Description

本発明は複数の生体情報を含んだ体動信号を検出して個々の信号を識別して表示する生体計測装置に関する。  The present invention relates to a biological measurement apparatus that detects a body motion signal including a plurality of biological information, and identifies and displays each signal.

従来の生体計測装置においては生体から得た個々の信号を基に数値化して呼吸数、心拍数等を連続して表示するものがある。  Some conventional biological measuring devices digitize based on individual signals obtained from a living body and continuously display a respiratory rate, a heart rate, and the like.

従来の生体計測装置においては計測結果又は処理した結果を連続して表示することに主眼が置かれていたので、ノイズその他の原因で真の値から外れてもそのデータを計数し表示した。このため、明らかに不正確であるという場合は人の判断でエラーだと認識しているが、エラーであってもその度合いが低いと生理学的情報だと誤解してしまうという問題点があった。  In the conventional biological measuring apparatus, since the main focus is on continuously displaying the measurement result or the processed result, the data is counted and displayed even if it deviates from the true value due to noise or other causes. For this reason, when it is clearly inaccurate, it is recognized as an error by human judgment, but even if it is an error, there is a problem that it is misunderstood as physiological information if the degree is low .

複数の情報を含んだ体動信号を検出し、個々の信号を識別して表示する装置において、周期性信号に対して、周期又は単位時間あたりの頻度を数え、個々の信号ごとに設定する生理学的に妥当な数値を超えた値を計数したときは無視する機能をもつ処理部を具備している。  Physiology that sets the frequency for each periodic signal by counting the frequency per period or unit time with respect to the periodic signal in a device that detects body motion signals containing multiple information and identifies and displays each signal A processing unit having a function of ignoring when a value exceeding a reasonable numerical value is counted is provided.

周期性信号に対して、周期又は単位時間あたりの頻度を数え、所定回数たとえば5回の数値を用いて平均の頻度を算出する際に最大値と最小値を除いて計数する機能をもつ処理部を具備している。  A processing unit that counts the frequency per period or unit time for a periodic signal, and counts the maximum frequency and the minimum value when calculating the average frequency using a predetermined number of times, for example, 5 times. It has.

本発明は以上説明したような形態で実施し、算出結果が何らかの原因で事実とは異なる情報になった際は、連続した表示を停止することで表示しないようにする。このようにすることで、誤った情報で連続して表示するよりもたとえ一瞬間途切れても正確な情報を表示することが可能になる。具体的な効果を次に示す。  The present invention is implemented in the form as described above, and when the calculation result becomes information different from the fact for some reason, the display is stopped by stopping the continuous display. By doing in this way, it becomes possible to display accurate information even if it is interrupted for a moment rather than continuously displaying incorrect information. Specific effects are shown below.

数値列各要素の中に非生理学的数値がたとえば1個含まれている場合、単なる平均値では非生理的数値であることが容易にはわからない。しかし、生理学的数値範囲のチェック手段41を設けることにより、各要素たとえば7個の数値に対しすべてチェックをかけるので、算出した平均値の信憑性を格段に向上させることができる。  For example, when one non-physiological numerical value is included in each element of the numerical value string, it is not easy to know that a simple average value is a non-physiological numerical value. However, by providing the check means 41 for the physiological numerical value range, all the elements, for example, seven numerical values are checked, so that the credibility of the calculated average value can be remarkably improved.

さらに、非生理的数値が含まれる場合は表示しないので誤った情報を表示することはなく、信憑性の高い結果を得ているときだけ表示するので、その後の解釈や信号処理を正確にする。  Furthermore, since non-physiological numerical values are not displayed, incorrect information is not displayed, and only when a highly reliable result is obtained, the subsequent interpretation and signal processing are made accurate.

表示しない状態がある時間継続することは対象者が不在か、異常時を意味するので警報が出る。したがって、常時付き添いがなくても非常時には通報を得ることができる。  Continued for a certain period of time not displayed means that the subject is absent or abnormal, so an alarm is issued. Therefore, it is possible to obtain a report in an emergency even if there is no attendant at all times.

数値列がたとえ生理学的数値範囲内に収まっていた場合でも、たとえば7個のうち1個程度は装置上の都合、セッティングの都合等により他の数値とはかけ離れた数値を出すことがある。この場合平均値を採るとこのようなかけ離れた数値がデータの信憑性を低下させる。そこで、本発明では最大最小を除去する手段45を設けることにより、このような1個だけ極端にかけ離れた数値が合った場合でも除去することができるのでデータの信憑性を格段に向上させることができる。  Even if the numerical value sequence falls within the physiological numerical value range, for example, about one out of seven values may be different from other numerical values due to the convenience of the apparatus, the convenience of setting, and the like. In this case, when the average value is taken, such a far away numerical value reduces the credibility of the data. Therefore, in the present invention, by providing the means 45 for removing the maximum and minimum values, even if such a numerical value that is extremely different from one another can be removed, the credibility of the data can be remarkably improved. it can.

本発明の体動信号計測装置では、複数の情報を含んだ体動信号を検出し、個々の信号を識別して表示する装置において、周期性信号に対して、周期又は単位時間あたりの頻度を数え、個々の信号ごとに設定する生理学的に妥当な数値を超えた値を計数したときは無視する手段を設ける。  In the body motion signal measuring device of the present invention, a body motion signal including a plurality of information is detected, and in the device for identifying and displaying each signal, the frequency per cycle or unit time is determined with respect to the periodic signal. A means is provided for counting and ignoring when a value exceeding a physiologically valid value set for each signal is counted.

上記の生理学的に妥当な数値を超えた値を計数したときは無視する手段は、たとえば心臓の拍動に由来する体動信号成分について高い数値では180を超えることはないので180を超えると無視する判断部である。  The means for ignoring when a value exceeding the above physiologically valid value is counted is, for example, a high value for the body motion signal component derived from the heart beat, so it is ignored when it exceeds 180. It is a judgment part to do.

上記の判断部で低い数値については30より下がることはないので30以下になれば無視する。  In the above judgment unit, the lower numerical value never falls below 30, so it is ignored when it becomes 30 or less.

生体計測用の装置が周期的信号を計測する手段をもつ場合は一般にはたとえば5回の数値の移動平均処理を施して算出した値を表示する手段を採っている。本発明では上記所定の値を超えて無視することが5回中1回以上あれば平均値を表示しないようにする。  When the apparatus for measuring a living body has means for measuring a periodic signal, generally, for example, means for displaying a value calculated by performing a moving average process of five numerical values is adopted. In the present invention, the average value is not displayed if it exceeds the predetermined value and is ignored more than once in 5 times.

上記のように平均処理をする手段では、連続して5回妥当な範囲内数値を繰り返せば表示するようにする。  In the means for performing the averaging process as described above, if a numerical value within a valid range is repeated five times in succession, it is displayed.

また、5回の平均を採る際に極端に不適切な値を含むことがあり得るのでこれを避けるため最大値と最小値を除き、妥当な範囲3回分の移動平均を採る手段を設けてもよい。  In addition, when taking the average of 5 times, an extremely inappropriate value may be included, so in order to avoid this, means for taking a moving average for 3 reasonable ranges except for the maximum and minimum values may be provided. Good.

上記のように最大値と最小値を除く場合は移動平均処理数を増やしてよい。たとえば、7回分の数値から最大値と最小値を除き、残りの5回分の平均を採る手段を設けてもよい。  When the maximum value and the minimum value are excluded as described above, the number of moving average processes may be increased. For example, there may be provided means for removing the maximum value and the minimum value from the numerical values for seven times and taking the average of the remaining five times.

上記のように構成した装置を稼動すると、複数の情報を含んだ体動信号を検出し、個々の信号を識別して表示するときに、周期性信号に対して、周期又は単位時間あたりの頻度を数え、個々の信号ごとに設定する生理学的に妥当な数値を超えた値を計数したときは無視するようにはたらくか、最大値と最小値を無視するようにはたらくか、設定するので生理学的に妥当な数値やグラフを得ることができる。  When the apparatus configured as described above is operated, when a body motion signal including a plurality of information is detected, and individual signals are identified and displayed, the frequency per period or unit time with respect to the periodic signal Counts the value that exceeds the physiologically relevant value set for each individual signal, either ignores the value, or ignores the maximum and minimum values. A reasonable numerical value or graph can be obtained.

実施例について図面を参照して説明する。図1において、生体情報検出部1は複数の情報を含む体動情報を検出し、次の体動情報処理部2に送る。体動情報処理部2は複数の信号に分けるためnチャンネルに分岐して各情報を抽出する。数値検出部3では各チャンネルに特徴を意味する数値を算出する。計数処理部4は本発明であって、数値が妥当な範囲であれば表示部5に表示し、不自然な値であれば表示しないようにする手段である。かつ、計数処理部4は不自然な値のまま一定時間経過した場合は警報を発する手段を具備する。  Embodiments will be described with reference to the drawings. In FIG. 1, the biological information detection unit 1 detects body motion information including a plurality of information and sends it to the next body motion information processing unit 2. The body motion information processing unit 2 branches to n channels to extract each information in order to divide it into a plurality of signals. The numerical value detection unit 3 calculates a numerical value indicating a characteristic for each channel. The count processing unit 4 is the present invention, and is means for displaying on the display unit 5 if the numerical value is within a reasonable range and not displaying it if it is an unnatural value. In addition, the count processing unit 4 includes means for issuing an alarm when a certain time has passed with an unnatural value.

図1に示した実施例において体動情報処理部2はたとえばスペクトル分析、ピーク検出、周期検出等の手法を基本として構成し各チャンネルが担当する成分を検出する。  In the embodiment shown in FIG. 1, the body motion information processing unit 2 is configured based on techniques such as spectrum analysis, peak detection, period detection, and the like, and detects a component in charge of each channel.

図1に示した実施例において数値検出部3は各チャンネルに時系列に入ってくる数値列を周知の移動平均の手法で平均値を順次算出する。たとえばch1の呼吸由来体動であれば周期性信号が1分当たり約6〜15回程度である旨の数値を数秒おきに算出する。ch2の心拍由来体動であれば周期性信号が1分当たり約60回程度である旨の数値をほぼ1秒ごとに算出する。  In the embodiment shown in FIG. 1, the numerical value detection unit 3 sequentially calculates the average value of the numerical value sequence that enters the time series in each channel by a known moving average method. For example, in the case of ch1 respiratory-derived body motion, a numerical value indicating that the periodicity signal is about 6 to 15 times per minute is calculated every few seconds. For ch2 heartbeat-derived body motion, a numerical value indicating that the periodic signal is about 60 times per minute is calculated approximately every second.

図2に示した実施例は、計数処理部4の一つのチャンネルについて詳細実施例を示す。数値算出部3から数値列を受け取ると、生理学的数値範囲のチェック手段41によりチェックし、この範囲内であればyesの方へ送り、範囲外であればnoの方へ送る。  The embodiment shown in FIG. 2 shows a detailed embodiment for one channel of the counting processing unit 4. When the numerical value sequence is received from the numerical value calculation unit 3, it is checked by the physiological numerical value range checking means 41, and if it is within this range, it is sent to yes, and if it is outside this range, it is sent to no.

yesの方へ送った信号に対しては移動平均処理部42により平均値を順次算出し表示部5へ送る。  For the signal sent to yes, the moving average processing unit 42 sequentially calculates the average value and sends it to the display unit 5.

noの方へ送った信号に対しては表示除去処理部43により表示しないようする。  The display removal processing unit 43 does not display the signal sent to no.

noの方へ送った信号に対しては表示除去処理部43が動作して、ある一定時間継続する場合は警報部44により警報を発する。  The display removal processing unit 43 operates on the signal sent to no, and the alarm unit 44 issues an alarm when it continues for a certain period of time.

図3は図2で説明した計数処理部4に最大最小を除去する手段45を組み込んだ実施例である。この例のように、最大最小を除去する手段45の後段は生理学的数値範囲のチェック手段41を経由させるか否かについて選択できるようにした。  FIG. 3 shows an embodiment in which means 45 for removing the maximum / minimum is incorporated in the counting processing unit 4 described in FIG. As in this example, the latter stage of the means 45 for removing the maximum and minimum values can be selected as to whether or not to pass through the check means 41 of the physiological numerical range.
