DETAILED DESCRIPTION

[0017] In order to further illustrate the technical means and effects taken by the present application to achieve the predetermined inventive objectives, the specific implementation, structure, features and effects of the control method for vaginal irrigation and dilation based on multi-modal data according to the present application are described in detail below in combination with the drawings and preferred embodiments. In the following description, different "one 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.

[0018] Unless otherwise defined, 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 application belongs.

[0019] The specific scheme of the control method for vaginal irrigation and dilation based on multi-modal data provided by the present application is specifically described below in combination with the drawings.

[0020] Embodiment 1:

[0021] The present application proposes a control method for vaginal irrigation and dilation based on multi-modal data, please refer to Figure 1 which shows a schematic flowchart of a control method for vaginal irrigation and dilation based on multi-modal data according to one embodiment of the present application, which includes the following steps: Step S1: Obtain the pelvic floor muscle electrical signal, pH value and irrigation flow rate data of each patient at each time during the vaginal irrigation and dilation process, as well as the basic information of each patient; wherein the vaginal irrigation and dilation process includes an initial stage and an irrigation and dilation stage.

[0022] Specifically, it is known that the main working principle of vaginal irrigation and dilation is that the vaginal dilation and cleaning device expands the vagina and then uses a specific cleaning liquid to irrigate the vagina. With the increase of expansion time, the muscles in the patient's vagina will be continuously stretched. When the muscle tone increases, the pelvic floor muscle contraction force will increase, which will squeeze the blood vessels of the vaginal wall, causing the blood flow of the mucosal layer to decrease, reducing the mucosa's tolerance to mechanical stimulation. At this time, if the irrigation flow rate is too high, the high-speed impact is easy to cause microvascular rupture, causing damage to the vagina. The higher the muscle tone, the greater the probability of rupture when subjected to a higher flow rate. In addition, the pH value in the vagina is an important indicator reflecting the balance of the vaginal environment, and the change of pH value directly affects the health status of the vaginal mucosa and the tolerance to cleaning operation. In order to avoid the patient's vaginal loss during the vaginal irrigation and dilation process, it is necessary to analyze the pelvic floor muscle tone and the change of pH value in the vagina in real time to ensure accurate control of the vaginal irrigation flow rate.

[0023] This embodiment uses a highly sensitive pelvic floor electromyography sensor and a fast-response pH sensor to acquire pelvic floor electromyography signals and pH values ​​at each moment during each vaginal irrigation and dilation process. It also acquires irrigation flow rate data for each patient at each moment during the process. This embodiment sets the frequency for collecting pelvic floor electromyography signals, pH values, and irrigation flow rate data to 50 Hz. The frequency can be adjusted by the user based on actual circumstances and is not limited here. This embodiment uses flexible electrodes for the pelvic floor electromyography sensor, sets the pH sensor's measurement range to 3.0-6.0 with an accuracy of ±0.1, and places the pH sensor on top of the irrigation head to better detect the pH value within the vaginal environment. It should be noted that the aforementioned patients include both historical and current patients, with the historical patients all experiencing no injuries during the vaginal irrigation and dilation process. Furthermore, this embodiment assumes that the complete vaginal irrigation and dilation process includes an initial phase and an irrigation and dilation phase. The initial phase is used to analyze information about the patient's vaginal interior before irrigation, and no irrigation flow rate data is available during the initial phase. The irrigation and dilation phase is used to analyze information about the patient's vaginal interior during the irrigation and dilation process.

[0024] In order to subsequently find historical patients similar to the current patient and better control the flushing flow rate of the flushing fluid during the vaginal flushing and dilation process of the current patient, this embodiment obtains basic information of each patient, wherein the basic information includes the patient's age, body mass index, number of pregnancies, and disease type code; it should be noted that the rule of disease type coding is to define bacterial vaginosis as coded 1, Trichomonas vaginitis as coded 2, and preoperative cleaning as coded 3.

[0025] Step S2: Based on the similarity between the basic information of the current patient and the historical patients, the matching historical patients of the current patient are obtained; based on the peak amplitude and irrigation flow rate data of the pelvic floor electromyography signal of each matching historical patient in each preset time period during the irrigation and expansion phase, the electromyography influence degree corresponding to each preset time period of the current patient is obtained.

[0026] Specifically, in order to analyze the current patient's pelvic floor muscle tension in real time, the embodiment first acquires the matching historical patient of the current patient according to the similarity of the basic information of the current patient and the historical patient. The matching historical patient can be the patient similar to the current patient in the process of vaginal irrigation and expansion by default, because the vaginal conditions of the current patient and the matching historical patient are similar. Then, the influence of the current patient's pelvic floor muscle tension on the irrigation flow rate can be indirectly determined in real time by analyzing the pelvic floor muscle electrical signal and the irrigation flow rate data of each matching historical patient in the process of vaginal irrigation and expansion. Therefore, the embodiment acquires the muscle electrical influence degree corresponding to each preset time period of the current patient according to the peak amplitude of the pelvic floor muscle electrical signal and the irrigation flow rate data of each matching historical patient in each preset time period in the process of irrigation and expansion. The smaller the muscle electrical influence degree, the more tense the current patient's pelvic floor muscle in the corresponding preset time period, the stronger the muscle restriction should be, and the greater the degree of reducing the irrigation flow rate is needed to avoid vaginal damage. The peak amplitude is a known content and will not be described here.

[0027] Preferably, in one implementation manner of the embodiment, the method for acquiring the matching historical patient is: converting the basic information of each patient into a vector as the feature vector of each patient; wherein the elements at the same position in each feature vector correspond to the same kind of basic information. Then, the cosine similarity of the feature vector of the current patient and each historical patient is acquired, which is used as the similarity degree; the greater the similarity degree, the more similar the corresponding historical patient and the current patient, and then the embodiment sets the preset similarity degree threshold value as 0.5, and the implementer can set the size of the preset similarity degree threshold value according to the actual situation, which is not limited here. When the similarity degree is greater than the preset similarity degree threshold value, the corresponding historical patient is used as the matching historical patient of the current patient. The method for acquiring the cosine similarity is a known technology and will not be described here.

[0028] Preferably, in one implementation mode of the present embodiment, the method for obtaining the degree of myoelectric influence is: each flushing dilation phase of each matched historical patient is sequentially divided into each preset time period according to time sequence; the present embodiment sets the length of the preset time period as 1 second, and the implementer can set the size of the preset time period according to the actual situation, which is not limited herein. When the peak amplitude of the pelvic floor myoelectric signal corresponding to a certain preset time period of a certain matched historical patient is larger, it indicates that the pelvic floor muscle of the matched historical patient in the preset time period is more tense, and then the present embodiment obtains the muscle tension degree corresponding to each preset time period of each matched historical patient according to the peak amplitude of the pelvic floor myoelectric signal corresponding to each preset time period of each matched historical patient. The specific method for obtaining the muscle tension degree is: for any patient, first, the peak amplitude of the pelvic floor myoelectric signal corresponding to the maximum voluntary contraction of the pelvic floor muscle of the patient in the comfortable state for a preset length of time is taken as the maximum voluntary contraction amplitude of the patient; the present embodiment sets the preset length of time as 5 seconds, and the implementer can set the length of time according to the actual situation, which is not limited herein. For any preset time period of the patient, the ratio of the peak amplitude of the pelvic floor myoelectric signal in the preset time period to the maximum voluntary contraction amplitude is taken as the muscle tension degree corresponding to the preset time period of the patient. Because the contraction degree of the pelvic floor muscle of different patients is different, the present embodiment obtains the maximum voluntary contraction amplitude of each patient, so as to more accurately analyze the muscle tension degree corresponding to each preset time period of each patient; the value range of the muscle tension degree is 0 to 1, when the muscle tension degree is 0, it represents that the pelvic floor muscle is completely relaxed; when the muscle tension degree is 1, it represents that the pelvic floor muscle is highly tense. By obtaining the muscle tension degree, the abstract pelvic floor myoelectric signal can be converted into an intuitive quantitative parameter, which can accurately reflect the change of the pelvic floor muscle tension degree in real time; In order to accurately and efficiently determine the flushing flow rate corresponding to different muscle tension degrees, and then preset the interval range of the muscle tension degree division, the present embodiment sets the interval range of the muscle tension degree division as , and the implementer can set the interval range of the muscle tension degree division according to the actual situation, which is not limited herein. The mean value of all flushing flow rate data in the preset time period of the matched historical patient corresponding to each muscle tension degree in each interval range is taken as the safe flow rate data of each interval range; for example, taking the interval range of as an example, the mean value of all flushing flow rate data in the preset time period of the matched historical patient corresponding to the muscle tension degree in the interval range of is taken as the safe flow rate data of Corresponding safe flow rate data. The ratio of the safe flow rate data in each interval to the preset baseline flow rate data is used as the degree of myoelectric influence corresponding to the degree of muscle tension in the corresponding interval. It should be noted that the preset baseline flow rate data is set by the doctor according to the type of disease. For example, the preset baseline flow rate data for preoperative cleaning is set to 100 ml / min, which is not limited here. Then, the myoelectric influence degree corresponding to the muscle tension degree corresponding to each preset time period of the current patient is used as the myoelectric influence degree corresponding to each preset time period of the current patient; wherein the preset time period of the current patient includes the preset time period of the current patient in the initial stage.

[0029] It should be noted that if there is no matching historical patient for the current patient, the negative correlation result of the muscle tension level corresponding to each preset time period of the current patient is used as the myoelectric influence level corresponding to each preset time period of the current patient. In this embodiment, the result of subtracting the muscle tension level from 1 is used as the negative correlation result of the muscle tension level.

[0030] At this point, the myoelectric influence degree corresponding to each preset time period of the current patient is obtained.

[0031] Step S3: Obtain the pH impact degree of the current patient at each moment based on the difference between the pH value of the current patient at each moment and the normal pH value range of the vagina, as well as the change of the pH value within the preset range time period at each moment.

[0032] Specifically, a large number of medical studies have shown that the pH value in the vagina of healthy women is usually maintained in the weakly acidic range of 3.8-4.5. The normal pH value range of the vagina is conducive to the growth of beneficial bacteria such as lactobacilli, inhibits the growth of harmful bacteria, and is conducive to maintaining the balance of vaginal microecology. When the pH value in the vagina exceeds the normal pH value range of the vagina, the tolerance of the mucosa will decrease, and the flushing flow rate needs to be reduced to prevent vaginal damage. At the same time, when the pH value changes rapidly, it may indicate that an acute infection requires a priority response. Therefore, this embodiment obtains the pH impact degree of the current patient at each moment based on the difference between the pH value of the current patient at each moment and the normal pH value range of the vagina, as well as the change in pH value within the preset domain time period at each moment. The greater the pH impact degree, the more the pH value of the current patient at the corresponding moment deviates from the normal pH value range of the vagina, and the smaller the flushing flow rate is required.

[0033] Preferably, in one implementation mode of the present embodiment, the method for obtaining the degree of pH influence is as follows: taking the mean of the maximum pH value and the minimum pH value in the normal pH value range of the vagina as the normal reference pH value; taking the absolute value of the difference between the maximum pH value in the normal pH value range of the vagina and the normal reference pH value as the pH value tolerance degree; taking the absolute value of the difference between the pH value of the current patient at each time and the normal reference pH value as the pH value deviation degree of the current patient at each time; when the pH value deviation degree is less than or equal to the pH value tolerance degree, the pH value of the current patient at the corresponding time is within the normal pH value range of the vagina; and then for any time of the current patient, the ratio of the pH value deviation degree at the time to the pH value tolerance degree is taken as the pH value abnormality degree of the current patient at the time. The present embodiment sets the preset abnormality threshold value as 1, and when the pH value abnormality degree is greater than the preset abnormality threshold value, it indicates that the pH value at the time is abnormal. In order to accurately analyze the abnormal situation of the pH value at the time, first, the variance of the absolute values of the differences between the pH values of the current patient at all adjacent two times in the preset neighborhood time period of the time is obtained as the pH value change degree of the current patient at the time; wherein the preset neighborhood time period of the time is a time period corresponding to a time length of 0.2 seconds with the time as the terminal time, and the implementer can set the time length of the preset neighborhood time period of the time according to the actual situation, which is not limited herein, but the terminal time of the preset neighborhood time period of the time must be the time. The greater the pH value change degree, the more likely the current patient has an acute change in the pH value at the time, the greater the risk of acute infection, and the more need for priority response; then the difference between the pH value abnormality degree of the current patient at the time and the preset abnormality threshold value is obtained as the first difference; the greater the first difference, the more abnormal the pH value of the current patient at the time; and then the product of the first difference and the pH value change degree is normalized as the pH influence degree of the current patient at the time. The present embodiment normalizes the product of the first difference and the pH value change degree by the norm normalization function; When the pH value abnormality degree is less than or equal to the preset abnormality threshold value, it indicates that the pH value at the time is not abnormal, i.e. within the normal pH value range of the vagina, and 0 is taken as the pH influence degree of the current patient at the time.

[0034] Thus, the pH influence degree of the current patient at each time is obtained.

[0035] Step S4: Real-time obtaining the flow rate adjustment weight of the current patient according to the muscle influence degree and the pH influence degree in the time period corresponding to the time when the vaginal irrigation and dilation process starts to the current time.

[0036] It is known that the smaller the myoelectricity influence degree and the greater the pH influence degree of the current patient are, the more necessary it is to reduce the irrigation flow rate to avoid damage to the vagina, and thus the embodiment acquires the flow rate adjustment weight of the current patient in real time according to the myoelectricity influence degree and the pH influence degree of the current patient in the time period corresponding to the time from the beginning of the vaginal irrigation and expansion process of the current patient to the current time, which is beneficial to accurately control the irrigation flow rate of the current patient in real time.

[0037] Preferably, in an implementable manner of the embodiment, the method for acquiring the flow rate adjustment weight is as follows Figure 2 which shows a flowchart of a method for acquiring a flow rate adjustment weight provided by the embodiment, and the method comprises the following steps: Step S201: Acquire the initial state muscle analysis value of the current patient.

[0038] Considering that the time nodes corresponding to the myoelectricity influence degree and the pH influence degree are different, the embodiment takes the end time of each preset time period of the current patient as the target time of the current patient, and takes the myoelectricity influence degree corresponding to each preset time period of the current patient as the myoelectricity influence degree at each target time of the current patient. In order to accurately control the irrigation flow rate subsequently, the embodiment takes the pH influence degree as the horizontal axis and the myoelectricity influence degree as the vertical axis to construct a two-dimensional coordinate system, so as to accurately analyze the relationship between the myoelectricity influence degree and the pH influence degree, which is beneficial to accurately determine the adjustment weight of the myoelectricity influence degree and the pH influence degree subsequently, and to accurately acquire the flow rate adjustment weight. Considering that the original vaginal pH environment and the endurance of the pelvic floor muscles of different patients are different in actual situations, the embodiment acquires the initial state muscle analysis value of the current patient according to the coordinate points corresponding to the myoelectricity influence degree and the pH influence degree of the current patient at each target time in the initial stage in the two-dimensional coordinate system. The greater the initial state muscle analysis value is, the more sensitive the muscles of the vagina of the current patient are to the fluctuation of the pH value before irrigation.

[0039] In an implementable manner of the embodiment, the method for acquiring the initial state muscle analysis value is as follows: take the coordinate points corresponding to the myoelectricity influence degree and the pH influence degree of the current patient at each target time in the initial stage in the two-dimensional coordinate system as initial coordinate points; acquire the straight line corresponding to the initial coordinate points by principal component analysis algorithm as an initial reference straight line, which is beneficial to accurately analyze the relationship between the myoelectricity influence degree and the pH influence degree; and then take the slope of the initial reference straight line as the initial state muscle analysis value of the current patient. The method for acquiring the straight line by the principal component analysis algorithm is a known technology and will not be described herein.

[0040] Step S202: Acquire the current muscle analysis value of the current patient.

[0041] In order to accurately analyze the relationship between the myoelectricity influence degree and the pH influence degree of the current patient in the flushing process in real time, so as to accurately determine the adjustment weight of the myoelectricity influence degree and the pH influence degree in real time, and to accurately control the flushing flow rate of the current patient in the flushing process in real time, the embodiment obtains the current muscle analysis value of the current patient according to the coordinate points corresponding to the myoelectricity influence degree and the pH influence degree of the current patient at each target time point in the flushing expansion stage up to the current time point; wherein the current time point is in the flushing expansion stage of the current patient. Through the current muscle analysis value, the relationship between the myoelectricity influence degree and the pH influence degree of the current patient is accurately analyzed in real time.

[0042] In an implementable manner of the embodiment, the method for obtaining the current muscle analysis value is: performing curve fitting on the coordinate points corresponding to the myoelectricity influence degree and the pH influence degree of the current patient at each target time point in the flushing expansion stage up to the current time point in a two-dimensional coordinate system to obtain a reference curve; wherein the method for fitting the curve is a known technology and will not be described in detail. The first derivative of the coordinate point corresponding to the last target time point of the current patient in the reference curve up to the current time point is taken as the current muscle analysis value of the current patient.

[0043] Step S203: Real-time acquisition of the dynamic reference weight of the current patient.

[0044] In order to accurately determine the adjustment weight of the myoelectricity influence degree of the current patient in real time, the embodiment obtains the dynamic reference weight of the current patient at the last target time point up to the current time point according to the difference between the current muscle analysis value and the initial state muscle analysis value. The greater the dynamic reference weight is, the more sensitive the change of the current myoelectricity influence degree is, and the greater the influence of the myoelectricity influence degree on the flushing flow rate is.

[0045] In an implementable manner of the embodiment, the difference between the current muscle analysis value and the initial state muscle analysis value is normalized to obtain the dynamic reference weight of the current patient at the last target time point up to the current time point. The embodiment normalizes the difference between the current muscle analysis value and the initial state muscle analysis value by using a norm normalization function.

[0046] Step S204: Real-time acquisition of the flow rate adjustment weight of the current patient.

[0047] The greater the dynamic reference weight, the smaller the adjustment weight of the pH influence degree, and then the embodiment will multiply the dynamic reference weight at the last target time of the current patient up to the current time by the muscle influence degree to obtain a first regulation factor; multiply the negative correlation result of the dynamic reference weight at the last target time of the current patient up to the current time by the pH influence degree to obtain a second regulation factor; wherein the embodiment takes 1 minus the dynamic reference weight as the negative correlation result of the dynamic reference weight; and then adds the first regulation factor and the second regulation factor to obtain the flow rate adjustment weight at the last target time of the current patient up to the current time.

[0048] It should be noted that, because the length of the preset time period is 1 second, the embodiment obtains the flow rate adjustment weight for the current patient every second as the irrigation dilation progresses.

[0049] Step S5: Real-time control of the irrigation flow rate in the vaginal irrigation dilation process of the current patient based on the flow rate adjustment weight.

[0050] Specifically, after obtaining the flow rate adjustment weight of the current patient in real time, the irrigation flow rate in the vaginal irrigation dilation process of the current patient can be controlled in real time, that is, the irrigation flow rate data is adjusted to modified irrigation flow rate data that conforms to the current pH environment and pelvic floor muscle state in the vagina through linear regulation. The method for obtaining the modified irrigation flow rate data is: multiplying the flow rate adjustment weight at the last target time of the current patient up to the current time by the irrigation flow rate data to obtain the modified irrigation flow rate data at the last target time of the current patient up to the current time; and then real-time control of the irrigation flow rate in the vaginal irrigation dilation process of the current patient is realized. It should be noted that the initial irrigation flow rate data is set by professionals according to the actual disease type, which is not limited herein, and in order to ensure the irrigation efficiency, the lower limit of the initial irrigation flow rate data is set to 0.5 ml / min in the embodiment, and the implementer can set the initial irrigation flow rate data according to the actual situation, which is not limited herein.

[0051] In addition, when the flow rate adjustment weight is greater than 1, it indicates that the flushing flow rate needs to be increased; when the flow rate adjustment weight is less than or equal to 1, it indicates that the flushing flow rate needs to be reduced; it is known that the inflation volume of the flushing head before the vagina is flushed and expanded has been set in advance, when the flushing flow rate is increased, the inflation volume of the flushing head will automatically increase, which is easy to cause damage to the vagina. In order to avoid the damage to the vagina caused by the vagina flushing and expanding device, and then when the flow rate adjustment weight is greater than 1, the product of the preset volume correction weight and the inflation volume of the current flushing head is taken as the corrected inflation volume of the current flushing head, so as to avoid that the inflation volume of the flushing head is too large, and at the same time, the flushing efficiency is not excessively affected; wherein, the preset volume correction weight is set to 0.95 in the embodiment, and the implementer can set the preset volume correction weight according to the actual situation, which is not limited herein, but the preset volume correction weight is greater than 0 and less than 1. When the flow rate adjustment weight is less than or equal to 1, the inflation volume of the flushing head does not need to be corrected. Considering that there is a certain delay in the change of the vagina environment after the flushing flow rate is changed in the actual situation, and in order to avoid that the adjustment frequency of the flushing flow rate data is too high to reduce the robustness of the system, and then the flushing flow rate data is corrected once every 2 minutes in the embodiment, and the implementer can set the time interval between the adjacent two corrections of the flushing flow rate data according to the actual situation, which is not limited herein.

[0052] It should be noted that when the flow rate adjustment weight is less than 0.2 for 3 seconds, or the pH value is greater than 5.5, or the muscle tension degree is greater than 0.9, it indicates that the vagina is in an extreme risk state at this time, and the vagina expansion and cleaning device automatically suspends flushing and sends an alarm to the medical staff for timely processing. The conditions corresponding to the above extreme risk state can be set according to the actual situation, which is not limited herein.

[0053] In summary, the embodiment obtains the pelvic floor muscle electrical signal, the pH value and the flushing flow rate data of the patient in the process of vaginal flushing and expansion; according to the pelvic floor muscle electrical signal and the flushing flow rate data of the matching historical patient of the current patient in the flushing and expansion stage, the muscle electrical influence degree of the current patient is obtained; according to the difference between the pH value of the current patient at each time and the normal pH value range of the vagina, and the change of the pH value in each time preset field time period, the pH influence degree of the current patient is obtained; according to the muscle electrical influence degree and the pH influence degree, the flow rate adjustment weight of the current patient is obtained in real time, and the flushing flow rate of the current patient in the process of vaginal flushing and expansion is controlled. The present application accurately obtains the flow rate adjustment weight in real time, so as to accurately adjust the flushing flow rate, and effectively avoid the damage to the vagina in the process of flushing and expansion.
