[0051] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] Embodiment 1:

[0053] The embodiment of the present invention provides a swallowing dysfunction risk management system, such as Figure 1 As shown, including:

[0054] A swallowing training magnetoelectric stimulator 101 is used to generate magnetoelectric stimulation signals;

[0055] An electroencephalogram signal collector 102 is used to collect electroencephalogram signals generated by the patient's brain in response to the magnetic and electric stimulation signals;

[0056] The main control box 103 is connected to the swallowing training magnetic electric stimulator and the EEG signal collector. The main control box includes:

[0057] The processing module 1031 is used to generate a stimulation effect diagram based on the EEG signal, determine a swallowing dysfunction risk assessment result based on the stimulation effect diagram, and generate a magnetic and electric stimulation plan based on the swallowing dysfunction risk assessment result;

[0058] A control module 1032, for controlling parameters of the magnetoelectric stimulation signal based on the magnetoelectric stimulation scheme;

[0059] The risk warning module 1033 is used to formulate corresponding intervention measures and plans based on the swallowing dysfunction risk assessment results.

[0060] like Figure 2 As shown, it is a swallowing training magnetic electric stimulator, which can provide magnetic electric stimulation signals, including:

[0061] A plurality of stimulation electrode sheets 1011, which are used to be attached to preset positions of the patient and provide magnetic and electrical stimulation to the preset positions, and the preset positions are specifically any one or more of the following;

[0062] Superior and inferior hyoid muscles, thyroid cartilage, submental area, and buccal branch of facial nerve;

[0063] The magnetoelectric stimulation pulse generating device 1012 is connected to the plurality of stimulation electrode sheets 1011 and the main control box 103 , and is used to generate a magnetoelectric stimulation pulse signal based on the control instruction output by the main control box 103 .

[0064] Among them, Figure 3As shown, it is the midline of the suprahyoid muscle position. The stimulating electrode can be applied to the suprahyoid muscle position 301 or the infrahyoid muscle position 302 to stimulate the suprahyoid muscle or the infrahyoid muscle. If the two stimulating electrodes are located above the midline position 303 and 304, the muscle system around the epiglottis and the base of the tongue can be stimulated.

[0065] The thyroid cartilage is located below the hyoid bone. By placing a stimulation electrode under the chin, the extrinsic tongue muscles and some intrinsic tongue muscles, as well as the suprahyoid muscles, can be stimulated. By stimulating the facial nerve, the facial muscles contract.

[0066] like Figure 4 As shown, the electroencephalogram signal acquisition device 102 includes:

[0067] A plurality of electrode sheets 401 are applied to the patient's brain to collect brain electrical signals;

[0068] A signal sensor 402, used to sense brain electrical signals;

[0069] The signal amplifier 403 is connected to the main control box 103 and the signal sensor 402 , and is used to amplify the EEG signal to obtain the amplified EEG signal and transmit it to the main control box 103 .

[0070] Specifically, multiple electrode sheets 401 can be arranged inside the hat, and by fixing multiple electrode sheets 401 inside the hat, when the patient wears the hat, the corresponding collection point can be quickly located, thereby improving the efficiency of signal collection. Since the EEG signal can reflect the stimulation effect of the stimulation site.

[0071] The electrode sheets 401 are all in pairs. The signal amplifier 403 is used to amplify the EEG signal for later observation and identification. Of course, in addition to amplifying the EEG signal, it also includes filtering out interference noise, analog-to-digital conversion and other processing processes, and finally transmits it to the main control box 103.

[0072] The processing module 1031 in the main controller 103 can generate a stimulation effect diagram based on the EEG signal.

[0073] Specifically, based on the EEG signal, the brain area corresponding to the stimulation site and the corresponding sensitivity are determined; based on the brain area and sensitivity, a stimulation effect map is generated.

[0074] Since EEG signals have frequency characteristics, amplitude characteristics, and rhythm characteristics, and the response of the corresponding brain area is different when different parts are stimulated. According to the corresponding relationship table between different parts of stimulation and the position of the brain area, the position of the brain area with stimulation effect corresponding to the stimulation part is determined. According to the amplitude and frequency of the EEG signal, the sensitivity of the corresponding part is determined. Since the perception of magnetic and electric stimulation is transmitted to the brain through the nervous system, these perceptions increase and decrease with the change of stimulation. Therefore, when analyzing EEG signals, statistical analysis can be performed to determine the effect of stimulation by taking the mean square error value. Finally, based on the sensitivity of the brain area and the corresponding part, a stimulation effect diagram is generated. For the sensitivity with weaker sensitivity, dark colors are used, and for the sensitivity with stronger sensitivity, light colors are used.

[0075] Through the display of the stimulation effect diagram, the sensitivity corresponding to the stimulation site can be determined. If the sensitivity is strong, it is determined that the excitability and coordination of the corresponding site are better. If the sensitivity is weak, it is determined that the excitability and coordination of the corresponding site are poor and need to be improved.

[0076] Next, the processing module 1031 determines the area of ​​the target brain region corresponding to the part to be improved based on the stimulation effect diagram, where the part to be improved is an area where the sensitivity of the stimulation part is less than the preset sensitivity; and determines the swallowing dysfunction risk assessment result based on the area of ​​the target brain region.

[0077] When determining the area of ​​the target brain region corresponding to the part to be improved, the color of the target brain region corresponding to the part to be improved that is smaller than the preset sensitivity area can be determined, which can be determined specifically according to the gray value of the pixel. Then, by identifying the number of pixels in the target brain region, the area of ​​the target brain region can be determined.

[0078] The larger the target brain area, the more exercise stimulation is needed for the area to be improved, and the smaller the target brain area, the less exercise stimulation is needed for the area to be improved. Of course, this is calculated for the same stimulation area, and for different stimulation areas, it needs to be calculated based on the actual proportion. It will not be described in detail here.

[0079] Finally, the swallowing dysfunction risk assessment result is determined based on the area of ​​the target brain region. Theoretically, the larger the target brain region, the higher the swallowing dysfunction risk assessment result. The smaller the target brain region, the lower the swallowing dysfunction risk assessment result.

[0080] The swallowing dysfunction risk assessment results can be divided into functional feeding levels (FOIS), including:

[0081] Level 1 risk: Complete inability to eat by mouth;

[0082] Level 2 risk: Relying on feeding tubes but able to occasionally take small amounts of food or liquids by mouth;

[0083] Level 3 risk: Need to rely on feeding tube, but can continue to practice eating some food or liquids by mouth;

[0084] Level 4 risk: Eating only single-textured food by mouth;

[0085] Level 5 risk: Foods of various textures are consumed entirely by mouth, but require special preparation and handling;

[0086] Level 6 risk: Eats a variety of foods by mouth without special preparation or handling, but needs to avoid certain foods and liquids;

[0087] Level 7 risk: eating entirely by mouth, without any restrictions;

[0088] After obtaining the swallowing dysfunction risk assessment results, the processing module 1031 is also used to formulate a swallowing function stimulation plan based on the swallowing dysfunction risk assessment results; based on the swallowing function stimulation plan, determine the partition stimulation sequence, corresponding stimulation intensity and stimulation frequency of the magnetic and electric stimulation signal when the swallowing training magnetic and electric stimulator is started each time.

[0089] According to different swallowing dysfunction risk assessment results, a swallowing function stimulation schedule is formulated, which includes the frequency of daily stimulation, the time of stimulation, the number of days, and other information. For each time the swallowing training stimulator is turned on, the stimulation sequence of the stimulation zone needs to be determined. For example, stimulate the less sensitive part first, then stimulate the more sensitive part, so as to achieve the associated stimulation between the parts. The stimulation intensity and frequency are also determined according to the individual conditions of the patients, and will not be elaborated here.

[0090] After the magnetoelectric stimulation scheme is generated, the control module 1032 controls the parameters of the magnetoelectric stimulation signal based on the magnetoelectric stimulation scheme, and the parameters are specifically used to change the stimulation frequency, stimulation intensity and stimulation area, so as to achieve stimulation training under the risk level.

[0091] The main control box 103 further includes: a risk warning module 1033 and a connection processing module 1031, which are specifically used for:

[0092] Determine the degree of risk based on the swallowing dysfunction risk assessment results and the risk assessment standard table; formulate corresponding nutrition management plans, compensatory methods, and rehabilitation management plans based on the degree of risk, and display phased guidance videos for different caregivers through video. The caregivers are specifically professional medical staff, family members, or the patients themselves.

[0093] For example, the risk level of 1 to 3 is determined as high risk, the risk level of 4 to 6 is determined as medium risk, and the risk level of 7 is determined as low risk. Therefore, for any risk level, a corresponding nutrition management plan is formulated, and the nutrition management plan includes: nutrition assessment, nutrition method and nutrition amount. Compensatory methods include: adjustment of food, adjustment of eating posture and adjustment of eating tools, as well as adjustment of bite size and modification of the environment. The rehabilitation management plan includes: attention to oral hygiene, eating management, posture management, secretion management and health guidance.

[0094] There are corresponding plans for different risk levels, and corresponding guidance suggestions are also provided, specifically, staged guidance for different nursing staff is presented in the form of videos. Patients and their families can watch the guidance to provide corresponding care, improve nursing awareness, and avoid patient harm caused by improper care.

[0095] In an optional embodiment, the system further includes: a display for displaying stimulation effect diagrams and phased guidance videos.

[0096] The main control box 103 also includes: an input module, a connection processing module 1031, which is used to:

[0097] After the control module 1032 controls the parameters of the magnetoelectric stimulation signal to act on the patient, the patient's physiological response information is received. The physiological response information is information entered by the nursing staff based on the patient's swallowing condition. The nursing staff specifically determines the patient's swallowing condition with the help of a bedside swallowing function evaluation tool or a Kubota drinking water experiment. The processing module 1031 is also used to: adjust the magnetoelectric stimulation plan based on the physiological response information.

[0098] By comparing the magnetoelectric stimulation program formulated based on the stimulation effect diagram with the manually formulated magnetoelectric stimulation program, the magnetoelectric stimulation program formulated based on the stimulation effect diagram can be adjusted to make up for the difference, improve the accuracy of training, and better enable patients to recover as soon as possible.

[0099] Finally, the main control box 103 also includes: a psychological counseling voice module, a connection processing module 1031, which is used to provide psychological counseling encouragement words to build confidence for patients. Among them, the psychological counseling encouragement words use different psychological counseling encouragement words for different risk levels to adapt to the corresponding scenarios.
