　おむつ内の排泄の有無をセンサで検知する検知装置がある。例えば、特許文献１に記載された排泄確認装置がある。この排泄確認装置は、吸収性物品の排泄物に接しない外側表面に取り付けられ、固い基板の一方の面に僅かに離して並べて形成された一対の電極間のインピーダンス変化をセンサ手段で検知し、センサ手段で検知された一対の電極間のインピーダンス変化に応じた周波数の変化に基づいて吸収性物品内の排泄の有無を確認するものである。
　一方で、近年、超小型のセンサが開発されている。例えば、Ｓｉ基板の空洞部上に設けたブリッジあるいはダイアフラムに、金属酸化物半導体膜とヒータとを設けた、ＭＥＭＳ（メムス、Micro Electro Mechanical Systems）構造のガスセンサが開発されている（特許文献２）。このようなＭＥＭＳタイプのガスセンサは従来のガスセンサに比べて性能に劣るところはなく、しかも、従来のガスセンサに比べて小型化、低消費電力化が実現されている。 There is a detection device that detects the presence or absence of excretion in a diaper with a sensor. For example, there is an excretion confirmation device described in Patent Document 1. This excretion confirmation device is attached to the outer surface of the absorbent article that does not come into contact with excrement, and detects a change in impedance between a pair of electrodes formed side by side on the one surface of the hard substrate by being slightly separated from each other by sensor means. The presence or absence of excretion in the absorbent article is confirmed based on a change in frequency according to a change in impedance between the pair of electrodes detected by the sensor means.
On the other hand, in recent years, ultra-small sensors have been developed. For example, a gas sensor having a MEMS (Micro Electro Mechanical Systems) structure in which a metal oxide semiconductor film and a heater are provided on a bridge or a diaphragm provided on a cavity of a Si substrate has been developed (Patent Document 2). . Such a MEMS type gas sensor is not inferior in performance to a conventional gas sensor, and furthermore, is smaller and consumes less power than a conventional gas sensor.

A communication unit 13 that transmits the excretion or flatulence detector 10 together with the unique identification information for identifying the excretion or flatulence detector 10 to the detection target person. Hook 14 as an attaching / detaching means. The casing 11 is provided with a gas introduction hole 15 for introducing excrement or gas generated from flatus from the outside of the casing 11 to the gas sensor element 12.
　排泄又は放屁検知器１０の筐体１１は、樹脂等の絶縁材料により構成されている。筐体１１内には、ガスセンサ素子１２、通信手段１３を含むＣＰＵ基板１６、電源を供給する電池（不図示）を備える。また、筐体１１には、ガスセンサ素子１２に筐体１１の外部からガスを導入するガス導入孔１５が設けられている。 筐 体 The casing 11 of the excretion or flatus detector 10 is made of an insulating material such as resin. The housing 11 includes a gas sensor element 12, a CPU board 16 including a communication unit 13, and a battery (not shown) for supplying power. The housing 11 is provided with a gas introduction hole 15 for introducing gas into the gas sensor element 12 from outside the housing 11.
　ガスセンサ素子１２は、超小型のセンサ素子を用いる。例えば、市販されている数ｍｍ程度のサイズの、ＭＥＭＳ構造により形成されたガスセンサ素子を利用する。例えば、ＭＥＭＳタイプ半導体式ガスセンサTGS8100（フィガロ技研）を用いる。
　また、ＣＰＵ基板１６も四方のサイズが数ｍｍ～十数ｍｍ程度である。
　このような超小型のガスセンサ素子１２及びＣＰＵ基板１６により、筐体１１の小型化を実現できる。 As the gas sensor element 12, an ultra-small sensor element is used. For example, a commercially available gas sensor element having a size of about several mm and having a MEMS structure is used. For example, a MEMS type semiconductor gas sensor TGS8100 (Figaro Giken) is used.
Further, the size of the CPU substrate 16 on all sides is about several mm to about several tens mm.
With such an ultra-small gas sensor element 12 and CPU board 16, the size of the housing 11 can be reduced.
　本実施形態における排泄又は放屁検知器１０には、複数のガス導入孔１５が設けられており、排泄物（便、尿）又は体外に放出された腸内ガスである屁から発生するガスを筐体１１内に導入する。各ガス導入孔１５の面積は、それぞれ約３ｍｍ＾２～６ｍｍ＾２程度である。なお、本実施形態では、ガス導入孔１５を複数設けたが、ガスセンサ素子１２による検知信号の出力値にノイズ等の悪影響がない場合には、中央部に大きな１つのガス導入孔１５を設けてもよい。 The excretion or flatus detector 10 according to the present embodiment is provided with a plurality of gas introduction holes 15 for housing gas generated from flat excrement (feces, urine) or intestinal gas discharged outside the body. It is introduced into the body 11. The area of each gas introduction hole 15 is about 3 mm ＾ 2 to 6 mm ＾ 2. In the present embodiment, a plurality of gas introduction holes 15 are provided. However, when there is no adverse effect such as noise on the output value of the detection signal by the gas sensor element 12, one large gas introduction hole 15 is provided at the center. Is also good.
　排泄又は放屁検知器１０は、他の装置２０と無線で通信可能である。他の装置２０とは、例えば、介護者、保育者が携帯する携帯電話、スマートフォン、携帯タブレット、介護センター内外に設置されたコンピュータ等である。他の装置２０との通信手段に制限はない。ブルートゥース（登録商標）による近距離無線通信回線、ＬＰＷＡ（Low Power Wide Area）による省電力広域回線、３Ｇ／４Ｇ／５Ｇなどのセルラー回線、無線ＬＡＮ（Local Area Network）回線、ＮＦＣ（Near Field Communication）超近距離無線通信回線等が通信手段の一例である。 The excretion or flatus detector 10 can wirelessly communicate with another device 20. The other device 20 is, for example, a mobile phone, a smart phone, a mobile tablet, a computer installed inside or outside the care center, or the like, carried by a caregiver or a caregiver. There is no limitation on the means of communication with another device 20. Short-range wireless communication line using Bluetooth (registered trademark), low-power wide-area line using LPWA (Low Power Wide Area), cellular line such as 3G / 4G / 5G, wireless LAN (Local Area Network) line, NFC (Near Field Communication) An ultra-short-range wireless communication line or the like is an example of the communication means.
　排泄又は放屁検知器１０は、ＣＰＵ基板１６を有する。ＣＰＵ基板１６は、演算機能を有するＣＰＵ、作業用ＲＡＭ、各種データ及びプログラムを記憶するＲＯＭ等から構成された制御手段１７、各排泄又は放屁検知器１０に割り当てられた固有の識別番号又は固有の識別コード等、排泄又は放屁検知器１０固有の識別情報を記憶する記憶手段１８、増幅部及びＡ／Ｄ変換部等を備えガスセンサ素子１２からの検知信号を入力する入力インターフェースとしての信号受信手段１９、例えば上述した各種通信回線を介して他の装置２０に排泄又は放屁情報を送信する通信手段１３、を備えて構成されている。各構成部材はバスを介して相互に接続されている。 The excretion or flatus detector 10 has a CPU board 16. The CPU board 16 includes a CPU having an arithmetic function, a working RAM, a control means 17 including a ROM for storing various data and programs, a unique identification number assigned to each excretion or flatus detector 10, or a unique identification number. A storage unit 18 for storing identification information such as an identification code and the like, which is unique to the excretion or flatus detector 10, a signal receiving unit 19 provided with an amplification unit, an A / D conversion unit, and the like, as an input interface for inputting a detection signal from the gas sensor element 12. For example, the communication device 13 includes communication means 13 for transmitting excretion or flatus information to the other device 20 via the various communication lines described above. Each component is interconnected via a bus.
　制御手段１７は、ガスセンサ素子１２からの検知信号に基づいて、ＲＯＭ等に記憶する排泄又は放屁検知プログラムに基づいて排泄又は放屁の有無を判定する。そして、排泄又は放屁があった場合には、排泄又は放屁があったことを知らせるための排泄又は放屁情報を生成する。そして、生成した排泄又は放屁情報を通信手段１３を介して他の装置２０へ送信する。このとき、制御手段１７は、排泄又は放屁情報を、記憶手段１８に記憶されている識別情報と共に他の装置２０へ送信する。 The control means 17 determines the presence or absence of excretion or flatus, based on the detection signal from the gas sensor element 12 and based on the excretion or flatus detection program stored in the ROM or the like. If there is excretion or flatus, excretion or flatus information for notifying that excretion or flatus has occurred is generated. Then, the generated excretion or flatus information is transmitted to another device 20 via the communication unit 13. At this time, the control unit 17 transmits the excretion or flatus information to the other device 20 together with the identification information stored in the storage unit 18.
　例えば、介護施設内の介護者が検知対象者である場合、介護者全員がそれぞれ排泄又は放屁検知器１０を装着する。排泄又は放屁検知器１０には、排泄又は放屁検知器１０毎に異なる識別情報であって、各排泄又は放屁検知器１０を識別するための固有の識別情報が付与されている。そして、介護者が排泄又は放屁検知器１０を装着する際、介護者に関する情報（例えば、氏名、性別、部屋番号等）を示す介護者情報と、装着する排泄又は放屁検知器１０の識別情報とを対応づけて介護者情報記憶手段（不図示）に記憶する。介護者情報記憶手段は、例えば、他のコンピュータ又はサーバ（不図示）、又は、外部記憶媒体等に設ける。他の装置２０は、介護者情報記憶手段にアクセス可能に構成されている。また、他の装置２０内に介護者情報記憶手段を具備してもよい。 For example, when the caregiver in the nursing home is the detection target, all the caregivers wear the excretion or flatus detector 10, respectively. The excretion or flatulence detector 10 is provided with identification information that is different for each excretion or flatulence detector 10 and that is unique for identifying each excretion or flatulence detector 10. When the caregiver wears the excretion or flatulence detector 10, the caregiver information indicating information about the caregiver (for example, name, gender, room number, and the like), and the identification information of the mounted excretion or flatulence detector 10 Is stored in the caregiver information storage means (not shown) in association with the caregiver information. The caregiver information storage means is provided in, for example, another computer or server (not shown) or an external storage medium. The other device 20 is configured to be able to access the caregiver information storage means. Further, a caregiver information storage unit may be provided in another device 20.
　このような構成のため、他の装置２０では、排泄又は放屁情報を受信すると、介護者情報記憶手段を参照して、排泄又は放屁情報と共に受信した識別情報に対応付けられた介護者情報に基づいて、どの排泄又は放屁検知器１０からの排泄又は放屁情報であるか、すなわち、どの介護者からの排泄又は放屁情報であるかを判別することができる。 Due to such a configuration, when the other apparatus 20 receives the excretion or flatus information, the other apparatus 20 refers to the caregiver information storage unit and based on the caregiver information associated with the identification information received together with the excretion or flatus information. Thus, it is possible to determine which excretion or flatus information from the excretion or flatus detector 10, that is, which excretion or flatus information from the caregiver.
　なお、制御手段１７により実行される排泄又は放屁検知プログラムは従来公知の排泄又は放屁検知プログラムを利用すればよい。例えば、排泄判定閾値を設け、ガスセンサ素子１２から受信した検知信号が所定の第一閾値範囲に在る場合に排尿があるとして判定し排尿を示す排泄又は放屁情報を生成し、検知信号が所定の第二閾値範囲に在る場合に排便があるとして判定し排便を示す排泄又は放屁情報を生成する。或いは、検知信号が所定の第三閾値範囲に在る場合に、放屁があるとして判定し放屁を示す排泄又は放屁情報を生成する等である。また、ガスセンサ素子１２から受信した検知信号の信号強度の変化に応じて排泄又は放屁の有無を判定してもよい。また、本願出願人による特許第6184631号に記載の排泄検知手法を利用してもよい。 The excretion or flatus detection program executed by the control means 17 may use a conventionally known excretion or flatus detection program. For example, an excretion determination threshold is provided, and when the detection signal received from the gas sensor element 12 is within a predetermined first threshold range, it is determined that there is urination, and excretion or flatus information indicating urination is generated. When it is within the second threshold range, it is determined that there is bowel movement, and excretion or flatus information indicating bowel movement is generated. Alternatively, when the detection signal is within a predetermined third threshold range, it is determined that there is flatus, and excretion or flatus information indicating flatus is generated. Further, the presence or absence of excretion or flatus may be determined according to a change in the signal intensity of the detection signal received from the gas sensor element 12. Further, the excretion detection method described in Japanese Patent No. 6186431 by the present applicant may be used.
