[overall structure]
FIG. 1: shows schematic structure at the time of seeing the diaper of Embodiment 1 which concerns on this invention from the top. In FIG. 1, symbols L1, L2, and L3 respectively correspond to the abdomen portion, the crotch portion, and the dorsal portion of the diaper user. The X direction in FIG. 1 indicates the longitudinal direction, and the Y direction indicates the width direction. FIG. 2 is a sectional view taken along line AA of the crotch portion L2 in the diaper 10A of FIG. As shown in FIG.1 and FIG.2, the diaper 10A of Embodiment 1 has the inner sheet | seat 11 which permeate | transmits a liquid, the waterproof outer sheet | seat 12, the absorber 13 which absorbs excrement, and the leakage of excrement. The gather 14 to prevent and the some excretion detection elements 20a, 20b, 20c, 20d which detect excrement are provided. Moreover, in Embodiment 1, the diaper 10A includes a tape 15 for mounting the diaper 10A. In the present specification, the excretion detection elements 20a, 20b, 20c, and 20d may be referred to as the excretion detection element 20.
　内面シート１１は、おむつ使用者のからだが接触するおむつ１０Ａの内側の内面領域を形成するシートである。内面シート１１は、液体を透過する材料で作られており、おむつ使用者が排泄した際に、排泄物である尿を素早く吸収体１３へ送り込む。例えば、内面シート１１は、ポリエステル又はポリプロピレンの不織布等で作られている。 The inner surface sheet 11 is a sheet that forms an inner surface region inside the diaper 10A that comes into contact with the diaper user's body. The inner surface sheet 11 is made of a material that allows liquid to pass through. When the diaper user excretes, the urine, which is excreted, is quickly fed into the absorber 13. For example, the inner surface sheet 11 is made of polyester or polypropylene nonwoven fabric.
　外面シート１２は、おむつ１０Ａの外側を覆う防水のシート、即ち液体を透過しないシートである。外面シート１２は、排泄物である尿を漏らさず、水蒸気を外に逃がすような通気性を有する素材で作られている。外面シート１２は、内面シート１１と吸収体１３とを覆い、排泄物の漏れを防止している。 The outer surface sheet 12 is a waterproof sheet that covers the outside of the diaper 10A, that is, a sheet that does not transmit liquid. The outer sheet 12 is made of a breathable material that does not leak excrement urine and allows water vapor to escape outside. The outer sheet 12 covers the inner sheet 11 and the absorber 13 and prevents the excrement from leaking.
　吸収体１３は、尿などの排泄物を吸収するものである。吸収体１３は、内面シート１１と外面シート１２との間に配置されている。吸収体１３は、おむつ１０Ａの腹側部分Ｌ１から股下部分Ｌ２を通って背側部分Ｌ３まで、長手方向である図１のＸ方向に向かって延びている。吸収体１３は、例えば、略長方形の形状を有している。吸収体１３は、例えば、吸水紙、線状パルプ、高分子吸水材などを組み合わせて構成している。 The absorber 13 absorbs excrement such as urine. The absorber 13 is disposed between the inner sheet 11 and the outer sheet 12. The absorbent body 13 extends from the ventral part L1 of the diaper 10A through the crotch part L2 to the back part L3 in the X direction of FIG. The absorber 13 has, for example, a substantially rectangular shape. The absorber 13 is configured by combining, for example, water-absorbing paper, linear pulp, polymer water-absorbing material, and the like.
　ギャザー１４は、排泄物の漏れを防止するものである。ギャザー１４は、例えば、股下部分Ｌ２の幅方向である図１のＹ方向への尿漏れを防止している。ギャザー１４は、例えば、不織布と伸縮性素材で作られている。ギャザー１４は、吸収体１３の幅方向の両側部に配置されると共に、吸収体１３の長手方向に沿って延びている。ギャザー１４は、第１弾性部材１４ａ及び第２弾性部材１４ｂを備えている。第１弾性部材１４ａ及び第２弾性部材１４ｂは、図２に示すように、内面シート１１で形成される内面領域において、内面シート１１に対して外面シート１２が配置されている方向とは反対方向へ突設される。第１弾性部材１４ａは、第２弾性部材１４ｂより吸収体１３の近くに配置されている。第１弾性部材１４ａ及び第２弾性部材１４ｂは、おむつ使用者がおむつ１０Ａを装着したとき、おむつ使用者のからだを包み込み、股下部分Ｌ２からの尿の横漏れを防止している。 The gather 14 prevents the excrement from leaking. The gather 14 prevents, for example, urine leakage in the Y direction of FIG. 1 which is the width direction of the crotch portion L2. The gather 14 is made of, for example, a nonwoven fabric and a stretchable material. The gathers 14 are disposed on both sides in the width direction of the absorbent body 13 and extend along the longitudinal direction of the absorbent body 13. The gather 14 includes a first elastic member 14a and a second elastic member 14b. As shown in FIG. 2, the first elastic member 14 a and the second elastic member 14 b are opposite to the direction in which the outer sheet 12 is disposed with respect to the inner sheet 11 in the inner region formed by the inner sheet 11. Is projected. The first elastic member 14a is disposed closer to the absorber 13 than the second elastic member 14b. When the diaper user wears the diaper 10A, the first elastic member 14a and the second elastic member 14b wrap the body of the diaper user and prevent side leakage of urine from the crotch portion L2.
　排泄検知素子２０は、排泄物に接触することにより、通信不可能となることで排泄物を検知する素子である。図１に示すように、排泄検知素子２０は、おむつ１０Ａの内面領域において吸収体１３の外側領域に配置されている。図１及び図２に示すように、排泄検知素子２０ａ、２０ｂは、股下部分Ｌ２において、ギャザー１４上に配置されている。より具体的には、排泄検知素子２０ａ、２０ｂは、内面領域においてギャザー１４に対して吸収体１３が配置されている側とは反対側に配置されている。また、排泄検知素子２０ｃは、内面領域において腹側部分Ｌ１の吸収体１３の外側領域に配置されている。排泄検知素子２０ｄは、内面領域において背側部分Ｌ３の吸収体１３の外側領域に配置されている。 The excretion detection element 20 is an element that detects excretion when communication with the excrement becomes impossible due to contact with the excretion. As shown in FIG. 1, the excretion detection element 20 is disposed in the outer region of the absorber 13 in the inner surface region of the diaper 10A. As shown in FIG.1 and FIG.2, the excretion detection elements 20a and 20b are arrange | positioned on the gather 14 in the crotch part L2. More specifically, the excretion detection elements 20a and 20b are disposed on the side opposite to the side on which the absorber 13 is disposed with respect to the gather 14 in the inner surface region. Moreover, the excretion detection element 20c is arrange | positioned in the outer area | region of the absorber 13 of the ventral part L1 in an inner surface area | region. The excretion detection element 20d is arranged in the outer region of the absorber 13 of the back portion L3 in the inner surface region.
　排泄検知素子２０について、図３を用いて詳細に説明する。図３は、排泄検知素子２０の概略構成を示す。図３に示すように、排泄検知素子２０は、無線ＩＣチップ２１と、整合回路２２と、放射電極２３と、を備える。実施の形態１においては、無線ＩＣチップ２１は、ＲＦＩＣチップを用いている。 The excretion detection element 20 will be described in detail with reference to FIG. FIG. 3 shows a schematic configuration of the excretion detection element 20. As shown in FIG. 3, the excretion detection element 20 includes a wireless IC chip 21, a matching circuit 22, and a radiation electrode 23. In the first embodiment, the wireless IC chip 21 uses an RFIC chip.
　無線ＩＣチップ２１は、電池を内蔵しないパッシブタイプのものであり、所定周波数の送受信信号を処理する。無線ＩＣチップ２１は、整合回路２２と電気的に接続されている。 The wireless IC chip 21 is a passive type that does not incorporate a battery, and processes transmission / reception signals of a predetermined frequency. The wireless IC chip 21 is electrically connected to the matching circuit 22.
　整合回路２２は、インダクタとコンデンサとを備え、所定の共振周波数を有する共振回路を構成している。整合回路２２は、無線ＩＣチップ２１と放射電極２３とのインピーダンスマッチングを図るものであり、無線ＩＣチップ２１と放射電極２３との両方に接続されている。 The matching circuit 22 includes an inductor and a capacitor, and constitutes a resonance circuit having a predetermined resonance frequency. The matching circuit 22 is for impedance matching between the wireless IC chip 21 and the radiation electrode 23, and is connected to both the wireless IC chip 21 and the radiation electrode 23.
　放射電極２３は、リーダライタ等の外部からの信号を受信すると共に、無線ＩＣチップ２１からの信号を放射するアンテナである。放射電極２３は、整合回路２２と電気的に導通した状態で接続されている。実施の形態１においては、放射電極２３は、ダイポール型アンテナが使用されている。 The radiation electrode 23 is an antenna that receives a signal from the outside such as a reader / writer and radiates a signal from the wireless IC chip 21. The radiation electrode 23 is connected to the matching circuit 22 in an electrically conductive state. In the first embodiment, the radiation electrode 23 is a dipole antenna.
　排泄検知素子２０は、内面領域において吸収体１３の外側領域に配置されることにより、吸収体１３の尿吸収限界を超えて吸収体１３の外側領域へ漏れた尿を検知している。あるいは、おむつ１０Ａが正常に装着されていない場合に、内面領域において吸収体１３の外側領域へ漏れた尿を検知している。おむつ１０Ａが正常に装着されていない場合とは、おむつ使用者がおむつ１０Ａをずれた状態で装着している場合等を意味する。実施の形態１においては、内面領域において、ギャザー１４に対して吸収体１３が配置されている側とは反対側に排泄検知素子２０ａ、２０ｂを配置しているため、ギャザー１４の外側に漏れた尿を検知することができる。また、排泄検知素子２０ｃは、内面領域において、腹側部分Ｌ１の吸収体１３の外側領域へ漏れた尿を検知することができる。排泄検知素子２０ｄは、内面領域において、背側部分Ｌ３の吸収体１３の外側領域へ漏れた尿を検知することができる。 The excretion detection element 20 detects urine leaking to the outer region of the absorber 13 beyond the urine absorption limit of the absorber 13 by being disposed in the outer region of the absorber 13 in the inner surface region. Or the urine which leaked to the outer side area | region of the absorber 13 in the inner surface area | region is detected when 10 A of diapers are not mounted | worn normally. The case where the diaper 10A is not normally worn means that the diaper user is wearing the diaper 10A in a shifted state. In Embodiment 1, since the excretion detection elements 20a and 20b are arranged on the side opposite to the side where the absorber 13 is arranged with respect to the gather 14 in the inner surface region, it leaks outside the gather 14. Urine can be detected. Further, the excretion detection element 20c can detect urine leaking to the outer region of the absorber 13 of the ventral portion L1 in the inner surface region. The excretion detection element 20d can detect urine leaking to the outer region of the absorber 13 of the back portion L3 in the inner surface region.
　図４は、おむつ１０Ａを使用したシステムの例を示す。図４に示すように、おむつ１０Ａを使用したシステムは、おむつ１０Ａと、リーダライタ３１と、送信ユニット３２と、通信モジュール３３と、を備える。 FIG. 4 shows an example of a system using the diaper 10A. As shown in FIG. 4, the system using the diaper 10 </ b> A includes a diaper 10 </ b> A, a reader / writer 31, a transmission unit 32, and a communication module 33.
　リーダライタ３１は、おむつ１０Ａの排泄検知素子２０と通信するものである。送信ユニット３２は、通信モジュール３３に信号を送信するものである。通信モジュール３３は、送信ユニット３２から信号を受信し、おむつ１０Ａが使用限界を超えたことを介護者に知らせるものである。なお、図示していないが、これらの要素は、コンピュータ等の制御部によって制御されるものである。 The reader / writer 31 communicates with the excretion detection element 20 of the diaper 10A. The transmission unit 32 transmits a signal to the communication module 33. The communication module 33 receives a signal from the transmission unit 32 and notifies the caregiver that the diaper 10A has exceeded the use limit. Although not shown, these elements are controlled by a control unit such as a computer.
　内面領域において吸収体１３の外側領域に配置された排泄検知素子２０は、排泄物と接触していない場合、外部装置であるリーダライタ３１と通信可能な状態である。そのため、リーダライタ３１は、排泄検知素子２０からの信号を読み取ることができる。この場合、リーダライタ３１は、内面領域において吸収体１３の外側領域へ尿が漏れていないと判定することができる。一方、排泄検知素子２０が排泄物に接触した場合、排泄検知素子２０は通信不可能な状態となる。そのため、リーダライタ３１は、排泄検知素子２０の信号を読み取ることができなくなる。この場合、リーダライタ３１は、内面領域において吸収体１３の外側領域に尿が漏れていると判定し、送信ユニット３２を介して、通信モジュール３３へ信号を送信する。通信モジュール３３とは、例えば、スマートフォン、コントローラ等である。通信モジュール３３は、おむつ交換などの表示をすることにより、介護者におむつ１０Ａの交換を促すことができる。 In the inner surface area, the excretion detection element 20 disposed in the outer area of the absorber 13 is in a state in which it can communicate with the reader / writer 31 that is an external device when not in contact with excrement. Therefore, the reader / writer 31 can read a signal from the excretion detection element 20. In this case, the reader / writer 31 can determine that urine has not leaked to the outer region of the absorber 13 in the inner surface region. On the other hand, when the excretion detection element 20 comes into contact with excretion, the excretion detection element 20 is in a state where communication is impossible. Therefore, the reader / writer 31 cannot read the signal from the excretion detection element 20. In this case, the reader / writer 31 determines that urine is leaking to the outer region of the absorber 13 in the inner surface region, and transmits a signal to the communication module 33 via the transmission unit 32. The communication module 33 is, for example, a smartphone or a controller. The communication module 33 can prompt the caregiver to replace the diaper 10 </ b> A by displaying diaper replacement or the like.
　次に、おむつ１０Ａの使用例について、図５を用いて説明する。図５は、おむつ１０Ａの交換フローチャートを示す。 Next, a usage example of the diaper 10A will be described with reference to FIG. FIG. 5 shows a replacement flowchart of the diaper 10A.
　図５に示すように、ステップＳＴ１１は、おむつ１０Ａの排泄検知素子２０と、リーダライタ３１とのペアリングを行う。ステップＳＴ１１では、おむつ１０Ａを識別するための設定を行う。 As shown in FIG. 5, in step ST11, the excretion detecting element 20 of the diaper 10A and the reader / writer 31 are paired. In step ST11, a setting for identifying the diaper 10A is performed.
　ステップＳＴ１２は、リーダライタ３１により排泄検知素子２０の信号を読み取る。ステップＳＴ１２では、リーダライタ３１により排泄検知素子２０が通信可能であることを確認する。 In step ST12, the reader / writer 31 reads the signal from the excretion detection element 20. In step ST12, the reader / writer 31 confirms that the excretion detection element 20 can communicate.
　ステップＳＴ１３は、前回のリーダライタ３１による読み取りから所定時間を経過している否かを判定する。所定時間とは、例えば、３０秒である。ステップＳＴ１３では、前回の読み取りから所定時間が経過している場合、フローはステップＳＴ１４へ進む。一方、前回の読み取りから所定時間が経過していない場合、フローを待機させて、再度ステップＳＴ１３を行う。 Step ST13 determines whether or not a predetermined time has elapsed since the previous reading by the reader / writer 31. The predetermined time is, for example, 30 seconds. In step ST13, when a predetermined time has passed since the previous reading, the flow proceeds to step ST14. On the other hand, if the predetermined time has not elapsed since the previous reading, the flow is waited and step ST13 is performed again.
　ステップＳＴ１４は、再度リーダライタ３１により排泄検知素子２０の信号を読み取る。ステップＳＴ１４では、リーダライタ３１により排泄検知素子２０の信号を読み取ることができるか否かを確認する。 In step ST14, the reader / writer 31 reads the signal from the excretion detecting element 20 again. In step ST14, it is confirmed whether the signal of the excretion detection element 20 can be read by the reader / writer 31.
　ステップＳＴ１５は、排泄検知素子２０が通信可能であるか否かを判定する。ステップＳＴ１５では、排泄検知素子２０が通信可能であると判定した場合、ステップＳＴ１３へ戻る。一方、排泄検知素子２０が通信不可能であると判定した場合、ステップＳＴ１６へ進む。 Step ST15 determines whether or not the excretion detection element 20 can communicate. In step ST15, when it is determined that the excretion detection element 20 can communicate, the process returns to step ST13. On the other hand, when it determines with the excretion detection element 20 being incommunicable, it progresses to step ST16.
　ステップＳＴ１６は、送信ユニット３２が通信モジュール３３へ信号を送信する。このステップＳＴ１６では、通信モジュール３３により介護者におむつ１０Ａの尿漏れを知らせることにより、介護者はおむつの交換を行うことができる。 In step ST16, the transmission unit 32 transmits a signal to the communication module 33. In step ST16, the caregiver can exchange the diaper by notifying the caregiver of the urine leakage of the diaper 10A by the communication module 33.
［効果］
　実施の形態１に係るおむつ１０Ａによれば、以下の効果を奏することができる。 [effect]
According to the diaper 10A according to Embodiment 1, the following effects can be achieved.
　実施の形態１に係るおむつ１０Ａは、おむつ１０Ａの内面領域において吸収体１３の外側領域に、排泄検知素子２０を配置することにより、吸収体１３から漏れた尿を検知することができる。したがって、おむつ１０Ａによれば、吸収体１３の尿の吸収限界を超えたことによる尿漏れや、おむつ１０Ａを正しく装着していないことによる尿漏れを素早く検知することができる。このように、おむつ１０Ａは、吸収体１３が尿の吸収限界を超えたこと、又はおむつ１０Ａが正しく装着されていないことによる尿漏れを検知することができる。 The diaper 10A according to Embodiment 1 can detect urine leaked from the absorber 13 by disposing the excretion detection element 20 in the outer region of the absorber 13 in the inner surface region of the diaper 10A. Therefore, according to the diaper 10A, it is possible to quickly detect urine leakage due to exceeding the urine absorption limit of the absorbent body 13 and urine leakage due to not wearing the diaper 10A correctly. Thus, the diaper 10A can detect urine leakage due to the absorber 13 exceeding the absorption limit of urine or the diaper 10A not being correctly worn.
　また、おむつ１０Ａでは、複数の排泄検知素子２０を腹側部分Ｌ１、股下部分Ｌ２、背側部分Ｌ３に配置しているため、おむつ使用者の状態に関わらず、吸収体１３の外側へ漏れた排泄物を検出することができる。例えば、おむつ１０Ａは、おむつ使用者が仰向けで寝ている状態、うつ伏せで寝ている状態、横向きに寝ている状態等の場合でも、尿漏れを検知することができる。 Moreover, in the diaper 10A, since the plurality of excretion detection elements 20 are arranged in the abdominal part L1, the crotch part L2, and the dorsal part L3, they leaked to the outside of the absorber 13 regardless of the state of the diaper user. Excrements can be detected. For example, the diaper 10 </ b> A can detect urine leakage even when the diaper user is sleeping on his / her back, lying on his / her face, sleeping on his / her side, or the like.
　また、おむつ１０Ａでは、吸収体１３に排泄検知素子２０を配置しない構成により、排泄を検知するためのみに使用される素子の数を減らし、コストを低減することができる。 Further, in the diaper 10A, the configuration in which the excretion detection element 20 is not disposed in the absorber 13 can reduce the number of elements used only for detecting excretion, thereby reducing the cost.
　本発明に係る実施の形態１のおむつ１０Ａを含むシステムによれば、おむつ１０Ａの尿吸収限界を超えたことによる尿漏れ、又はおむつ１０Ａを正しく装着していないことに寄る尿漏れが生じた場合に、介護者におむつ交換の必要があることを知らせることができる。したがって、おむつ１０Ａを含むシステムでは、おむつ交換の確認等の作業を減らすことができ、介護者の負担を減らすことができる。 According to the system including the diaper 10 </ b> A of the first embodiment according to the present invention, when urine leakage due to exceeding the urine absorption limit of the diaper 10 </ b> A or urinary leakage due to improper wearing of the diaper 10 </ b> A occurs. Can inform the caregiver that the diaper needs to be changed. Therefore, in the system including the diaper 10 </ b> A, it is possible to reduce work such as confirmation of diaper replacement and reduce the burden on the caregiver.
　なお、実施の形態１に係るおむつ１０Ａにおいては、腹側部分Ｌ１、股下部分Ｌ２、背側部分Ｌ３に４つの排泄検知素子２０を備える構成について説明したが、これに限定されない。おむつ１０Ａは、少なくとも１つ以上の排泄検知素子２０を、おむつ１０Ａの内面領域において、吸収体１３の外側領域に配置していればよい。例えば、おむつ１０Ａは、寝た状態でおむつ１０Ａを使用する場合、内面領域において、背側部分Ｌ３の吸収体１３の外側領域に１つの排泄検知素子２０を配置する構成であってもよい。また、排泄検知素子２０の数を４つより増やして、更に排泄物の検知精度を高めてもよい。このように、おむつ使用者の状態に応じて、排泄検知素子２０の数を増減させてもよい。また、排泄検知素子２０は、おむつ１０Ａの内面領域において吸収体１３の外側領域に配置されていればよく、配置位置は限定されない。 In the diaper 10A according to the first embodiment, the configuration including the four excretion detection elements 20 in the abdominal part L1, the crotch part L2, and the dorsal part L3 has been described, but the present invention is not limited thereto. The diaper 10A should just arrange | position the at least 1 or more excretion detection element 20 in the outer area | region of the absorber 13 in the inner surface area | region of 10 A of diapers. For example, when the diaper 10A is used in a lying state, the diaper 10A may have a configuration in which one excretion detection element 20 is disposed in the outer region of the absorber 13 of the back portion L3 in the inner surface region. In addition, the number of excretion detection elements 20 may be increased from four to further increase excretion detection accuracy. Thus, the number of excretion detection elements 20 may be increased or decreased according to the state of the diaper user. Moreover, the excretion detection element 20 should just be arrange | positioned in the outer area | region of the absorber 13 in the inner surface area | region of 10 A of diapers, and an arrangement position is not limited.
　また、おむつ１０Ａにおいては、内面領域において、ギャザー１４に対して吸収体１３が配置される側とは反対側に、排泄検知素子２０ａ、２０ｂを配置する構成について説明したが、これに限定されない。図６は、排泄検知素子２０ｅの配置例を示す図である。図６に示すように、おむつ１０Ａは、ギャザー１４の第１弾性部材１４ａと第２弾性部材１４ｂとの間に、排泄検知素子２０ｅを配置してもよい。このような構成により、吸収体１３の尿吸収限界を超えたことを検知すると共に、ギャザー１４の外側に尿が漏れる前に尿漏れを検知することができる。そのため、ギャザー１４の外側に尿漏れをする前に、介護者におむつ交換を知らせることができ、尿漏れによる汚染拡大を防止することができる。 Moreover, in the diaper 10A, although the structure which arrange | positions the excretion detection elements 20a and 20b in the inner surface area on the opposite side to the side where the absorber 13 is arrange | positioned with respect to the gathers 14 was demonstrated, it is not limited to this. FIG. 6 is a diagram illustrating an arrangement example of the excretion detection element 20e. As shown in FIG. 6, the diaper 10A may arrange | position the excretion detection element 20e between the 1st elastic member 14a of the gather 14, and the 2nd elastic member 14b. With such a configuration, it is possible to detect that the urine absorption limit of the absorber 13 has been exceeded and to detect urine leakage before urine leaks outside the gathers 14. Therefore, before the urine leaks outside the gather 14, the caregiver can be informed of the diaper replacement, and the increase in contamination due to the urine leak can be prevented.
　また、ギャザー１４は、内面シート１１上に、外面シート１２が配置される側とは反対側に突設した第１弾性部材１４ａ及び第２弾性部材１４ｂの２つを備える構成について説明したが、これに限定されない。例えば、ギャザー１４は、第１弾性部材１４ａのみを有する構成であってもよいし、３つ以上の弾性部材を並べて配置する構成であってもよい。ギャザー１４が３つ以上の弾性部材を並べて配置する構成を有する場合、排泄検知素子２０は、これらの複数の弾性部材の間にそれぞれ排泄検知素子２０を配置してもよい。 Moreover, although the gather 14 demonstrated the structure provided with two of the 1st elastic member 14a and the 2nd elastic member 14b which protruded on the opposite side to the side by which the outer surface sheet 12 is arrange | positioned on the inner surface sheet 11, It is not limited to this. For example, the gather 14 may have a configuration having only the first elastic member 14a, or may have a configuration in which three or more elastic members are arranged side by side. When the gather 14 has a configuration in which three or more elastic members are arranged side by side, the excretion detection element 20 may arrange the excretion detection elements 20 between the plurality of elastic members.
　また、排泄検知素子２０ａ、２０ｂは、ギャザー１４上に配置されているが、これに限定されない。排泄検知素子２０は、おむつ１０Ａの内面領域において、吸収体１３の外側領域に配置されていればよい。また、排泄検知素子２０ｃ、２０ｄは、内面シート１１上に配置されているが、これに限定されない。排泄検知素子２０は、内面シート１１の内側に配置されていてもよい。 Moreover, although the excretion detection elements 20a and 20b are arranged on the gather 14, they are not limited to this. The excretion detection element 20 should just be arrange | positioned in the outer area | region of the absorber 13 in the inner surface area | region of 10 A of diapers. Moreover, although the excretion detection elements 20c and 20d are arrange | positioned on the inner surface sheet 11, it is not limited to this. The excretion detection element 20 may be disposed inside the inner sheet 11.
　また、排泄検知素子２０は、尿との接触により通信不可能となる例を説明したが、これに限定されない例えば、排泄検知素子２０は、尿と接触せずに、素子の近傍にある尿を検知するものであってもよい。排泄検知素子２０は、リーダライタ３１から受信した電波又は磁界により電力を発生させて必要な処理を行った後、排泄検知素子２０内のデータを電波又は磁界に乗せてリーダライタ３１に返信している。そのため、排泄検知素子２０の近傍、即ち素子とリーダライタ３１との間のデータの返信経路に尿が存在すると、排泄検知素子２０からリーダライタ３１にデータが返信される際、排泄検知素子２０から発信される電力レベルが低下する。排泄検知素子２０は、電力レベルの低下を検知することによって、素子近傍にある尿を検知してもよい。また、排泄検知素子２０は、尿に接触することにより、通信可能となる素子であってもよい。 Moreover, although the excretion detection element 20 demonstrated the example which becomes unable to communicate by contact with urine, it is not limited to this, For example, the excretion detection element 20 does not contact urine, but the urine in the vicinity of an element It may be detected. The excretion detection element 20 generates electric power by the radio wave or magnetic field received from the reader / writer 31 and performs necessary processing. Then, the excretion detection element 20 returns the data in the excretion detection element 20 to the reader / writer 31 on the radio wave or magnetic field. Yes. Therefore, when urine is present in the vicinity of the excretion detection element 20, that is, in the data return path between the element and the reader / writer 31, when data is returned from the excretion detection element 20 to the reader / writer 31, the excretion detection element 20 The transmitted power level is reduced. The excretion detection element 20 may detect urine in the vicinity of the element by detecting a decrease in the power level. In addition, the excretion detection element 20 may be an element that can communicate by contacting urine.
　実施の形態１において、放射電極２３については、ダイポール型アンテナを説明したが、これに限定されない。例えば、放射電極２３は、モノポール型アンテナであってもよい。 In Embodiment 1, the dipole antenna has been described as the radiation electrode 23, but the present invention is not limited to this. For example, the radiation electrode 23 may be a monopole antenna.
　実施の形態１においては、リーダライタ３１が送信ユニット３２を用いて通信モジュール３３に信号を送信する構成について説明したが、これに限定されない。例えば、リーダライタ３１は、ハンディタイプのリーダライタであってもよい。介護者は、定期的に巡回してハンディタイプのリーダライタをおむつ１０Ａに当て、排泄検知素子２０を読み取ることによって、リーダライタと排泄検知素子２０との通信が可能か否かを検知してもよい。 In Embodiment 1, the configuration in which the reader / writer 31 transmits a signal to the communication module 33 using the transmission unit 32 has been described, but the present invention is not limited to this. For example, the reader / writer 31 may be a handy type reader / writer. The caregiver periodically visits the diaper 10 </ b> A with a handy type reader / writer and reads the excretion detection element 20 to detect whether the reader / writer can communicate with the excretion detection element 20. Good.
　ハンディタイプのリーダライタを用いたおむつ交換について、図７を用いて説明する。図７は、ハンディタイプのリーダライタを用いたおむつ交換のフローチャートを示す。 Diaper replacement using a handy type reader / writer will be described with reference to FIG. FIG. 7 shows a flowchart of changing diapers using a handy type reader / writer.
　図７に示すように、ステップＳＴ２１では、おむつ使用者がおむつ１０Ａを装着する。 As shown in FIG. 7, in step ST21, the diaper user wears the diaper 10A.
　ステップＳＴ２２では、おむつ交換の定期巡回時に、介護者がおむつ１０Ａにハンディタイプのリーダライタを当て、排泄検知素子２０の読み取りを行う。 In step ST22, the caregiver applies a handy reader / writer to the diaper 10A and reads the excretion detection element 20 during a regular tour of changing diapers.
　ステップＳＴ２３では、リーダライタと排泄検知素子２０との通信が可能か否かを判定する。ステップＳＴ１３では、リーダライタと排泄検知素子２０との通信が可能である場合、フローはステップＳＴ２４へ進む。一方、リーダライタと排泄検知素子２０との通信が不可能である場合、フローはステップＳＴ２５へ進む。 In step ST23, it is determined whether or not communication between the reader / writer and the excretion detection element 20 is possible. In step ST13, if communication between the reader / writer and the excretion detection element 20 is possible, the flow proceeds to step ST24. On the other hand, if communication between the reader / writer and the excretion detection element 20 is impossible, the flow proceeds to step ST25.
　ステップＳＴ２４では、リーダライタと排泄検知素子２０との通信が可能な状態であることから排泄が行われていないと判定できるため、介護者によるおむつ交換は行わず、フローがステップＳＴ２２に戻る。 In step ST24, since it is possible to determine that excretion has not been performed since communication between the reader / writer and the excretion detection element 20 is possible, the diaper is not changed by the caregiver, and the flow returns to step ST22.
　ステップＳＴ２５では、リーダライタと排泄検知素子２０との通信が不可能な状態であることから排泄が行われていると判定できるため、介護者によるおむつの除去を行う。 In step ST25, since it is possible to determine that excretion is being performed because communication between the reader / writer and the excretion detection element 20 is impossible, the diaper is removed by the caregiver.
　ステップＳＴ２６では、おむつ使用者が新しいおむつ１０Ａを装着する。 In step ST26, the diaper user wears a new diaper 10A.
　ステップＳＴ２７では、おむつ交換直後に、リーダライタによる排泄検知素子２０の読み取りを行い、フローはステップＳＴ２３に戻る。ステップＳＴ２７では、おむつ交換直後に、リーダライタによる排泄検知素子２０の読み取りを行うことにより、おむつ１０Ａの初期不良を検知することができる。なお、おむつ交換直後にリーダライタによる排泄検知素子２０の読み取りは、省略してもよい。この場合、ステップＳＴ２７を行わず、フローをステップＳＴ２２に戻してもよい。 In step ST27, immediately after changing the diaper, the excretion detecting element 20 is read by the reader / writer, and the flow returns to step ST23. In step ST27, immediately after exchanging the diaper, an initial failure of the diaper 10A can be detected by reading the excretion detecting element 20 with a reader / writer. In addition, you may abbreviate | omit reading of the excretion detection element 20 by a reader / writer immediately after diaper replacement | exchange. In this case, step ST27 may not be performed and the flow may be returned to step ST22.
　以上のように、介護者は、ハンディタイプのリーダライタを用いて、定期的に排泄が行われたか否かを確認し、おむつ交換を行うことができる。 As described above, a caregiver can check whether or not excretion has been performed regularly using a handy type reader / writer and change diapers.
（実施の形態２）
［全体構成］
　本発明に係る実施の形態２のおむつについて図８を用いて説明する。
　図８は、実施の形態２のおむつ１０Ｂを上から見た場合の概略構成を示す。図９は、図８に示すおむつ１０ＢのＢ－Ｂ線断面図を示す。なお、実施の形態２では、主に実施の形態１と異なる点について説明する。実施の形態２においては、実施の形態１と同一又は同等の構成については同じ符号を付して説明する。また、実施の形態２では、実施の形態１と重複する記載は省略する。 (Embodiment 2)
[overall structure]
The diaper of Embodiment 2 which concerns on this invention is demonstrated using FIG.
FIG. 8 shows a schematic configuration when the diaper 10B of the second embodiment is viewed from above. FIG. 9 shows a cross-sectional view of the diaper 10B shown in FIG. In the second embodiment, differences from the first embodiment will be mainly described. In the second embodiment, the same or equivalent components as those in the first embodiment will be described with the same reference numerals. In the second embodiment, descriptions overlapping with those in the first embodiment are omitted.
　図８及び図９に示すように、実施の形態２のおむつ１０Ｂは、実施の形態１のおむつ１０Ａと比べて、おむつ１０Ｂの内面領域において、ギャザー１４に対して吸収体１３が配置される側に、排泄検知素子２０ｆ、２０ｇを配置している点が異なる。 As shown in FIG.8 and FIG.9, the diaper 10B of Embodiment 2 is the side where the absorber 13 is arrange | positioned with respect to the gather 14 in the inner surface area | region of the diaper 10B compared with the diaper 10A of Embodiment 1. FIG. The difference is that the excretion detecting elements 20f and 20g are arranged.
　図８に示すように、排泄検知素子２０ｆ、２０ｇは、おむつ１０Ｂを上から見た場合に、吸収体１３の外縁に接触するように配置されている。また、図９に示すように、排泄検知素子２０ｆ、２０ｇは、ギャザー１４上であって、ギャザー１４の第１弾性部材１４ａと吸収体１３との間に配置されている。 As shown in FIG. 8, the excretion detection elements 20f and 20g are arranged so as to contact the outer edge of the absorber 13 when the diaper 10B is viewed from above. Further, as shown in FIG. 9, the excretion detection elements 20 f and 20 g are disposed on the gather 14 and between the first elastic member 14 a of the gather 14 and the absorber 13.
　排泄検知素子２０ｆ、２０ｇは、尿に一時的に接触して通信不可能になっても、その後に尿に接触しなくなった場合に通信が回復し、再び通信可能となる素子である。おむつ１０Ｂでは、内面領域においてギャザー１４に対して吸収体１３が配置される側に、排泄検知素子２０ｆ、２０ｇを配置している。そのため、排泄検知素子２０ｆと排泄検知素子２０ｇとのうちの少なくとも一方が、吸収体１３から漏れた尿と連続的に接触して通信不可能となった場合に、吸収体１３の尿の吸収限界に達していると検知することができる。 The excretion detection elements 20f and 20g are elements that can be communicated again when communication with the urine is temporarily lost and communication becomes impossible after that when the contact with the urine is lost. In the diaper 10B, the excretion detecting elements 20f and 20g are arranged on the side where the absorber 13 is arranged with respect to the gather 14 in the inner surface area. Therefore, when at least one of the excretion detection element 20f and the excretion detection element 20g continuously contacts the urine leaked from the absorber 13 and communication becomes impossible, the urine absorption limit of the absorber 13 becomes impossible. Can be detected.
　おむつ１０Ｂの使用限界を検知するメカニズムについて、図１０～１３を用いて詳細に説明する。なお、以下のメカニズムの説明は、排泄検知素子２０ｆに着目して説明する。 The mechanism for detecting the usage limit of the diaper 10B will be described in detail with reference to FIGS. The following explanation of the mechanism will be made focusing on the excretion detection element 20f.
　図１０は、おむつ使用者がおむつ１０Ｂを装着した状態であって、排泄を行う前の状態を示す。図１０に示すように、おむつ１０Ｂの装着状態では、ギャザー１４の第１弾性部材１４ａ及び第２弾性部材１４ｂが、おむつ使用者のからだ１００を包むことにより、尿がおむつ１０Ｂの外側へ漏れることを防止している。おむつ使用者のからだ１００の下方に吸収体１３が配置されている。排泄検知素子２０ｇ、２０ｆは、おむつ１０Ｂの内面領域において、吸収体１３の外側領域であって、ギャザー１４の第１弾性部材１４ａの近くに配置されている。 FIG. 10 shows a state where the diaper user is wearing the diaper 10B and before excretion. As shown in FIG. 10, when the diaper 10 </ b> B is attached, the first elastic member 14 a and the second elastic member 14 b of the gather 14 wrap the body 100 of the diaper user, so that urine leaks outside the diaper 10 </ b> B. Is preventing. Absorber 13 is arranged below body 100 of the diaper user. The excretion detection elements 20g and 20f are disposed outside the absorber 13 and in the vicinity of the first elastic member 14a of the gather 14 in the inner surface region of the diaper 10B.
　図１１は、排尿時のおむつ１０Ｂの状態を示す。図１１に示すように、排尿時におむつ使用者のからだ１００から尿１１０が内面領域に排出されると、尿１１０が内面シート１１上を流れ、排泄検知素子２０ｆに接触する。このとき、排泄検知素子２０ｆは、尿１１０と接触するため、一時的に通信不可能になる。 FIG. 11 shows the state of the diaper 10B during urination. As shown in FIG. 11, when urine 110 is discharged from the diaper user's body 100 to the inner surface area during urination, the urine 110 flows on the inner surface sheet 11 and contacts the excretion detecting element 20f. At this time, since the excretion detection element 20f comes into contact with the urine 110, communication temporarily becomes impossible.
　図１２は、吸収体１３が尿１１０を吸収したおむつ１０Ｂの状態を示す。図１２中の矢印１１１は、内面シート１１を透過して吸収体１３に吸収される尿１１０の移動方向を示す。図１２に示すように、吸収体１３が尿１１０を吸収すると、排泄検知素子２０ｆは、尿と接触しなくなる。そのため、排泄検知素子２０ｆは、通信が回復し、リーダライタ３１等の外部装置と通信可能になる。 FIG. 12 shows a state of the diaper 10 </ b> B in which the absorber 13 has absorbed the urine 110. An arrow 111 in FIG. 12 indicates the moving direction of the urine 110 that passes through the inner surface sheet 11 and is absorbed by the absorber 13. As shown in FIG. 12, when the absorber 13 absorbs urine 110, the excretion detection element 20f does not come into contact with urine. Therefore, the excretion detection element 20f recovers communication and can communicate with an external device such as the reader / writer 31.
　図１３は、吸収体１３が尿吸収限界を超えたときのおむつ１０Ｂの状態を示す。図１３に示すように、吸収体１３で吸収しきれなくなった尿１１０は、吸収体１３上に溜まっていく。吸収体１３上に溜まった尿１１０は、連続的に排泄検知素子２０ｆと接触した状態となり、排泄検知素子２０ｆの通信が不可能な状態が続く。したがって、おむつ１０Ｂでは、排泄検知素子２０ｆが通信不可能になった状態が続いた場合に、吸収体１３の尿吸収限界に達していると判定することができる。 FIG. 13 shows the state of the diaper 10B when the absorber 13 exceeds the urine absorption limit. As shown in FIG. 13, the urine 110 that cannot be absorbed by the absorber 13 accumulates on the absorber 13. The urine 110 collected on the absorber 13 is continuously in contact with the excretion detection element 20f, and the excretion detection element 20f is unable to communicate. Therefore, in the diaper 10B, it can be determined that the urine absorption limit of the absorbent body 13 has been reached when the excretion detection element 20f continues to be unable to communicate.
［効果］
　実施の形態２に係るおむつ１０Ｂによれば、以下の効果を奏することができる。 [effect]
According to the diaper 10B according to Embodiment 2, the following effects can be achieved.
　実施の形態２に係るおむつ１０Ｂは、おむつ１０Ｂの内面領域において、ギャザー１４に対して吸収体１３が配置される側に、排泄検知素子２０ｆ、２０ｇを配置している。このような構成により、排泄検知素子２０ｆ、２０ｇにおいて、尿検知状態、即ち通信不可能な状態が続いた場合に、吸収体１３が尿吸収限界に達していることを外部装置等により判定することができる。このように、おむつ１０Ｂによれば、おむつ１０Ｂの尿吸収限界を検知することができるため、介護者によるおむつ交換の頻度を低減することができ、介護者の負担を軽減すると共に、おむつの消費を低減することができる。 In the diaper 10B according to Embodiment 2, the excretion detection elements 20f and 20g are arranged on the side where the absorber 13 is arranged with respect to the gather 14 in the inner surface area of the diaper 10B. With such a configuration, when the urine detection state, that is, the communication impossible state continues in the excretion detection elements 20f and 20g, it is determined by an external device or the like that the absorber 13 has reached the urine absorption limit. Can do. Thus, according to the diaper 10B, since the urine absorption limit of the diaper 10B can be detected, the frequency of changing diapers by the caregiver can be reduced, the burden on the caregiver can be reduced, and consumption of the diaper can be reduced. Can be reduced.
　おむつ１０Ｂにおいて、内面領域において吸収体１３の外側領域に排泄検知素子２０を配置する構成による効果を説明するため、以下の実験を行った。 In the diaper 10B, the following experiment was performed in order to explain the effect of the configuration in which the excretion detection element 20 is arranged in the outer region of the absorber 13 in the inner surface region.
　実験は、内面領域において吸収体１３の外側領域に排泄検知素子２０を配置する場合（実施例１）と、内面領域において吸収体１３の内側領域に排泄検知素子２０を配置する場合（比較例１）と、を比較した。 In the experiment, when the excretion detection element 20 is arranged in the outer region of the absorber 13 in the inner surface region (Example 1), and when the excretion detection element 20 is arranged in the inner region of the absorber 13 in the inner surface region (Comparative Example 1). ) And.
　まず、比較例１について説明する。
　比較例１では、吸収体１３の内側領域に配置された排泄検知素子２０に対し、１００ｃｃの尿を接触させた。尿との接触直後に、排泄検知素子２０とリーダライタ３１とが通信不可能な状態となり、１０分後においても通信不可能な状態であった。吸収体１３の内側領域に排泄検知素子２０を配置した場合、排泄検知素子２０は、吸収体１３の内側領域に吸収された尿に接触した状態が続く。そのため、比較例１では、排泄検知素子２０は、１回でも排泄が行われると、通信不可能な状態となり、通信が回復することはなかった。 First, Comparative Example 1 will be described.
In Comparative Example 1, 100 cc of urine was brought into contact with the excretion detection element 20 disposed in the inner region of the absorber 13. Immediately after contact with urine, the excretion detection element 20 and the reader / writer 31 became unable to communicate, and even after 10 minutes, communication was impossible. When the excretion detection element 20 is disposed in the inner region of the absorber 13, the excretion detection element 20 continues to be in contact with urine absorbed in the inner region of the absorber 13. Therefore, in the comparative example 1, when the excretion detecting element 20 is excreted even once, the excretion detection element 20 becomes unable to communicate, and communication is not recovered.
　次に、実施例１について説明する。
　実施例１では、吸収体１３の外側領域に配置された排泄検知素子２０に対し、１００ｃｃの尿を接触させた。尿との接触直後に、排泄検知素子２０とリーダライタ３１とが通信不可能な状態となったが、５秒後に通信可能な状態に回復した。吸収体１３の外側領域に排泄検知素子２０を配置した場合、排尿時には吸収体１３の外側領域にも尿が流れるため、排泄検知素子２０に尿が接触し、排泄検知素子２０とリーダライタ３１との通信が一時的に不可能となる。しかし、時間が経過すると、吸収体１３の外側領域に流れた尿が吸収体１３に吸収され、尿が排泄検知素子２０と接触しなくなる。このため、実施例１では、排尿時には排泄検知素子２０とリーダライタ３１との通信が一時的に不可能な状態になるが、時間の経過と共に通信が回復した。 Next, Example 1 will be described.
In Example 1, 100 cc of urine was brought into contact with the excretion detection element 20 arranged in the outer region of the absorber 13. Immediately after contact with the urine, the excretion detection element 20 and the reader / writer 31 become unable to communicate with each other, but recovered to a state where they can communicate after 5 seconds. When the excretion detection element 20 is disposed in the outer region of the absorber 13, since urine flows also in the outer region of the absorber 13 during urination, the urine contacts the excretion detection element 20, and the excretion detection element 20, the reader / writer 31, Communication temporarily becomes impossible. However, after a lapse of time, urine that has flowed to the outer region of the absorber 13 is absorbed by the absorber 13 and the urine does not come into contact with the excretion detection element 20. For this reason, in Example 1, although the excretion detection element 20 and the reader / writer 31 are temporarily unable to communicate during urination, the communication is recovered over time.
　比較例１及び実施例１の結果からわかるように、吸収体１３の外側領域に排泄検知素子２０を配置した場合、尿が吸収体１３の吸収限界を超えて吸収体１３の外側領域に漏れ出すまで、排泄検知素子２０は、リーダライタ３１と通信することができる。したがって、実施の形態２のおむつ１０Ｂは、吸収体１３の外側領域に排泄検知素子２０を配置することによって、吸収体１３の尿吸収限界を検知することができるという優れた効果を有している。 As can be seen from the results of Comparative Example 1 and Example 1, when the excretion detection element 20 is arranged in the outer region of the absorber 13, urine leaks out of the absorber 13 beyond the absorption limit of the absorber 13. Until now, the excretion detection element 20 can communicate with the reader / writer 31. Therefore, the diaper 10 </ b> B of the second embodiment has an excellent effect that the urine absorption limit of the absorber 13 can be detected by disposing the excretion detection element 20 in the outer region of the absorber 13. .
