　本発明のトイレトレーニング用インジケータは、吸収性物品用のトイレトレーニング用インジケータであって、幼児の生育状態による尿への応答が異なり、トイレトレーニングの開始時期を示すものである。 《Toilet training indicator》
The toilet training indicator of the present invention is a toilet training indicator for absorbent articles, and the response to urine differs depending on the growth state of the infant, indicating the start time of toilet training.
〈呈色反応〉
　本開示に係る１つの実施態様では、トイレトレーニング用インジケータが、幼児の生育状態によって尿への異なる呈色反応を示す。この態様では、例えば、トイレトレーニング用インジケータを含有する担体が吸収性物品を構成する資材に適用されており、当該担体に含有されるインジケータが、幼児の生育状態に応じて異なる色調を示す。呈色の度合いは、肉眼で判定してもよく、又は光学的に反射率で測定してもよい。肉眼で呈色の度合いを判定する場合には、例えば、あらかじめ作成した標準色調表（色見本）などの色調と比較することによって、肉眼判定を行ってよい。あるいは、呈色の度合いを測定する場合には、スマートフォンなどによって撮影したインジケータの画像を、スマートフォンなどにインストールされた画像処理プログラムによって処理することによって、インジケータの呈色の度合いを判定してもよい。 <Color reaction>
In one embodiment of the present disclosure, the potty training indicator exhibits different color reactions to urine depending on the growing condition of the infant. In this aspect, for example, a carrier containing a toilet training indicator is applied to a material constituting an absorbent article, and the indicator contained in the carrier exhibits a different color tone depending on the growth state of the infant. The degree of color development may be determined with the naked eye, or may be optically measured by reflectance. When determining the degree of coloration with the naked eye, the determination may be made with the naked eye, for example, by comparing with a color tone such as a standard color tone table (color sample) prepared in advance. Alternatively, when measuring the degree of coloration, the degree of coloration of the indicator may be determined by processing the image of the indicator taken by the smartphone or the like with an image processing program installed in the smartphone or the like. ..
〈尿比重〉 <Urine specific gravity>
　本発明の１つの実施形態に係るトイレトレーニング用インジケータは、尿比重の値に応じて異なる応答を示すインジケータである。 The toilet training indicator according to one embodiment of the present invention is an indicator showing different responses depending on the value of urine specific gravity.
　尿比重は、尿比重の値に応じて異なる呈色反応を示す試薬（検出用化合物又は検出用組成物）を用いて計測してもよく（試験紙法など）、屈折計を用いて尿屈折率を計測することによって計測してもよく、又は浸透圧を利用した方法によって計測してもよい。 Urine specific gravity may be measured using a reagent (detection compound or detection composition) that exhibits different color development reactions depending on the value of urine specific gravity (test paper method, etc.), or urine refraction using a refractometer. It may be measured by measuring the rate, or it may be measured by a method using osmotic pressure.
　尿比重の値に応じて異なる反応を示すトイレトレーニング用インジケータを用いてトイレトレーニングの開始時期の目安を把握するためには、特定の尿比重値をしきい値として設定することが好ましい。例えば、尿比重値が当該しきい値以上になったことを、トイレトレーニングの開始時期の目安とすることができる。尿比重値の検出範囲が例えば１．００００～１．０４００である場合には、尿比重値が１．０２５０以上、１．０２６０以上、１．０２７０以上、１．０２８０以上、１．０２９０以上、１．０３００以上、１．０３１０以上、１．０３２０以上、１．０３３０以上、１．０３４０以上、又は１．０３５０以上である場合を、トイレトレーニングの開始時期の目安として設定してよい。尿比重の値は、幼児の健康状態、水分摂取、食事制限、運動負荷、発汗、季節などの要因によって変動する場合がある。したがって、このような尿比重の変動を考慮してしきい値を設定することが好ましく、特には、尿比重の変動を考慮して、しきい値を場合に応じて複数設定すること、及び／又は、尿比重の変動に応じてしきい値を補正することが好ましい。なお、同様のことは、尿比重以外の原理を用いたインジケータについても当てはまる。 It is preferable to set a specific urine specific gravity value as a threshold value in order to grasp a guideline for the start time of toilet training using a toilet training indicator that shows a different reaction depending on the value of urine specific gravity. For example, the fact that the urine specific gravity value exceeds the threshold value can be used as a guideline for the start time of toilet training. When the detection range of the urine specific gravity value is, for example, 1.000 to 1.0400, the urine specific gravity value is 1.0250 or more, 1.0260 or more, 1.0270 or more, 1.0280 or more, 1.0290 or more. The case of 1.0300 or more, 1.0310 or more, 1.0320 or more, 1.0330 or more, 1.0340 or more, or 1.0350 or more may be set as a guideline for the start time of toilet training. The value of urine specific gravity may fluctuate depending on factors such as the health condition of the infant, water intake, dietary restrictions, exercise load, sweating, and season. Therefore, it is preferable to set the threshold value in consideration of such fluctuation of urine specific gravity, and in particular, in consideration of the fluctuation of urine specific gravity, a plurality of threshold values may be set depending on the case, and / Alternatively, it is preferable to correct the threshold value according to the fluctuation of urine specific gravity. The same applies to indicators using principles other than urine specific gravity.
《緩衝剤、ｐＨ指示薬、及び界面活性剤の組み合わせから構成される検出用組成物》

　理論によって限定する意図はないが、このような検出用組成物を含むインジケータでは、界面活性剤が可溶化、湿潤効果を示すだけではなく、通常は塩の添加で促進されるｐＨ指示薬の解離を逆に抑制する作用も示すため、結果として、塩の添加による緩衝剤のｐＨ変化に伴うｐＨ指示薬の吸光度（ＯＤ）変化が増大すると考えられる。 Although not intended to be limited by theory, indicators containing such detection compositions not only show a solubilizing and wetting effect on the surfactant, but also dissociate the pH indicator, which is usually promoted by the addition of salts. On the contrary, it also exhibits an inhibitory effect, and as a result, it is considered that the change in the absorbance (OD) of the pH indicator accompanying the change in the pH of the buffer agent due to the addition of the salt increases.
　緩衝剤、ｐＨ指示薬、及び界面活性剤の組み合わせから構成される検出用組成物は、例えば、緩衝剤、ｐＨ指示薬、及び界面活性剤を、蒸留水などの溶媒に溶解させて溶液を調製し、この溶液を吸収性物品を構成する資材に適用することによって、用いてよい。 A detection composition composed of a combination of a buffer, a pH indicator, and a surfactant prepares a solution by dissolving, for example, the buffer, the pH indicator, and the surfactant in a solvent such as distilled water. This solution may be used by applying it to the materials that make up the absorbent article.

〈高分子電解質及びｐＨ指示薬の組み合わせから構成される検出用組成物〉
　本開示に係る別の実施態様では、尿比重の値に応じて異なる呈色反応を示すインジケータが、高分子電解質及びｐＨ指示薬の組み合わせを含む検出用組成物を含んでいる。理論によって限定する意図はないが、当該検出用組成物をインジケータとして用いた場合には、尿中に含まれる陽イオンが、高分子電解質によってプロトンに交換され、このプロトンがｐＨ指示薬を変色させると考えられる。尿中に含まれる陽イオンの濃度は尿比重に比例すると考えられるため、高分子電解質及びｐＨ指示薬の組み合わせによって得られる呈色反応によって、尿比重を測定することができる。 <Detection composition composed of a combination of a polymer electrolyte and a pH indicator>
In another embodiment according to the present disclosure, an indicator showing different color reactions depending on the value of urine specific gravity comprises a detection composition comprising a combination of a polyelectrolyte and a pH indicator. Although not intended to be limited by theory, when the detection composition is used as an indicator, cations contained in urine are exchanged for protons by a polyelectrolyte, and these protons discolor the pH indicator. Conceivable. Since the concentration of cations contained in urine is considered to be proportional to the specific gravity of urine, the specific gravity of urine can be measured by the color reaction obtained by the combination of the polyelectrolyte and the pH indicator.
（高分子電解質）
　高分子電解質としては、酸基を有する水溶性高分子化合物を用いることが好ましく、例えば、メトキシエチレン無水マレイン酸共重合体、ポリスチレンスルホン酸、及びポリビニル硫酸等を挙げることができる。 (Polyelectrolyte)
As the polymer electrolyte, it is preferable to use a water-soluble polymer compound having an acid group, and examples thereof include a methoxyethylene maleic anhydride copolymer, polystyrene sulfonic acid, and polyvinyl sulfate.
（ｐＨ指示薬）
　ｐＨ指示薬については、上記の記載を参照することができる。 (PH indicator)
For the pH indicator, the above description can be referred to.
〈陽イオン〉
　本発明のさらに別の実施形態では、尿中の陽イオンを検出対象とすることもできる。幼児においては、腎機能の発達に伴い、尿中の陽イオンの濃度が変化するので、陽イオンを検出対象物質とすることにより、トイレトレーニングの開始時期の目安を把握することができる。また、トイレトレーニング用インジケータの検出対象物質への応答として、呈色反応を利用することにより、トイレトレーニングの開始時期の目安を視覚的に把握することができる。 <Cation>
In still another embodiment of the present invention, cations in urine can be detected. In infants, the concentration of cations in urine changes with the development of renal function, so by using cations as the detection target substance, it is possible to grasp the guideline for the start time of toilet training. In addition, by using the color reaction as a response to the substance to be detected by the toilet training indicator, it is possible to visually grasp the guideline of the start time of the toilet training.
　ここで、本実施形態のトイレトレーニング用インジケータが検知する陽イオンとしては、主として、ナトリウムイオン及びカリウムイオン等の１価の陽イオンを挙げることができる。尿における陽イオンの濃度を計測する方法は、特に限定されないが、上述の高分子電解質及びｐＨ指示薬の組み合わせを含む試薬組成物を用いた呈色反応によって計測する方法が挙げられる。 Here, as the cation detected by the toilet training indicator of the present embodiment, mainly monovalent cations such as sodium ion and potassium ion can be mentioned. The method for measuring the concentration of cations in urine is not particularly limited, and examples thereof include a method for measuring by a color reaction using a reagent composition containing the above-mentioned combination of a polymer electrolyte and a pH indicator.
　本発明の実施形態におけるトイレトレーニング用インジケータは、所定濃度以上の尿中物質に応答するように、検出用化合物又は検出用組成物等の種類や適用量が調整されていることが好ましい。 It is preferable that the type and application amount of the detection compound, the detection composition, or the like of the toilet training indicator in the embodiment of the present invention are adjusted so as to respond to the urinary substance having a predetermined concentration or higher.
〈ＳＡＰ〉
　トイレトレーニング開始時期の目安の把握方法については、上述の検出用組成物以外にも、例えば、吸収体に用いられる高吸水性高分子（ＳＡＰ）の崩壊を利用したインジータを利用してもよい。例えば、アスコルビン酸や鉄によってＳＡＰの崩壊が発生しやすくなること、及び、アスコルビン酸や鉄が乳幼児の年齢（月齢）が高くなるほど増加することを利用して、尿中のアスコルビン酸や鉄が所定値より高い場合に崩壊するＳＡＰをインジケータの試薬として使用することにより、トイレトレーニングの開始時期の目安を把握することができる。 <SAP>
As a method for grasping the guideline of the toilet training start time, for example, an indeta using the disintegration of the super absorbent polymer (SAP) used for the absorber may be used in addition to the above-mentioned detection composition. For example, ascorbic acid and iron in urine are prescribed by taking advantage of the fact that SAP is more likely to collapse due to ascorbic acid and iron, and that ascorbic acid and iron increase as the age (month) of infants increases. By using SAP, which disintegrates when the value is higher than the value, as a reagent for the indicator, it is possible to grasp a guideline for the start time of toilet training.
　そのようなインジケータとしては、例えば、ポリアクリル酸ナトリウムなどの特定のＳＡＰが挙げられる。ポリアクリル酸ナトリウムは、発達がある程度進行した幼児の尿に接触すると、ゲル状構造が不安定化し、少なくとも部分的に液状化する。したがって、ポリアクリル酸ナトリウムをトイレトレーニング用インジケータとして使用することによって、トイレトレーニングの開始時期の目安を把握することができる。 Such indicators include, for example, specific SAPs such as sodium polyacrylate. When sodium polyacrylate comes into contact with the urine of a developed infant, the gel-like structure becomes unstable and at least partially liquefies. Therefore, by using sodium polyacrylate as an indicator for toilet training, it is possible to grasp a guideline for the start time of toilet training.
　また、ＳＡＰは、幼児用オムツにおいて吸収性物品として使用することができるため、専用のインジケータを別途用意する必要がないという観点からも、ＳＡＰをトイレトレーニング用インジケータとして使用することは、特に有利である。 In addition, since SAP can be used as an absorbent article in infant diapers, it is particularly advantageous to use SAP as an indicator for toilet training from the viewpoint that it is not necessary to separately prepare a dedicated indicator. be.
　理論によって限定する意図はないが、上述のＳＡＰが幼児の生育状態によって尿への反応が異なるメカニズムは、尿中におけるアスコルビン酸及び鉄の量変化に関係していると考えられる。すなわち、低月齢児（乳幼児）では、母乳に含まれる鉄の含有量が低い上に造血が盛んであることに起因して、鉄の排出が抑制されており、一方で、高月齢児では、摂食の質及び量の変化に伴って鉄の排出量が増加していると考えられる。非ヘム鉄の吸収に関与するアスコルビン酸についても、同様に、低月齢児では排出量が低く、高月齢児では排出量が高くなっていると考えられる。したがって、上述のＳＡＰは、低月齢児の尿と接触しても構造がほとんど変化しないが、高月齢児の尿に比較的多量に含まれるアスコルビン酸及び鉄によって、ゲル構造が不安定化すると考えられる。 Although not intended to be limited by theory, the mechanism by which the above-mentioned SAP responds differently to urine depending on the growth state of the infant is considered to be related to changes in the amounts of ascorbic acid and iron in urine. That is, in young children (infants), iron excretion is suppressed due to the low iron content in breast milk and active hematopoiesis, while in older children, iron is suppressed. It is considered that iron emissions are increasing with changes in the quality and quantity of food intake. Similarly, ascorbic acid, which is involved in the absorption of non-heme iron, is considered to have low emissions in young children and high in older children. Therefore, it is considered that the above-mentioned SAP has almost no change in structure even when it comes into contact with the urine of a young child, but the gel structure is destabilized by ascorbic acid and iron contained in a relatively large amount in the urine of an old child. Be done.
　〈その他の検出対象物質と作用する検出反応物質を含むトイレトレーニング用インジケータ〉
　本発明のトイレトレーニング用インジケータは、上記以外の検出用試薬（検出用化合物又は検出用組成物）であってもよい。そのような検出用試薬としては、例えば、ｐＨ指示薬（尿の水素イオンやたんぱく質に応答）、スルファニルアミド（尿中の亜硝酸塩に応答）、ニトロブルシドナトリウム水和物（尿中のケトン体に応答）、グルコースオキシダーゼとペルオキシダーゼと還元性色原体の組み合わせ（尿中のブドウ糖に応答）、ジアゾニウム塩（尿中のビリルビンに応答）等を含む。このような検出用試薬を含むトイレトレーニング用インジケータも、本発明の範囲内に含まれるものである。 <Toilet training indicator containing detection reactants that act with other substances to be detected>

　表１で見られるように、平均尿比重値が１．０２９２～１．０３３３であった実施例１～６の場合には、トイレトレーニングを行うことによって、オムツを卒業することができた。一方で、平均尿比重が１．０２５８～１．０２８３であった比較例１～５の場合には、トイレトレーニングを行っても、オムツを卒業することができなかった。 As can be seen in Table 1, in the cases of Examples 1 to 6 in which the average urine specific gravity value was 1.0292 to 1.0333, the diaper could be graduated by performing toilet training. On the other hand, in the cases of Comparative Examples 1 to 5 in which the average urine specific gravity was 1.0258 to 1.0283, even if toilet training was performed, the diaper could not be graduated.
　特に、比較例１と実施例１は、同じ幼児についての結果を示している。平均尿比重が１．０２６１であった時点（比較例１）では、トイレトレーニングを行ってもオムツを卒業することができなかったが、平均尿比重が１．０３０６であった時点（実施例１）では、トイレトレーニングを行うことによってオムツを卒業できたことがわかる。なお、比較例３と実施例２も、同じ幼児についての結果を示しており、同様のことがいえる。 In particular, Comparative Example 1 and Example 1 show the results for the same infant. At the time when the average urine specific gravity was 1.0261 (Comparative Example 1), the diaper could not be graduated even after toilet training, but when the average urine specific gravity was 1.0306 (Example 1). In), it can be seen that diapers could be graduated by performing toilet training. In addition, Comparative Example 3 and Example 2 also show the results for the same infant, and the same can be said.
　なお、尿比重値は腎機能の発達とともに増加するため、年齢（月齢）と尿比重との間には、ある程度の相関があると考えられる。しかしながら、年齢と尿比重との相関は弱いものであり、実際、上記の表１を見ても、年齢が比較的低いにもかかわらず尿比重値が比較的高い場合（実施例６など）がある一方で、年齢が比較的高くても尿比重値が比較的低い場合（比較例２、３など）場合がある。したがって、年齢と尿比重値との間にある程度の相関関係があるからといって、尿比重値の代わりに年齢のみを指標としてトイレトレーニングの開始時期を判断できるものではないことが、上記の結果から明らかである。むしろ、尿比重値は、幼児がトイレトレーニングに適した発達段階になっていることを判断するうえで、年齢からは読み取ることのできない指標を与えるものである。 Since the urine specific gravity value increases with the development of renal function, it is considered that there is some correlation between age (month age) and urine specific gravity. However, the correlation between age and urine specific gravity is weak, and in fact, even when looking at Table 1 above, there are cases where the urine specific gravity value is relatively high despite the relatively young age (Example 6 and the like). On the other hand, there are cases where the urine specific gravity value is relatively low even if the age is relatively high (Comparative Examples 2, 3 and the like). Therefore, even if there is a certain degree of correlation between age and urine specific gravity, it is not possible to determine when to start toilet training using only age as an index instead of urine specific gravity. It is clear from. Rather, the urine specific gravity value provides an index that cannot be read from age in determining that the infant is at a developmental stage suitable for potty training.
　上述の実施例及び比較例から、幼児の生育状態による尿への応答が異なる吸収性物品用のトイレトレーニング用インジケータを用いることによって、トイレトレーニングの開始時期を的確に把握することができることがわかった。 From the above-mentioned Examples and Comparative Examples, it was found that the start time of toilet training can be accurately grasped by using the toilet training indicator for absorbent articles having different responses to urine depending on the growth state of the infant. ..
