Technical Field

[0001] The present invention relates to the technical field of electro - ultrasonic therapy, and particularly to a method and device for controlling electro - ultrasonic parameters. Background Art

[0002] An electro - ultrasonic therapeutic apparatus is a medical device that combines electrotherapy and ultrasound therapy, and is widely used in fields such as physical therapy, rehabilitation, and pain management. It promotes tissue repair, relieves pain, reduces inflammation, etc. by simultaneously using the effects of electric current and ultrasonic waves. To ensure the therapeutic effect of the electro - ultrasonic therapeutic apparatus on human tissues, it is necessary to accurately set the electro - ultrasonic parameters of the electro - ultrasonic therapeutic apparatus.

[0003] Existing methods usually apply a coupling agent on the skin surface of the patient's treatment area and then place an ultrasonic patch. Through the ultrasonic data of the ultrasonic patch, the treatment system in the electro - ultrasonic therapeutic apparatus can automatically set various electro - ultrasonic parameters of the electro - ultrasonic therapeutic apparatus, such as parameters like 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 external environment, resulting in errors in the ultrasonic data of the ultrasonic patch. Consequently, the electro - ultrasonic parameters of the electro - ultrasonic therapeutic apparatus are inaccurately set, affecting the therapeutic effect of the electro - ultrasonic therapeutic apparatus and further affecting the patient's experience. Summary of the Invention

[0004] In order to solve the technical problem that due to being affected by uncertain factors such as improper operation and external environment, the ultrasonic data of the ultrasonic patch has errors, resulting in inaccurate setting of various electro - ultrasonic parameters of the electro - ultrasonic therapeutic apparatus, the purpose of the present invention is to provide a method and device for controlling electro - ultrasonic parameters, and the specific technical solutions adopted are as follows:

[0005] In a first aspect, an embodiment of the present invention provides a method for controlling electro - ultrasonic parameters, and the method includes the following steps:

[0006] Obtain ultrasonic data, temperature data, and electric power data of each ultrasonic patch at each moment within the current time period;

[0007] According to the fluctuation conditions of the ultrasonic curve and temperature curve corresponding to each ultrasonic patch at each moment, obtain the degree of coupling abnormality of each ultrasonic patch at each moment;

[0008] Divide the ultrasonic patches into abnormal patches and normal patches based on the degree of coupling abnormality; according to the difference between the ultrasonic data and electric power data of each abnormal patch at each moment, and the degree of coupling abnormality of each abnormal patch and each normal patch at each moment, obtain the abnormal patches and normal patches belonging to the same treatment site;

[0009] Based on the ultrasonic data difference between each abnormal patch and each normal patch within each treatment site at each moment, as well as the coupling abnormality degree of each abnormal patch at each moment, correct the ultrasonic data of each abnormal patch at each moment to obtain the corrected ultrasonic data of each abnormal patch at each moment;

[0010] Obtain electro-ultrasonic parameters based on the corrected ultrasonic data.

[0011] Further, the method for obtaining the coupling abnormality degree is as follows:

[0017] Take the product of the first variance and the third difference as the temperature abnormality degree of the ultrasonic patch at that moment;

[0018] Take the normalized result of the product of the ultrasonic distortion degree and the temperature abnormality degree as the coupling abnormality degree of the ultrasonic patch at that moment.

[0019] Further, the method for classifying ultrasonic patches into abnormal patches and normal patches based on the coupling abnormality degree is as follows:

When the coupling abnormality degree is greater than or equal to the preset coupling abnormality degree threshold, take the corresponding moment as an abnormal moment;

[0021] When the number of abnormal moments is greater than or equal to the preset number threshold, the ultrasonic patch is an abnormal patch;

[0022] When the number of abnormal moments is less than the preset number threshold, the ultrasonic patch is a normal patch.

[0023] Further, the method for obtaining abnormal patches and normal patches belonging to the same treatment site is as follows:

[0024] For any abnormal patch, the result of normalizing the difference between the ultrasonic data and the electric power data at each moment within the current time period of this abnormal patch is used as the difference evaluation value at the corresponding moment of this abnormal patch;

[0025] When the difference evaluation value is less than the preset difference evaluation threshold, all corresponding moments are taken as the first moments;

[0026] When the difference evaluation value is greater than or equal to the preset difference evaluation threshold, all corresponding moments are taken as the second moments;

[0027] The time periods corresponding to consecutive first moments and consecutive second moments are each divided into an independent time period. According to the magnitude and fluctuation of the coupling abnormality degree of this abnormal patch within each independent time period, as well as the magnitude of the difference evaluation value, the reasonable contribution degree of this abnormal patch within each independent time period is obtained;

[0028] The average value of all reasonable contribution degrees is used as the first eigenvalue of this abnormal patch;

[0029] According to the first eigenvalue, the abnormal patches are classified into abnormal patch categories through the DBSCAN density clustering algorithm;

[0030] For any normal patch, the average value of all coupling abnormality degrees of this normal patch within the current time period is used as the second eigenvalue of this normal patch;

[0031] According to the second eigenvalue, the normal patches are classified into normal patch categories through the DBSCAN density clustering algorithm;

[0032] According to the difference in the coupling abnormality degree between each abnormal patch category and each normal patch category, the abnormal patches and normal patches belonging to the same treatment site are obtained.

[0033] Further, the method for obtaining the reasonable contribution degree is as follows:

[0034] For any independent time period, the variance of the coupling abnormality degree of this abnormal patch within this independent time period is obtained as the reference variance;

[0035] The average value of all coupling abnormality degrees of this abnormal patch within this independent time period is obtained as the reference coupling abnormality value;

[0036] The average value of all difference evaluation values of this abnormal patch within this independent time period is obtained as the reference difference value;

[0037] According to the reference variance, reference coupling outliers, and reference difference value, obtain the reasonable contribution degree of the abnormal patch during the independent time period; wherein, both the reference variance and the reference coupling outliers are negatively correlated with the reasonable contribution degree, and the reference difference value is positively correlated with the reasonable contribution degree.

[0038] Further, the method for obtaining the abnormal patches and normal patches belonging to the same treatment site according to the difference in the coupling abnormality degree between each abnormal patch category and each normal patch category is as follows:

[0039] For any abnormal patch category, obtain the mean value of all the coupling abnormality degrees of all the abnormal patches in the abnormal patch category during the current time period as the first coupling outlier value of the abnormal patch category;

[0040] Obtain the mean value of all the coupling abnormality degrees of all the normal patches in each normal patch category during the current time period as the second coupling outlier value of each normal patch category;

[0041] Obtain the difference between the first coupling outlier value and each of the second coupling outlier values as the first reference value;

[0042] Take the normal patches in the normal patch category corresponding to the largest first reference value and the abnormal patches in the abnormal patch category as the abnormal patches and normal patches of the same treatment site.

[0043] Further, the electro - ultrasonic parameter control method further includes:

[0044] 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, replace all the ultrasonic patches in the treatment site.

[0045] Further, the method for obtaining the corrected ultrasonic data is as follows:

[0046] For any abnormal patch in any treatment site and any moment during the current time period, obtain the mean value of the ultrasonic data of all the normal patches in the treatment site at that moment as the reference ultrasonic data;

[0047] Take the difference between the ultrasonic data of the abnormal patch at that moment and the reference ultrasonic data as the correction reference value;

[0048] Take 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;

[0049] Take 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.

[0050] Further, the method for obtaining electro-ultrasonic parameters based on the corrected ultrasonic data is as follows:

[0051] Input 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 into the treatment system of the electro-ultrasonic therapeutic instrument, and the treatment system will automatically obtain the electro-ultrasonic parameters.

[0060] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the accompanying drawings and preferred embodiments to detail the specific implementation manners, structures, features and effects of an electro - ultrasonic parameter control method and device proposed according to the present invention. In the following description, different "an embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0062] The following specifically describes the specific solutions of an electro - ultrasonic parameter control method and device provided by the present invention with reference to the accompanying drawings.

[0063] Embodiment 1:

[0064] The present invention proposes an electro - ultrasonic parameter control method. Please refer to Figure 1 , which shows a schematic flowchart of an electro - ultrasonic parameter control method provided by an embodiment of the present invention. The method includes the following steps:

[0065] Step S1: Obtain ultrasonic data, temperature data, and electric power data of each ultrasonic patch at each moment within the current time period.

[0066] Specifically, in this embodiment, a patient is taken as an example for analysis. First, the coupling agent is evenly applied to the surface of the skin corresponding to the treatment site of the patient. An ultrasonic patch of an appropriate model and size is selected and placed on the skin surface coated with the coupling agent, and it is ensured that the ultrasonic patch is placed stably. Each ultrasonic patch is connected to an electrode through a wire, and these electrodes are responsible for supplying electrical energy to the ultrasonic patch. The electrodes are connected to the output end of the electro-ultrasonic therapeutic apparatus so as to perform electrical stimulation during the treatment. The electrical stimulation passes an electric current through the electrodes 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 magnitude of the electrical power. After setting the position of the ultrasonic patch, parameters such as the ultrasonic intensity, frequency, and working mode of the electro-ultrasonic therapeutic apparatus are adjusted to treat the part of the patient that needs treatment.

[0067] During the treatment of the patient by the electro-ultrasonic therapeutic apparatus, in order to improve the treatment effect and ensure the patient experience, 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 accurately in real time, 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 fluctuates stably, the temperature remains stable, and due to the energy conversion, the difference between the ultrasonic data and the electrical power data of the ultrasonic patch should be relatively large at the same moment. Therefore, in this embodiment, obtaining the ultrasonic data, temperature data, and electrical power data of each ultrasonic patch at each moment within the current time period is beneficial 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 uncertain factors such as environmental interference or improper operation on the ultrasonic data of the abnormal ultrasonic patch, 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 acquisition 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 acquisition moments according to the actual situation, which is not limited here. It should be noted that the end moment of the current time period must be the current moment, and at the same time, the electro-ultrasonic therapeutic apparatus has at least treated the treatment site for 11 minutes. The initial electro-ultrasonic parameters of the electro-ultrasonic therapeutic apparatus are set by the staff according to experience.

[0068] Step S2: According to the fluctuation conditions of the ultrasonic curve and the temperature curve corresponding to each ultrasonic patch at each moment, obtain the coupling abnormality degree of each ultrasonic patch at each moment.

[0069] In actual situations, the quality of the coupling effect depends on whether the current can be effectively conducted to the treatment site, and at the same time reflects the efficiency of ultrasonic energy transfer 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, generate a uniform electric field at the treatment site, and most of the ultrasonic energy is effectively transferred to the treatment site, and the waveform of the ultrasonic wave is stable and uniform; a poor coupling effect means that there is a large amount of energy loss, and the current may not be effectively transferred 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 contact, resulting in a reduction in the conduction efficiency of the ultrasonic wave, which will make the ultrasonic waveform irregular or distorted. At the same time, due to improper energy transfer such as current and ultrasonic waves, excessive heat will be generated, resulting in fluctuations in the temperature of the ultrasonic patch, which will in turn affect the characteristics of the coupling medium, the performance of the transducer, and the conduction efficiency of the electrical stimulation. Therefore, in this embodiment, according to the fluctuations of the ultrasonic wave 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. Among them, the greater the coupling abnormality degree, the more abnormal the corresponding ultrasonic patch is at the corresponding moment. It should be noted that the cut-off moment of the ultrasonic wave curve and the temperature curve corresponding to each moment in the current time period is the corresponding moment, and the starting moment is the corresponding moment of the previous minute of the current time period. The implementer can set the starting moment according to the actual situation, which is not limited here.

[0070] Preferably, in a feasible implementation manner of this embodiment, for the method of obtaining the coupling abnormality degree, please refer to Figure 2 which shows a flowchart of a method for obtaining the coupling abnormality degree provided in this embodiment. The method includes the following steps:

[0071] Step S201: Obtain the ultrasonic distortion degree.

[0072] When the fluctuation of the ultrasonic wave 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, in this embodiment, according to the fluctuation of the ultrasonic wave curve corresponding to each ultrasonic patch at each moment, the ultrasonic distortion degree of each ultrasonic patch at each moment is obtained. The greater the ultrasonic distortion degree, the worse the coupling effect of the corresponding ultrasonic patch at the corresponding moment.

[0073] In a feasible implementation manner of this embodiment, the method for obtaining the ultrasonic distortion degree is as follows: for any ultrasonic patch and any moment, the absolute value of the difference between the amplitudes of any two adjacent wave peaks in the ultrasonic wave curve corresponding to the ultrasonic patch at this moment is used as the first difference; the absolute value of the difference between the corresponding moments of any two adjacent wave peaks in the ultrasonic wave curve corresponding to the ultrasonic patch at this moment is used as the second difference; when the fluctuations of both the first difference and the second difference are greater, the ultrasonic wave of the ultrasonic patch at this moment is more irregular. Furthermore, in this embodiment, the product of the variance of the first difference and the variance of the second difference is used as the ultrasonic distortion degree of the ultrasonic patch at this moment.

[0074] Thus, the ultrasonic distortion degree of each ultrasonic patch at each moment is obtained.

[0075] Step S202: Obtain the temperature abnormality degree.

[0076] 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 this moment is more unstable, which indirectly indicates that the coupling effect of the ultrasonic patch at this moment is worse. Furthermore, in this embodiment, according to the fluctuation of the temperature curve corresponding to each ultrasonic patch at each moment, the temperature abnormality degree of each ultrasonic patch at each moment is obtained. The greater the temperature abnormality degree, the worse the coupling effect of the corresponding ultrasonic patch at the corresponding moment.

[0077] In a feasible implementation manner of this embodiment, the method for obtaining the temperature abnormality degree is as follows: for any ultrasonic patch and any moment, the variance of all temperature data in the temperature curve corresponding to the ultrasonic patch at this moment is used as the first variance; the greater the first variance, the more unstable the temperature curve corresponding to the ultrasonic patch at this moment, and the more likely the coupling effect of the ultrasonic patch at this moment is bad; further, the difference between the maximum temperature data and the minimum temperature data in the temperature curve corresponding to the ultrasonic patch at this moment is obtained as the third difference; the greater the third difference, it also indicates that the temperature curve corresponding to the ultrasonic patch at this moment is more unstable; in order to accurately analyze the temperature instability of the ultrasonic patch at this moment, in this embodiment, the product of the first variance and the third difference is used as the temperature abnormality degree of the ultrasonic patch at this moment.

[0078] Thus, the temperature abnormality degree of each ultrasonic patch at each moment is obtained.

[0079] Step S203: Obtain the coupling abnormality degree.

[0080] When the ultrasonic distortion degree and the temperature anomaly degree of a certain ultrasonic patch are both greater at a certain moment, it indicates that the coupling effect of the ultrasonic patch at this moment is worse. Furthermore, in this embodiment, the normalized result of the product of the ultrasonic distortion degree and the temperature anomaly degree of the ultrasonic patch at this moment is used as the coupling anomaly degree of the ultrasonic patch at this moment. Among them, in this embodiment, the product of the ultrasonic distortion degree and the temperature anomaly degree is normalized through the norm normalization function.

[0081] Thus, the coupling anomaly degree of each ultrasonic patch at each moment is obtained.

[0082] Step S3: Divide the ultrasonic patches into abnormal patches and normal patches based on the coupling anomaly degree; according to the difference between the ultrasonic data and the electric power data of each abnormal patch at each moment, and the coupling anomaly degree of each abnormal patch and each normal patch at each moment, obtain the abnormal patches and normal patches belonging to the same treatment site.

[0083] It is known that the greater the coupling anomaly degree, the more abnormal the corresponding ultrasonic patch is at the corresponding moment. When there are more moments with a large coupling anomaly degree for a certain ultrasonic patch during the current time period, it indicates that the possibility of the ultrasonic patch being abnormal is greater. Furthermore, in this embodiment, the ultrasonic patches are divided into abnormal patches and normal patches based on the coupling anomaly degree.

[0084] Preferably, in a realizable manner of this embodiment, the method for dividing the ultrasonic patches into abnormal patches and normal patches based on the coupling anomaly degree is as follows: For any ultrasonic patch, obtain the coupling anomaly degree of the ultrasonic patch at each moment during the current time period. When the coupling anomaly degree is greater than or equal to the preset coupling anomaly degree threshold, the corresponding moment is used as an abnormal moment; in this embodiment, the preset coupling anomaly degree threshold is set to 0.5, and the implementer can set the size of the preset coupling anomaly degree threshold according to the actual situation, 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. In this embodiment, the preset number threshold is set to 4, and the implementer can set the size of the preset number threshold according to the actual situation, which is not limited here. Thus, the ultrasonic patches are divided into two categories: abnormal patches and normal patches.

[0085] In actual situations, there may be multiple treatment sites being treated simultaneously by an electro-ultrasonic therapeutic apparatus. It is known that the coupling conditions of ultrasonic patches under the same treatment site are similar, while there are differences in the coupling conditions of ultrasonic patches under different treatment sites. Thus, it can be inferred that the coupling anomalies of abnormal patches located in the same treatment site are similar, and the coupling conditions of normal patches in the same treatment site are similar. Considering that the differences in the coupling conditions between normal patches and abnormal patches within the same treatment site are surely obvious, therefore, in this embodiment, abnormal patches belonging to the same treatment site and normal patches belonging to the same treatment site are first analyzed, and then the differences in the coupling conditions between the abnormal patches of each treatment site and the normal patches of each treatment site are analyzed, and finally, the abnormal patches and normal patches belonging to the same treatment site are determined.

[0086] It should be noted that when the difference between the ultrasonic data and the electric power data of a certain abnormal patch at a certain moment is smaller, it indicates that the energy transfer of the ultrasonic wave and the electric energy input of the electrical stimulation are more consistent at this time. The synchronous release and transfer of the two energies will cause excessive local energy concentration, thereby causing the local temperature of the abnormal patch to rise, even exceeding the normal range, and further affecting the coupling effect. Therefore, the degree of coupling anomaly of the abnormal patch at this moment should be greater. In order to comprehensively analyze the coupling conditions of each abnormal patch within the current time period and then analyze the abnormal patches belonging to the same treatment site, in this embodiment, the abnormal patches belonging to the same treatment site are obtained 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 anomaly of each abnormal patch at each moment.

[0087] Therefore, in this embodiment, the abnormal patches and normal patches belonging to the same treatment site are obtained 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 anomaly of each abnormal patch and each normal patch at each moment.

[0088] Preferably, in a feasible implementation manner of this embodiment, the method for obtaining the abnormal patches and normal patches belonging to the same treatment site is as follows: for any abnormal patch, the normalized result of the absolute value of the difference between the ultrasonic data and the electric power data of the abnormal patch at each moment within the current time period is used as the difference evaluation value corresponding to the abnormal patch at that moment; it should be noted that before obtaining the difference evaluation value, in this embodiment, the ultrasonic data and the electric power data of the abnormal patch at each moment within the current time period are first standardized to ensure that the value ranges of the ultrasonic data and the electric power data are consistent. Among them, the standardization of data is a well-known technology and will not be elaborated further;

[0089] When the difference evaluation value is less than the preset difference evaluation threshold, the corresponding moments are all regarded 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 regarded as the second moment. In this embodiment, the preset difference evaluation threshold is set 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, at the first moment, the coupling abnormality degree of the abnormal patch should be greater, and the coupling rationality degree of the abnormal patch should be smaller; at the second moment, the coupling abnormality degree of the abnormal patch should be smaller, and the coupling rationality degree of the abnormal patch should be greater. In order to analyze the coupling rationality of the abnormal patch in the current time period more accurately and quickly, the time periods corresponding to the continuous first moments and the continuous second moments 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 coupling rationality of the abnormal patch in each independent time period, and then accurately obtain the coupling rationality of the abnormal patch in the current time period. Therefore, according to the size and fluctuation of the coupling abnormality degree of the abnormal patch in each independent time period, as well as the size 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;

[0090] In a feasible implementation manner of this embodiment, the method for obtaining the reasonable contribution degree is as follows: for any independent time period, obtain the variance of the coupling abnormality degree of the abnormal patch in this independent time period as the reference variance; obtain the mean value of all the coupling abnormality degrees of the abnormal patch in this independent time period as the reference coupling abnormality value; when both the reference variance and the reference coupling abnormality value are smaller, it indicates that the coupling effect of the abnormal patch in this independent time period is better; in order to analyze the coupling effect more accurately, further obtain the mean value of all the difference evaluation values of the abnormal patch in this independent time period as the reference difference value; the greater the reference difference value, the more it indicates that the coupling effect of the abnormal patch in this independent time period is better. In order to accurately analyze the coupling effect of the abnormal patch in this independent time period, the reasonable contribution degree of the abnormal patch in this independent time period is obtained according to the reference variance, the reference coupling abnormality value and the reference difference value; among them, both the reference variance and the reference coupling abnormality value have a negative correlation with the reasonable contribution degree, and the reference difference value has a positive correlation with the reasonable contribution degree;

[0091] Among them, the calculation formula of the 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 abnormality value; is the reference difference value; norm is the normalization function. In this embodiment, it is set that is 0.1, and the implementer can set the size according to the actual situation, which is not limited here;

[0092] Take the mean value of all reasonable contribution degrees 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 abnormal patches with more equal first eigenvalues are more likely to be the abnormal patches in the same treatment site. Therefore, in this embodiment, the first eigenvalue of each abnormal patch is obtained, and according to the size of the first eigenvalue, the abnormal patches are divided into abnormal patch categories by the DBSCAN density clustering algorithm; among them, an abnormal patch category represents the abnormal patches included in a treatment site. Among them, the DBSCAN density clustering algorithm is a well-known technology and will not be elaborated here. It should be noted that in this embodiment, the neighborhood distance threshold in the DBSCAN density clustering algorithm is set to 0.3, and the minimum number of samples in the neighborhood is 3. The implementer can set the neighborhood distance threshold and the minimum number of samples in the neighborhood according to the actual situation, which is not limited here; thus, the abnormal patches in each treatment site are obtained;

[0093] For any normal patch, take the mean value of all coupling abnormal degrees of the normal patch in the current time period as the second eigenvalue of the normal patch; obtain the second eigenvalues of all normal patches, and according to the size of the second eigenvalues, divide the normal patches into normal patch categories by the DBSCAN density clustering algorithm; among them, a normal patch category represents the normal patches included in a treatment site; thus, the normal patches in each treatment site are obtained;

[0094] It is known that there are obvious differences in the coupling abnormal degrees between the normal patches and the abnormal patches belonging to the same treatment site. Therefore, in this embodiment, according to the differences in the coupling abnormal degrees between each abnormal patch category and each normal patch category, the abnormal patches and normal patches belonging to the same treatment site are obtained. The specific operations are as follows:

[0095] For any abnormal patch category, obtain the average value of all coupling abnormality degrees of all abnormal patches in the abnormal patch category during the current time period as the first coupling abnormality value of the abnormal patch category; obtain the average value of all coupling abnormality degrees of all normal patches in each normal patch category during 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 as the first reference value; take the normal patches in the normal patch category corresponding to the largest first reference value and the abnormal patches in the abnormal patch category as the abnormal patches and normal patches of the same treatment site. It should be noted that after a certain normal patch category is matched with a certain abnormal patch category, it will no longer participate in the subsequent division of abnormal patches and normal patches of the same treatment site.

[0096] In actual situations, if the number of abnormal patches in a certain treatment site is too large, the degree of interference on the ultrasonic patches in that treatment site will be too high. At this time, the ultrasonic data of the ultrasonic patches in that treatment site has little reference significance. For example, due to very irregular operations or all the ultrasonic patches in that treatment site having material defects or malfunctions. Therefore, in another embodiment of this embodiment, for any treatment site, when the number of abnormal patches in that treatment site is greater than half of the total number of ultrasonic patches in that treatment site, it indicates that there are too many abnormal patches in that treatment site. The abnormal patches in that treatment site may be caused by avoidable factors such as very irregular operations or all the ultrasonic patches in that treatment site having material defects or malfunctions. In order to reduce the degree of interference of avoidable factors, the ultrasonic patches in that treatment site are all replaced, and at the same time, the operation rules are improved. Then, the abnormal patch analysis is performed again on the treatment site after replacing the ultrasonic patches 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.

[0097] Step S4: According to the ultrasonic data differences 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, correct the ultrasonic data of each abnormal patch at each moment to obtain the corrected ultrasonic data of each abnormal patch at each moment.

[0098] It is known that when the degree of coupling anomaly of a certain abnormal patch at a certain moment within the current time period is greater, it indicates that the possibility of the ultrasonic data of the abnormal patch being abnormal at that moment is greater, and the degree to which the ultrasonic data of the abnormal patch needs to be corrected at that moment should be greater; at the same time, the trend of correction of the ultrasonic data of the abnormal patch at that moment should be more towards the ultrasonic data of the normal patch within the treatment site where the abnormal patch is located at that moment. Therefore, in this embodiment, according to the difference in ultrasonic data between each abnormal patch and each normal patch within each treatment site at each moment, and the degree of coupling anomaly 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.

[0099] Preferably, in a realizable manner of this embodiment, the method for obtaining the corrected ultrasonic data is as follows: for any abnormal patch in any treatment site and any moment within the current time period, obtain the average value of the ultrasonic data of all normal patches in the treatment site at that moment as the reference ultrasonic data; take the difference between the ultrasonic data of the abnormal patch at that moment and the reference ultrasonic data as the correction reference value; take the product of the degree of coupling anomaly of the abnormal patch at that moment and the correction reference value as the adjusted ultrasonic data of the abnormal patch at that moment; take 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.

[0100] Thus, the corrected ultrasonic data of each ultrasonic patch at each moment within the current time period is obtained.

[0101] Step S5: Obtain electro-ultrasonic parameters based on the corrected ultrasonic data.

[0102] Specifically, input the corrected ultrasonic data of each abnormal patch at each moment within the current time period and the ultrasonic data of each normal patch at each moment within the current time period into the treatment system of the electro-ultrasonic therapy instrument. The treatment system will automatically and accurately obtain each electro-ultrasonic parameter, ensuring that the ultrasonic energy during the treatment process can be fully and effectively transmitted to the treatment site, improving the treatment effect of the treatment site, enhancing the patient experience, and avoiding the problem of unsatisfactory treatment effect caused by poor coupling effect of the ultrasonic patch.

[0103] In summary, this embodiment obtains ultrasonic data, temperature data, and electric power data of the ultrasonic patch; based on the ultrasonic data and temperature data, obtains the degree of coupling abnormality of the ultrasonic patch, and classifies the ultrasonic patch into an abnormal patch and a normal patch; based on the difference between the ultrasonic data and the electric power data of the abnormal patch, as well as the degree of coupling abnormality, obtains abnormal patches and normal patches belonging to the same treatment site; based on the difference in ultrasonic data between the abnormal patch and the normal patch within each treatment site, and the degree of coupling abnormality of the abnormal patch, obtains the corrected ultrasonic data of the abnormal patch, and further obtains the electro-ultrasonic parameters. By accurately obtaining the corrected ultrasonic data of each abnormal patch at each moment in real time, the present invention improves the accuracy of real-time adjustment of various electro-ultrasonic parameters, which is beneficial to the effective treatment of patients by the electro-ultrasonic therapeutic apparatus.
