Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a dysphagia treatment and evaluation system. Background Art

[0002] Dysphagia is a common and important complication of stroke, with an incidence rate as high as 50% to 70%. It often manifests as difficulty swallowing and coughing when eating, which can lead to aspiration, aspiration pneumonia, malnutrition, and even suffocation.

[0003] To date, treatment options for stroke-related dysphagia are limited. Traditional treatments primarily include replacement feeding methods, dietary adjustments, behavioral and postural techniques, peripheral sensorimotor stimulation, or active exercises designed to strengthen the function of selected muscle groups and improve movement time at the onset of swallowing. These methods aim to ensure the safety and adequate food intake of patients experiencing post-stroke dysphagia. Although these methods have played a role in treating stroke-related dysphagia, rapid and effective improvement of stroke-related dysphagia remains difficult based on current results. Therefore, rehabilitation of stroke-related dysphagia remains a major challenge that needs to be addressed in the current rehabilitation field.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0065] Figure 1 This is a schematic diagram of the structure of a swallowing disorder treatment and evaluation system provided in an embodiment of the present application. Figure 1As shown, the swallowing disorder treatment and evaluation system includes an electronic component 100, a telescopic bracket 200, a display 300, a camera component 400 and a control terminal 500. The electronic component 100 includes an electrical stimulation module 101 and an electromyography acquisition module 102; the electrical stimulation module 101 is used to output electrical stimulation to the pharynx, and the electromyography acquisition module 102 is used to collect electromyography signals of the pharynx; the display 300 is installed on the telescopic bracket 200; the camera component 400 is arranged at the upper end of the display 300; and the control terminal 500 is signal-connected to the electronic component 100 and the display 300.

[0066] In this embodiment, the control terminal 500 is used to: in response to the input evaluation signal, control the camera component 400 to start working, control the display 300 to play the guidance video, and control the electromyography acquisition module 102 to start working, and obtain the image data fed in real time by the camera component 400 and the electromyography signal fed by the electromyography acquisition module 102; wherein, the evaluation signal includes a swallowing task, and the guidance video played by the display is determined according to the swallowing task, and the swallowing task includes a drink swallowing task, a shared swallowing task, a food swallowing task, and a custom swallowing task; when a swallowing task is completed, the initial muscle signal is determined based on the electromyography signal fed by the electromyography acquisition module 102, and the muscle strength level is determined according to the initial electromyography signal, and the muscle strength level is displayed through the display 300; the treatment mode is determined according to the muscle strength level; wherein, the treatment mode includes Passive mode, power-assisted mode and active mode; in the passive mode, the control terminal 500 controls the electrical stimulation module 101 to output electrical pulse stimulation in response to the input waveform parameters; in the power-assisted mode, the control terminal 500 controls the electrical stimulation module 101 to output electrical stimulation of a set intensity, and the set intensity is determined according to the muscle strength level; in the active mode, the electrical stimulation module 101 does not output electrical stimulation; when the treatment mode is determined, in response to the input treatment signal, the camera component 400 is controlled to start working, the display 300 is controlled to play the guide video, the electromyography acquisition module 102 is controlled to start working, and the electrical stimulation module 101 is controlled to output corresponding electrical stimulation according to the treatment mode, and the image data fed by the camera component 400 in real time and the electromyography signal fed by the electromyography acquisition module are obtained; wherein, the treatment signal includes a swallowing task.

[0067] In this embodiment, the display 300 is selected as a touch display. When the patient uses the swallowing disorder treatment evaluation system, the patient can send corresponding signal instructions to the control terminal 500 through the display 300 to perform different operations, such as controlling the interruption or start and stop of treatment.

[0068] The following will specifically introduce the treatment and evaluation process of the dysphagia treatment and evaluation system.

[0069] A user module can be configured in the control terminal 500, which is used for user registration and login. Specifically, when the user is not logged in, the swallowing disorder treatment and evaluation system is started, and the home page interface of the display 300 is as follows: Figure 2 As shown. Figure 3 As shown, patients register as users under the guidance of a physician or on behalf of a physician. The information includes name, gender, age, height, weight, swallowing disorder diagnosis, hospitalization number, bed number, admission time, rehabilitation physician, etc. Name, gender, and age are required information and are used for naming treatment reports. Figure 4 As shown in the figure, when a patient uses the swallowing disorder treatment evaluation system for the second time, he only needs to select [User Login] and select the corresponding user name in the login list to complete the login. After the user completes the first registration and the second and subsequent logins, as shown in the figure, Figure 5 and Figure 6 As shown, a welcome message to the user for the first registration and the number of logins will be displayed on the display 300 .

[0070] To effectively assess a patient's swallowing ability before treatment, an assessment interface and animation are designed to guide the patient through a set number of swallowing movements. The myoelectric acquisition module synchronously detects the patient's electromyographic signals during swallowing and wirelessly transmits them to the control terminal. After amplification, filtering, and noise removal, the control terminal extracts features to quantify the patient's muscle activation, which is then used to assess the patient's swallowing ability.

[0071] The evaluation signal obtained by the control terminal includes the muscle group to be evaluated. The physician can select the muscle group to be evaluated or input the muscle group name. The input muscle group name will be retained in the options for direct selection next time. Except for a few fixed muscle groups that cannot be deleted, the rest of the customized muscle groups can also be deleted to make the options simple. (The myoelectric signal image of the muscle group will be determined after the actual measured data is obtained later. If the data is poor and cannot show the regular changes in the myoelectric signal, it will be considered for deletion). Figure 7 As shown in (a) and (b), the default guided animation on the right is drink swallowing. The physician can also select food swallowing animation. There are swallowing animations and custom animations (angiography videos or other videos).

[0072] Click [Re-evaluate] in the interface displayed on the display 300 to restart the evaluation; click [Confirm] to complete the evaluation and display the evaluation results, such as Figure 8 The interface will show the strength level of the two muscles (groups) assessed this time and last time. If no assessment was performed last time, the value will be displayed as 0. A message "Keep up the good work!" will be added as encouragement. Close Figure 8After the pop-up window appears, click [Confirm] or the X in the upper right corner to exit the evaluation interface to complete the pre-treatment evaluation. You can also select [Re-evaluate].

[0073] After the evaluation is completed, treatment will be initiated. The dysphagia treatment evaluation system has three treatment modes.

[0074] (1) Passive mode

[0075] Suitable for patients with dysphagia (muscle strength levels 0-4), this device delivers electrical stimulation to the treatment area to enhance muscle strength. This program-based treatment is more targeted and provides standardized rehabilitation, ensuring greater patient safety and greater convenience for physicians. The waveform parameters of the electrical stimulation in passive mode are adjustable.

[0076] (2) Power-assisted mode

[0077] Suitable for patients with swallowing difficulties of levels 5-9, this device helps patients complete the entire swallowing process independently. It monitors the patient's electromyography in real time and simultaneously delivers electrical stimulation to the treatment area, achieving a perfect combination of active training and electrical stimulation, enhancing exercise effectiveness and boosting recovery confidence. The waveform parameters of the electrical stimulation in assisted mode are adjustable.

[0078] (3) Active mode

[0079] Suitable for patients with mild dysphagia of level 10 or above, this mode does not require electrical stimulation and only relies on visual and auditory stimulation and feedback on the interactive interface to guide patients to actively complete swallowing movements.

[0080] Based on this, the muscle strength level is divided into 0 to 10 levels according to the swallowing muscle strength of the patient and normal people. The system will compare the EMG value assessed before treatment with the normal muscle strength value, and correspond the muscle strength level according to the ratio. For example, if the normal muscle strength is 100mv and the patient's assessment is only 40mv, it is considered to be a muscle strength level 4. Taking into account the stability of the swallowing movement, the myoelectric level is set downward, that is, if the ratio is 25%, it corresponds to level 2. The muscle strength level will automatically give the recommended muscle strength level after the swallowing ability is evaluated. Among them, the passive mode is suitable for patients with muscle strength levels 0-4, the power mode is suitable for patients with muscle strength levels 5-9, and patients with muscle strength levels 10 and higher are suitable for active mode. Muscle strength levels 10 and higher are all displayed as level 10 on the interface.

[0081] In assisted mode, patients cannot swallow on their own. Therefore, assistance levels are established. Once the patient has a certain level of muscle strength, the device will provide the additional muscle force needed to complete the swallowing action. For example, an assistance level of 3 indicates that the patient has a muscle strength level of 7 (70% of the normal EMG value). Once the patient has reached this level, the assistance mode will activate, delivering the corresponding electrical pulse stimulation to the patient. The electrical pulse intensity is equivalent to 30% of the normal EMG value. Similarly, the assistance level is automatically recommended after the swallowing ability assessment. The assistance level is set from 1 to 10, with levels 1-5 corresponding to muscle strength levels 5-9. Taking into account individual patient differences, even with 100% of the normal EMG value, patients may not be able to complete the swallowing action. Therefore, the subsequent levels 6-10 are used to adjust the assistance level according to actual treatment needs. If the assistance level is 3, the electrical stimulation intensity can be selected from 21-30mA. If it exceeds 30mA, it will automatically jump to level 4.

[0082] like Figure 9 As shown, in passive mode, the therapeutic device continuously outputs electrical pulse stimulation according to the waveform parameters set on the interface. If the waveform parameters need to be adjusted, the physician can do so on the interface or through the handle. The interval time and rest time can be set by the physician, or they can be left unset and electrical stimulation will be output continuously. The default values ​​are 10 minutes and 3 minutes respectively. If the interval time is 10 minutes and the rest time is 3 minutes, it means that the patient will start to rest at the 10th minute after the start of treatment, and the rest time will be 3 minutes. A rest pop-up box will appear on the interface to prompt the patient to rest; at the 13th minute, normal treatment will begin; and the patient will rest again at the 23rd minute after the start of treatment, and so on. If the interval time and rest time are not set, the rest pop-up box will not be prompted.

[0083] like Figure 10 As shown, in assisted mode, after the swallowing ability assessment automatically recommends the muscle strength level, or after the automatic recommendation or physician-set assistance level, you can select [Automatic] mode for assisted mode treatment. That is, when the device automatically detects that the patient's muscle strength exceeds the assessed muscle strength level, it automatically and continuously outputs electrical stimulation assistance within the assistance time. You can also select [Manual] mode. The physician can remotely control the handle signal to start and stop the electrical pulse stimulation output based on the patient's swallowing status and swallowing movement performance, regardless of whether the patient's muscle strength reaches the muscle strength level. The handle can also be used to increase or decrease the assistance level (i.e., the amplitude of the electrical pulse stimulation). In [Automatic] mode, the interval time and rest time can be set by the physician. In [Manual] mode, the interval time and rest time cannot be set.

[0084] like Figure 11As shown in the figure, in active mode, the patient completes the swallowing action independently according to the guided video, without the need for additional electrical pulse stimulation. The interval and rest time can be set by the physician or not, and are set by default.

[0085] After the treatment mode is determined, the display 300 displays the treatment interface. The system has three typical swallowing tasks: drink swallowing, shared swallowing, and food swallowing. Figures 12 to 14 The following figure shows a treatment page with a guide animation. To help patients further understand their swallowing disorders and receive more direct visual stimulation, the guide animation can be replaced with the patient's own swallowing angiography animation or other animations, such as Figure 15 Changing the animation can be done in the Customize section of the Treatment Plan page.

[0086] On the treatment page, the left column contains the [Back / Set / Pause] button, treatment countdown, number of successful swallowing groups, treatment mode display and parameter setting area, and the right column contains the electrical stimulation icon area, the real patient swallowing image area captured by the camera, and the guidance animation area. The [Pause] button on the game task interface can pause the device operation (pause the timer, music and electric pulse output), and the [Back] button can return to the treatment main page, such as Figure 15 As shown in (a). The [Settings] button can be used to turn on or off the background music and the successful swallowing prompt sound. When the set rest interval is reached, a pop-up window will pop up on the interface, as shown in the figure Figure 15 As shown in (b), it displays "Rest" and the countdown of the rest time. If you do not need to rest, you can click Cancel Rest or click X in the upper right corner.

[0087] There is a treatment time countdown below the [Back / Set / Pause] button to indicate the remaining treatment time.

[0088] [Number of successful sets] is used to display the number of successful swallowings. In passive mode and active mode, the number of successful swallowings is confirmed by the patient through the handle; in assisted mode, the number of successful swallowings is confirmed by the physician through the handle.

[0089] [Treatment mode display and parameter setting area] Physicians can select and set treatment mode, muscle strength level, and background music.

[0090] [Electrical stimulation icon area]: A pulse waveform icon is designed on the upper left side of the treatment interface. When the electric pulse is output, the waveform chart will light up and flash, and the purple dot on it will move continuously from left to right along the waveform. When the electric pulse is stopped, the waveform chart will not light up and flash, and the purple dot will not move. (The icon effect in the figure is for reference only)

[0091] [Real patient swallowing image area captured by camera], the therapeutic device has its own camera, which is fixed to the therapeutic device through a universally adjustable support frame, so that the patient's own swallowing image can be captured. The doctor can click [Start Recording] or [End Recording] on the interface as needed. The video duration is a fixed duration that can be set. The recorded video is stored in the specified folder on the computer, such as Figure 16 As shown in (a), it is named with video + patient name + date, such as H:\Swallowing therapy\Video\Video_Zhang San_20240808.

[0092] [Guided Animation Area], the default animation is drink swallowing, which can be changed to shared swallowing, food swallowing or angiography. The doctor can click on the animation to select and change the animation. If it is necessary to change to angiography animation, the doctor needs to put the angiography video in *.mp4 (for Android phone videos) or *.mov (for iPhone videos) format into the folder specified by the host before changing the animation. Figure 16 The video name is displayed below the video on the treatment interface to verify whether the correct video has been selected.

[0093] To improve the professionalism of the treatment, the doctor can also participate in the patient's treatment. During the treatment process, the doctor will intervene and control the patient's swallowing performance (such as whether it has started or completed) in real time through the multi-function handle. The specific functions of the handle are as follows:

[0094] (1) Electric pulse output start and stop function: The physician can press and hold the red button on the top of the handle to start the output of electric pulses according to the patient's swallowing performance, and release the button to stop the output;

[0095] (2) Electric pulse intensity adjustment function: The physician can adjust the intensity output by using the scroll wheel or button according to the patient's swallowing performance. The amplitude of each increase or decrease can be set;

[0096] (3) Video recording start and stop button: The doctor can record the patient's swallowing process as needed. Click on the set case to start the video recording. The video recording time can be set. The video recording will automatically stop after the fixed time.

Settings

[0101] The status of the electronic component 100, such as the power level, whether it is communicating and connecting with the host normally, and whether it has fallen off, needs to be displayed on the host. Its status is specifically divided into: normal power level, low power level, not connected, and falling off. The corresponding length is displayed according to the actual power level. When the power level is higher than 10%, it is displayed as a green icon; when the power level is lower than 10%, it is displayed as a red icon. If the electrical stimulation module is not connected to the host, it will be displayed as a gray icon. If any of the electrical stimulation modules falls off from the skin surface, it will be displayed as a yellow icon. The fault information icon is displayed on the page. If Figures 26 to 28 shown.

[0102] In an exemplary embodiment, Figure 29 As shown, the control terminal 500 includes a slave 501, a remote control handle 502 and a host 503. The slave 501 is connected to the electrical stimulation module 101 and the electromyography acquisition module 102 via a lead wire; the host 503 is arranged on the telescopic bracket 200 and is located below the display 300; the remote control handle 502 is signal-connected to the slave 501, and the host 503 communicates with the slave 501 via a wireless connection; the host 503 is connected to the display 300, and the slave 501 is connected to the camera assembly 400.

[0103] In this embodiment, the host 503 serves as the upper computer, and the slave 501 should have the ability to receive commands from the upper computer in real time via WiFi. According to the commands of the upper computer, it controls the collection and transmission of EMG signals, and outputs electrical stimulation signals with specified parameters. After the upper computer enters the corresponding mode or interface, the remote control handle 502 can directly control the working status of the slave 501 and transmit the working status back to the upper computer (such as adjusting the intensity, starting / ending electrical stimulation), or the slave 501 can complete the corresponding calculations or judgments on its own, control the output of electrical stimulation (mainly automatic power assistance mode), or transmit the button signals of the handle to the upper computer (such as starting video recording, swallowing mark button), etc.

[0104] Electronic assembly 100 has two channels, each sharing a single lead wire for EMG acquisition and electrical stimulation output, connected via a 3.5mm audio jack. The slave device is powered by a lithium battery and charged via a Type-C interface with fast charging support. The slave device features an LED to indicate battery level and operating status. When fully charged, the LED remains lit. While charging, a breathing light appears. When the slave device is outputting electrical pulses or acquiring EMG, the LED flashes rapidly (10 Hz). When the battery is low (less than 20%), the LED flashes slowly (2 Hz). The slave device also features a soft on / off key (multi-function key) that can be pressed for 3 seconds to turn the device on and off. The on / off key is located in the center of the front of the PCB, and the Type-C interface is located in the center of the lower edge of the short side of the PCB. When not in use, the slave device 501 can be placed on a charging cradle for storage and charging. Power is drawn from a computer USB port, or it can be charged from a separate power supply.

[0105] The technical parameters of the electronic module formed by the slave 501 and the electronic assembly 100 are as follows:

[0106] Electrical stimulation parameters: Number of electrical stimulation output channels: 2 channels; Single-channel output current capacity: 0-60mA, 255 steps; Pulse output frequency: 1-10Khz; Electric pulse polarity: positive and negative bipolar; Pulse waveform: square wave, sine wave, triangle wave; Pulse width time: 10-1000us.

[0107] EMG parameters: Number of EMG signal acquisition channels: 2; Maximum EMG acquisition frequency: ≥1000 Hz; EMG acquisition input noise: <2.5 μVrms; EMG signal gain range: 1-120; High-pass (20 Hz) and low-pass (500 Hz) filters, and a 50 Hz notch filter. EMG signal output values: Raw value, power value, integrated EMG value, and power spectrum.

[0108] Battery: The slave device is powered by a rechargeable lithium battery. The battery capacity should be sufficient for the slave device to operate normally for more than 5 hours continuously.

[0109] The slave 501 communicates with the host 503 using WIFI communication. In addition, the slave 501 also needs to communicate with the wireless remote control handle 502 (Bluetooth communication), obtain the status of each button of the remote control handle 502, change its own operating status in time, and transmit the case status of the remote control handle 502 to the host 503, so that the host 503 can implement the corresponding functions.

[0110] The control logic of slave 501 is as follows:

[0111] 1) The slave is directly connected to the control handle. The operations of the control handle are received by the slave and forwarded to the host computer, receiving the host computer's instructions;

[0112] 2) After the host computer sets the parameters, it sends the parameter setting command before entering each evaluation or game interface. After receiving the command, the slave verifies that it is successful and sends a successful reception reply data to the host computer. If the verification is unsuccessful or the parameters are not set successfully, it sends a failed reception reply data to request the host computer to resend.

[0113] 3) In passive mode, the slave always outputs electric pulses according to the set parameters, and the electromyographic signal does not need to be measured; in the automatic mode of the power-assisted mode, the slave needs to determine whether to output electric pulse stimulation for a specified time (power-assisted time) based on the measured electromyographic value and the normal electromyographic value; in the manual mode of the power-assisted mode, the output of electric pulses is determined by the pulse control button of the remote control handle; in active mode, the slave does not actively output electric stimulation and only collects EMG signals;

[0114] 4) When the host computer interface does not enter the corresponding evaluation or treatment interface, the slave device does not respond to any button functions of the remote control handle;

[0115] 5) When the host computer reaches the rest time or the rest ends in the evaluation or treatment interface, or the pause or end button is clicked on the interface, the host computer sends a command to control the slave computer to start or stop;

[0116] 6) When the host computer has not entered the evaluation interface and treatment interface, the slave computer sends a heartbeat packet to the host computer at a fixed time (0.5Hz) to let the host computer know that the slave computer is successfully connected; after the host computer enters the evaluation interface and treatment interface, the slave computer sends data format 2 (50Hz) to the host computer at a fixed time and also sends a heartbeat packet (0.5Hz) at a fixed time.
