Operation unit (for example, keyboard etc.) 22 that gives an instruction signal to the control unit 21, CCD controller unit 23 that controls CCD 12b of IR camera 12 of excretion confirmation device 10 through operation unit 22, electricity from IR camera 12 an input unit 24 as an input interface for inputting an electric signal from the IR camera 12 into the inside of the display device 20, which includes an amplification unit for amplifying a signal and an A/D conversion unit for converting the output of the amplification unit from analog to digital; , a communication unit 25 that exchanges various electrical signals with the excretion confirmation device 10, such as a control signal to the CCD 12b and an electrical signal from the IR camera 12, and a display monitor that displays the input captured image by the IR camera 12. and a display unit 26 having a display screen. Each component is interconnected via a bus. A general-purpose personal computer, for example, can be used as the display device 20 .
図５は、排泄確認装置１０の使用状態の説明図である。
排泄確認装置１０を、被介護者の股間に接触させる。排泄確認装置１０を接触させた状態でＩＲ－ＬＥＤ照明器１１により赤外線を含む光をおむつに照射させる。そして、排泄確認装置１０を接触させた状態でＩＲ用カメラ１２にて撮像する。
なお、赤外線は、可視光線よりも波長が長く、直進性が高い。そのため、おむつ表面を透過することができる。一方で、「排泄物（例えば、便）」、或いは、「排泄物（例えば、尿）を吸収したおむつの吸収材」には、赤外線が吸収される。このような赤外線の特性を利用することにより、排泄の有無がわかるＩＲ画像として取得することができる。
FIG. 5 is an explanatory diagram of the state of use of the excretion confirmation device 10. As shown in FIG.
The excretion confirmation device 10 is brought into contact with the care-receiver's crotch. The IR-LED illuminator 11 irradiates the diaper with light including infrared rays while the excretion confirmation device 10 is in contact with the diaper. Then, an image is captured by the IR camera 12 while the excretion confirmation device 10 is in contact.
Infrared rays have a longer wavelength than visible rays and have a higher linearity. Therefore, it can permeate the diaper surface. On the other hand, "excretion (for example, feces)" or "absorbent material of a diaper that has absorbed excrement (for example, urine)" absorbs infrared rays. By utilizing such infrared characteristics, it is possible to obtain an IR image that indicates the presence or absence of excretion.
図６は排泄がない場合に表示装置２０に表示されるＩＲ画像の表示例であり、図７は、排泄がある場合に表示装置２０に表示されるＩＲ画像の表示例である。
おむつ内部に「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」がない場合には、おむつの外側から、ＩＲ‐ＬＥＤ照明器１１により照射された赤外線を吸収する「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」がないために、ＩＲ用カメラ１２には何も映らない（図６）。
FIG. 6 is a display example of an IR image displayed on the display device 20 when there is no excretion, and FIG. 7 is a display example of an IR image displayed on the display device 20 when there is excretion.
When there is no "excretion (e.g., feces)" or "diaper absorbent material that has absorbed excrement (e.g., urine)" inside the diaper, the IR-LED illuminator 11 emits light from the outside of the diaper. Since there is no "excretion (for example, feces)" or "absorption material of the diaper that absorbs the excrement (for example, urine)" that absorbs infrared rays, nothing is captured by the IR camera 12 (FIG. 6).
そして、おむつ内部に「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」がある場合には、ＩＲ‐ＬＥＤ照明器１１により照射された赤外線が、当該「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」によって吸収されながら反射し、ＩＲ用カメラ１２に入射されるため、黒く影が映る（図７）。 Then, when there is "excretion (for example, feces)" or "absorbent material of the diaper that has absorbed excrement (for example, urine)" inside the diaper, the infrared rays emitted by the IR-LED illuminator 11 The light is reflected while being absorbed by the “excretion (eg, feces)” or “absorbent material of the diaper that has absorbed the excrement (eg, urine)”, and is incident on the IR camera 12, resulting in a black shadow (Fig. 7).
このように、「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」の有無が確認できるのである。
以上説明したように、本実施形態の排泄確認装置１０によれば、介護者等のおむつ交換を行う者が、おむつを開ける前に、排泄の有無を確認できる。さらに、本実施形態の排泄確認装置１０は、図１、図２、図３、図５等に示す如く、主要部材はＩＲ‐ＬＥＤ照明器１１とＩＲ用カメラ１２を備えるのみである。そのため、介護者等のおむつ交換を行う者が、片手で把持可能な程度まで小型化することが可能である。
In this way, it is possible to confirm the presence or absence of "excretion (eg, feces)" or "absorbent material of a diaper that has absorbed excrement (eg, urine)".
As described above, according to the excretion confirmation device 10 of the present embodiment, a person who changes diapers, such as a caregiver, can confirm the presence or absence of excretion before opening the diaper. Furthermore, as shown in FIGS. 1, 2, 3, 5, etc., the excretion confirmation device 10 of the present embodiment only includes an IR-LED illuminator 11 and an IR camera 12 as main members. Therefore, it is possible to reduce the size to such an extent that it can be held with one hand by a person who changes diapers, such as a caregiver.
なお、排泄確認装置１０の感度は、ＩＲ－ＬＥＤ照明器１１により照射される赤外線を含む光の強度、具体的には赤外帯域の光の強度に依存する。また、排泄確認装置１０の感度は、ＩＲ用カメラ１２に使用されるＩＲセンサの感度にも依存する。例えば、ＩＲ－ＬＥＤ照明器１１により照射される赤外線を含む光の強度が高い場合、或いは、ＩＲ用カメラ１２に使用されるＩＲセンサの感度が高い場合には、おむつの表面のみならず、被介護者が着用する衣服も透過する場合がある。この場合には、衣服の上から排泄確認装置１０を接触させて排泄の有無を確認可能になるため、確認のために衣服を脱衣させる作業が不要となり、介護者及び被介護者の双方の負担がより少なくなる。 The sensitivity of the excretion confirmation device 10 depends on the intensity of the light including infrared rays emitted from the IR-LED illuminator 11, specifically the intensity of light in the infrared band. Moreover, the sensitivity of the excretion confirmation device 10 also depends on the sensitivity of the IR sensor used in the IR camera 12 . For example, when the intensity of light including infrared rays emitted by the IR-LED illuminator 11 is high, or when the sensitivity of the IR sensor used in the IR camera 12 is high, not only the surface of the diaper but also the surface Clothing worn by caregivers may also be permeable. In this case, since it is possible to confirm the presence or absence of excretion by touching the excretion confirmation device 10 over the clothes, it is not necessary to remove the clothes for confirmation, which is a burden on both the caregiver and the cared person. becomes less.
一方で、排泄確認装置１０の感度が高すぎると、衣服もおむつも透過してしまい、被介護者の股間が写る場合がある。そうなると、被介護者の精神的負担が高まり好ましくない。従って、赤外線の強度及びＩＲセンサの感度は、ＩＲ画像において、おむつ内の「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」が影の如く確認できる程度に調整することが好ましい。 On the other hand, if the sensitivity of the excretion confirmation device 10 is too high, clothes and diapers may be seen through, and the crotch area of the care-receiver may be photographed. In this case, the mental burden on the cared person increases, which is not preferable. Therefore, the intensity of the infrared rays and the sensitivity of the IR sensor can be confirmed in the IR image as if the "excretion (e.g., feces)" in the diaper or the "absorbent material of the diaper that absorbed the excrement (e.g., urine)" is seen as a shadow. It is preferable to adjust as much as possible.
さらに、本実施形態では、排泄確認装置１０を、被介護者の股間に接触させ、当該接触させた状態でＩＲ－ＬＥＤ照明器１１による光の照射、及び、ＩＲ用カメラ１２による撮影を行なう例について説明したが、排泄確認装置１０の感度が高い場合には、おむつ内の「排泄物（例えば、便）」又は「排泄物（例えば、尿）を吸収したおむつの吸収材」が影の如く確認できる範囲で、排泄確認装置１０を被介護者の股間から僅かに離して使用してもよい。例えば、数ミリメートル程度離して使用してもよい。 Furthermore, in the present embodiment, the excretion confirmation device 10 is brought into contact with the care recipient's crotch, and in this contact state, the IR-LED illuminator 11 emits light, and the IR camera 12 takes an image. However, when the sensitivity of the excretion confirmation device 10 is high, the "excretion (eg, feces)" in the diaper or the "absorbent material of the diaper that has absorbed the excrement (eg, urine)" appears like a shadow. The excretion confirmation device 10 may be used slightly away from the care-receiver's crotch as long as it can be confirmed. For example, they may be used separated by several millimeters.
さらに、排泄確認装置１０は、吸収性物品（例えば、おむつ又は尿取りパッド）と撮像手段（ＩＲ用カメラ１２）との間に配設されて可視光を遮断すると共に赤外線を通過させる赤外線フィルタを備えてもよい。すなわち、排泄確認装置１０は、おむつから反射されたＩＲ‐ＬＥＤ照明器１１からの光の可視光（例えば７２０ｎｍ）以下の波長の光をカットし赤外帯域の光のみＩＲ用カメラ１２に入射させるＩＲフィルタ１５（赤外線フィルタ）を備えても良い。図８は、ＩＲフィルタ１５を備える排泄確認装置１０の外観説明図である。 Furthermore, the excretion confirmation device 10 includes an infrared filter that is disposed between an absorbent article (for example, a diaper or a urine absorbing pad) and an imaging means (IR camera 12) to block visible light and pass infrared light. You may prepare. That is, the excretion confirmation device 10 cuts light with a wavelength of visible light (for example, 720 nm) or less from the light from the IR-LED illuminator 11 reflected from the diaper, and allows only light in the infrared band to enter the IR camera 12. An IR filter 15 (infrared filter) may be provided. FIG. 8 is an external explanatory view of the excretion confirmation device 10 having the IR filter 15. As shown in FIG.
排泄確認装置１０は、被介護者が寝ている布団内に、介護者等のおむつ交換を行う者が、排泄確認装置１０を入れて、被介護者の股間におむつ又は着衣及びおむつの上から接触させて使用することを使用状態の一例として想定している。このように、暗い布団内で排泄確認装置１０を使用する場合、或いは、夜間巡回の際に暗闇で排泄確認装置１０を使用する場合には、ＩＲフィルタ１５を備えなくともよい。一方、昼間又は照明光下、布団外部で使用する場合など、可視光が赤外線の強度に影響を与える場合には、おむつ又は着衣及びおむつを履いた被介護者とＩＲ用カメラ１２との間にＩＲフィルタ１５を配設して可視光を遮断し、赤外線を通過させるＩＲフィルタ１５を備えることが好ましい。 The excretion confirmation device 10 is placed in the futon on which the care recipient is sleeping, and a caregiver or other person who changes diapers puts the excretion confirmation device 10 between the crotch of the care recipient and puts it on the diaper or clothes and the diaper. It is assumed that it is used in contact as an example of the state of use. Thus, when using the excretion confirmation device 10 in a dark futon, or when using the excretion confirmation device 10 in the dark during night patrols, the IR filter 15 may not be provided. On the other hand, when visible light affects the intensity of the infrared rays, such as when used in the daytime, under illumination, or outside a futon, the infrared camera 12 should be placed between the care receiver wearing diapers or clothes and diapers and the IR camera 12 . It is preferable to provide an IR filter 15 to block visible light and pass infrared light.

The present invention is not limited to this, and for example, an IR camera 12 using other methods such as CMOS (Complementary Metal Oxide Semiconductor) may be used.
さらに、本実施形態では、ＩＲ‐ＬＥＤ照明器１１は、電源差込口１４に接続された電源コードを介して商用電源から電力を得たが、表示装置２０から電力を得ても良い。この場合、例えば、表示装置２０のＵＳＢポート等を介して、表示装置２０に排泄確認装置１０を接続して排泄確認装置１０内部に備えたＩＲ‐ＬＥＤ照明器１１に電力を供給する。 Furthermore, in the present embodiment, the IR-LED illuminator 11 obtains power from a commercial power source through the power cord connected to the power outlet 14, but may also obtain power from the display device 20. FIG. In this case, for example, the excretion confirmation device 10 is connected to the display device 20 via a USB port or the like of the display device 20 to supply power to the IR-LED illuminator 11 provided inside the excretion confirmation device 10 .
本発明の適用範囲は上述した実施形態に限定されることはない。本発明は、介護者等のおむつ交換を行う者が、おむつを開ける前に排泄の有無を確認できる排泄確認装置及び排泄確認方法に対し、広く適用することができる。 The scope of application of the present invention is not limited to the embodiments described above. INDUSTRIAL APPLICABILITY The present invention can be widely applied to an excretion confirmation device and an excretion confirmation method that enable a person who changes diapers, such as a caregiver, to confirm the presence or absence of excretion before opening the diaper.
