It promotes tissue repair, relieves pain, reduces inflammation, etc. by using the effects of electric current and ultrasound at the same time. In order to ensure the therapeutic effect of electro-ultrasonic therapy device on human tissue, the electro-ultrasonic parameters of electro-ultrasonic therapy device need to be accurately set.

[0003] The existing method usually applies a coupling agent on the skin surface of the patient's treatment area and then places an ultrasonic patch. Through the ultrasonic data of the ultrasonic patch, the treatment system in the electro-ultrasonic therapeutic device can automatically set various electro-ultrasonic parameters of the electro-ultrasonic therapeutic device, such as frequency and electric power. However, in actual situations, the ultrasonic data of the ultrasonic patch is affected by uncertain factors such as improper operation and the external environment, resulting in errors in the ultrasonic data of the ultrasonic patch, which in turn makes the electro-ultrasonic parameter setting of the electro-ultrasonic therapeutic device inaccurate, affecting the treatment effect of the electro-ultrasonic therapeutic device, and further affecting the patient's experience.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of an electro-ultrasonic parameter control method and device according to the present invention, its specific implementation, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] The specific scheme of an electro-ultrasonic parameter control method and device provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] Embodiment 1:

[0021] The present invention proposes an electro-ultrasonic parameter control method, please refer to Figure 1 , which shows a schematic flow chart of an electro-ultrasonic parameter control method provided by an embodiment of the present invention, the method comprising the following steps: Step S1: Obtain the ultrasonic data, temperature data and electric power data of each ultrasonic patch at each moment in the current time period.

[0022] Specifically, this embodiment takes a patient as an example for analysis. First, the coupling agent is evenly applied to the surface of the skin corresponding to the part of the patient that needs to be treated, and an ultrasonic patch of appropriate model and size is selected. The ultrasonic patch is placed on the skin surface coated with the coupling agent, and the ultrasonic patch is ensured to be placed stably. Among them, each ultrasonic patch is connected to an electrode through a wire, and these electrodes are responsible for providing electrical energy to the ultrasonic patch. The electrode is connected to the output end of the electric ultrasonic therapeutic device so as to perform electrical stimulation during the treatment process. The electrical stimulation transmits current through the electrode to act on the nerves or muscles, causing muscle contraction or nerve reflex, and further enhancing the treatment effect. The strength of the electrical stimulation is controlled by the size of the electric power. After setting the position of the ultrasonic patch, adjust the ultrasonic intensity, frequency, working mode and other parameters of the electric ultrasonic therapeutic device to treat the part of the patient that needs to be treated.

[0023] In order to improve the treatment effect and ensure the patient's experience during the treatment of the patient by the electro-ultrasonic therapeutic apparatus, it is necessary to adjust the electro-ultrasonic parameters of the electro-ultrasonic therapeutic apparatus in real time. It is known that the electro-ultrasonic parameters are automatically adjusted by the treatment system in the electro-ultrasonic therapeutic apparatus, and the treatment system adjusts each electro-ultrasonic parameter in real time according to the ultrasonic data fed back by each ultrasonic patch. In order to adjust each electro-ultrasonic parameter in real time and accurately, it is necessary to analyze whether each ultrasonic patch is abnormal in real time to ensure that the ultrasonic data of each ultrasonic patch is more accurate. It is known that under normal circumstances, the ultrasonic data of each ultrasonic patch is stable and fluctuates, and the temperature is kept stable, and due to the energy conversion, the difference between the ultrasonic data and the electric power data of the ultrasonic patch at the same time should be large. Therefore, this embodiment obtains the ultrasonic data, temperature data and electric power data of each ultrasonic patch at each moment in the current time period, which is conducive to analyzing the ultrasonic patch with abnormalities at present, and then adjusting the ultrasonic data of the abnormal ultrasonic patch, reducing the interference degree of the ultrasonic data of the abnormal ultrasonic patch due to uncertain factors such as environmental interference or improper operation, and improving the accuracy of automatically obtaining each electro-ultrasonic parameter. In this embodiment, the current time period is set to 10 minutes, and the time interval between two adjacent data collection moments is set to 0.5 seconds. The implementer can set the size of the current time period and the time interval between two adjacent data collection moments according to actual conditions, and there is no limitation here. It should be noted that the end time of the current time period must be the current moment, and at the same time, the electro-ultrasonic therapeutic apparatus has treated the treatment part for at least 11 minutes. Among them, the initial electro-ultrasonic parameters of the electro-ultrasonic therapeutic apparatus are set by the staff based on experience.

[0024] Step S2: According to the fluctuation of the ultrasonic curve and the temperature curve corresponding to each ultrasonic patch at each moment, the coupling abnormality degree of each ultrasonic patch at each moment is obtained.

[0025] In actual situations, the quality of the coupling effect depends on whether the current can be effectively transmitted to the treatment site, and at the same time reflects the efficiency of the ultrasonic energy being transmitted from the ultrasonic probe coupling agent to the skin surface. A good coupling effect means that the electrode can contact the skin evenly and stably, and generate a uniform electric field at the treatment site, and most of the ultrasonic energy is effectively transmitted to the treatment site, and the ultrasonic waveform is stable and uniform; a poor coupling effect means that the energy loss is large, and the current may not be effectively transmitted to the deep tissue under the skin, resulting in a weakened treatment effect. At the same time, when the ultrasonic patch is in poor contact with the skin, there may be bubbles between the ultrasonic patch and the skin, resulting in a decrease in the ultrasonic transmission efficiency, which will make the ultrasonic waveform irregular or distorted. At the same time, due to improper transmission of energy such as current and ultrasonic waves, excessive heat will be generated, causing the temperature of the ultrasonic patch to fluctuate, thereby affecting the characteristics of the coupling medium, the performance of the transducer, and the conduction efficiency of the electrical stimulation. Therefore, this embodiment obtains the degree of coupling abnormality of each ultrasonic patch at each moment according to the fluctuation of the ultrasonic curve and temperature curve corresponding to each ultrasonic patch at each moment. Among them, the greater the degree of coupling abnormality, the more abnormal the corresponding ultrasonic patch is at the corresponding moment. It should be noted that the end time of the corresponding ultrasonic curve and temperature curve at each moment in the current time period is the corresponding moment, and the starting time is the corresponding moment one minute before the current time period. The implementer can set the starting time according to actual conditions and is not limited here.

[0026] Preferably, in one possible implementation of this embodiment, the method for obtaining the degree of coupling anomaly is described in Figure 2 , which shows a flow chart of a method for obtaining the degree of coupling anomaly provided in this embodiment, the method comprising the following steps: Step S201: Obtain the degree of ultrasonic distortion.

[0027] When the fluctuation of the ultrasonic curve corresponding to a certain ultrasonic patch at a certain moment is more unstable, the coupling effect of the ultrasonic patch at that moment is worse. Therefore, this embodiment obtains the ultrasonic distortion degree of each ultrasonic patch at each moment according to the fluctuation of the ultrasonic curve corresponding to each ultrasonic patch at each moment. The greater the ultrasonic distortion degree, the worse the coupling effect of the corresponding ultrasonic patch at the corresponding moment.

[0028] In one way that can be implemented in this embodiment, the method for obtaining the degree of ultrasonic distortion is: for any ultrasonic patch and any moment, obtain the absolute value of the difference between the amplitudes of any two adjacent peaks in the ultrasonic curve corresponding to the ultrasonic patch at that moment, and use them as the first difference; obtain the absolute value of the difference between the corresponding moments of any two adjacent peaks in the ultrasonic curve corresponding to the ultrasonic patch at that moment, and use them as the second difference; when the fluctuations of the first difference and the second difference are greater, the more irregular the ultrasonic wave of the ultrasonic patch at that moment, and then this embodiment uses the product of the variance of the first difference and the variance of the second difference as the degree of ultrasonic distortion of the ultrasonic patch at that moment.

[0029] At this point, the ultrasonic distortion level of each ultrasonic patch at each moment is obtained.

[0030] Step S202: Obtain the degree of temperature abnormality.

[0031] When the fluctuation of the temperature curve corresponding to a certain ultrasonic patch at a certain moment is greater, the temperature of the ultrasonic patch at that moment is more unstable, which indirectly indicates that the coupling effect of the ultrasonic patch at that moment is worse. In this embodiment, the temperature abnormality degree of each ultrasonic patch at each moment is obtained according to the fluctuation of the temperature curve corresponding to each ultrasonic patch at each moment. The greater the temperature abnormality degree, the worse the coupling effect of the corresponding ultrasonic patch at the corresponding moment.

[0032] In one implementable method of the present embodiment, the method for obtaining the degree of temperature abnormality is: for any ultrasonic patch and any moment, obtaining the variance of all temperature data in the temperature curve corresponding to the ultrasonic patch at that moment as the first variance; the larger the first variance, the more unstable the temperature curve corresponding to the ultrasonic patch at that moment, and the more likely that the coupling effect of the ultrasonic patch at that moment is poor; further obtaining the difference between the maximum temperature data and the minimum temperature data in the temperature curve corresponding to the ultrasonic patch at that moment as the third difference; the larger the third difference, the more unstable the temperature curve corresponding to the ultrasonic patch at that moment; in order to accurately analyze the temperature instability of the ultrasonic patch at that moment, the present embodiment uses the product of the first variance and the third difference as the degree of temperature abnormality of the ultrasonic patch at that moment.

[0033] At this point, the temperature abnormality degree of each ultrasound patch at each moment is obtained.

[0034] Step S203: Obtain the degree of coupling abnormality.

[0035] When the ultrasonic distortion degree and the temperature anomaly degree of a certain ultrasonic patch at a certain moment are both greater, it means that the coupling effect of the ultrasonic patch at that moment is worse, and then this embodiment normalizes the product of the ultrasonic distortion degree and the temperature anomaly degree of the ultrasonic patch at that moment as the coupling anomaly degree of the ultrasonic patch at that moment. In this embodiment, the product of the ultrasonic distortion degree and the temperature anomaly degree is normalized by the norm normalization function.

[0036] At this point, the degree of coupling abnormality of each ultrasonic patch at each moment is obtained.

[0037] Step S3: Divide the ultrasound patch into abnormal patches and normal patches based on the degree of coupling abnormality; obtain the abnormal patches and normal patches belonging to the same treatment site according to the difference between the ultrasonic data and the electric power data of each abnormal patch at each moment, and the degree of coupling abnormality between each abnormal patch and each normal patch at each moment.

[0038] It is known that the greater the degree of coupling abnormality, the more abnormal the corresponding ultrasound patch is at the corresponding moment. The more moments when a certain ultrasound patch has a large degree of coupling abnormality in the current time period, the greater the possibility that the ultrasound patch is abnormal. Therefore, this embodiment divides the ultrasound patch into abnormal patches and normal patches based on the degree of coupling abnormality.

[0039] Preferably, in a method that can be implemented in this embodiment, the method of dividing the ultrasonic patch into abnormal patches and normal patches based on the degree of coupling abnormality is: for any ultrasonic patch, obtain the degree of coupling abnormality of the ultrasonic patch at each moment in the current time period, and when the degree of coupling abnormality is greater than or equal to the preset coupling abnormality threshold, the corresponding moment is taken as an abnormal moment; this embodiment sets the preset coupling abnormality threshold to 0.5, and the implementer can set the size of the preset coupling abnormality threshold according to actual conditions, which is not limited here. When the number of abnormal moments is greater than or equal to the preset number threshold, the ultrasonic patch is an abnormal patch; when the number of abnormal moments is less than the preset number threshold, the ultrasonic patch is a normal patch. This embodiment sets the preset number threshold to 4, and the implementer can set the size of the preset number threshold according to actual conditions, which is not limited here. So far, the ultrasonic patch is divided into two categories: abnormal patches and normal patches.

[0040] In actual situations, there may be multiple parts that are treated by the electro-ultrasonic therapeutic device at the same time. It is known that the coupling conditions of the ultrasonic patches under the same treatment part are similar, and the coupling conditions of the ultrasonic patches under different treatment parts are different. It can be inferred that the abnormal coupling conditions of the abnormal patches in the same treatment part are similar, and the coupling conditions of the normal patches in the same treatment part are similar. Considering that the difference in the coupling conditions between the normal patches and the abnormal patches in the same treatment part is definitely obvious, therefore, this embodiment first analyzes the abnormal patches belonging to the same treatment part and the normal patches belonging to the same treatment part, and then analyzes the difference in coupling conditions between the abnormal patches in each treatment part and the normal patches in each treatment part, and finally determines the abnormal patches and normal patches belonging to the same treatment part.

[0041] It should be noted that when the difference between the ultrasonic data and the electric power data of an abnormal patch at a certain moment is smaller, it means that the energy transfer of the ultrasound and the electric energy input of the electrical stimulation are more consistent at this time. The synchronous release and transfer of the energy of the two will lead to excessive local energy concentration, thereby causing the local temperature of the abnormal patch to rise, even beyond the normal range, and thus affecting the coupling effect. Therefore, the abnormal degree of coupling of the abnormal patch at this moment should be greater. In order to comprehensively analyze the coupling of each abnormal patch in the current time period, and then analyze the abnormal patches belonging to the same treatment site, this embodiment obtains the abnormal patches belonging to the same treatment site according to the difference between the ultrasonic data and the electric power data of each abnormal patch at each moment, and the abnormal degree of coupling of each abnormal patch at each moment.

[0042] Therefore, this embodiment obtains abnormal patches and normal patches belonging to the same treatment site based on the difference between the ultrasonic data and the electric power data of each abnormal patch at each moment, and the degree of coupling abnormality between each abnormal patch and each normal patch at each moment.

[0043] Preferably, in a method that can be implemented in this embodiment, the method for obtaining abnormal patches and normal patches belonging to the same treatment site is: for any abnormal patch, the result of normalizing the absolute value of the difference between the ultrasonic data and the electric power data of the abnormal patch at each moment in the current time period is used as the difference evaluation value of the abnormal patch at the corresponding moment; it should be noted that before obtaining the difference evaluation value, this embodiment firstly performs normalization processing on the ultrasonic data and the electric power data of the abnormal patch at each moment in the current time period to ensure that the value range of the ultrasonic data and the electric power data is consistent. Among them, the standardization of data is a well-known technology and will not be described in detail; When the difference evaluation value is less than the preset difference evaluation threshold, the corresponding moments are all taken as the first moment; when the difference evaluation value is greater than or equal to the preset difference evaluation threshold, the corresponding moments are all taken as the second moment; this embodiment sets the preset difference evaluation threshold to 0.5, and the implementer can set the size of the preset difference evaluation threshold according to the actual situation, which is not limited here. Among them, the greater the coupling abnormality of the abnormal patch at the first moment, the smaller the reasonable coupling degree of the abnormal patch should be; the smaller the coupling abnormality of the abnormal patch at the second moment, the greater the reasonable coupling degree of the abnormal patch should be; in order to more accurately and quickly analyze the reasonable coupling situation of the abnormal patch in the current time period, the time periods corresponding to the continuous first moment and the continuous second moment are divided into an independent time period, that is, the current time period is divided into multiple independent time periods, and each independent time period is analyzed to accurately obtain the reasonable coupling situation of the abnormal patch in each independent time period, and then accurately obtain the reasonable coupling situation of the abnormal patch in the current time period. Therefore, according to the magnitude and fluctuation of the coupling abnormality degree of the abnormal patch in each independent time period, as well as the magnitude of the difference evaluation value, the reasonable contribution degree of the abnormal patch in each independent time period is obtained; the greater the reasonable contribution degree, the better the coupling effect of the abnormal patch in the corresponding independent time period; In one possible implementation of the present embodiment, the method for obtaining a reasonable contribution degree is as follows: for any independent time period, obtain the variance of the coupling abnormality degree of the abnormal patch in the independent time period as a reference variance; obtain the mean of all coupling abnormality degrees of the abnormal patch in the independent time period as a reference coupling abnormality value; when the reference variance and the reference coupling abnormality value are both smaller, it means that the coupling effect of the abnormal patch in the independent time period is better; in order to more accurately analyze the coupling effect, further obtain the mean of all difference evaluation values ​​of the abnormal patch in the independent time period as a reference difference value; the larger the reference difference value, the better the coupling effect of the abnormal patch in the independent time period. In order to accurately analyze the coupling effect of the abnormal patch in the independent time period, the reasonable contribution degree of the abnormal patch in the independent time period is obtained according to the reference variance, the reference coupling abnormality value and the reference difference value; wherein the reference variance and the reference coupling abnormality value are both negatively correlated with the reasonable contribution degree, and the reference difference value is positively correlated with the reasonable contribution degree; The calculation formula for reasonable contribution degree is: ; In the formula, is the reasonable contribution degree of the a-th abnormal patch in the v-th independent time period; is the reference variance; is the first preset constant, greater than 0; is the reference coupling outlier; is the reference difference value; norm is the normalization function. 0.1, implementers can set it according to actual conditions The size of is not limited here; The mean of all reasonable contribution degrees is taken as the first eigenvalue of the abnormal patch; the larger the first eigenvalue, the better the coupling effect of the abnormal patch in the current time period. Among them, the more equal the first eigenvalues ​​of the abnormal patches are, the more likely they are abnormal patches in the same treatment site. Then, this embodiment obtains the first eigenvalue of each abnormal patch, and divides the abnormal patches into abnormal patch categories according to the size of the first eigenvalue through the DBSCAN density clustering algorithm; wherein, an abnormal patch category represents the abnormal patches contained in a treatment site. Among them, the DBSCAN density clustering algorithm is a well-known technology and will not be described in detail. It should be noted that this embodiment sets the neighborhood distance threshold in the DBSCAN density clustering algorithm to 0.3 and the minimum number of neighborhood samples to 3. The implementer can set the neighborhood distance threshold and the minimum number of neighborhood samples according to the actual situation, which are not limited here; so far, the abnormal patches in each treatment site are obtained; For any normal patch, the average value of all coupling abnormalities of the normal patch in the current time period is used as the second eigenvalue of the normal patch; the second eigenvalues ​​of all normal patches are obtained, and the normal patches are divided into normal patch categories according to the size of the second eigenvalues ​​by using the DBSCAN density clustering algorithm; wherein a normal patch category represents the normal patches contained in a treatment site; so far, the normal patches in each treatment site are obtained; It is known that there is an obvious difference in the degree of coupling abnormality between the normal patch and the abnormal patch belonging to the same treatment site. Therefore, according to the difference in the degree of coupling abnormality between each abnormal patch category and each normal patch category, the abnormal patch and the normal patch belonging to the same treatment site are obtained in this embodiment. The specific operation is as follows: For any abnormal patch category, obtain the average of all coupling abnormality levels of all abnormal patches in the abnormal patch category in the current time period as the first coupling abnormality value of the abnormal patch category; obtain the average of all coupling abnormality levels of all normal patches in each normal patch category in the current time period as the second coupling abnormality value of each normal patch category; obtain the difference between the first coupling abnormality value and each second coupling abnormality value, all as the first reference value; take the normal patch in the normal patch category corresponding to the largest first reference value and the abnormal patch in the abnormal patch category as the abnormal patch and normal patch of the same treatment site. It should be noted that when a normal patch category is matched with an abnormal patch category, it will no longer participate in the subsequent division of abnormal patches and normal patches of the same treatment site.

[0044] In actual situations, if there are too many abnormal patches in a certain treatment site, the degree of interference to the ultrasonic patch in the treatment site is too large. At this time, the ultrasonic data of the ultrasonic patch in the treatment site is of little significance for reference, for example, because the operation is very irregular or the ultrasonic patches in the treatment site are all ultrasonic patches with material defects or faults. Therefore, in another embodiment of this embodiment, for any treatment site, when the number of abnormal patches in the treatment site is greater than half of the total number of ultrasonic patches in the treatment site, it means that there are too many abnormal patches in the treatment site. The abnormal patches in the treatment site may be caused by avoidable factors such as very irregular operation or the ultrasonic patches in the treatment site are all ultrasonic patches with material defects or faults. In order to reduce the degree of interference of avoidable factors, all ultrasonic patches in the treatment site are replaced, and the operation rules are improved at the same time. Then, the abnormal patches are analyzed again for the treatment site after the ultrasonic patches are replaced, until the number of abnormal patches in each treatment site is less than half of the total number of ultrasonic patches in the corresponding treatment site.

[0045] Step S4: According to the difference in ultrasonic data between each abnormal patch and each normal patch in each treatment site at each moment, and the degree of coupling abnormality of each abnormal patch at each moment, the ultrasonic data of each abnormal patch at each moment is corrected to obtain the corrected ultrasonic data of each abnormal patch at each moment.

[0046] It is known that when the coupling abnormality degree of an abnormal patch at a certain moment in the current time period is greater, it means that the possibility of abnormality in the ultrasonic data of the abnormal patch at that moment is greater, and the degree to which the ultrasonic data of the abnormal patch at that moment needs to be corrected should be greater; at the same time, the correction trend of the ultrasonic data of the abnormal patch at that moment should be closer to the ultrasonic data of the normal patch in the treatment site where the abnormal patch is located at that moment. Therefore, this embodiment corrects the ultrasonic data of each abnormal patch at each moment according to the difference in ultrasonic data between each abnormal patch and each normal patch in each treatment site at each moment, and the coupling abnormality degree of each abnormal patch at each moment, and obtains the corrected ultrasonic data of each abnormal patch at each moment.

[0047] Preferably, in a manner that can be implemented in the present embodiment, the method for obtaining corrected ultrasonic data is: for any abnormal patch in any treatment site and any moment in the current time period, obtain the mean value of the ultrasonic data of all normal patches in the treatment site at that moment as the reference ultrasonic data; use the difference between the ultrasonic data of the abnormal patch at that moment and the reference ultrasonic data as the correction reference value; use the product of the coupling abnormality degree of the abnormal patch at that moment and the correction reference value as the adjusted ultrasonic data of the abnormal patch at that moment; and use the subtraction result of the ultrasonic data of the abnormal patch at that moment and the adjusted ultrasonic data as the corrected ultrasonic data of the abnormal patch at that moment.

[0048] At this point, the corrected ultrasonic data of each ultrasonic patch at each moment in the current time period is obtained.

[0049] Step S5: Acquire electro-ultrasonic parameters based on the corrected ultrasonic data.

[0050] Specifically, the corrected ultrasonic data of each abnormal patch at each moment in the current time period and the ultrasonic data of each normal patch at each moment in the current time period are input into the treatment system of the electro-ultrasonic therapeutic device. The treatment system will automatically and accurately obtain various electro-ultrasonic parameters to ensure that the ultrasonic energy in the treatment process can be fully and effectively transmitted to the treatment site, thereby improving the treatment effect of the treatment site, enhancing the patient experience, and avoiding the problem of unsatisfactory treatment effect due to poor coupling effect of the ultrasonic patch.

[0051] In summary, the present embodiment obtains ultrasonic data, temperature data and electric power data of an ultrasonic patch; obtains the coupling abnormality degree of the ultrasonic patch according to the ultrasonic data and temperature data, and divides the ultrasonic patch into abnormal patches and normal patches; obtains abnormal patches and normal patches belonging to the same treatment site according to the difference between the ultrasonic data and the electric power data of the abnormal patch, and the coupling abnormality degree; obtains the corrected ultrasonic data of the abnormal patch according to the ultrasonic data difference between the abnormal patch and the normal patch in each treatment site, and the coupling abnormality degree of the abnormal patch, and then obtains the electro-ultrasonic parameters. The present invention improves the accuracy of real-time adjustment of each electro-ultrasonic parameter by accurately obtaining the corrected ultrasonic data of each abnormal patch at each moment in real time, which is conducive to the electro-ultrasonic therapeutic apparatus to effectively treat patients.
