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 one of the common and important complications of stroke, with an incidence rate of up to 50% to 70%. It often manifests as difficulty in swallowing and choking when eating, which can cause aspiration, aspiration pneumonia, malnutrition, and even suffocation.

[0003] To date, the treatment methods for dysphagia after stroke are still limited. Traditional treatment methods mainly include: replacement feeding methods, dietary adjustments, behavioral and posture techniques, peripheral sensory motor stimulation techniques, or active exercises aimed at strengthening the function of selected muscle groups and improving the movement time at the beginning of swallowing. These methods are aimed at ensuring the safety and adequate food intake of patients with dysphagia after stroke. Although these methods have played a certain role in the treatment of dysphagia after stroke, it is still difficult to improve dysphagia after stroke quickly and effectively based on the current results. Therefore, the rehabilitation of dysphagia after stroke is also a major challenge that needs to be solved in the current rehabilitation field.

[0004] In the prior art, CN113729737A discloses a swallowing treatment method based on mirror neurons and its system, including: treatment video production link: the treatment video production link includes recording swallowing videos, and the swallowing videos include three swallowing actions: normal swallowing actions, X-ray fluoroscopy swallowing actions, and swallowing actions under anatomical conditions; treatment plan preparation link: obtaining patient information and selecting swallowing actions at different stages as a treatment plan based on the patient's information; treatment link: identifying the patient's information card, calling up the treatment video, the patient uses VR equipment, watches the treatment video in turn and imitates and learns, and at the same time collects the surface electromyographic signals of the patient's swallowing muscles and enters them into the information card, and compares them with the surface electromyographic signals of the swallowing muscles of normal controls, and simultaneously displays the comparison results to the patient.

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 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 may be configured in the control terminal 500, and the user module 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, the patient performs [User Registration] under the guidance of a physician or by a physician on behalf of the patient, and the information includes name, gender, age, height, weight, swallowing disorder diagnosis, hospitalization number, bed number, admission time, rehabilitation physician, etc., among which name, gender, and age are required information and are used for naming the treatment report. Figure 4 As shown in the figure, when a patient uses the swallowing disorder treatment and 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] In order to effectively evaluate the swallowing ability of patients before treatment, an evaluation interface and animation are designed to guide patients to swallow within a set number of times. The electromyographic acquisition module will synchronously detect the electromyographic signals of patients during swallowing and transmit the signals wirelessly to the control terminal. The control terminal will extract the features after amplification, filtering and denoising of the signals, obtain the quantitative value of the patient's muscle activation, and evaluate the patient's swallowing ability based on the muscle activation degree.

[0071] The evaluation signal obtained by the control terminal includes the selection of the muscle group to be evaluated. The physician can select the muscle group to be evaluated, or can enter the name of the muscle group. The entered 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 remaining 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 guidance animation on the right is drink swallowing, and the physician can also select food swallowing animation. There are swallowing animations and custom animations (contrast video 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 display the strength level of the two muscles (groups) evaluated this time and last time. If no evaluation was performed last time, the value will be displayed as 0. A message "Please keep working hard!" will be attached 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. This will complete the pre-treatment evaluation. You can also select [Re-evaluate].

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

[0074] (1) Passive mode

[0075] It is suitable for patients with dysphagia with muscle strength level 0-4. It outputs electrical stimulation to the patient's treatment area to enhance muscle strength. Program-based treatment is more targeted and achieves standardized rehabilitation, which is safer for patients and more convenient for doctors. The waveform parameters of electrical stimulation in passive mode can be adjusted.

[0076] (2) Assist mode

[0077] It is suitable for patients with swallowing difficulties of level 5-9, helping them to complete the entire swallowing action independently, monitoring the patient's electromyographic value in real time and outputting electrical stimulation to the treatment site simultaneously, achieving a perfect combination of active training and electrical stimulation, strengthening the exercise effect and enhancing the confidence of rehabilitation. The waveform parameters of electrical stimulation in the power-assist 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 assistance, but only relies on the visual and auditory stimulation and feedback on the interactive interface to guide patients to actively complete the swallowing action.

[0080] Based on this, the muscle strength level is divided into 0 to 10 levels according to the swallowing muscle strength of patients and normal people. The system will compare the EMG value evaluated 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 is evaluated to have only 40mv, then the muscle strength level is considered to be level 4. Considering the stability of the swallowing action, the electromyographic 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. Level 10 and higher muscle strength are all displayed as level 10 on the interface.

[0081] In the power-assistance mode, the patient cannot complete the swallowing action by his own strength. Therefore, the power-assistance level is set. When the patient has a certain muscle strength, the device will give the patient the additional muscle strength required to complete the swallowing action. For example, if the power-assistance level is level 3, it means that the patient has level 7 muscle strength (with 70% of the ability corresponding to the electromyographic value of a normal person). When it is detected that the patient has the corresponding ability, the power-assistance mode will take effect and output the corresponding electric pulse stimulation to the patient. The electric pulse intensity is equivalent to 30% of the ability corresponding to the electromyographic value of a normal person. Similarly, the power-assistance level is automatically recommended after the swallowing ability is evaluated. The power-assistance level is set to 1-10, of which 1-5 corresponds to muscle strength levels 5-9; taking into account the individual differences of patients, even if they have 100% of the electromyographic value of a normal person, the patient may not be able to complete the swallowing action, so the subsequent 6-10 levels are used to adjust the power-assistance according to the actual treatment needs. If the power-assistance level is level 3, the intensity of the electric stimulation can be selected as 21-30mA. If it exceeds 30mA, it will automatically jump to level 4.

[0082] like Fig. 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 is always output. 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 starts to rest at the 10th minute after the start of treatment, and the rest time is 3 minutes. There will be a pop-up box 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, there will be no pop-up box to prompt the patient to rest.

[0083] like Fig.10 As shown, in the power-assisted mode, after the swallowing ability is assessed and the muscle strength level is automatically recommended, or the power-assisted level is automatically recommended or set by the physician, you can select the [Automatic] mode for power-assisted mode treatment, that is, when the device automatically detects that the patient's muscle strength exceeds the assessed muscle strength level, it will automatically and continuously output electrical stimulation assistance within the power-assisted time; you can also select the [Manual] mode, and the physician can start and stop the output of electrical pulse stimulation by remote control handle signals according to the patient's swallowing status and swallowing action performance, regardless of whether the patient's muscle strength reaches the muscle strength level, and can increase or decrease the power-assisted level (i.e., the amplitude of electrical pulse stimulation) through the handle. In the [Automatic] mode, the interval time and rest time can be set by the physician, while in the [Manual] mode, the interval time and rest time cannot be set.

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

[0085] After the treatment mode is determined, the display 300 displays the treatment interface. The system has interface visual and auditory guidance under three typical swallowing tasks: drink swallowing, shared swallowing, and food swallowing. Figure 12 to Figure 14 The treatment page with the guide animation is shown. To help patients further understand their personal swallowing disorder and receive more direct visual stimulation, the guide animation can be replaced with the patient's personal swallowing angiography animation or other animations, such as Fig.15 Changing the animation can be done in the Customize section of the treatment plan page.

[0086] In the treatment page, the left column contains the [Return / 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 taken by the camera, and the guide animation area. The [Pause] button on the game task interface can pause the device (pause the timing, music and electrical pulse output), and the [Return] button can return to the main treatment page, such as Fig.15 As shown in (a) in the figure. The [Settings] button can be used to turn on or off the background music and the successful swallowing reminder sound. When the set rest interval is reached, a pop-up window will pop up on the interface, as shown in the figure Fig.15 As shown in (b), it shows "Resting" 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] The doctor can complete the selection and setting of treatment mode, muscle strength level, and background music.

[0090] [Electrical stimulation icon area], there is a pulse waveform icon 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 continue to move from left to right along the waveform. When the electric pulse stops outputting, the waveform chart will not light up and flash, and the purple dot will not move. (The icon effect in the picture 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 body 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, and 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 Fig.16 As shown in (a), the video is named with video+patient name+date, such as H:\Swallowing therapy\Video\Video_Zhang San_20240808.

[0092] [Guide Animation Area], the default animation is drink swallowing, which can be changed to joint swallowing, food swallowing or contrast animation. The doctor can click the animation to select and change the animation. If you need to change to contrast animation, before changing the animation, the doctor needs to put the contrast video in the *.mp4 (video shot by Android phone) or *.mov (video shot by Apple phone) format into the folder specified by the host. Fig.16 As shown in (b) and (c), the video is named with angiography + patient name + date, such as H:\Swallowing therapy\Guided video\Angiography_Zhang San_20231016. The video name is displayed below the angiography video in the treatment interface, which can be used to verify whether the correct video is selected.

[0093] In order to improve the professionalism of the treatment, the doctor can also participate in the patient's treatment. During the treatment, the doctor will intervene and control the patient's swallowing performance (such as whether it is started, whether it is completed, etc.) 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 roller 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 physician can record the patient's swallowing process as needed. Click on the case setting to start the video recording. The video recording duration can be set. The video recording will automatically stop after the fixed duration. If the interval between two consecutive button presses is less than the fixed duration, the second button press will prevail.

[0097] (4) Swallowing completion identification button: When the patient is identified to have completed the swallowing action, the patient or physician presses the green button to indicate that the swallowing action is completed, and the number of successful groups on the interface is accumulated; the handle operation signal will be wirelessly transmitted to the radio stimulation module in real time, and then transmitted to the host computer interface for display through the radio stimulation module.

[0098] exist Figure 5 On the personal center page of , you can click [Report Management] to enter the report management module. Fig.18 In addition, report management also supports the export of multiple individual report data, such as Fig.19 and Fig. 20 The doctor can click [View] for a detailed report, which records every treatment the patient has received, including but not limited to personal information, pre-treatment capacity assessment, treatment plan configuration, treatment effects, etc. Figure 21 to Figure 23 As shown, the treatment report may vary slightly depending on the treatment plan. The report can be saved in the corresponding location of the computer.

[0099] Note: When the patient starts treatment, the electromyographic signal data is collected in real time. After the data is transmitted from the lower computer to the upper computer, it is automatically saved in the specified folder, such as Fig.24 As shown. And named with EMG data + patient name + date and time, such as H:\Swallowing therapy\EMG signal database\EMG data_Zhang San_20240808_16_59_32. Doctors can go to the designated folder to check the data table as needed.

[0100] [Settings] can set and adjust the system's software and hardware related parameters, such as Fig.25 shown.

[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, must be displayed on the host. The status is specifically divided into: normal power level, low power level, disconnected, and fallen 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 is displayed as a gray icon. If any of the electrical stimulation modules falls off from the skin surface, it is displayed as a yellow icon. The fault information icon is displayed on the page. If Figure 26 to Figure 28 shown.

[0102] In an exemplary embodiment, Fig.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 electric 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 state of the slave 501 and transmit the working state to the upper computer (such as adjusting the intensity, starting / ending electrical stimulation), or the slave 501 can complete the corresponding calculations or judgments by itself, 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] The electronic component 100 has two channels in total. The EMG acquisition and electrical stimulation output of each channel share a lead wire, which is connected by a 3.5mm audio interface. The slave is powered by a lithium battery, and the charging adopts a TypeC interface, which supports fast charging. The slave is equipped with an LED to display the power and working status. When the power is sufficient, the LED is always on. When charging, the breathing light is displayed. When the slave is outputting electrical pulses or collecting EMG, the LED flashes quickly (10hz). When the power is insufficient (less than 20%), the LED flashes slowly (2hz). The slave is equipped with a soft switch key (multi-function key), which can be pressed for 3s to turn on / off. The switch key is set in the middle of the front of the PCB board, and the Type C interface is set in the middle of the lower edge of the short side of the PCB board. When the slave 501 is not in use, it can be placed on the charging stand for storage and charging. The charging power is drawn from the USB port of the computer, and it can also be charged through an independent 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; Electrical pulse polarity: positive and negative bipolar; Pulse waveform: square wave, sine wave, triangle wave; Pulse width time: 10-1000us.

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

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

[0109] The slave 501 communicates with the host 503 using WIFI communication. In addition, the slave 501 also needs to communicate with the wirelessly operated 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, and the host 503 implements the corresponding function.

[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, and the slave receives the instructions of the host computer;

[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 successfully and sends a successful reception reply data to the host computer. If the verification fails 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 the electric pulse is determined according to the pulse control button of the remote control handle; in active mode, the slave does not actively output electric stimulation, but 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 all button functions of the remote control handle;

[0115] 5) When the host computer reaches the rest time or the rest time 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 the treatment interface, the slave machine periodically (0.5Hz) sends a heartbeat packet to the host computer to let the host computer know that the slave machine is successfully connected; after the host computer enters the evaluation interface and the treatment interface, the slave machine periodically sends data format 2 (50Hz) to the host computer and also periodically sends a heartbeat packet (0.5Hz).
