Description

Technical Field

[0001] This invention relates to the field of rehabilitation medicine technology, specifically to an integrated device and method for tongue pressure assessment and training of dysphagia after cerebral infarction. Background Technology

[0002] Dysphagia following cerebral infarction is a common clinical functional impairment that severely affects patients' nutritional intake and quality of life. Tongue muscle function assessment and training are core components of dysphagia rehabilitation. Currently, tongue function assessment and training equipment mainly falls into the following two categories:

[0003] The first category is separate devices. Assessment devices primarily use rigid tongue depressor probes (such as the TPM tongue depressor from Jevan International Inc. of Japan), which collect tongue pressure data by inserting a rigid sensor into the oral cavity. Training devices include silicone tongue muscle trainers, pneumatic trainers, etc. These devices require separate operation of the assessment and training modules, necessitating patients to switch between different devices. This process is cumbersome, and the assessment and training data cannot be correlated.

[0004] The second type is the simple integrated device. This type of device typically consists of a rigid shell, built-in pressure sensors, and a spring resistance assembly. It acquires data through tongue pressure sensors and adjusts the spring resistance to achieve training. While this type of device achieves an integrated design, it still suffers from problems such as rigid materials stimulating the oral cavity, low single-point acquisition accuracy, fixed resistance adjustment, and a lack of real-time feedback.

[0005] To address the aforementioned issues, existing technologies have developed tongue pressure assessment and training devices employing flexible sensors. For example, Chinese patent CN219128017U (hereinafter referred to as Prior Artwork Document 1) discloses a flexible tongue pressure sensor that provides precise and comprehensive data acquisition. This sensor comprises a three-layer composite structure consisting of an upper flexible silicone structure, a flexible pressure sensor, and a lower flexible silicone structure. Nine independent force transmission contacts are evenly distributed on the flexible silicone body. It is also equipped with an inflation device, an air bladder, and a one-way valve for adjusting training resistance. This technical solution improves oral comfort through the flexible silicone material and enhances assessment accuracy through a multi-point array sensor, thus compensating to some extent for the shortcomings of traditional rigid sensors.

[0006] Chinese patent CN113812951B (hereinafter referred to as prior art document 2) discloses an array-type flexible tongue pressure acquisition system. This system includes an array-type flexible pressure-sensing membrane, a signal conditioning circuit, an inflatable balloon, a handle, and a smart terminal. Data transmission is achieved via a Bluetooth module, and virtual gamified training is supported. This technical solution adds wireless transmission functionality and smart terminal interaction to the flexible sensing technology, further enhancing the convenience of the device and the user experience.

[0007] Chinese patent application CN121060050A (hereinafter referred to as prior art document 3) discloses an intelligent control method for a tongue pressure feedback training device. This method collects multimodal biosignals such as tongue pressure peak values, laryngeal electromyography signals, and swallowing sound spectrum characteristics. It achieves adaptive feedback through machine learning algorithms and automatically adjusts the training resistance by opening and closing a venting valve. This technical solution introduces the concept of intelligent control and a dynamic adjustment mechanism, demonstrating innovation in training parameter optimization.

[0008] In summary, while existing technologies include individual elements such as flexible sensors, wireless transmission, and intelligent control, none have systematically integrated these elements to form a complete closed-loop system encompassing sensor acquisition, signal processing, resistance adjustment, display feedback, and data transmission. This results in significant shortcomings in existing equipment regarding assessment accuracy, training targeting, ease of operation, and rehabilitation efficiency. There is an urgent need for an innovative tongue pressure assessment and training device that can achieve integrated assessment and training, dynamic closed-loop control, and real-time feedback adjustment. Summary of the Invention

[0009] To address the aforementioned issues, an integrated tongue pressure assessment and training device for dysphagia after cerebral infarction is provided. This device solves the technical problems of separating assessment and training and the inability to dynamically adjust fixed resistance by using flexible array sensing and microprocessor closed-loop control.

[0010] To address the problems of existing technologies, this invention provides an integrated device for tongue pressure assessment and training in post-stroke dysphagia, comprising:

[0022] The elastic airbag unit includes an airbag positioned directly below the sensing and evaluation module.

[0023] In some examples of the present invention, the data processing unit includes a microprocessor and peripheral circuitry.

[0024] In some examples of the present invention, the data transmission unit includes a wireless transmission subunit for realizing wireless data transmission and data synchronization with an external terminal.

[0025] In some examples of the present invention, the resistance training module further includes an aerodynamic control unit.

[0026] The pneumatic control unit includes a miniature air pump and an electromagnetic pressure relief valve, used to control the inflation and deflation of the airbag, thereby adjusting the resistance of the tongue pressing the flexible main body module.

[0027] In some examples of this invention, multi-mode training of the tongue specifically includes:

[0028] In passive stretching mode, the airbag inflates to provide constant resistance, and the patient performs stretching exercises by pressing with their tongue to improve the flexibility of the tongue muscles.

[0029] In the active resistance mode, the airbag resistance is dynamically adjusted, and the patient needs to use their tongue to resist the changing resistance, thereby strengthening the tongue muscles.

[0030] In the rhythmic training mode, the airbag inflates and deflates according to a preset rhythm, and the patient follows the rhythm to train the tongue muscles and improve tongue muscle coordination.

[0031] A method for tongue pressure assessment and training in patients with dysphagia after stroke involves using an integrated device for tongue pressure assessment and training in patients with dysphagia after stroke, specifically including the following steps:

[0032] Step S1: Equipment initialization and preparation.

[0033] This includes device power-on, Bluetooth pairing and connection, patient information entry, and training mode selection;

[0034] Step S2, tongue pressure assessment,

[0035] The patient takes the flexible main body module into their mouth, presses the flexible main body with their tongue, the sensor assessment module collects the pressure signal, and the control feedback module processes the data and displays the assessment results.

[0036] Step S3: Execute training mode.

[0037] Depending on the selected training mode, the device automatically adjusts the hand pressure resistance to train the patient's tongue muscles, thus achieving personalized rehabilitation training.

[0038] Step S4: Data recording and report generation.

[0039] The data processing unit stores the evaluation and training data, making it easy to query and compare historical data.

[0040] The advantages of this invention compared to the prior art are:

[0041] (1) Improve assessment accuracy and training relevance

[0042] This invention utilizes an eight-channel flexible array pressure sensor to achieve multi-point synchronous data acquisition, comprehensively capturing force distribution data across all regions of the tongue. Compared to traditional single-point acquisition methods, this significantly reduces assessment errors caused by contact deviations. A microprocessor analyzes the assessment data in real time, automatically identifying areas of tongue muscle imbalance and dynamically adjusting training plans and resistance parameters accordingly. This enables truly personalized and targeted training, significantly improving the accuracy and effectiveness of rehabilitation training.

[0043] (2) Realize dynamic closed-loop control and intelligent feedback

[0044] This invention constructs a complete closed-loop control system from sensor acquisition, signal processing, resistance adjustment to display feedback. The microprocessor automatically controls the airbag resistance based on real-time tongue pressure data, achieving dynamic adaptation to training difficulty. The OLED screen displays tongue pressure values, distribution curves, and training progress in real time. Combined with the vibration feedback mechanism, this allows patients to intuitively understand their training status and autonomously adjust their force application, significantly improving training initiative and compliance.

[0045] (3) Simplify the operation process and enhance portability

[0046] This invention integrates assessment and training functions, eliminating the need for patients to switch between different devices and significantly simplifying the operation process. Bluetooth wireless transmission eliminates the constraints of wired connections, and with a 3.7V lithium battery power supply, patients can independently complete training at home, greatly improving the device's ease of use and portability. Multi-mode training integration (passive stretching, active resistance, and rhythmic training) is achieved through the same airbag and vibration motor, further simplifying the device structure and operation steps.

[0047] (4) Promote doctor-patient collaboration and rehabilitation management

[0048] This invention synchronizes real-time tongue pressure data to the doctor's terminal via a Bluetooth module, allowing the doctor to remotely monitor the patient's training process and rehabilitation progress, and adjust the training plan accordingly. The complete data recording and rehabilitation record functions provide objective evidence for clinical evaluation and efficacy analysis, helping to build a scientific rehabilitation management system, achieving seamless integration from in-hospital treatment to home rehabilitation, and comprehensively improving the systematicness and continuity of rehabilitation treatment. Attached Figure Description

[0049] Figure 1 This is a flowchart of a method for tongue pressure assessment training for dysphagia after cerebral infarction, according to the present invention. Detailed Implementation

[0050] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0051] An integrated device for tongue pressure assessment and training in post-stroke dysphagia includes:

[0052] The flexible main body module includes a flexible body made of medical-grade flexible silicone, which is arc-shaped to fit the contours of the hard palate and tongue, and has a reserved installation cavity inside.

[0053] The sensing and evaluation module is attached to the upper wall of the installation chamber and is used to collect the pressure signal generated by tongue pressing.

[0054] The resistance training module, located within the mounting chamber and below the sensing and evaluation module, is used to adjust the tongue muscle resistance for performing multimodal training of the tongue muscles.

[0055] A control feedback module, located at the end of the flexible main body module, includes:

[0056] The data processing unit is used to receive the pressure signals collected by the sensing and evaluation module, process and analyze them in real time, and automatically control the resistance parameters of the resistance training module based on the processing results.

[0057] The interactive display unit shows tongue pressure data, training progress, and distribution curves in real time.

[0058] The data transmission unit is used to synchronize data to external terminals to achieve dynamic closed-loop control that integrates evaluation and training.

[0059] The power supply unit provides power to the sensing evaluation module, resistance training module, and control feedback module.

[0060] Specifically, the flexible main body module is integrally molded from medical-grade flexible silicone material, with an overall arc-shaped plate structure. Its curvature design is based on the anatomical characteristics of the human oral cavity, allowing it to closely conform to the contours of the hard palate and tongue. The flexible main body is 70mm long, 30mm wide, and 15mm high. Multiple installation chambers are pre-drilled inside the flexible main body to accommodate components such as flexible pressure sensors, elastic airbags, and flexible wires. These components are fixed to the interior of the flexible main body using medical adhesive. The outer surface of the flexible main body is smooth and without sharp edges to avoid irritating the oral mucosa. It has an IP67 waterproof rating and supports high-temperature sterilization and repeated use. One end of the flexible main body has a control box connection interface, while the other end is a free end, facilitating patient insertion and operation.

[0061] In some examples of the present invention, the sensing evaluation module includes pressure sensors arranged in a matrix within the mounting chamber.

[0062] In some examples of the present invention, the pressure sensor is a flexible pressure sensor, and the surface of the pressure sensor is covered with a protective film.

[0063] Specifically, the sensing and evaluation module includes eight FSR402 flexible pressure sensors arranged in a 2×4 matrix, evenly distributed on the inner surface of the flexible main body. Each sensor has a diameter of 4mm, and the spacing between sensors is 5mm. Sensors S1 to S4 are located in the first row, and sensors S5 to S8 are located in the second row, forming eight detection areas. Each flexible pressure sensor has a range of 0-50kPa and an accuracy of ±0.5kPa. The sensors are electrically connected to the control feedback module via flexible wires with a lead diameter of 0.3mm. When the patient's tongue presses against the flexible main body module, the flexible pressure sensor converts the pressure signal into an electrical signal, which is transmitted to the control feedback module for data processing via the flexible wires. The surface of the flexible pressure sensor is covered with a protective film and sealed with medical adhesive to ensure waterproof performance.

[0064] In some examples of the present invention, the resistance training module includes an elastic airbag unit, the elastic airbag unit including an airbag disposed close to the lower part of the sensing evaluation module.

[0065] Furthermore, the airbag is made of flexible silicone material, and the airbag is filled with elastic aerogel.

[0066] Specifically, an air bladder filled with a flexible material made of elastic aerogel ensures even force distribution during inflation. The air bladder is elliptical, 40mm long and 20mm wide, with a ring-shaped sealing structure at the edges to prevent gas leakage. The air bladder is 3mm thick in its natural state and reaches a maximum thickness of 7mm when inflated, providing a resistance range of 1-10N. The air bladder is located inside the flexible main module, directly beneath the flexible pressure sensor. When the patient presses their tongue against the flexible main module, they directly contact the air bladder and feel the resistance.

[0067] In some examples of the present invention, the resistance training module further includes a pneumatic control unit, which includes a micro air pump and an electromagnetic pressure relief valve for controlling the inflation and deflation of the airbag to adjust the resistance of the tongue pressing the flexible main body module.

[0068] The pneumatic control unit comprises two components: a miniature air pump and an electromagnetic pressure relief valve. The miniature air pump is a miniature cuboid structure, 8mm long, 6mm wide, and 4mm high. It connects to the elastic airbag via an inflation tube, receives control signals from the data processing unit, and inflates the airbag to increase resistance. The electromagnetic pressure relief valve is a circular valve with a diameter of 3mm, connected to both the air pump and the airbag. It receives control signals from the data processing unit, opens the valve to release gas from the airbag, causing it to contract and reduce resistance. The coordinated operation of the air pump and pressure relief valve is automatically controlled by the data processing unit based on real-time tongue pressure data and training modes, achieving dynamic and precise adjustment of resistance.

[0069] In some examples of the present invention, the data processing unit includes a microprocessor and peripheral circuitry.

[0070] Specifically, the data processing unit consists of an STM32F103 microprocessor and its peripheral circuitry. The microprocessor is a rectangular chip, 12mm long, 8mm wide, and 3mm high, installed inside the control box at the rear of the flexible main module. The microprocessor connects to eight flexible pressure sensors via a signal processing board, receiving electrical signals from the sensors, performing analog-to-digital signal conversion, filtering, and pressure value calculation. The microprocessor incorporates a tongue pressure assessment algorithm, capable of calculating real-time tongue pressure values, average pressure, and tongue pressure values ​​for each zone, plotting pressure distribution curves, and generating control commands based on training requirements, which are then sent to the air pump and pressure relief valve in the resistance training module. The peripheral circuitry is used to drive the air pump and electromagnetic pressure relief valve, as well as for voltage conversion.

[0071] In some examples of the present invention, the data transmission unit includes a wireless transmission subunit for realizing wireless data transmission and data synchronization with an external terminal.

[0072] Specifically, the data transmission unit uses an HC-05 Bluetooth module, integrated inside the control box located at the rear of the flexible main module, and connected to the data processing unit. The Bluetooth module supports the Bluetooth 5.0 protocol, ensuring stable and reliable data transmission, and can transmit tongue pressure assessment data, training progress, historical records, and other information to a tablet or doctor's terminal in real time. The Bluetooth device is named ReXSY-1 / 2 and supports pairing and data synchronization. Wireless Bluetooth transmission eliminates the constraints of traditional wired devices, improving ease of use and training adherence.

[0073] In some examples of the present invention, the display interaction unit includes a display screen, a power switch, and a mode switching button.

[0074] Specifically, the display and interaction unit includes a 1.3-inch OLED display, a power switch, and a mode switching button. The OLED display, mounted on the surface of the control box, is 15mm long and 10mm wide, and can display real-time information such as current tongue pressure value, target pressure threshold, average pressure, pressure distribution curve, and training progress. The power switch (which may include a power indicator light) is a circular button with a diameter of 4mm, used to control the device's on / off state; when on, the power indicator light is solid green. The mode switching button, also a circular button with a diameter of 4mm, is used to switch between passive stretching, active resistance, and rhythmic training modes. The human-computer interaction design of the display and mode switching button is simple and intuitive, facilitating independent training by the patient.

[0075] In some examples of the present invention, the power supply unit includes a lithium battery and a power interface.

[0076] Specifically, the power supply unit includes a 3.7V lithium battery and a charging interface. The lithium battery has a rectangular structure, measuring 15mm in length, 8mm in width, and 3mm in height, with a capacity sufficient to support continuous operation for over 4 hours, meeting the needs of a single training session. The charging interface is a rectangular USB port (or Type-C port), 6mm wide and 3mm high, mounted on the surface of the control box, and supports USB charging. The device must not be used while charging or while powered on to ensure safety. The design of the lithium battery and charging interface ensures both portability and long battery life.

[0077] In some examples of this invention, multi-mode training of the tongue specifically includes:

[0078] In passive stretching mode, the airbag inflates to provide constant resistance, and the patient performs stretching exercises by pressing with their tongue, improving the flexibility of the tongue muscles.

[0079] Specifically, in passive stretching mode, a microprocessor controls a miniature air pump to inflate an elastic bladder to a predetermined thickness, providing constant resistance within the range of 1-10N. Following the instructions on the display screen, the patient continuously presses the bladder with their tongue, feeling the resistance, maintaining the pressure for a certain period, then releasing, and repeating the process. Through continuous pressure-relaxation training, the tongue muscles are stretched, improving their flexibility and range of motion. The display screen shows the current tongue pressure and target pressure in real time, guiding the patient to control the intensity of their force.

[0080] In the active resistance mode, the airbag resistance is dynamically adjusted, and the patient needs to use their tongue to resist the changing resistance, thereby strengthening the tongue muscles.

[0081] Specifically, in active resistance mode, the microprocessor dynamically adjusts the airbag resistance based on real-time tongue pressure data and the target pressure threshold. When the patient's tongue pressure reaches the target threshold, the microprocessor controls the air pump to inflate, increasing resistance and raising the training difficulty; when the patient's tongue pressure falls below the target threshold, the microprocessor controls the pressure relief valve to deflate, reducing resistance and lowering the training difficulty. The patient needs to continuously adjust their tongue muscle exertion to counteract the changing resistance, thereby strengthening their tongue muscles. The display shows the current tongue pressure and target pressure in real time, guiding the patient to adjust their exertion. This mode achieves personalized difficulty adaptation through dynamic closed-loop control, improving the targeting and efficiency of training.

[0082] In the rhythmic training mode, the airbag inflates and deflates according to a preset rhythm, and the patient follows the rhythm to train the tongue muscles and improve tongue muscle coordination.

[0083] Specifically, in rhythmic training mode, the microprocessor controls the air pump to inflate and the pressure relief valve to deflate according to a preset rhythm and frequency, causing the air bladder to expand and contract rhythmically. Patients follow the rhythmic changes of the air bladder to train the contraction and relaxation of their tongue muscles, improving tongue muscle coordination and rhythmic awareness. The display screen shows rhythmic prompts, guiding patients to train in accordance with the air bladder's rhythm. The microprocessor can also provide vibration feedback to patients, enhancing the interactivity and enjoyment of the training and improving patient compliance.

[0084] A method for tongue pressure assessment and training in patients with dysphagia after stroke involves using an integrated device for tongue pressure assessment and training in patients with dysphagia after stroke, specifically including the following steps:

[0085] Step S1: Equipment initialization and preparation.

[0086] This includes device power-on, Bluetooth pairing and connection, patient information entry, and training mode selection.

[0087] Specifically, before starting use, the device must first be initialized and prepared. The patient or operator presses the power switch on the control box; the device will turn on, and the power indicator light will remain solid green, indicating normal startup. Next, turn on the Bluetooth function of the tablet or doctor's terminal, locate the Bluetooth device named "ReXSY-1 / 2" in the Bluetooth device list, and pair and connect. After successful connection, open the pre-installed "ReXSY Tongue Pressure Assessment and Training System" software on the tablet, log in to the doctor's account, and enter the patient's basic information, including patient name, age, gender, and medical history. Based on the patient's rehabilitation needs, select the training mode in the software interface, including passive stretching mode, active resistance mode, or rhythmic training mode, and set training parameters, such as training duration and target pressure threshold. After completing the device initialization and preparation, the device enters standby mode, waiting for the patient to begin assessment or training.

[0088] Step S2, tongue pressure assessment,

[0089] The patient places the flexible main body module under their mouth, presses the flexible main body with their tongue, the sensing and assessment module collects the pressure signal, and the control feedback module processes the data and displays the assessment results.

[0090] The patient assumes a seated position, cleans their mouth, and places the flexible main module in their mouth. The curved structure of the flexible module conforms to the hard palate and tongue, with the tip of the tongue lightly touching the hard palate markings. Following instructions, the patient quickly applies maximum pressure to the sensor three times consecutively. The eight flexible pressure sensors in the sensing and assessment module convert the pressure signal generated by the tongue press into an electrical signal, which is transmitted to the data processing unit via flexible wires. The data processing unit filters, amplifies, and performs analog-to-digital conversion on the signal, calculating the real-time tongue pressure value, average pressure, and tongue pressure values ​​for each zone, and plotting a pressure distribution curve. The OLED display screen of the display and interaction unit shows the current tongue pressure value, average pressure, and pressure distribution curve in real time. Simultaneously, the data transmission unit synchronizes the assessment data to the doctor's terminal software system via Bluetooth. Based on the assessment results, the doctor understands the patient's tongue muscle strength and swallowing function status, providing a basis for developing a personalized training plan.

[0091] Furthermore, step S2 includes:

[0092] Step S2.1: Sensor signal acquisition,

[0093] Eight flexible pressure sensors collect pressure signals generated by tongue pressing in real time and convert pressure changes into electrical signals.

[0094] Specifically, when the patient presses their tongue against the sensor area on the inner side of the flexible sensor body, eight flexible pressure sensors (S1 to S8) sense the pressure changes in the corresponding areas. The sensors are FSR402 flexible pressure sensors with a range of 0-50 kPa and an accuracy of ±0.5 kPa. The sensors convert the sensed pressure changes into resistance changes, which are then converted into corresponding voltage signals, forming analog electrical signals. The sensors are arranged in a 2×4 matrix, covering the anterior, middle, and posterior regions of the tongue. Each region is further divided into left, middle, and right partitions, forming nine detection areas. This enables multi-point synchronous acquisition of tongue pressure, improving the accuracy and comprehensiveness of the assessment.

[0095] Step S2.2: Signal processing and analysis.

[0096] The data processing unit processes and calculates the collected electrical signals to generate tongue pressure assessment results.

[0097] Specifically, the STM32F103 microprocessor in the data processing unit receives analog electrical signals from eight sensors. It first filters these signals to remove noise interference, then amplifies and performs analog-to-digital conversion, transforming the analog signals into digital signals. Using a built-in pressure-to-voltage conversion algorithm, the microprocessor converts the digital signals into pressure values, calculating real-time tongue pressure, average pressure, and pressure values ​​for each tongue zone. Based on the pressure data from the nine zones, the microprocessor also plots pressure distribution curves to analyze the force distribution in different areas of the tongue. The calculation results and evaluation reports are stored in the device's memory in real time and transmitted to the doctor's terminal via Bluetooth for reference and analysis.

[0098] Step S2.3: Result display and synchronization.

[0099] The display and interaction unit shows the evaluation results, and the data transmission unit synchronizes the data to the doctor's terminal.

[0100] The 1.3-inch OLED display of the interactive unit shows the assessment results in real time, including the current tongue pressure value, average pressure, and pressure distribution curve. The display uses high-contrast OLED technology, providing clear and easy viewing for both patients and doctors. Simultaneously, the HC-05 Bluetooth module of the data transmission unit synchronizes the assessment data to the doctor's tablet or computer in real time. After receiving the data, the software system on the doctor's terminal generates a tongue pressure assessment report, including the tongue pressure value, average pressure, zoned tongue pressure values, and pressure distribution curve, for the doctor's reference and to provide a basis for developing personalized training programs.

[0101] Step S3: Execute training mode.

[0102] Depending on the selected training mode, the device automatically adjusts the hand pressure resistance, allowing the patient to perform tongue muscle training and achieve personalized rehabilitation training.

[0103] Specifically, based on the training mode selected in step S1, the device enters the training mode and executes the steps. The doctor sets the target pressure threshold and training duration on the software interface. The microprocessor automatically controls the resistance training module to adjust the airbag resistance based on the set parameters and the evaluation results from step S2. The patient performs tongue muscle training according to the instructions on the display screen, pressing the airbag against the resistance with their tongue. The display screen shows the current tongue pressure and the target pressure threshold in real time, guiding the patient to adjust their force. The microprocessor monitors tongue pressure data in real time. When the patient's tongue pressure reaches or exceeds the target threshold, it automatically increases the resistance to increase the training difficulty; when the patient's tongue pressure is below the target threshold, it automatically decreases the resistance to reduce the training difficulty, achieving dynamic closed-loop control. After training, the microprocessor records the training data, including training duration, tongue pressure curve, and number of times the target was achieved, and transmits it to the doctor's terminal via Bluetooth to generate a training report.

[0104] Step S4: Data recording and report generation.

[0105] The data processing unit stores the evaluation and training data, making it easy to query and compare historical data.

[0106] Specifically, the microprocessor has built-in memory capable of storing data records from multiple assessments and training sessions. After each assessment and training session, the microprocessor stores the data in timestamp order, including the assessment date, assessment parameters, assessment results, training date, training mode, training duration, training parameters, and training results. The stored data can be viewed via buttons, allowing patients and doctors to easily understand the rehabilitation progress. Local data storage supports long-term data retention; data will not be lost even if the device is powered off or the battery is replaced, ensuring data integrity and continuity.

[0107] Furthermore, step S4 includes:

[0108] Step S4.1: Local data storage. The microprocessor stores the evaluation and training data in the device's memory for easy historical data retrieval and comparison.

[0109] Specifically, the microprocessor has built-in memory capable of storing data records from multiple assessments and training sessions. After each assessment and training session, the microprocessor stores the data in timestamp order, including the assessment date, assessment parameters, assessment results, training date, training mode, training duration, training parameters, and training results. The stored data can be viewed via buttons, allowing patients and doctors to easily understand the rehabilitation progress. Local data storage supports long-term data retention; data will not be lost even if the device is powered off or the battery is replaced, ensuring data integrity and continuity.

[0110] Step S4.2: Data synchronization and cloud backup.

[0111] The device synchronizes data to the doctor's terminal via Bluetooth and uploads it to a cloud database for backup.

[0112] Specifically, the Bluetooth module of the data transmission unit synchronizes the evaluation and training data stored in the device to the doctor's tablet or computer in real time. Upon receiving the data, the doctor's terminal software system automatically uploads it to a cloud database for backup. The cloud database supports multi-center data management, allowing doctors at different centers to share data, facilitating multi-center research and remote collaboration. Cloud backup ensures data security and traceability; even if the device is lost or damaged, the data can be recovered from the cloud. The cloud data supports big data analytics and machine learning algorithms, providing data support for personalized and precise rehabilitation.

[0113] Step S4.3: Report generation and export.

[0114] The terminal's software system generates evaluation and training reports based on synchronized data, and supports exporting and printing.

[0115] Specifically, the terminal's software system automatically generates tongue pressure assessment reports and training record reports based on synchronized data. The tongue pressure assessment report includes patient basic information, assessment date, assessment parameters, real-time tongue pressure values, average pressure, tongue pressure values ​​for each zone, pressure distribution curve, assessment conclusions, and recommendations. The training record report includes patient basic information, training date, training mode, training duration, training parameters, real-time tongue pressure curve, number of times the target was achieved, average tongue pressure, training summary, and recommendations. The reports support exporting and printing in PDF format for easy archiving and sharing. Doctors can analyze the patient's rehabilitation progress based on the reports, adjust the training plan, and achieve precise rehabilitation management.

[0116] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
