排便時に併発するガス（以下排泄ガスと呼ぶ）を検出し、その検出結果に基づいて、人間の健康状態を判断する技術が知られている。例えば、特許文献１には、ガスセンサを用いて放屁に含まれる有臭ガスを検出し、そのガスセンサからの信号値を直接或いは匂い分析などの適当な処理を行って表示することが開示されている。また、例えば、特許文献２には、脱臭体に吸着された臭気成分を酸化させてその酸化電流から臭気成分濃度を測定する技術が開示されている。  2. Description of the Related Art There is known a technique for detecting a gas (hereinafter referred to as excretion gas) that occurs at the time of defecation and determining a human health state based on the detection result. For example, Patent Document 1 discloses that a gas sensor is used to detect odorous gas contained in the release, and a signal value from the gas sensor is displayed directly or by performing appropriate processing such as odor analysis. . For example, Patent Document 2 discloses a technique for oxidizing an odor component adsorbed on a deodorizing body and measuring the odor component concentration from the oxidation current.

特許文献３は、腸内状態報知装置およびその方法に関する本出願人の発明である。この装置では、排泄ガス中の水素ガスをガスセンサで測定し、ガスセンサから出力された信号値に対応した腸内状態情報を腸内健康度判定用付属情報から抽出してユーザに報知するものである。腸内状態情報としては、腸内に存在する種々の菌の総数、ビフィズス菌の数、悪玉菌の数、腸内菌の総数のうちのビフィズス菌数の割合、又は、腸内菌の総数のうちの悪玉菌数の割合等を採用している。   Patent Document 3 is the applicant's invention relating to an intestinal state notification device and method.

ところで、腸内状態を正確に推定するにはターゲットとするガス成分を精度良く測定することが重要である。特に有臭ガス、例えば硫化水素を測定して腸内状態を推定する場合、数ｐｐｍレベルの濃度を正確に測定することが求められる。硫化水素センサの例として定電位電解型センサと半導体型センサが挙げられ、中でも半導体型センサは長寿命で安価との利点がある。
しかし、これらの硫化水素センサはターゲット成分に対する特異性が低い難点がある。例えば硫化水素センサが水素に対しても一定の応答を示すが、排便ガスの中には水素ガスの濃度レベルが硫化水素の数十倍、場合には数千倍に達するので、そのまま使用しても硫化水素の濃度を推測することができないという問題がある。 By the way, in order to accurately estimate the intestinal state, it is important to accurately measure the target gas component. In particular, when an intestinal state is estimated by measuring odorous gas such as hydrogen sulfide, it is required to accurately measure a concentration of several ppm level. Examples of hydrogen sulfide sensors include a constant potential electrolytic sensor and a semiconductor sensor. Among them, a semiconductor sensor has advantages such as long life and low cost.
However, these hydrogen sulfide sensors have a drawback of low specificity to the target component. For example, a hydrogen sulfide sensor shows a certain response to hydrogen, but in the defecation gas, the hydrogen gas concentration level is several tens of times higher than that of hydrogen sulfide, and in some cases several thousand times higher. However, there is a problem that the concentration of hydrogen sulfide cannot be estimated.

以下に添付図面に基づいて本発明の実施形態を具体的に説明する。まず第一の実施例を図１から図２に基いて説明する。 Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. First, a first embodiment will be described with reference to FIGS.

図１は、本発明の健康状態測定装置を搭載した人体洗浄装置組込タイプ洋式便器の一例を示す（部分透視）外観図である。 FIG. 1 is an external view (partial perspective view) showing an example of a Western-style toilet with a built-in human body cleaning device equipped with the health condition measuring device of the present invention.

便器１の便座２と便鉢３周縁の頂部との間に設けたスペースを利用して脱臭ファン用排気通路４が設置されている。脱臭ファン用排気通路４内には、脱臭ファン５、およびふたつのガスセンサからなるガスセンサ７が取り付けられている。 The exhaust passage 4 for a deodorizing fan is installed using the space provided between the toilet seat 2 of the toilet bowl 1 and the top of the toilet bowl 3 periphery. A deodorizing fan 5 and a gas sensor 7 including two gas sensors are attached in the exhaust passage 4 for the deodorizing fan.

また、制御部８および演算部９は一体化して便座２の後部内に組み込まれ、さらに、制御部８により算出された結果である腸内状態指標データの表示部１０が、人体洗浄装置の操作パネル１１に組み込まれている。ガスセンサ７と演算部９とのデータ交換は結線により、また制御部８と表示部１０とのデータ交換は赤外線により行っている。なお、演算部９はガス濃度を演算する演算機能の外に、データ記憶部およびガスセンサ７を制御するガスセンサ制御部を備えている。また、制御部８は得られた硫化水素濃度を含めた測定結果から腸内状態指標に変換する機能を担う。 In addition, the control unit 8 and the calculation unit 9 are integrated and incorporated in the rear part of the toilet seat 2, and the display unit 10 of intestinal state index data, which is a result calculated by the control unit 8, operates the human body washing apparatus. It is incorporated in the panel 11.

Further, the control unit 8 has a function of converting the obtained measurement result including the hydrogen sulfide concentration into an intestinal state index.

図２は本発明の健康状態測定装置の第１実施例を示す概念図である。脱臭ファン用排気通路４内に、風上側から順に脱臭ファン５、ガスセンサ２１、ガスセンサ２２が配置されている。 FIG. 2 is a conceptual diagram showing a first embodiment of the health condition measuring apparatus of the present invention. A deodorizing fan 5, a gas sensor 21, and a gas sensor 22 are arranged in this order from the windward side in the exhaust passage 4 for the deodorizing fan.

演算部９が測定開始信号を同時にガスセンサ２１とガスセンサ２２に送信し両ガスセンサが作動し始めると、センサに接するガスのガス濃度に応じた出力信号が得られる。ガスセンサ２１とガスセンサ２２で得られたセンサ出力信号が演算部９に送られ、時系列的に記憶される。また、演算部９の測定終了信号によって両ガスセンサの作動が終了し、センサ出力の信号の記録が終了する。続いて、演算部９では後述の方法にしたがって記憶されたセンサの出力信号からガス濃度を求め、その結果を制御部８に送信し、そこで腸内状態指標を推算し、得られた腸内状態指標が表示部１０で表示される。
次に本実施例の演算部９による硫化水素濃度の算出について詳細に説明する。
ガスセンサ２１とガスセンサ２２はそれぞれ硫化水素に対する第１応答特性および共存ガス（本実施例では水素）に対する第２応答特性を有する。図３はガス濃度とセンサの出力信号との関係から両センサの応答特性に示す概念図である。センサの出力信号はガス濃度と直線的な関係になるように加工されている。図示のように、ガスセンサ２１は傾きがα１となる硫化水素に対する第１応答特性、および傾きがβ１となる共存ガスの水素に対する第２応答特性を示す。一方、ガスセンサ２２も傾きがα２となる硫化水素に対する第１応答特性、および傾きがβ２となる共存ガスの水素に対する第２応答特性を示す。ガスセンサ２１とガスセンサ２２の出力をそれぞれV1とV2とし、硫化水素濃度および水素濃度をそれぞれ[H2S] と[H2]とすると、出力とガス濃度との間に以下の関係が成り立つ。
V1＝α１[H2S]＋β１[H2] 式１
V2＝α２[H2S]＋β２[H2] 式２
式１と式２から、硫化水素濃度[H2S]が以下の式により求まる：
[H2S]＝(V1β２−V2β１)/(α１β２−α2β１) 式３
式３から、ガスセンサ２１とガスセンサ２２の第１応答特性と第２応答特性を用いて、センサの出力から硫化水素の濃度を算出することができる。
以下硫化水素濃度を演算する演算部９の動作に基いて本実施例における硫化水素濃度の測定をさらに説明する。
演算部９は第１演算部と第２演算部を含む。演算部９の第一演算部では前述通り記憶された測定開始から測定終了までのガスセンサ２１とガスセンサ２２の出力信号データから、それぞれ出力信号の最大値Vp1およびVp2を探し出す。次に、出力信号の最大値Vp1およびVp2をそのままの値、またはそれぞれのガスセンサの最小出力をベースとした相対値をそれぞれガスセンサ２１およびガスセンサ２２の出力V1およびV2とする。第２演算部では、ガスセンサ２１とガスセンサ２２の第一応答特性（図３または式３のα１、α２）および第２応答特性（図３または式３のβ１、β２）から導いたセンサ出力から硫化水素濃度へ変換する変換表が予め記憶されており、第１演算部で得られたセンサ出力から、記憶されているセンサ出力を硫化水素濃度への変換表を用いて、センサの出力信号に対応する硫化水素濃度を算出する。
以上本発明の第一実施例について説明した。本実施例ではガスセンサ２１とガスセンサ２２の第１応答特性どうしおよび第２応答特性どうしがともに異なっているが、両特性どうしのどちらか一方が異なるだけでもよい。例えば、第１応答特性どうしが異なり、第２応答特性どうしが同じである場合、式３が次のようになり、第１応答特性のみ用いて硫化水素の濃度を算出することができる。
[H2S]＝(V1−V2)/(α１−α２) 式４）
また、センサの設置場所に関しても、本実施例ではガスセンサ２１とガスセンサ２２は脱臭ファン用排気通路内に設置しているが、両センサに接する排泄ガスの濃度が実質的に同じであることが担保されれば、他の場所、例えばトイレ装置の便鉢部や便座周辺に設置してもよい。 When the calculation unit 9 simultaneously transmits a measurement start signal to the gas sensor 21 and the gas sensor 22 and both gas sensors start to operate, an output signal corresponding to the gas concentration of the gas in contact with the sensor is obtained. Sensor output signals obtained by the gas sensor 21 and the gas sensor 22 are sent to the calculation unit 9 and stored in time series. Further, the operation of both gas sensors is ended by the measurement end signal of the calculation unit 9, and the recording of the sensor output signal is ended. Subsequently, the calculation unit 9 obtains the gas concentration from the sensor output signal stored in accordance with the method described later, and transmits the result to the control unit 8, where the intestinal state index is estimated, and the obtained intestinal state is obtained. The indicator is displayed on the display unit 10.
Next, calculation of the hydrogen sulfide concentration by the calculation unit 9 of the present embodiment will be described in detail.
Each of the gas sensor 21 and the gas sensor 22 has a first response characteristic for hydrogen sulfide and a second response characteristic for a coexisting gas (hydrogen in this embodiment). FIG. 3 is a conceptual diagram showing response characteristics of both sensors from the relationship between the gas concentration and the output signal of the sensor. The output signal of the sensor is processed so as to have a linear relationship with the gas concentration. As shown in the figure, the gas sensor 21 exhibits a first response characteristic with respect to hydrogen sulfide having an inclination of α 1 and a second response characteristic with respect to hydrogen of the coexisting gas having an inclination of β 1 . On the other hand, the gas sensor 22 also exhibits a first response characteristic for hydrogen sulfide having an inclination of α 2 and a second response characteristic for hydrogen of a coexisting gas having an inclination of β 2 . When the outputs of the gas sensor 21 and the gas sensor 22 are V 1 and V 2 , and the hydrogen sulfide concentration and the hydrogen concentration are [H 2 S] and [H 2 ], respectively, the following relationship is established between the output and the gas concentration: .
V 1 = α 1 [H 2 S] + β 1 [H 2 ] Equation 1
V 2 = α 2 [H 2 S] + β 2 [H 2 ] Equation 2
From Equation 1 and Equation 2, the hydrogen sulfide concentration [H 2 S] is determined by the following equation:
[H 2 S] = (V 1 β 2 −V 2 β 1 ) / (α 1 β 2 −α 2 β 1 ) Equation 3
From Equation 3, the concentration of hydrogen sulfide can be calculated from the output of the sensor using the first response characteristic and the second response characteristic of the gas sensor 21 and the gas sensor 22.
Hereinafter, the measurement of the hydrogen sulfide concentration in the present embodiment will be further described based on the operation of the calculation unit 9 for calculating the hydrogen sulfide concentration.
The calculation unit 9 includes a first calculation unit and a second calculation unit. The first calculation unit of the calculation unit 9 searches for the maximum values Vp1 and Vp2 of the output signals from the output signal data of the gas sensor 21 and the gas sensor 22 from the measurement start to the measurement end stored as described above. Then, as it is the value maximum value Vp1 and Vp2 of the output signal, or based on the minimum output of each gas sensor to the relative value and the output V 1 and V 2, respectively the gas sensor 21 and the gas sensor 22. In the 2nd calculating part, it derived from the 1st response characteristic ((alpha) 1 , (alpha) 2 of FIG. 3 or Formula 3) and the 2nd response characteristic ((beta) 1 , (beta) 2 of FIG. 3 or Formula 3) of the gas sensor 21 and the gas sensor 22. A conversion table for converting the sensor output to the hydrogen sulfide concentration is stored in advance, and the sensor output stored in the first calculation unit is used to convert the stored sensor output to the hydrogen sulfide concentration. The hydrogen sulfide concentration corresponding to the output signal is calculated.
The first embodiment of the present invention has been described above. In this embodiment, the first response characteristic and the second response characteristic of the gas sensor 21 and the gas sensor 22 are different from each other, but either one of the two characteristics may be different. For example, when the first response characteristics are different and the second response characteristics are the same, Equation 3 becomes as follows, and the concentration of hydrogen sulfide can be calculated using only the first response characteristics.
[H 2 S] = (V 1 −V 2 ) / (α 1 −α 2 ) Equation 4)
Further, regarding the sensor installation location, in this embodiment, the gas sensor 21 and the gas sensor 22 are installed in the exhaust passage for the deodorizing fan, but it is ensured that the concentration of excretion gas in contact with both sensors is substantially the same. If it is done, you may install in other places, for example, the toilet bowl part and toilet seat periphery of a toilet apparatus.

FIG. 4 is a conceptual diagram showing a second embodiment of the health condition measuring apparatus of the present invention. A deodorizing fan 5, a first gas sensor 24, a deodorizing cartridge 23 that is a hydrogen sulfide removing unit, and a second gas sensor 25 are disposed in the deodorizing fan exhaust passage 4 in order from the upstream side of the gas flow.

演算部９が測定開始信号を同時に第１ガスセンサ２４と第２ガスセンサ２５に送信し両ガスセンサが作動し始めると、センサに接するガスのガス濃度に応じた出力信号が得られる。ガスセンサ２１とガスセンサ２２で得られたセンサ出力信号が演算部９に送られ、時系列的に記憶される。また、演算部９の測定終了信号によって両ガスセンサの作動が終了し、センサ出力の信号の記録が終了する。続いて、演算部９では後述の方法にしたがって記憶されたセンサの出力信号からガス濃度を求め、その結果を制御部８に送信し、そこで腸内状態指標を推算し、得られた腸内状態指標が表示部１０で表示される。
本実施例において、硫化水素除去部の上流側に配置されている第１ガスセンサ２４は硫化水素に対する第１応答特性および共存ガス（本実施例では水素）に対する第２応答特性を有する。また、硫化水素除去部の下流側に配置されている第２ガスセンサ２５は共存ガス（本実施例では水素）に対する第２応答特性を有する。図５はガス濃度とセンサの出力信号との関係から両センサの応答特性に示す概念図である。センサの出力信号はガス濃度と直線的な関係になるように加工されている。図示するように、第１ガスセンサ２４は傾きがα１となる硫化水素に対する第１応答特性、および傾きがβ１となる共存ガスの水素に対する第２応答特性を有する。一方、第２ガスセンサ２５は傾きがβ２となる共存ガスの水素に対する第２応答特性を有する。第一ガスセンサ２４と第２ガスセンサ２５の出力をそれぞれV1とV2とし、硫化水素濃度および水素濃度をそれぞれ[H2S] と[H2]とすると、出力とガス濃度との間に以下の関係が成り立つ。
V1＝α１[H2S]＋β１[H2] 式５
V2＝ β２[H2] 式６
硫化水素除去部によって硫化水素が除去されているので、式６に示すように、第２ガスセンサ２５の出力に硫化水素による寄与が含まれていない。式５と式６から、硫化水素濃度[H2S]が以下の式により求まる：
[H2S]＝(V1β２−V2β１)/α１β２ 式７
硫化水素濃度を演算する演算部９は第１の実施例と同様に、第１演算部と第２演算部を含む。第１演算部では第１実施例と同様な動作で、第１ガスセンサ２４および第２ガスセンサ２５の出力V1およびV2を求める。第２演算部では、第１ガスセンサ２４第１応答特性（図５または式７のα１）および第１ガスセンサ２４と第２ガスセンサ２５の第２応答特性（図５または式７のβ１、β２）から導いたセンサ出力から硫化水素濃度へ変換する変換表が予め記憶されており、第１演算部で得られたセンサ出力V1およびV2から、記憶されているセンサ出力を硫化水素濃度への変換表を用いて、センサの出力信号に対応する硫化水素濃度を算出する。
以上本発明の第２実施例について説明した。続いて本発明の第３の実施例について説明する。
図６は本発明の健康状態測定装置の第３実施例を示す概念図である。本実施例の装置構成は図４に示す第２実施例と同様であるが、硫化水素除去部２３の上流側に配置されている第１ガスセンサ２６と硫化水素除去部２３の下流側に配置されている第２ガスセンサ２７が共存ガス（本実施例では水素）に対して同一の第２応答特性を有する点で異なる。図７はガス濃度とセンサの出力信号との関係から両センサの応答特性に示す概念図である。センサの出力信号はガス濃度と直線的な関係になるように加工されている。図示するように、第１ガスセンサ２６と第２ガスセンサ２７は共に傾きがβとなる共存ガスの水素に対する第２応答特性を有する。一方、第１ガスセンサ２６は傾きがα１となる硫化水素に対する第１応答特性を有する。第一ガスセンサ２６と第２ガスセンサ２７の出力をそれぞれV1とV2とし、硫化水素濃度および水素濃度をそれぞれ[H2S] と[H2]とすると、出力とガス濃度との間に以下の関係が成り立つ。
V1＝α１[H2S]＋β[H2] 式８
V2＝ β[H2] 式９
硫化水素除去部によって硫化水素が除去されているので、式９に示すように、第２ガスセンサ２７の出力に硫化水素による寄与が含まれていない。式８と式９から、硫化水素濃度[H2S]が以下の式により求まる：
[H2S]＝(V1−V2)/α１ 式１０
すなわち、本実施例では、第一ガスセンサ２６の硫化水素に対する第１応答特性のみ用いて硫化水素の濃度を算出する。
硫化水素濃度を演算する演算部９は第１の実施例と同様に、第１演算部と第２演算部を含む。第一演算部では第１の実施例と同様な動作で、第１ガスセンサ２６および第２ガスセンサ２７の出力V1およびV2を求める。第２演算部では、第１ガスセンサ２６の第一応答特性（図７または式１０のα１）から導いたセンサ出力から硫化水素濃度へ変換する変換表が予め記憶されており、第１演算部で得られたセンサ出力V1およびV2から、記憶されているセンサ出力を硫化水素濃度への変換表を用いて、センサの出力信号に対応する硫化水素濃度を算出する。
以上、３つの実施例を用いて本発明の健康状態測定装置の構成および硫化水素濃度から腸内状態を測定する動作について説明した。
最後に、本発明の健康状態測定装置を使用した健康状態測定方法の手順を例示して説明する。 When the calculation unit 9 simultaneously transmits a measurement start signal to the first gas sensor 24 and the second gas sensor 25 and both gas sensors start to operate, an output signal corresponding to the gas concentration of the gas in contact with the sensor is obtained. Sensor output signals obtained by the gas sensor 21 and the gas sensor 22 are sent to the calculation unit 9 and stored in time series. Further, the operation of both gas sensors is ended by the measurement end signal of the calculation unit 9, and the recording of the sensor output signal is ended. Subsequently, the calculation unit 9 obtains the gas concentration from the sensor output signal stored in accordance with the method described later, and transmits the result to the control unit 8, where the intestinal state index is estimated, and the obtained intestinal state is obtained. The indicator is displayed on the display unit 10.
In the present embodiment, the first gas sensor 24 arranged on the upstream side of the hydrogen sulfide removing section has a first response characteristic for hydrogen sulfide and a second response characteristic for a coexisting gas (hydrogen in this embodiment). Further, the second gas sensor 25 arranged on the downstream side of the hydrogen sulfide removing unit has a second response characteristic with respect to the coexisting gas (hydrogen in this embodiment). FIG. 5 is a conceptual diagram showing response characteristics of both sensors from the relationship between the gas concentration and the output signal of the sensor. The output signal of the sensor is processed so as to have a linear relationship with the gas concentration. As shown in the figure, the first gas sensor 24 has a first response characteristic for hydrogen sulfide having an inclination of α 1 and a second response characteristic for hydrogen of a coexisting gas having an inclination of β 1 . On the other hand, the second gas sensor 25 has a second response characteristic against hydrogen coexistence gas inclination is beta 2. Assuming that the outputs of the first gas sensor 24 and the second gas sensor 25 are V 1 and V 2 , respectively, and the hydrogen sulfide concentration and the hydrogen concentration are [H 2 S] and [H 2 ], respectively, The relationship holds.
V 1 = α 1 [H 2 S] + β 1 [H 2 ] Equation 5
V 2 = β 2 [H 2 ] Equation 6
Since hydrogen sulfide is removed by the hydrogen sulfide removal unit, as shown in Equation 6, the contribution of hydrogen sulfide is not included in the output of the second gas sensor 25. From Equation 5 and Equation 6, the hydrogen sulfide concentration [H 2 S] is determined by the following equation:
[H 2 S] = (V 1 β 2 −V 2 β 1 ) / α 1 β 2 Formula 7
Similar to the first embodiment, the calculation unit 9 that calculates the hydrogen sulfide concentration includes a first calculation unit and a second calculation unit. The first calculation unit obtains the outputs V1 and V2 of the first gas sensor 24 and the second gas sensor 25 by the same operation as in the first embodiment. In the second arithmetic unit, the first response characteristic of the first gas sensor 24 (α 1 in FIG. 5 or Expression 7) and the second response characteristics of the first gas sensor 24 and the second gas sensor 25 (β 1 , β in FIG. 5 or Expression 7). 2 ) A conversion table for converting the sensor output derived from 2 ) into the hydrogen sulfide concentration is stored in advance, and the stored sensor output is converted into the hydrogen sulfide concentration from the sensor outputs V 1 and V 2 obtained by the first calculation unit. Using the conversion table, the hydrogen sulfide concentration corresponding to the output signal of the sensor is calculated.
The second embodiment of the present invention has been described above. Next, a third embodiment of the present invention will be described.
FIG. 6 is a conceptual diagram showing a third embodiment of the health condition measuring apparatus of the present invention. The apparatus configuration of the present embodiment is the same as that of the second embodiment shown in FIG. 4 except that the first gas sensor 26 disposed on the upstream side of the hydrogen sulfide removing unit 23 and the downstream side of the hydrogen sulfide removing unit 23 are disposed. The second gas sensor 27 is different in that it has the same second response characteristic with respect to the coexisting gas (hydrogen in this embodiment). FIG. 7 is a conceptual diagram showing response characteristics of both sensors from the relationship between the gas concentration and the output signal of the sensor. The output signal of the sensor is processed so as to have a linear relationship with the gas concentration. As shown in the figure, both the first gas sensor 26 and the second gas sensor 27 have a second response characteristic with respect to hydrogen of the coexisting gas having an inclination of β. On the other hand, the first gas sensor 26 has a first response characteristic with respect to hydrogen sulfide having an inclination of α 1 . Assuming that the outputs of the first gas sensor 26 and the second gas sensor 27 are V 1 and V 2 respectively, and the hydrogen sulfide concentration and the hydrogen concentration are [H 2 S] and [H 2 ], respectively, The relationship holds.
V 1 = α 1 [H 2 S] + β [H 2 ] Equation 8
V 2 = β [H 2 ] Equation 9
Since hydrogen sulfide is removed by the hydrogen sulfide removal unit, as shown in Expression 9, the output of the second gas sensor 27 does not include the contribution of hydrogen sulfide. From equations 8 and 9, the hydrogen sulfide concentration [H 2 S] is determined by the following equation:
[H 2 S] = (V 1 −V 2 ) / α 1 formula 10
That is, in this embodiment, the concentration of hydrogen sulfide is calculated using only the first response characteristic of the first gas sensor 26 with respect to hydrogen sulfide.
Similar to the first embodiment, the calculation unit 9 that calculates the hydrogen sulfide concentration includes a first calculation unit and a second calculation unit. The first calculation unit obtains the outputs V 1 and V 2 of the first gas sensor 26 and the second gas sensor 27 by the same operation as in the first embodiment. In the second calculation unit, a conversion table for converting the sensor output derived from the first response characteristic of the first gas sensor 26 (α 1 in FIG. 7 or Equation 10) into the hydrogen sulfide concentration is stored in advance, and the first calculation unit From the sensor outputs V 1 and V 2 obtained in step 1 , the stored sensor output is converted into the hydrogen sulfide concentration, and the hydrogen sulfide concentration corresponding to the sensor output signal is calculated.
The operation of measuring the intestinal state from the configuration and the hydrogen sulfide concentration of the health condition measuring apparatus of the present invention has been described above using the three embodiments.
Finally, the procedure of the health condition measuring method using the health condition measuring apparatus of the present invention will be exemplified and described.

図８は、本発明の健康状態測定装置（洋式便器に付設された衛生洗浄便座装置に内蔵）を使用した健康状態測定方法の手順を示す一例である。使用者（以後、「ユーザ」と呼ぶ。）の動作を左側に、便座装置が行う処理（健康状態測定装置の処理を含む）を右側に別けて表示した。 FIG. 8 is an example showing a procedure of a health condition measuring method using the health condition measuring apparatus of the present invention (built in a sanitary washing toilet seat apparatus attached to a Western-style toilet). The operation of the user (hereinafter referred to as “user”) is displayed on the left side, and the process performed by the toilet seat device (including the process of the health condition measuring apparatus) is displayed separately on the right side.

本図の流れの通り、ユーザはトイレ内に入室し排便をして退室するのであるが、このトイレには本発明の健康状態測定装置が取り付けてあるため、退室する前には自分の腸内のｐＨ推定値を表示部１０に表示されることで、その日の体調を知り、あるいは継続的に測定していた場合は経時的な体調の変化を知ることができる。 As shown in the flow of this figure, the user enters the toilet, defecates, and then exits, but since the health condition measuring device of the present invention is attached to this toilet, By displaying the estimated pH value on the display unit 10, it is possible to know the physical condition of the day, or to know the change in physical condition over time when continuously measured.

まずユーザが入室すると人体検知センサによって入室が検知され、２つのガスセンサからなるガスセンサ７が同時に起動される。人体検知センサを使わない場合には、ユーザが健康状態測定装置の電源を手動で入れてもよい。 First, when a user enters a room, the human body detection sensor detects the entry, and the gas sensor 7 including two gas sensors is activated simultaneously. When the human body detection sensor is not used, the user may manually turn on the health condition measuring device.

ユーザが着座すると着座センサが着座を検知し、脱臭ファン５の起動後にガスセンサ７が記録および記憶を開始する。着座センサを使わずにユーザが各センサの始動スイッチを押してもよい。ここで稼動開始時のセンサの時刻をｔ１とし、その時刻に対応する二酸化炭素２つのガスセンサの出力値をそれぞれＶ１１とＶ２１と呼ぶ。 When the user is seated, the seating sensor detects the seating, and after the deodorizing fan 5 is activated, the gas sensor 7 starts recording and storage. The user may press the start switch of each sensor without using the seating sensor. Here, the time of the sensor at the start of operation is defined as t1, and the output values of the two carbon dioxide gas sensors corresponding to the time are referred to as V11 and V21, respectively.

ユーザが排便を開始し終了するまで、ガスセンサ７は一定時間ｔｘ、たとえば１秒おきに両ガスセンサの出力信号Ｖ１ｘ、Ｖ２ｘを検出し、それぞれ演算部９に書き込む。 Until the user starts and finishes defecation, the gas sensor 7 detects the output signals V1x and V2x of both gas sensors at a predetermined time tx, for example, every second, and writes them to the calculation unit 9 respectively.

排便終了後、ユーザが人体洗浄を開始する。このとき、洗浄ボタンと連動させてガスセンサ７の記録を終了させる。排便終了時の時間ｔ２とガスセンサ７のそのときの検知データＶＶ１２とＶ２２が記憶される。なお、排便前または排便中に洗浄ボタンが使われるケースもあることを考慮する場合は、洗浄ボタンと連動させずにユーザが手動で記憶終了させる形式としてもよい。 After defecation ends, the user starts washing the human body. At this time, the recording of the gas sensor 7 is terminated in conjunction with the cleaning button. The time t2 at the end of the defecation and the detection data VV12 and V22 at that time of the gas sensor 7 are stored. When considering that the washing button may be used before or during defecation, the user may manually terminate the storage without interlocking with the washing button.

演算部９の第１演算部では、まずｔ１〜ｔ２の範囲でそれぞれのガスセンサの出力の最大値（Ｖ１ｍａｘまたはＶ２ｍａｘ）を検索する。そして最大値そのもの、またはセンサの最小出力をベースとした相対値をそれぞれのセンサの出力V1およびV2算出する。そして演算部９の第２演算部では予め演算部に記憶されている両ガスセンサ第１応答特性おとび第２応答特性から導かれたガスセンサの出力V1およびV2と硫化水素濃度との対応表から硫化水素濃度を算出する。 The first calculation unit of the calculation unit 9 first searches for the maximum value (V1max or V2max) of the output of each gas sensor in the range of t1 to t2. Then, the maximum value itself or a relative value based on the minimum output of the sensor is calculated as outputs V 1 and V 2 of the respective sensors. The correspondence table of the second output V 1 and V 2 and the concentration of hydrogen sulfide derived from the second response characteristic jump Contact both gas sensor first response characteristics stored in advance in the arithmetic unit gas sensor in the calculating portion of the calculation unit 9 The hydrogen sulfide concentration is calculated from

最後に、制御部８では、硫化水素濃度をそのまま腸内状態指標として、またはさらに別の腸内状態指標に変換してユーザに表示部１０等により報知する。 Finally, the control unit 8 notifies the user of the hydrogen sulfide concentration as it is as an intestinal state index or further converted into another intestinal state index through the display unit 10 or the like.

ユーザが離座すると、それを着座センサが感知し脱臭ファン５が停止する。そしてユーザが退室すると人体検知センサによって退室が検知され二酸化炭素ガスセンサ７の電源が切られる。
よって使用者が通常のトイレ行為で手軽に自分の腸内状態を知ることができる。
When the user leaves the seat, the seating sensor senses it and the deodorizing fan 5 stops. When the user leaves the room, the human body detection sensor detects the room leaving and the carbon dioxide gas sensor 7 is turned off.
Therefore, the user can easily know his / her intestinal state by a normal toilet action.
