Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, in order to detect the amount of menstrual blood attached to a sanitary product by detecting the difference in weight before and after use of the sanitary product using a storage box for used sanitary products having a weight detection unit, for example, when the storage box is installed at home, when replacing the sanitary product at a place where the storage box is not installed, weight measurement cannot be performed, so the amount of menstrual blood cannot be obtained. In addition, regarding menstrual blood that leaks from the sanitary product and adheres to clothing such as underwear, or menstrual blood that is directly discharged into the toilet when replacing the sanitary product in the toilet, weight measurement is not performed, so the amount of menstrual blood leakage or the amount of menstrual blood discharged into the toilet cannot be obtained. Although the total amount of menstrual blood during the menstrual period is defined by a society or the like as one of the evaluation indicators for normal menstruation, there is a problem that if there is menstrual blood that cannot be obtained as described above, the total amount of menstrual blood may be underestimated.

[0005] An object of the present invention is to appropriately obtain the total amount of menstrual blood by estimating the amount of menstrual blood that could not be obtained when away from home, menstrual blood leakage, or discharge into the toilet, etc., in order to solve the above problems.

Means for Solving the Problem

[0006] The information processing apparatus according to the present invention acquires weight data from a weight measurement unit that measures the weight of a used sanitary product, and acquires the menstrual blood volume attached to the sanitary product based on the weight data and the weight of the used sanitary product before use, a first acquisition unit; a second acquisition unit that acquires exchange information regarding replacement of the sanitary product based on an input by a user; a first calculation unit that calculates an estimated value of the menstrual blood volume not acquired by the first acquisition unit based on at least one of the menstrual blood volume acquired by the first acquisition unit and the exchange information; a second calculation unit that integrates the menstrual blood volume acquired by the first acquisition unit and the estimated value to calculate the total menstrual blood volume during the menstrual period; and a notification unit that notifies at least one of the menstrual blood volume acquired by the first acquisition unit, the estimated value, and the total menstrual blood volume.

Advantages of the Invention

[0007] According to the information processing apparatus of the present invention, based on at least one of the menstrual blood volume acquired by the first acquisition unit and the exchange information acquired by the second acquisition unit, an estimated value of the menstrual blood volume not acquired by the first acquisition unit is calculated when away from home or the like, and the menstrual blood volume and the estimated value are integrated to calculate the total menstrual blood volume. Thereby, the total menstrual blood volume can be appropriately obtained, and the user can notice their own menstruation and evaluate normal menstruation in a form that more conforms to the actual situation.

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that all of the embodiments described below show preferred specific examples of the present disclosure. Therefore, numerical values, shapes, materials, components, arrangements of components, connection forms, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, components not described in the independent claims are described as optional components.

[0010] In addition, the accompanying drawings and the following description are provided so that those skilled in the art can fully understand the present disclosure, and are not intended to limit the subject matter described in the claims thereby.

[0011] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Also, in each figure, the same reference numerals are given to substantially the same configurations, and redundant descriptions may be omitted or simplified.

[0012] In addition, in the following description, menstrual blood refers to the bloody secretions discharged from the vagina during menstruation, and includes blood and secretions other than blood (such as disintegrated endometrial tissue, vaginal fluid, cervical mucus, etc.) as components.

[0013] (Embodiment 1) Using FIG. 1, an example of the menstrual blood volume detection system according to Embodiment 1 (hereinafter referred to as this menstrual blood volume detection system) will be described. FIG. 1 is a diagram showing an example of this menstrual blood volume detection system, and FIG. 2 is a block diagram of this menstrual blood volume detection system. As shown in FIGS. 1 and 2, this menstrual blood volume detection system includes a weight measurement unit 100 that measures the weight of a sanitary box for discarding used sanitary products, an information processing device 200, and a terminal device 300 used by a user.

[0014] The information processing device 200 performs various arithmetic processes and is realized by, for example, a server, a cloud system, or the like. Further, the information processing device 200 communicates with the weight measurement unit 100 and the terminal device 300 via a network N such as a wireless communication network or a wired communication network. The terminal device 300 is realized by a smart device such as a portable personal computer, a smartphone, a tablet, or the like, and can communicate with the information processing device 200 via the network N. The terminal device 300 has functions as, for example, an input unit that receives various input commands from the information processing device 200 and causes the user to input, and a notification unit that outputs various information stored in the information processing device 200 to the terminal device 300 and notifies the user of various information.

[0015] The weight measurement unit 100 includes a sanitary box 101 for discarding used sanitary products and a weight sensor 102 that measures the weight of the sanitary box 101, and is installed in a toilet or the like in the user's home. The sanitary box 101 is placed on the weight sensor 102, and the sanitary box 101 and the weight sensor 102 are detachable, but the sanitary box 101 and the weight sensor 102 may be integrally formed. Further, a garbage bag may be installed in the sanitary box 101, and used napkins may be discarded in the garbage bag. When the used napkins in the sanitary box 101 are full, the used napkins together with the garbage bag may be taken out of the sanitary box 101 and discarded as household garbage or the like.

[0016] ​The information processing device 200 includes a communication unit 210, a control unit 220, and a storage unit 230. The control unit 220 includes a first acquisition unit 221 that acquires the amount of menstrual blood adhering to the used sanitary product based on the weight data measured by the weight measurement unit 100, a second acquisition unit 222 that acquires exchange information regarding the replacement of the sanitary product, a first calculation unit 223 that calculates an estimated value of the amount of menstrual blood not acquired by the first acquisition unit 221 based on the amount of menstrual blood and the exchange information, and a second calculation unit 224 that integrates the amount of menstrual blood and the estimated value to calculate the total amount of menstrual blood.

[0017] The storage unit 230 includes a weight database 231 that stores the weight data of the sanitary box measured by the weight measurement unit 100, an exchange information database 232 that stores the exchange information acquired by the second acquisition unit 222, and a sanitary product database 233 in which the product names of the sanitary products marketed by each manufacturer of the sanitary products and the weights of the corresponding sanitary products are recorded. Further, the storage unit 230 includes an estimation database 234 that stores data, arithmetic expressions, etc. used when the first calculation unit 223 calculates the estimated value of the amount of menstrual blood, and an amount-of-menstrual-blood database 235 that stores the amount of menstrual blood acquired by the first acquisition unit 221, the estimated value of the amount of menstrual blood calculated by the first calculation unit 223, and the total amount of menstrual blood calculated by the second calculation unit 224, etc.

[0018] The sanitary product is, for example, a sanitary napkin, tampon, incontinence sheet, menstrual cup, absorbent underwear, etc. for menstruation. Hereinafter, the description will be made assuming a sanitary napkin for menstruation.

[0019] Fig. 3 shows an example of the information stored in the hygiene product database 233. As shown in Fig. 3, the hygiene product database 233 stores the specifications of the hygiene products commercially available from each napkin manufacturer. As an example of the specifications, for manufacturer C, the product name of the napkin, the corresponding classification of the napkin (daytime use, nighttime use), the presence or absence of wings, the length in the long direction when the napkin is unfolded, the weight of the napkin body before use, the weight of the individual wrap (including the release paper) wrapping the body, the combined weight of the napkin body and the individual wrap before use, the maximum absorption amount of the napkin for absorbing menstrual blood, the water retention amount, etc. These specifications can be obtained, for example, by the administrator of the information processing device 200 or the like from the specifications of the napkins publicly disclosed by each napkin manufacturer, or by actual measurement of the dimensions and weights of the napkins. As an example of the actual measurement of the absorption amount, a liquid such as water, an aqueous sodium chloride solution, or artificial blood is absorbed from the absorption surface of the napkin to be measured, and the weight change of the napkin until the liquid leaks from the napkin is measured as the maximum absorption amount. Further, after measuring the maximum absorption amount, a predetermined load is applied to the entire napkin, the weight of the napkin after the liquid leaks from the napkin is measured, and the difference between the measured value and the weight of the napkin before liquid absorption is obtained as the water retention amount. The load applied at this time may be set based on the measured value of the average load applied to the napkin when the napkin is actually worn on the body.

[0020] In addition, the person in charge of each napkin manufacturer or the like, or the user U, may be able to access the hygiene product database 233 to input and store the specifications. Further, when the specifications are changed or there is a napkin not stored in the hygiene product database 233, it may be possible to access the hygiene product database 233 to correct the specifications of the napkin or add and store the product name and specifications.

[0021] An example of the operation of the menstrual blood detection system according to the above configuration will be described with reference to Fig. 1. Note that this operation is performed by executing a menstrual blood detection program pre-installed in the information processing device 200 and a predetermined application software (hereinafter referred to as application software AP) as a terminal program installed in the terminal device 300 and the terminal program installed in the terminal device 300.

[0022] The application software AP is a computer program for at least executing a transmission process of causing the user U to input exchange information from the terminal device 300 and transmitting the input exchange information to the information processing device 200, and an output process of outputting at least one of the menstrual blood volume, estimated value, and total menstrual blood volume calculated by the information processing device 200 from the information processing device 200 to the terminal device 300.

[0023] The application software AP is prepared in the information processing device 200 or a server constituting the information processing device 200 so as to be distributable to the terminal device 300. Then, for example, when the user U obtains the weight measurement unit 100 as a product in order to use the present menstrual blood volume detection system, based on the procedure described in the instruction manual of the present menstrual blood volume detection system attached to the product, etc., the user U downloads the application software AP from the information processing device 200 or the server constituting the information processing device 200 to the terminal device 300 and performs an operation of installing the application software AP on the terminal device 300. The user U executes the application software AP installed on the terminal device 300 to use the present menstrual blood volume detection system.

[0024] During the menstrual period of the user U, the user U performs napkin replacement at home or outside. As shown in FIG. 1, when performing napkin replacement at home, the user U discards the used napkin in the sanitary box 101 (step S1). The weight sensor 102 measures the weight of the sanitary box 101 at a preset time, for example, at 0 minutes every hour, and transmits the measured weight data to the information processing device 200, and the information processing device 200 stores the weight data in the storage unit 230 (step S2).

[0025] When the preset time before the user U goes to bed arrives every day, the information processing device 200 sends a command to the terminal device 300 to acquire exchange information regarding napkin replacement (step S3). The terminal device 300 notifies the user U to input the exchange information (step S4). The user U inputs the exchange information regarding napkin replacement at home or outside to the terminal device 300 (step S5). The input exchange information is transmitted from the terminal device 300 to the information processing device 200 and stored in the storage unit 230 (step S6).

[0026] In the information processing device 200, based on the weight data stored in the storage unit 230, the exchange information, and the weight of the napkin before use previously stored in the storage unit 230, etc., the amount of menstrual blood adhering to the used napkin replaced at home (hereinafter referred to as the home-measured menstrual blood amount) is acquired by the first acquisition unit 221. The estimated value of the amount of menstrual blood that was not acquired by the first acquisition unit 221, that is, the estimated value of the amount of menstrual blood adhering to the used napkin replaced outside (hereinafter referred to as the outside-estimated value), the estimated value of the amount of menstrual blood adhering to underwear, etc. due to menstrual blood leakage (hereinafter referred to as the menstrual blood leakage estimated value), and the estimated value of the amount of menstrual blood directly discharged into the toilet during napkin replacement in the toilet (hereinafter referred to as the toilet discharge estimated value) are calculated by the first calculation unit 223. Also, the integrated value of the home-measured menstrual blood amount, the outside-estimated value, the menstrual blood leakage estimated value, and the toilet discharge estimated value is calculated by the second calculation unit 224. Further, this integrated value is calculated daily by the second calculation unit 224, and the total value during the menstrual period of the integrated value calculated daily is calculated as the total menstrual blood amount. The home-measured menstrual blood amount, the outside-estimated value, the menstrual blood leakage estimated value, the toilet discharge estimated value calculated by the first calculation unit 223, and the daily integrated value and the total menstrual blood amount calculated by the second calculation unit 224 are stored as menstrual blood amount information (step S7).

[0027] When the user U requests to view the menstrual blood amount information from the terminal device 300 (step S8), the terminal device 300 refers to the menstrual blood amount information stored in the information processing device 200 (step S9) and presents the menstrual blood amount information from the terminal device 300 to the user U (step S10).

[0028] The menstrual blood volume information SH shown in FIG. 1 is an example of menstrual blood volume information, and graphs of the daily menstrual blood volume during this menstrual period (self-measured menstrual blood volume at home, estimated value when away from home, estimated value of menstrual blood leakage, estimated value of toilet discharge, integrated value), trend graphs of the total menstrual blood volume from the past, etc. are presented. The range of 20 g to 140 g in the trend graph of the total menstrual blood volume indicates the normal range of the total menstrual blood volume defined by academic societies, etc., and it is possible to grasp whether the total menstrual blood volume is within the normal range.

[0029] Next, the details of the above operation will be described. FIG. 4 shows a graph F1 representing the change in the weight W of the sanitary box 101 measured by the weight sensor 102 associated with the wearing and replacement of the napkin at home and away from home on the first day of the menstrual start of the user U, and an example of the information F2 used when the information processing device 200 performs processes such as acquisition, calculation, and storage. In FIG. 4, the upper graph F1 shows the change in the weight W measured by the weight sensor 102, where the horizontal axis is time and the vertical axis is the weight W. The weight W is measured at 0 minutes every hour as described above. Here, if the measured values of W from time 0:00 to 24:00 are respectively W0, W1, ···, W24, then W0 to W24 are plotted as black dots on the graph.

[0030] In column a of F2, the napkin wearing and replacement timings T1 to T6 at home and away from home, and the product names C1 to C5 of the napkin bodies worn by the user at T1 to T6 are shown.

[0031] In column b of F2, the replacement information input and acquired in step S5 of FIG. 1 corresponding to T2 to T6 is shown.

[0032] In column c of F2, the variables calculated when the first acquisition unit 221 acquires the menstrual blood volume XA are shown corresponding to T2 to T6.

[0033] In column d of F2, the estimated value XB when away from home, the estimated value XC of menstrual blood leakage, and the estimated value XD of toilet discharge calculated by the first calculation unit 223 are shown corresponding to T2 to T6.

[0034] In column e of F2, the integrated values QA to QD of XA to XD for the day and the total QE of QA to QD are shown.

[0035] Describe the operation of the user U wearing and replacing the napkin on the day. As shown in column a of F1 and F2, the user U wears a napkin with the product name C1 of Company C as the first napkin at around 5 o'clock (T1) at home. After that, at around 8 o'clock (T2), it is replaced with a napkin with the product name C2, goes out at 9 o'clock, is replaced with a napkin with the product name C3 at around 12 o'clock (T3), is replaced with a napkin with the product name C3 at around 15 o'clock (T4), returns home at 18 o'clock, and is replaced with a napkin with the product name C4 at around 18 o'clock (T5) at home, and is replaced with a napkin with the product name C5 at around 21 o'clock (T6).

[0036] When wearing the napkin with the product name C1 at around 5 o'clock (T1), peel off the individual wrap that wraps the napkin body of the product name C1, discard only the individual wrap in the sanitary box 101, arrange the napkin body on the shorts, etc., and wear it on the body. After that, W6 measured by the weight sensor 102 is a value obtained by adding the weight of the individual wrap of the product name C1 to W5.

[0037] Next, in the napkin replacement at around 8 o'clock (T2), in order to wear the napkin with the product name C2 of Company C, peel off the used napkin body of the product name C1 from the shorts, etc., roll it up, peel off the individual wrap that wraps the napkin body of the product name C2, wrap the rolled-up used napkin body (product name C1) with the individual wrap, and discard it in the sanitary box 101. The napkin body of the product name C2 is arranged on the shorts, etc., and worn on the body. After that, W9 measured by the weight sensor 102 is a value obtained by adding the weight of the individual wrap of the product name C2, the weight of the napkin body before use of the product name C1 and the weight of the menstrual blood attached to the napkin body to W8.

[0038] When changing the napkin around 12:00 (T3) while away from home, since the napkin with product name C3 of Company C is to be worn, the used napkin body with product name C2 is peeled off from the shorts etc., rolled up, the individual wrap that wraps the napkin body with product name C3 is peeled off, the rolled-up used napkin body (product name C2) is wrapped with the individual wrap, and discarded in a sanitary box etc. in the toilet etc. at the place where one is away from home. The napkin body with product name C3 is arranged on the shorts etc. and worn on the body. Since one is away from home, the weight measurement by the weight sensor 102 is not performed.

[0039] When changing the napkin around 15:00 (T4) while away from home, since the napkin with product name C3 of Company C is to be worn, the used napkin body with product name C3 is peeled off from the shorts etc., rolled up, the individual wrap that wraps the napkin body with product name C3 is peeled off, the rolled-up used napkin body (product name C3) is wrapped with the individual wrap, and discarded in a sanitary box etc. in the toilet etc. at the place where one is away from home. The napkin body with product name C3 is arranged on the shorts etc. and worn on the body. Since one is away from home, the weight measurement by the weight sensor 102 is not performed.

[0040] When changing the napkin around 18:00 (T5) at home after returning, since the napkin with product name C4 of Company C is to be worn, the used napkin body with product name C3 is peeled off from the shorts etc., rolled up, the individual wrap that wraps the napkin body with product name C4 is peeled off, the rolled-up used napkin body (product name C3) is wrapped with the individual wrap, and discarded in the sanitary box 101. The napkin body with product name C4 is arranged on the shorts etc. and worn on the body. After this, W19 measured by the weight sensor 102 is the value obtained by adding the weight of the individual wrap with product name C4, the weight of the napkin body before use with product name C3, and the weight of the menstrual blood attached to the napkin body to W18.

[0041] When changing the napkin at around 21:00 (T6), since the napkin with the product name C5 of Company C is to be installed, the used napkin body with the product name C4 is peeled off from the underwear etc., rolled up, and then the individual wrap that wraps the napkin body with the product name C5 is peeled off. The rolled-up used napkin body (product name C4) is wrapped with the individual wrap and discarded in the sanitary box 101. The napkin body with the product name C5 is arranged on the underwear etc. and worn on the body. After this, W22 measured by the weight sensor 102 becomes a value obtained by adding the weight of the individual wrap of the product name C5, the weight of the napkin body before use of the product name C4, and the weight of the menstrual blood attached to the napkin body to W21.

[0042] The above is the operation of wearing and changing the napkin by the user U on the first day of the start of menstruation. However, from the second day of menstruation until the end of menstruation, although the weight measured by the weight sensor 102 and the napkin wearing and changing timing differ daily, the same operation as above is performed during napkin replacement. Note that at the last napkin replacement on the last day of menstruation, since there is no individual wrap for the napkin to be replaced next, the used napkin body that has been rolled up may be wrapped with toilet paper etc. and discarded. When discarding it in the sanitary box 101 at home, the value measured after replacement becomes a value obtained by adding the weight of the wrapped toilet paper, the weight of the napkin body before use, and the weight of the menstrual blood attached to the napkin body to the previous weight measurement value.

[0043] Next, with reference to FIG. 5, the operations of obtaining the menstrual blood volume and calculating the estimated value will be described. FIG. 5 is an operation flowchart showing an example of the operation of the information processing device 200.

[0044] The user U installs the weight measurement unit 100 in the toilet at home, connects the weight measurement unit 100 and the home WIFI router etc. by pairing etc., and after establishing communication with the information processing device 200 via the network N, at every 0 minutes, the weight sensor 102 measures the weight W of the sanitary box 101 and transmits the measured weight W and the measurement time to the information processing device 200 (step S101). The transmitted data is received by the communication unit 210 via the network N and stored in the weight database 231 (step S102).

[0045] The operations of S101 to S102 are repeated until the end of the day (24:00) (step S103). Note that since it is generally difficult to predict the menstrual start time in many cases, the operations of S101 to S102 are performed regardless of whether the user U is in the menstrual period or not. Also, regarding the menstrual start time, it may be the time when the menstrual start is input from the menu of the application software AP of the terminal device 300. However, as shown in the graph F1 of FIG. 4, when the user U wears the first napkin C1 at around 5 o'clock (T1) due to the start of menstruation, T1 may be regarded as the menstrual start time by detecting the change in weight W caused by discarding the individual wrap into the sanitary box 101. In this case, the threshold value for detecting the change in weight W may be set so as to distinguish noise such as vibration at the installation location of the weighing unit 100 from the individual wrap. For example, it may be set to a value of 0.1 g or more and less than 0.5 g.

[0046] Note that in order to notify that the sanitary box 101 is full of used napkins, a full notification threshold value WM is set. When the weight W becomes WM or more, a full notification signal is transmitted from the information processing device 200 to the terminal device 300, and the terminal device 300 notifies the user U that the sanitary box 101 is full. Based on the notification from the terminal device 300, the user U takes out the used napkins in the sanitary box 101 and discards them as household waste or the like.

[0047] Next, in parallel with the operations of the above steps S101 to S103, after the menstrual start time, every day, when it reaches the time preset by the user U from the terminal device 300, such as the time before going to bed, the second acquisition unit 222 transmits a command to the terminal device 300 to acquire exchange information regarding napkin replacement, and the terminal device 300 notifies the user U to input the exchange information (step S201). The user U inputs the exchange information regarding napkin replacement at home or outside to the terminal device 300 (step S202).

[0048] As shown in column b of information F2 in FIG. 4, the exchange information to be input includes the individual wrap of the napkin to be discarded at home or outside, the product name of the napkin body, the apparent ratio RB of the area of menstrual blood adhesion to the napkin absorption surface of the used napkin discarded outside, the apparent area ratio RC of the amount of menstrual blood leaked onto underwear or the like and the amount of menstrual blood adhered to the used napkin when changing the napkin at home or outside, and the apparent and sensory ratio RD of the amount of menstrual blood discharged into the toilet and the amount of menstrual blood adhered to the used napkin when changing the napkin at home or outside. The input exchange information is transmitted from the terminal device 300 to the information processing device 200 and stored in the exchange information database 232 (step S203).

[0049] When the day ends in step S103, the first acquisition unit 221 calculates the time difference D of the weight W stored in the weight database 231. For example, the difference D0 at the 0 o'clock hour is the difference between W1 and W0, the difference D1 at the 1 o'clock hour is the difference between W2 and W1, and so on, and the differences D0 to D23 are calculated. Then, those differences that are equal to or greater than a preset threshold TH are extracted. The threshold TH at this time may be set so as to distinguish between the individual wrap and the napkin body. For example, it may be set to a value of 0.5 g or more and 3 g or less. As shown in graph F1 of FIG. 4, among D0 to D23, D8, D18, and D21 are equal to or greater than the threshold TH, and D8, D18, and D21 are stored in the weight database 231 (step S104).

[0050] In addition, after the weight WA is measured at a certain measurement time TM, the user U may discard the used napkin in the sanitary box 101 outside the sanitary box 101 to empty the sanitary box 101 due to the used napkin in the sanitary box 101 being full or the like. At this time, the time difference D between the weight WB measured at the next measurement time TN and WA becomes a negative value. When the time difference D becomes a negative value, in the first acquisition unit 221 The weight WC of the sanitary box 101 in a state where nothing is stored inside is stored in advance in the weight database 231, and the difference DG between WB and WC is further calculated. If DG is equal to or greater than the threshold value TH, it is assumed that a napkin exchange has occurred between the times TM and TN, and the used napkin has been discarded inside the sanitary box 101, and the difference DG is stored in the weight database 231.

[0051] Also, a measurement button for manually measuring the weight may be provided on the weight sensor 102, and when the user U presses the measurement button, the weight measurement is performed, and the weight data and the time at that time are stored in the weight database 231. For example, after the weight WA is measured at a certain measurement time TM, a used napkin is discarded inside the sanitary box 101 until the next measurement time, and then, before the next measurement time, the used napkin inside the sanitary box 101 becomes full, etc., and the user U may discard the used napkin inside the sanitary box 101 outside the sanitary box 101 to empty the inside of the sanitary box 101. In this case, by pressing the measurement button by the user U before emptying the inside of the sanitary box 101, the weight before emptying the inside of the sanitary box 101 can be measured, and thus the weight change due to the added used napkin can be obtained.

[0052] Next, the first acquisition unit 221 collates the product names of the individual wraps and the napkin bodies of the napkins discarded at home among the exchange information stored in step S203 with the specifications of the napkins stored in the sanitary product database 233, and extracts the weights of the individual wraps of the napkins discarded at home and the napkin bodies before use. For example, at T2 in FIG. 4, the individual wrap of product name C2 and the napkin body of product name C1 are discarded, but in the sanitary product database 233 of FIG. 3, the weight of the individual wrap of product name C2 is extracted as C25, and the weight of the napkin body before use of product name C1 is extracted as C14. Similarly, at T5, the weight of the individual wrap of product name C4 is extracted as C45, the weight of the napkin body before use of product name C3 is extracted as C34, and at T6, the weight of the individual wrap of product name C5 is extracted as C55, and the weight of the napkin body before use of product name C4 is extracted as C44 (step S105).

[0053] Then, the first acquisition unit 221 subtracts the weight of the napkin before use extracted in S105 from the difference D stored in step S104 to obtain the menstrual blood volume XA. For example, the menstrual blood volume XA2 attached to the used napkin at T2 in FIG. 4 is obtained by subtracting C25 and C14 from D8. Similarly, at T5, the menstrual blood volume XA5 is obtained by subtracting C45 and C34 from D18, and at T6, the menstrual blood volume XA6 is obtained by subtracting C55 and C44 from D21 (step S106).

[0054] Next, the first calculation unit 223 calculates the estimated value XB of the destination outside, the estimated value XC of menstrual blood leakage, and the estimated value XD of toilet discharge (step S107). These calculations are performed based on the estimation formulas stored in the estimation database 234. FIG. 5 shows an example of the information stored in the estimation database 234. The estimation database 234 has a sub-database 2341 which is information for calculating XB, a sub-database 2342 which is information for calculating XC, and a sub-database 2343 which is information for calculating XD.

[0055] As shown in FIG. 5, the sub-database 2341 has an estimation formula for obtaining the estimated value XB of the destination outside by multiplying the ratio RB of the menstrual blood adhesion area to the napkin absorption surface and the absorption amount YB of the napkin. According to this estimation formula, for example, at T3 in FIG. 4, since the menstrual blood adhesion ratio RB at the destination outside is RB3 as the replacement information in column B and the product name of the discarded napkin is C2, the absorption amount YB of the napkin with the product name C2 in the sanitary product database 233 in FIG. 3 is C27, so the estimated value XB3 of the destination outside at T3 is obtained by multiplying RB3 and C27. Similarly, the estimated value XB4 of the destination outside at T4 is obtained by multiplying RB4 and C37.

[0056] As shown in FIG. 5, the sub-database 2342 has an estimation formula for obtaining the menstrual blood leakage estimated value XC by multiplying the visual area ratio RC of the menstrual blood leaked onto the underwear or the like and the menstrual blood adhering to the used napkin by the amount of menstrual blood YC adhering to the used napkin. According to this estimation formula, for example, at T2 in FIG. 4, the menstrual blood leakage ratio RC at home as the replacement information in column B is RC2, and the amount of menstrual blood YC adhering to the used napkin is the amount of menstrual blood XA2 at home in column C. Therefore, the menstrual blood leakage estimated value XC2 at T2 is obtained by multiplying RC2 and XA2. Similarly, the menstrual blood leakage estimated value XC3 at T3 is the product of RC3 and XB3, the menstrual blood leakage estimated value XC4 at T4 is the product of RC4 and XB4, the menstrual blood leakage estimated value XC5 at T5 is the product of RC5 and XA5, and the menstrual blood leakage estimated value XC6 at T6 is the product of RC6 and XA6.

[0057] As shown in FIG. 5, the sub-database 2343 has an estimation formula for obtaining the toilet discharge estimated value XD by multiplying the ratio RD of the visual appearance and physical sensation of the menstrual blood discharged into the toilet and the menstrual blood adhering to the used napkin by the amount of menstrual blood YD adhering to the used napkin. According to this estimation formula, for example, at T2 in FIG. 4, the toilet discharge ratio R at home as the replacement information in column B is RD2, and the amount of menstrual blood YD adhering to the used napkin is the amount of menstrual blood XA2 at home in column C. Therefore, the toilet discharge estimated value XD2 at T2 is obtained by multiplying RD2 and XA2. Similarly, the toilet discharge estimated value XD3 at T3 is the product of RD3 and XB3, the toilet discharge estimated value XD4 at T4 is the product of RD4 and XB4, the toilet discharge estimated value XD5 at T5 is the product of RD5 and XA5, and the toilet discharge estimated value XD6 at T6 is the product of RD6 and XA6.

[0058] Next, the second calculation unit 224 calculates the integrated value QA of XA for the day, the integrated value QB of XB for the day, the integrated value QC of XC for the day, and the integrated value QD of XD for the day, calculates the sum of QA to QD as QE, and stores it in the menstrual blood volume database 235 (step S108). For example, from column C in FIG. 4, QA is obtained by integrating XA2, XA5, and XA6. Also, from column D in FIG. 4, QB is obtained by integrating XB3 and XB4, QC is obtained by integrating XC2 to XC6, and QD is obtained by integrating XD2 to XD6.

[0059] The operations from step S101 to step S108 are repeated until the user U inputs the end of menstruation from the menu of the application software AP of the terminal device 300 (step S109). During this period, the second calculation unit 224 calculates the integrated value of QE calculated daily in step S108 and stores it in the menstrual blood volume database 235.

[0060] When the end of menstruation is input in step S109, the integrated value of QE calculated up to that day becomes the total menstrual blood volume in that menstruation. After that, when the user U requests to view the menstrual blood volume information from the terminal device 300 (step S110), the terminal device 300 refers to the menstrual blood volume information stored in the menstrual blood volume database 235 and presents the menstrual blood volume information to the user U from the terminal device 300 (step S111). As already described, the menstrual blood volume information SH shown in FIG. 1 is an example, and it presents a graph of the menstrual blood volume (self-measured value QA at home, estimated value QB at the destination, estimated value QC of menstrual blood leakage, estimated value QD of excretion in the toilet, QE) for each day during the current menstrual period, the total menstrual blood volume, a trend graph of the total menstrual blood volume from the past, etc.

[0061] According to the above operation, according to the present embodiment, based on the menstrual blood volume acquired by the first acquisition unit and the exchange information acquired by the second acquisition unit, for the menstrual blood volume not acquired by the first acquisition unit due to being away from home, menstrual blood leakage, excretion to the toilet, etc., their estimated values are calculated, and the menstrual blood volume and the estimated values are integrated to calculate the total menstrual blood volume. As a result, the total menstrual blood volume can be appropriately obtained, and the user can be aware of their own menstruation and evaluate normal menstruation in a form that more conforms to the actual situation.

[0062] (Embodiment 2) An example of a menstrual blood amount detection system according to the second embodiment will be described. The difference from the first embodiment is that the second acquisition unit 222 acquires at least one of the time of stay at the destination of the user U, the duration of stay, the duration of wearing a sanitary napkin, the number of times of changing a sanitary napkin, the amount of activity, and the stress level as the replacement information acquired and stores it in the replacement information database 232, and calculates an estimated value of the destination of stay based on the menstrual blood amount information at home stored in the menstrual blood amount database 235 and the replacement information stored in the replacement information database 232. The time of stay at the destination of stay, the duration of stay, and the duration of wearing a sanitary napkin can be acquired, for example, by input from the terminal device 300 of the user U. Also, for example, the user U may wear a portable activity meter on her body to acquire the amount of activity, or wear a wristwatch-type device with a heart rate measuring function to measure the fluctuation of the RR interval of the heart rate to acquire the stress level.

[0063] The operation of the above configuration will be described. First, the operations of steps S101 to S103 shown in FIG. 5 are performed as in the first embodiment. Next, in steps S201 to S203, at least one of the time of stay at the user U's destination, the duration of stay, the duration of wearing a sanitary napkin, the number of times the sanitary napkin was changed, the amount of activity, and the stress level is input as replacement information and stored in the replacement information database 232. Also, as in the first embodiment, the menstrual blood leakage ratio RC and the toilet discharge ratio RD are input and stored in the replacement information database 232. Then, the operations of steps S104 to S106 are performed as in the first embodiment.

[0064] Next, in step S107, the first arithmetic unit 223 calculates an estimated value of the destination based on the menstrual blood volume information at home stored in the menstrual blood volume database 235 and the exchange information stored in the exchange information database 232. This procedure will be described with reference to FIG. 7. FIG. 7 shows the stored information of the sub-database 2344 of the estimation database 234 according to the second embodiment. As shown in FIG. 7, the sub-database 2344 has an estimation formula for calculating an estimated value of the destination based on the exchange information stored in the exchange information database 232 and the menstrual blood volume information at home stored in the menstrual blood volume database 235.

[0065] This estimation formula is, for example, a multiple regression formula with the estimated value XE of the menstrual blood volume at the destination as the target variable and a plurality of variables YE1, YE2,... extracted from the menstrual blood volume information at home and the exchange information respectively as the explanatory variables, and includes a multiple regression formula for obtaining the estimated values XE1, XE2,... of the destination every day. Regarding the derivation of such a multiple regression formula, in a data collection experiment using a plurality of subjects in advance, every day during menstruation, the weight measurement data of the menstrual blood volume at home and at the destination, and the stay time, stay duration, napkin wearing time, napkin exchange frequency, activity level, stress level, etc. at the destination are obtained. After accumulating the number of data required for analysis, a multiple regression analysis is performed with the menstrual blood volume at the destination every day as the target variable and the menstrual blood volume information at home and the exchange information every day as the explanatory variables, and the formula can be derived.

[0066] The first arithmetic unit 223 calculates the estimated value of the destination every day based on the estimation formula of the sub-database 2344, and calculates the estimated value of menstrual blood leakage and the estimated value of toilet discharge based on the estimation formulas of the sub-database 2342 and the sub-database 2343 respectively. Then, the same operations as in the first embodiment are performed in steps S108 to S111. Note that the explanatory variables shown in the sub-database 2344 of FIG. 7 are only examples, and are not limited to these explanatory variables, and other variables related to the estimation of the menstrual blood volume at the destination may be used.

[0067] In Embodiment 1, when obtaining the estimated value of the destination of going out, it was necessary to input the product name of the napkin discarded at the destination and the ratio of the area of menstrual blood adhesion to the napkin absorption surface. However, since the ratio RB of the area of menstrual blood adhesion to the napkin absorption surface was determined by the appearance seen by the user, the estimation accuracy of the menstrual blood volume might vary depending on the subjectivity of the user. On the other hand, in the menstrual blood volume detection system of Embodiment 2, as exchange information, quantitative exchange information such as the stay time, residence time, napkin wearing time, napkin replacement frequency, activity level, and stress level at the destination of going out is used to obtain the estimated value of the destination of going out. Therefore, the estimation accuracy of the menstrual blood volume is not affected by the subjectivity of the user, and the estimation accuracy has the effect of improving.

[0068] (Modification Example 1) In addition, the multiple regression equation shown in the sub-database 2344 of FIG. 7 was obtained by collecting data using a plurality of subjects in advance, acquiring the data set of the objective variable and the explanatory variable shown in the sub-database 2344 of FIG. 7, accumulating the number of data required for analysis, and then performing multiple regression analysis with the menstrual blood volume at the destination of going out every day as the objective variable and the menstrual blood volume information and exchange information at home every day as the explanatory variables. However, the data set of the objective variable and the explanatory variable obtained from the user U of this menstrual blood volume detection system may be additionally accumulated in the above accumulated data, and the multiple regression equation may be updated by performing multiple regression analysis at an arbitrary timing, and the estimated value of the destination of going out may be obtained based on the updated multiple regression equation. Also, the data sets of other users other than the user U may be additionally accumulated, and the multiple regression equation may be updated by performing multiple regression analysis at an arbitrary timing, and the estimated value of the destination of going out may be obtained based on the updated multiple regression equation.

[0069] (Modification Example 2) Also, in Embodiment 2, the estimated value of the destination was obtained by the multiple regression equation shown in the sub-database 2344 of FIG. 7. However, by a data collection experiment using a plurality of subjects in advance, a data set of the objective variable and the explanatory variables shown in the sub-database 2344 of FIG. 7 was acquired, and after accumulating the number of data necessary for analysis, the amount of menstrual blood at the destination each day was set as the objective variable, and machine learning was performed using the amount of menstrual blood information at home each day and the exchange information shown in the sub-database 2344 of FIG. 7 as the explanatory variables, and the estimated value of the destination may be obtained by the obtained learning model. In this case, a data set of the objective variable and the explanatory variables acquired from the user U of this menstrual blood detection system may be additionally accumulated in the above accumulated data, the learning model may be updated at an arbitrary timing by machine learning, and the estimated value of the destination may be obtained based on the updated learning model. Also, data sets of other users other than the user U may be additionally accumulated, the learning model may be updated at an arbitrary timing by machine learning, and the estimated value of the destination may be obtained based on the updated learning model.

[0070] (Modification 3) Also, for example, when an article other than the used napkin is discarded in the sanitary box 101 or an article such as toilet paper is placed on the sanitary box 101, the accurate amount of menstrual blood cannot be obtained. In such a case, since the user U performs data correction, the terminal device 300 may access the weight database 231 so that the weight information stored in the weight database 231 can be rewritten.

[0071] (Modification 4) Also, in order to streamline the input of daily exchange information, for example, in advance, user U inputs from the terminal device 300 the number of days since the start of menstruation and the product names of the napkins used for each time zone of the day, and stores the product names of the napkins used for each time zone since the start of menstruation in the exchange information database 232 in advance as default information. By doing so, it is also possible to calculate the menstrual blood volume or estimated value without performing steps S201 to S203 in FIG. 5. When using a napkin that is not stored as default information, the user manually inputs the product name of the used napkin from the terminal device 300. As a result, when inputting daily exchange information, the trouble of inputting the product name of the used napkin can be saved, and the usability is improved.

[0072] (Modification Example 5) Also, based on the information stored in the exchange information database 232 and the menstrual blood volume database 235 obtained from user U or users other than user U, the control unit 220 obtains the probability distribution of the occurrence of menstrual blood leakage for each product name of the napkin and stores it in the storage unit 230. User U accesses the storage unit 230 from the terminal device 300, and the probability distribution of menstrual blood leakage for each product name can be made viewable on the terminal device 30 0. For example, FIG. 8 shows an example of a database of the probability distribution of menstrual blood leakage occurrence for each napkin product name obtained with the above configuration. The menstrual blood leakage occurrence probability database 236 is included in the storage unit 230. The graph in FIG. 8 is the probability distribution data of product name C1. The horizontal axis of the graph is the home-measured menstrual blood volume XA and the estimated value XB when away from home shown in FIG. 4, and the vertical axis is the probability PM of menstrual blood leakage occurring with a certain menstrual blood volume. PM can be obtained by extracting the menstrual blood volume (here, XA and XB are collectively referred to as the menstrual blood volume) for each product name of the used napkin body from the information stored in the exchange information database 232 and the menstrual blood volume database 235, and calculating the occurrence probability PM of cases where the menstrual blood leakage ratio RC is greater than a preset threshold value TRC for each range of the menstrual blood volume. TRC can be set arbitrarily.

[0073] As shown in FIG. 8, when the menstrual blood volume increases, the probability PM of menstrual blood leakage occurrence increases. In the above procedure, the control unit 220 acquires probability distribution data for napkins with other product names as well. The user U accesses the menstrual blood leakage occurrence probability database 236 from the terminal device 300 and views the menstrual blood leakage occurrence probability distribution data of napkins with each product name on the terminal device 300. Thus, for example, it becomes possible to select a napkin with a low probability of menstrual blood leakage according to the expected menstrual blood volume in future menstruation, improving the usability. Also, a plurality of TRCs may be set and graphs of a plurality of occurrence probabilities PM corresponding thereto may be generated. For example, a user worried about menstrual blood leakage can refer to the graph of the occurrence probability PM corresponding to a TRC of zero or a low value to select a napkin with a low probability of menstrual blood leakage, and it becomes possible to select a napkin according to the degree of concern about menstrual blood leakage.

[0074] (Modification Example 6) In addition, in Modification Example 5, further, when the user U inputs from the terminal device 300 the expected menstrual blood volume in future menstruation, based on the input menstrual blood volume, the control unit 220 refers to the menstrual blood leakage occurrence probability database 236 to extract the product names of napkins whose menstrual blood leakage occurrence probability PM is lower than a predetermined value TPM, and may notify the user U from the terminal device 300 of the extracted product names, the menstrual blood leakage occurrence probability, etc., further improving the usability when selecting a napkin. Note that TPM can be arbitrarily set by the user U from the terminal device 300.

[0075] (Modification Example 7) Also, in Modification Example 5, further, the control unit 220 extracts the menstrual blood volume at which the menstrual blood leakage occurrence probability of each napkin in the menstrual blood leakage occurrence probability database 236 becomes a predetermined value, and assuming that the extracted menstrual blood volume is the maximum absorption amount of the napkin, may change the absorption amount of the napkin with each product name in the hygiene product database 233. Thereby, since the absorption amount corresponding to the actual usage state of the napkin is stored in the hygiene product database 233, the estimated value of the place of going out calculated in Embodiment 1 becomes a value more corresponding to the actual usage state, improving the estimation accuracy.

[0076] (Modification Example 8) In addition, when inputting the menstrual blood leakage ratio RC into the terminal device 300 for the user U or users other than the user U, it is possible to input whether or not the napkin has shifted. The information processing device 200 calculates the shift occurrence probability for each product name of the napkin from the respective number of uses and the number of occurrences of shifts, and stores in the blood volume database 235 in combination with the product name of the napkin, the estimated menstrual blood leakage value XC, and the shift occurrence probability. The user U may be able to access the blood volume database 235 from the terminal device 300 and refer to the shift occurrence probability of the napkin for each product name from the terminal device 300.

[0077] As described above, the user U can access the blood volume database 235 from the terminal device 300 and check the shift occurrence probability of the napkin for each product name, so that a napkin with fewer occurrences of shifts can be selected. Also, when the user U inputs replacement information from the terminal device 300 or at an arbitrary timing, the information processing device 200 refers to the blood volume database 235 and extracts the shift occurrence probability of the input napkin. If the shift occurrence probability of the napkin is greater than a predetermined value, the terminal device 300 may notify the user U of caution information regarding prevention of napkin shift, such as checking the proper position and adhesion when wearing the napkin on the underwear, which is useful for preventing the napkin used by the user U from shifting.

[0078] (Modification Example 9) In addition, in Embodiment 1, the weight measurement unit 100 and a home WIFI router or the like were connected by WIFI, and the weight data measured by the weight measurement unit 100 was transmitted to the information processing device 200 via the WIFI router and the network N. However, for example, the weight measurement unit 100 and the terminal device 300 may be connected by wireless communication such as Bluetooth (registered trademark), and the weight data measured by the weight measurement unit 100 may be transmitted to the information processing device 200 via the terminal device 300 and the network N.
