【００６０】
ここで、λは端末装置１の熱伝導率、λ_hは使用者Ｈの皮膚内部の熱伝導率、δは端末装置１の厚さ寸法、δ_hは使用者Ｈの皮膚表面から体内温度Ｔiとなる位置までの深さ寸法をそれぞれ示している。そして、数１の式から熱流束ｑを除去すると、数２の式に示すように、体内温度Ｔiは、体表温度検出データＴsと外気温度検出データＴaとを用いて算出することができる。
【００６１】
【数２】

【００６２】
次に、外気温度Ｔaを予め決められた一定温度ＴAとし、このときの体表温度を修正体表温度Ｔs′とすると、体内温度Ｔiは、数２の式と同様に以下の数３の式のように表すことができる。なお、定数Ｋは、各種の物性データ、臨床データ等に基づいて最適な値を予め求めておくことが可能である。
【００６３】
【数３】

【００６４】
そして、この数３の式に基づいて、外気温度を一定値ＴAとしたときの体表温度（修正体表温度Ｔs′）は、以下に示す数４の式により算出することができる。
【００６５】
【数４】

【００６６】
この結果、数２および数４の式を用いることによって、外部環境を一定状態にした場合の修正体表温度Ｔs′を演算することができる（図１２参照）。
【００６７】
次に、ステップ４では、各時間間隔Δt毎の体表温度検出データＴs（差分値ΔＴs）の時間的変動幅ΔＳ（ΔＳ＝Ｔs[i]−Ｔs[i-1]）を演算すると共に、外気温度検出データＴa（差分値ΔＴa）の時間的変動幅ΔＡ（ΔＡ＝Ｔa[i]−Ｔa[i-1]）を演算する。即ち、測定時点第ｉ番目の検出データＴs[i]，Ｔa[i]と第ｉ−１番目の検出データＴs[i-1]，Ｔa[i-1]との差分を時間的変動幅ΔＳ，ΔＡとするものである。
【００６８】
次に、ステップ５では、以下の数５の式に示すように、ステップ４で演算した時間的変動幅ΔＳ，ΔＡの二乗和を温度平衡指数β（図１２中の破線参照）として用い、この温度平衡指数βが予め決められた零に近い判定値β0（例えば、β0＝０．０１〜０．０９）よりも小さいか否かを判定する。
【００６９】
【数５】

【００７０】
そして、ステップ５では、図１２に示すように、温度平衡指数βが判定値β0よりも小さい（β＜β0）時刻は、端末装置１は温度変化が少ない熱平衡状態にあると判定し、温度平衡指数βが判定値β0以上（β≧β0）となる時刻は、端末装置１は例えば加熱中または冷却中のような熱非平衡状態であると判定する。
【００７１】
次に、ステップ６では、ステップ５で熱平衡状態にあると判定した時刻の修正体表温度Ｔs′を代表温度候補として抽出し、熱非平衡状態にあると判定した時刻の修正体表温度Ｔs′は代表温度候補から除外する。
【００７２】
次に、ステップ７では、ステップ６で抽出した複数の代表温度候補（修正体表温度Ｔs′）の中から最高温度となるものを代表温度Ｔdとして選択する。そして、コントロールユニット９は、開始時刻ｔ1から終了時刻ｔ2までの代表温度Ｔd（就寝した日の代表温度Ｔd）を表示部６に表示すると共に、代表温度Ｔdを記憶部１０に記憶し、ステップ８に移って代表温度特定プログラムを終了する。
【００７３】
最後に、使用者Ｈは、第１の実施の形態と同様に、接続部１２を携帯電話、携帯端末、コンピュータ等の外部情報機器１３に中継ケーブル１４を介して接続する。このとき、中継ケーブル１４の途中には記憶部１０内の差分値ΔＴs，ΔＴa、代表温度Ｔd等のデータを外部情報機器１３で読取り可能なデータに変換する通信仲介装置１５が接続されている。これにより、記憶部１０に記憶された１日分の差分値ΔＴs，ΔＴa、代表温度Ｔd等を外部情報機器１３に伝送することができるから、外部情報機器１３自体または当該外部情報機器１３を介して接続された外部のサーバコンピュータ等（図示せず）を用いて差分値ΔＴs，ΔＴaを分析し、就寝中の修正体表温度Ｔs′の変動等に基づいて使用者Ｈの体調判断等を行うことができる。
【００７４】
また、例えば外部のサーバコンピュータ等には、使用者Ｈの基礎体温に応じた代表温度Ｔdを数日間または数ヶ月間に亘って保存しておくことができる。この結果、外部のサーバコンピュータ等を用いて数日間または数ヶ月間に亘る基礎体温（代表温度Ｔd）の変化を計測することができるから、基礎体温の変化に基づく月経周期等の情報を正確に分析し、使用者Ｈに伝えることができる。
【００７５】
なお、記憶部１０に記憶された差分値ΔＴs，ΔＴa、代表温度Ｔd等は必ずしも毎日外部情報機器１３に出力する必要はなく、記憶部１０の容量に応じて数日間分の差分値ΔＴs，ΔＴa等をまとめて外部情報機器１３に出力する構成としてもよい。このように、差分値ΔＴs，ΔＴa等を複数日分をまとめて出力することによって、外部情報機器１３に対して差分値ΔＴs，ΔＴa等を出力する操作の手間を省くことができる。
【００７６】
また、本実施の形態では、端末装置１内のコントロールユニット９によって代表温度Ｔdを特定するものとしたが、差分値ΔＴs，ΔＴaを受け取った外部情報機器１３や外部のサーバコンピュータ等を用いて代表温度Ｔdを特定する構成としてもよい。この場合、コントロールユニット９に対して代表温度Ｔdの特定に伴う処理負担を軽減することができる。
【００７７】
かくして、本実施の形態では、身体に常時装着可能なケーシング２には、体表温度検出部４による体表温度検出データＴ s と外気温度検出部５による外気温度検出データＴ a とを一定の時間間隔Δｔで読込むコントロールユニット９を設けると共に、該コントロールユニット９よって読込んだ検出データＴ s ，Ｔ a に基づく差分値ΔＴ s ，ΔＴ a を記憶する記憶部１０を設ける構成としたから、使用者Ｈはケーシング２を身体に装着した状態で就寝することができ、起床中に比べて身体温度が安定している就寝中の身体温度を測定することができる。
【００７８】
また、コントロールユニット９は、例えば５分程度の一定の時間間隔Δｔ毎に体表温度 検出部４による体表温度検出データＴ s と外気温度検出部５による外気温度検出データＴ a とを読込み、これらの検出データＴ s ，Ｔ a に基づいて演算した基準温度数値Ｔ 0 との差分値ΔＴ s ，ΔＴ a を記憶部１０に記憶するから、就寝中の体温に対応した差分値ΔＴ s ，ΔＴ a を用いることによって使用者Ｈの身体温度を正確に求めることができると共に、基礎体温の変動幅や月経周期を正確に把握することができる。
【００７９】
また、ケーシング２にはクリップ３を設けたから、肌と接触する下着にクリップ３を容易に取付けることが可能となると共に、ケーシング２を下着によって覆うことができる。この結果、身体温度の変動が反映され易い内臓の近くにあり、下着等に覆われているために外気温変動に影響され難い腹部Ａに体表温度検出部４を接触させることができるから、下着で保温されている腹部の温度を測定することができると共に、下着によって外気温度の影響を軽減することができ、正確な体表の温度を検出することができる。
【００８０】
さらに、ケーシング２を腹部Ａに装着したときには、身体の他の部位に装着したときに比べて、特に就寝中にケーシング２が測定部位から位置ずれし難くなるため、位置ずれによる測定誤差も軽減することができ、検出精度を高めることができる。
【００８１】
また、基準温度数値Ｔ 0 は外部から更新可能な構成としたから、平均的な体表温度の個人差に応じて基準温度数値Ｔ 0 を設定でき、使用者Ｈ毎に体表温度の平均値が異なる場合でも、体温の変動分だけを体表温度情報として記憶し、体表温度情報のデータ量を低減することができる。
【００８２】
また、体表温度検出部４は、ケーシング２から突出したカバー部材４Ａと、該カバー部材４Ａによって覆われた測温素子４Ｂと、該測温素子４Ｂとカバー部材４Ａとの間に設けられた熱伝導シート４Ｃとによって構成したから、ケーシング２から突出したカバー部材４Ａを体表に容易に接触させることができると共に、体表の温度をカバー部材４Ａと熱伝導シート４Ｃを通じて測温素子４Ｂに低損失で伝達でき、測温素子４Ｂを用いて体表の温度を正確に検出することができる。
【００８３】
また、本実施の形態では、ケーシング２の背面側には外気の温度を検出する外気温度検出部５を設けたから、体表温度検出部４によって体表の温度を検出するのに加えて、外気温度検出部５によって外気の温度を検出することができる。そして、記憶部１０には体表温度検出データＴsによる差分値ΔＴsと外気温度検出データＴaによる差分値ΔＴaとを記憶するから、差分値ΔＴsが外気の影響によって変動する場合であっても、外気温度検出データＴa（差分値Ｔa）を用いて差分値ΔＴsを修正することができる。
【００８４】
特に、本実施の形態では、外気温度検出データＴa（差分値ΔＴa）を用いて外部環境が一定状態の体表温度検出データＴsを修正体表温度Ｔs′として演算するから、例えば使用者Ｈが旅行等によって沖縄等の温かい地域から北海道等の寒い地域に移動したときでも、外部環境の変化に影響されず、正確な修正体表温度Ｔs′を算出し、この修正体表温度Ｔs′を用いて基礎体温に対応した正確な代表温度Ｔdを特定することができる。
【００８５】
また、コントロールユニット９は、体表温度検出データＴsの時間的変動幅ΔＳと外気温度検出データＴaの時間的変動幅ΔＡとを用いてケーシング２等の温度変化が少ない熱平衡状態にあるか否かを判定し、熱平衡状態のみの修正温度情報Ｔs′を代表温度候補として抽出し、これらの代表温度候補のうちで最高温度となるものを代表温度Ｔdとして選択するから、使用者Ｈの体温によってケーシング２、体表温度検出部４等が十分に温められた熱平衡状態の修正温度情報Ｔs′を就寝した日の代表温度Ｔdとして特定することができる。このため、代表温度Ｔdを使用者の身体温度（基礎体温）に正確に対応させることができるから、代表温度Ｔdを用いて基礎体温の変化に基づく月経周期等の情報を正確に把握することができる。
【００８６】
また、体表温度検出部４をケーシング２の正面側に配置すると共に、外気温度検出部５はケーシング２の背面側に配置したから、ケーシング２を挟んで体表温度検出部４と外気温度検出部５とを反対側に配置することができ、体表温度検出部４が使用者Ｈの体表（皮膚）に接触したときには、外気温度検出部５を使用者Ｈの体表に対して確実に非接触な状態にでき、外気温度検出部５によって外気温度を正確に検出することができる。
【００８７】
さらに、外気温度検出部５をクリップ３によって覆うから、寝返り時等に外気温度検出部５が腕等に接触するのをクリップ３によって防ぐことができ、外気温度検出データＴaの信頼性を高めることができる。また、クリップ３によって外気温度検出部５を保護することができるから、外気温度検出部５の破損を防止でき、信頼性、耐久性を高めることができる。
【００８８】
また、コントロールユニット９は開始時刻ｔ1から終了時刻ｔ2までの間に亘って体表温度検出部４から検出データＴsを読込むと共に、外気温度検出部５から検出データＴaを読込む構成としたから、コントロールユニット９は、予め設定された深夜等の開始時刻ｔ1から起床前の終了時刻ｔ2までの間に亘って一定の時間間隔Δｔ毎に検出データＴs，Ｔaを読込むことができ、記憶部１０はこの検出データＴs，Ｔaに基づいて就寝中の複数の体表温度情報（差分値ΔＴs）および外気温度情報（差分値ΔＴa）を自動的に記憶することができる。さらに、コントロールユニット９はタイマ１１を備えるから、検出データＴs，Ｔaを読込んだ時刻を検出データＴs，Ｔaと一緒に記憶することもできる。
【００８９】
また、記憶部１０には基準温度数値Ｔ0と検出データＴsの数値との差分値ΔＴsを体表温度情報として記録すると共に、基準温度数値Ｔ0と検出データＴaの数値との差分値ΔＴaを外気温度情報として記録する構成としたから、例えば基準温度数値Ｔ0を使用者Ｈの平均的な腹部Ａの体表温度に設定することによって、就寝中の体温の変動分だけを体表温度情報や外気温度情報記憶することができる。この結果、記憶する体表温度情報や外気温度情報のデータ量を低減でき、ＲＡＭ等の記憶素子の容量を小さくし、装置全体を小型化、低コスト化できると共に、記憶する体表温度情報および外気温度情報を増加させることができる。
【００９０】
また、ケーシング２には、記憶部１０に記憶した体表温度情報（差分値ΔＴs）および外気温度情報（差分値ΔＴa）を外部に出力する接続部１２を設けたから、接続部１２を介して外部情報機器１３に体表温度情報および外気温度情報を出力することができると共に、該外部情報機器１３をネットワーク網に接続することによって、外部のサーバコンピュータ等を用いて体表温度情報および外気温度情報の分析を行うことができ、使用者は各種のサービスを受けることができる。
【００９１】
なお、前記第１の実施の形態では、図１１中のステップ３〜７が代表温度特定手段の具体例を示している。また、図１１中のステップ３が温度情報修正手段の具体例を示し、ステップ４が変動幅演算手段の具体例を示し、ステップ５が熱平衡状態判定手段の具体例を示し、ステップ６が代表温度候補抽出手段の具体例を示し、ステップ７が代表温度選択手段の具体例を示している。ここで、図１１中のステップ３はステップ４，５の後に行われても構わない。
【００９２】
また、第１の実施の形態では、ケーシング２の側面側（正面および背面を除いた他の面）からの外部に伝わる熱流束はないものと仮定したが、このような仮定を成立させるために、例えば図５中に二点鎖線で示すようにケーシング２の側面側には断熱材や、外気と遮断された空気層を断熱手段２１として設ける構成としてもよい。
【００９３】
また、前記第１の実施の形態では、身体温度情報端末装置１と外部情報機器１３とを接続する中継ケーブル１４の途中にデータ変換用の通信仲介装置１５を接続するものとした。しかし、本発明はこれに限らず、図１３に示す第１の変形例のように、端末装置１と外部情報機器１３とでデータ変換が不要な場合には、中継ケーブル１４だけを用いて接続する構成としてもよい。
【００９４】
また、データ変換が不要な場合には、温度情報出力手段として外部情報機器１３の既存のコネクタに接続可能なコネクタ２２を採用することによって、図１４に示す第２の変形例のように、端末装置１と外部情報機器１３とを直接接続する構成としてもよい。
【００９５】
また、前記第１の実施の形態では、端末装置１と外部情報機器１３との間を中継ケーブル１４を用いて有線接続するものとした。しかし、本発明はこれに限らず、例えば図１５に示す第３の変形例のように、超音波、赤外線、電磁波、磁気誘導、静電誘導等を用いて無線接続する構成としてもよい。この場合、例えば電磁波等を放射する内蔵のアンテナ２３等によって温度情報出力手段を構成するものである。
【００９６】
また、端末装置１と外部情報機器１３とを磁気誘導等を用いて無線接続する場合には、図１６に示す第４の変形例のように、ケーシング２内に温度情報出力手段として磁気誘導用のコイル部材２４を取付けると共に、端末装置１のケーシング２を磁気誘導用の端子を内蔵した通信仲介装置２５に載置することによって端末装置１と外部情報機器１３とを接続してもよい。この場合、通信仲介装置２５はデータ変換機能を備える構成としてもよく、通信仲介装置２５と外部情報機器１３との間は例えば中継ケーブル２６を用いて接続する構成とするものである。
【００９７】
さらに、前記第１の実施の形態では、体表温度検出部４のカバー部材４Ａと測温素子４Ｂとの間に熱伝導部材としての熱伝導シート４Ｃを挟む構成とした。しかし、本発明はこれに限らず、例えば図１７に示す第５の変形例のように、例えばカバー部材４Ａと測温素子４Ｂとの間には熱伝導部材として熱伝導性を有する例えばシリコン系の熱伝導材料２７を充填する構成としてもよい。また、カバー部材４Ａに表面側が覆われた測温素子４Ｂに対して、その背面側を断熱部材２８によって覆う構成としてもよい。これにより、体表の熱は確実に測温素子４Ｂに伝達できると共に、伝わった熱が測温素子４Ｂの背面側から逃げるのを防ぐことができ、正確な体表の温度を検出することができる。
【００９８】
また、前記第１の実施の形態では、ケーシング２を腹部Ａに装着するための装着手段としてクリップ３を用いる構成とした。しかし、本発明はこれに限らず、例えば装着手段として下着Ｂにピン止めが可能な安全ピン等を用いる構成としてもよい。また、ケーシング２は下着Ｂを用いて装着する場合に限らず、ケーシング２に装着手段として例えばベルト等を取付けることによって、該ベルトを用いてケーシング２を身体に装着する構成としてもよい。
【００９９】
次に、図１８は本発明の第２の実施の形態による身体温度情報処理システムを示し、本実施の形態の特徴は、身体温度情報端末装置を外部情報機器を介してネットワーク網に接続し、外部のサーバコンピュータ等によって体表温度情報の分析を行い、使用者Ｈに対してこの分析結果を視覚情報および／または音声情報として提供することにある。なお、本実施の形態では、第１の実施の形態と同様の構成要素に同一の符号を付し、その説明を省略するものとする。
【０１００】
３１は第１の実施の形態および第１〜第５の変形例のうちいずれかの（図１８は第４の変形例に適用した場合を示す）身体温度情報端末装置１および外部情報機器１３等と共に身体温度情報処理システムを構成するサーバコンピュータ等の外部情報処理装置で、該外部情報処理装置３１は、インターネット等のネットワーク網３２を介して携帯電話等の外部情報機器１３に接続されている。そして、外部情報処理装置３１は、端末装置１から出力される体表温度情報を分析し、その分析結果を外部情報機器１３等に出力するプログラムを作動させ、温度情報取得手段、分析手段および分析結果出力手段として機能するものである。
【０１０１】
本実施の形態による身体温度情報処理システムは上述の如き構成を有するもので、次にその動作について説明する。
【０１０２】
まず、使用者Ｈは１日分または数日分の体温情報が記憶された身体温度情報端末装置１を通信仲介装置２５等を介して外部情報機器１３に接続する。そして、使用者Ｈは、外部情報機器１３をネットワーク網３２を介して外部情報処理装置３１に接続し、外部情報機器１３から外部情報処理装置３１に対して体表温度情報の分析を指示する信号を送信する。
【０１０３】
これにより、外部情報処理装置３１は、外部情報機器１３からの指示に応じて端末装置１から温度情報出力手段として磁気誘導用のコイル部材２４等を用いて体表温度情報や外気温度情報を取得し、第１の実施の形態によるコントロールユニット９とほぼ同様の演算処理を行うことによって、この取得した体表温度情報や外気温度情報を分析して基礎体温に応じた身体温度（代表温度Ｔd）を算出する。このとき、使用者Ｈの身体温度の情報を例えば３ヶ月分程度まで予め外部情報処理装置３１等に記憶しておくことによって、日毎の基礎体温の変動を知ることができる。このため、外部情報処理装置３１は、取得した体表温度情報を測定した日の基礎体温や数日間から数ヶ月間の基礎体温の変動の基づく例えば女性の月経周期や女性ホルモンバランス情報等の分析結果を得ることができる。
【０１０４】
最後に、外部情報処理装置３１は、体表温度情報等の分析結果を文字情報、基礎体温の変動を示すグラフ等の図形情報、音声情報等として外部情報機器１３に出力する。これにより、使用者Ｈは当日の基礎体温や月経周期を認識できると共に、分析結果を体調管理や健康管理に役立てることができる。
【０１０５】
かくして、本実施の形態でも前記第１の実施の形態と同様の作用効果を得ることができるが、本実施の形態では、本発明による身体温度情報端末装置１を用いるから、他の体温計等を用いた場合に比べて、長期間に亘って無理なく、かつ正確に体温（体表温度情報）を計測することができる。そして、このように計測した体表温度情報をネットワーク網３２に接続された外部情報処理装置３１によって分析する構成としたから、端末装置１を体温の計測、記憶にのみ用いることができ、小型化、軽量化を図ることができ、就寝中の常時装着が容易になる。一方、外部情報処理装置３１は、端末装置１が記録した体表温度情報や外気温度情報を用いるから、基礎体温の変動を正確に算出することができ、従来技術に比べて正確な月経周期等の分析結果を使用者Ｈに伝えることができる。特に、分析結果を聴覚的に出力した場合には、視覚障害者に対しても認識可能な情報を提供することができる。
【０１０６】
なお、分析結果の出力先（送信先）は外部情報機器１３に限らず、使用者Ｈに要求に応じて例えば使用者Ｈの携帯電話等であってもよい。
【０１０７】
また、外部情報処理装置３１は、使用者Ｈとの間で予め体表温度情報の分析に関する契約手続を行う、または体表温度情報の分析を指示する毎にネットワーク網３２を介して契約手続を行うことによって、分析結果を取得した使用者Ｈから利用料金を徴収する構成としてもよい。
【０１０８】
さらに、前記各実施の形態では、主として成人女性の使用者に端末装置１を装着するものとして説明した。しかし、本発明はこれに限らず、例えば自ら体温測定が困難な新生児、幼児、介護老人、動物等に端末装置１を装着する構成としてもよい。これにより、新生児等の身体温度の変動を把握して健康状態等を判別できると共に、疾病時の身体温度の急激な変動による体調変化を把握でき、さらには不慮の事態による死亡推定時刻の把握にも役立てることができる。
【０１０９】
【発明の効果】
以上詳述した如く、請求項１の発明によれば、身体に常時装着可能なケーシングには、体表温度検出手段による体表検出データを一定の時間間隔で読込むデータ読込み手段を設けると共に、該データ読込み手段よって読込んだ体表検出データに基づく体表温度情報を記憶する記憶手段を設ける構成としたから、使用者はケーシングを身体に装着した状態で就寝することができ、起床中に比べて体温が安定している就寝中の体温を測定することができる。また、データ読込み手段は、一定の時間間隔毎に体表温度検出手段による体表温度検出データを読込み、記憶手段はこの検出データに基づいた体表温度情報を記憶するから、就寝中の体温に対応した体表温度情報を用いることによって使用者の基礎体温に応じた身体温度を正確に求めることができると共に、基礎体温の変動幅や月経周期を正確に把握することができる。
【０１１０】
即ち、本発明によれば、端末内に測定したい時刻を就寝中である深夜または早朝に設定しておくことにより、翌朝目覚めた任意の時間には所望の時刻の変位がすでに内部に記録されているため、基礎体温の日ごとの変動を数ヶ月間に亘って追跡記録することは非常に容易になり、簡便に女性の月経周期やホルモンバランスのリズムを知る手掛かりを得ることができる。この結果、思春期から閉経期までのすべての女性が簡便に利用でき、従来妊娠や避妊の目的以外にはあまり利用されることのなかった基礎体温計測を、女性ホルモンバランス情報を利用した健康管理の有効な手段とすることができる。
【０１１１】
また、ケーシングには外気の温度を検出する外気温度検出手段を設けたから、体表温度検出手段によって体表の温度を検出するのに加えて、外気温度検出手段によって外気の温度を検出することができる。そして、データ読込み手段は体表温度検出データと外気温度検出データとを一定の時間間隔で一緒に読込み、記憶手段は体表温度検出データによる体表温度情報と外気温度検出データによる外気温度情報とを記憶するから、体表温度情報が外気の影響によって変動する場合であっても、外気温度検出データを用いて体表温度情報を修正することができる。
また、外気温度情報を用いて外部環境が一定状態の体表温度情報を修正温度情報として演算するから、例えば使用者が旅行等によって外気温度が著しく異なる場所に移動したときでも、外部環境の変化に影響されず、正確な修正温度情報を算出し、この修正温度情報を用いて基礎体温に対応した正確な代表温度を特定することができる。
また、熱平衡状態判定手段は、体表温度情報の時間的変動幅と外気温度情報の時間的変動幅とを用いてケーシング等が熱平衡状態にあるか否かを判定し、熱平衡状態のみの修正温度情報を代表温度候補として抽出し、これらの代表温度候補のうちで最高温度となるものを代表温度として選択するから、使用者の体温によってケーシング、体表温度検出手段等が十分に温められた熱平衡状態の修正温度情報を就寝した日の代表温度として特定することができる。このため、代表温度を使用者の身体温度（基礎体温）に正確に対応させることができるから、代表温度を用いて基礎体温の変化に基づく月経周期等の情報を正確に把握することができる。
【０１１５】
請求項２の発明によれば、体表温度検出手段は体表に接触可能な状態でケーシングの正面側に配置し、外気温度検出手段はクリップに覆われた状態でケーシングの背面側に配置する構成としたから、ケーシングを挟んで体表温度検出手段と外気温度検出手段とを反対側に配置することができ、体表温度検出手段が使用者の体表に接触したときには、外気温度検出手段を使用者の体表に対して確実に非接触な状態にでき、外気温度検出手段によって外気温度を正確に検出することができる。
【０１１６】
また、外気温度検出手段をクリップによって覆うから、寝返り時等に外気温度検出手段が腕等に接触するのをクリップによって防ぐことができ、外気温度検出データの信頼性を高めることができる。また、クリップによって外気温度検出手段を保護することができるから、外気温度検出手段の破損を防止でき、信頼性、耐久性を高めることができる。
【０１１７】
請求項３の発明によれば、記憶手段には基準温度数値と体表温度検出データの数値との差分値を体表温度情報として記録し、基準温度数値と外気温度検出データの数値との差分値を外気温度情報として記録する構成としたから、例えば基準温度数値を使用者の平均的な体表温度に設定することによって、測定中の体温の変動分（±３．０℃程度）だけを体表温度情報または外気温度情報として記憶することができる。この結果、例えば３６．４０℃程度の体温の絶対値を記憶するのに比べて、記憶する各温度情報のデータ量を削減でき、ＲＡＭ等の記憶素子の容量を小さくし、装置全体を小型化、低コスト化できると共に、記憶する体表温度情報および外気温度情報を増加させることができる。
【０１１８】
請求項４の発明によれば、基準温度数値を外部から更新可能な構成としたから、平均的な体表温度の個人差に応じて基準温度数値を設定でき、使用者毎に体表温度の平均値が異なる場合でも、体温の変動分だけを温度情報として記憶し、温度情報のデータ量を低減することができる。
【０１１９】
請求項５の発明によれば、ケーシングには、記憶手段に記憶した体表温度情報および外気温度情報を外部に出力する温度情報出力手段を設けたから、温度情報出力手段を介して外部情報機器に体表温度情報および外気温度情報を出力することができると共に、該外部情報機器をネットワーク網に接続することによって、外部のサーバコンピュータ等を用いて体表温度情報および外気温度情報の分析等を行うことができ、使用者はこれらの温度情報に基づく各種のサービスを受けることができる。
【０１２０】
請求項６の発明によれば、身体温度情報端末装置の記憶手段は体表温度情報と外気温度情報とを記憶すると共に、温度情報取得手段を用いて身体温度情報端末装置の記憶手段に記憶した体表温度情報と外気温度情報を取得し、分析手段を用いてこれらの体表温度情報と外気温度情報を分析する構成としたから、分析結果出力手段を用いて、例えば女性の月経周期や女性ホルモンバランス情報等の分析結果を視覚的または聴覚的に外部の携帯電話等に出力することができる。
【０１２１】
また、分析手段は体表温度情報と外気温度情報とを分析するから、例えば体表温度情報が外気の影響によって変動する場合であっても、分析手段は、外気温度情報を用いて体表温度情報を修正することができ、例えば女性の月経周期や女性ホルモンバランス情報等を正確に分析することができる。
また、熱平衡状態判定手段は体表温度情報の時間的変動幅と外気温度情報の時間的変動幅とを用いてケーシング等が熱平衡状態にあるか否かを判定し、代表温度候補抽出手段は熱平衡状態の修正温度情報を代表温度候補として抽出すると共に、代表温度選択手段はこの代表温度候補のうちで最高温度となるものを選択する構成としたから、使用者の体温によってケーシング、体表温度検出手段等が十分に温められた熱平衡状態の修正温度情報を例えば就寝中の代表温度として特定することができ、代表温度を使用者の身体温度（基礎体温）に正確に対応させることができる。この結果、分析手段は、このように特定した代表温度を用いて例えば女性の月経周期や女性ホルモンバランス情報等を正確に分析することができる。
【０１２４】
この場合、請求項７の発明のように、分析結果出力手段による分析結果を取得した使用者から利用料金を徴収してもよい。

BACKGROUND OF THE INVENTION
  The present invention relates to a body temperature information terminal device that constantly wears on the body and measures and collects information that is the basis of a woman's specific menstrual cycle and hormonal balance rhythm, and temperature information collected by the body temperature information terminal device is managed and analyzed In addition, the present invention relates to a body temperature information processing system that distributes various types of information.
[0002]
[Prior art]
  Conventionally, in order to understand the hormonal balance status of women for the purpose of knowing the cycle that is a standard for pregnancy and contraception, daily fluctuations in basal body temperature are tracked over several months, and the fluctuation cycle and fluctuation range are numerical values. Analytical methods have been performed. Basically, basal body temperature is desirable to measure body temperature during sleep, which has the least metabolism during the day, but it is generally difficult to measure body temperature during sleep, so body temperature when waking up is measured. It has been used instead of basal body temperature (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
          JP-A-11-316161
[0004]
[Problems to be solved by the invention]
  By the way, in the prior art, when measuring the basal body temperature, it is necessary to wake up every morning at a certain time, and the user must continue to perform the measurement operation actively. This measurement operation means that the thermometer is kept in close contact with the measurement site such as the sublingual or armpit, and the body is held without moving until reaching thermal equilibrium or until it is calculated to reach thermal equilibrium. is there. In the first place, getting up at a certain time every morning is extremely difficult to continue even in view of today's lifestyle, and maintaining the measurement operation every day is extremely painful for the user. It is. Moreover, there is a high possibility that the measurement site will be displaced or the measurement will be forgotten, and erroneous data and data omission are likely to occur.
[0005]
  As an improvement measure to record changes in basal body temperature and analyze the fluctuation cycle and fluctuation range, we have also realized a method for accumulating and displaying measurement information and a method for accumulating and analyzing information in external devices and distributing information However, the measurement method itself is still wake up every morning at a certain time and the user actively performs the measurement, and the continuous use is troublesome.
[0006]
  In addition, with conventional basal thermometers, the support structure and covering structure including the temperature sensor are made as small as possible for the purpose of speeding up from measurement start to measurement completion or identification, that is, to react quickly to temperature changes. In addition, the thermal resistance was reduced. For this reason, there has been a problem that the temperature at the measurement point changes abruptly due to a slight shift between the temperature measuring element and the measurement site during measurement or the inflow of outside air, which tends to induce fluctuations in the measurement data.
[0007]
  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a body temperature information terminal device and a body temperature information processing system that can eliminate the annoyance of measuring the basal body temperature every morning at a fixed time. It is in.
[0008]
[Means for Solving the Problems]
  In order to solve the above-mentioned problems, the invention of claim 1 is a casing that can be always attached to the body, a body surface temperature detecting means that is provided in the casing and detects the temperature of the body surface, and the body surface temperature detecting means.

An outside air temperature detecting means for detecting the temperature of the air is provided, and the data reading means is, Equipped with a timer that counts the time, with a fixed time interval between the preset start time and end timeOutside air temperature detection data by the outside air temperature detection means together with body surface temperature detection data by the body surface temperature detection meansReadIncludedThe configurationIn addition to the body surface temperature information, the storage means stores outside air temperature information based on outside temperature detection data read by the data reading means.The casing is provided with representative temperature specifying means for specifying a representative temperature from the start time to the end time using the body surface temperature information and the outside air temperature information, and the representative temperature specifying means stores the outside air temperature information. Temperature information correction means for calculating corrected temperature information obtained by correcting body surface temperature information, and a fluctuation range for calculating a temporal fluctuation width of the body surface temperature information and a temporal fluctuation width of the outside air temperature information for each time interval A time when the heat balance state is determined by the heat balance state determining means, the heat balance state determining means for determining whether or not the heat balance state is obtained by using the two time fluctuation widths by the time width calculation means; Representative temperature candidate extracting means for extracting the corrected temperature information as representative temperature candidates, and representative temperature selecting means for selecting the representative temperature candidate having the highest temperature as the representative temperature.It is characterized by that.
[0009]
  With this configuration, the user can go to bed with the casing attached to the body. At this time, the body surface temperature detection means detects the temperature of the body surface of the sleeping user, and the data reading means detects the body surface temperature by the body surface temperature detection means at regular time intervals, for example, every 5 minutes. Read the data. And since a memory | storage means memorize | stores body surface temperature information based on the body surface temperature detection data read by the data reading means, it can record the fluctuation | variation of the body temperature over a fixed period, such as several hours to several days, for example. In addition, by using this body surface temperature information, it is possible to accurately determine the fluctuation range and period of the basal body temperature of the user..
[0010]
  Further, since the casing is provided with the outside air temperature detecting means for detecting the outside air temperature, the outside air temperature detecting means can detect the outside air temperature in addition to the body surface temperature detecting means. it can. The data reading means reads the body surface temperature detection data and the outside air temperature detection data together at a constant time interval, and the storage means reads the body surface temperature information based on the body surface temperature detection data and the outside air temperature information based on the outside air temperature detection data. Therefore, even when the body surface temperature information fluctuates due to the influence of the outside air, the body surface temperature information can be corrected using the outside air temperature detection data.
  In addition, since the data reading means is configured to read the body surface temperature detection data and the outside air temperature detection data at regular time intervals from the set start time to the end time, the storage means includes these Temperature information at a plurality of times based on the detected data can be stored. Further, since the data reading means includes a timer, the time when the detection data is read can be stored together with the detection data.
  Further, the thermal equilibrium state determination means, for example, has a small temperature change in the casing or the like when the sum of squares of the temporal fluctuation width of the body surface temperature information and the temporal fluctuation width of the outside air temperature information is smaller than a predetermined determination value. Judged to be in thermal equilibrium. Thereby, the representative temperature candidate extracting means extracts the corrected temperature information at this time as a representative temperature candidate. Since the representative temperature selection means selects the highest temperature among the representative temperature candidates, the corrected temperature information of the thermal equilibrium state in which the casing, the body surface temperature detection means, etc. are sufficiently warmed by the user's body temperature, for example, It can be specified as a representative temperature during sleeping. As a result, the representative temperature can accurately correspond to the body temperature of the user, and the reliability of the representative temperature can be improved.
[0015]

[0016]
  As a result, the body surface temperature detecting means and the outside air temperature detecting means can be arranged on the opposite side across the casing, so that when the body surface temperature detecting means contacts the user's body surface, the outside air temperature detecting means is The user can be surely in a non-contact state with respect to the user's body surface, and the outside temperature can be accurately detected by the outside temperature detecting means. Further, since the outside air temperature detecting means is covered by the clip, the outside air temperature detecting means can be prevented from coming into contact with the user's arm or the like when turning over, and the reliability of the outside air temperature detection data can be improved. . Further, since the outside air temperature detecting means can be protected by the clip, the outside air temperature detecting means can be prevented from being damaged, and the reliability and durability can be improved.
[0017]
  Claim3In the invention, the storage means records the difference value between the preset reference temperature value and the body surface temperature detection data value as body surface temperature information, and the difference value between the reference temperature value and the outside air temperature detection data value Is recorded as outside air temperature information.
[0018]
  In this case, for example, the fluctuation range of body temperature based on menstruation or the like is about ± 0.3 ° C. at the maximum. Also, considering the effects of environmental changes and fluctuations in body surface temperature during the day, the temperature of the body surface detected by the body surface temperature detecting means varies by about ± several degrees with respect to the average value. Is seen. Further, since the outside air temperature detection means is also warmed by the body surface temperature of the user through the casing, the outside air temperature detection data by the outside air temperature detection means becomes a value close to the body surface temperature detection data by the body surface temperature detection means.
[0019]
  For this reason, for example, by setting a reference temperature value as the average body surface temperature of the user, only the fluctuation of the body temperature can be stored as body surface temperature information or outside air temperature information. As a result, compared with the case where all body temperature information is stored, for example, 36.40 ° C., the amount of temperature information to be stored can be reduced, the capacity of a storage element such as a RAM is reduced, and the entire apparatus is downsized. The cost can be reduced and the amount of body surface temperature information and outside air temperature information to be stored can be increased.
[0020]
  Claim4In the invention, the reference temperature numerical value can be updated from the outside. Thereby, since the reference temperature numerical value can be set according to the individual difference of the average body surface temperature, even when the average value of the body surface temperature is different for each user, only the fluctuation of the body temperature is stored as temperature information, The amount of temperature information can be reduced.
[0021]

  With this configuration, the body surface temperature information and the outside air temperature information stored in the storage means of the body temperature information terminal device are acquired using the temperature information acquisition means, and these body surface temperature information and the analysis means are used. The outside air temperature information can be analyzed, and the analysis result output means can be used to output analysis results such as a woman's menstrual cycle and female hormone balance information visually or audibly to an external mobile phone or the like.
[0025]
  Further, since the analysis means analyzes the body surface temperature information and the outside air temperature information, for example, even when the body surface temperature information fluctuates due to the influence of the outside air, the analysis means uses the outside air temperature information to detect the body surface temperature. Information can be modified. Furthermore, the analysis means can determine whether or not the casing or the like is in a thermal equilibrium state with little temperature change using the body surface temperature information and the outside air temperature information. For this reason, the analysis means can correct the body surface temperature information when the heat equilibrium state is reached using the body surface temperature information and the outside air temperature information, for example, the menstrual cycle of the woman and the female hormone balance information. It can be analyzed accurately.
  At this time, for example, when the sum of squares of the temporal fluctuation width of the body surface temperature information and the temporal fluctuation width of the outside air temperature information is smaller than a predetermined determination value, the thermal equilibrium state determination means changes the temperature of the casing or the like. Determine that there is little thermal equilibrium. Thereby, the representative temperature candidate extracting means extracts the corrected temperature information at this time as a representative temperature candidate. Since the representative temperature selection means selects the highest temperature among the representative temperature candidates, the corrected temperature information of the thermal equilibrium state in which the casing, the body surface temperature detection means, etc. are sufficiently warmed by the body temperature of the user, for example, It can be specified as a representative temperature during sleeping, and the representative temperature can be accurately matched to the body temperature of the user. As a result, the analysis means can accurately analyze, for example, a woman's menstrual cycle, female hormone balance information, and the like using the representative temperature thus identified.

[0052]
  BookThe body temperature information terminal device 1 according to the embodiment has the above-described configuration. Next, the operation for specifying the representative temperature is illustrated.1Or figure12Will be described with reference to FIG.
[0053]
  First, the user H has an input unit7Start time t1, end time t2, time interval Δt, reference temperature numerical value T0, and the like. Next, the user H inputs the input unit7After starting the representative temperature identification program, etc. with the button switch, etc.,bodyThe casing 2 is sandwiched between the abdomen A and the underwear B in a state where the cover member 4A of the surface temperature detection unit 4 is in contact with the abdomen A, and the casing 2 is fixed to the underwear B using the clip 3. In this state, the user H goes to bed. At this time, the control unit9The storage unit10From figure11The representative temperature specifying program shown in FIG.
[0054]
  First, in step 1, the control unit9The timer11It waits in the state as it is until the time according to reaches the start time t1 such as midnight. And timer11When the time by reaches the start time t1, the control unit9Reads, for example, body surface temperature detection data Ts corresponding to the measured temperature from the body surface temperature detection unit 4 (temperature measuring element 4B) at every preset time interval Δt of about 10 minutes, and an outside air temperature detection unit5To read outside temperature detection data Ta corresponding to the measured temperature. At this time, the control unit9Calculates the difference between the temperature value of the read detection data Ts, Ta and the reference temperature value T0 set to the body surface temperature of the average abdomen A of the user H, and the difference values ΔTs, ΔTa are calculated. Storage10Are stored in sequence.
[0055]
  And control unit9After repeating such body temperature and outdoor temperature measurement operations at time intervals Δt, the timer11When the time according to reaches the end time t2, the measurement operation is ended and the routine proceeds to step 2. Thus, when the user H gets up, the storage unit10On the other hand, the difference values ΔTs and ΔTa for each constant time interval Δt from the start time t1 to the end time t2 are automatically stored.
[0056]
  Next, in Step 2, the control unit9The storage unit10Using the difference value ΔTs depending on the body surface temperature stored in the table, the measured temperature of the body surface (body surface temperature detection data Ts) is considered to be a value based on the daily body temperature (for example, 33 ° C. to 38 ° C. ) Or not. The body surface temperature detection data Ts that do not belong to this range is removed as invalid data and is not used in the subsequent calculations.
[0057]
  Next, in Step 3, the body surface temperature detection data Ts (difference value ΔTs) is corrected using the outside air temperature detection data Ta (difference value ΔTa), and the outside air temperature is obtained as a corrected body surface temperature Ts ′ (correction temperature information). The body surface temperature when a predetermined constant value TA (for example, TA = 33 ° C.) is obtained is calculated.

When the heat flux q is removed from the equation (1), as shown in the equation (2), the body temperature Ti can be calculated using the body surface temperature detection data Ts and the outside air temperature detection data Ta.
[0061]
[Expression 2]

[0062]
  Next, assuming that the outside air temperature Ta is a predetermined constant temperature TA, and the body surface temperature at this time is the corrected body surface temperature Ts', the body temperature Ti is expressed by the following equation (3) as in the equation (2). It can be expressed as The constant K can be obtained in advance as an optimum value based on various physical property data, clinical data, and the like.
[0063]
[Equation 3]

[0064]
  Based on the equation (3), the body surface temperature (corrected body surface temperature Ts ′) when the outside air temperature is a constant value TA can be calculated by the following equation (4).
[0065]
[Expression 4]

[0066]
  As a result, the corrected body surface temperature Ts ′ when the external environment is made constant can be calculated by using the equations of Equations 2 and 4.12reference).
[0067]
  Next, in step 4, the time fluctuation width ΔS (ΔS = Ts [i] −Ts [i−1]) of the body surface temperature detection data Ts (difference value ΔTs) for each time interval Δt is calculated, A temporal variation width ΔA (ΔA = Ta [i] −Ta [i−1]) of the outside air temperature detection data Ta (difference value ΔTa) is calculated. That is, the difference between the i-th detection data Ts [i], Ta [i] at the time of measurement and the (i-1) -th detection data Ts [i-1], Ta [i-1] is expressed as a temporal variation width ΔS. , ΔA.
[0068]
  Next, in step 5, the sum of squares of the temporal fluctuation widths ΔS and ΔA calculated in step 4 is expressed as a temperature equilibrium index β (see FIG.12The temperature balance index β is used to determine whether or not the temperature equilibrium index β is smaller than a predetermined determination value β0 close to zero (for example, β0 = 0.01 to 0.09).
[0069]
[Equation 5]

[0070]
  And in step 5,12As shown in FIG. 5, at the time when the temperature equilibrium index β is smaller than the determination value β0 (β <β0), the terminal device 1 determines that the temperature equilibrium is small and the temperature equilibrium index β is equal to or greater than the determination value β0 ( At the time when β ≧ β0), the terminal device 1 determines that it is in a thermal non-equilibrium state, for example, during heating or cooling.
[0071]
  Next, in step 6, the corrected body surface temperature Ts 'at the time determined to be in the thermal equilibrium state in step 5 is extracted as a representative temperature candidate, and the corrected body surface temperature Ts' at the time determined to be in the thermal non-equilibrium state. Is excluded from the representative temperature candidates.
[0072]
  Next, in step 7, the representative temperature candidate selected from the plurality of representative temperature candidates (corrected body surface temperature Ts ′) extracted in step 6 is selected as the representative temperature Td. And control unit9Displays the representative temperature Td from the start time t1 to the end time t2 (representative temperature Td on the day of sleep)6And display the representative temperature Td10And the process proceeds to step 8 to end the representative temperature specifying program.
[0073]
  Finally, the user H, as in the first embodiment,12External information devices such as mobile phones, mobile terminals, computers13To relay cable14Connect through. At this time, the relay cable14In the middle of the memory10Data such as differential values ΔTs, ΔTa, representative temperature Td, etc.13Mediation device that converts data into readable data15Is connected. As a result, the storage unit10The difference value ΔTs, ΔTa, representative temperature Td, etc. for one day stored in13Can be transmitted to external information equipment13Itself or the external information device13The difference values ΔTs, ΔTa are analyzed using an external server computer or the like (not shown) connected via the computer, and the physical condition of the user H is determined based on the fluctuation of the corrected body surface temperature Ts ′ during sleep. It can be performed.
[0074]
  Further, for example, an external server computer or the like can store a representative temperature Td corresponding to the basal body temperature of the user H for several days or months. As a result, it is possible to measure changes in basal body temperature (representative temperature Td) over several days or months using an external server computer, etc., so information such as the menstrual cycle based on changes in basal body temperature can be accurately obtained. Analyze and communicate to user H.
[0075]
  Storage unit10The difference values ΔTs, ΔTa, the representative temperature Td, etc. stored in the table are not always external information devices every day.13It is not necessary to output to the storage unit10The difference information ΔTs, ΔTa, etc. for several days according to the capacity of the external information device13It is good also as a structure which outputs to. Thus, by outputting the difference values ΔTs, ΔTa, etc. for a plurality of days, the external information device13On the other hand, it is possible to save the trouble of outputting the difference values ΔTs, ΔTa, etc.
[0076]
  Moreover, in this Embodiment, the control unit in the terminal device 19The representative temperature Td is specified by the external information device that has received the difference values ΔTs and ΔTa.13Alternatively, the representative temperature Td may be specified using an external server computer or the like. In this case, the control unit9In contrast, the processing burden associated with the specification of the representative temperature Td can be reduced.
[0077]
  Thus, in the present embodiment, the body surface temperature detection data T by the body surface temperature detection unit 4 is applied to the casing 2 that can be always attached to the body. s And outside temperature detection data T by outside temperature detector 5 a Is provided at a constant time interval Δt, and the detection data T read by the control unit 9 is provided. s , T a Difference value ΔT based on s , ΔT a Therefore, the user H can go to bed with the casing 2 attached to the body, and the body temperature during sleeping can be set so that the body temperature is more stable than when waking up. Can be measured.
[0078]
  In addition, the control unit 9 detects the body surface temperature at a constant time interval Δt of, for example, about 5 minutes. Body surface temperature detection data T by the detector 4 s And outside temperature detection data T by outside temperature detector 5 a And these detection data T s , T a Reference temperature value T calculated based on 0 Difference value ΔT s , ΔT a Is stored in the storage unit 10, so that the difference value ΔT corresponding to the body temperature during sleep s , ΔT a By using this, the body temperature of the user H can be accurately obtained, and the fluctuation range of the basal body temperature and the menstrual cycle can be accurately grasped.
[0079]
  Moreover, since the clip 3 is provided in the casing 2, the clip 3 can be easily attached to the underwear that comes into contact with the skin, and the casing 2 can be covered with the underwear. As a result, the body surface temperature detector 4 can be brought into contact with the abdomen A, which is close to the internal organs, in which fluctuations in body temperature are easily reflected, and is not easily affected by fluctuations in outside air temperature because it is covered with underwear, etc. The temperature of the abdomen kept warm by the underwear can be measured, and the influence of the outside air temperature can be reduced by the underwear, so that the temperature of the body surface can be detected accurately.
[0080]
  Further, when the casing 2 is attached to the abdomen A, the casing 2 is less likely to be displaced from the measurement site particularly during sleeping, so that the measurement error due to the displacement is also reduced. And the detection accuracy can be increased.
[0081]
  Reference temperature value T 0 Since it has a configuration that can be updated from the outside, the reference temperature value T according to individual differences in the average body surface temperature 0 Even when the average value of the body surface temperature is different for each user H, only the fluctuation of the body temperature is stored as the body surface temperature information, and the data amount of the body surface temperature information can be reduced.
[0082]
  The body surface temperature detection unit 4 is provided between the cover member 4A protruding from the casing 2, the temperature measuring element 4B covered by the cover member 4A, and the temperature measuring element 4B and the cover member 4A. Since the cover member 4A protruding from the casing 2 can be easily brought into contact with the body surface, the temperature of the body surface is transferred to the temperature measuring element 4B through the cover member 4A and the heat conduction sheet 4C. It can be transmitted with low loss, and the temperature of the body surface can be accurately detected using the temperature measuring element 4B.
[0083]
  AlsoIn the present embodiment, the outside air temperature detection unit that detects the temperature of the outside air on the back side of the casing 25In addition to detecting the temperature of the body surface by the body surface temperature detector 4, the outside air temperature detector5Can detect the temperature of the outside air. And storage part10Stores the difference value ΔTs based on the body surface temperature detection data Ts and the difference value ΔTa based on the outside air temperature detection data Ta. Therefore, even if the difference value ΔTs varies due to the influence of the outside air, the outside air temperature detection data Ta ( The difference value ΔTs can be corrected using the difference value Ta).
[0084]
  In particular, in the present embodiment, the body surface temperature detection data Ts having a constant external environment is calculated as the corrected body surface temperature Ts ′ using the outside air temperature detection data Ta (difference value ΔTa). Even when traveling from a warm area such as Okinawa to a cold area such as Hokkaido due to travel, etc., it is not affected by changes in the external environment, and an accurate corrected body surface temperature Ts' is calculated and used. Thus, an accurate representative temperature Td corresponding to the basal body temperature can be specified.
[0085]
  Control unit9Uses the temporal variation width ΔS of the body surface temperature detection data Ts and the temporal variation width ΔA of the outside air temperature detection data Ta to determine whether the temperature of the casing 2 or the like is in a thermal equilibrium state with little temperature change. Since the corrected temperature information Ts ′ of only the state is extracted as a representative temperature candidate, and the representative temperature candidate having the highest temperature is selected as the representative temperature Td, the casing 2 and the body surface temperature are selected according to the body temperature of the user H. The corrected temperature information Ts ′ in the thermal equilibrium state in which the detection unit 4 or the like is sufficiently warmed can be specified as the representative temperature Td on the day of going to bed. For this reason, since the representative temperature Td can be accurately matched to the body temperature (basal body temperature) of the user, it is possible to accurately grasp information such as the menstrual cycle based on changes in the basal body temperature using the representative temperature Td. it can.
[0086]
  In addition, the body surface temperature detector 4 is disposed on the front side of the casing 2 and the outside air temperature detector5Is disposed on the back side of the casing 2 so that the body surface temperature detection unit 4 and the outside air temperature detection unit sandwich the casing 2 therebetween.5When the body surface temperature detection unit 4 comes into contact with the body surface (skin) of the user H, the outside air temperature detection unit5Can be reliably brought into a non-contact state with respect to the body surface of the user H5Can accurately detect the outside air temperature.
[0087]
  Furthermore, the outside air temperature detector5Since the cover is covered with the clip 3, the outside temperature detector5Can be prevented by the clip 3 and the reliability of the outside air temperature detection data Ta can be improved. In addition, the clip 3 is used to detect the outside air temperature.5Because it can protect the outside temperature detector5Can be prevented, and reliability and durability can be improved.
[0088]
  Control unit9Reads the detection data Ts from the body surface temperature detector 4 from the start time t1 to the end time t2, and the outside air temperature detector5Because it is configured to read the detection data Ta from the control unit9Can read the detection data Ts, Ta at regular time intervals Δt from a preset start time t1 such as midnight to an end time t2 before waking up,10Can automatically store a plurality of body surface temperature information (difference value ΔTs) and outside air temperature information (difference value ΔTa) while sleeping based on the detection data Ts, Ta. In addition, the control unit9Is a timer11Therefore, the time when the detection data Ts and Ta are read can be stored together with the detection data Ts and Ta.
[0089]
  The storage unit10Is configured to record the difference value ΔTs between the reference temperature value T0 and the detection data Ts as body surface temperature information, and to record the difference value ΔTa between the reference temperature value T0 and the detection data Ta as outdoor temperature information. Therefore, for example, by setting the reference temperature numerical value T0 to the average body surface temperature of the abdomen A of the user H, only the fluctuation of the body temperature while sleeping can be stored in the body surface temperature information and the outside air temperature information. it can. As a result, the data volume of body surface temperature information and outside air temperature information to be stored can be reduced, the capacity of the storage element such as RAM can be reduced, the entire apparatus can be reduced in size and cost, and the stored body surface temperature information and The outside air temperature information can be increased.
[0090]
  Further, the casing 2 includes a storage unit.10Connection unit for outputting body surface temperature information (difference value ΔTs) and outside air temperature information (difference value ΔTa) stored in the outside12Since the connection is provided12Through external information equipment13Body surface temperature information and outside air temperature information can be output to the external information device.13By connecting to the network, the body surface temperature information and the outside air temperature information can be analyzed using an external server computer or the like, and the user can receive various services.

And an external information processing device31Analyzes the body surface temperature information output from the terminal device 1 and outputs the analysis result to the external information device.13And the like, and functions as temperature information acquisition means, analysis means, and analysis result output means.
[0101]
  The body temperature information processing system according to this embodiment has the above-described configuration, and the operation thereof will be described next.
[0102]
  First, the user H uses the body temperature information terminal device 1 in which body temperature information for one day or several days is stored as a communication mediating device.25External information equipment through etc.13Connect to. User H is an external information device.13The network network32External information processing device via31Connect to external information equipment13To external information processing equipment31Transmits a signal instructing to analyze body surface temperature information.
[0103]
  As a result, the external information processing apparatus31External information equipment13Coil member for magnetic induction as temperature information output means from the terminal device 1 in response to an instruction from24To obtain body surface temperature information and outside air temperature information, etc.1'sControl unit according to embodiment9The body temperature (representative temperature Td) corresponding to the basal body temperature is calculated by analyzing the acquired body surface temperature information and outside air temperature information by performing almost the same arithmetic processing as. At this time, information on the body temperature of the user H is preliminarily stored, for example, for about three months.31It is possible to know changes in basal body temperature from day to day by memorizing them. For this reason, an external information processing device31Can obtain analysis results such as a woman's menstrual cycle and female hormone balance information based on the basal body temperature of the day when the acquired body surface temperature information is measured and the basal body temperature fluctuations for several days to several months.

Thereby, the user H can recognize the basal body temperature and the menstrual cycle of the day, and can use the analysis result for physical condition management and health management.
[0105]
  Thus, in the present embodiment, the first embodiment is also used.State andAlthough the same effect can be obtained, in the present embodiment, since the body temperature information terminal device 1 according to the present invention is used, compared with the case where other thermometers are used, it is not unreasonable over a long period of time. And body temperature (body surface temperature information) can be measured accurately. The body surface temperature information thus measured is32External information processing device connected to31Therefore, the terminal device 1 can be used only for measuring and storing body temperature, can be reduced in size and weight, and can be always worn while sleeping. On the other hand, external information processing device31Uses the body surface temperature information and the outside air temperature information recorded by the terminal device 1, so that the fluctuation of the basal body temperature can be accurately calculated, and the analysis result such as the menstrual cycle is more accurate than the conventional technique.

  Further, in each of the above-described embodiments, it has been described that the terminal device 1 is mainly worn by an adult female user. However, the present invention is not limited to this. For example, the terminal device 1 may be mounted on a newborn, an infant, an elderly caregiver, an animal, or the like whose body temperature is difficult to measure. As a result, changes in body temperature of newborns, etc. can be grasped, health status etc. can be discriminated, physical condition changes due to sudden fluctuations in body temperature at the time of illness, and death estimated time due to unexpected situations can be grasped Can also help.
[0109]
【The invention's effect】
  As described in detail above, according to the first aspect of the present invention, the casing that can be always attached to the body is provided with the data reading means for reading the body surface detection data by the body surface temperature detecting means at regular time intervals, Since the storage means for storing the body surface temperature information based on the body surface detection data read by the data reading means is provided, the user can go to bed with the casing attached to the body, Compared to this, it is possible to measure the body temperature during sleeping when the body temperature is stable. The data reading means reads the body surface temperature detection data by the body surface temperature detection means at regular time intervals, and the storage means stores the body surface temperature information based on the detection data. By using the corresponding body surface temperature information, the body temperature corresponding to the basal body temperature of the user can be accurately obtained, and the fluctuation range of the basal body temperature and the menstrual cycle can be accurately grasped.
[0110]
  That is, according to the present invention, by setting the time to be measured in the terminal at midnight or early morning when sleeping, the desired time displacement is already recorded inside at any time awakened the next morning. Therefore, it is very easy to track and record daily fluctuations in basal body temperature over several months, and a clue to know a woman's menstrual cycle and hormonal balance rhythm can be obtained easily. As a result, all women from puberty to menopause can easily use, and basal body temperature measurement, which has not been used much other than for the purpose of pregnancy and contraception, health management using female hormone balance information Can be an effective means of.
[0111]
  Further, since the casing is provided with the outside air temperature detecting means for detecting the outside air temperature, the outside air temperature detecting means can detect the outside air temperature in addition to the body surface temperature detecting means. it can. The data reading means reads the body surface temperature detection data and the outside air temperature detection data together at a constant time interval, and the storage means reads the body surface temperature information based on the body surface temperature detection data and the outside air temperature information based on the outside air temperature detection data. Therefore, even when the body surface temperature information fluctuates due to the influence of the outside air, the body surface temperature information can be corrected using the outside air temperature detection data.
  In addition, since the body surface temperature information with a constant external environment is calculated as the corrected temperature information using the outside air temperature information, for example, even when the user moves to a place where the outside air temperature is significantly different due to travel etc., the change in the outside environment Therefore, it is possible to calculate accurate corrected temperature information without being influenced by, and to specify an accurate representative temperature corresponding to the basal body temperature using this corrected temperature information.
  The thermal equilibrium state determination means determines whether the casing or the like is in a thermal equilibrium state using the temporal variation width of the body surface temperature information and the temporal variation width of the outside air temperature information, and corrects the temperature only in the thermal equilibrium state. Since information is extracted as representative temperature candidates and the highest temperature among these representative temperature candidates is selected as the representative temperature, the casing, body surface temperature detection means, etc. are sufficiently warmed by the user's body temperature. The corrected temperature information of the state can be specified as the representative temperature on the day of going to bed. For this reason, since the representative temperature can accurately correspond to the body temperature (basal body temperature) of the user, information such as the menstrual cycle based on the change in the basal body temperature can be accurately grasped using the representative temperature.
[0115]
  Claim2According to the invention, the body surface temperature detecting means can contact the body surface.In stateArranged on the front side of the casing, the outside air temperature detection meansIn a state covered with clipsSince it is arranged on the back side of the casing, the body surface temperature detecting means and the outside air temperature detecting means can be arranged on the opposite side across the casing, and the body surface temperature detecting means contacts the user's body surface. When this is done, the outside air temperature detecting means can be reliably brought into non-contact with the user's body surface, and the outside air temperature detecting means can accurately detect the outside air temperature.
[0116]
  Further, since the outside air temperature detecting means is covered with the clip, it is possible to prevent the outside air temperature detecting means from coming into contact with the arm or the like when turning over, and the reliability of the outside air temperature detection data can be improved. Further, since the outside air temperature detecting means can be protected by the clip, the outside air temperature detecting means can be prevented from being damaged, and the reliability and durability can be improved.
[0117]
  Claim3According to the invention, the difference value between the reference temperature value and the body surface temperature detection data value is recorded as body surface temperature information in the storage means, and the difference value between the reference temperature value and the outside air temperature detection data value is recorded as the outside air. Since it is configured to record as temperature information, for example, by setting the reference temperature value to the average body surface temperature of the user, only the fluctuation in body temperature (about ± 3.0 ° C) during measurement is detected. Information or outdoor temperature information can be stored. As a result, for example, compared to storing an absolute value of body temperature of about 36.40 ° C., the data amount of each temperature information to be stored can be reduced, the capacity of a storage element such as a RAM is reduced, and the entire apparatus is downsized. The cost can be reduced and the stored body surface temperature information and outside air temperature information can be increased.
[0118]
  Claim4According to the invention, since the reference temperature value can be updated from the outside, the reference temperature value can be set according to the individual difference of the average body surface temperature, and the average value of the body surface temperature is different for each user. Even if they are different, only the fluctuation of the body temperature is stored as the temperature information, and the data amount of the temperature information can be reduced.
[0119]
  ClaimOf 5According to the invention, since the casing is provided with the temperature information output means for outputting the body surface temperature information and the outside air temperature information stored in the storage means to the outside, the body surface temperature information is supplied to the external information device via the temperature information output means. And the outside air temperature information can be output, and by connecting the external information device to the network, the body surface temperature information and the outside air temperature information can be analyzed using an external server computer or the like. The user can receive various services based on the temperature information.
[0120]
  Claim6According to the invention, the storage means of the body temperature information terminal device stores the body surface temperature information and the outside air temperature information, and the body surface temperature stored in the storage means of the body temperature information terminal device using the temperature information acquisition means. Information and outside air temperature information are obtained, and these body surface temperature information and outside air temperature information are analyzed using the analysis means. Therefore, using the analysis result output means, for example, women's menstrual cycle and female hormone balance information Can be output visually or audibly to an external mobile phone or the like.
[0121]
  Further, since the analysis means analyzes the body surface temperature information and the outside air temperature information, for example, even when the body surface temperature information fluctuates due to the influence of the outside air, the analysis means uses the outside air temperature information to detect the body surface temperature. Information can be corrected, and for example, a woman's menstrual cycle, female hormone balance information, and the like can be accurately analyzed.
  The thermal equilibrium state determination means determines whether the casing or the like is in a thermal equilibrium state by using the temporal fluctuation width of the body surface temperature information and the temporal fluctuation width of the outside air temperature information, and the representative temperature candidate extraction means The condition correction temperature information is extracted as a representative temperature candidate, and the representative temperature selecting means selects the highest temperature among the representative temperature candidates, so that the casing and body surface temperature are detected based on the user's body temperature. The corrected temperature information of the thermal equilibrium state in which the means or the like is sufficiently warmed can be specified as, for example, the representative temperature during sleeping, and the representative temperature can be accurately matched to the body temperature (basal body temperature) of the user. As a result, the analysis means can accurately analyze, for example, a woman's menstrual cycle, female hormone balance information, and the like using the representative temperature thus identified.
[0124]
  In this case, the claim7As in the invention, the usage fee may be collected from the user who has acquired the analysis result by the analysis result output means.
