Description

【０００１】
【発明の属する技術分野】
本発明は、女性の生理状態を把握できる機能を備えた婦人体温計に関するものである。
【０００２】
【従来の技術】
従来、生理開始日入力手段に入力された生理開始日の間隔を各生理周期に対応する生理周期日数として、その生理周期日数の平均日数を最新生理開始日に加算した日を次回生理開始日と予測して報知する婦人体温計があった。また、低温期から高温期への移行が確認できた時点（高温期と判定される基礎体温が３日連続した時点）で、その日に１２日加算した日（高温期初日から数えて１４日に該当）を次回生理開始日と予測して報知する婦人体温計があった（特開昭６２−１８３８０７）。
【０００３】
【発明が解決しようとする課題】
女性にとっては、将来の生理開始日を事前に正しく知るということは事前の準備や今後の行動の予定をたてる上で重要である。
【０００４】
ところが、女性の生理状態は非常にデリケートであり、生理周期日数のかなり安定している人でもストレス等で容易に生理周期日数が乱れて通常の生理周期日数より短くなったり長くなったりすることが起こる。特に、現代は女性がストレスにさらされる機会が増えており、生理周期日数が乱れる場合が頻繁に起こりやすい。
【０００５】
このような周期日数の乱れに対して、単純に平均をとる前記第１の婦人体温計では、せっかく周期日数の安定している人でも、いくつかの乱れた周期日数によって平均周期日数が乱されて次回生理開始日の予測精度が落ちてしまっていた。
【０００６】
また、周期日数が乱れた場合は、低温期の日数が変動するだけで、高温期の日数はほぼ一定日数と言われているので、前記第２の婦人体温計では、前記第１の体温計程には乱れた周期日数の影響は受けないものの、高温期の日数を１４日と固定しているので個人差には対応できない。高温期日数１４日というのは標準ではあるが、現実には１４日を中心に１２〜１６日程度であり、生理機能の安定しない若年層や更年期あたりの女性ではもう少し長いまたは短い。この様な個人差には対応できないため、やはり予測精度が落ちるものである。
【０００７】
本発明はこのような従来の婦人体温計が有している課題を解決するもので、将来の生理開始日の予測精度を向上した婦人体温計を実現することを目的としている。
【０００８】
【課題を解決するための手段】
前記目的を達成するための本発明の第１の手段は、基礎体温を測定するための体温測定手段と、各生理周期の初日を入力するための生理開始日入力手段と、前記体温計測部で測定された基礎体温と前記生理開始日入力手段で入力された生理開始日等を記憶するための記憶手段と、カレンダー機能を有して前記記憶手段に記憶されたデータをもとに将来の生理開始日を予測するための生理開始日予測手段とを有し、前記生理開始日予測手段は、記憶手段に記憶している生理開始日の間隔を各生理周期に対応する生理周期日数として、生理周期日数の平均との差が所定日数以上ある生理周期と各生理周期内での高温期平均体温と低温期平均体温の差が所定値未満の生理周期を除外して残りの有効生理周期に対して有効生理周期日数平均を算出し、将来のｎ周期先の生理開始日を（最新生理開始日＋ｎ×有効生理周期日数平均）と予測するように構成し、異常な生理周期を除外して将来の生理開始日の予測精度を向上した婦人体温計としている。
【０００９】
また本発明の第２の手段は、前記生理開始日予測手段は、有効生理周期の数が対象とする全生理周期の数の所定割合以上ある時に将来の生理開始日を予測するるように構成し、さらに将来の生理開始日の予測精度を向上した婦人体温計としている。
【００１０】
本発明の第３の手段は、前記生理開始日予測手段は、前記体温測定手段で測定された基礎体温によって低温期から高温期への移行を判断できた時点で、高温期の初日前日に前記記憶手段に記憶している各生理周期の基礎体温から算出される高温期平均日数を加えた日を次回の生理開始日と修正予測するように構成し、現生理周期における低温期の変動影響を除外してかつ個人差に応じた将来の生理開始日の予測精度を向上した婦人体温計としている。
【００１１】
本発明の第４の手段は、前記記憶手段に記憶している基礎体温と生理開始日から生理開始日とその前日との体温差の平均を算出する体温差算出手段を備え、前記生理開始日予測手段は、予測した次回生理開始日を越えても前記生理開始日入力手段で生理開始日入力がなかった場合は、前記体温測定手段で測定された基礎体温が前日の基礎体温と前記体温差算出手段で算出された体温差以上あった時にその日を次回の生理開始日と修正予測するように構成し、予測した次回生理開始日を越えても前記生理開始日入力手段で生理開始日入力がなかった場合即ち周期日数の長い生理周期でも個人差に応じた将来の生理開始日の予測精度を向上した婦人体温計としている。
【００１２】
本発明の第５の手段は、報知手段を備え、前記報知手段は、前記生理開始日入力手段に生理開始日入力がある毎に、または前記生理開始日予測手段が修正予測をする毎に、将来の生理開始日を報知するように構成し、使用者が常に予測精度の良い将来の生理開始日を認識できる婦人体温計としている。
【００１３】
本発明の第６の手段は、記憶手段限定手段を備え、前記生理開始日予測手段が将来の生理開始日を予測するために用いるデータは、前記記憶手段限定手段によって現在の日から最新の１年以内の所定期間内のものだけに限定されたデータとするように構成し、最近の生理周期変動に対応して将来の生理開始日の予測精度を向上した婦人体温計としている。
【００１４】
【発明の実施の形態】
（実施の形態１）
以下本発明の第１の実施形態について説明する。図１は本実施形態の婦人体温計の構成を示すブロック図である。
【００１５】
婦人体温計の本体１（以下単に本体１と称する）は、体温測定手段２と、生理開始日入力手段３と、記憶手段４と、生理開始日予測手段５とを備えている。
体温測定手段２はサーミスタで構成し、生理開始日入力手段３は押しボタンスイッチで構成し、生理開始日予測手段５はマイクロコンピュータによって構成しており、生理開始日予測手段５はカレンダー機能を有している。
【００１６】
使用者は、毎朝１回起床時に布団に入ったままの状態で、体温測定手段２を舌下に入れて安静時の基礎体温を測定する。また、生理時にはその初日を生理開始日として生理開始日入力手段３で入力する。このように測定された基礎体温や入力された生理開始日は、日時がわかるように記憶手段４に記憶される。生理開始日予測手段５は、記憶手段４に記憶されたデータをもとに次回以降の将来の生理開始日を予測する。
【００１７】
以下本実施形態の生理開始日予測手段５の動作について図２のフローチャートにより説明する。
【００１８】
生理開始日予測手段５は、まず、記憶手段４に記憶した生理開始日の間隔から各生理周期について生理周期日数を算出する。例えば１番古い生理開始日が１９９８年１月１日で２番目に古い生理開始日が１９９８年１月２９日であれば、第１生理周期の周期日数は２８日になる。以下記憶手段４に記憶した全生理周期について生理周期日数を算出し（ステップ１）、生理周期日数平均を算出する（ステップ２）。次に、記憶手段４に記憶した全生理周期について、各々の生理周期日数と算出した生理周期日数平均との差を求めて差が４日以上の場合はその生理周期の生理周期日数は無効とし、差が３日以下の場合はさらにその生理周期の高温期体温平均と低温期体温平均の差をチェックする。即ち、差が０．３℃未満の場合はその生理周期の生理周期日数を無効とし、差が０．３℃以上の場合はその生理周期日数を有効として、有効生理周期を決定する（ステップ３〜ステップ６）。決定した有効生理周期について生理周期日数の平均を算出する（ステップ７）。最後に、（最新生理開始日＋ｎ×有効生理周期日数平均）を算出し、将来のｎ周期先の生理開始日を予測する（ステップ８）。
【００１９】
なお、本実施形態では、将来の生理開始日を予測するためのデータとして、記憶手段に記憶した全生理周期を用いたが、記憶手段に記憶した一部の生理周期を対象としても良い。また、生理周期日数との差の所定値を３日、高温期体温平均と低温期体温平均との差の所定値を０．３℃としたが、標準偏差等の値を用いても良い。さらに、本実施形態では生理開始日の入力があった時点で予測動作を行うようにしたが、次回生理開始日までの間ならいつ予測を行ってもかまわない。
【００２０】
以上のように本実施形態によれば、異常な生理周期を除外して将来の生理開始日の予測精度を向上した婦人体温計を提供することができる。
【００２１】
（実施の形態２）
続いて本発明の第２の実施形態について説明する。本実施形態の婦人体温計の構成を示すブロック図は第１の実施形態と同じ図１である。
【００２２】
以下本実施形態の生理開始日予測手段５の動作について図３のフローチャートにより説明する。第１の実施形態と同一機能を持つものは同一ステップ記号を用いている。生理開始日予測手段５が各生理周期が有効か無効か決定するまでは、第１の実施形態と同様である。有効生理周期が決定されると、有効生理周期数が対象の全生理周期数の２／３以上あるかどうかチェックする（ステップ９）。全生理周期数の２／３以上ある時のみ、次回以降の将来の生理開始日を予測し（ステップ１０〜ステップ１１）、２／３未満の時は予測を行わない。例えば、対象とする全生理周期数が１０で、その内で有効生理周期数が７以上ある時は予測を行うが、有効生理周期数が７未満の時は予測を行わない。
【００２３】
なお、本実施形態では、有効生理周期数が対象の全生理周期数の２／３以上の時のみ生理開始日予測手段が予測を行うようにしたが、割合は予測精度に合わせて任意の割合に設定してかまわない。
【００２４】
以上のように本実施形態によれば、さらに将来の生理開始日の予測精度を向上した婦人体温計を提供することができる。
【００２５】
（実施の形態３）
続いて本発明の第３の実施形態について説明する。本実施形態の婦人体温計の構成を示すブロック図は第１の実施形態と同じ図１である。
【００２６】
以下本実施形態の生理開始日予測手段５の動作について図４のフローチャートにより説明する。まず、生理開始日予測手段５は、生理開始日入力手段３に生理開始日が入力された時点で、第１の実施形態及び第２の実施形態同様、有効生理周期を決定し、生理開始日の予測を行う(ステップ１２）。この予測ができた場合についてのみ、生理開始日予測手段５は以下の動作を行う（ステップ１３）。即ち、まず有効生理周期について高温期平均日数を求める（ステップ１４）。次に、体温測定手段２で測定した基礎体温が低温期から高温期へ移行したかどうかチェックする（ステップ１５）。移行を確認できない場合はステップ１２で予測した生理開始日を修正しない。移行が確認できた場合は、次回生理開始日＝高温期の初日前日＋高温期平均日数とステップ１２で予測した生理開始日を修正し（ステップ１５）、合わせて将来のｎ周期先の生理開始日も次回生理開始日＋（ｎ−１）×有効周期日数平均と修正予測する（ステップ１６）。
【００２７】
なお、本実施形態では、高温期平均日数の算出を将来の生理開始日が予測できた時のみ行ったが、生理開始日入力手段で生理開始日が入力された時点で常に算出するようにしても良い。また、本実施形態では、高温期平均日数を算出する際には有効生理周期のみ対象としたが、高温期日数は周期日数の長さにかかわらずほぼ一定であるから、無効にした生理周期の内、周期日数の長さは平均より所定値以上であるが高温期平均体温と低温期平均体温の差は所定値以上あるもののみ高温期平均日数算出の対象としても良い。
【００２８】
以上のように本実施形態によれば、現生理周期における低温期の変動影響を除外してかつ個人差に応じた将来の生理開始日の予測精度を向上した婦人体温計を提供することができる。
【００２９】
（実施の形態４）
続いて本発明の第４の実施形態について説明する。図５は本実施形態の婦人体温計の構成を示すブロック図である。
【００３０】
６は、記憶手段４に記憶している基礎体温と生理開始日から生理開始日とその前日との体温差を算出する体温差算出手段である。第１の実施形態と同一機能を持つものは同一ステップ記号を用いている。生理開始日予測手段５と体温差算出手段６はマイクロコンピュータによって構成している。
【００３１】
以下本実施形態の生理開始日予測手段５及び体温差算出手段６の動作について図６のフローチャートにより説明する。まず、生理開始日予測手段５は、生理開始日入力手段３に生理開始日が入力された時点で、第３の実施形態同様、生理開始日を予測する又は、予測後修正する（ステップ１２〜ステップ１７）。但し、ステップ１３で生理開始日が予測できた場合は生理開始日予測手段５が高温期平均日数を算出すると同時に体温差算出手段６は有効周期について各々生理開始日前日基礎体温−生理開始日基礎体温を求めてその平均をとり平均体温差を算出し共に記憶手段４に記憶しておく（ステップ１８）。例えば−０．２℃等である。生理開始日予測手段５で予測した次回生理開始日を越えても生理が開始しない（生理開始日入力手段３に生理開始日入力がない）場合（ステップ１９）は、前日基礎体温−体温測定手段２で測定した基礎体温≧平均体温差の時にその日を次回生理開始日と修正予測する（ステップ２０〜ステップ２１）。合わせて将来のｎ周期先の生理開始日も次回生理開始日＋（ｎ−１）×有効周期日数平均と修正予測する（ステップ２２）。
【００３２】
なお、本実施形態では、体温差を求める対象を有効生理周期としたが、記憶手段に記憶した全生理周期を対象に行って統計的処理を施したものを用いてもかまわない。
【００３３】
以上のように本実施形態によれば、予測した次回生理開始日を越えても前記生理開始日入力手段で生理開始日入力がなかった場合即ち周期日数の長い生理周期でも個人差に応じて将来の生理開始日の予測精度を向上した婦人体温計を提供することができる。
【００３４】
（実施の形態５）
続いて本発明の第５の実施形態について説明する。図７は本実施形態の婦人体温計の構成を示すブロック図である。
【００３５】
７は、生理開始日予測手段５が予測した生理開始日を報知するための報知手段である。その他第４の実施形態と同一機能を持つものは同一ステップ記号を用いている。報知手段７は、ブザー音吹鳴部と液晶表示部で構成している。
【００３６】
以下、本実施形態の動作について図７及び図６のフローチャートにより説明する。生理開始日予測手段５が生理開始日の予測や修正予測を行う動作については第４の実施形態と同様である。生理開始日入力があると将来の生理開始日の予測が行われる。ステップ１８に進んだ時点で即ち、生理開始日の入力により将来の生理開始日が予測できた時点で、報知手段７で報知する。具体的にはブザー音吹鳴部で「ピピッ」と鳴らし、液晶表示部で次回以降の生理開始日を文字表示する。また、生理開始日入力手段３を用いて生理開始日の変更があった場合も、変更された生理開始日について新たに将来の生理開始日を予測し、報知する。さらに、低温期から高温期への以降が確認されて予測が修正された時（ステップ１７）及び予測した生理開始日を越えても生理開始日の入力がなく高温期中に前日の基礎体温と当日の基礎体温との差が体温差平均以上あって予測が修正された時(ステップ２２）には、やはり報知手段７で将来の生理開始日を報知する。
【００３７】
なお、本実施形態では、報知手段での報知をブザー音と液晶表示部での文字表示としたが、音声で報知しても良いし、表示しているカレンダーやグラフにマーク表示してもかまわない。また、生理開始日入力があった時、予測時、修正予測した時点以外に、使用者が好きな時に確認できるようにしても良いし、常時文字等で表示していてもかまわない。本実施形態では、このような使用者の確認時や常時表示だけでなく、新たに生理開始日を予測する時に使用者が気づくように意図的に報知するものである。
【００３８】
以上のように本実施形態によれば、使用者が常に予測精度の良い将来の生理開始日を認識できる婦人体温計を提供することができる。
【００３９】
（実施の形態６）
続いて本発明の第６の実施形態について説明する。図８は本実施形態の婦人体温計の構成を示すブロック図である。
【００４０】
８は、前記生理開始日予測手段が将来の生理開始日を予測するために用いるデータを現在の日から最新の１年以内の所定期間内のものだけに限定する記憶手段限定手段である。
【００４１】
以下、本実施形態の動作について図８により説明する。生理開始日入力手段３に生理開始日が入力されると、生理開始日予測手段５は、記憶手段４に記憶している生理開始日や基礎体温を用いて生理開始日の予測を行うが、その際記憶手段４に記憶されている生理開始日や基礎体温の内、記憶手段限定手段８によって現在の日から最新の１年以内の所定期間内のものだけに限定される。即ち、生理開始日予測手段５は、記憶手段限定手段８によって限定されたデータを用いて予測を行うものである。予測の動作は第１の実施形態と同様である。
【００４２】
なお、本実施形態では、記憶手段限定手段を記憶手段に記憶している内の一部に限定するものとしたが、記憶手段の容量を１年分しか記憶しないものとしても良い。
【００４３】
以上のように本実施形態によれば、女性の生理状態も成長あるいは加齢によって刻々と変化するものであるから、最近の生理周期変動に対応して将来の生理開始日の予測精度を向上した婦人体温計できる婦人体温計を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a female thermometer having a function of grasping a physiological state of a woman.
[0002]
[Prior art]
Conventionally, a period obtained by adding the average number of days of the menstrual cycle to the latest menstrual start date as the period of the menstrual cycle corresponding to each menstrual cycle as the interval of the menstrual start date input to the menstrual start date input means There was a female thermometer to predict and inform. Also, at the time when the transition from the low temperature period to the high temperature period was confirmed (when the basal body temperature determined to be the high temperature period was 3 consecutive days), that day was added 12 days (14 days counting from the first day of the high temperature period) There has been a female thermometer that predicts and reports that this is the next menstruation start date (Japanese Patent Laid-Open No. 62-183807).
[0003]
[Problems to be solved by the invention]
For women, knowing in advance the date of the future menstrual period is important for making preparations and planning future actions.
[0004]
However, the physiological state of women is very delicate, and even those who have a fairly stable period of menstrual cycle may easily disturb the period of menstrual cycle due to stress, etc. and become shorter or longer than the normal period of menstrual cycle. Occur. In particular, in modern times, women are increasingly exposed to stress, and the period of menstrual cycle is often disturbed.
[0005]
In the first thermometer, which simply takes an average with respect to such disturbance of the periodic days, even if the periodic days are stable, the average periodic days are disturbed by some disturbed periodic days. The prediction accuracy of the next menstruation start date has fallen.
[0006]
In addition, when the number of days in the cycle is disturbed, the number of days in the low temperature period only fluctuates, and the number of days in the high temperature period is said to be a substantially constant number of days. Therefore, the second thermometer has the same temperature as the first thermometer. Although it is not affected by the disturbed periodic days, it cannot cope with individual differences because the number of days in the high temperature period is fixed at 14 days. The high temperature period of 14 days is a standard, but in reality, it is about 12 to 16 days centering on the 14th, and it is a little longer or shorter for young people whose physiological functions are not stable and women per menopause. Since it is not possible to deal with such individual differences, the prediction accuracy is still lowered.
[0007]
The present invention solves the problems of such a conventional female thermometer, and an object of the present invention is to realize a female thermometer with improved prediction accuracy of a future physiological start date.
[0008]
[Means for Solving the Problems]
The first means of the present invention for achieving the object includes a body temperature measuring means for measuring a basal body temperature, a physiological start date input means for inputting the first day of each physiological cycle, and the body temperature measuring unit. A storage means for storing the measured basal body temperature and a physiological start date input by the physiological start date input means, and a future physiological period based on data stored in the storage means with a calendar function Menstrual start date predicting means for predicting the start date, and the physiological start date predicting means uses the interval of the physiological start date stored in the storage means as the number of physiological cycle days corresponding to each physiological cycle. With respect to the remaining effective physiological cycles, excluding the physiological cycle in which the difference between the average of the cycle days is more than the predetermined number of days and the difference between the high temperature average body temperature and the low temperature average body temperature within each menstrual cycle is less than the predetermined value To calculate the average period of effective menstrual cycle, It is configured to predict the physiological start date of the next n cycles ahead as (latest physiological start date + n × effective physiological cycle days average), and the abnormal physiological cycle is excluded to improve the prediction accuracy of the future physiological start date It is a female thermometer.
[0009]
Further, the second means of the present invention is configured such that the menstruation start date predicting unit predicts a future menstrual start date when the number of effective menstrual cycles is equal to or greater than a predetermined ratio of the number of all menstrual cycles. In addition, the thermometer has improved the accuracy of predicting the future menstrual start date.
[0010]
According to a third means of the present invention, the physiological start date predicting means can determine the transition from the low temperature period to the high temperature period based on the basal body temperature measured by the body temperature measuring means, on the day before the first day of the high temperature period. It is configured to predict and correct the start date of the next menstrual period by adding the average number of days in the high temperature period calculated from the basal body temperature of each menstrual cycle stored in the storage means. This is a female thermometer that excludes and improves the prediction accuracy of future menstrual start dates according to individual differences.
[0011]
The fourth means of the present invention comprises body temperature difference calculating means for calculating an average of the body temperature difference between the physiology start date and the previous day from the basal body temperature and the physiological start date stored in the storage means, and the physiological start date The predicting means determines that the basal body temperature measured by the body temperature measuring means is different from the basal body temperature of the previous day when the physiological start date is not input by the physiological start date input means even if the predicted next physiological start date is exceeded. When there is a difference in body temperature calculated by the calculation means, the day is corrected and predicted as the next physiological start date, and even if the predicted next physiological start date is exceeded, the physiological start date is input by the physiological start date input means. In the case where there is no period, that is, a menstrual thermometer with improved accuracy of predicting a future menstrual start date according to individual differences even in a menstrual cycle having a long cycle number.
[0012]
According to a fifth aspect of the present invention, there is provided a notifying means, and the notifying means is provided every time a physiological start date is input to the physiological start date input means or whenever the physiological start date predicting means makes a correction prediction. A feminine thermometer is configured to notify the future menstrual start date so that the user can always recognize the future menstrual start date with high prediction accuracy.
[0013]
The sixth means of the present invention comprises a storage means limiting means, and the data used by the physiological start date predicting means to predict a future physiological start date is the latest one from the current date by the storage means limiting means. The data thermometer is configured so as to be limited to data within a predetermined period within a year, and the prediction accuracy of the future menstrual start date is improved in response to recent physiological cycle fluctuations.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
(Embodiment 1)
A first embodiment of the present invention will be described below. FIG. 1 is a block diagram showing a configuration of a female thermometer of the present embodiment.
[0015]
A main body 1 (hereinafter simply referred to as a main body 1) of a female thermometer includes a body temperature measuring means 2, a physiological start date input means 3, a storage means 4, and a physiological start date predicting means 5.
The body temperature measuring means 2 is composed of a thermistor, the physiological start date input means 3 is composed of a push button switch, the physiological start date predicting means 5 is composed of a microcomputer, and the physiological start date predicting means 5 has a calendar function. is doing.
[0016]
The user measures the basal body temperature at rest by putting the body temperature measuring means 2 under the tongue while staying in the futon when getting up once every morning. Further, at the time of menstruation, the first day is inputted by the menstruation start date input means 3 as the menstruation start date. The basal body temperature thus measured and the inputted physiological start date are stored in the storage means 4 so that the date and time can be understood. The menstruation start date predicting unit 5 predicts future menstruation start dates from the next time on the basis of the data stored in the storage unit 4.
[0017]
The operation of the menstrual start date predicting means 5 of this embodiment will be described below with reference to the flowchart of FIG.
[0018]
The menstrual start date predicting means 5 first calculates the number of physiological period days for each physiological period from the interval of the physiological start date stored in the storage means 4. For example, if the oldest menstrual start date is January 1, 1998 and the second oldest menstrual start date is January 29, 1998, the cycle number of the first menstrual cycle is 28 days. Thereafter, the physiological cycle days are calculated for all the physiological cycles stored in the storage means 4 (step 1), and the average physiological cycle days is calculated (step 2). Next, for all the physiological cycles stored in the storage means 4, the difference between each physiological cycle day and the calculated physiological cycle day average is obtained, and if the difference is 4 days or more, the physiological cycle days of the physiological cycle are invalid. If the difference is 3 days or less, the difference between the high-temperature body temperature average and the low-temperature body temperature average of the physiological cycle is further checked. That is, when the difference is less than 0.3 ° C., the physiological cycle days of the physiological cycle are invalidated, and when the difference is 0.3 ° C. or more, the physiological cycle days are validated to determine an effective physiological cycle (step 3). To Step 6). The average of the physiological cycle days is calculated for the determined effective physiological cycle (step 7).

Is predicted (step 12). Only when this prediction is possible, the menstrual start date prediction means 5 performs the following operation (step 13). That is, first, the average number of days in the high temperature period is obtained for the effective physiological cycle (step 14). Next, it is checked whether the basal body temperature measured by the body temperature measuring means 2 has shifted from the low temperature period to the high temperature period (step 15). If the transition cannot be confirmed, the physiological start date predicted in step 12 is not corrected. If the transition is confirmed, the next menstruation start date = the day before the first day of the high temperature period + the average number of days in the high temperature period and the menstruation start date predicted in step 12 are corrected (step 15), and the menstruation start in the future n cycles ahead The date is also corrected and predicted as the next period start date + (n−1) × effective cycle days average (step 16).

However, if the physiological start date can be predicted in step 13, the physiological start date predicting means 5 calculates the average number of days in the high temperature period, and the body temperature difference calculating means 6 simultaneously calculates the basic body temperature on the day before the physiological start date-the physiological start date basis for the effective period. The body temperature is obtained and averaged, and an average body temperature difference is calculated and stored in the storage means 4 (step 18). For example, it is -0.2 degreeC. If the menstruation does not start even if the next menstrual start date predicted by the menstrual start date predicting means 5 is exceeded (the physiological start date input means 3 has no physiological start date input) (step 19), the previous day basal body temperature-body temperature measuring means When the basal body temperature measured in 2 is equal to or greater than the average body temperature difference, the day is corrected and predicted to be the next period start date (step 20 to step 21). In addition, the physiological start date of the future n cycles ahead is also corrected and predicted as the next physiological start date + (n−1) × average effective cycle days (step 22).

Specifically, the buzzer sound blowing section sounds “beep”, and the next menstruation start date is displayed in characters on the liquid crystal display section. Also, when there is a change in the menstrual start date using the menstrual start date input means 3, a new menstrual start date is predicted and notified of the changed menstrual start date. Further, when the prediction from the low temperature period to the high temperature period is confirmed and the prediction is corrected (step 17), and even if the predicted physiological start date is exceeded, there is no input of the physiological start date and the basal body temperature and the day of the previous day during the high temperature period. When the prediction is corrected because the difference from the basal body temperature is equal to or higher than the average body temperature difference (step 22), the notification unit 7 also notifies the future physiological start date.
