A high-precision ovulation time prediction method and device

Abstract

The invention provides a high-precision ovulation time prediction method and device. According to the scheme of predicting the ovulation time through the change trend of absorption amount measured for several times adjacently, the occurrence of an ovulation event is determined through the conversion from the calculation of the absorption amount to the sudden drop, the error caused in the process of converting the absorption amount into LH concentration is reduced, and the prediction precision of the scheme can be accurate to hours.

Description

technical field [0001] The invention relates to the field of ovulation detection, in particular to a high-precision ovulation time prediction method and device. Background technique [0002] After the follicles in a woman's body mature, the egg cells will be released from the ovaries. This process is called ovulation. The date of female ovulation is usually about 14 days before the next menstruation, this day is called the ovulation day. Five days before the ovulation day, four days after that, and the day of the ovulation day, this stage is called the ovulation period. Accurately knowing the ovulation day can help women obtain fertility or birth control control. [0003] At present, the ovulation time is known mainly through observing leucorrhea, recording basal body temperature, ovulation test strip detection and B-ultrasound monitoring. Among them, ovulation test strip detection is the most convenient way. This method requires continuous testing for multiple days. The c...

Problems solved by technology

[0005] 1. Due to the limitation of the test paper production process, there is inconsistency (intra-batch difference) in the same batch of test paper. Urine with the same luteinizing hormone concentration will appear inconsistent in thickness and color depth after reacting on different test paper, resulting in absorption There are certain changes

[0006] 2. Due to the large difference between different devices, even the same test paper with the same luteinizing hormone (LH) concentration has a large difference in the absorption of different devices.

[0007] 3: Due to the large difference between different batches of test paper (difference between batches), the ovulation detection equipment must be bound to a batch of test paper. When changing to other batches of test paper, the absorption of the test paper at the same luteinizing hormone (LH) concentration The amount of luteinizing hormone (LH) may vary greatly, resulting in a large deviation in the concentration of luteinizing hormone (LH) calculated by the ovulation detection equipment, resulting in inaccurate inference of ovulation time.

[0008] The prior art CN108333377A provides a way to calculate the ovulation time by measuring the increase value of LH concentration per unit time and calculating the time when LH reaches the peak value according to the size of the LH peak value. However, this method still needs to convert the collected value into the test value into LH concentration will inevitably introduce errors in the conversion process, thus affecting the detection results

Moreover, this method tests the LH increase value per unit time, and calculates the time to reach the LH peak value through the increase value. This calculation is inaccurate, and the obtained ovulation time and the actual error are relatively large.
