<Relationship between RR interval and autonomic nerve>
Since it is known that the fluctuation pattern of the human heart rate interval is an index of the tension state of the autonomic nerve that controls the heart beat, as described above, the monitoring unit 20 has such a human heart beat. The fluctuation pattern of the interval is sensed by the heartbeat / respiration sensor 22, the state of the infant 1 is displayed by the monitor unit 26, and the surrounding environment of the infant 1 is improved by the cool air blower 28.

  Here, the relationship between the RR interval, which is the interval between the R wave and the R wave seen in the above-described ECG waveform, and the autonomic nerve of the infant 1 will be described with reference to FIG. In addition, as shown in FIG. 6, this RR interval is measured as a spectrum at a specific frequency, and the control unit 25 described above obtains the state of the infant 1 by obtaining the change in the RR interval. Operation control of the cold air machine 28 is performed.

  Thus, it is said that the RR interval (RRI) on the electrocardiogram waveform as shown in FIG. 6 is not normally kept constant, but has a property of constantly changing. The heartbeat is said to be governed by the autonomic nerve, and the sympathetic nerve that activates the body to resist the physical and mental loads of the autonomic nerve and the rest • It is antagonisticly controlled by the parasympathetic nerve that has the function of requiring a break. For this reason, it is possible to clarify the activity status of the sympathetic nerve and the parasympathetic nerve by analyzing the fluctuation of the RR interval of the heartbeat, and thereby whether the body is required to be activated or not. It is possible to clarify whether a break is required. Specifically, as shown in FIG. 5, when sympathetic nerves are increased by physical and mental loads, a spectrum in which the heart rate increases and the RR interval is shortened is detected. For this reason, if the RR interval is shortened, it can be estimated that it is in a tensioned state, and if it is longer, it can be estimated that it is in a relaxed state. That is, the stress level of the infant 1 can be calculated based on the calculated RR interval, and the control unit 25 controls the display control of the monitor unit 26 and the cold air fan 28 based on the stress level calculated in this way. Control the operation. As shown in FIG. 6, the fluctuation of the RR interval of the heartbeat is generally analyzed by frequency analysis. As a frequency characteristic, 0.04 to 0.15 Hz low frequency region (hereinafter referred to as LF), 0. Peaks occur in two places, a high frequency region (hereinafter referred to as HF) of 15 Hz or higher. Here, since the sympathetic nervous system has a characteristic of not transmitting heart rate fluctuations of 0.15 Hz or higher, when the ratio of LF and HF is calculated, the sympathetic nerve is mainly active when the LF / HF value is high. Conversely, when the LF / HF value is low, it can be estimated that the parasympathetic nerve is mainly active. In FIG. 5, CV-RR means a heart rate variability coefficient.

<Infant monitoring operation and cooler control operation by control unit>
The monitoring operation of the infant 1 and the control operation of the cold air fan 28 by the control unit 25 of the monitoring unit 20 will be described below using the block diagram of FIG. 1 and the graph of FIG.
Normally, when the infant 1 is not in the stroller 10, the monitoring unit 20 is in a standby mode. Then, when the infant 1 gets on the stroller 10, the monitoring unit 20 automatically starts with the condition that the heartbeat / respiration sensor 22 first detects body movement information of the infant 1 for a certain period of time. The monitoring mode is turned on and monitoring control is started. The fixed period here is set to 10 seconds, and the monitoring mode of the monitoring unit 20 is turned ON when the body movement information of the infant 1 is detected continuously for 10 seconds. Here, the setting can be changed to turn on the monitoring mode based on the heart rate or respiratory rate of the infant 1.

Next, when monitoring control is started, the heart rate / respiration sensor 22 measures the heart rate and respiration rate of the infant 1 and starts acquiring data every minute.
Then, as shown in FIG. 4, the control unit 25 determines whether or not the following stability conditions are satisfied for the heart rate and the respiration rate, and starts counting the confirmation time when the stability conditions are no longer satisfied. As shown in FIG. 4, the heart rate stability condition here is not less than the heart rate stability lower limit threshold a and not more than the heart rate stability upper limit threshold b, and the respiration rate stability condition is the respiration rate stability. It is not less than the lower threshold c and not more than the respiratory rate stability upper threshold d. Regarding the confirmation time, there are a heart rate confirmation time th and a respiration rate confirmation time tb for the heart rate and the respiration rate, respectively. When the state where the stability condition is not satisfied for either one of the heart rate and the respiration rate continues continuously beyond the respective confirmation times, the control unit 25 causes an abnormality in the LCD panel 26a of the monitor unit 26. By displaying a notification to the effect or transmitting a buzzer sound from the speaker 26b, the parent 2 is notified that the infant 1 is in an abnormal state. In this case, the notification unit 26 uses a notification mode when the heart rate falls below the heart rate stability lower limit threshold a, when the heart rate exceeds the heart rate stability upper limit threshold b, and the respiratory rate falls below the respiratory rate stability lower limit threshold c. When the value is lower than the upper limit threshold d of the breathing rate stability, it is possible to notify in four types of patterns. The display on the LCD panel 26a and the sound transmitted from the speaker 26b are It is set differently depending on the abnormal state.

  In addition, when counting the confirmation time, the control unit 25 considers the information on the cry of the infant 1 acquired by the microphone 23 and the body movement information acquired by the heartbeat / respiration sensor 22. That is, when there is a sound collection of a predetermined frequency at a predetermined volume or higher from the microphone 23, it is determined that the infant 1 is crying, and monitoring control is performed for a while after such sound is not observed. Do not do. Also, in the case where the body movement information of the infant 1 acquired by the heartbeat / respiration sensor 22 is intense movement that exceeds a predetermined threshold, for a while after such body movement information is no longer observed. Do not perform supervisory control. Thus, the period during which the monitoring control is not performed is provided when the infant 1 is crying or when the body movement is intense, even if the parent 2 is likely to be interested in the infant 1 and changes are occurring. This is because the state can often be quickly grasped. In addition, when the infant 1 is crying or when the body movement is intense as described above, the heart rate and the respiratory rate may be improved regardless of the health condition of the infant 1 and the wrong state monitoring is performed. This is to prevent frequent abnormality notifications from being made. Moreover, about 3 minutes are set as a short time here. In the monitoring unit 20, such a function can be canceled by changing the setting that the monitoring control is not performed for a while.

  Moreover, the control part 25 calculates the stress degree mentioned above based on the heart rate measured by the heartbeat / respiration sensor 22, and starts the operation of the cool air fan 28 when the stress degree exceeds a predetermined threshold value. Here, the operation is started at the initial set temperature of 23 degrees. The initial air volume is set based on the relationship between the temperature near the infant 1 at the start of operation and the initial set temperature, and the initial air volume is set to a larger value as the difference from the initial set temperature increases. In addition, after starting the operation of the cold air blower 28, in order to prevent a situation in which comfort is not maintained due to the infant 1 being too cold, the temperature is automatically adjusted when the stress level exceeds a predetermined threshold. Automatic adjustment control is performed in which the temperature is adjusted by the device 28a and the air volume is adjusted by the air volume adjuster 28b. Thereby, the environment around the infant 1 can be maintained in a state in which the infant 1 feels comfortable. In the automatic adjustment control here, the heart rate is measured at intervals of 5 minutes from the start of driving, the above-mentioned RR interval is calculated every 5 minutes, and the control is performed while referring to the change in the RR interval. The unit 25 changes the set temperature of the cold air fan 28 by 0.5 degrees. Here, the operation is started at the initial set temperature of 23 degrees, the operation is performed for the first 5 minutes while maintaining the set temperature at 23 degrees, and the first RR interval is obtained. When 5 minutes have elapsed, the installation temperature is raised by 0.5 degrees to 23.5 degrees, and the next 5 minutes is operated to obtain the next RR interval. When the next 5 minutes are finished, that is, when 10 minutes have elapsed from the start of operation, the control unit 25 compares the first RR interval with the next RR interval, and if the RR interval becomes a long-term change, Then, the control unit 25 determines that the set temperature has been shifted to the side where the infant 1 feels more comfortably, and increases the set temperature by 0.5 degrees and operates. On the other hand, if the RR interval is a short-term change, it is determined that the set temperature has been shifted to the side that makes the infant 1 feel uncomfortable, and the set temperature is lowered by 0.5 degrees to restore the original operation. The above setting change is repeated for the air volume in the same manner, and adjustment is performed so that the set temperature and the set air volume are optimum for the infant 1.

  In addition, when the abnormal state continues about the heart rate and the respiratory rate of the infant 1 or when it is determined by the control unit 25 that the parent 2 cannot handle the communication unit 27 of the control unit 24, Information on the heart rate and respiratory rate of the infant 1 is transmitted to the communication unit 31 of the associated medical institution 30 registered in the control unit 25 via the wireless line 40. At this time, coping method data obtained by comparing with the coping data of the patient-specific database 32 provided in the associated medical institution 30 is transmitted from the communication unit 31 of the medical institution 30 to the communication unit 27 of the control unit 24. It is automatically transmitted, or handling data determined by a doctor in charge of the medical institution 30 is transmitted. Thereby, the parent 2 who is monitoring the infant 1 can quickly cope with the abnormal state of the infant 1.

In addition, the control unit 25 automatically monitors when the body movement information of the infant 1 is not measured from the heartbeat / respiration sensor 22 for a predetermined time (for a time significantly longer than the above-described confirmation time). The monitoring mode of the unit 20 and the cooler 28 are turned off to enter the energy saving standby mode.

In general, the appearance of infants can be grasped easily by conventional monitoring devices with monitoring monitors, etc., but it is necessary to grasp the inner state in monitoring infants who are still difficult to express their intentions. Is difficult. In addition, such an internal state change may appear as an appearance on an infant's facial expression, etc., but it may be difficult to grasp the internal state from a slight change in facial expression etc. Many. For example, in a state where an infant is in a stroller and closes his eyes, it is important to judge whether he is sleeping comfortably or comfortably, or because he is uncomfortable. It is especially difficult for those who monitor parents.

  On the other hand, in the infant monitoring system in the above embodiment, since the heart rate information and the respiratory rate information are displayed on the monitor unit 26, when the infant 1 that is still difficult to express himself / herself is visually monitored. Even for internal changes that are difficult to appear, the parent 2 that performs monitoring can accurately grasp the change. Thereby, the change of the internal state of the infant 1 can be estimated. Further, even when the infant 1 is closed, it can be inferred as to whether the infant 1 is sleeping comfortably or uncomfortable, and so on. Will be able to watch over infant 1 with peace of mind.

Further, as shown in FIG. 5, the heart rate information can be used as a judgment material for estimating the arousal level, the fatigue level, the stress level, etc. of the infant 1, so that such information is acquired by the heart rate / respiration sensor. Then, the inner state of the infant 1 can be estimated by analyzing the control unit 25 or the like.
