And a back surface side member that includes at least a liquid-impermeable back sheet and is arranged on the skin surface side of the inspection member. The inspection member has a contact portion for contacting excrement that has passed through the surface side member, and a display portion that displays the health condition of the wearer by an indicator according to a target component contained in the excrement. The surface side member covers at least a part of the display portion. The front surface side member can be peeled off from the back surface side member so that the display portion can be visually recognized.

It is a top view which looked at the absorbent article which concerns on 1st Embodiment from the skin surface side. It is sectional drawing along the line AA shown in FIG. It is a top view which looked at the absorbent article which concerns on 1st Embodiment from the skin surface side. It is sectional drawing of the absorbent article which concerns on 2nd Embodiment. It is sectional drawing of the absorbent article which concerns on 3rd Embodiment.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.

The absorbent article according to one embodiment includes an inspection member for inspecting the health condition of the wearer and a liquid-permeable top sheet, and is a surface-side member arranged on the skin surface side of the inspection member. And a back surface side member that includes at least a liquid-impermeable back sheet and is arranged on the skin surface side of the inspection member. The inspection member has a contact portion for contacting excrement that has passed through the surface side member, and a display portion that displays the health condition of the wearer by an indicator according to a target component contained in the excrement. The surface side member covers at least a part of the display portion. The front surface side member can be peeled off from the back surface side member so that the display portion can be visually recognized.

According to this aspect, when the absorbent article is worn, the wearer's excrement reaches the inspection member through the surface side member, and the inspection member (display portion) has a target component contained in the excrement. The health status of the wearer is displayed accordingly. Since the front surface side member covers at least a part of the display portion, the wearer removes the absorbent article from the body and then peels the front surface side member from the back surface side member to expose the display portion. The display unit is easy to see. The wearer can confirm the health condition by visually recognizing the exposed display portion. Further, the surface side member is arranged on the skin surface side of the inspection member, and covers at least a part of the display portion for displaying the health condition of the wearer by the indicator. This makes it easier for the surface side member (top sheet) to come into direct contact with the wearer's skin, and makes it difficult for the indicator contained in the display portion to come into contact with the skin. Therefore, even if the absorbent article is provided with the inspection member, it is possible to easily suppress the deterioration of the wearer's touch and to suppress the damage to the skin caused by the indicator.

According to a preferred embodiment, the surface side member is formed with an opening that overlaps with the contact portion in the thickness direction. When the excrement reaches the contact part through the gaps such as fibers constituting the surface side member, the amount of excrement required for the inspection reaches the contact part as compared with the case where the excrement passes through the opening. It may take some time or some excrement may not reach the contact area. Therefore, by forming an opening in the surface side member that overlaps with the contact portion, the excrement reaches the contact portion immediately after passing through the opening, so that the amount of excrement required for the inspection can be easily reached quickly. The excrement required for the inspection can be reached at the contact portion in a short time, and the inspection accuracy can be improved while shortening the inspection time.

According to a preferred embodiment, the surface side member is composed of a plurality of sheets including the top sheet. The holes are formed only in a part of the plurality of sheets. Of the plurality of sheets, the remaining sheet covers the opening (and the contact portion), so that the inspection member is not exposed. As a result, it is possible to reliably prevent the inspection member from touching the wearer's skin while improving the inspection accuracy.

According to a preferred embodiment, the contact portion and the display portion are arranged at different positions. The display unit does not overlap the opening in the thickness direction. Since the display portion containing the indicator that reacts according to the target component does not overlap with the opening, the display portion does not come into direct contact with the wearer's skin, so that damage to the skin caused by the indicator can be suppressed.

According to a preferred embodiment, the surface side member includes a liquid impermeable sheet arranged on the non-skin surface side of the top sheet. The holes are formed in at least the liquid impermeable sheet. Even if the surface-side member has a liquid-impermeable sheet, excrement can pass through the liquid-impermeable sheet through the openings. As a result, the excrement can reach the inspection member, and the health condition of the wearer can be displayed on the display unit. On the other hand, the indicator contained in the inspection member may be dissolved in the excrement that has reached the inspection member. Since the liquid-impermeable sheet does not allow excrement to pass through except for opening holes, it is possible to prevent the excrement from returning to the top sheet. Therefore, damage to the wearer's skin due to the indicator contained in the excrement can be suppressed.

According to a preferred embodiment, the opening is a through hole that penetrates the surface side member. When the excrement reaches the contact part through the gaps between the fibers constituting the surface side member, until the amount of excrement required for the inspection reaches the contact part as compared with the case where the excrement passes through the opening. It may take some time or some excrement may not reach the contact area. Therefore, since the through hole is formed in the surface side member, the excrement can pass through the through hole and reach the contact portion immediately, so that the amount of excrement required for the inspection can be easily reached quickly. The excrement required for the inspection can be reached at the contact portion in a short time, and the inspection accuracy can be improved.

According to a preferred embodiment, the back surface side member includes a hydrophilic sheet having a higher hydrophilicity or fiber density than the liquid permeable sheet contained in the front surface side member. The inspection member is arranged on the hydrophilic sheet. Since the liquid permeable sheet arranged on the back surface side member has a higher hydrophilicity or fiber density than the liquid permeable sheet contained in the front surface side member, it is possible to prevent excrement from returning to the top sheet. Therefore, the influence of the indicator contained in the excrement on the wearer's skin can be suppressed.

(2) Outline of Absorbent Articles The outline of the absorbent articles according to the embodiment will be described below with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, panty liner, incontinence pad, fecal pad. The absorbent article may be an article that is attached and used inside a worn article such as underwear. The absorbent article 1 of the present embodiment is a sanitary napkin.

In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension may differ from the actual one. Therefore, the specific dimensions, etc. should be determined in consideration of the following explanation. In addition, there may be parts where the relationships and ratios of the dimensions of the drawings are different from each other.

FIG. 1 is a plan view of the absorbent article according to the first embodiment as viewed from the skin surface side. FIG. 2 is a cross-sectional view taken along the line AA shown in FIG. FIG. 3 is a plan view of the absorbent article according to the first embodiment as viewed from the skin surface side.

The "skin surface side" corresponds to the side facing the wearer's skin during wearing (during use). The "non-skin side" corresponds to the side that is turned away from the wearer's skin during wear (during use).

As shown in FIGS. 1 and 2, the absorbent article 1 has a front-rear direction L and a width direction W. The anteroposterior direction L is a direction extending from the front side (ventral side) of the wearer to the rear side (dorsal side), or a direction extending from the rear side to the front side of the wearer. The width direction W is a direction orthogonal to the front-rear direction L. The absorbent article has a thickness direction T extending to the skin side T1 and the non-skin side T2.

The absorbent article 1 has a central region S3, an anterior region S1 and a posterior region S2. The central region S3 is a region having an excretion port contact portion that contacts the wearer's excretion port (for example, vaginal opening). When the absorbent article is attached to the underwear, the central region S3 is located in the inseam of the underwear. That is, the central region is the inseam of the wearer, that is, the region located between the wearer's feet. The front side region S1 is located on the front side of the central region S3. The rear side region S2 is located on the rear side of the central region S3. The absorbent article 1 may have, for example, an anterior region S1, a posterior region S2, and a central region S3 so as to divide the absorbent article 1 into three equal parts in the front-rear direction L.

The absorbent article 1 includes an inspection member 20, a front surface side member 40, and a back surface side member 60.

The inspection member 20 is a member for inspecting the health condition of the wearer. Details of the inspection member 20 will be described later.

The surface side member 40 is a member that includes at least a liquid-permeable top sheet and is arranged on the skin surface side T1 of the inspection member 20. Therefore, the surface side member (top sheet) can be easily touched directly on the wearer's skin, and the inspection member 20 can be prevented from touching the skin. In the present embodiment, the surface side member 40 is composed of only a top sheet.

The surface side member (top sheet) 40 is made of any sheet-like material having a structure that allows liquid to permeate, such as a non-woven fabric, a woven fabric, a perforated plastic sheet, and a mesh sheet. As a material for woven fabrics and non-woven fabrics, both natural fibers and chemical fibers can be used.

The back surface side member 60 is a member that includes at least a liquid-impermeable back sheet and is arranged on the non-skin surface side T2 of the inspection member 20. In the present embodiment, the back surface side member 60 is composed of only the top sheet.

The back surface member (back sheet) 60 is a polyethylene sheet, a laminated non-woven fabric mainly made of polypropylene or the like, a breathable resin film, a spunbond, or a sheet in which a breathable resin film is bonded to a non-woven fabric such as spunlace. Can be used.

The inspection member 20 displays the health condition of the wearer by an indicator. In this embodiment, for example, an immunochromatography method or a test strip method can be used to inspect the health condition.

The immunochromatography method is performed by dropping excrement (for example, blood) onto a member (for example, a cellulose membrane) on which labeled particles containing an antibody are spread. When the target component (antigen) to be tested is contained in the excrement, the target component and the antibody cause an antigen-antibody reaction to form a complex. The formed complex moves on the membrane by capillarity. Another type of antibody (indicator) is linearly arranged at the destination of the complex. The complex binds to another type of antibody and develops color. The presence or absence of coloration (color change) indicates the health condition of the wearer. The wearer can confirm the health condition by visually determining the presence or absence of coloration.

In the test paper method, the indicator contained in the inspection member 20 reacts with the target component contained in the excrement to develop a color. The presence or absence of coloration (change in the color of the indicator) indicates the health condition of the wearer. The wearer can confirm the health condition by visually determining the coloration (change in color of the indicator) by the indicator.

The excrement includes, for example, blood, urine, stool, sweat and the like. Items indicating health status are, for example, physical condition-related (pH, iron deficiency anemia, renal function, myocardial infarction, inflammation / infectious disease, nutritional status evaluation, etc.), pregnancy-related (physiological cycle prediction, ovulation prediction, etc.), mental-related. (Depression tendency, drugs, etc.). The target components to be tested are, for example, urinary waste products (urine specific gravity), leukocytes, hydrogen ions (pH), proteins, glucose, ketones, urobilinogen, bilirubin, urinary occult blood, nitrites, steroids, peptides, aromatics. Compounds, FSH (follicle stimulating hormone), BUN (Urea nitorogen), AlB (Albumin), LPS (lipopolysaccharide), hCG (human chorionic gonadotropin), LH (yellow body stimulating hormone), U-ALB, CRP (C-reactib)・ Protein), myoglobin, CK-MB, troponin I, troponin T, hemoglobin, strep A, HBs antibody, HIV antibody, TP antibody, rotavirus, influenza virus, adenovirus, DNA, O-157, cocaine, marijuana, morphine Is given as an example.

The inspection member 20 has a contact portion 22 and a display portion 24. The contact portion 22 is a portion for contacting excrement. The display unit 24 is a portion that displays the health condition of the wearer according to the target component contained in the excrement.

For example, in the later lateral flow test, the contact portion 22 includes at least the region where the labeled particles containing the antibody are arranged. When the excrement touches the contact portion 22, the target component (antigen) contained in the excrement and the antibody cause an antigen-antibody reaction to form a complex. The display unit 24 includes at least a region in which an indicator (another type of antibody) that binds to the complex and develops color is arranged. Therefore, when the immunochromatography method is used, the contact portion 22 and the display portion 24 are arranged at different positions. On the other hand, in the test strip method, the contact portion 22 includes at least the region where the indicator is arranged. Since the indicator contained in the contact portion 22 reacts with the target component to develop a color, the contact portion 22 and the display portion 24 are arranged at the same position. Therefore, in this case, the contact portion 22 and the display portion 24 are the same.

As described above, when the test strip method is used, the contact portion 22, that is, the display portion 24 includes an indicator for displaying the health condition of the wearer. When the immunochromatography method is used, the contact portion 22 contains labeled particles and the display portion 24 contains an indicator for displaying the health condition of the wearer. When the contact portion 22 is provided only for guiding the excrement (target component) to the display portion 24, the contact portion 22 does not need to include an indicator.

The indicator is a chemical substance (inorganic substance, organic substance) that develops color by reacting with the target component or a component derived from the target component (for example, a complex).

The inspection member 20 may be a member capable of holding the indicator. The inspection member 20 can be made of any material such as paper, non-woven fabric, or woven cloth. The rigidity of the inspection member 20 may be less than or equal to the rigidity of the member used for the absorbent article 1. As a result, even if the absorbent article 1 includes the inspection member 20, it becomes easy to suppress deterioration of the wearer's touch. As shown in FIG. 1 and the like, the inspection member 30 may have a linear plate shape, for example.

As shown in FIGS. 1 and 2, the surface side member 40 covers at least a part of the display unit 24. As shown in FIGS. 1 and 2, the surface side member 40 covers all of the display unit 24. The indicator contained in the display unit 24 is less likely to come into contact with the skin, and damage to the skin caused by the indicator can be suppressed.

When the absorbent article 1 is worn, the wearer's excrement reaches the inspection member 20 through the surface side member 40, and the inspection member 20 (display unit 24) responds to the target component contained in the excrement. The health status of the wearer is displayed.

Here, since the surface side member 40 covers the display unit 24, the wearer cannot visually recognize the display unit 24 in the state of the absorbent article 1 in FIG. However, as shown in FIG. 3, the front surface side member 40 can be peeled off from the back surface side member 60 so that the display unit 24 can be visually recognized. Therefore, the wearer exposes the display portion 24 by peeling the front surface side member 40 from the back surface side member 60 after removing the absorbent article 1 from the body. Therefore, the wearer can easily see the display unit 24. The wearer can confirm the health condition of the wearer by visually recognizing the exposed display unit 24. In addition, the wearer does not need to carry the inspection member 20, and can easily check the inspection member 20 even when he / she is out, for example.

An opening 45 is formed in the surface side member 40. In the present embodiment, the opening 45 is a through hole that penetrates the surface side member 40. The opening 45 may have a first opening 451 and a second opening 452. The first opening 451 is an opening that overlaps with the contact portion 22 in the thickness direction T. Therefore, the surface side member 40 is formed with a first opening 451 that overlaps with the contact portion 22 in the thickness direction T. By passing the excrement through the first opening 451 it becomes easier to reach the contact portion 22 as compared with the case where the excrement passes through the gaps such as the fibers constituting the surface side member 40. Therefore, the excrement (target component) required for the inspection can be reached at the contact portion 22 in a short time, and the inspection accuracy can be improved while shortening the inspection time.

As shown in FIG. 2, the first opening 451 may be a through hole penetrating the surface side member 40 in the thickness direction T. As a result, even if the excrement is a fixed substance or a semi-solid substance and it is difficult to diffuse the surface side member 40, the excrement easily reaches the contact portion 22. Therefore, the excrement (target component) required for the inspection can reach the contact portion 22, and the inspection accuracy can be improved.

The display unit 24 does not have to overlap with the opening 45 in the thickness direction T. Since the display unit 24 containing the indicator does not overlap with the opening 45, the display unit 24 does not come into direct contact with the wearer's skin, so that damage to the skin caused by the indicator can be suppressed.

The second opening 452 is an opening that does not overlap with the contact portion 22 in the thickness direction T. The second opening 452 may be an opening that does not overlap with the inspection member 20. The excrement that has passed through the second opening 452 can reach the back surface side member 60, then move on the back surface side member 60, and reach the contact portion 22.

The opening 45 may be arranged at a position where it comes into contact with the wearer's excretion opening. Therefore, the opening 45 may be arranged in the central region S3. As a result, the excrement reaches the opening 45 without moving (diffusing) the surface side member 40. Therefore, it is possible to omit the movement of the excrement from the point where the excrement is excreted to the opening 45. The excrement required for the inspection can be reached at the contact portion 22 in a short time, and the inspection accuracy can be improved while shortening the inspection time.

The inspection member 20 is arranged in at least one of the front side region S1, the rear side region S2, and the central region S3. As shown in FIG. 1, the inspection member 20 may be arranged so as to straddle the rear side region S2 and the central region S3. The contact portion 22 may be located at least in the central region S3, and the display portion 24 may be located at least in the posterior region S2 (or the front region S1). As a result, since the contact portion 22 is located in the region in contact with the excretion port, the excrement can easily reach the contact portion 22. Further, by arranging the display unit 24 in the rear side area S2 (or the front side area S1), the distance from the rear end portion (or front end portion) of the absorbent article 1 in the front-rear direction L to the display unit 24 is shortened. Therefore, the wearer can immediately expose the display unit 24 by peeling the surface side member 40 from the rear end portion (or front end portion) of the absorbent article 1, and the wearer can expose the display unit 24. Easy to see.

The front surface side member 40 and the back surface side member 60 may be detachable because they are separate members. As shown in FIG. 3, in order to make the front surface side member 40 and the back surface side member 60 peelable, the absorbent article 1 is provided with a joint portion 70 for joining the front surface side member 40 and the back surface side member 60. It may have a joint region BR and a non-joint region NBR in which the joint portion 70 is not provided. The joint portion 70 may be arranged between the front surface side member 40 and the back surface side member 60 in the thickness direction T.

As shown in FIG. 3, the joint region BR (that is, the joint portion 70) is arranged on the outer peripheral portion of the absorbent article 1 (front side member 40 / back surface side member 60) in a plan view of the absorbent article 1. good. The outer peripheral portion may be composed of an end portion in the front-rear direction L and an end portion in the width direction W of the absorbent article 1. The joint portion 70 may be arranged in a region other than the outer peripheral portion.

The non-bonded region NBR may be arranged at least a part of the end portion of the absorbent article 1 in the anteroposterior direction L. As shown in FIG. 3, the non-bonded region NBR may be arranged at the rear end of the absorbent article 1 in the anteroposterior direction L. The wearer puts a finger in the non-joined region NBR, pinches the skin surface side T1 and the non-skin surface side T2 of the front surface side member 40, and then pulls the front surface side member 40 away from the back surface side member 60 to obtain the front surface. The side member 40 and the back surface side member 60 can be easily peeled off. Further, by arranging the non-bonded region NBR at the rear end portion of the absorbent article 1, even if the front portion of the absorbent article 1 is contaminated with excrement, the wearer does not touch the excrement and the surface side member. 40 can be peeled off from the back surface side member 60.

Further, the non-bonded region NBR may be arranged at the front end portion of the absorbent article 1 in the front-rear direction L. In the case where the absorbent article 1 is attached to the underwear, when the absorbent article 1 is removed from the underwear, the wearer often removes the absorbent article 1 from the front side of the absorbent article 1 which is easy to see. Therefore, when the non-bonded region NBR is arranged at the front end portion of the absorbent article 1 in the front-rear direction L, when the absorbent article 1 is removed from the underwear, the front side of the absorbent article 1 is used with one hand. The portion can be gripped and the fingers of the other hand can be placed in the non-junction region NBR. As a result, the wearer can easily perform the work of peeling off the surface side member 40.

Therefore, the non-bonded region NBR may be arranged at at least one of the front end portion and the rear end portion in the front-rear direction L of the absorbent article 1. The non-bonded region NBR may be arranged at both the front end and the rear end of the absorbent article 1 in the anteroposterior direction L.

The joining region BR (joining portion 70) may be provided by an adhesive or a joining treatment such as embossing by pressure or heat. The non-joining region NBR may be provided by not performing the joining treatment.

Further, in order to make the front surface side member 40 peelable from the back surface side member 60, at least a part of the front surface side member 40 and the back surface side member 60 may be joined by a detachable joint portion 70. The peelable joint 70 may be arranged in at least one of the front side region S1, the rear side region S2, and the central region S3. For example, the joint 70 may be arranged only in the region where the display 24 is located. For example, the joint portion 70 may be arranged only in the rear side region S2, and the non-peelable joint portion 70 may be arranged in the front side region S1 and the central region S3. As a result, the wearer can immediately expose the display unit 24, and the wearer can easily see the display unit 24.

As shown in FIG. 2, the inspection member 20 is arranged between the front surface side member 40 and the back surface side member 60 in the thickness direction T. Therefore, it is arranged on the back surface side member 60.

The inspection member 20 does not have to be fixed to both the front surface side member 40 and the back surface side member 60 by an adhesive or the like. As a result, the fibers constituting the front surface side member 40 and / or the back surface side member 60 can be easily peeled off from the back surface side member 60 without adhering to the inspection member 30. Further, since the fibers do not adhere to the inspection member 30, the display unit 24 can be easily visually recognized.

Alternatively, the inspection member 20 may be joined and fixed to at least one of the front surface side member 40 and the back surface side member 60. As a result, it is possible to prevent the contact portion 22 from being displaced from the first opening 451 and not overlapping with the first opening 451 in the thickness direction T. For example, the inspection member 20 may be joined to the back surface side member 60 by, for example, a hot melt type adhesive (HMA). At least the contact portion 24 does not have to be joined (fixed) in order to prevent the excrement E from coming into contact with the contact portion 22 due to an adhesive or the like. Further, in order to make the display unit 24 easier to see, at least the display unit 22 does not have to be joined (fixed) to the front surface side member 40 and the back surface side member 60. The inspection member 30 may have a fixed portion composed of at least a part other than the contact portion 22 and the display portion 44. At least one of the front surface side member 40 and the back surface side member 60 and the fixed portion of the inspection member 30 may be joined (fixed) by the adhesive applied on the fixed portion. As a result, it is possible to prevent the contact portion 22 from shifting without fixing the contact portion 22 and the display portion 44.

Next, the absorbent article 1 according to the second embodiment will be described with reference to FIG. FIG. 4 is a cross-sectional view of the absorbent article 1 according to the second embodiment. The description of the same part as that of the first embodiment will be omitted.

As shown in FIG. 4, the surface side member 40 may have a first surface side member 42 and a second surface side member 44. The first surface side member 42 may be made of the same material as the above-mentioned top sheet. Therefore, the surface side member 40 may be composed of a plurality of sheets including a top sheet (first surface side member 42).

The second surface side member 44 is a member arranged on the non-skin surface side of the first surface side member 42. The second surface side member 44 may be a liquid permeable sheet. In this case, the second surface side member 44 may be made of the same material as the top sheet. The second surface side member 44 may be a liquid impermeable sheet. In this case, the second surface side member 44 may be made of the same material as the back sheet described above. The first surface side member 42 and the second surface side member 44 may be joined together by, for example, a hot melt type adhesive (HMA).

No opening 45 is formed in the first surface side member 42. On the other hand, the first opening 451 is formed in the second surface side member 44. The openings 45 are formed only in a part of the plurality of sheets constituting the surface side member 40. As a result, the first surface side member 42 covers the first opening 451 and the contact portion 22, so that the inspection member 20 is not exposed. As a result, it is possible to reliably prevent the inspection member from directly touching the wearer's skin. Further, the excrement easily reaches the contact portion 22 by passing through the first opening 451 after passing through the first surface side member 42. Therefore, it is possible to further suppress the deterioration of the wearer's touch and the damage to the skin caused by the indicator while shortening the inspection time and improving the inspection accuracy.

When the second surface side member 44 is a liquid permeable sheet, the first opening 451 is formed in the liquid permeable sheet. Even if the surface-side member 40 has a liquid-impermeable sheet, excrement can pass through the second surface-side member 44 (liquid-impermeable sheet) through the first opening 451. As a result, the excrement can reach the inspection member 20 (contact portion 22), and the health condition of the wearer can be displayed on the display unit 24. On the other hand, the indicator contained in the inspection member 20 may dissolve in the excrement that has reached the inspection member 20. Since the liquid-impermeable sheet, which is the second surface-side member 44, does not allow excrement to pass through except for the first opening 451 can prevent the excrement from returning to the first surface-side member 42. Therefore, damage to the wearer's skin due to the indicator contained in the excrement can be suppressed.

The back surface side member 60 may have a first back surface side member 62 and a second back surface side member 64. The first back surface side member 62 may be a liquid permeable sheet, and may be made of the same material as the above-mentioned top sheet. The first back surface side member 62 may be a sheet (hydrophilic sheet) having a higher hydrophilicity or fiber density than the first front surface side member 42, which is a liquid permeable sheet contained in the front surface side member 40.

As shown in FIG. 4, the inspection member 20 may be arranged on the first back surface side member 62. Therefore, the inspection member 20 may be in (direct) contact with the first back surface side member 62. When the first back surface side member 62 has a higher hydrophilicity or fiber density than the first front surface side member 42, the first back surface side member 62 has a stronger force to draw excrement. Therefore, the excrement (target component) can easily reach the inspection member 20 in a short time. In addition, the excrement is drawn toward the first back surface side member 62 and is difficult to return to the first front surface side member 42. Even if the indicator is dissolved in the excrement, the excrement can be maintained on the first back surface side member 62. The effect of the indicator contained in the excrement on the wearer's skin can be suppressed.

The fiber density can be measured by a well-known method. For example, for the fiber density, the target site is cut out from the absorbent article 1 as a target sample, the mass per unit area of the target sample (g / m ² ) is measured, and the thickness (m) of the target sample is measured to measure the target. It can be calculated by dividing the mass per unit area of the sample by the thickness of the target sample (g / m ³ ). For the mass of fibers per unit area, for example, the mass of the target sample is measured with a direct balance (for example, an electronic balance HF-300 manufactured by Kensei Kogyo Co., Ltd.), the area of the target sample is measured, and the mass per unit area is measured. The mass may be calculated. For the thickness of the target sample, for example, a dial thickness gauge ID-C1012C manufactured by Mitutoyo Co., Ltd. or an equivalent one is used, and the contact area is set to 20 cm ² and the contact pressure is set to ^{3 gf / cm 2.} The site may be pressurized for measurement, visually compared, or an image obtained by photographing a cross section of the absorbent article 1 cut in the longitudinal direction may be used for comparison.

Hydrophilicity can be measured by well-known methods. For example, first, five filter papers are stacked and placed horizontally, and a test piece to be measured is placed on the filter paper. Second, the test pieces are marked at 2 cm intervals in each of the vertical and horizontal directions. Drop one drop of artificial urine (about 0.05 g) into 20 places with a pipette. The artificial urine is dropped at 20 places in 1 minute and 10 seconds. Thirdly, after leaving 20 places for 30 seconds after the completion of dropping, the places absorbed by the test piece are counted. The more absorption points of the test piece, the higher the hydrophilicity. (On the highly hydrophilic side, the ability to absorb liquid is stronger than on the less hydrophilic side.)

The second back surface side member 64 corresponds to the above-mentioned back sheet and may be made of the same material as the above-mentioned back sheet.

Next, the absorbent article 1 according to the third embodiment will be described with reference to FIG. FIG. 5 is a cross-sectional view of the absorbent article 1 according to the third embodiment. The description of the same parts as those of the first and second embodiments will be omitted.

As shown in FIG. 5, the absorbent article 1 may have a second opening 452 that does not overlap the inspection member 20 in the thickness direction T. The second opening 452 may be a through hole penetrating the surface side member 40. As a result, the excrement can reach the first back surface side member 62 in a short time by passing through the second opening 452 as compared with the case where the second opening 452 is not formed.

When the first back surface side member 62 is a liquid permeable sheet, as shown in FIG. 5, the first back surface side member 62 can be diffused to reach the inspection member 20 (contact portion 22). Here, when the absorbent article 1 has only the second opening 452, the inspection member 20 is not exposed when viewed from the skin surface side T1. Therefore, since the inspection member 20 does not come into direct contact with the wearer's skin, deterioration of the wearer's touch can be suppressed, and damage to the skin due to the indicator can be suppressed.

(3) Other Embodiments Although the present invention has been described in detail using the above-described embodiments, the present invention is not limited to the embodiments described in the present specification for those skilled in the art. Is clear. The present invention can be implemented as modifications and modifications without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description of the present specification is for the purpose of exemplification and does not have any limiting meaning to the present invention.

In the second embodiment described above, the first back surface side member 62 may be a sheet (hydrophilic sheet) having a higher hydrophilicity or fiber density than the first front surface side member 42, but is not limited thereto. The first back surface side member 62 may have a higher hydrophilicity or fiber density than all the liquid permeable sheets of the front surface side member 40. As a result, the excrement is drawn toward the first back surface side member 62 and is difficult to return to the front surface side member 40, so that the influence of the indicator contained in the excrement on the wearer's skin can be suppressed.

When the first back surface side member 62 is a sheet (hydrophilic sheet) having a higher hydrophilicity or fiber density than the first front surface side member 42, all the sheets constituting the front surface side member 40 are liquid permeable sheets. May be. Compared with the case where the front surface side member 40 contains a liquid impermeable sheet, excrement easily reaches the back surface side member 60 by diffusion. The excrement that has reached the back surface side member 60 can diffuse the first back surface side member 62 and reach the contact portion 22. Therefore, it is possible to further suppress the deterioration of the wearer's touch and the damage to the skin caused by the indicator while shortening the inspection time and improving the inspection accuracy.

Further, in the above-mentioned second embodiment, the surface side member 40 may have a second opening 452 penetrating the surface side member 40. Thereby, the excrement can be more easily reached to the contact portion 22 by the opening 45 (the first opening 451 and the second opening 452) without exposing the inspection member 20.

In each of the above embodiments, the first surface side member 42 is composed of one or two sheets, but is not limited thereto. The first surface side member 42 may be composed of three or more sheets. For example, the first surface side member 42 has three layers in which a liquid impermeable sheet (second surface side member) is sandwiched between two liquid permeable sheets (first and third surface side members) in the thickness direction T. It may be composed of a sheet of. As a result, excrement diffuses through the liquid permeable sheet (third surface side member) arranged on the non-skin surface side of the liquid permeable sheet (second surface side member). The excrement also easily comes into contact with the skin surface side T1 of the inspection member 20. The liquid-impermeable sheet can prevent the excrement (target component) required for the inspection from reaching the contact portion 22 in a short time while suppressing damage to the wearer's skin due to the indicator contained in the excrement. When the surface side member 40 contains a liquid permeable sheet, at least the liquid permeable sheet has holes to move excrement to the non-skin surface side T2 rather than the liquid permeable sheet. It is formed.

Further, similarly to the front surface side member 40, the back surface side member 60 may be composed of three or more sheets. For example, when the back surface side member 60 includes a hydrophilic sheet having a higher hydrophilicity or fiber density than the liquid permeable sheet contained in the front surface side member, the hydrophilic sheet does not have to be arranged on the inspection member 20. .. That is, the hydrophilic sheet does not have to come into contact with the inspection member 20. A liquid permeable sheet may be arranged between the hydrophilic sheet and the inspection member 20 in the thickness direction T. The hydrophilic sheet may make it difficult for the excrement to return to the surface side member 40 by drawing the excrement through the liquid permeable sheet.

In the above-described embodiment, when the front surface side member 40 is peeled off from the back surface side member 60, the back surface side member 60 may be fixed and the front surface side member 40 may be peeled off from the back surface side member 60. Further, the front surface side member 40 may be fixed and the back surface side member 60 may be peeled off from the front surface side member 40. As a result, the front surface side member 40 can be peeled off from the back surface side member 60.

In the above-described embodiment, the inspection member 20 has a linear plate shape. In this embodiment, the inspection member 20 may have, for example, one or more creases. Therefore, the inspection member 20 may have, for example, a two-fold or three-fold shape. The inspection member 20 may be composed of a member folded in a Z shape. As a result, the inspection member 20 can be arranged inside the absorbent article 1 in a compact state. Since the area of the inspection member 20 is reduced, it is possible to easily suppress the deterioration of the wearer's touch due to the inspection member 20.

Further, the inspection member 20 may be arranged in a folded state so that the contact portion 22 comes into contact with at least one of the front surface side member 40 and the back surface side member 60. As a result, even if the inspection member 20 is broken, the excrement can easily reach the contact portion 22.

Further, the inspection member 20 may be arranged in a folded state so that the display unit 22 is in contact with at least one of the front surface side member 40 and the back surface side member 60. As a result, even if the inspection member 20 is folded, the wearer can visually recognize the display unit 22 as soon as the surface side member 40 is peeled off. As a result, the wearer can easily confirm the health condition.

Further, the inspection member 20 may be configured such that the tape member for the post-treatment tape having the adhesive portion has the contact portion 22 and the display portion 24. The adhesive portion of the inspection member 20 as a tape member for the post-treatment tape may fix the absorbent article 1 after use in a rolled state so that the skin contact surface is not exposed. By using the inspection member 20 as the tape member, the absorbent article can be hygienically disposed of. In this way, the wearer can use the inspection member 20 as a tape member for the post-treatment tape after inspecting the health condition, and can effectively utilize the inspection member 20. The tape member for the post-treatment tape may have a Z-shaped folded shape as described above.

The wearer may acquire the inspection information by sending the coloration information (image information and / or video information) indicating the coloration of the display unit 24 to the network (management server). For example, the wearer presents the exposed display unit 24 by peeling the front surface side member 40 from the back surface side member 60 and then photographing the exposed display unit 24 with, for example, a camera built in a communication device owned by the wearer (user). Color information may be acquired. The wearer can send the coloration information to the management server via the communication device. The wearer may send user information indicating the wearer's information together with the coloration information. The user information may be, for example, at least one of a user identifier, a communication device identifier, information indicating the type of excrement, information indicating the type of the absorbent article 1 (inspection member 20), information specifying the target component, and the like. be.

In addition, the wearer may house the absorbent article 1 including the test member 20 or the test member 20 itself in a storage device capable of detecting a color reaction caused by an indicator. The accommodating device may irradiate the display unit 24 with visible light in order to detect the color reaction. The accommodating device is special to the inspection member 20 which can confirm the coloration by the indicator by irradiating special light having a special wavelength different from visible light (for example, ultraviolet rays having a wavelength shorter than visible light). The display unit 24 may be irradiated with light having a wavelength. The accommodating device may acquire coloration information by taking a picture while irradiating visible light or special light in the accommodating device. In this way, by photographing the display unit 24 while irradiating light in the accommodating device, it is possible to accurately confirm the coloration without being affected by the surrounding environment.

The accommodating device may send the coloration information acquired by photographing the display unit 24 to the network (management server). In this case, the accommodating device may include the identifier of the accommodating device as the user information. In addition, the accommodating device may send the acquired coloration information to a communication device owned by the wearer. The wearer may determine the presence or absence of coloration by displaying the display unit 24 on the communication device. As a result, the wearer can confirm the health condition more accurately. The wearer may send the coloration information acquired from the accommodating device to the network via the communication device in the same manner as described above.

The management server can determine the health condition of the wearer (user) based on the coloration information (and user information). The management server may transmit information indicating the determination result to the communication device that is the source of the coloration information. The management server may transmit the advice information indicating the advice based on the determination result to the communication device together with the determination information indicating the determination result. The management server, even when receiving color information from the containment device, is associated with the associated communication device (ie, the user's identifier) based on the communication device identifier (user identifier) associated with the containment device identifier. Judgment information (and advice information) may be transmitted to (a communication device owned by the user).

The communication device may display the determination result based on the determination information received by the communication device. As a result, the wearer can grasp the health condition from the displayed determination result. The wearer can obtain an objective judgment result, not based on the wearer's own judgment. Further, when the communication device receives the advice information, the communication device may display the advice. This allows the wearer to grasp the advice.

The communication device has a program for executing the various processes described above. The communication device has a memory for storing a program and a processor for executing the program stored in the memory. The program may be available on the network (eg, management server).
