Description of the invention: [Technical field to which the invention pertains] The present invention relates to a predictive electronic thermometer. [Prior Art] Electronic thermometers can be roughly classified into two types. The first one is the so-called "measured". It is an electronic thermometer that directly displays the temperature of the temperature measuring element located in the temperature measuring unit. In such a thermometer, the temperature measuring unit is placed on a subject to be measured, such as under the armpit or in the mouth, and is regarded as a body temperature at a temperature (balanced temperature) at which the temperature does not rise again. If you want to measure the equilibrium temperature with a measured thermometer, it usually takes 5 minutes in the mouth and 10 minutes in the armpit. In the actual measurement type, there is also a case where the buzzer sounds when the temperature rises below a certain level, as a message that the body temperature measurement ends. In this case, although the measurement can be completed in 3 to 5 minutes, the measured body temperature will become slightly lower than the actual balance. Others have an electronic thermometer called "predictive". The predictive electronic thermometer measures the relationship between the characteristic of the temperature rise curve and the equilibrium temperature by statistical methods or by heat conduction to calculate the correction amount, and then adds the correction amount to the temperature 値 to predict and display the equilibrium body temperature (see Japanese Patent Literature 1 to 4). In these predictive electronic thermometers, the predicted results are displayed in about 1 to 2 minutes from the start of the measurement. The conventional predictive electronic thermometer is a method of predicting the equilibrium temperature by performing a curve approximation or the like based on a temperature and a temperature gradient at a certain time, or assuming a heat conduction method in consideration of heating a small object. In this case, it is equal to the initial enthalpy of the curve of the temperature rise of 1,253,922, and only the part after a certain period of time is considered, that is, the part of the temperature conduction from the inside to the surface of the living body. It’s awkward. In other words, since the initial portion of the temperature rise curve is susceptible to the initial state of the temperature measuring portion or the skin surface, and the states are subject to change, the initial portion of the temperature rise curve is excluded by § 10. [Patent Document 1] Japanese Patent Laid-Open No. 5-2 - 75, No. 3, 85 [Patent Document 2] Japanese Patent Laid-Open No. Hei-5-5-78,220 (Patent Document 3) Japanese Patent Application Japanese Patent Publication No. 5-9 -1 87, No. 3 (Patent Document 4) Japanese Patent Application Laid-Open No. Hei No. 7 - 1 1 1, 3 8 3 SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION However, as above In the method of the conventional predictive electronic thermometer, since the influence of the initial stage is not considered as described above, generally, the shorter the measurement time, the worse the prediction accuracy becomes. Therefore, if you want to make predictions with good accuracy, you must wait until the initial impact is eliminated, so that the time until the initial impact is eliminated is required. For example, a thermometer of this type requires a prediction time of 60 seconds to 120 seconds. The present invention has been accomplished to solve the problems of the prior art, and the object thereof is to provide a short time and high accuracy. Electronic thermometer for temperature measurement. In order to achieve the above object, the present invention relates to an electronic thermometer which is provided with a temperature measuring device for measuring body temperature, and measured from a temperature of 1,253,922 until a certain time has elapsed. The temperature change information and the second temperature change information measured thereafter are used to predict the equilibrium body temperature. According to the above configuration, since the equilibrium temperature can be predicted from the initial temperature change information of the start of measurement, the temperature can be measured in a short time and with high accuracy. The first temperature change information is preferably information measured from the start of measurement until about 20 seconds have elapsed. The first temperature change information is preferably a physical quantity other than the temperature. Preferably, the first temperature change information is a duration indicating a temperature rise, and the second temperature change information is a temperature gradient. The first temperature change information indicating the duration of the temperature rise is the time from the peak to the specific enthalpy. Preferably, the two temperature detecting devices are disposed at positions different in thermal characteristics, and the first temperature change information is obtained by the difference between the temperatures detected by the two temperature detecting devices, and the second temperature change information is determined by any temperature. Detecting the temperature gradient measured by the device. Preferably, the first temperature change information measured by the two temperature detecting means is calculated by a linear relationship between a temperature detected by one of the temperature detecting means and a temperature detected by the two temperature detecting means. After that. EFFECTS OF THE INVENTION According to the present invention, it is possible to provide a thermometer which can measure temperature in a short time and with high accuracy. [Embodiment] Xia_1 embodiment -7- 1253922 A predictive electronic thermometer according to an embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a block diagram showing the basic structure of a predictive electronic thermometer. The predictive electronic thermometer 1 is mainly composed of a temperature measuring unit 2, a predictive computing unit 3 for predicting the calculated balanced body temperature, a display unit 4 for displaying the predicted result, and a power supply for supplying power to the predictive computing unit 3 and the display unit 4. 5. A power switch 6 for switching the power on and off. The temperature measuring unit 2 has a temperature sensor such as a thermistor. The prediction computing unit 3 is configured to monitor the signal from the temperature measuring unit 2 and predict the calculated equilibrium body temperature based on the temperature or the elapsed time information. The result calculated by the prediction calculation unit 3 is sent to the display unit 4' to display the predicted body temperature on the display unit 4. Fig. 2 is a schematic view showing the structure of a predictive electronic thermometer 1 〇, 1 1 . The predictive electronic thermometers 10 and 11 are a rod-shaped probe 8 having a substantially rectangular parallelepiped main body portion 7 and extending in the longitudinal direction from the longitudinal direction of the main body portion 7. The temperature measuring unit 2 is disposed at the front end of the probe 8. The temperature sensor 2 1 is disposed on the inner surface of the temperature measuring unit 2 that is formed to be hollow. The heat is transmitted from the outer surface of the temperature measuring unit 2 to the temperature sensor (temperature detecting device) 2 1 (Fig. 2 ( a ) ). The temperature sensor 21 is electrically connected to the prediction calculation unit 3 disposed inside the main body unit 7 to input the output of the temperature sensor 21 to the prediction calculation unit 3, and the configuration of the temperature measurement unit 2 is not limited to the above. The structure described above may be configured as two temperature sensors having the first temperature sensor 211 and the second temperature sensor 212. Here, the first temperature sensor 2 1 1 (temperature detecting device) and the second temperature sensor (temperature detecting device) 2 1 2 ' respectively have different thermal characteristics (thermal conductivity, specific heat, and density) through 1253922. The material (heat insulating material 221, 222 ) of any one of the eight or the like (the combination of the three) is disposed on the inner surface of the temperature measuring portion 2 formed as a hollow (the arrangement of the heat insulating material is such that Since the thermal characteristics of the i-temperature sensor 2 n and the second temperature sensor 2 1 2 are different from each other, it is also possible to adopt a method in which only one insulating material is provided. Therefore, the heat can be transmitted from the outside of the temperature measuring unit 2 to the first temperature sensor 2 1 1 via the heat insulating material 2 2 1 , and the same heat can be conducted to the second temperature sensor 212 via the heat insulating material 222. The first temperature sensor 2 1 1 and the second temperature sensor 2 12 are electrically connected to the prediction computing unit 3 disposed inside the main body unit 7, and the first temperature sensor 2 1 1 and the second temperature sensor 2 1 The output of 2 is input to the prediction calculation unit 3, and the time change of the temperature rise of the thermosensitive electron progenitor after the measurement is started from the squat or the mouth is generally shown as a graph in Fig. 3 . For the ascending curve, if the temperature rise is applied when heating a small object: [1] T(t) = Ts - (Ts - TO) exp (- at) ^ where T(t): at time t Temperature, Ts: temperature of the heating body (green body temperature), TO: initial temperature of the object, a: constant, it is known that the temperature rise curve can be divided into two parts around the time of about 20 seconds (third The dotted line in the figure). The portion of the thermistor temperature rise curve from the start of measurement to about 20 seconds reflects the surface temperature of the autologous body, the initial temperature of the probe, and the heat transfer method of the living body to the probe. -9- 1253922 In the temperature rise curve of the thermistor, from the start of the measurement to about 20 seconds after the measurement, the condition of the heat-producing body is transmitted to the surface due to the reaction of the living body, and Individual measurement objects, and therefore their temperature changes are different. In the past prediction method, the temperature data of a portion of the temperature rise curve from about 20 seconds after the start of the measurement is used. The initial surface temperature of the living body reflects the relationship between the deep body temperature and the external environment. The method of conduction of heat to the probe changes depending on the state of the object to be measured, the surface of the object to be measured and the surface of the probe, and the state of contact between the object to be measured and the probe. In other words, even if the same person is measured, since the state of the measurement is changed for each measurement, it has been conventionally used in such a manner that the temperature information of the portion which is not easily changed is used, and the temperature rises after sufficient time has elapsed. The change in the curve compares the temperature information of the stable part. However, if the opposite is true, and the information about the deep body temperature and the external environment, the conduction method of the heat to the probe, the surface state, and the contact state of the initial temperature rise portion are reversed, it is expected to be improved. Accuracy of measurement in a short time. As described above, information on temperature changes in the initial stage from the start of measurement until a certain period of time elapses (for example, a period of about 2 seconds from the start of measurement) indicates deep body temperature and external environment, and heat to the probe. The conduction method, the surface state, the contact state, and the information reflected are equivalent to the first temperature change information. On the other hand, it is information on the temperature change in the initial stage from the start of measurement until a certain period of time elapses (for example, after about 20 seconds from the start of measurement), indicating that the heat of reaction of the living body is from the inside of the living body. The state of surface conduction, and the information reflected, is equivalent to the second temperature change information. However, 1253922 is that the specific time is not limited to about 20 seconds, which varies depending on various factors. An example of a parameter indicating an initial temperature rise state is a time when a mode of using a sensor is used to reach a certain 値 (for example, 0 · 2 ) by the maximum 値 of the gradient of the temperature rise curve (Δ T(t)). (Expressed in r (seconds) in Figure 4). It is a parameter indicating the continuation of the temperature rise of the initial part. An example of a specific equilibrium temperature prediction method using the same is shown in Fig. 5. First, the clock is started simultaneously with the start of the measurement (step 1), and the temperature T(t) is obtained from the output of the temperature sensor 21 (step 2). Next, it is judged whether or not the temperature T(1) is 31 ° C or higher, or T (t) - T (t - 0.5) is 0.2 ° C or higher (step 3). If the condition of at least one of the conditions is met, the clock is reset (step 4). On the other hand, if none of the conditions is met in step 3, the process returns to step 2. After the clock is reset in step 4, the temperature T(t) is obtained from the output of the temperature sensor 2 1 (step 5). Further, the temperature gradient is calculated from the difference between the temperature at that time and the data of the time before 2 seconds: Δ T(t) = τ(1) - T(t - 2.0) (step 6). Then, it is judged whether or not the temperature gradient Δ T(t) at the time is less than the temperature gradient Δ T ( t − 〇 · i ) before 0.1 second (step 7). In step 7', if the temperature gradient at that time is equal to or greater than the temperature gradient before 〇.丨, then return to step 5. In step 7, if the temperature gradient at this time is less than the temperature gradient before 0 · 1 second, the clock 该t at that time is substituted in tm (step 8). 1253922 Next, determine the temperature gradient: Δ T(t) = T(t) - T(t-2.0) is less than 0.2 °C (step 9). In step 9, if the temperature T(t) is equal to or greater than 0.2t: then return to step 8. In step 9, if the temperature gradient Δ T(t) is less than 0.2 ° C, the clock 该t at that time is substituted in tn (step 10). Next, τ = tn - tm is calculated from tm and tn (step 1 1 ). The r calculated by this is the time required for the temperature gradient to change from a peak 小于 to less than 0.2 °C. Next, from this point of time, the temperature gradient Δ 5 T(t) = T(t) - T(t-5) is calculated from the difference between the data 5 seconds before the time (step 12). Use these 値 as shown below [number 2] or [number 3] [number 2]

For example, continuously calculate Tb(t) 値 and determine whether the change is less than the preset 値(〇. it:), or whether it has passed t = 30 seconds, etc. (step 14), if none of them meets In any of these conditions, return to step 〖2. When any of these conditions is satisfied, Tb(t) 将该 at that time is displayed as a prediction 値 on the display unit 4 (step 15). Here, A, B, C, and D (E, F, G) are pre-extracted with many data, and the constants determined by statistical methods. The equation [number 4] shown below is taken as an example of the conventional prediction method 1253922 and compared with the prediction accuracy of the equation (1) according to an example of the present invention [number 4]

Tb(t)= A T(t) + Β Δ 5 T(t) + C ( 3 ) 將時間區分成每1 0秒鐘，並按各時間分別計算得最適當 的a B C D (爲式（1 )之情形）、A B C (爲式（3 )之情形 )’然後使用該等値來預測77人之體溫的結果就是第6圖 〇 其在3 0秒鐘時之各係數則爲： 在式（1)爲 A = 0.725、B = 5.536、C = - 0.0732、D = 10.857 ； 在式（3)爲 A = 0.705、B = 4.815、C = 11.123。 如第6圖所示，使用本發明之式（1 )時，則在自開始測 定起3 0秒鐘之時刻，即能獲得與其以後再經過時間的時刻 相等之精確度。與此相對，在使用式（3 )的以往之方法時 ，則直至獲得相等精確度卻自開始測定起已經過5 0秒鐘以 上。如此，若根據本發明，則與以往之預測式電子體溫計 相比較，可在短時間實現高準確度之體溫測定。 在具有如第2(b)圖所示2個溫度感知器的電子體溫計 之情形下，表示初期溫度上升狀態之參數，也可使用在同 一時刻的第1溫度感知器2 1 1與第2溫度感知器2 1 2之溫 度差：△ 12 T(t) = Tl(t)- T2(t)爲由最大値變爲某一定値（ 例如0 · 5 )之時間（在第7圖中，以r (秒鐘）表示。）。 此情形下之平衡溫度預測方法，爲將第5圖所示△ T(t)以 1253922 △ T(t)取代者。如第7圖所示，△ T(t)係因自開始測定 起經過約3 0秒鐘而將趨於非常安定，因此，將該値作爲參 數來使用，也可在短時間獲得高度精確的預測。 除上述以外，表示初期溫度的上升之參數，也可採用微 分之最大値或微分會變得最大値所需之時間等。 第2實施例形熊 如第2圖所示，在使用2個溫度感知器的電子體溫計1 1 之情形下，則可使用其他參數來預測平衡體溫。關於電子 體溫計11，則已於第1實施例形態中加以說明，因此就預 測方法說明如下。 在具有2個溫度感知器之電子體溫計1 1，則利用第1溫 度感知器211與第2溫度感知器212之溫度差與其時之溫 度係具有線性關係來獲得初期特性値。換言之，第丨溫度 感知器21 1之溫度値Tl(t)與第2溫度感知器212之溫度値 T2(t)之差△ 12T(t)與其時刻的溫度Tl(t)，係經過某一時間 時’則將成1付合· 〔數5〕Tb(t)= AT(t) + Β Δ 5 T(t) + C ( 3 ) The time is divided into every 10 seconds, and the most appropriate a BCD is calculated for each time (for equation (1) The case), ABC (for the case of equation (3))' then use the enthalpy to predict the body temperature of 77 people is the result of Figure 6 and its coefficients at 30 seconds are: ) is A = 0.725, B = 5.536, C = - 0.0732, D = 10.857; in equation (3), A = 0.705, B = 4.815, C = 11.123. As shown in Fig. 6, when the formula (1) of the present invention is used, the accuracy equal to the time after the elapse of time can be obtained at the time of 30 seconds from the start of the measurement. On the other hand, when the conventional method of the formula (3) is used, it is more than 50 seconds since the start of the measurement until the equal accuracy is obtained. As described above, according to the present invention, it is possible to achieve high-accuracy body temperature measurement in a short period of time as compared with the conventional predictive electronic thermometer. In the case of an electronic thermometer having two temperature sensors as shown in Fig. 2(b), the first temperature sensor 2 1 1 and the second temperature at the same time may be used as parameters indicating the initial temperature rise state. Temperature difference of the sensor 2 1 2: Δ 12 T(t) = Tl(t) - T2(t) is the time from the maximum 値 to a certain 値 (for example, 0 · 5) (in the seventh figure, r (seconds) means .). The equilibrium temperature prediction method in this case is to replace Δ T(t) shown in Fig. 5 with 1253922 Δ T(t). As shown in Fig. 7, ΔT(t) tends to be very stable after about 30 seconds from the start of measurement. Therefore, using 値 as a parameter can also be highly accurate in a short time. prediction. In addition to the above, the parameter indicating the rise of the initial temperature may be the time required for the maximum 値 or differential of the differential to become maximum. Second Embodiment Shape Bear As shown in Fig. 2, in the case of an electronic thermometer 1 1 using two temperature sensors, other parameters can be used to predict the equilibrium body temperature. The electronic thermometer 11 has been described in the first embodiment, and therefore the prediction method will be described below. In the electronic thermometer 1 having two temperature sensors, the temperature difference between the first temperature sensor 211 and the second temperature sensor 212 is linearly related to the temperature at that time to obtain the initial characteristic 値. In other words, the difference Δ 12T(t) between the temperature 値Tl(t) of the second temperature sensor 21 1 and the temperature 値T2(t) of the second temperature sensor 212 and the temperature Tl(t) at the time thereof are passed through a certain At the time of time, it will be 1 in one. [5]

Tl(t)= ΗΔ 12 T(t) + m 之直線關係（第8圖）。將此時之Η或m用作爲特性値。 在第9圖係表示具有2個溫度感知器的電子體溫計1 1之 具體的平衡溫度預測方法。在此則就利用m之情形加以說 明。 首先與開始測定同時起動時鐘（步驟2 1 )，並取得第1 溫度感知器2 1 1及第2溫度感知器2 1 2之時系列溫度資料 1253922 ’由任一者之輸出取得溫度T(t)(步驟22 )。 其次，判定溫度T(t)是否符合爲31 °C以上，或是否符合 T(t) - T(t-0.5)爲0.2t以上中之任一條件（步驟23)。若 爲符合該等條件中至少任一者之條件時，則將時鐘予以復 位（步驟24 )。另一方面，在步驟23，均未符合該條件中 任一者時，則返回步驟22。 在步驟23則使時鐘復位後，由第1溫度感知器之輸出取 得溫度Tl(t)、由第2溫度感知器的溫度之輸出取得溫度 T2(t)(步驟25 )。然後計算得該時刻的由第1溫度感知器 2 1 1所檢測之溫度T 1 (t)與由第2溫度感知器2 1 2所檢測之 溫度T2⑴之溫度差：△ 12T(t) = Tl(t)- T2(t)(步驟26)。 由數個Tl(t)、Δ12Τ⑴計算能符合：m = Tl(t)- ΗΔ12 T(t)之條件的m、Η (步驟27)。具體而言，例如以1秒鐘 間隔取得資料，經過t秒鐘時，則以： 〔數6〕 m = Tl(t)- ΗΔ 12 T(t) m = Tl(t-l)- ΗΔ 12 T(t-l) 之聯立方程式計算得m、H，並將此時之m與H作爲m(t) 之參數。按順序繼續進行如此之計算。 經由如上述所計算得之m(t)係如第10圖所示般約以1〇 秒鐘將成爲一定値。將該成爲一定時之値用作爲m。具體 而言，判斷其時刻之m(t)，與自其時刻起1秒鐘前的m(t-1)之差的絕對値是否比0.1小（步驟28 )。在步驟28 ’ m(t)與m(t-l)之差的絕對値爲0.1以上時，則回到步驟28 1253922 。另一方面在步驟2 8，m⑴與m (t - 1 )之差的絕對値若小於 〇.1時，則將其時刻之ni(t)作爲m (步驟29)。 其次，由該時刻，與自該時刻起5秒鐘前的資料之差來 決定溫度梯度：△ 12 T(t) = T(t) - T(t-5)。 使用該等以如下所示〔數7〕或〔數8〕計算得Tb。 〔數7〕Tl(t) = linear relationship of ΗΔ 12 T(t) + m (Fig. 8). Use Η or m at this time as the characteristic 値. Fig. 9 shows a specific equilibrium temperature prediction method of the electronic thermometer 1 1 having two temperature sensors. Here, the case of using m is explained. First, the clock is started at the same time as the start of the measurement (step 2 1 ), and the temperature information of the first temperature sensor 2 1 1 and the second temperature sensor 2 1 2 is obtained, and the temperature is obtained from the output of either one. ) (step 22). Next, it is judged whether or not the temperature T(t) satisfies 31 ° C or more, or whether T(t) - T(t - 0.5) is equal to any of 0.2 t or more (step 23). If the condition of at least one of the conditions is met, the clock is reset (step 24). On the other hand, if none of the conditions is met in step 23, the process returns to step 22. After the clock is reset in step 23, the temperature T1(t) is obtained from the output of the first temperature sensor, and the temperature T2(t) is obtained from the temperature of the second temperature sensor (step 25). Then, the temperature difference between the temperature T 1 (t) detected by the first temperature sensor 2 1 1 and the temperature T2 (1) detected by the second temperature sensor 2 1 2 is calculated: Δ 12T(t) = Tl (t) - T2(t) (step 26). m, Η (step 27) which can satisfy the condition of m = Tl(t) - Η Δ12 T(t) is calculated from a plurality of Tl(t), Δ12 Τ(1). Specifically, for example, data is acquired at intervals of one second, and after t seconds, it is: [number 6] m = Tl(t) - Η Δ 12 T(t) m = Tl(tl) - ΗΔ 12 T( The joint equation of tl) calculates m and H, and m and H at this time are taken as parameters of m(t). This calculation is continued in order. The m(t) calculated as described above is approximately constant for about 1 second as shown in Fig. 10. Use this as a m for a certain period of time. Specifically, it is judged whether or not the absolute 値 of the difference between the time m(t) and the m(t-1) one second before the time is smaller than 0.1 (step 28). When the absolute 値 of the difference between step 28' m(t) and m(t-1) is 0.1 or more, the process returns to step 28 1253922. On the other hand, if the absolute 差 of the difference between m(1) and m (t - 1 ) in step 2, 8 is less than 〇.1, ni(t) at the time is taken as m (step 29). Next, the temperature gradient is determined by the difference between the time and the data 5 seconds before the time: Δ 12 T(t) = T(t) - T(t-5). The Tb was calculated by using [the number 7] or [the number 8] as shown below. [Number 7]

Tb(t)= I T(t) + JA 12 T(t) + K m + L ( 4 ) 〔數8〕Tb(t)= I T(t) + JA 12 T(t) + K m + L ( 4 ) [Number 8]
