Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urine LH concentration monitoring, and particularly relates to an ovulation intelligent detection system and method. BACKGROUND

[0002] Fertility problems have always been one of the focuses of social attention. The popularization and development of reproductive health services such as ovulation monitoring can help reduce the incidence of reproductive health problems such as infertility and improve fertility. Through ovulation monitoring, women can accurately predict their ovulation time, thereby improving the chances of conception. For couples who want to have a baby, it is crucial to understand the ovulation of women.

[0003] Current ovulation monitoring mainly includes basal body temperature monitoring, cervical mucus monitoring, ovulation test paper monitoring, B-ultrasound monitoring, and endocrine hormone monitoring. The above commonly used ovulation monitoring technologies have many problems and cannot conveniently and accurately help women who want to get pregnant to detect ovulation. The main defects and deficiencies of the prior art are as follows:

[0004] 1. Basal body temperature monitoring: refers to the body temperature when getting up in the morning without activity. It is always low in the pre-ovulation period, and increases by about 0.2-0.5℃ after ovulation, and continues until the onset of menstruation. The basal body temperature is monitored to infer the ovulation. This method has low accuracy and is affected by factors such as cold, insomnia, alcohol consumption, and taking certain drugs.

[0005] 2. Cervical mucus monitoring: the cervical mucus becomes thin, transparent, and easy to pull before ovulation, and the amount of mucus secretion increases. The ovulation is monitored by observing the cervical mucus. This method requires certain professional knowledge and experience to judge, and is highly subjective.

[0006] 3. Ovulation test paper monitoring: the ovulation time is predicted by detecting the level of luteinizing hormone (LH) in urine. LH reaches a peak before ovulation, and the test paper shows strong positive at this time. This method cannot quantitatively determine the LH concentration by observing and comparing the color change of the test paper strip, and the accuracy is limited.

[0007] 4. B-ultrasound monitoring: the development of ovary and follicle is directly observed by clinical B-ultrasound examination, including the size, shape, and number of follicles, to judge the ovulation. This method is time-consuming, needs to frequently go back and forth to the hospital, and is relatively expensive, which is not conducive to long-term detection.

[0008] 5. Endocrine hormone monitoring: the endocrine hormone levels such as estrogen, progesterone, and luteinizing hormone are checked by blood sampling, to indirectly judge the ovulation. This method needs to go to the hospital for blood sampling, and needs to be monitored multiple times, which has poor operability. SUMMARY

[0009] The application aims to provide an ovulation intelligent detection system and method, which combines the intelligent semi-quantitative immune chromatography test paper urine LH concentration monitoring with the clinical examination for ovulation detection, and avoids the subjective error of human judgment.

[0046] Figure 1This invention discloses an intelligent ovulation detection system, comprising: an immunoassay strip image acquisition device, which acquires an image of an immunoassay strip containing urine to be tested by photographing the immunoassay strip of a patient; a test strip LH concentration value calculation device, which receives and processes the image of the immunoassay strip containing urine to be tested sent by a communication device to obtain the patient's test strip LH concentration value; an LH concentration value storage device, which stores the patient's test strip LH concentration values ​​calculated by the test strip LH concentration value calculation device based on the received images of the immunoassay strip containing urine to be tested over multiple consecutive days; an ovulation prediction device, which predicts that ovulation is about to occur based on the trend of the patient's test strip LH concentration values ​​over multiple consecutive days and the time when the test strip LH concentration value approaches its peak; and an ovulation confirmation device, which prompts the patient to undergo a sex hormone test and an ultrasound examination when the ovulation prediction device predicts that ovulation is about to occur, and then uses the results of the patient's sex hormone test and ultrasound examination to finally confirm that ovulation is about to occur.

[0047] Figure 2 This invention discloses an intelligent ovulation detection method, comprising: an immunoassay strip image acquisition module that photographs an immunoassay strip containing urine to be tested, acquiring an image of the immunoassay strip; a test strip LH concentration value calculation module that receives and processes the image of the immunoassay strip containing urine to be tested to obtain the patient's test strip LH concentration value; an LH concentration value storage device that stores the patient's test strip LH concentration values ​​calculated by the test strip LH concentration value calculation device based on the received images of the immunoassay strip containing urine to be tested over multiple consecutive days; an ovulation prediction module that predicts the patient's imminent ovulation based on the trend of the patient's test strip LH concentration values ​​over multiple consecutive days, identifying the time when the test strip LH concentration value approaches its peak; and an ovulation confirmation device that prompts the patient to undergo sex hormone testing and ultrasound examination when the ovulation prediction device predicts the patient's imminent ovulation, and then uses the results of the patient's sex hormone testing and ultrasound examination to finally confirm that ovulation is imminent.

[0048] In a preferred embodiment of the present invention, the image acquisition device for the immune layer test strip is the camera device of a mobile phone; the LH concentration value calculation module, the LH concentration value storage device, the ovulation prediction module, and the ovulation determination module are all located in the mobile phone.

[0049] This invention determines the concentration by comparing the RGB differences between the C and T lines and the middle area on the test strip image.

[0050] like Figure 3 As shown, the positioning method for the C-line and T-line of the reagent strip is as follows:

[0051] The test strip results display area is divided into upper and lower regions. Perform the following operations on the two regions respectively to obtain the positions of the C and T lines;

[0052] convert the segmented image into RGB three-channel data;

[0053] calculate the average value of the G channel of each row of the segmented image; (because the white area of the reagent strip and the red result display area are most different in the G channel)

[0054] calculate the average value of the G channel of the middle 10% of the original image; (because the middle part is closest to white and has no color; the selection of 10% avoids large calculation and ensures that the obtained average value is highly accurate)

[0055] find the row position with the largest difference from the average value of the middle part G channel, which is the C line or T line position.

[0056] The test paper LH concentration value calculation device of the application determines the LH concentration value of the test paper by comparing the RGB difference values of the C, T line and the middle area on the immunolayer test paper picture of the urine to be detected. The RGB difference value diff is calculated as follows:

[0057]

[0058] wherein R, G and B respectively correspond to the RGB difference values of the middle white area and the positions corresponding to the C and T lines, and rmean is the average value of the middle white area and the positions corresponding to the C and T lines in the R channel.

[0059] Determining the LH concentration value of the test paper includes: judging whether the color difference value is greater than the preset color threshold value; if not, it is determined that the color concentration difference is not obvious from the original color concentration, and it is judged as no result display; if yes, it is determined that the color concentration difference is obvious from the original color concentration, it is judged as having result display, and the color difference at the position is compared with the color difference in the standard library to confirm the concentration of the test paper.

[0060] The preset color threshold value: after shooting multiple reagent strips of different concentrations and calculating the concentrations 0 and 10 (the lowest concentration obtained by blending) by the above method, the most values can be distinguished as much as possible.

[0061] The color difference in the standard library: multiple reagent strips of different concentrations are shot, the color difference values corresponding to the C and T lines of different concentrations are calculated by the above method, and the standard values of the color difference corresponding to different concentrations are determined by regression. For example, concentration 10 corresponds to x1, concentration 15 corresponds to x2, etc.

[0062] The ovulation detection principle of the application is to predict the ovulation time by detecting the luteinizing hormone (LH) level in urine. Luteinizing hormone reaches a peak before ovulation, and the occurrence of this peak usually indicates that ovulation is about to occur. The specific operation includes:

[0063] Selecting Test Time: Start testing at a specific phase of the menstrual cycle, generally recommended to start 5-7 days before ovulation, and test at a fixed time every day to capture the changes in LH levels more accurately.

[0064] Collecting Urine: Collect the urine sample using a dry, clean container. Note that the first morning urine should not be used as LH levels at this time can be unstable due to various factors. It is recommended to collect urine between 10 am and 8 pm.

[0065] Removing Test Paper: Tear open the aluminum foil packet and remove the semi-quantitative ovulation test paper.

[0066] Immersion in Urine: Dip the absorbent end of the test paper (usually the end indicated by the arrow) vertically into the urine, keeping it for a certain period (such as 20 seconds or 30 seconds), the specific time according to the test paper instructions. Note not to let the urine level exceed the maximum line on the test paper.

[0067] Removing Test Paper: After removing the test paper from the urine, place it flat on a dry, clean surface.

[0068] Waiting for Reaction: Wait for the reaction according to the time required on the test paper instructions, generally 5-10 minutes or more.

[0069] Observing Color Strip: Observe the color strip in the middle section of the test paper. The color intensity of the color strip reflects the concentration of LH in the urine.

[0070] Comparing Color Card: Compare the color strip on the test paper with the color card attached to the test paper, find the color block closest to the color of the color strip, and record the corresponding numerical value.

[0071] Recording Numerical Value: After each test, record the numerical value on the test paper. As the LH level rises, the numerical value will also increase accordingly.

[0072] Observing Trend: After several consecutive days of testing, observe the trend of the numerical value. When the numerical value starts to rise significantly, it means that the LH level is approaching the peak.

[0073] Estimating Ovulation Time: When the numerical value reaches or approaches the peak value (such as 65), it means that ovulation is about to occur. At this time, you can increase the testing frequency (such as testing every 4 hours) to capture the ovulation time more accurately. When the numerical value starts to decline from the peak value (such as from 65 to 45), it means that ovulation has occurred or is about to end.

[0074] Maintaining Consistency in Testing: Try to test at the same time every day and use the same urine collection method.

[0075] Avoiding Interference Factors: Avoid activities that may affect LH levels such as excessive water intake or strenuous exercise before testing.

[0076] The ovulation detection reagent of the present application can predict the ovulation time, but is not 100% accurate. Therefore, other methods (such as sex hormone detection, B-ultrasound examination, etc.) can be combined to improve accuracy.

[0077] The execution steps of identifying the rule between the ovulation time and the self-detected LH concentration value:

[0078] 1. Since the LH peak usually appears 1-2 days before ovulation, ovulation will occur within 24-36 hours after the peak. By using ovulation test paper through intelligent recognition algorithm, the LH concentration in urine is detected. When the ovulation test paper detects a sharp rise in LH concentration, forming an "LH peak", it indicates that ovulation is about to occur.

[0079] 2. At this time, the ovulation monitor person immediately goes to the hospital for sex hormone examination and B-ultrasound examination. When the sex hormone detection result shows a sharp rise in estrogen level, and the LH test paper also shows strong positive, it can further confirm that ovulation is about to occur. At the same time, check the prog value, the normal value during the ovulation period is usually between 0.2-0.6 ng / ml, and after ovulation, it is 6.5-32.2 ng / ml.

[0080] 3. Through color ultrasound examination, the development of follicle can be directly observed. Before ovulation, the follicle will gradually increase and mature. At the time of ovulation, the follicle will rupture and release the ovum, at this time, the ultrasound examination can see the disappearance or collapse of the follicle.

[0081] 4. The doctor combines the self-detected LH concentration value, sex hormone detection result, and ultrasound examination result: through comprehensive analysis of the LH concentration value detected by the ovulation test paper, the sex hormone detection result, and the color ultrasound examination result, the ovulation time can be accurately judged. When the LH test paper shows strong positive reaction, the sex hormone detection shows a sharp rise in estrogen level, and the ultrasound examination shows mature follicle, it can be confirmed that ovulation is about to occur.

[0082] Record the self-detected LH concentration value at this time, this LH concentration is the concentration when the ovulation monitor person is about to ovulate. In the future, when the LH concentration is detected again, it means that ovulation is about to occur.

[0083] For example, when a certain girl named Xiaoli who is preparing for pregnancy, performs ovulation self-detection, when the self-detected LH concentration is 60, which is close to the peak concentration, after consulting the doctor, she goes to the hospital for sex hormone detection and ultrasound examination. After examination, it is found that the sex hormone detection shows a sharp rise in estrogen level and the ultrasound examination shows mature follicle, record the concentration 60 at this time, which is the concentration when Xiaoli is about to ovulate, when the next LH concentration reaches 60 again, it means that the ovulation time is coming.

[0084] The use method of the present application is as follows: the patient uses the mobile phone terminal "pregnancy hope" WeChat mini program integrated with the self-developed immune chromatography test paper urine LH concentration automatic detection algorithm, uses the mobile phone to take a photo of the immune layer test paper with the to-be-detected urine, and then uploads the photographed picture to the "pregnancy hope" mini program, at this time the mini program will automatically calculate the LH concentration value of the test paper and record it in the system. The doctor of the assisted reproduction department estimates the ovulation time in combination with the LH concentration values detected for the patient multiple times. At the same time, the patient is subjected to intravenous blood sex hormone detection and color ultrasound examination, and the ovulation time and the rule between the LH concentration value automatically identified by the mini program, the sex hormone detection result and the color ultrasound examination result are identified. After discovering the ovulation rule, the patient can realize self-detection of the LH concentration of the immune chromatography test paper through the "pregnancy hope" mini program, accurately judge the ovulation time, and provide support for successful pregnancy.

[0085] The intelligent semi-quantitative immune chromatography test paper urine LH concentration monitoring and clinical examination combined ovulation detection clinical application mode proposed by the present medical technology is an effective, convenient and accurate ovulation monitoring method, which can help the women to be pregnant to discover the ovulation rule and determine the ovulation time in time.

[0086] Through the WeChat mini program, the intelligent immune chromatography test paper urine LH concentration detection technology, and the blood examination and color ultrasound of the medical institution, the patient can conveniently and accurately perform ovulation detection at home, reasonably determine the ovulation date, and avoid the problems of large subjective factor influence caused by single use of immune chromatography test paper, inaccuracy, high time and economic cost of frequent detection in the medical institution, and unsustainability.

[0087] The present application uses the WeChat mini program to automatically identify the LH concentration value by taking a photo of the immune chromatography test paper, and compared with the traditional artificial basic body temperature monitoring, cervical mucus monitoring and ovulation test paper monitoring, the subjectivity error of artificial judgment is avoided, the operation is more convenient, and the use of quantitative LH value is more objective.

[0088] The present application uses the WeChat mini program to automatically identify the LH concentration value by taking a photo of the immune chromatography test paper, and compared with the traditional artificial basic body temperature monitoring, cervical mucus monitoring and ovulation test paper monitoring, the subjectivity error of artificial judgment is avoided, the operation is more convenient, and the use of quantitative LH value is more objective.
