Each component is connected to each other via a bus. As the display device 20, for example, a general-purpose personal computer can be used.
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 usage state of the excretion confirmation device 10.
The excretion confirmation apparatus 10 is brought into contact with the care receiver's crotch. The diaper is irradiated with light including infrared rays by the IR-LED illuminator 11 in a state where the excretion confirmation device 10 is in contact. Then, an image is taken by the IR camera 12 with the excretion confirmation device 10 in contact.
Infrared light has a longer wavelength than visible light and has high straightness. Therefore, it can permeate the diaper surface. On the other hand, infrared rays are absorbed by “excrement (for example, stool)” or “diaper absorbent material that has absorbed excrement (for example, urine)”. By utilizing such infrared characteristics, it can be acquired as 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）。
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 “excrement (for example, stool)” or “absorbent for absorbing excrement (for example, urine)” inside the diaper, the IR-LED illuminator 11 irradiates from the outside of the diaper. Since there is no “excrement (for example, stool)” or “diaper absorbing material for excrement (for example, urine)” that absorbs infrared rays, nothing is reflected on 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）。 And, when there is “excrement (for example, stool)” or “diaper absorbing material for excrement (for example, urine)” inside the diaper, the infrared rays irradiated by the IR-LED illuminator 11 are Reflected while being absorbed by the “excrement (for example, stool)” or “absorbent of diaper that has absorbed excrement (for example, urine)” and is incident on the IR camera 12, a shadow appears in black (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。
Thus, the presence or absence of “excrement (for example, stool)” or “absorbent of diaper that has absorbed excrement (for example, urine)” can be confirmed.
As described above, according to the excretion confirmation device 10 of the present embodiment, a person performing exchanging diapers such as a caregiver can confirm the presence or absence of excretion before opening the diaper. Furthermore, the excretion confirmation apparatus 10 of the present embodiment includes only an IR-LED illuminator 11 and an IR camera 12, as shown in FIGS. 1, 2, 3, 5, and the like. Therefore, it is possible to reduce the size to such an extent that a person who changes diapers such as a caregiver can hold the diaper with one hand.
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。 In addition, the sensitivity of the excretion confirmation apparatus 10 depends on the intensity of light including infrared rays irradiated by 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 irradiated 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 covered surface. Clothes worn by caregivers may also be transmitted. In this case, since it is possible to confirm the presence or absence of excretion by contacting the excretion confirmation device 10 from above the clothes, it is not necessary to take off the clothes for confirmation, and both the caregiver and the care recipient are burdened. Is 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, both the clothes and the diaper may pass through, and the care receiver's crotch may be reflected. If this happens, the mental burden on the cared person increases, which is not preferable. Therefore, the infrared intensity and the sensitivity of the IR sensor are confirmed in the IR image as if “excretion (for example, stool)” or “diaper absorbing material for excretion (eg, urine)” in the diaper is shaded. It is preferable to adjust to the extent 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 receiver's crotch, and light irradiation by the IR-LED illuminator 11 and photographing by the IR camera 12 are performed in the contacted state. In the case where the sensitivity of the excretion confirmation device 10 is high, the “excrement (for example, stool)” or the “diaper absorbent material that has absorbed the excrement (for example, urine)” in the diaper is shaded. As long as it can be confirmed, the excretion confirmation device 10 may be used slightly separated from the care receiver's crotch. For example, you may use about several millimeters apart.
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。 Further, the excretion confirmation device 10 is provided between an absorbent article (for example, a diaper or a urine collecting pad) and an imaging means (IR camera 12), and has an infrared filter that blocks visible light and transmits infrared light. You may prepare. In other words, the excretion confirmation device 10 cuts light having a wavelength less than or equal to visible light (for example, 720 nm) of light from the IR-LED illuminator 11 reflected from the diaper, and allows only infrared light to enter the IR camera 12. An IR filter 15 (infrared filter) may be provided. FIG. 8 is an explanatory diagram of the appearance of the excretion confirmation apparatus 10 including the IR filter 15.
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 provided by a person who replaces a diaper such as a caregiver in a futon where the caregiver is sleeping and puts the excretion confirmation device 10 between the diaper or clothes and the diaper of the caregiver. It is assumed as an example of the use state that it is used in contact. Thus, when using the excretion confirmation apparatus 10 in a dark futon, or when using the excretion confirmation apparatus 10 in the dark during patrol at night, the IR filter 15 may not be provided. On the other hand, when visible light affects the intensity of infrared rays, such as when used outside the futon in the daytime or under illumination, between the caregiver wearing the diaper or clothes and diapers and the IR camera 12 It is preferable to provide an IR filter 15 that disposes an IR filter 15 to block visible light and allow infrared rays to pass.
