Description

本発明は、脈拍計測装置を用いた安否確認通報システムに関する。 The present invention relates to a safety confirmation notification system using the pulse rate measuring device.

従来、脈拍検知を活用して安否確認を行うシステムが知られている（特許文献１参照。）。
特許文献１に記載されたシステムは、脈拍を測定する手段を備える安否確認装置を含み、脈拍の測定結果を活用して利用者の安否確認を行う。 Conventionally, a system for confirming safety by utilizing pulse detection is known (see Patent Document 1).
The system described in Patent Document 1 includes a safety confirmation device that includes a means for measuring a pulse, and confirms the safety of the user by using a measurement result of the pulse.

前記脈拍を測定する手段は、赤外線発光ダイオードから出る赤外線を血管に当てて、そこからの吸収量又は反射量の大小をフォトトランジスタで測定して脈拍の検知を行う。そのため、利用者が安静にしていない状態では前記赤外線の光軸がずれて脈波信号にノイズが乗ることとなり、脈拍を正確に測定できない問題がある。   The means for measuring the pulse applies the infrared light emitted from the infrared light emitting diode to the blood vessel and measures the amount of absorption or reflection from the blood vessel with a phototransistor to detect the pulse. Therefore, when the user is not at rest, the optical axis of the infrared rays is shifted and noise is added to the pulse wave signal, and there is a problem that the pulse cannot be measured accurately.

そこで、前記安否確認装置は、利用者の体の動きを測定する手段をさらに備え、利用者の体の動きがある場合には、当該利用者の体の動きの測定結果に基づいて安否を判定し、利用者の体の動きがない場合には、当該利用者の脈拍の測定結果に基づいて安否を判定している。   Therefore, the safety confirmation device further includes means for measuring the movement of the user's body, and when there is a movement of the user's body, the safety is determined based on the measurement result of the movement of the user's body. However, when there is no movement of the user's body, safety is determined based on the measurement result of the user's pulse.

しかしながら、前記安否確認装置は、脈拍を測定する手段と、利用者の体の動きを測定する手段とを備えるため、装置構成が複雑化する問題がある。   However, since the safety confirmation device includes means for measuring the pulse and means for measuring the movement of the user's body, there is a problem that the device configuration becomes complicated.

本発明で用いる脈拍計測装置１は、体導音検知手段２と、データ処理手段３と、表示手段４とを一体として備える。 <Pulse measurement device>
FIG. 1 is a block diagram showing an example of a pulse measuring device used in the present invention.
The pulse measuring device 1 used in the present invention is integrally provided with a body conduction sound detecting means 2, a data processing means 3, and a display means 4.

前記体導音検知手段２には、動脈音や心音を検知し、脈拍信号を取得する体導音センサ２１を用いる。ここで、本発明において、「脈拍」とは、「心拍」を含むものである。   The body conduction sound detection means 2 uses a body conduction sound sensor 21 that detects arterial sounds and heart sounds and acquires a pulse signal. Here, in the present invention, “pulse” includes “heartbeat”.

図２は、本発明で用いる脈拍計測装置で使用する体導音センサ２１の概略説明図を示す。
前記体導音センサ２１は、塩化ビニル製の円板２３上にエレクトレットコンデンサマイクロホン（ＥＣＭ）２２を貼り付け、該ＥＣＭ２２をアクリル製の円筒体２５に満たした充填剤２４で封止することで構成される。 FIG. 2 is a schematic explanatory diagram of the body conduction sound sensor 21 used in the pulse measuring device used in the present invention.
The body sound sensor 21 is configured by attaching an electret condenser microphone (ECM) 22 on a vinyl chloride disk 23 and sealing the ECM 22 with a filler 24 filled in an acrylic cylinder 25. Is done.

前記充填剤２４には、ソフトシリコンを用いることができる。前記充填剤２４にソフトシリコンを用いれば、気導音を遮断し体導音を抽出しやすくなる。   Soft silicon can be used for the filler 24. If soft silicon is used for the filler 24, air conduction sound is blocked and body conduction sound can be easily extracted.

前記データ処理手段３には、前記体導音センサ２１が取得する脈拍信号を自己相関処理して自己相関データを生成する信号処理部３１、前記信号処理部３１で生成される自己相関データに基づいて脈拍数を算出する脈拍数算出部３２を有するマイコン等のコンピュータを用いる。   The data processing unit 3 includes a signal processing unit 31 that generates autocorrelation data by performing autocorrelation processing on the pulse signal acquired by the body conduction sensor 21, and autocorrelation data generated by the signal processing unit 31. A computer such as a microcomputer having a pulse rate calculation unit 32 for calculating the pulse rate is used.

前記脈拍数算出部３２は、例えば前記自己相関データにおけるピークの周期を求めたり、前記自己相関データの値が事前に設定した閾値を超える回数をカウントしたりする等して脈拍数を算出することができる。   The pulse rate calculation unit 32 calculates the pulse rate by, for example, obtaining a peak period in the autocorrelation data or counting the number of times that the autocorrelation data value exceeds a preset threshold value.

前記表示手段４には、前記脈拍数算出部３２で算出する脈拍数等を表示するために液晶ディスプレイ等を用いる。   The display means 4 uses a liquid crystal display or the like to display the pulse rate calculated by the pulse rate calculation unit 32.

図１に示す脈拍計測装置１は、体導音検知手段２と、データ処理手段３と、表示手段４とを一体として備えるため、例えば手首装着型（腕時計型）に適する。 The pulse measuring device 1 shown in FIG. 1 is suitable for, for example, a wrist-worn type (watch type) because it includes the body conduction sound detecting means 2, the data processing means 3, and the display means 4 as one body.

次に、図３は、本発明で用いる脈拍計測装置の他の例を示すブロック図である。
図３に示す脈拍計測装置１１は、体導音検知手段１２と、データ処理手段１３及び表示手段１４とが別体とされる点で、図１に示す脈拍計測装置１と異なる。 Next, FIG. 3 is a block diagram showing another example of a pulse measuring device used in the present invention.
The pulse measuring device 11 shown in FIG. 3 is different from the pulse measuring device 1 shown in FIG. 1 in that the body conduction sound detecting means 12, the data processing means 13, and the display means 14 are separated.

そして、図３に示す脈拍計測装置１１は、前記体導音検知手段１２に送信機２６、前記データ処理手段１３に受信機３３がそれぞれ設けられ、前記体導音検知手段１２が取得した脈拍信号を無線通信手段により前記データ処理手段１３に送信する構成とされている。 3 is provided with a transmitter 26 in the body conduction sound detection means 12 and a receiver 33 in the data processing means 13, and the pulse signal obtained by the body conduction sound detection means 12 is provided.

図３に示す脈拍計測装置１１は、前記体導音検知手段１２が、データ処理手段１３及び表示手段１４と独立した構造であるため、利用者が手首や頸部、胸部等の動脈音又は心音の計測部位に装着する機器を小型化・軽量化できる。 The pulse measuring device 11 shown in FIG. 3 has a structure in which the body conduction sound detecting means 12 is independent of the data processing means 13 and the display means 14, so that the user can hear arterial sounds or heart sounds such as wrists, necks, and chests. This makes it possible to reduce the size and weight of equipment attached to the measurement site.

図３に示す脈拍計測装置１１は、データ処理手段１３及び表示手段１４として、パソコン等のコンピュータ及び液晶等のディスプレイを用いることができる。 The pulse measuring device 11 shown in FIG. 3 can use a computer such as a personal computer and a display such as a liquid crystal as the data processing means 13 and the display means 14.

また、図３に示す脈拍計測装置１１は、データ処理手段１３及び表示手段１４として、スマートフォン等のコンピュータ機能を有する携帯電話端末を用いることもできる。前記データ処理手段１３及び表示手段１４としてスマートフォンを用いれば、利用者の脈拍を常時計測することが可能となる。 In addition, the pulse measuring device 11 shown in FIG. 3 can also use a mobile phone terminal having a computer function such as a smartphone as the data processing means 13 and the display means 14. If a smartphone is used as the data processing means 13 and the display means 14, the user's pulse can be constantly measured.

なお、本発明で用いる脈拍計測装置は、上記構成以外の体導音センサを利用できることはいうまでもない。 Needless to say, the pulse measuring device used in the present invention can use a body conduction sensor other than the above-described configuration.

図４（ａ）は体導音センサを手首に装着し該体導音センサにより橈骨動脈音を検知して取得した脈拍信号、図４（ｂ）は前記脈拍信号を自己相関処理して得られた自己相関データのグラフをそれぞれ示す。
図４に示すグラフから、橈骨動脈音を検知して取得した脈拍信号の波形に雑音が含まれている場合、自己相関処理することで周期信号を抽出できることが分かる。 4A is a pulse signal obtained by attaching a body conduction sensor to the wrist and detecting the radial artery sound by the body conduction sensor, and FIG. 4B is obtained by performing autocorrelation processing on the pulse signal. Each graph of autocorrelation data is shown.
From the graph shown in FIG. 4, it can be seen that when noise is included in the waveform of the pulse signal obtained by detecting the radial artery sound, the periodic signal can be extracted by performing autocorrelation processing.

図５（ａ）は体導音センサを頸部に装着し該体導音センサにより頸動脈音を検知して取得した脈拍信号、図５（ｂ）は前記脈拍信号を自己相関処理して得られた自己相関データのグラフをそれぞれ示す。
図５に示すグラフから、頸動脈音を検知して取得した脈拍信号の波形に雑音が含まれている場合でも、自己相関処理することで周期信号を抽出できることが分かる。 FIG. 5 (a) shows a pulse signal obtained by attaching a body conduction sensor to the neck and detecting carotid artery sound by the body conduction sensor, and FIG. 5 (b) is obtained by performing autocorrelation processing on the pulse signal. A graph of the obtained autocorrelation data is shown respectively.
From the graph shown in FIG. 5, it can be seen that the periodic signal can be extracted by performing the autocorrelation process even when the waveform of the pulse signal acquired by detecting the carotid artery sound includes noise.

図６（ａ）は体導音センサを胸部に装着し該体導音センサにより心音を検知して取得した脈拍信号（心拍信号）、図５（ｂ）は前記脈拍信号を自己相関処理して得られた自己相関データのグラフをそれぞれ示す。
図６に示すグラフから、心音を検知して取得した脈拍信号の波形に、前記各動脈音を検知して取得した脈拍信号に比べて大きな雑音が含まれている場合でも、自己相関処理することで周期信号を抽出できることが分かる。 FIG. 6A shows a pulse signal (heart rate signal) acquired by wearing a body conduction sensor on the chest and detecting a heart sound with the body conduction sensor, and FIG. 5B shows an autocorrelation process on the pulse signal. Graphs of the obtained autocorrelation data are shown respectively.
From the graph shown in FIG. 6, autocorrelation processing is performed even when the waveform of the pulse signal acquired by detecting the heart sound includes a larger noise than the pulse signal acquired by detecting each arterial sound. It can be seen that a periodic signal can be extracted.

図４乃至図６に示す結果から、本発明の脈拍計測装置は、体導音センサが取得する脈拍信号を自己相関処理することで、前記脈拍信号の波形に雑音が含まれる場合でも、当該脈拍信号の自己相関データから周期信号を抽出できるため、脈拍をより正確に計測することができる。   From the results shown in FIG. 4 to FIG. 6, the pulse measuring device of the present invention performs autocorrelation processing on the pulse signal acquired by the body conduction sound sensor, so that even if the waveform of the pulse signal includes noise, Since the periodic signal can be extracted from the autocorrelation data of the signal, the pulse can be measured more accurately.

以下に、自己相関関数を求める式を示す。
