Description

  The present invention relates to a biological state determination device for determining whether or not a defibrillator is to be used for a patient, and a defibrillator equipped with the same. The present invention also relates to a living body monitoring apparatus for detecting an abnormal breathing state of a monitored person, and a living body monitoring system including the living body monitoring apparatus.

  In recent years, defibrillators are spreading to public facilities and private facilities. An automated external defibrillator (AED), one of the defibrillators, applies electrical shock to the heart of patients with ventricular fibrillation, a fatal arrhythmia. The heart beat is restored from the fibrillation state to the normal state. As a general method of using the AED, the caregiver first checks the patient's consciousness and the presence or absence of the pulse, and if there is no consciousness and pulse, removes the patient's clothes and exposes the chest, and then the pair of electrodes of the AED. Apply the pad to the chest. The AED analyzes an electrocardiogram waveform of the patient using the electrode pad, and applies an electric shock to the patient through the electrode pad when it is determined that the patient has ventricular fibrillation.

  In Patent Document 1 below, a specially shaped cover removed from the defibrillator case is disposed between the patient's neck and shoulders and the floor, so that the patient's jaw is lifted by the cover. An external defibrillator is disclosed that is in a posture and thereby can secure the patient's airway.

  In addition, a disease called sleep apnea syndrome (SAS) that becomes an apnea state or a hypopnea state during sleep is known.

Japanese Patent No. 4272058

  As described above, in a general method of using a defibrillator, a caregiver first checks the patient's consciousness and the presence or absence of a pulse. However, it is not easy for a general caregiver who is not engaged in daily relief work to accurately determine the presence or absence of a patient's pulse. It is often difficult for a general caregiver to calmly judge the presence or absence of a patient's pulse in an emergency situation in which a person who has lost consciousness falls down in front of him. Moreover, since it is necessary to expose a chest part in order to stick an electrode pad, it requires special caution especially when a patient is an adult woman. For example, although the patient's pulse is normal, there is a possibility that the chest is exposed due to an erroneous determination that there is no pulse. Conversely, the caregiver may hesitate to expose the chest because the patient is an adult woman, in which case the defibrillator is in need of defibrillation. Inappropriate situations may occur where it is not used.

  In addition, sleep apnea syndrome has a weak subjective symptom and is difficult for the patient to notice. Thus, for example, when a train driver suffers from severe sleep apnea syndrome, if a strong drowsiness due to lack of sleep associated with sleep apnea syndrome occurs during driving, normal driving The operation cannot be performed, and in the worst case, an accident may occur.

  FIG. 5 is a diagram illustrating a first usage example of the biological situation determination device 1. A person 100 who has lost his consciousness and falls down is laid on the floor 30. After the caregiver presses the start button of the operation unit 15, the caregiver uses the adhesive tape or the like of the sticking unit 16 to stick the biological state determination device 1 on the chest of the person 100 (on the clothes). Alternatively, when the person 100 is wearing clothes having a pocket in the chest, the living body condition determining apparatus 1 is inserted into the pocket. The radio wave 50 transmitted from the transmission unit 11 is reflected by the ceiling surface of the ceiling 31, and the reception unit 12 receives the reflected wave 51. It should be noted that the pressing of the start button and the arrangement of the biological state determination device 1 on the chest of the person 100 may be in the reverse order of the above example.

  FIG. 6 is a diagram illustrating a second usage example of the biological situation determination device 1. A person 100 who has fallen out of consciousness outdoors is laid on the ground 32. After the caregiver presses the start button of the operation unit 15, the caregiver sticks the biological condition determination device 1 on the chest (clothes) of the person 100, or the biological condition determination device in the pocket of the chest, as described above. Insert 1 The caregiver arranges a support 40 (not shown in FIG. 1) provided in the defibrillator 2 so as to cover the chest of the person 100. It should be noted that the pressing of the start button and the arrangement of the biological state determination device 1 on the chest of the person 100 may be in the reverse order of the above example.

  FIG. 7 is a perspective view schematically showing the support 40. The support body 40 includes four support legs 42 and a top plate 41 supported by these support legs 42. The supporting leg 42 is accommodated when not in use by a known folding mechanism or expansion / contraction mechanism. In order to arrange the support 40 in a short time, a mechanism in which all the support legs 42 appear by a one-touch operation by a caregiver is used.

  Referring to FIG. 6, radio wave 50 transmitted from transmitting unit 11 is reflected by the bottom surface of top plate 41, and receiving unit 12 receives the reflected wave 51.

  FIG. 8 is a diagram illustrating a third usage example of the biological situation determination device 1. A person 100 who has fallen out of consciousness outdoors is laid on the ground 32. In the example illustrated in FIG. 8, the biological state determination device 1 is disposed on the bottom surface of the top plate 41. In the case of this example, the biological state determination device 1 when not in use is stored in a state of being fixed in advance to the bottom surface of the top plate 41. Alternatively, the caregiver may affix the biological state determination device 1 taken out from the recess 8 of the case lid 3 </ b> B to the bottom surface of the top plate 41. The caregiver arranges the support body 40 so as to cover the chest of the person 100. Thereby, the biological condition determination apparatus 1 will be located substantially in front of the chest of the person 100 (including the front and the front). Thereafter, when the caregiver presses the start button of the operation unit 15, the radio wave 50 is transmitted from the transmission unit 11 toward the chest of the person 100. The transmitted radio wave 50 is reflected by the chest of the person 100, and the receiving unit 12 receives the reflected wave 51.

  In addition, although the usage method outdoors was demonstrated in FIG.6, 8, it can be used indoors by the same method.

  9-13 is a figure for demonstrating the process in the detection part 25 and the determination part 26 (refer FIG. 4). First, the detection unit 25 measures the time variation of the distance from the biological state determination device 1 to the reflection surface based on the radio wave 50 transmitted by the transmission unit 11 and the reflected wave 51 received by the reception unit 12. This distance measurement is periodically performed at minute time intervals (for example, 100 msec intervals).

  In the example illustrated in FIG. 5, the biological state determination device 1 is disposed on the chest of the person 100 and the reflection surface is the ceiling surface of the ceiling 31, so that the detection unit 25 extends from the chest of the person 100 to the ceiling 31. Measure the time variation of the distance to the ceiling.

  In the example shown in FIG. 6, the biological state determination device 1 is disposed on the chest of the person 100 and the reflection surface is the bottom surface of the top board 41, so The time variation of the distance to the bottom surface of the plate 41 is measured.

  Further, in the example shown in FIG. 8, the biological state determination device 1 is disposed on the bottom surface of the top plate 41 and the reflection surface is the chest of a person. Detect the time variation of the distance to the chest.

  Specifically, the transmission unit 11 transmits a radio wave 50 having a predetermined frequency toward the reflection surface, and the reception unit 12 receives a reflected wave 51 that is the radio wave 50 reflected by the reflection surface. When the chest of the person 100 moves up and down with breathing or heartbeat, the distance from the biological state determination device 1 to the reflecting surface changes according to the up-and-down movement. Therefore, the reflected wave 51 is reflected by the Doppler effect. The frequency is shifted from the frequency of the radio wave 50. Therefore, based on the difference between the frequency of the transmitted radio wave 50 and the frequency of the received reflected wave 51, the distance from the biological state determination device 1 to the reflecting surface can be measured. As a ranging method using a radio wave in the microwave region, a two-frequency CW (Continuous Wave) method using two transmission radio waves having different frequencies, FM-CW (Frequency) that continuously changes the frequency of the transmission radio wave by frequency modulation. There are a modulated-continuous wave (DDS) method and a DDS method using a transmission wave of a desired waveform generated by digital data synthesis using a DDS (Direct Digital Synthesizer) circuit, but any method can be adopted. FIG. 9 shows an example of the time variation of the distance from the biological state determination device 1 to the reflection surface measured by the detection unit 25. The waveform shown in this example includes a low-frequency component accompanying breathing of the person 100 and a high-frequency component accompanying heartbeat of the person 100.

  Next, the detection unit 25 performs frequency analysis by FFT (Fast Fourier Transform) for the range of the latest predetermined period (for example, 30 seconds) in the waveform representing the time variation of the distance from the biological state determination device 1 to the reflecting surface. By doing so, the waveform representing the time variation of the distance is converted into a waveform representing the signal intensity for each frequency. 10 to 13 show various waveforms obtained by FFT.

  FIG. 10 shows a waveform when both respiration and heartbeat are normal. A frequency band R1 (for example, 0.3 to 0.8 Hz) corresponding to a general breathing cycle of a normal human being is set, and a peak at which the signal intensity is equal to or higher than a predetermined threshold Th1 in the frequency band R1. If it appears, the determination unit 26 determines that the breathing state of the person 100 is normal. The threshold value Th1 is stored in the storage unit 21 illustrated in FIG. Further, based on the peak frequency, the respiration rate of the person 100 per predetermined period (for example, 1 minute) can be calculated. For example, when the peak frequency is 0.5 Hz, the respiration rate of the person 100 is 60 × 0.5 = 30 (times / min). Then, the determination unit 26 determines whether the respiration status of the person 100 is normal based on a comparison result between the respiration rate of the person 100 and a threshold value indicating the upper and lower limits of the range of the normal respiration rate of a normal human. It may be determined whether or not.

  In addition, a frequency band R2 (for example, 1.0 to 2.0 Hz) corresponding to a general heartbeat cycle of a normal human is set, and the signal intensity is equal to or higher than a predetermined threshold Th2 in the frequency band R2. If a peak appears, the determination unit 26 determines that the heartbeat status of the person 100 is normal. The threshold value Th2 is stored in the storage unit 21 illustrated in FIG. Further, based on the peak frequency, the heart rate of the person 100 per predetermined period (for example, one minute) can be calculated. For example, when the peak frequency is 1.25 Hz, the heart rate of the person 100 is 60 × 1.25 = 75 (times / minute). Then, the determination unit 26 determines whether the heart rate of the person 100 is normal based on the comparison result between the heart rate of the person 100 and a threshold value indicating the upper and lower limits of the normal heart rate range of a normal human. It may be determined whether or not.

  FIG. 11 shows waveforms when breathing is normal and heartbeat is abnormal. The determination unit 26 determines that the breathing state of the person 100 is normal when a peak where the signal intensity is equal to or higher than the threshold Th1 appears in the frequency band R1. Moreover, the determination part 26 determines with the heartbeat condition of the person 100 being abnormal because the peak from which signal strength becomes more than threshold value Th2 does not appear in frequency band R2. Note that a frequency band R3 (for example, 7.0 to 10.0 Hz) corresponding to a general heartbeat cycle of a human in a state where ventricular fibrillation is occurring may be set, and the signal intensity is within this frequency band R3. When a peak that is equal to or greater than the predetermined threshold Th3 appears, the determination unit 26 can determine that ventricular fibrillation has occurred in the person 100. The threshold value Th3 is stored in the storage unit 21 shown in FIG.

  FIG. 12 shows a waveform when breathing is abnormal and heart rate is normal. The determination unit 26 determines that the breathing state of the person 100 is abnormal because the peak at which the signal intensity is equal to or higher than the threshold Th1 does not appear in the frequency band R1. Further, when the peak at which the signal intensity is equal to or higher than the threshold Th2 appears in the frequency band R2, the determination unit 26 determines that the heartbeat status of the person 100 is normal.

  FIG. 13 shows a waveform when both breathing and heartbeat are abnormal. The determination unit 26 determines that the breathing state of the person 100 is abnormal because the peak at which the signal intensity is equal to or higher than the threshold Th1 does not appear in the frequency band R1. Moreover, the determination part 26 determines with the heartbeat condition of the person 100 being abnormal because the peak from which signal strength becomes more than threshold value Th2 does not appear in frequency band R2. As in FIG. 11, the determination unit 26 can also determine that ventricular fibrillation has occurred in the person 100 when a peak whose signal intensity is equal to or higher than the threshold Th <b> 3 appears in the frequency band R <b> 3. .

  The threshold values Th1 to Th3 may be the same value or different values. Appropriate values are set by experiment or simulation.

  The determination unit 26 determines that the use of the defibrillator 2 is necessary when the heartbeat status of the person 100 is abnormal. Therefore, it is determined that the use of the defibrillator 2 is not necessary for the examples shown in FIGS. 10 and 12, and it is determined that the use of the defibrillator 2 is necessary for the examples shown in FIGS. The Rukoto. The result of determination by the determination unit 26 (that is, whether or not the defibrillator 2 is necessary) is displayed on the display unit 13 of the biological state determination device 1 and is output from the audio output unit 14 as audio. Thereby, the caregiver can know whether or not it is necessary to use the defibrillator 2 for the person 100.

  As another example of the determination method, the determination unit 26 uses the defibrillator 2 when a peak whose signal intensity is equal to or higher than the threshold Th3 appears in the frequency band R3 regardless of the breathing state of the person 100. May be determined to be necessary. Also in this case, it is determined that the use of the defibrillator 2 is not necessary for the examples shown in FIGS. 10 and 12, and the use of the defibrillator 2 is not used for the examples shown in FIGS. It will be determined that it is necessary.

  As yet another example of the determination method, the determination unit 26 determines that it is necessary to use the defibrillator 2 for the person 100 except when both the breathing state and the heartbeat state of the person 100 are normal. Also good. In other words, when at least one of the respiratory condition and the heartbeat condition is abnormal, it may be determined that the use of the defibrillator 2 is necessary. In this case, it is determined that the use of the defibrillator 2 is not necessary for the example shown in FIG. 10, and it is determined that the use of the defibrillator 2 is necessary for the examples shown in FIGS. The Rukoto. As a general method of using AED, the caregiver confirms the presence or absence of the pulse and breathing of an unconscious patient, and when there is no pulse or breathing, the patient's chest is exposed and an electrode pad is applied. There is also a case. However, it is not easy for a general caregiver who is not engaged in daily relief work to accurately determine the patient's pulse and breathing. In addition, when the patient is performing gasping breathing (deadline breathing), there is a possibility that gasping breathing is erroneously determined as normal breathing. Accordingly, the determination unit 26 determines whether or not the respiration status and the heart rate status of the person 100 are normal, and when at least one of the respiration status and the heart rate status is abnormal, the use of the defibrillator 2 is necessary. Is displayed on the display unit 13, the caregiver can know whether or not it is necessary to use the defibrillator 2 for the person 100.

And the detection part 25 detects the heartbeat condition (and respiratory condition) of the person 100 based on the reflected wave 51 which the receiving part 12 received, and the determination part 26 is the heartbeat condition (and respiratory condition) by the detection part 25. Based on the detection result, whether or not it is necessary to use the defibrillator 2 for the person 100 is determined. Accordingly, the determination unit 26 can determine that the use of the defibrillator 2 for the person 100 is necessary when the heartbeat condition (or breathing condition) of the person 100 is abnormal. As a result, it is possible to accurately determine whether or not it is necessary to use the defibrillator 2 for the person 100 as compared with the case where the decision is made by the caregiver's judgment.

A time fluctuation is measured, and a heartbeat situation (and a breathing situation) is detected based on a measurement result of the time fluctuation of the distance (that is, a measurement result of the distance within a predetermined period). When the chest moves up and down with the heartbeat (and breathing) of the person 100, the distance from the biological state determination device 1 to the chest changes. Therefore, based on the measurement result of the time variation of the distance, it is possible to accurately detect the heartbeat situation (and breathing situation) of the person 100.

Next, the detection unit 25 performs frequency analysis by FFT on the range of the latest predetermined period (for example, 30 seconds) in the waveform (for example, FIG. 9) representing the time variation of the distance from the biological monitoring device 9 to the reflection plate 72. By doing so, the waveform representing the time variation of the distance is converted into a waveform representing the signal intensity for each frequency.

Further, an automatic voice message or alarm sound for calling the person 100 is output from the voice output unit 81 as a voice.

  When the person 100 suffers from severe sleep apnea syndrome, strong sleepiness due to lack of sleep associated with sleep apnea syndrome may occur during driving. When the person 100 falls into a sleep state during driving and sleep apnea syndrome develops in that state, the person 100 during driving temporarily enters an apnea or hypopnea state. The living body monitoring device 9 detects the apnea state or the hypopnea state, and outputs an automatic voice message or the like from the voice output unit 81 of the control device 71, whereby the person 100 can be awakened from the sleep state. In addition, not only when the person 100 suffers from sleep apnea syndrome but also when an abnormal breathing state occurs in the person 100 due to sudden or chronic illness or disease, the living body monitoring device 9 The abnormal breathing state can be detected.

  The control center 86 that has received the data D1 from the control device 71 makes a wireless call to the person 100 who is the driver of the train. When there is no response from the person 100 or when there is a response from the person 100 that informs the occurrence of an emergency, a control signal D2 for decelerating or stopping the corresponding train is sent to the control device 71 of the corresponding train. Send to. Control device 71 which received control signal D2 controls a train by train control part 85 so that a train may be decelerated or stopped.

The determination unit 26 determines that the person 100 is in a normal breathing state. In addition, when the frequency band R1L corresponding to the general breathing cycle of a low-breathing state is set, and the peak whose signal intensity is equal to or higher than the threshold Th1 appears in the frequency band R1L, the determination unit 26 Determines that the person 100 is in a hypopnea state. In addition, when the frequency band R1H corresponding to the general breathing cycle of a hyperbreathing person is set, and the peak where the signal intensity is equal to or higher than the threshold Th1 appears in the frequency band R1H, the determination unit 26 Determines that the person 100 is in hyperventilation. In addition, in any of the frequency bands R1N, R1L, and R1H, when no peak whose signal intensity is greater than or equal to the threshold Th1 appears, the determination unit 26 determines that the person 100 is in an apnea state. The threshold value Th1 is stored in the storage unit 21 illustrated in FIG. Further, based on the peak frequency, the respiration rate of the person 100 per predetermined period (for example, 1 minute) can be calculated.

The determination unit 26 determines that the person 100 is in a normal heartbeat state. In addition, when the frequency band R2L and the frequency band R2H are set on the low frequency side and the high frequency side of the frequency band R2N, respectively, and a peak appears in the frequency bands R2L and R2H where the signal intensity is equal to or higher than the threshold Th2. The determination unit 26 determines that the person 100 is in an abnormal heartbeat state. In addition, in the frequency bands R2N, R2L, and R2H, when no peak where the signal intensity is equal to or higher than the threshold Th2 does not appear, the determination unit 26 determines that the person 100 is in a heartbeat stop state. Note that the heart rate of the person 100 per predetermined period (for example, 1 minute) can also be calculated based on the peak frequency. Then, the determination unit 26 may determine whether the person 100 is in a normal heartbeat state, an abnormal heartbeat state, or a heartbeat stop state based on the calculated heart rate.

  In the example shown in FIGS. 17 and 18, when the determination unit 26 determines that an abnormal heartbeat state or a heartbeat stop state has occurred in the person 100, data D1 indicating the occurrence of the abnormal heartbeat state or the heartbeat stop state is obtained. The data is transmitted from the communication unit 60 to the communication unit 83. The data D1 received by the communication unit 83 is input from the communication unit 83 to the communication unit 84 via the processing unit 80, and then transmitted from the communication unit 84 to the control center 86 together with the train and driver identification information. In addition, log information including the time when the control device 71 receives the data D1 from the biological monitoring device 9 is stored in the storage unit 82. Further, an automatic voice message or alarm sound for calling the person 100 is output from the voice output unit 81 as a voice.

  20 and 21, when the determination unit 26 determines that an abnormal heartbeat state or a heartbeat stop state has occurred in the person 100, data D4 indicating the occurrence of the abnormal heartbeat state or the heartbeat stop state is obtained. The data is transmitted from the communication unit 60 to the communication unit 96. Then, log information including the time when the management device 92 received the data D4 from the biological monitoring device 9 is stored in the storage unit 95.

When the chest moves up and down as the person 100 breathes, the distance from the chest to the reflector 72 changes. Therefore, it is possible to accurately detect the breathing state of the person 100 based on the measurement result of the time variation of the distance.

  Moreover, according to the biological monitoring device 9 according to the present embodiment, as illustrated in FIGS. 20 and 21, the transmission unit 11 is directed from the substantially front of the chest of the person 100 who is the person being monitored toward the chest of the person 100. Then, the radio wave 50 is transmitted, and the receiving unit 51 receives the reflected wave 51.

Therefore, by installing the living body monitoring device 9 above the bed 90 or the like used by the person 100, the living body monitoring device 9 can detect sleep apnea syndrome that is difficult for the patient himself to notice. In addition, when an abnormal breathing state occurs in the person 100, the living body monitoring device 9 detects it to take an appropriate measure such as an automatic call to the person 100 or an automatic report to the monitoring site. It becomes possible.

  Further, according to the living body monitoring apparatus 9 according to the present embodiment, as shown in FIGS. 20 and 21, the detection unit 25 determines the distance from the living body monitoring apparatus 9 to the chest of the person 100 based on the reflected wave 51. A time variation is measured, and a respiratory state is detected based on a measurement result of the time variation of the distance (that is, a measurement result of the distance within a predetermined period). When the chest moves up and down as the person 100 breathes, the distance from the biological monitoring device 9 to the chest of the person 100 changes. Therefore, it is possible to accurately detect the breathing state of the person 100 based on the measurement result of the time variation of the distance.

  Further, according to the living body monitoring system according to the present embodiment, the control device 71 and the management device 92 (management device) are data D1 and D4 related to the occurrence state of the abnormal breathing state in the person 100 obtained by the living body monitoring device 9. And performs predetermined management based on the data D1 and D4. Therefore, the management device can manage the occurrence of sleep apnea syndrome and the automatic notification to the monitoring site.

  Further, according to the living body monitoring system according to the present embodiment, as shown in FIG. 18, the train control unit 85 (moving body control unit) indicates that an abnormal breathing state has occurred in the person 100 during the operation of the train. When the data D1 is received, control for decelerating or stopping the train is performed based on the control signal D2 received from the control center 86. This makes it possible to prevent accidents from occurring.

  Further, according to the living body monitoring system according to the present embodiment, as shown in FIG. 21, the management device 92 indicates that an apnea state has occurred in the sleeping person 100 for a predetermined time (for example, 10 seconds) or more. By receiving the data D4, the state of occurrence of sleep apnea syndrome in the person 100 is managed. Thus, the sleep apnea syndrome that is difficult for the patient to notice can be appropriately managed by the management device 92.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of claims for patent, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims for patent. For example, in each of the above embodiments, the living state of a person is detected based on the result of frequency analysis of a time-varying waveform of distance, but the living state may be detected by an algorithm different from this.
