Description

本考案は、一般に、測温対象者の体温を測定する温度計に関し、特に測温部を耳孔に挿入して鼓膜の温度を測る耳式体温計に関するものである。   The present invention generally relates to a thermometer that measures the body temperature of a temperature measurement subject, and more particularly to an ear-type thermometer that measures the temperature of the eardrum by inserting a temperature measurement unit into the ear canal.

従来の耳式体温計の代表例について、説明の便宜上、図９および図１０を参照して説明する。図９は従来の耳式体温計の動作原理を示す概略構成図であり、図１０は従来の耳式体温計の測温部の縦断面図である。図９に示すように、従来の代表的耳式体温計のプローブ１０は、サーモパイル１１を用いている。一般に、サーモパイルは、冷接点と温接点との間の温度差により電位差を生じる（ゼーベック効果）。サーモパイルを温度測定用プローブとして用いるためには、熱電対と同様に室温（環境温度）補償が必要となる。そのために、従来の耳式体温計では、サーミスタ１２が用いられている。   A representative example of a conventional ear thermometer will be described with reference to FIGS. 9 and 10 for convenience of explanation. FIG. 9 is a schematic configuration diagram showing the operation principle of a conventional ear thermometer, and FIG. 10 is a longitudinal sectional view of a temperature measuring unit of the conventional ear thermometer. As shown in FIG. 9, a thermopile 11 is used in a probe 10 of a conventional representative ear thermometer. In general, a thermopile generates a potential difference due to a temperature difference between a cold junction and a hot junction (Seebeck effect). In order to use the thermopile as a temperature measurement probe, room temperature (environmental temperature) compensation is required as in the case of a thermocouple. Therefore, the thermistor 12 is used in the conventional ear-type thermometer.

測温対象者の体温がサーモパイル１１の冷接点温度と等しいとき、プローブ１０の出力はゼロ（ゼロ点）となる。一方、測温対象者の体温がサーモパイル１１の冷接点温度よりも高いとき、プローブ１０の出力は非線形的に大きくなる。   When the body temperature of the temperature measurement subject is equal to the cold junction temperature of the thermopile 11, the output of the probe 10 is zero (zero point). On the other hand, when the body temperature of the temperature measurement subject is higher than the cold junction temperature of the thermopile 11, the output of the probe 10 increases nonlinearly.

プローブ１０を用いて体温を測定する場合、プローブ１０の出力は微弱である。そのために、プローブ１０の出力を信号増幅器１３によって信号処理が可能なレベルまで増幅する。リニアライザ１４ａによって非線形出力を線形化する。一方、サーミスタ１２の出力も非線形であるため、リニアライザ１４ｂによって線形化する。   When the body temperature is measured using the probe 10, the output of the probe 10 is weak. For this purpose, the output of the probe 10 is amplified by the signal amplifier 13 to a level at which signal processing is possible. The nonlinear output is linearized by the linearizer 14a. On the other hand, since the output of the thermistor 12 is also non-linear, it is linearized by the linearizer 14b.

環境温度が安定した状態では、サーミスタ１２の温度とサーモパイル１１の冷接点温度とは等しい。プローブ１０からの出力を線形化した信号は、サーミスタ１２の温度と測温対象者の体温との差となる。したがって、プローブ１０の出力を線形化した信号を放射率補正器１５によって補正し、その補正信号とサーミスタ１２の出力を線形化した信号とを加算器１６で室温補償または冷接点温度補償した後、温度換算器１７で環境温度補正を行えば、測温対象者の体温が求められる。これを表示器１８に表示する。   In a state where the environmental temperature is stable, the temperature of the thermistor 12 and the cold junction temperature of the thermopile 11 are equal. The signal obtained by linearizing the output from the probe 10 is the difference between the temperature of the thermistor 12 and the body temperature of the temperature measurement subject. Therefore, after the signal obtained by linearizing the output of the probe 10 is corrected by the emissivity corrector 15, the correction signal and the signal obtained by linearizing the output of the thermistor 12 are compensated at room temperature or cold junction temperature by the adder 16. If the environmental temperature is corrected by the temperature converter 17, the body temperature of the temperature measurement subject is obtained. This is displayed on the display 18.

サーモパイルは、個体差の感度のバラツキが大きいため、一定の温度差であっても出力電圧にバラツキを生じる。そのために、サーモパイルを用いたプローブに対する感度調整（校正作業）が個々に必要となる。サーモパイルの赤外線吸収膜（赤外線吸収膜と温接点とが一体となった部分、図１０の１１６参照）は、測温対象者からの赤外線を吸収して温度が上昇するが、サーモパイルのパッケージからも赤外線吸収膜に対して赤外線は放射されている。通常の使用法では、パッケージはサーモパイルのヒートシンク（吸熱部）と同一の温度とみなせるが、外部からの要因により急激な温度変化が与えられると、パッケージの頭部とサーモパイルのヒートシンクとの間に温度差が生じ、プローブの出力は過渡的に不安定になる。   Since the thermopile has a large variation in sensitivity among individual differences, the output voltage varies even with a certain temperature difference. Therefore, sensitivity adjustment (calibration work) for the probe using the thermopile is individually required. The infrared absorption film of the thermopile (the portion where the infrared absorption film and the hot junction are integrated, see 116 in FIG. 10) absorbs infrared rays from the temperature measurement subject, and the temperature rises. Infrared rays are radiated to the infrared absorbing film. Under normal usage, the package can be regarded as the same temperature as the heat sink of the thermopile, but if there is a sudden temperature change due to external factors, the temperature between the head of the package and the heat sink of the thermopile A difference occurs and the probe output becomes transiently unstable.

そこで、図１０に示すように、プローブ１０に温度変化が均一で緩やかに加わるようにするために、サーモパイル１１０を熱伝導度がよい金属（例えば、アルミニウム）ホルダ１１１内に設置し、さらに断熱材として空気層１１２と樹脂１１３とで囲むようにカバー１１４を設けている。サーモパイル１１０の前面に金属管１１５を設け、測温対象者からの熱放射の影響を小さくする。金属管１１５は、放射率を小さくするように金メッキが施され、導波管の働きを持たされている。冷接点温度補償用のセンサとして半導体、サーミスタ等が用いられる。しかし、サーミスタは、生産コストが安く、精度がよいために広く用いられている。   Therefore, as shown in FIG. 10, in order to apply a uniform and gentle temperature change to the probe 10, a thermopile 110 is installed in a metal (for example, aluminum) holder 111 having a good thermal conductivity, and further a heat insulating material. A cover 114 is provided so as to be surrounded by the air layer 112 and the resin 113. A metal tube 115 is provided in front of the thermopile 110 to reduce the influence of thermal radiation from the temperature measurement subject. The metal tube 115 is gold-plated so as to reduce the emissivity, and has a waveguide function. A semiconductor, thermistor, or the like is used as a cold junction temperature compensation sensor. However, the thermistor is widely used because of its low production cost and high accuracy.

サーモパイル冷接点部とサーミスタとの熱結合が悪いと、温度差を生じ、正確な計測ができなくなる。サーミスタ（図示せず）をサーモパイル１１０と同一パッケージ内に取り付け、サーモパイル冷接点部ヒートシンクとサーミスタとの熱結合度を高める。同一規格のサーミスタでもＢ常数（抵抗温度特性で任意の２点の温度から求めた抵抗値変化の大きさを表す定数）にバラツキがあるため、広い環境温度範囲で精度を保つのは困難である。例えば、電子体温計のサーミスタで人体の測定温度範囲を３４−４２℃とすると、サーミスタ精度は８℃の範囲内で精度を保つだけでよい。しかし、サーモパイルの環境温度範囲を５−４０℃とした場合、サーミスタ精度は３５℃（４０−５＝３５）の範囲内で精度を保たなければならない。   If thermal coupling between the thermopile cold junction and the thermistor is poor, a temperature difference will occur and accurate measurement will not be possible. A thermistor (not shown) is mounted in the same package as the thermopile 110 to increase the thermal coupling between the thermopile cold junction heat sink and the thermistor. Even with thermistors of the same standard, the B constant (a constant representing the magnitude of the change in resistance value determined from the temperature at any two points in the resistance temperature characteristics) varies, so it is difficult to maintain accuracy over a wide environmental temperature range. . For example, if the thermistor of an electronic thermometer has a measurement temperature range of 34-42 ° C., the thermistor accuracy only needs to be maintained within the range of 8 ° C. However, when the ambient temperature range of the thermopile is 5-40 ° C., the thermistor accuracy must be maintained within the range of 35 ° C. (40−5 = 35).

図１０に示すプローブ１０の構造では、環境温度上昇中にサーモパイル１１０とプローブ１０の先端部間に温度差を生じ、測温部はサーモパイル１１０よりも温度が高くなるため、正方向の誤差を生じる。環境温度下降中では、サーモパイル１１０とセンサ先端部間に温度差を生じ、測温部はサーモパイル１１０よりも温度が低くなるため、負方向の誤差を生じる。この誤差を少なくするため、サーモパイル１１０をカバー１１４で囲み温度変化の影響を少なくしているが、金属ホルダ１１１の大型化は測温対象者との関係から限界がある。環境温度変化に対する誤差対策として、サーモパイル・パッケージ内のサーミスタの単位時間当たりの変化率を計算してプローブ出力を補正し、誤差を少なくしている。   In the structure of the probe 10 shown in FIG. 10, a temperature difference is generated between the thermopile 110 and the tip of the probe 10 while the environmental temperature is rising, and the temperature measuring unit has a temperature higher than that of the thermopile 110, so that an error in the positive direction occurs. . While the environmental temperature is decreasing, a temperature difference is generated between the thermopile 110 and the tip of the sensor, and the temperature measuring unit has a temperature lower than that of the thermopile 110, so that an error in the negative direction occurs. In order to reduce this error, the thermopile 110 is surrounded by the cover 114 to reduce the influence of temperature change. However, the increase in the size of the metal holder 111 is limited due to the relationship with the temperature measurement subject. As a countermeasure against errors in environmental temperature changes, the rate of change per unit time of the thermistor in the thermopile package is calculated to correct the probe output to reduce the error.

そこで、本出願人は、先の特許出願（特許文献１参照）において、短時間の環境温度変化による影響を排除し、環境温度変化による誤差を生じない耳式体温計を提案した。   Therefore, in the previous patent application (see Patent Document 1), the present applicant has proposed an ear-type thermometer that eliminates the effect of a short-term change in environmental temperature and does not cause an error due to a change in environmental temperature.

前記特許文献１に係る耳式体温計は、樹脂製の第１断熱部材と、第１断熱部材の先端に接続された樹脂製の第２高断熱部材と、第１断熱部材および第２高断熱部材を覆う保護カバーと、第１断熱部材および第２高断熱部材内に埋め込まれたサーミスタリード細線と、ならびにサーミスタリード細線の先端折返し部分のほぼ中央に装着された超高速応答サーミスタとを含むプローブを備えている。   The ear-type thermometer according to Patent Document 1 includes a resin-made first heat insulating member, a resin-made second high heat insulating member connected to the tip of the first heat insulating member, a first heat insulating member, and a second high heat insulating member. A probe that includes a protective cover that covers the wire, a thermistor lead thin wire embedded in the first heat insulating member and the second high heat insulating member, and an ultrafast response thermistor mounted approximately at the center of the tip folding portion of the thermistor lead thin wire. I have.

前記特許文献１に係る発明によれば、サーミスタが精度を保つ温度範囲は、測温対象者の体温範囲のみでよく、従来のサーモパイルを用いた耳式体温計のように、測定環境温度範囲全域においてサーミスタの測定精度を保つ必要がない。その結果、この特許出願に係る発明のプローブは環境温度の変化（短時間の温度変化）の影響を受けない。   According to the invention according to Patent Document 1, the temperature range in which the thermistor maintains accuracy is only the body temperature range of the temperature measurement subject, and in the entire measurement environment temperature range, such as an ear thermometer using a conventional thermopile. There is no need to maintain thermistor measurement accuracy. As a result, the probe of the invention according to this patent application is not affected by changes in environmental temperature (short-term temperature changes).

しかしながら、前記特許文献１に係る耳式体温計は、小型化が難しいこと、消費電力が大きいこと、回路が複雑であること、一部に高価な部品を必要とするために全体のコストが高くなることなどの問題がある。   However, the ear thermometer according to Patent Document 1 is difficult to miniaturize, consumes a large amount of power, has a complicated circuit, and requires some expensive parts, which increases the overall cost. There are problems such as.

前記特許文献１に係る耳式体温計は、短時間期間中の１回体温測定には適しているが、長時間期間中の連続体温測定には適していない。特殊な使用条件、例えば、手術中の被施術者の体温測定等においては、手術前の準備段階において十分な時間が取れるので、ある程度の立ち上がり時間（約１０分程度）を無視できること、大きな相対温度および早い温度変化を無視できること（最大で１０分間に１℃の温度変化を感知できればよい）、連続して測定する必要があること、環境温度が比較的安定していることなどの使用条件においては、前記特許文献１に係る耳式体温計は高価で適切ではない。   The ear thermometer according to Patent Document 1 is suitable for one-time body temperature measurement during a short time period, but is not suitable for continuous body temperature measurement during a long time period. In special usage conditions, such as measuring the body temperature of the patient during surgery, sufficient time is available in the preparation stage before surgery, so that a certain amount of rise time (about 10 minutes) can be ignored, and a large relative temperature Under conditions of use such as ignoring rapid temperature changes (if it can detect a temperature change of 1 ° C for a maximum of 10 minutes), having to measure continuously, and having a relatively stable ambient temperature The ear thermometer according to Patent Document 1 is expensive and not appropriate.

そこで、本出願人は、測温対象者の体温を長時間期間中連続測定でき、しかも安価で使い捨て可能な耳式体温計を得るために、次に続く特許出願（特許文献２参照）において、測定装置に連結されるプローブが本体部と、その本体部に結合された測温部とを含み、本体部は、ほぼＬ字形円筒体に形成され、一端がケーブルを介して前記測定装置に接続され、他端が前記測温部に結合され、測温部は、本体部に結合するフランジ部分、フランジ部分から延びる先端部分を含み、先端部分の内部にセンサミラーが嵌め込まれ、センサミラーは、内部に凹形状反射面を有する円筒体ホルダ、その円筒体ホルダの後方から延びる連結軸、円筒体ホルダの前面空間にリード線で支持された測温用の第１センサおよび補正用の第２センサ、円筒体ホルダの前面を覆う保護カバーを含み、第１および第２センサを支持する各リード線が測温部および本体部を貫通してケーブルに電気的に接続されている耳式体温計を提案した。   Therefore, in order to obtain an ear-type thermometer that can continuously measure the body temperature of the temperature measurement subject for a long period of time and is inexpensive and disposable, the present applicant measured in the following patent application (see Patent Document 2). The probe connected to the apparatus includes a main body part and a temperature measuring part coupled to the main body part. The main body part is formed in a substantially L-shaped cylindrical body, and one end is connected to the measuring apparatus via a cable. The other end is coupled to the temperature measuring unit, and the temperature measuring unit includes a flange portion coupled to the main body portion, a tip portion extending from the flange portion, and a sensor mirror is fitted inside the tip portion. A cylindrical holder having a concave reflective surface, a connecting shaft extending from the rear of the cylindrical holder, a first sensor for temperature measurement supported by a lead wire in the front space of the cylindrical holder, and a second sensor for correction, Of cylindrical holder It includes a protective cover for covering the surface and through each lead wire temperature measuring unit and the main body portion for supporting the first and second sensors proposed ear thermometer that is electrically connected to the cable.

前記特許文献２に係る耳式体温計においては、プローブに使用されるサーミスタが精度を保つ温度範囲は、測温対象者の体温変化範囲のみでよく、従来のサーモパイルを用いた耳式体温計のように、測定環境温度範囲全域においてサーミスタの測定精度を保つ必要がない。比較的安定した環境温度の下では、長時間期間中の連続測定が可能となる。測温回路が単純化され、温度校正が簡略化され、プローブが小型化され、量産時の組立が容易になり、小型で安価な耳式体温計が得られる。従って、前記特許文献２に係る耳式体温計は使い捨てが可能になり、測温対象者の耳への装着が安定確実になるので、特に手術中の被施術者の体温測定に最適である。   In the ear thermometer according to Patent Document 2, the temperature range in which the thermistor used for the probe maintains accuracy is only the body temperature change range of the temperature measurement subject, as in a conventional ear thermometer using a thermopile. This eliminates the need to maintain thermistor measurement accuracy over the entire temperature range. Under a relatively stable ambient temperature, continuous measurement during a long period of time is possible. The temperature measurement circuit is simplified, temperature calibration is simplified, the probe is miniaturized, assembly during mass production is facilitated, and a small and inexpensive ear-type thermometer is obtained. Therefore, since the ear-type thermometer according to Patent Document 2 can be disposable and can be stably and reliably attached to the ear of the temperature-measuring subject, the ear-type thermometer is particularly suitable for measuring the temperature of the subject during surgery.

しかしながら、前記特許文献２に係る耳式体温計においては、第１および第２センサがリード線によってセンサミラー内に支持される構造になっているので、センサとリード線とを半田付けする作業、センサをセンサミラー内に設置する作業に高度の熟練と時間を要し、量産に適していないことがわかった。

Japanese Patent Laying-Open No. 2006-250883 (Japanese Patent Application No. 2005-071350) JP 2007-111363 A (Japanese Patent Application No. 2005-307672)

本考案は、前記特許文献２に係る耳式体温計において、センサをセンサミラー内に容易に設置できる構造を提供して、耳式体温計の量産化を図ることを課題としている。   An object of the present invention is to provide a structure in which a sensor can be easily installed in a sensor mirror in the ear thermometer according to Patent Document 2 to achieve mass production of the ear thermometer.

本考案に基づく耳式体温計は、測定装置に連結されるプローブを備えた耳式体温計であって、プローブが本体部とおよびその本体部に結合された測温部とを含む。本体部は、ほぼＬ字形円筒体に形成され、一端がケーブルを介して測定装置に接続され、他端が測温部に結合される。測温部は、本体部に結合するフランジ部分とおよびそのフランジ部分から延びる先端部分とを含み、先端部分の内部にセンサミラーが嵌め込まれる。センサミラーは、内部に凹形状反射面を有する円筒体ホルダと、その円筒体ホルダの後方から延びる連結軸と、所定パターンの回路導体を有しかつ円筒体ホルダの前面空間に張り渡された可撓性印刷回路基板と、その基板の長手方向に所定の間隔を空けて基板上の回路導体に半田付けされた測温用の第１センサおよび補正用の第２センサと、円筒体ホルダの前面を覆う保護カバーとを含む。可撓性印刷回路基板が測温部内で本体部を貫通したケーブルの一端に電気的に接続される。   The ear-type thermometer based on this invention is an ear-type thermometer provided with the probe connected with a measuring apparatus, Comprising: A probe includes a main-body part and the thermometer part couple | bonded with the main-body part. The main body is formed in a substantially L-shaped cylindrical body, one end is connected to the measuring device via a cable, and the other end is coupled to the temperature measuring unit. The temperature measuring part includes a flange part coupled to the main body part and a tip part extending from the flange part, and a sensor mirror is fitted inside the tip part. The sensor mirror includes a cylindrical holder having a concave reflecting surface therein, a connecting shaft extending from the rear of the cylindrical holder, a circuit conductor having a predetermined pattern, and is stretched over the front space of the cylindrical holder. A flexible printed circuit board, a first sensor for temperature measurement and a second sensor for correction soldered to a circuit conductor on the board at a predetermined interval in the longitudinal direction of the board, and the front surface of the cylindrical holder And a protective cover for covering. A flexible printed circuit board is electrically connected to one end of a cable penetrating the main body in the temperature measuring unit.

センサミラーの外周面中間部分のほぼ対向部位に第１突起および第２突起を設け、可撓性印刷回路基板の一端側で第１突起および第２突起にそれぞれ対応する部位に第１位置決め穴および第２位置決め穴を設けることが好ましい。第１および第２突起を第１および第２位置決め穴にそれぞれ係合させ、可撓性印刷回路基板の他端側をセンサミラーの外周面上を長手方向に沿って誘導し、基板の他端側を測温部内で本体部を貫通したケーブルの一端に電気的に接続することができる。   A first protrusion and a second protrusion are provided at substantially opposite positions of the middle portion of the outer peripheral surface of the sensor mirror, and the first positioning hole and the first protrusion hole are formed at positions corresponding to the first protrusion and the second protrusion on one end side of the flexible printed circuit board, respectively. It is preferable to provide a second positioning hole. The first and second protrusions are engaged with the first and second positioning holes, respectively, and the other end of the flexible printed circuit board is guided along the longitudinal direction on the outer peripheral surface of the sensor mirror. The side can be electrically connected to one end of a cable penetrating the main body in the temperature measuring section.

円筒体ホルダの前面空間に張り渡された可撓性印刷回路基板の中間部分に赤外線透過用穴を設け、その赤外線透過用穴の両側でかつ基板の長手方向に第１センサおよび第２センサを配置することが好ましい。   An infrared transmission hole is provided in an intermediate portion of the flexible printed circuit board stretched over the front space of the cylindrical holder, and the first sensor and the second sensor are provided on both sides of the infrared transmission hole and in the longitudinal direction of the substrate. It is preferable to arrange.

円筒体ホルダの前面空間に張り渡された可撓性印刷回路基板の中間部分において、その基板の一端側に熱溜まり導体を設けることが好ましい。   In an intermediate portion of the flexible printed circuit board stretched over the front space of the cylindrical holder, it is preferable to provide a heat accumulation conductor on one end side of the board.

本考案に基づく耳式体温計においては、プローブに使用されるセンサ（サーミスタ）が精度を保つ温度範囲は、測温対象者の体温変化範囲のみでよく、従来のサーモパイルを用いた耳式体温計のように、測定環境温度範囲全域においてサーミスタの測定精度を保つ必要がない。比較的安定した環境温度の下では、長時間期間中の連続測定が可能となる。センサを可撓性印刷回路基板の回路導体に予め半田付けできるので、組立作業が簡略化され、量産に適している。さらに、測温回路が単純化され、温度校正が簡略化され、プローブが小型化され、小型で安価な耳式体温計が得られる。従って、本考案に基づく耳式体温計は使い捨てが可能になり、測温対象者の耳への装着が安定確実になるので、特に手術中の被施術者の体温測定に最適である。   In the ear-type thermometer based on the present invention, the temperature range in which the sensor (thermistor) used for the probe maintains accuracy is limited to the temperature change range of the temperature-measurement target, like an ear-type thermometer using a conventional thermopile. In addition, it is not necessary to maintain thermistor measurement accuracy over the entire measurement environment temperature range. Under a relatively stable ambient temperature, continuous measurement during a long period of time is possible. Since the sensor can be pre-soldered to the circuit conductor of the flexible printed circuit board, the assembly work is simplified and suitable for mass production.

本考案に基づく耳式体温計１のプローブ２は、図３−８に示すように、本体部２１、本体部２１に連結された測温部２２、本体部２１の外側にそって設けられたタブ２３を含む。本体部２１は、長辺部分２１１と屈曲短辺部分２１２からなるほぼＬ字形に屈曲した円筒体に形成される。長辺部分２１１が測温対象者９（図１）の耳孔９ａの下方から顔面こめかみ付近にそって延び、屈曲短辺部分２１２が測温部２２の後述するフランジ部分２２１に結合する。この概略Ｌ字形形状は、測温部２２の先端部分２２２を測温対象者９の耳孔９ａ内で鼓膜側に向けると共に、装着時に本体部２１が耳介から脱落または耳介上で回転しないようにする。本体部２１の下端からはケーブル３が延びていて、後述する第１センサ２５および第２センサ２６を装着した可撓性印刷回路基板２４６を雄コネクタ４に電気的に接続する。タブ２３は、プローブ２を測温対象者９の耳孔９ａに着脱するさいに作業を容易にするために設けられている。   As shown in FIGS. 3-8, the probe 2 of the ear thermometer 1 according to the present invention includes a main body part 21, a temperature measuring part 22 connected to the main body part 21, and a tab provided along the outside of the main body part 21. 23. The main body 21 is formed in a cylindrical body that is bent in a substantially L shape, which includes a long side portion 211 and a bent short side portion 212. The long side portion 211 extends along the vicinity of the face temple from below the ear hole 9a of the temperature measuring subject 9 (FIG. 1), and the bent short side portion 212 is coupled to a flange portion 221 described later of the temperature measuring portion 22. This generally L-shaped shape directs the tip portion 222 of the temperature measuring unit 22 toward the eardrum in the ear canal 9a of the temperature measuring subject 9, and prevents the main body portion 21 from falling off the auricle or rotating on the auricle when worn. To. The cable 3 extends from the lower end of the main body 21, and a flexible printed circuit board 246 equipped with a first sensor 25 and a second sensor 26 described later is electrically connected to the male connector 4. The tab 23 is provided to facilitate the work when the probe 2 is attached to and detached from the ear hole 9a of the temperature measuring subject 9.

測温部２２は、本体部２１の屈曲短辺部分２１２に結合するフランジ部分２２１、フランジ部分２２１から延びる先端部分２２２を含む。フランジ部分２２１は耳孔９ａの入口を閉じるように形成され、また、先端部分２２２は外耳道の複雑な形状に合わせるように形成される。   The temperature measuring unit 22 includes a flange portion 221 coupled to the bent short side portion 212 of the main body portion 21 and a tip end portion 222 extending from the flange portion 221. The flange portion 221 is formed so as to close the entrance of the ear canal 9a, and the tip portion 222 is formed so as to conform to the complicated shape of the ear canal.

プローブ２を構成する本体部２１、測温部２２、タブ２３、センサミラー２４は断熱性材料から作られる。測温部２２は、測温対象者９のアレルギ体質を考慮して、エラストマまたはシリコンゴムで被覆することが好ましい。   The main body 21, the temperature measuring unit 22, the tab 23, and the sensor mirror 24 constituting the probe 2 are made of a heat insulating material. The temperature measuring unit 22 is preferably covered with an elastomer or silicon rubber in consideration of the allergic constitution of the temperature measurement subject 9.

前述したように、本考案に基づく耳式体温計１のプローブ２は、本体部２１、測温部２２、タブ２３を含む。測温部２２は、フランジ部分２２１、先端部分２２２を含む。図３に示すように、測温部２２の先端部分２２２の内部にセンサミラー２４が嵌め込まれる。センサミラー２４は、例えば、平行光集光型センサミラー（図３参照）または点光源集光型センサミラー（図４参照）のいずれでもよい。平行光集光型センサミラーは、円筒体ホルダの前面の平行光をセンサに集光する。点光源集光型センサミラーは、鼓膜想定位置の点光源からの光を集光する。センサミラー２４は、各センサ２５、２６の組付け作業を容易にするために、測温部２２とは別部品としている。   As described above, the probe 2 of the ear thermometer 1 according to the present invention includes the main body portion 21, the temperature measuring portion 22, and the tab 23. The temperature measuring unit 22 includes a flange portion 221 and a tip portion 222. As shown in FIG. 3, the sensor mirror 24 is fitted inside the distal end portion 222 of the temperature measuring unit 22. The sensor mirror 24 may be, for example, either a parallel light condensing sensor mirror (see FIG. 3) or a point light source condensing sensor mirror (see FIG. 4). The parallel light condensing sensor mirror condenses parallel light on the front surface of the cylindrical holder on the sensor. The point light source condensing sensor mirror condenses light from the point light source at the assumed eardrum position. The sensor mirror 24 is a separate component from the temperature measuring unit 22 in order to facilitate the assembly work of the sensors 25 and 26.

センサミラー（点光源集光型センサミラー）２４は絶縁性材料から作られ、図４に示すように、内部に凹形状反射面２４１を有する比較的長尺の円筒体ホルダ２４２、ホルダ２４２の後方から延びる連結軸２４５、ホルダ２４２の前面に張り渡された後述する可撓性印刷回路基板２４６、基板２４６に装着された後述する測温用の第１センサ２５および補正用の第２センサ２６、ホルダ前面を覆う保護カバー２７を含む。   The sensor mirror (point light source condensing type sensor mirror) 24 is made of an insulating material and has a relatively long cylindrical holder 242 having a concave reflecting surface 241 inside, as shown in FIG. A connecting shaft 245 extending from the front surface of the holder 242, a flexible printed circuit board 246, which will be described later, a first sensor 25 for measuring temperature and a second sensor 26, which will be described later, mounted on the board 246, A protective cover 27 covering the front surface of the holder is included.

センサミラー２４の反射面２４１は、素材の鏡面仕上げのままにするか、さらにその上に金属（例えば、アルミニウム）箔を貼り付けるか、ニッケルメッキを施すことが好ましい。保護カバー２７は、放射エネルギ損失を抑え、センサ２５、２６を保護する材料であればよい。例えば、厚み０．０１５ｍｍのポリエチレン・フィルムが好ましい。保護カバー２７は、センサミラー２４の円筒体ホルダ２４２および連結軸２４５の外周面と測温部２２の先端部分２２２の穴内周面との間に押し込まれて固定される。   The reflective surface 241 of the sensor mirror 24 is preferably left as a mirror finish of the material, or a metal (for example, aluminum) foil is further applied thereon, or nickel plating is performed. The protective cover 27 may be any material that suppresses radiant energy loss and protects the sensors 25 and 26. For example, a polyethylene film having a thickness of 0.015 mm is preferable. The protective cover 27 is pushed and fixed between the outer peripheral surface of the cylindrical body holder 242 and the connecting shaft 245 of the sensor mirror 24 and the inner peripheral surface of the hole of the tip portion 222 of the temperature measuring unit 22.

可撓性印刷回路基板２４６は、図５に示すように、可撓性絶縁材料（例えば、ポリエチレン等）からなる細長フィルムであって、その表面に回路導体２４６ｄおよび熱溜まり２４６ｅが印刷され、さらに赤外線透過穴２４６ｃ、第１位置決め穴２４６ａ、第２位置決め穴２４６ｂが貫通されている。これらの作用については後述する。   As shown in FIG. 5, the flexible printed circuit board 246 is an elongated film made of a flexible insulating material (for example, polyethylene), on which a circuit conductor 246d and a heat reservoir 246e are printed, The infrared transmission hole 246c, the first positioning hole 246a, and the second positioning hole 246b are penetrated. These actions will be described later.

図４、６−８に示すように、センサミラー２４の円筒体ホルダ２４２の外周面中間部分のほぼ対向部位に第１突起２４２ａおよび第２突起２４２ｂが設けられる。図５に示すように、可撓性印刷回路基板２４６の一端側で第１突起２４２ａおよび第２突起２４２ｂにそれぞれ対応する部位に第１位置決め穴２４６ａおよび第２位置決め穴２４６ｂが設けられる。第１突起２４２ａおよび第２突起２４２ｂが第１位置決め穴２４６ａおよび第２位置決め穴２４６ｂにそれぞれ係合される。このようにして、可撓性印刷回路基板２４６の一端側は、センサミラー２４の円筒体ホルダ２４２の前面空間に簡単に張り渡される。   As shown in FIGS. 4 and 6-8, a first protrusion 242a and a second protrusion 242b are provided at substantially opposite positions of the intermediate portion of the outer peripheral surface of the cylindrical body holder 242 of the sensor mirror 24. As shown in FIG. 5, a first positioning hole 246 a and a second positioning hole 246 b are provided at portions corresponding to the first protrusion 242 a and the second protrusion 242 b on one end side of the flexible printed circuit board 246. The first protrusion 242a and the second protrusion 242b are engaged with the first positioning hole 246a and the second positioning hole 246b, respectively. In this way, one end of the flexible printed circuit board 246 is easily stretched over the front space of the cylindrical holder 242 of the sensor mirror 24.

可撓性印刷回路基板２４６の他端側がセンサミラー２４の円筒体ホルダ２４２の外周面上を長手方向に沿って誘導され、基板２４６の他端側を本体部２１の先端に埋め込まれた連結基板２１３に接続される。図３に示すように、各センサ２５、２６を装着した可撓性印刷回路基板２４６の他端は、連結基板２１３を介してケーブル３の先端に接続される。このようにして、可撓性印刷回路基板２４６は、測温部２２内で本体部２１の内部を貫通するケーブル３に電気的に接続される。   The other end side of the flexible printed circuit board 246 is guided along the longitudinal direction on the outer peripheral surface of the cylindrical holder 242 of the sensor mirror 24, and the other end side of the board 246 is embedded in the front end of the main body 21. 213 is connected. As shown in FIG. 3, the other end of the flexible printed circuit board 246 on which the sensors 25 and 26 are mounted is connected to the tip of the cable 3 via a connection board 213. In this way, the flexible printed circuit board 246 is electrically connected to the cable 3 penetrating the inside of the main body 21 within the temperature measuring unit 22.

図４、６−８に示すように、可撓性印刷回路基板２４６の一端側は円筒体ホルダ２４２の前面空間に張り渡される。図５に示すように、円筒体ホルダ２４２の前面空間に張り渡される予定部位に相当する可撓性印刷回路基板２４６の中間部分に赤外線透過用穴２４６ｃが設けられる。その赤外線透過用穴２４６ｃの両側でかつ基板２４６の長手方向に第１センサ２５および第２センサ２６が配置される。可撓性印刷回路基板２４６が円筒体ホルダ２４２の前面空間に張り渡される以前に、センサ２５、２６は予め基板２４６の回路導体２４６ｄに半田付けされる。このようにすれば、センサ２５、２６をセンサミラー２４に装着することが容易になり、高度の技術を必要とせず、測温部２２を量産化することができる。測温対象者９からの赤外線は基板２４６の赤外線透過穴２４６ｃを通過し、センサミラー２４の反射面２４１で反射され、センサ２５、２６に至る。   As shown in FIGS. 4 and 6-8, one end side of the flexible printed circuit board 246 is stretched over the front space of the cylindrical holder 242. As shown in FIG. 5, an infrared transmission hole 246 c is provided in an intermediate portion of the flexible printed circuit board 246 corresponding to a planned portion that is stretched over the front space of the cylindrical holder 242. The first sensor 25 and the second sensor 26 are disposed on both sides of the infrared transmission hole 246 c and in the longitudinal direction of the substrate 246. Before the flexible printed circuit board 246 is stretched over the front space of the cylindrical holder 242, the sensors 25 and 26 are previously soldered to the circuit conductor 246d of the board 246. In this way, it becomes easy to attach the sensors 25 and 26 to the sensor mirror 24, and the temperature measuring unit 22 can be mass-produced without requiring a high level of technology. Infrared rays from the temperature measurement subject 9 pass through the infrared transmission hole 246 c of the substrate 246, are reflected by the reflection surface 241 of the sensor mirror 24, and reach the sensors 25 and 26.

また、図５に示すように、円筒体ホルダ２４２の前面空間に張り渡される予定部位に相当する可撓性印刷回路基板２４６の中間部分において、その基板２４６の一端側に熱溜まり導体２４６ｅを設けることが好ましい。熱溜まり導体２４６ｅは、基板２４６に到達する赤外線を吸収し、センサ２５、２６への二次的熱影響を防止する。   Further, as shown in FIG. 5, a heat accumulation conductor 246e is provided on one end side of the flexible printed circuit board 246 corresponding to a planned portion to be stretched over the front space of the cylindrical holder 242 on one end side of the board 246. It is preferable. The heat accumulation conductor 246e absorbs infrared rays reaching the substrate 246 and prevents a secondary heat influence on the sensors 25 and 26.

示度試験の結果、プローブ２の示度は外気温度によって影響を受けることがわかった。そこで、測温用のセンサ（第１センサ２５）の外に別のセンサ（第２センサ２６）を設けて、外気温度の影響を補正している。   As a result of the reading test, it was found that the reading of the probe 2 is influenced by the outside air temperature. Therefore, another sensor (second sensor 26) is provided outside the temperature measuring sensor (first sensor 25) to correct the influence of the outside air temperature.

第１センサ２５および第２センサ２６には、小熱容量、高熱感受性、高赤外線反応温度上昇率等の特性を備えたサーミスタ素子が適している。   For the first sensor 25 and the second sensor 26, a thermistor element having characteristics such as a small heat capacity, high heat sensitivity, and a high infrared reaction temperature rise rate is suitable.

実験の結果、センサミラー２４の円筒体ホルダ２４２の前面空間に張り渡された可撓性印刷回路基板２４６上には、集光点が一番高くなる温度分布が現れることを確認した。そこで、測温用の第１センサ２５は、図４に示すように、センサミラー２４の反射面２４１のほぼ集光点に配置される。外気温度補正用の第２センサ２６は、集光点から外れた位置に配置される。センサ２５、２６は同一基板上にあるので、ほぼ同時に昇温し、補正がより簡単になっている。第１センサ２５には、放射率が高く（赤外線を良く吸収し発熱する）、赤外線により発生した熱を発散し易い樹脂（例えば、黒色熱硬化性のエポキシ樹脂）が塗布される。第２センサ２６には、赤外線を吸収し難い樹脂（例えば、２液硬化型エポキシ樹脂）が塗布される。   As a result of the experiment, it was confirmed that a temperature distribution with the highest condensing point appeared on the flexible printed circuit board 246 stretched over the front space of the cylindrical holder 242 of the sensor mirror 24. Therefore, as shown in FIG. 4, the first temperature sensor 25 for temperature measurement is disposed at a substantially condensing point on the reflection surface 241 of the sensor mirror 24. The second sensor 26 for correcting the outside air temperature is arranged at a position deviating from the condensing point. Since the sensors 25 and 26 are on the same substrate, the temperature is raised almost at the same time, making correction easier. The first sensor 25 is coated with a resin (for example, a black thermosetting epoxy resin) that has a high emissivity (it absorbs infrared rays well and generates heat) and easily radiates heat generated by the infrared rays. The second sensor 26 is coated with a resin that hardly absorbs infrared rays (for example, a two-component curable epoxy resin).

第１センサ２５および第２センサ２６を同時に温度校正（較正）する。この校正については、前記特許文献２において詳述されているので、省略する。   The first sensor 25 and the second sensor 26 are simultaneously temperature calibrated (calibrated). Since this calibration is described in detail in Patent Document 2, it is omitted here.
