It is attached to the back sheet 11b together with the material 22. An adhesive 26 is applied to the covering sheet 27 on the inner surface of the skin facing surface side. The covering sheet 27 is used to remove these adhesives from the vent opening 25 formed at the portion where the printing base material 22 is removed and the outer peripheral portion of the printing base material 22, and the back surface of the urine removing pad 11. The urine sensor 20 is attached to the sheet 11b so that the urine sensor 20 is sandwiched between the sheet 11b and the back sheet 11b.

As the back sheet 11b, the top sheet 11a, and the absorbent body 11c of the urine collecting pad 11, those conventionally used for absorbent articles such as disposable diapers, the urine collecting pad 11, and sanitary napkins can be used without particular limitation. As the back sheet 11b, for example, a liquid-impervious insulating sheet (such as a moisture-permeable resin film) used for absorbent articles, or a nonwoven fabric (for example, an air-through nonwoven fabric or a spunbond) produced by various manufacturing methods is used for the insulating sheet. A laminated sheet obtained by laminating a nonwoven fabric, a spunlace nonwoven fabric, a needle punch nonwoven fabric, or the like can be used. As the topsheet 11a, for example, a hydrophilic and liquid-permeable nonwoven fabric or a three-dimensional aperture film can be used.

  Furthermore, in the present embodiment, the adhesive 26 can adopt a known application pattern such as a spiral shape, a summit shape, an omega shape, a curtain shape, or a stripe shape as the application pattern in which the non-application portion 26a exists. However, from the viewpoint of maintaining air permeability on the sheet to which the urination sensor 20 is attached, the application pattern in which the non-application part 26a is present in the lacking part of the printing base material 22 is preferable, and is a spiral shape. Is more preferable.

Based on the time when the urinary leakage from the absorbent article 10 is confirmed, for example, input by a caregiver, the hitting suggestion unit 80 identifies the time zone in which the absorbent article 10 causing the urine leakage is worn. In addition, based on the data stored in the urination data storage unit 50 and the inclination data storage unit 60, absorption is performed in the time period from the posture of the wearer during urination determined in the time period determination unit 70. The place where the urine leakage has occurred is estimated from the absorbent article 10 and advice is given on how to apply the absorbent article so that the urine leakage does not occur from the estimated place. It is preferable that the data collection unit 30, that is, the acceleration sensor 34 is attached to the ventral side because the positional relationship between the main body absorbent body 12 c and the acceleration sensor 34 in the absorbent article 10 can be easily kept constant.

  Moreover, in this embodiment, the application method proposal part 80 estimates the presence or absence of the shift | offset | difference of the absorbent article 10 in the said time slot | zone from the inclination data in the said time slot | zone preferably memorize | stored in the inclination data storage part 60, The method of applying the absorbent article 10 is advised, including a proposal when it is estimated that a deviation has occurred.

  Further, in the present embodiment, the absorbent article application method suggesting apparatus 1 preferably stores advice items relating to the application of the absorbent article 10 corresponding to the place where the estimated urine leakage occurred from the absorbent article 10. The absorptive article 10 includes an advice item storage unit 85 that selects the advice item stored in the advice item storage unit 85 so that urine leakage does not occur from the estimated location. Advise how to apply.

The urination data storage unit 50 that constitutes the absorbent article application proposing device 1 according to the present embodiment is measured by the urine sensor 20 attached to the absorbent article 10, and impedance due to urine wetting and spreading in the absorbent article 10. The wearer's urination data based on the change is acquired together with the urination time data by the wetness data acquisition unit 51 and stored in the database 90. The urination data storage unit 50 identifies the time when the change in impedance is equal to or greater than a specific value as the wet state when the absorbent article 10 is wet with urine. That is, the wetness data acquisition unit 51 determines whether or not the absorbent article 10 is wet based on the amount of change in impedance, and specifies the time point when it is determined that there is wetness as the wet time.
The urination data storage unit 50 of the present embodiment includes a wetting detection unit 54 that determines whether or not wetting is present, a wetting time calculation unit 52 that specifies a wetting time, and a urine absorption amount absorbed by the urine collecting pad 11 at the wetting time. And a urine absorption amount calculation unit 53 to be calculated (see FIG. 7). Hereinafter, the data on the presence / absence of wetting, the time of wetting at which wetting has occurred, and the amount of urine absorption are collectively referred to as wetting data.
The wetting detection unit 54 detects the presence or absence of wetting from a change in impedance. Specifically, the wetness detection unit 54 determines whether the measured impedance change amount is due to wetness due to urination or noise. Whether wetting due to urination or noise is determined by whether or not the impedance change amount is equal to or greater than a specific value. As the noise, for example, there is an impedance change caused by an event other than urination such as sweat. When it is determined that urination has occurred, the wetting detection unit 54 supplies the impedance change amount determined to have urinated to the wetting time calculation unit 52 and the urine absorption amount calculation unit 53 as urination data of the wearer.
The wetting time calculation unit 52 stores the time when the impedance change amount determined to be wet is measured as the wetting time, and stores the wetting time as urination time data in the wetting time accumulation table 92 in the database 90.
The urine absorption amount calculation unit 53 calculates the urine absorption amount at each wetting time from the impedance change amount measured by the urination sensor 20. The amount of urine absorbed is the amount of urine absorbed by the absorbent article per urination, which is obtained by calculating the amount of change in impedance. The urine absorption amount calculation unit 53 calculates the urine absorption amount using the impedance change amount at the time of wetting, and the urine absorption amount as a result of the calculation is stored in the urine absorption amount accumulation table 93 in the database 90 as wearer urination data. Remember.
The urine absorption amount calculation unit 53 detects the wearer's posture with an acceleration sensor and estimates the distribution of urine in the urine collection pad 11 in order to increase the calculation accuracy when estimating the urine output. The urination amount calculation in the urine absorption amount calculation unit 53 is preferably performed in consideration of selecting a calculation formula suitable for the estimated distribution or multiplying the coefficient according to the estimated distribution.

  The urination data storage unit 50 may not include the urine absorption amount calculation unit 53 that calculates the urine absorption amount at each wet time as the urine data of the wearer, but in order to effectively prevent urine leakage, the absorbent article From the viewpoint of grasping the wet pattern, the urination data storage unit 50 preferably includes a urine absorption amount calculation unit 53.

  As shown in FIG. 7, the database 90 stores a wetting time accumulation table 92 that stores a wetting time (urination time data) that is a calculation result of the wetting time calculation unit 52 for each wearer, which is stored by the urination data storage unit 50. And a urine absorption amount accumulation table 93 for storing the urine absorption amount (urination data), which is the calculation result of the urine absorption amount calculation unit 53, for each wearer. The urine absorption amount accumulation table 93 is configured so that the urine absorption amount is reset to zero when the urine collecting pad 11, that is, the absorbent article 10 is replaced. Specifically, in the urine absorption amount accumulation table 93, when the data collection unit 30 is removed from the terminal portions 24a and 24b of the urination sensor 20 having an electrode group, the voltage application between the electrodes by the impedance change detection circuit 31b is cut off. And the accumulated data of the urine absorption amount, that is, the urine absorption amount and the total urine absorption amount are reset to zero. Of the information in the wetting time accumulation table 92 and the urine absorption amount accumulation table 93, the wetting time and urine absorption amount are stored in the wetting information table 95 in the database 90 before being reset to zero. That is, the wetness information table 95 stores information on the amount of urine absorbed for each wet time.

  The inclination data storage unit 60 configuring the absorbent article application proposing device 1 according to the present embodiment acquires inclination data measured by the acceleration sensor 34 of the data collection unit 30 attached to the absorbent article 10 as inclination data. It is acquired together with time data by the unit 61 and stored in the database 90. The inclination data storage unit 60 is sent from the information processing device 400 that forms the data acquisition unit 41, and is measured by the acceleration sensor 34 of the data collection unit 30 attached to the urination sensor 20, and the absorbent article 10 and the urine collection pad. 11, tilt data in the X-axis direction, Y-axis direction, and Z-axis direction are acquired by the tilt data acquisition unit 61 together with the respective time data by the timer 33, and stored in the tilt data accumulation table 94 in the database 90. It is stored as tilt data of the data collection unit 30.

  Thus, in the posture determination unit 70 and the hitting suggestion unit 80 described later, the urination time data stored in the urination data storage unit 50 and the time data stored in the inclination data storage unit 60 are collated, so that X From the inclination data in the axial direction, the Y-axis direction, and the Z-axis direction, the posture of the wearer, the wearing state of the absorbent article 10 and the urine collecting pad 11 and the positional deviation at a predetermined urination time and time zone can be determined.

  The posture determination unit 70 configuring the absorbent article application proposing device 1 according to the present embodiment determines the posture of the wearer during urination from the data stored in the urination data storage unit 50 and the inclination data storage unit 60. To do. The posture determination unit 70 is based on inclination data obtained by the acceleration sensor 34 of the data collection unit 30 attached to the absorbent article 10, and an attachment state determination unit 71 that determines an attachment state related to the inclination and displacement of the absorbent article 10. And an information output unit 72 that outputs information on the wearing state at a predetermined urination time and time zone.

The wearing state determination unit 71 determines the wearing state of the absorbent article 10 from the inclination data of the acceleration sensor measured by the acceleration sensor 34 of the data collection unit 30. The wearing state of the absorbent article 10 means the inclination and displacement of the absorbent article 10 (urine collection pad 11) to which the acceleration sensor 34 is attached.
The wearing state determination unit 71 specifies the inclination of the acceleration sensor 34 based on the output values of the XYZ axes of the acceleration sensor 34, thereby specifying the inclination of the absorbent article 10 to which the acceleration sensor 34 is attached. To do. For example, as shown in FIGS. 8A to 8C, the acceleration sensor 34 has an X axis in the waist width direction on the abdomen side of the wearer wearing the absorbent article 10, a Y axis in the height direction, and a front-rear direction. The Z-axis is arranged along each. The inclination of each axial direction of the XYZ axes indicates the inclination of the absorbent article 10, but as one factor that affects the inclination of the absorbent article 10, the posture of the wearer wearing the absorbent article 10 Impact. For example, when the absorbent article 10 is worn in a straight direction with respect to the body direction, the inclination of each axis of the XYZ axes is a sitting posture (see FIG. 8A) and a supine posture (FIG. 8 ( b)] and the posture (see FIG. 8C) facing sideways (left) on the back. The state in which the absorbent article 10 is worn in a straight direction with respect to the body direction is a state in which the absorbent article 10 is worn with the wearer's front-rear direction and the longitudinal direction of the absorbent article 10 matched. Say. On the other hand, even when the posture when the absorbent article 10 is worn is the same, for example, depending on how the absorbent article 10 is applied, the direction of the absorbent article 10 is inclined diagonally to the left and right with respect to the body direction. May be worn in the state. In this case, the inclination of each axial direction of the XYZ axes varies depending on the direction in which the absorbent article 10 is worn (how to apply the absorbent article 10). The wearing state determination unit 71 identifies the inclination of the acceleration sensor 34 based on the output values of the acceleration sensor 34 in the XYZ axes. That is, the inclination data of the acceleration sensor 34 is an output value of the inclination of each axis direction of the XYZ axes.
The method in which the wearing state determination unit 71 specifies the inclination of the absorbent article 10 using the acceleration sensor 34 of the data collection unit 30 is not limited to the method illustrated in FIGS. The method can be used.

The wearing state determination unit 71 of the posture determination unit 70 determines the inclination of the absorbent article 10 in consideration of the influence of the posture when the absorbent article 10 is worn. Specifically, the relationship between the inclination of the acceleration sensor 34, that is, the output values of the three axes of the XYZ axes by the acceleration sensor 34, and the posture of the wearer when the absorbent article 10 is worn straight with respect to the body orientation The inclination of the absorbent article 10 is determined according to the mounting state determination table shown in Table 1 and the mounting state determination flow shown in FIG. In Table 1 and FIG. 9, the “upper side” of the inclination of the absorbent article 10 means that the ventral region A of the back sheet 11 b is positioned on the “up” side in the vertical direction and the urine collecting pad 11. The state in which the urine collecting pad 11 is placed so that the longitudinal direction is substantially horizontal (lateral) to the direction orthogonal to the vertical direction. “Upward oblique” means that the ventral region A of the back sheet 11b is positioned on the “upper” side in the vertical direction, and the longitudinal direction of the urine collecting pad 11 is along the height direction with respect to the vertical direction. This indicates a state where the urine collecting pad 11 is placed so that the head side of the Y-axis is raised and tilted. Further, “downwardly inclined” means that the ventral region A of the back sheet 11b is positioned on the “upper” side in the vertical direction, and the longitudinal direction of the urine collecting pad 11 is along the height direction with respect to the vertical direction. This indicates a state where the urine collecting pad 11 is placed such that the head side of the Y axis is tilted downward. Further, “lower side” is approximately the direction in which the ventral region A of the back sheet 11b is positioned on the “lower” side in the vertical direction and the longitudinal direction of the urine collecting pad 11 is perpendicular to the vertical direction. This refers to the state in which the urine pad 11 is placed so as to be horizontal (horizontal). The inclination of the absorbent article 10 (urine collection pad 11) is further distinguished into the left direction and the right direction based on the output value of the X axis. In this embodiment, when the absorbent article 10 is worn straight with respect to the direction of the body, the inclination of the absorbent article 10 is “upward”, “upward” is sitting, “lower” is sitting on the knee. There is a tendency that the inclination of the absorbent article 10 corresponds to each posture, such as bending, “bottom side” lying down.
For example, when the absorbent article 10 is worn straight with respect to the body direction and the inclination (output value) of the acceleration sensor 34 is 170 on the X axis, 170 on the Y axis, and 125 on the Z axis, absorption is performed. The inclination of the absorbent article 10 (the urine collecting pad 11) is “upside”, and when the absorbent article 10 has such an inclination, the wearer wears the absorbent article in a generally upright posture. That is, the wearing state determination unit 71 according to the present embodiment wears the “upper side” as “the wearer is facing up” based on the output values where the X axis is 170, the Y axis is 170, and the Z axis is 125. It is determined that the inclination of the absorbent article is “upside”.

  About the determination of the inclination of the absorbent article 10 performed by the mounting state determination unit 71 of the posture determination unit 70, when the absorbent article 10 is worn straight against the body direction using the mounting state determination flow shown in FIG. Explain the case. For example, the output value of the Z-axis is compared with the wearing state determination table of Table 1, and when it is 218 or more, the inclination of the absorbent article 10 and “lower horizontal” are determined. In this case, the wearer's posture tends to be prone. When the output value of the inclination Z axis of the absorbent article 10 is 217 or less, the output value of the Y axis is compared with the wearing state determination table of Table 1, and when the output value is 160 or less, the inclination of the absorbent article 10 Is compared with the wearing state determination table shown in Table 1. As a result, when the X-axis output value is 150 or less, it is determined as “upward oblique right”, and when the X-axis output value is 180 or more, it is determined as “upward oblique left”. If the output value of the X axis is neither 150 or less nor 180 or more, it is determined as “upward”. In this embodiment, when the inclination of the absorbent article 10 is “upward and rightward”, the posture of the wearer tends to sit sideways and rightward. Moreover, when the inclination of the absorbent article 10 is “upward and leftward”, the posture of the wearer tends to sit sideways and to the left.

  Further, when the output value of the Z axis is 217 or less, the output value of the Y axis is compared with the wearing state determination table of Table 1, and when the output value is 181 or more, the inclination of the absorbent article 10 is set to “down slant”. And the output value of the X axis is compared with the mounting state determination table of Table 1. As a result, when the X-axis output value is 150 or less, the inclination of the absorbent article 10 is determined to be “downwardly to the right”, and when the X-axis output value is 180 or more, the absorbent article The inclination of 10 is determined as “downwardly to the left”. When the output value of the X axis is not less than 150 or more than 180, it is determined that the inclination is “down oblique” when the knee is bent. In this embodiment, when the inclination of the absorbent article 10 is “down diagonally right”, the posture of the wearer tends to be knee-bending laterally and rightward. Moreover, when the inclination of the absorbent article 10 is “down diagonally left”, the posture of the wearer tends to be knee-bending laterally and to the left.

Further, when the output value of the Z axis is 217 or less, the output value of the Y axis is compared with the wearing state determination table of Table 1, and when it is neither 160 or less nor 181 or more, the inclination of the absorbent article 10 Is determined as “upper horizontal”, and the output value of the X-axis is compared with the mounting state determination table of Table 1. As a result, when the output value of the X axis is 150 or less, the inclination of the tilt-absorbing article 10 in the posture in the horizontal direction on the back and in the right direction is determined as “upward horizontal rightward”. When the output value of the X-axis is 180 or more, the inclination of the tilt-absorbing article 10 in the posture in the supine sideways and leftward direction is determined as “upper horizontal leftward”. When the output value of the X axis is not 150 or less or 180 or more, it is determined that the inclination is “upside” in the posture of the supine front. In this embodiment, when the inclination of the absorbent article 10 is “upward to the right”, the posture of the wearer tends to be sideways on the back and rightward. Moreover, when the inclination of the absorbent article 10 is “upward / leftward”, the posture of the wearer tends to be sideways on the back and leftward.
As described above, the wearing state determination unit 71 of the posture determination unit 70 has the inclination of the absorbent article 10 as “lower horizontal”, “upper horizontal”, “upper horizontal”, “upper diagonal”, “upper horizontal”, It can be determined whether it is “downwardly inclined” or “downwardly inclined horizontally”. “Horizontal” in each posture, such as “upward horizontal direction” or “upward horizontal direction” means rightward or leftward. In the present embodiment, the wearing state determination unit 71 determines the wearer's posture as one factor that affects the inclination of the absorbent article 10, but depending on how the diaper pad is applied, etc. Since the absorbent article 10 is not always worn straight against the body orientation, the actual absorption is also considered in consideration of the influence of the orientation of the absorbent article 10 on the body orientation at the time of wearing. The inclination of the property article 10 can be accurately determined.

The wearing state determination unit 71 of the posture determination unit 70 can determine the displacement of the absorbent article 10 in addition to the inclination of the absorbent article 10. The displacement of the absorbent article 10 is, for example, from the position where the crotch region C of the absorbent article 10 (urine collecting pad 11) is attached so as to contact the excretion part (inseam part) of the wearer. Means a state shifted in the front-rear direction (longitudinal direction Y) or the left-right direction (width direction X) or a state shifted in the thickness direction of the absorbent article 10. The positional shift of the absorbent article 10 is caused by the movement of the absorbent article 10 in a worn state. When the movement K of the absorbent article 10 obtained by the following equation (1) is 2 or more, the absorbent article 10 It is determined that a positional shift has occurred. That is, the wearing state determination unit 71 determines whether or not the absorbent article 10 is misaligned based on the movement K of the absorbent article 10 when the acceleration sensor 34 is measured.
N in the following formula (1) is the number of data of each output value (slope data) in three directions of the XYZ axes measured at a predetermined time interval. Specifically, the motion K of the absorbent article 10 is obtained from the following formula (1) based on 60 data of the output values in the three directions. In this embodiment, the output values in the three directions of the XYZ axes are measured 60 times in 10 minutes. That is, in the present embodiment, the output values in the three directions are measured once every 10 seconds. The measurement time interval can be set arbitrarily, and the number of measurements n can also be set arbitrarily.

  Data relating to the tilt of the absorbent article 10 and the presence or absence of misalignment is stored in the wetting information table 95 of the database 90. More specifically, these data are supplied to the wetting information table 95 from the wearing state determination unit 71 and stored in the wetting information table 95. The above wetting time (urination time data) and urine absorption amount (urination data) And stored in the wetness information table 95. Hereinafter, the information regarding the wetting time and the presence / absence of the inclination and displacement of the absorbent article 10 at that time are also referred to as the information on the wearing state at the time of wetting.

The information output unit 72 of the posture determination unit 70 outputs information on the wearing state of the absorbent article 10 during urination. The absorbent article application proposing device 1 of the present embodiment is stored in the wetness information table 95 in the display unit 101 of the information processing apparatus 100 by the information output unit 72 and the absorbent article 10 during urination during urination. Outputs information about the wearing state of the. As shown in FIG. 10, the display unit 101 shows a time zone corresponding to the wetting time, and information related to the inclination and displacement of the absorbent article 10. Specifically, the time schedule when the absorbent article 10 according to this embodiment is worn for 24 hours is shown, and the time zone corresponding to the wet time, that is, the column of the time zone when the wet product is wet is colored. In addition, information on the inclination and displacement of the absorbent article 10 is also shown (see FIG. 10). In FIG. 10, the inclination of the absorbent article is shown as “diaper inclination”. For example, regarding the urine absorption amount, the column of 12:00 pm to 12:15 pm is darker than the column of 11:45 am to 12:00 pm. This indicates that there was wetness, that is, there was urination between 11:45 am and 12:15 pm. Moreover, it is shown that the inclination of the absorbent article 10 in the time zone from 11:45 am to 12:15 pm was an “upward slant” inclination. Further, it is shown that the inclination of the absorbent article 10 has changed from “down diagonal” to “up horizontal” from the time of 3:45 am, and the absorbent article 10 has been displaced. . That is, it can be seen that the position shift occurred with the change in the inclination of the absorbent article 10 due to the wearer turning over at 3:45 am. Moreover, when urine leak is discovered after 3:45 am, it is anticipated that the change in the inclination or displacement of the absorbent article 10 at 3:45 am is the cause of urine leak.
Thereby, when the urine leakage is found in the absorbent article 10 worn by the care recipient, the caregiver in the application proposal unit 80 to be described later, from the wearing state at the time of wetting before the time when the urine leakage was discovered, It is possible to grasp a wearing state that may cause urine leakage. Moreover, caregivers and the like determine how to apply the absorbent article 10 according to the proposal by the application proposal unit 80 based on the state of installation of the absorbent article 10 when such urine leakage is discovered. It is possible to take measures to prevent urine leakage such as adjustment.

In this embodiment, the urination data storage unit 50 includes a urine absorption amount calculation unit 53, and the urine absorption amount calculation unit 53 calculates the urine absorption amount measured at the time of each urination from the impedance. As shown in FIG. 10, the information output unit 72 of the posture determination unit 70 outputs information on the urine absorption amount calculated by the urine absorption amount calculation unit 53 together with information on the wearing state when wet due to urination. In the urine absorption amount information of the present embodiment, as shown in FIG. 10, the color shade in the column of the time zone corresponding to the wetting time is changed according to the urine absorption amount. By outputting information on the amount of urine absorbed together with information on the wearing state when wet due to urination, caregivers and the like can use absorbent articles with an absorption capacity corresponding to the amount of urine absorbed, and urine leakage Can be effectively prevented. The absorbent article having an absorption capacity corresponding to the urine absorption capacity means an absorbent article having an absorption capacity larger than the urine absorption capacity. For example, in the time schedule shown in FIG. 10, when no urine leak is found at 9 am and 11 am and urine leak is found at 1 pm, the time zone from 9 am to 1 pm is absorbable in FIG. 10. It is shown that there is no change in the inclination or misalignment of the article 10. Therefore, it is suggested that the urine leakage discovered at 1 pm is not due to a change in the inclination or displacement of the absorbent article. This suggests that an absorbent article having an absorption capacity larger than the amount of urine absorbed in the time zone from 9 am to 1 pm is used as a measure for preventing urine leakage. As described above, it is preferable that the information output unit 64 outputs the urine absorption amount information together with the wearing state information when wet.
The data information of the wetting pattern shown in FIG. 10 represents the urine absorption amount every 15 minutes by the shade of the color corresponding to that amount. That is, the darker the color, the greater the amount of urine absorption, and the lighter the color, the less urine absorption. In FIG. 10, the greater the number of urinations, the greater the amount of urination discharged into the absorbent article 10, so the color indicating the amount of urine absorption increases with the number of urinations. Further, when the absorbent article is replaced, the urine absorption amount becomes 0, and the urine absorption amount column corresponding to the replacement time of the absorbent article becomes colorless (white). The urine absorption amount column starts with a light color and becomes a dark color with the urine absorption amount. The amount of urine absorption may be expressed stepwise by letters, symbols, etc. corresponding to the amount. In addition, the display of wetness when there is wetness may be only the time when there was wetness.
