological data feedback (such as oral and throat pressure values, flow data, myoelectric signal strength and other information in the form of charts or numerical values) and training result evaluation reports (such as the analysis results of indicators such as the accuracy and coordination of the patient's swallowing movements in the form of text and charts) in real time, allowing patients and medical staff to intuitively understand the training situation.

[0064] The voice prompt and interaction unit synthesizes voice prompt information according to the instructions of the central processing unit 601. Before the training begins, the voice prompts the patient to wear the sensor correctly and adjust the position of the device; during the training process, the real-time voice guides the patient to simulate the swallowing action. When the patient's swallowing action is wrong or does not meet the requirements, the voice prompt corrects the action, such as "Your upper jaw descends too fast, please slow down"; after the training, the voice broadcasts the training results and suggestions, such as "This training is completed, your throat swallowing strength has improved, but the tongue curling action needs to be strengthened." In addition, the voice interaction unit also has a voice recognition function, and the patient can perform some basic operations through voice commands, such as pausing / continuing training, switching training modes, etc., to improve the convenience and humanization of equipment operation.

[0065] Training completion and data transmission

[0066] When the patient completes the scheduled training time or number of training sessions, the device automatically stops training and issues a voice prompt "This training session has ended". At this point, the data storage and transmission module 603 organizes and stores all physiological data collected during this training (including electromyographic signals, pressure sensor data, flow sensor data, acceleration sensor data, etc.), training parameters (training mode, simulated food texture, swallowing speed and strength, etc.), and training result evaluation reports generated by the central processing unit 601, and classifies and archives them according to patient information and training time, and stores them in the device's built-in large-capacity storage medium. Data storage uses classified storage and encryption technology to ensure the security of patient information and data integrity, making it convenient for medical staff to retrieve and analyze patients' rehabilitation training data at any time to develop personalized rehabilitation treatment plans or conduct rehabilitation effect evaluations.

[0067] At the same time, the device uploads this data in real time to the hospital's telemedicine server or the medical staff's mobile terminal device (such as tablets, smart phones, etc.) through wireless transmission functions (such as Wi-Fi or Bluetooth). During the transmission process, the data will be compressed and encrypted to improve transmission efficiency and ensure data security. In this way, even if the medical staff is not with the patient, they can timely grasp the patient's rehabilitation progress through remote data monitoring, which provides the possibility for remote rehabilitation guidance, breaks the limitations of time and space, improves the utilization efficiency of medical resources, enables patients to enjoy professional rehabilitation medical services in home or community environments, and promotes the continuity and comprehensiveness of rehabilitation treatment.

[0068] The technical effects of this embodiment are as follows:

[0069] Accurately simulate swallowing movements

[0070] Through the coordinated work of the oral upper and lower jaw occlusion training module 2, the tongue extension and curling guidance training module 3 and the throat movement simulation submodule 4, the whole process of normal swallowing can be highly restored. From the chewing action of the mouth, the simulation of the opening and closing angles, speed and chewing force of the upper and lower jaws, to the complex multi-degree-of-freedom movement of the tongue, including extension, curling, left and right and up and down swinging, to the simulation of the contraction of the throat muscles to push the food clumps through, all can be accurately reproduced. This allows patients to experience an action experience that is very similar to real swallowing during training, which helps to activate and exercise the muscle groups related to swallowing, and improve muscle strength, coordination and motor control ability. For example, for patients with swallowing disorders caused by damage to the nervous system, this precise simulation can retrain the brain's control signals for swallowing muscles and promote the recovery of neuromuscular function.

[0071] Multi-dimensional data collection and analysis

[0072] Equipped with various types of sensors, such as surface electromyography sensors 208, oral and pharyngeal pressure sensors (including upper and lower jaw inner pressure sensors, tongue simulation silicone body 306 surface pressure sensors 307 and pharyngeal pressure sensors 403), flow sensors 402 and acceleration sensors 5, the physiological data of patients during swallowing can be collected from different angles. These data comprehensively reflect all aspects of the patient's swallowing movements, including muscle activity, pressure changes in the oral cavity and pharynx, flow characteristics of food boluses, and movement postures of the head and neck. Through the comprehensive analysis of these multi-dimensional data by the central processing unit 601 and comparison with the preset normal swallowing pattern database, the degree of swallowing dysfunction, rehabilitation progress and training effect of the patient can be accurately evaluated. For example, by analyzing the characteristic parameters of the electromyographic signal, it can be determined whether the contraction timing and intensity of the masticatory muscles and tongue muscles are normal; according to the pharyngeal pressure and flow data, the contraction function of the pharyngeal muscles and the smoothness of the passage of food boluses can be understood; combined with the acceleration sensor data, the coordinated movement of the patient's head and neck during swallowing can be further evaluated. Based on these precise assessment results, personalized rehabilitation training plans can be developed for patients to improve the targetedness and effectiveness of rehabilitation treatment.

[0073] Personalized rehabilitation training and real-time feedback

[0074] Based on the powerful data processing capability of the central processing unit 601 and the use of the normal swallowing pattern database, personalized rehabilitation training can be achieved according to the specific situation and rehabilitation progress of each patient. During the training process, the central processing unit 601 can monitor the swallowing action of the patient in real time, and adjust the parameters of each training module in time according to the analysis results of the sensor data, such as the speed and direction of the micro servo motor 201 in the upper and lower jaw occlusion training module 2, the motion parameters of each motor in the tongue extension and curling guidance training module 3, and the extension force and frequency of the electric control extension spring 404 in the throat action simulation submodule 4. At the same time, through the voice prompts and interactive functions of the human-computer interaction module 602, the training situation can be fed back to the patient in real time, the wrong actions can be corrected, and the patient can be guided to perform correct swallowing action training. This personalized training and real-time feedback mechanism can enable the patient to understand his or her shortcomings in time during the training process, and make adjustments and improvements according to the guidance of the equipment, which greatly improves the speed at which the patient learns and masters the correct swallowing skills and accelerates the rehabilitation process. For example, if the patient's muscle strength is insufficient during chewing, the device will automatically increase the opening and closing resistance of the upper and lower jaws, and at the same time, voice prompt the patient to increase the intensity of chewing; if the tongue movement is uncoordinated, the movement parameters of the tongue in various directions will be adjusted specifically, and detailed voice guidance will be given to help patients gradually improve the coordination of swallowing movements.

[0075] Telemedicine and data sharing

[0076] The wireless transmission function and data storage management capability of the data storage and transmission module 603 realize data sharing between the device and the telemedicine server or the mobile terminal device of medical staff. Medical staff can view the patient's training data and rehabilitation progress in real time through the telemedicine platform. Whether the patient is training in the rehabilitation department of the hospital or using the equipment for training at home, they can get professional medical guidance in time. This not only facilitates the management and tracking of patients by medical staff and improves the efficiency of medical services, but also enables patients to receive rehabilitation treatment in a wider environment, promoting the continuity and comprehensiveness of rehabilitation treatment. For example, for some patients who live in remote areas or are inconvenient to go to the hospital frequently due to physical reasons, they can train at home according to the training plan formulated by medical staff through the remote platform, and the training data is uploaded in real time. Medical staff regularly conduct remote evaluation and guidance, and adjust the training plan in time to ensure the effectiveness of rehabilitation treatment. At the same time, the device can also receive updated data from the remote server, such as the update of the normal swallowing pattern database, the upgrade of the device software system, etc., to ensure that the performance of the device and the accuracy of the data are always in the best state, and provide patients with better rehabilitation services.
