[0001] The present invention relates to the field of urine detection, and in particular to a diaper urine detection method and system based on an electrochemical sensor. Background Art

[0002] Diapers are disposable underwear designed for infants and adults who cannot take care of themselves to absorb their urine. By integrating electrochemical sensors in diapers, various indicators in the urine of relevant people can be tested, thereby evaluating the urine condition of relevant people and the human body's metabolic level or kidney function, etc., which is of great significance for infants and people who cannot take care of themselves.

[0003] In the related art, various electrochemical sensors integrated in diapers are usually used to collect concentration data or content data of various indicators of urine on the diapers, and the urine condition of the person to be tested is evaluated by analyzing the changes in the concentration data of various indicators. However, due to the differences in the daily water intake of the persons to be tested, the urine is subjected to different degrees of dilution effect, resulting in deviations in the indicator concentration data collected by the electrochemical sensors integrated in the diapers, thereby reducing the accuracy of the detection of the urine condition of the persons to be tested. Summary of the invention

[0004] In order to solve the technical problem that the index concentration data collected by the electrochemical sensor integrated in the diaper has deviations, thereby reducing the accuracy of the urine condition detection of the tested person, the purpose of the present invention is to provide a diaper urine detection method and system based on an electrochemical sensor, and the technical scheme adopted is as follows: The present invention proposes a diaper urine detection method based on an electrochemical sensor, the method comprising: Obtain the concentration data of different urine test indicators and the urination duration of each urination of the test person during each urination within a preset time period, and at the same time obtain the water intake data of the test person during each day; Taking any day within the preset time period as the target day, obtaining the initial concentration value of each urine detection index in the target day according to the concentration data of the same urine detection index of all urinations in the target day and the urination duration of each urination; obtaining the urine dilution degree of the target day according to the difference in the water intake data between the target day and other days except the target day within the preset time period; adjusting the initial concentration value of each urine detection index in the target day based on the urine dilution degree to obtain the actual concentration value of each urine detection index in the target day; According to the change of the true concentration value of the same urine test index on each day within a preset time period, the concentration fluctuation degree of each urine test index is obtained; the concentration fluctuation degrees of all urine test indexes are comprehensively analyzed to obtain the urine evaluation factor of the person to be tested; Based on the urine evaluation factor, the urine condition of the person to be tested is evaluated.

[0005] Furthermore, the step of obtaining the initial concentration value of each urine test index on the target day includes: On the target day, the duration of each urination is used as the numerator, the cumulative value of the duration of all urinations is used as the denominator, and the ratio is used as the proportion of the duration of each urination on the target day; Taking any urine test index as the target urine test index, taking the product value of the duration ratio of each urination on the target day and the concentration data of the target urine test index of each urination as the adjusted concentration data of the target urine test index of each urination on the target day; The average value of the adjusted concentration data of the target urine detection index of all urinations on the target day is used as the initial concentration value of the target urine detection index on the target day.

[0006] Further, obtaining the urine dilution degree of the target day includes: In a preset time period, other days except the target day are used as reference days, and the difference between the water intake data of the target day and each reference day is used as the water intake difference value between the target day and each reference day; The cumulative value of the water intake difference between the target day and all reference days is taken as the comprehensive water intake difference value of the target day; Obtaining a deviation of the drinking water amount on the target day according to a difference between the drinking water amount data on the target day and the overall level of the drinking water amount data on all days within a preset time period; The product of the water intake deviation and the comprehensive water intake difference value on the target day is normalized to obtain the urine dilution degree on the target day, wherein the value range of the urine dilution degree is .

[0007] Furthermore, obtaining the deviation of the water intake on the target day includes: The average value of the water intake data of all days in the preset time period is taken as the overall water intake of the preset time period; The absolute value of the difference between the water intake data of the target day and the overall water intake is added to a preset adjustment parameter to obtain a deviation of the water intake on the target day.

[0008] Furthermore, obtaining the true concentration value of each urine test indicator on the target day includes: The product of the urine dilution degree on the target day and the initial concentration value of the target urine detection index is used as the concentration adjustment amount of the target urine detection index on the target day; The sum of the initial concentration value and the concentration adjustment amount of the target urine detection index on the target day is used as the actual concentration value of the target urine detection index on the target day.

[0009] Furthermore, obtaining the concentration fluctuation degree of each urine detection index includes: Within a preset time period, according to the difference in the actual concentration value of the target urine detection index between each day and the next adjacent day, a first concentration fluctuation parameter of the target urine detection index is obtained; The absolute value of the difference between the actual concentration value of the target urine detection index and the standard concentration value of the target urine detection index in each day is used as the concentration deviation value of the target urine detection index in each day, and the average value of the concentration deviation values ​​of the target urine detection index in all days within a preset time period is used as the second concentration fluctuation parameter of the target urine detection index; The first concentration fluctuation parameter and the second concentration fluctuation parameter are integrated and normalized to obtain the concentration fluctuation degree of the target urine detection index.

[0010] Furthermore, the first concentration fluctuation parameter of the target urine detection index is obtained including: The absolute value of the difference between the actual concentration value of the target urine detection index on each day and the next adjacent day is used as the concentration change of the target urine detection index on each day; The average value of the concentration change of the target urine detection index in all days within the preset time period is used as the first concentration fluctuation parameter of the target urine detection index.

[0011] Furthermore, the step of obtaining the urine evaluation factor of the person to be tested includes: The average value of the concentration fluctuation degree of all urine test indicators is used as the urine evaluation factor of the person to be tested.

[0012] Furthermore, the evaluating the urine condition of the person to be tested based on the urine evaluation factor includes: If the urine evaluation factor is less than the preset evaluation threshold, the urine quality of the person to be tested is good; otherwise, the urine quality of the person to be tested is poor.

[0013] The present invention also proposes a diaper urine detection system based on an electrochemical sensor, the system comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor implementing any one of the steps of a diaper urine detection method based on an electrochemical sensor when executing the computer program.

[0014] The present invention has the following beneficial effects: The present invention takes into account that the index concentration data collected by the electrochemical sensor integrated in the diaper has deviations, thereby reducing the accuracy of the urine condition detection of the person to be tested. Therefore, the present invention first obtains the concentration data of different urine detection indicators of each urination of the person to be tested within a preset time period every day and the urination duration of each urination, and simultaneously obtains the water drinking volume data of the person to be tested every day. Subsequently, various data can be comprehensively analyzed to improve the accuracy of the urine condition detection of the person to be tested. Since the person to be tested may urinate multiple times within a day, there are slight differences in the concentration data of the same urine detection indicator in the urine of different urinations. At the same time, the users of diapers are generally infants and young children who cannot urinate consciously or people who cannot take care of themselves. Each urination activity of these people may be a standard urination with a relatively long urination duration, or it may be an irregular urination with a relatively short urination duration. Therefore, it is necessary to combine each urination activity with the standard urination activity of each person to be tested. The duration of urination is used to improve the accuracy of analyzing the concentration data of the same urine test index of all urinations on the target day, and the initial concentration value is used to preliminarily reflect the average content level of each urine test index in the urine of the test person in multiple urinations on the target day; considering that there are large differences in the amount of water drunk by the test persons every day, and different amounts of water drunk will have different degrees of dilution effect on the urine, resulting in deviations in the calculated initial concentration data of the urine test index, therefore, the initial concentration value of the urine test index is adjusted by the obtained urine dilution degree to improve the accuracy of the urine test index concentration analysis, considering that the greater the fluctuation of the actual concentration value of the urine test index on each day, the worse the urine condition of the test person, therefore the concentration fluctuation degree can be used to reflect the fluctuation of the urine test index, and then the urine condition of the test person can be accurately evaluated by the urine evaluation factor.

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 the specific implementation, structure, features and effects of a diaper urine detection method and system based on an electrochemical sensor proposed by the present invention in combination 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 the diaper urine detection method and system based on electrochemical sensor provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1 , which shows a flow chart of a diaper urine detection method based on an electrochemical sensor provided by an embodiment of the present invention, the method comprising: Step S1: obtaining the concentration data of different urine test indicators and the urination duration of each urination of the person to be tested during a preset time period, and obtaining the water intake data of the person to be tested during each day.

[0021] Diapers are usually composed of four parts: a surface layer, a drainage layer, an absorption layer, and a waterproof bottom layer. When urine is discharged from the body, it first passes through the surface layer of the diaper to reach the drainage layer, and quickly diffuses around and enters the absorption layer, and finally reaches the waterproof bottom layer to prevent urine leakage.

[0022] There are a variety of urine detection indicators in urine, such as glucose, uric acid and bilirubin, etc. Therefore, the embodiment of the present invention first integrates the sensor for detecting the corresponding indicators into the absorption layer of the diaper, and uses various sensors to collect the concentration data of different urine detection indicators of each urination of the person to be tested within a preset time period every day, and then installs the flow monitor on the surface of the diaper. The flow monitor will detect the increase in urine flow and start timing. When urination ends, the urine flow decreases to zero or close to zero, and the monitor will stop timing. Therefore, the flow monitor can be used to collect the urination duration of each urination of the person to be tested. At the same time, the embodiment of the present invention also needs to use manual recording methods to count the daily water drinking data of the person to be tested within the preset time period. Subsequently, the accuracy of the urine condition detection of the person to be tested can be improved by comprehensive analysis of the various collected data.

[0023] The preset time period is set to 30 days, and the specific value of the preset time period can also be set by the implementer according to the specific implementation scenario, and is not limited here.

[0024] Step S2: taking any day within the preset time period as the target day, and obtaining the initial concentration value of each urine detection index in the target day according to the concentration data of the same urine detection index of all urinations in the target day and the urination duration of each urination; obtaining the urine dilution degree of the target day according to the difference in water intake data between the target day and other days except the target day within the preset time period; adjusting the initial concentration value of each urine detection index in the target day based on the urine dilution degree to obtain the true concentration value of each urine detection index in the target day.

[0025] The embodiment of the present invention first analyzes any day within a preset time period, and takes any day within the preset time period as a target day. The subsequent analysis method for other days is the same as the analysis method for the target day. Since the person to be tested may urinate multiple times within a day, there are slight differences in the concentration data of the same urine detection index in the urine of different urinations. Therefore, it is necessary to first analyze the overall level of the concentration data of the same urine detection index of all urinations in the target day. At the same time, the users of diapers are generally infants and young children who cannot urinate consciously or people who cannot take care of themselves. Each urination activity of these people can be It may be a regular urination with a relatively long urination time, or it may be an irregular urination with a relatively short urination time. Therefore, it is also necessary to analyze the overall level of concentration data of the same urine test index of all urinations in the target day in combination with the urination time of each urination, so as to improve the accuracy of the concentration data analysis of the same urine test index of all urinations in the target day, and preliminarily reflect the average content level of each urine test index in the urine of the test person in multiple urinations on the target day through the obtained initial concentration value. The initial concentration value can be further adjusted later to improve the accuracy of the urine condition detection of the test person.

[0026] Preferably, in one embodiment of the present invention, the method for obtaining the initial concentration value of each urine detection index on the target day specifically includes: First, on the target day, the duration of each urination is used as the numerator, the cumulative value of the urination duration of all urinations is used as the denominator, and the ratio is used as the proportion of the duration of each urination on the target day.

[0027] Then, taking any urine detection index as the target urine detection index, the greater the proportion of the duration of a certain urination in the target day, the longer the duration of the urination is, and further indicating that the urination activity of the person to be tested is a normative urination, then when calculating the initial concentration value of the target urine detection index in the subsequent calculation, the greater the reference value of the concentration data of the target urine detection index of the urination. Therefore, the product value of the duration proportion of each urination in the target day and the concentration data of the target urine detection index of each urination can be used as the adjusted concentration data of the target urine detection index for each urination in the target day, and the average value of the adjusted concentration data of the target urine detection index of all urinations in the target day can be used as the initial concentration value of the target urine detection index in the target day.

[0028] As an example, in one embodiment of the present invention, the expression of the initial concentration value of the target urine detection index in the target day can be specifically, for example, as follows:

[0029] in, represents the initial concentration value of the target urine test index on the target day; Indicates the target day Concentration data of target urine test indicators per urination; Indicates the target day Length of urination per urination; Indicates the target day Length of urination per urination; It represents the cumulative value of urination duration of all urinations in the target day; Indicates the target day Percentage of duration of urination; Indicates the target day Adjusted concentration data of target urine test indicators per urination; Indicates the number of urinations during the target day.

[0030] The same method as above can be used to obtain the initial concentration value of each urine test indicator every day. The initial concentration value preliminarily reflects the concentration level of a urine test indicator on that day. However, due to the large difference in the amount of water drunk by the test subjects every day, different amounts of water drunk will lead to differences in urine excretion, which will in turn produce different degrees of dilution effect on the urine, resulting in deviations in the calculation results of the initial concentration value, affecting the subsequent detection of the urine condition of the test subjects. If the amount of water drunk on that day is too much compared with other days, it means that the dilution effect of the urine on that day is relatively strong, and the calculation result of the initial concentration value is too small. If the amount of water drunk on that day is too little compared with other days, it means that the dilution effect of the urine on that day is relatively weak, and the calculation result of the initial concentration value is too large. Therefore, the difference in water drinking data between the target day and other days except the target day within the preset time period can be analyzed. The degree of dilution of urine obtained reflects the degree of dilution effect of urine on the target day. Subsequently, based on the degree of urine dilution, the initial concentration value of each urine test indicator on the target day can be adjusted to improve the accuracy of the concentration analysis of each urine test indicator.

[0031] Preferably, in one embodiment of the present invention, the method for obtaining the urine dilution degree of the target day specifically includes: See also Figure 2 , which shows a flow chart of a method for obtaining the urine dilution degree of a target day provided by an embodiment of the present invention.

[0032] Step S201: In a preset time period, other days except the target day are taken as reference days, the difference in water intake data between the target day and each reference day is taken as the water intake difference value between the target day and each reference day, and the accumulated value of the water intake difference values ​​between the target day and all reference days is taken as the comprehensive water intake difference value of the target day.

[0033] First, take the days other than the target day as reference days, calculate the difference in water intake data between the target day and each reference day, and obtain the water intake difference value between the target day and each reference day. If the water intake difference value is greater than 0 and the larger it is, the more water the target day drinks relative to each reference day; if the water intake difference value is less than 0 and the smaller it is, the less water the target day drinks relative to each reference day; then take the accumulated value of the water intake difference values ​​between the target day and all reference days as the comprehensive water intake difference value for the target day; if the comprehensive water intake difference value is greater than 0 and the larger it is, the more water the target day drinks relative to other days; if the comprehensive water intake difference value is less than 0 and the smaller it is, the less water the target day drinks relative to other days; subsequently, the urine dilution degree for the target day can be calculated based on the comprehensive water intake difference value.

[0034] Step S202: Obtain the deviation of the drinking water amount on the target day according to the difference between the drinking water amount data on the target day and the overall level of the drinking water amount data on all days within a preset time period.

[0035] At the same time, in order to improve the calculation accuracy of the urine dilution degree on the target day, it is also necessary to obtain the water intake deviation of the target day based on the difference between the water intake data on the target day and the overall level of water intake data of all days in the preset time period. The larger the water intake deviation, the greater the difference between the water intake on the target day and the overall level of water intake in the preset time period, which further indicates that the confidence level of the comprehensive water intake difference value of the target day calculated above is greater. Subsequently, the water intake deviation can be used as the weight of the comprehensive water intake difference value to improve the accuracy of the calculation of the urine dilution degree on the target day.

[0036] Preferably, in one embodiment of the present invention, the method for obtaining the deviation of the drinking water amount on the target day specifically includes: The average value of the drinking water volume data of all days in the preset time period is taken as the overall drinking water volume for the preset time period, and the absolute value of the difference between the drinking water volume data of the target day and the overall drinking water volume is added to the preset adjustment parameter to obtain the drinking water volume deviation of the target day.

[0037] Step S203: normalizing the product of the water intake deviation of the target day and the comprehensive water intake difference value to obtain the urine dilution degree of the target day.

[0038] The greater the difference in comprehensive water intake is, the more water the target day drinks compared to other days. The higher the dilution degree of urine on the target day is. The smaller the difference in comprehensive water intake is, the less water the target day drinks compared to other days. The lower the dilution degree of urine on the target day is. The greater the deviation of water intake is, the higher the confidence level of the analysis of the dilution degree of urine on the target day is. Therefore, the product of the deviation of water intake on the target day and the difference in comprehensive water intake can be normalized, and the calculation result can be limited to , the urine dilution degree of the target day is obtained, so that the initial concentration values ​​of urine detection indicators on different days can be adjusted in different directions according to the urine dilution degree.

[0039] In one embodiment of the present invention, the normalization processing can be specifically, for example, maximum and minimum value normalization processing, and the normalization in subsequent steps can all adopt maximum and minimum value normalization processing. In other embodiments of the present invention, other normalization methods can be selected according to the specific range of numerical values, which will not be described in detail.

[0040] As an example, in one embodiment of the present invention, the expression of the urine dilution degree on the target day may be specifically, for example, as follows:

[0041] in, Indicates the dilution degree of urine on the target day, with a range of ; Indicates the water intake data for the target day; Indicates Water intake data for a reference day; Indicates the target day and The difference in water intake between the reference days; It represents the difference value of comprehensive water intake on the target day; represents the number of reference days; Indicates the average value of the water intake data for all days in the preset time period, that is, the overall water intake in the preset time period; Indicates the deviation of water intake on the target day; Indicates preset adjustment parameters to prevent is 0, The value range is In one embodiment of the present invention, Set to 0.01, The specific value of can also be set by the implementer according to the specific implementation scenario and is not limited here; Represents the normalization function.

[0042] From the above analysis, it can be seen that the dilution effect of urine on that day is relatively strong, and the calculated result of the initial concentration value is too small. The dilution effect of urine on that day is relatively weak, and the calculated result of the initial concentration value is too large. Therefore, based on the dilution degree of urine on the target day, the initial concentration value of each urine detection index on the target day can be adjusted to obtain the true concentration value of each urine detection index on the target day, eliminate the interference of the difference in water intake on different days on the concentration analysis of urine detection indicators, and improve the accuracy of subsequent urine condition detection of the test personnel.

[0043] Preferably, in one embodiment of the present invention, the method for obtaining the true concentration value of each urine detection indicator in the target day specifically includes: The greater the urine dilution degree on the target day is, the smaller the calculated result of the initial concentration value is, and the more the initial concentration value needs to be increased; the smaller the urine dilution degree on the target day is, the larger the calculated result of the initial concentration value is, and the more the initial concentration value needs to be reduced. Therefore, the product of the urine dilution degree on the target day and the initial concentration value of the target urine detection index can be used as the concentration adjustment amount of the target urine detection index on the target day, and the sum of the initial concentration value and the concentration adjustment amount of the target urine detection index on the target day can be used as the actual concentration value of the target urine detection index on the target day.

[0044] As an example, in one embodiment of the present invention, the expression of the actual concentration value of the target urine detection index in the target day can be specifically, for example, as follows:

[0045] in, Indicates the actual concentration value of the target urine test indicator on the target day; represents the initial concentration value of the target urine test index on the target day; Indicates the dilution level of urine on the target day.

[0046] The true concentration value of each urine test indicator on the target day and the true concentration value of each urine test indicator on other days can be obtained by the same method as above.

[0047] Step S3: according to the change of the real concentration value of the same urine test index in each day within the preset time period, the concentration fluctuation degree of each urine test index is obtained; the concentration fluctuation degree of all urine test indexes is comprehensively analyzed to obtain the urine evaluation factor of the person to be tested.

[0048] When the urine quality of the person to be tested is good, the concentration change of the same urine test indicator on different days is not obvious and the concentration level of the same urine test indicator tends to be stable. When the urine quality of the person to be tested is poor, the concentration level of the same urine test indicator on different days is usually unstable and has large fluctuations. Therefore, the changes in the true concentration values ​​of the same urine test indicator on each day within the preset time period can be analyzed, and the obtained concentration fluctuation degree can reflect the fluctuation degree of the true concentration value of each urine test indicator on different days. Subsequently, the concentration fluctuation degrees of all urine test indicators are comprehensively evaluated to test the urine condition of the person to be tested.

[0049] Preferably, in one embodiment of the present invention, the method for obtaining the concentration fluctuation degree of each urine detection index specifically includes: First, within a preset time period, based on the difference in the actual concentration value of the target urine detection index between each day and the next adjacent day, a first concentration fluctuation parameter of the target urine detection index is obtained. The larger the first concentration fluctuation parameter, the more unstable the concentration change of the target urine detection index on each day and the larger the concentration fluctuation, thereby providing a data basis for the subsequent calculation of the concentration fluctuation degree of the target urine detection index.

[0050] Preferably, in one embodiment of the present invention, the method for obtaining the first concentration fluctuation parameter of the target urine detection index specifically includes: The absolute value of the difference between the actual concentration value of the target urine detection index between each day and the next adjacent day is taken as the concentration change of the target urine detection index every day. The larger the concentration change, the greater the difference in the concentration of the target urine detection index of each day relative to the next day, which means that the concentration of the target urine detection index has fluctuated significantly. Therefore, the average value of the concentration change of the target urine detection index on all days within the preset time period can be used as the first concentration fluctuation parameter of the target urine detection index.

[0051] It should be noted that there is no next day adjacent to the last day. In this case, the average value of the concentration change of the target urine detection index in all days before the last day can be used as the concentration change of the target urine detection index in the last day.

[0052] Then, the absolute value of the difference between the actual concentration value of the target urine detection index and the standard concentration value of the target urine detection index every day is used as the concentration deviation value of the target urine detection index every day. The larger the concentration deviation value, the more the actual concentration value of the target urine detection index deviates from the standard concentration value, and the more obvious the concentration fluctuation of the target urine detection index in each day. Then, the average value of the concentration deviation values ​​of the target urine detection index in all days within the preset time period is used as the second concentration fluctuation parameter of the target urine detection index. The larger the second concentration fluctuation parameter, the more unstable the concentration change of the target urine detection index on each day and the larger the concentration fluctuation, thereby providing a data basis for the subsequent calculation of the concentration fluctuation degree of the target urine detection index.

[0053] Among them, the standard concentration value of the urine detection index is a known value. The standard concentration values ​​of different urine detection indexes are different. Under normal circumstances, the concentration of the urine detection index is usually stable near the standard concentration value.

[0054] Then, the first concentration fluctuation parameter and the second concentration fluctuation parameter are integrated and normalized, and the calculation result is limited to , thereby obtaining the concentration fluctuation degree of the target urine detection index.

[0055] In the embodiment of the present invention, the integration of the first concentration fluctuation parameter and the second concentration fluctuation parameter may be achieved by calculating the sum or product of the two parameters, which is not limited herein.

[0056] As an example, in one embodiment of the present invention, the expression of the concentration fluctuation degree of the target urine detection index can be specifically, for example, as follows:

[0057] in, Indicates the concentration fluctuation degree of the target urine test index; Indicates The concentration change of the target urine test index during the day; A first concentration fluctuation parameter representing a target urine detection index; Indicates the number of days in a preset time period; Indicates The actual concentration value of the target urine test indicator in the day; Indicates the standard concentration value of the target urine test indicator; Indicates The concentration deviation value of the target urine test index in the day; A second concentration fluctuation parameter representing a target urine detection index; Represents the normalization function.

[0058] The concentration fluctuation degree of each urine test indicator can be obtained by the same method as above. The concentration fluctuation degree of each urine test indicator can reflect the urine condition of the person to be tested. Then, all urine test indicators can be combined to conduct a comprehensive analysis of the concentration fluctuation degree of all urine test indicators to obtain the urine evaluation factor of the person to be tested. Subsequently, the urine condition of the person to be tested can be accurately evaluated based on the urine evaluation factor.

[0059] Preferably, in one embodiment of the present invention, the average value of the concentration fluctuation degree of all urine detection indicators is used as the urine evaluation factor of the person to be tested.

[0060] As an example, in one embodiment of the present invention, the expression of the urine evaluation factor of the person to be tested can be specifically, for example, as follows:

[0061] in, represents the urine assessment factor of the person to be tested; Indicates The concentration fluctuation degree of each urine test indicator; Indicates the number of urine test indicators.

[0062] At this point, the urine evaluation factor of the person to be tested is obtained.

[0063] Step S4: Based on the urine evaluation factor, the urine condition of the person to be tested is evaluated.

[0064] The larger the urine evaluation factor is, the more unstable the concentration changes of the urine test indicators of the person being tested are, which further indicates that the urine condition and quality of the person being tested are poor. Therefore, based on the urine evaluation factor, the urine condition of the person being tested can be accurately evaluated to improve the accuracy of urine testing of the person being tested.

[0065] Preferably, in one embodiment of the present invention, the method for evaluating the urine condition of a person to be tested specifically includes: If the urine evaluation factor is less than the preset evaluation threshold, the urine quality of the person to be tested is good, otherwise, the urine quality of the person to be tested is poor.
