Description

本発明は、被介護者又は乳幼児等の排泄又は放屁検知対象者の排泄又は放屁を検知する排泄又は放屁検知器に関し、特に、排泄又は放屁検知対象者の衣服・おむつ等への着脱が容易に行えるポータブルタイプの排泄又は放屁検知器に関する。 The present invention relates to an excretion or flatulence detector that detects excretion or flatulence of a person to be cared for or an infant or the like, and in particular, can be easily attached to and detached from clothes, diapers, etc. of the person to be detected by excretion or flatulence. Concerning portable type excretion or flatulence detectors that can be performed.

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 the 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 that does not come into contact with the excrement of the absorbent article, and detects the impedance change between the pair of electrodes formed side by side slightly apart from one surface of the hard substrate by the sensor means. The presence or absence of excretion in the absorbent article is confirmed based on the change in frequency according to the 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 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 the conventional gas sensor, and moreover, it is smaller and consumes less power than the conventional gas sensor.

May be 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 flatulence detector 10 can wirelessly communicate with the other device 20. The other device 20 is, for example, a mobile phone carried by a caregiver or a caregiver, a smartphone, a mobile tablet, a computer installed inside or outside the care center, or the like. There are no restrictions on the means of communication with the other device 20. Short-range wireless communication line by Bluetooth (registered trademark), power-saving wide area line by 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 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 flatulence detector 10 has a CPU board 16. The CPU board 16 is a control means 17 composed of a CPU having a calculation function, a working RAM, a ROM for storing various data and programs, and a unique identification number or a unique identification number assigned to each excretion or release detector 10. A signal receiving means 19 as an input interface including a storage means 18 for storing identification information peculiar to the excretion or release detector 10 such as an identification code, an amplification unit, an A / D conversion unit, and the like, and inputting a detection signal from the gas sensor element 12. For example, the communication means 13 for transmitting the excretion or release information to the other device 20 via the various communication lines described above is provided. The components are connected to each other 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 flatulence based on the excretion or flatulence detection program stored in the ROM or the like based on the detection signal from the gas sensor element 12. Then, when there is excretion or flatulence, the excretion or flatulence information for notifying that there is excretion or flatulence is generated. Then, the generated excretion or flatulence information is transmitted to the other device 20 via the communication means 13. At this time, the control means 17 transmits the excretion or flatulence information to the other device 20 together with the identification information stored in the storage means 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 care facility is the detection target person, all the caregivers wear the excretion or flatulence detector 10 respectively. The excretion or flatulence detector 10 is provided with unique identification information for identifying each excretion or flatulence detector 10, which is different identification information for each excretion or flatulence detector 10. Then, when the caregiver wears the excretion or release detector 10, the caregiver information showing information about the caregiver (for example, name, gender, room number, etc.) and the identification information of the excretion or release detector 10 to be worn are used. Is associated and stored in the caregiver information storage means (not shown). The caregiver information storage means is provided, for example, in another computer or server (not shown), an external storage medium, or the like. The other device 20 is configured to be accessible to the caregiver information storage means. Further, the caregiver information storage means may be provided in the other 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 device 20 receives the excretion or flatulence information, it refers to the caregiver information storage means and is based on the caregiver information associated with the identification information received together with the excretion or flatulence information. Therefore, it is possible to determine which excretion or flatulence detector 10 is the excretion or flatulence information, that is, which caregiver is the excretion or flatulence information.

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良い。 The excretion or flatulence detection program executed by the control means 17 may use a conventionally known excretion or flatulence 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 flatulence information indicating urination is generated, and the detection signal is predetermined. If it is within the second threshold range, it is determined that there is defecation, and excretion or flatulence information indicating defecation is generated. Alternatively, when the detection signal is within a predetermined third threshold range, it is determined that there is flatulence, and excretion or flatulence information indicating flatulence is generated. Further, the presence or absence of excretion or flatulence may be determined according to the change in the signal strength of the detection signal received from the gas sensor element 12. Further, the excretion detection method described in Japanese Patent No. 6184631 by the applicant of the present application may be used.

図５は、排泄又は放屁検知器１０の使用状態の一例を示す説明図である。
検知対象者は、例えば、被介護者、乳幼児等である。排泄又は放屁検知器１０は、検知対象者が着用するズボン等の着衣に、筐体１１外部に備えたフック１４を引っ掛けて掛着し使用する。そして、検知対象者の排泄物（便、尿）又は放屁から発生するガスを、ガス導入孔１５から筐体１１内部に取り込み、ガスセンサ素子１２により検知する。
排泄又は放屁検知器１０の筐体１１は、縦方向サイズが６０ｍｍ以下、横方向サイズが３０ｍｍ以下、厚さ方向サイズが１０ｍｍであり、非常に小型である。そのため、装着しているときにも殆ど異物感を感じることはない。また、フック１４を引っ掛けるだけで装着できるので、着替えの際等、排泄又は放屁検知器１０の着脱を容易に行うことができる。 FIG. 5 is an explanatory diagram showing an example of a usage state of the excretion or flatulence detector 10.
The detection target is, for example, a care recipient, an infant, or the like. The excretion or flatulence detector 10 is used by hooking a hook 14 provided on the outside of the housing 11 on clothes such as trousers worn by a detection target person. Then, the gas generated from the excrement (feces, urine) or flatulence of the detection target person is taken into the inside of the housing 11 through the gas introduction hole 15, and is detected by the gas sensor element 12.
The housing 11 of the excretion or flatulence detector 10 has a vertical size of 60 mm or less, a horizontal size of 30 mm or less, and a thickness direction size of 10 mm, and is very small. Therefore, even when wearing it, there is almost no feeling of foreign matter. Further, since it can be attached only by hooking the hook 14, it is possible to easily attach / detach the excretion or flatulence detector 10 when changing clothes.

他の例による排泄又は放屁検知器５０は、図６乃至図８に示すように、筐体１１とガス導入孔１５の形状が上述した実施形態の排泄又は放屁検知器１０（図１）と異なる。排泄又は放屁検知器５０は、排泄又は放屁検知器１０に比べて、さらに小型化されており、その筐体１１のサイズは、縦方向サイズが３０ｍｍ以下、横方向サイズが１５ｍｍ以下、厚さ方向サイズが１０ｍｍ以下である。図７に示すように、排泄又は放屁検知器５０は、筐体１１背面に、検知対象者が着用する吸収性物品又は着衣に貼着するための粘着テープ又は面ファスナー３０を備える。なお、排泄又は放屁検知器５０が備えるガスセンサ素子１２、ガス導入孔１５、通信手段１３・制御手段１７・記憶手段１８・信号受信手段１９を含むＣＰＵ基板１６、の構成及び機能は上述した実施形態と同様であるため説明を省略する。 As shown in FIGS. 6 to 8, the excretion or flatulence detector 50 according to another example has different shapes of the housing 11 and the gas introduction hole 15 from the excretion or flatulence detector 10 (FIG. 1) of the above-described embodiment. .. The excretion or flatulence detector 50 is further miniaturized as compared with the excretion or flatulence detector 10, and the size of the housing 11 is 30 mm or less in the vertical direction, 15 mm or less in the horizontal direction, and the thickness direction. The size is 10 mm or less. As shown in FIG. 7, the excretion or flatulence detector 50 is provided with an adhesive tape or a hook-and-loop fastener 30 on the back surface of the housing 11 for being attached to an absorbent article or clothing worn by a detection target person. The configuration and function of the CPU board 16 including the gas sensor element 12, the gas introduction hole 15, the communication means 13, the control means 17, the storage means 18, and the signal receiving means 19 included in the excretion or flatulence detector 50 are the above-described embodiments. Since it is the same as the above, the description thereof will be omitted.

図８は、筐体１１に備えた粘着テープにより排泄又は放屁検知器５０をおむつに貼りつけた場合の使用例である。
筐体１１に面ファスナーを備えて、排泄又は放屁検知器５０を面ファスナーにより着衣（例えばズボン）等に貼着する場合には、雄雌いずれか一方の面ファスナーにより構成し、検知対象者の着衣の側にそれと対になる雄雌いずれか他方の面ファスナーを縫い付け又は貼り付け等により備える。着衣自体を他方の面ファスナー材により構成してもよい。 FIG. 8 is an example of use in the case where the excretion or flatulence detector 50 is attached to the diaper by the adhesive tape provided on the housing 11.
When the housing 11 is provided with a hook-and-loop fastener and the excretion or release detector 50 is attached to clothing (for example, trousers) by the hook-and-loop fastener, the housing 11 is composed of either male or female hook-and-loop fastener, and the detection target person has a hook-and-loop fastener. A pair of male and female hook-and-loop fasteners are sewn or attached to the side of the garment. The clothing itself may be made of the other hook-and-loop fastener material.

特に、多数のループからなる雌の面ファスナーのほうが、多数のカギ状体からなる雄のファスナーよりも柔らかく肌触りがよいため、衣服に具備するのに好適である。従って、雌の面ファスナーを着衣の側に備えることが好ましい。そして、雌の面ファスナー材を着衣に備えた場合には、筐体１１には、対となる雄の面ファスナーを備える。 In particular, a female hook-and-loop fastener consisting of a large number of loops is softer and softer than a male fastener consisting of a large number of key-like bodies, and is therefore suitable for wearing on clothes. Therefore, it is preferable to provide a female hook-and-loop fastener on the side of the clothes. When the female hook-and-loop fastener material is provided on the clothes, the housing 11 is provided with a pair of male hook-and-loop fasteners.

以上説明したように、排泄又は放屁検知器１０、５０によれば、縦方向サイズが６０ｍｍ以下、横方向サイズが３０ｍｍ以下、厚さ方向サイズが１０ｍｍ以下に構成された筐体１１内にガスセンサ素子１２を具備し、検知信号に基づく排泄又は放屁情報を他の装置２０へ送信する通信手段１３、及び、筐体１１外部に着脱手段としてフック１４又は粘着テープ又は面ファスナー３０を備え、かつ、排泄物又は放屁から発生するガスを導入するガス導入孔１５を筐体１１に備えたので、排泄又は放屁検知の性能を維持したまま、排泄又は放屁検知対象者の衣服・おむつ等への着脱を手軽に行うことができ、かつ、小型でポータブルな排泄又は放屁検知器を実現することができる。 As described above, according to the excretion or flatulence detectors 10 and 50, the gas sensor element is contained in the housing 11 having a vertical size of 60 mm or less, a horizontal size of 30 mm or less, and a thickness direction size of 10 mm or less. A communication means 13 for transmitting excretion or flatulence information based on a detection signal to another device 20, and a hook 14 or an adhesive tape or a surface fastener 30 as an attachment / detachment means outside the housing 11 and excretion. Since the housing 11 is provided with a gas introduction hole 15 for introducing gas generated from an object or flatulence, it is easy to put on and take off the clothes, diapers, etc. of the person subject to excretion or flatulence detection while maintaining the performance of excretion or flatulence detection. It is possible to realize a small and portable excretion or flatulence detector.
