Description
本発明は、被測温者の体温測定を正確かつ容易に行い、測温者の負荷を軽減可能な温度測定送受信装置に関する。 The present invention relates to a temperature measurement transmission / reception apparatus capable of accurately and easily measuring a temperature of a temperature-measured person and reducing a load on the temperature-measured person.
生命の維持に直結する体温、心拍、呼吸、血圧などは、特に総称して生命徴候(バイタルサイン)と呼ばれ、生命徴候が一定の値(正常値)で安定していれば、生命の制御がうまく働いていると見なされ、逆に不安定ならば、正常な健康状態でないことが分かる。従って、病院では、日常的に入院患者の体温を測定する必要性がある。 Body temperature, heart rate, respiration, blood pressure, etc., which are directly linked to the maintenance of life, are collectively called vital signs (vital signs). If vital signs are stable at a constant value (normal value), life control Is considered to be working well, and if it is unstable, it indicates that it is not in a normal state of health. Therefore, in hospitals, there is a need to measure the temperature of hospitalized patients on a daily basis.
水銀式又は、電子式体温計のいずれかを使用して、予め決められた時間に看護士が巡回し、入院患者に体温計を配布し、入院患者自らがわきの下に密着し、一定時間後に看護士が巡回して各入院患者から体温計を回収し、測温結果を読み取り、記録簿に記入していく。更に、入院患者のすべて回った後、回収した体温計をすべて消毒し、前期記録簿に記入した測温結果をパソコンにインプットして行く必要がある。
しかしながら、上記背景技術には以下のような問題が発生した。 However, the following problems have occurred in the background art.
ほとんどの病院では、入院患者の健康状態を逐一確認するため、朝、昼、晩の1日に3回検温する。通常、入院患者全員に体温測定を行い、温度データをとり、それを記録する。 In most hospitals, temperature is measured three times a day in the morning, noon and evening to confirm the health status of the inpatient. Usually, all inpatients are measured for body temperature, temperature data is taken and recorded.
体温に用いられる水銀式は、検温に非常に多くの時間を費やす必要があり、又、電子式体温計は検温時間の短縮のため、予測型が主流であり、最終的に安定する平衡温を推測するため、肌に密着させないと誤差の影響が大きい。 The mercury type used for body temperature needs to spend a great deal of time for temperature measurement, and the electronic thermometer is mainly used for prediction to reduce the time required for temperature measurement. Therefore, the effect of error is large unless it is in close contact with the skin.
記録する作業は、氏名、体温、日時(時間)の順で、記録用紙に、鉛筆などを使用して、患者全員のデータを正確に記録しなくてはいけない。検温する作業に、この記録する作業が同時に加わり、測温者の看護士にとって、煩雑な作業となっている。また、同時に被測温者の入院患者にとっても、負荷のかかる作業になっている。 For the recording work, the data of all the patients must be recorded accurately using a pencil or the like on the recording paper in the order of name, body temperature, date and time (time). This recording work is added to the work of measuring the temperature at the same time, which is a complicated work for the nurse of the thermometer. At the same time, it is a burdensome work for the hospitalized patient of the person to be measured.
測温作業以外にも記録する作業として、患者毎に、1日3回記録した体温について、履歴として電気的なデータとしてパソコン保存したり、時間的な体温の変化をグラフ表示させたりするためには、看護士が測温データをキーボード入力する必要があり、時間がかかる作業であり、看護士の負荷を増加させる。 In addition to the temperature measurement work, to record the body temperature recorded three times a day for each patient, to save it as electrical data as a history, and to display a temporal change in body temperature as a graph This is a time-consuming operation that requires a nurse to input temperature measurement data on the keyboard, and increases the burden on the nurse.

温度センサ25は、粘着パッド内で肌に密着されており、通常の予測型と異なり、長時間、肌に密着している。推測する時間も必要とせずに、本当の体温を測定することが出来る。従って、測定による誤差が少ない。 The temperature sensor 25 is in close contact with the skin in the adhesive pad, and is in close contact with the skin for a long time, unlike a normal prediction type. Real body temperature can be measured without requiring time to guess. Therefore, there is little error due to measurement.
以下、図1の動作を図3のフローチャートに基づき説明する。 The operation of FIG. 1 will be described below based on the flowchart of FIG.
まず、リーダ2の操作スイッチ12を粘着パッド1の近くでONし、リーダ2のRFドライバ16において発生した共振波形をアンテナ18より、10mW程度の微弱無線を出力する(ステップS1)。 First, the operation switch 12 of the reader 2 is turned on near the adhesive pad 1, and the resonance waveform generated in the RF driver 16 of the reader 2 is output from the antenna 18 as weak radio of about 10 mW (step S1).
一方、微弱無線の出力を受けたICチップ6のRF部ではキャリアを整流して電源電圧VDDを自励発電し、自励発電されたVDDをICチップ6全体に供給する(ステップS2)。 On the other hand, in the RF part of the IC chip 6 that has received the weak wireless output, the carrier is rectified and the power supply voltage VDD is self-excited, and the self-excited power VDD is supplied to the entire IC chip 6 (step S2).
温度センサ25は人の体温によって敏感に変化するサーミスタからなり、サーミスタの抵抗値を電圧変換しA/D24に送り、A/D24はアナログ値である電圧レベルをデジタル値に変換し、前期のデジタル値をCPU20へ出力する(ステップS3)。 The temperature sensor 25 is a thermistor that changes sensitively depending on the body temperature of the person. The resistance value of the thermistor is converted into a voltage and sent to the A / D 24. The A / D 24 converts the analog voltage level into a digital value. The value is output to the CPU 20 (step S3).
CPU20は、前記デジタル値のデータを得て、CPU20のレジスタに一時保持し、CPU20は、前記の内部レジスタに一時保持したデータおよび、予め用意されているEEPROM内にある識別IDコードを付けて、RF部21へデジタルデータを出力する(ステップS4)。 The CPU 20 obtains the data of the digital value and temporarily stores it in the register of the CPU 20, and the CPU 20 attaches the data temporarily stored in the internal register and the identification ID code in the EEPROM prepared in advance. Digital data is output to the RF unit 21 (step S4).
RF部21は、前期デジタルデータを無線データに変換し、アンテナ22より無線出力する。(ステップS5)
引き続き、リーダ2は、アンテナ18を通じてRF受信回路17において、ICチップ6からのデータを受信し、RF受信回路17は、データをデジタル値に変換し、CPU10へ出力する(ステップS6)。
The RF unit 21 converts the previous period digital data into wireless data and wirelessly outputs it from the antenna 22. (Step S5)
Subsequently, the reader 2 receives the data from the IC chip 6 in the RF receiving circuit 17 through the antenna 18, and the RF receiving circuit 17 converts the data into a digital value and outputs it to the CPU 10 (step S6).
CPU10では、前記のデジタル値に、現在の時刻情報を付加し、メモリ15に保存する(ステップS7)。 The CPU 10 adds the current time information to the digital value and stores it in the memory 15 (step S7).
これで被測温者1人の検温から記録が終了し、非測温者が全て終了したか否かが判定される(ステップS8)。 Thus, the recording is completed from the temperature measurement of one temperature-measured person, and it is determined whether all the non-temperature-measured persons have been completed (step S8).
すべての被測温者の検温が終了した場合には、測温作業は終了とし、終了していない場合には、S1に戻り、次の被測温者の測定を行い、残りの被測温者の人数分S1〜S8を繰り返すことになる。 When the temperature measurement of all the temperature-measured persons is completed, the temperature measurement operation is terminated. If not completed, the process returns to S1, the next temperature-measured person is measured, and the remaining temperature-measured persons are measured. S1 to S8 are repeated for the number of persons.
