Description

  The present invention relates to a technique for measuring cardiac potentials of a pregnant woman and a fetus.

  There are various devices for acquiring biological information of pregnant women and fetuses in order to check the health status of the pregnant woman and fetus and the state before giving birth. In particular, the state of the heart of the pregnant woman and the fetus is one of the important indexes, and the electrocardiogram of the pregnant woman and the fetus is measured by attaching a measuring device to the pregnant woman immediately before giving birth. A typical apparatus is one in which electrodes are attached to the abdomen of a pregnant woman who is resting in a bed, as in Patent Document 5 and Patent Document 4, and the electrocardiogram of the fetus is measured. Further, as a device for a pregnant woman to more easily know the state of the heart of the fetus, a device for recording the heart sound of the fetus using a microphone as in Patent Document 3 has been proposed.

  In addition, devices for observing fetal conditions in addition to heart conditions have been proposed (see Patent Documents 1 and 2). For example, Patent Document 2 describes a physical condition management device for constantly monitoring the physical condition of a pregnant woman and the state of a fetus. In the physical condition management device of Patent Document 2, a body temperature sensor, a pulse and blood pressure sensor, and a microphone are attached to the inside of an abdominal band worn by a pregnant woman on the abdomen, and biological information is collected.

  Currently, opportunities for pregnant women to know the health status of the fetus are limited at the time of screening, and there is an increasing need for pregnant women to know the health status of the fetus in real time with their own hands. In order to obtain awareness, it is considered that a device for measuring the electrocardiogram of the fetus on a daily basis for a long time is suitable for the pregnant woman.

  However, the technique described in Patent Document 5 has a problem that it cannot be used for the purpose of checking the state of the heart of the fetus on a daily basis because the pregnant woman needs to be at rest. Furthermore, since it is necessary to attach the electrode to an accurate position, knowledge of an expert is required, so that there is a problem that an amateur cannot use it for daily measurement. Further, the technique of Patent Document 4 can measure fetal electrocardiograms even if the electrode mounting position is not accurate to some extent by adopting a technique of extracting fetal electrocardiograms by analyzing potentials obtained at multiple points. However, there is a problem that it is not possible to use it for checking the condition of the fetus heart on a daily basis because it is necessary to make the pregnant woman rest and there is a trouble of attaching and detaching many electrodes.

  Moreover, in the technique described in Patent Document 2 or 3, the heart sound of the fetus can be confirmed on a daily basis. However, the heart sound is insufficient as the index for knowing the state of the fetus with less information than the electrocardiogram. There was a problem. Specifically, heart sounds can detect abnormal rhythms such as arrhythmia, but changes or abnormalities in the electrocardiogram waveform, not rhythm, such as hypokalemia or hyperkalemia. Cannot cope with symptoms detected by. Furthermore, the method for recording heart sounds described in Patent Document 2 has a problem that noise generated due to clothing misalignment or the like is mixed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

  FIG. 1 is a block diagram showing a configuration example of a potential acquisition abdominal band according to an embodiment of the present invention. FIG. 2 is a diagram illustrating an example of how the abdominal band is used according to the embodiment. A plurality of potential acquisition electrodes 11 (hereinafter simply referred to as electrodes 11) are attached to the potential acquisition abdominal band 1 (hereinafter referred to as abdominal band 1) so as to contact the abdominal skin of the pregnant woman. In order to obtain potential data for extracting electrocardiogram data, the plurality of electrodes 11 contact the skin and detect the potential. The potential detected by the electrode 11 is sent to the potential data transmitter 12. The potential data transmission unit 12 stores the potential transmitted from the plurality of electrodes 11 as potential data, or transmits the potential data wirelessly.

  The electrode 11 of FIG. 1 is preferably made of, for example, a conductive fiber, and is preferably a type of electrode 11 that has a good touch and is in close contact with the skin. The potential data transmission unit 12 in FIG. 2 is not a means for transmitting a potential but is a potential recording device for recording potential data, for example, an SD card. The electrode 11 contacts the abdominal skin of the pregnant woman, acquires the potential of the pregnant woman's abdomen, and sends it to the potential recording device (potential data transmission unit 12). The potential recording device records on the potential data SD card sent from the plurality of electrodes 11. After recording the potential data, for example, an SD card on which one day of potential data is recorded is connected to a pregnant woman / fetal electrocardiograph 20 which will be described later. Each ECG data is separated and extracted.

  FIG. 3 is a diagram illustrating different examples of the usage status of the abdominal band according to the embodiment. In the example of FIG. 3, the potential data transmission unit 12 transmits potential data by wireless communication. The potential data transmission unit 12 uses, for example, BlueTooth (registered trademark) or a wireless LAN. The potential receiving unit 21 receives the potential data transmitted from the potential data transmitting unit 12. The potential receiving unit 21 uses, for example, BlueTooth (registered trademark) or a wireless LAN, similarly to the potential data transmitting unit 12.

  The potential receiving unit 21 is connected to the potential recording unit 50 and sends the received potential data to the potential recording unit 50. The potential recording unit 50 stores potential data. The potential recording unit 50 records potential data on a storage medium such as an SD card, for example. Alternatively, the potential recording unit 50 is built in the pregnant woman / fetal electrocardiograph 20 and stores potential data in a nonvolatile memory such as a magnetic disk device or a solid-state storage device.

  When recording potential data on a storage medium such as an SD card, the SD card on which the potential data is recorded is connected to the pregnant woman / fetal electrocardiograph 20 as in the example of FIG. 20 separates and extracts the electrocardiogram data of each pregnant woman and fetus. When the potential recording unit 50 is built in the pregnant woman / fetal electrocardiograph 20, the pregnant woman / fetus electrocardiograph 20 separates and extracts the electrocardiogram data of the pregnant woman and the fetus from the stored potential data.

  The abdominal band 1 may have the configuration shown in FIG. 2 or FIG. In the following embodiments, description will be made mainly assuming the configuration of FIG. When the potential data is transmitted to the pregnant / fetal electrocardiograph 20 by wireless or the like, the electrocardiogram data can be analyzed in real time.

(Embodiment 1)
FIG. 4 is a block diagram showing a configuration example of the pregnant woman / fetal electrocardiograph according to Embodiment 1 of the present invention. The pregnant woman / fetal electrocardiograph 2 according to the first embodiment includes an abdominal band 1 and a pregnant woman / fetus electrocardiograph 20. The abdominal band 1 is the abdominal band 1 shown in FIG. 1 or FIG. As described with reference to FIG. 1, the abdominal band 1 transmits the potentials sent from the plurality of electrodes 11 to the pregnant woman / fetal electrocardiograph 20 as potential data.

  The pregnant woman / fetus electrocardiogram measurement unit 20 includes a potential receiving unit 21, a pregnant woman / fetus electrocardiogram separation unit 22, a pregnant woman / fetus electrocardiogram analysis unit 23, and an information presentation unit 24. As described with reference to FIG. 3, the potential receiving unit 21 receives potential data transmitted from the abdominal band 1. Here, the potential receiving unit 21 sends the received potential data to the pregnant / fetal electrocardiogram separation unit 22.

  The pregnant woman / fetus electrocardiogram separation unit 22 separates and extracts the electrocardiogram data of the pregnant woman and the fetus from the potential data obtained by mixing a plurality of potentials. The pregnant woman / fetus electrocardiogram separation unit 22 sends the electrocardiogram data of each pregnant woman and fetus to the pregnant woman / fetus electrocardiogram analysis unit 23. The pregnant woman / fetus electrocardiogram analysis unit 23 analyzes the electrocardiogram data of the pregnant woman and the fetus, performs analysis such as extraction of an abnormal state, and sends the analysis result to the information presentation unit 24. The information presentation unit 24 presents the electrocardiogram data and the analysis result of each pregnant woman and fetus sent from the pregnant woman / fetus electrocardiogram analysis unit 23.

  Each part of the pregnant woman / fetus electrocardiograph 2 operates in detail as follows. When the pregnant woman wears the abdominal band 1, the electrode 11 contacts the abdominal skin of the pregnant woman, acquires the potential of the pregnant woman's abdomen, and sends it to the potential data transmission unit 12. The potential data transmission unit 12 transmits the potential transmitted from the plurality of electrodes 11 to the potential reception unit 21 by wireless or the like.

  The potential receiver 21 sends the plurality of potentials sent from the potential data transmitter 12 to the pregnant woman / fetus electrocardiogram separator 22. The pregnant woman / fetus electrocardiogram separation unit 22 separates and extracts the pregnant woman electrocardiogram and fetus electrocardiogram from the potential data obtained by mixing a plurality of potentials, and the pregnant woman / fetus electrocardiogram data is sent to the pregnant woman / fetus electrocardiogram analysis unit 23. send.

  In order to separate the electrocardiogram data of the pregnant woman and the fetus by the pregnant woman / fetal electrocardiogram separation unit 22, for example, a technique such as ICA (Independent Component Analysis) can be cited. ICA is a calculation method that separates a multivariate signal into multiple independent components, and changes the potential of the abdominal muscles of the pregnant woman, the electrocardiogram of the pregnant woman, and the electrocardiogram of the fetus to the independent potentials. It can be used as a method for separation.

  The pregnant woman / fetal electrocardiogram separation unit 22 separates potential independent components using, for example, ICA, and extracts a signal in which the peak interval of the potential is within a common heart rate range. Then, the extracted signal having the largest magnitude is extracted as the pregnant electrocardiogram and the second largest signal as the fetal electrocardiogram.

  The pregnant woman / fetus electrocardiogram analysis unit 23 analyzes the electrocardiogram data of the pregnant woman and the fetus sent from the pregnant woman / fetus electrocardiogram separation unit 22, performs abnormality extraction, and sends the data to the information presentation unit 24. Examples of the analysis performed by the pregnant woman / fetal electrocardiogram analysis unit 23 include, for example, “data such as pregnant woman electrocardiogram and fetal electrocardiogram are not extracted”, “the heartbeat or waveform of the pregnant woman electrocardiogram is abnormal”, “fetal heart "The heartbeat or waveform of electricity is abnormal". For example, the abnormal analysis is performed by determining in advance the normal ranges of the pregnant woman and the fetus of the characteristics of the electrocardiogram data and checking whether the characteristics of the sent electrocardiogram data fall within the range. The characteristics of the electrocardiographic data can be, for example, a period, a difference between the maximum value and the minimum value, a maximum value of the change rate, a ratio of the frequency component included to the fundamental frequency (period), and the like. The characteristics used for electrocardiographic data analysis can be determined from a medical point of view.

  The information presentation unit 24 presents the electrocardiogram data and analysis results of the pregnant woman and the fetus sent from the pregnant woman / fetus electrocardiogram analysis unit 23 with images, alert sounds, and the like.

  FIG. 5 is a diagram illustrating an example of the pregnant / fetal electrocardiograph according to the first embodiment. The example of FIG. 5 is a configuration in which the abdominal band 1 shown in FIG. 3 and a data analysis computer 30 corresponding to the pregnant woman / fetal electrocardiograph measurement unit 20 communicate with each other wirelessly. For example, the potential receiver 21 is a small communication device that is built in the data analysis computer 30 and receives data using the BlueTooth (registered trademark) communication function.

  In the example shown in FIG. 5, the pregnant woman / fetus electrocardiogram separation unit 22 and the pregnant woman / fetus electrocardiogram analysis unit 23 are realized by a program operating on the data analysis computer 30. The information presentation unit 24 is a program that operates on the data analysis computer 30 to display the pregnant / fetal electrocardiogram and heart rate, and abnormalities of the pregnant / fetal electrocardiogram on a display device connected to the data analysis computer 30. is there.

  FIG. 6 is a flowchart showing an example of the electrocardiogram data analysis operation of the first embodiment. First, the electrode 11 contacts the abdominal skin of the pregnant woman, acquires the potential of the pregnant woman's abdomen, and sends it to the potential data transmission unit 12 (step S10). Next, the potential data transmission unit 12 transmits the potentials transmitted from the plurality of electrodes 11 as potential data to the pregnant woman / fetus electrocardiogram measurement unit 20 by wireless communication, and the potential reception unit 21 receives the potential data ( Step S11).

  Next, the pregnant / fetal electrocardiogram separation unit 22 separates the potential data by, for example, the ICA method, and further extracts the electrocardiogram data of the pregnant woman and the fetus from the separated potential data by the peak interval analysis and the waveform size analysis. (Step S12). The pregnant woman / fetus electrocardiogram analysis unit 23 analyzes the electrocardiogram data of each pregnant woman and fetus, for example, by analyzing the presence / absence of electrocardiogram data that seems to be a pregnant woman / fetus electrocardiogram and whether the heart rate is an abnormal value. Then, the electrocardiogram abnormalities of the pregnant woman and the fetus are determined (step S13).

  The information presenting unit 24 presents, for example, an image of the display device or an alert sound and information on whether or not the pregnant woman / fetus electrocardiogram and the heart rate and the analysis result of the pregnant woman / fetus electrocardiogram are abnormal (step S14). . The pregnant woman / fetal electrocardiograph 2 returns to step S10 and repeats from the acquisition of potential data until it is stopped.

  As described above, according to the pregnant / fetal electrocardiograph 2 according to the first embodiment, the pregnant woman wears the abdominal band 1 including the electrode 11 and the potential data transmission unit 12, so that the heart of each pregnant woman and fetus can be obtained. Electric data can be measured. Pregnant women can measure the fetal electrocardiogram while sending their daily lives without being constrained by the measuring device, and can save the trouble of attaching and detaching a large number of electrodes 11 when performing daily measurements.

  In the pregnant / fetal electrocardiograph 2, the fetal electrocardiogram separation means separates electrocardiographic data of the pregnant woman and the fetus from potential data obtained by mixing a plurality of potentials obtained by a large number of electrodes 11 using a technique such as ICA. Therefore, the fetal electrocardiographic data can be correctly measured even when the measurement is performed only by an amateur. Furthermore, fetal electrocardiograms can be separated and extracted from noise generated by actions in daily life.

  In the pregnant woman / fetal electrocardiograph 2 according to the first embodiment, since a technique for separating potentials obtained by a large number of electrodes 11 is used, the pregnant woman can be dynamically changed as long as the position of the abdominal band 1 is roughly. ECG and fetal ECG are separated. As a result, the pregnant woman's electrocardiogram and the fetal electrocardiogram can be correctly found even when measurement is performed only by an amateur, and further, the pregnant woman's electrocardiogram and the fetal electrocardiogram can be separated from noises caused by actions in daily life.

(Embodiment 2)
FIG. 7 is a block diagram showing a configuration example of the pregnant / fetal electrocardiograph according to Embodiment 2 of the present invention. In the second embodiment, the acceleration of the pregnant woman is detected, and the operation of the pregnant woman is determined from the acceleration. Then, the state of the pregnant woman and the fetus is analyzed from the determined operation and the electrocardiographic data separated and extracted. In the second embodiment, in addition to the configuration of the first embodiment, the abdominal band 1 includes an acceleration sensor 13 and an acceleration data transmission unit 14. The pregnant woman / fetal electrocardiogram measurement unit 20 includes an acceleration data reception unit 25 and an operation determination unit 26. Other configurations are the same as those of the first embodiment. However, the pregnant / fetal electrocardiogram analysis unit 23 analyzes the states of the pregnant woman and the fetus in consideration of the determined operation.

  The acceleration sensor 13 shown in FIG. 7 detects the acceleration of the body of the pregnant woman wearing the abdominal band 1. The acceleration sensor 13 sends the detected acceleration to the acceleration data transmission unit 14 as acceleration data. The acceleration data transmission unit 14 transmits the acceleration data to the acceleration data reception unit 25 of the pregnant woman / fetus electrocardiogram measurement unit 20.

  The acceleration data transmission unit 14 may share a transmitter with the potential data transmission unit 12. The acceleration data transmission unit 14 and the potential data transmission unit 12 generate data to be transmitted in their respective data formats.

  The acceleration data receiving unit 25 of the pregnant woman / fetus electrocardiogram measuring unit 20 receives the acceleration data transmitted from the acceleration data transmitting unit 14 and sends it to the motion determining unit 26. The motion determining unit 26 determines the size of the pregnant woman's motion from the acceleration data of the pregnant woman body sent from the acceleration data receiving unit 25, and sends the determined motion information to the pregnant / fetal electrocardiogram analyzing unit 23.

  Also in the second embodiment, the potential data transmitter 12 transmits potential data, and the potential receiver 21 receives potential data. Then, the pregnant woman / fetal electrocardiogram separation unit 22 separates and extracts the electrocardiogram data of the pregnant woman and the fetus from the potential data.

The pregnant woman / fetal electrocardiogram analysis unit 23 sends the analysis result to the information presentation unit 24.

  In addition to the analysis described in the first embodiment, the pregnant woman / fetus electrocardiogram analysis unit 23 determines whether the electrocardiogram data of the pregnant woman and the fetus can be trusted, for example, according to the size of the operation of the pregnant woman. For example, when the motion of the pregnant woman's body exceeds a predetermined range, it is determined that the state is that “the motion of the pregnant woman's body is large, and thus the extracted electrocardiogram data of the pregnant woman and the fetus are not reliable”.

  FIG. 8 is a diagram illustrating an example of the pregnant / fetal electrocardiograph according to the second embodiment. In the example of FIG. 8, it is shown that the abdominal band 1 shown in FIG. 5 includes an acceleration sensor 13 and an acceleration data transmission unit 14.

When the acceleration sensor 13 and the acceleration data transmission unit 14 are separate bodies, only the electrode 11 and the potential data transmission unit 12 can be attached.

  FIG. 9 is a flowchart showing an example of the electrocardiogram data analysis operation of the second embodiment. The electrode 11 contacts the abdominal skin of the pregnant woman, acquires the potential of the pregnant woman's abdomen, and sends it to the potential data transmission unit 12 (step S20). Moreover, the acceleration sensor 13 acquires the acceleration of the pregnant woman body, and sends it to the acceleration data transmission part 14 (step S21). In FIG. 9, it is described that acceleration data acquisition is performed following acquisition of potential data. However, since potential data and acceleration data are acquired independently of each other, either may be performed first or may be performed simultaneously.

  The potential data transmission unit 12 transmits the potential transmitted from the plurality of electrodes 11 to the potential reception unit 21 by wireless or the like, and the potential reception unit 21 receives the potential data. Further, the acceleration data transmission unit 14 transmits the acceleration data of the pregnant woman body transmitted from the acceleration sensor 13 to the acceleration data reception unit 25 by wireless or the like, and the acceleration data reception unit 25 receives the acceleration data (step S22). .
