Respiratory information and heartbeat information of a living body are particularly useful information for discriminating a sign of an asthma attack or a mild asthma attack. It is preferable that the biological information acquisition unit 10 acquires the respiratory information or the heartbeat information of the living body, and it is more preferable to acquire both the respiratory information and the heartbeat information of the living body. The biological information acquisition unit 10 may be controlled to continuously acquire biological information, or may be controlled to acquire biological information intermittently.

The respiratory information and heartbeat information may be as long as they are related to asthma symptoms, and the respiratory information and heartbeat information are preferably information related to the time cycle of breathing and heartbeat.

Examples of the biometric information acquirer constituting the biometric information acquisition unit 10 include electrodes, elastic capacitors, and the like. These can be used alone or in combination. When these are used in combination, they may be provided independently or integrally. The electrode may be any as long as it can detect electrical information, and preferably includes, for example, a first insulating layer and a conductive layer provided on the first insulating layer. A second insulating layer may be provided on the conductive layer, in which case at least a part of the conductive layer is not covered with the second insulating layer and is exposed to the skin of the living body. It is preferable that they come into contact with each other. The electrode may be non-stretchable or stretchable, but it is preferable that the electrode has elasticity so that it can follow the movement of the living body to some extent. Further, it is preferable that the electrodes are fixed to the skin side surface of the clothing fabric. Examples of such elastic electrodes include the electrodes described in JP-A-2020-100903.

Is preferable. Further, the elastic capacitor is preferably fixed to the cloth of clothing. Examples of the stretchable capacitor include the capacitor type element described in Japanese Patent Application Laid-Open No. 2019-072048.

Examples of the living body for which the biological information is acquired from the biological information acquisition unit 10 include animals such as dogs, cats, horses, cows, sheep, and monkeys, and humans. According to the asthma symptom management system 1, since the symptom of the living body can be objectively grasped, it can be suitably used for children, animals and the like.

The specific information generation unit 30 has an average value of breathing frequency, an average value of heartbeat frequency, an average value of breathing interval, and a heartbeat interval calculated based on the biological information acquired from the biological information acquisition unit 10. The specific information S1 is generated when at least one of the average values satisfies at least one of the following equations. That is, in the specific information generation unit 30, when the average value of the breathing frequency satisfies the following equation (1) and the average value of the heartbeat frequency satisfies the following equation (1), the average value of the breathing intervals is The specific information S1 is generated when the following equation (2) is satisfied, when the average value of the heartbeat intervals satisfies the following equation (2), or when two or more of these are satisfied.
A1 + B1 ≤ A2 ≤ A1 + B2 ... (1)
[In the formula, A1 is the average value of the frequency of respiration and / or heartbeat in the first predetermined period, and A2 is the second starting point after 1 minute or more from the end point of the first predetermined period. It is the mean value of the frequency of respiration and / or heartbeat in a predetermined period, B1 is a positive constant, and B2 is a positive constant of B1 or more. However, when A1 is the average value of the frequency of respiration, A2 is the average value of the frequency of respiration, and when A1 is the average value of the frequency of heartbeat, A2 is the average value of the frequency of heartbeat. ]
C1-B4 ≤ C2 ≤ C1-B3 ... (2)
[In the formula, C1 is the average value of the breathing and / or heartbeat intervals in the first predetermined period, and C2 is the second starting point starting from a time point one minute or more after the end point of the first predetermined period. It is the mean value of the interval between breathing and / or heartbeat in a predetermined period, B3 is a positive constant, and B4 is a positive constant of B3 or more. However, when C1 is the mean value of the breathing interval, C2 is the mean value of the breathing interval, and when C1 is the mean value of the heartbeat interval, C2 is the mean value of the heartbeat interval. ]

Equations (1) and (2) compare the current biological information of the living body with the biological information one minute or more ago to determine whether or not the living body has a sign of an asthma attack or a mild asthma attack. It is an index. Since the biometric information of a sign of asthma attack or a mild attack of asthma fluctuates more slowly than that of a severe attack, there is little difference in fluctuation even when comparing the biometric information of adjacent predetermined periods, and it is difficult to discriminate the sign of the attack. On the other hand, it is possible to easily determine the sign of a seizure or the like by comparing with the biological information one minute or more ago. Therefore, the time interval between the end point of the first predetermined period and the start point of the second predetermined period is preferably 2 minutes or more, more preferably 5 minutes or more. On the other hand, the upper limit of the time interval is not particularly limited, but may be 72 hours or less, or may be 1 hour or less.

When the specific information generation unit 30 generates the specific information S1, it is possible to notify the living body or a third party that a sign of an asthma attack or a mild asthma attack has occurred. When the living body starts abdominal breathing, deep breathing, etc. triggered by this notification, it is possible to avoid exacerbation of the symptom. Further, the specific information generation unit 30 may be controlled to end the generation of the specific information S1 once the symptom has subsided.

It is preferable that the specific information generation unit 30 is controlled so as to generate the specific information S1 when the above equation (1) or equation (2) is satisfied. Further, in the specific information generation unit 30, either the average value of the breathing frequency and the average value of the heartbeat frequency satisfy the equation (1), or the average value of the breathing interval and the average value of the heartbeat interval are the equations (2), respectively. ) Satisfying the above conditions, it is more preferable that the specific information S1 is controlled to be generated. When both the average value of the frequency of respiration and the average value of the frequency of heartbeat are used in calculating the formula (1), it is preferable to independently apply the average value to the formula (1) for calculation. In this case, each B1 may have a different value, and each B2 may have a different value. Similarly, when both the average value of the breathing interval and the average value of the heartbeat interval are used in calculating the equation (2), it is preferable to independently apply the equation (2) to the calculation. In this case, each B3 may have a different value, and each B4 may have a different value.

The asthma symptom management system 1 is controlled to generate specific information S1 when A2 is A1 + B2 or less, and is controlled not to generate specific information S1 when A2 is more than A1 + B2. Is preferable. Further, when C2 is C1-B4 or more, it is controlled to generate specific information S1, and when C2 is less than C1-B4, it is controlled not to generate specific information S1. preferable. This makes it possible to easily detect a sign of asthma and a mild attack of asthma without detecting a severe attack of asthma in a living body.

The average value of the frequency of respiration is, for example, the average of the time intervals between the peaks of the waveform related to the change in impedance in a predetermined period, and the time in the predetermined period divided by the average time interval to obtain the respiratory rate in the predetermined period ( It can be calculated by calculating the number of breaths (times) and dividing the respiratory rate (times) by the time (minutes, etc.) of a predetermined period. In addition, the frequency of breathing (times / minute, etc.) per n predetermined times (for example, 1 minute) within a predetermined period is obtained, and the average value of the frequency of n breaths (times / minute, etc.) is used as the frequency of breathing. It may be an average value. However, n is an integer of 1 or more.

Similarly, the average value of the frequency of heartbeats is determined by, for example, obtaining the average of the R wave and the time interval (RRI) of the electric wave of the electric wave in a predetermined period and dividing the time of the predetermined period by the average value of the above RRI. It can be obtained by obtaining the number of heartbeats in a period and dividing the number of heartbeats by the time (minutes, etc.) in a predetermined period. In addition, the frequency of heartbeats (beats / minute, etc.) per n predetermined time (for example, 1 minute) within a predetermined period is obtained, and the average value of the frequencies of n heartbeats (times / minute, etc.) is used as the frequency of heartbeats. It may be an average value. However, n is an integer of 1 or more.

The average value of the breathing interval can be obtained, for example, by calculating the average of the time intervals between the peaks of the waveform related to the change in impedance in a predetermined period. Further, the average value of the breathing intervals in n predetermined times (for example, 1 minute) within a predetermined period may be obtained, and the average of n such average values may be obtained and used as the average value of the breathing frequency. However, n is a number of 1 or more.

Similarly, the average value of the heartbeat interval can be obtained, for example, by calculating the average of the R wave and the time interval (RRI) of the R wave of the electric wave in a predetermined period. Further, the average value of the heartbeat intervals in n predetermined times (for example, 1 minute) within a predetermined period may be obtained, and the average value of n RRIs may be obtained as the average value of the heartbeat frequencies. However, n is a number of 1 or more.

When each constant is within these numerical ranges, it is possible to easily avoid fluctuations within the physiological fluctuations within the normal range of biological information and detection of severe seizures and the like.

The respiration frequency and respiration interval can be calculated by the calculation unit 24 described later based on, for example, a change in impedance between electrodes, a change in capacitance due to expansion and contraction of an elastic capacitor, and the like. The heartbeat frequency and the heartbeat interval can be calculated by the calculation unit 24 described later, for example, based on the R wave and the R wave interval (RRI) of the electrocardiographic waveform obtained from the electrodes.

The specific information S1 may be any one that notifies a sign of an asthma attack in a living body or a mild asthma attack, and preferably notifies that the time cycle of the biological information has been shortened. Specifically, it is more preferable that the specific information S1 notifies that the temporal cycle such as RRI, respiratory rate (cpm), and heart rate (bpm) has become shorter.

The specific information S1 is generated by the specific information generation unit 30, and examples of the specific information S1 include perceptible information such as electricity, sound, vibration, light, and video.

If the living body can recognize a sign of an asthma attack or a mild asthma attack by specific information S1, for example, video, the living body should consciously start abdominal breathing, deep breathing, etc. to avoid exacerbation of symptoms. Can be done. For example, when the specific information S1 is a video, "increased respiratory rate", "increased heart rate", "predictive occurrence of asthma attack", etc. are displayed, and a sign of asthma attack occurs in a living body or the like. Should be displayed to notify. Further, the specific information S1 preferably induces respiration with an appropriate rhythm. For example, the specific information S1 displays notifying that a sign of an asthma attack has occurred in the living body, and appropriately displays "inhale", "exhale", etc. so as to guide breathing with an appropriate rhythm. It may be done in a cycle.

Further, the specific information S1 may induce the living body to abdominal breathing or the like regardless of the consciousness of the living body. For example, when the specific information S1 is electric, the living body may be guided to abdominal breathing by flowing it to the abdominal muscle through the electrode of the electric generator and periodically contracting the abdominal muscle of the living body.

The first predetermined period is preferably set when the living body is in a resting state.
