Description

The present invention relates to an apparatus for monitoring and managing the health of an infant by measuring biological data such as heart rate, respiration rate, body movement, body temperature, etc. in sleeping or lying down on an infant.

In recent years, due to the nuclear family and the declining birthrate, the burden on mothers for raising infants has become extremely large. Even if an infant has a sudden fever such as influenza at home, the information may be delayed and become serious. In addition, SIDS (sudden infants) that infants under the age of 2 years old who had been completely healthy until then without any special abnormalities or illness, suddenly died without any warning during sleep, rather than accidents or suffocation. Some are called death syndromes.

Under such circumstances, as a method of continuously grasping the health condition without giving a burden without being burdened, that is, without restraint, an air mat is laid under the subject's body and based on the pressure change applied to the air mat. A technique for measuring a subject's heart rate, respiratory rate, number of snoring, number of times to lie down, etc. has been proposed (Patent Document 1). In addition, a home dock system that checks information such as blood pressure, pulse, and body temperature every day while staying at home and displays a trend is also proposed (Patent Document 2).

However, it is necessary to manually input and transmit data such as blood pressure, pulse, body temperature and the like each time measurement is performed. Further, a bearing abnormality inspection system has been proposed using an IC tag integrated with a temperature sensor (Patent Document 3). In the case of afflicted patients, particularly infants, even if there is a sudden fever due to an infection such as influenza at night, it may be delayed and too late. However, an apparatus for managing / monitoring body temperature data of a living body without giving a physical and mental burden to a subject (an elderly person, a patient being treated, an infant) or a caregiver has not yet been proposed.

The stored body temperature information is stored in the storage units 44 and 15 by, for example, contacting the external transmission unit 38 of the terminal 5 or the external communication unit 12 of the portable terminal 50.

<Specific configuration of monitoring system>
The infant P wears a diaper (pants) 300 on the air mat 2 for measuring biological data. The diaper 300 includes a trunk opening 201 provided with an elastic member, a leg opening 202 provided with an elastic member, and an absorption member (not shown), and has an IC tag (RFID) (second temperature measuring unit) having a temperature measuring part. ) 100 is provided inside, at an appropriate position away from the absorbent member.

A measurement unit (for example, every 1 to 5 minutes) is measured for a predetermined time (for example, 24 hours), and a reading unit (not shown) in which the body temperature data stored in the EEPROM 202 is stored in the external transmission unit 38 is brought into contact with the external communication unit 203. And stored in the storage unit 44. When used in a hospital or the like, it is stored together with ID data (name, date of birth, sex, blood type, hospital room number, etc.) of the infant P. The diaper 300 is not limited to a pants shape, but may have other shapes. Alternatively, the diaper may be made of cloth, made reusable and a diaper cover may be used, and the diaper may be provided at an appropriate place inside that is not wet by urine. The IC tag 100 having the temperature measuring unit may be surrounded by an enclosing member having a hook-and-loop fastener and the like so as to be detachable.

The terminal device 5 includes a pressure sensor that detects a change in pressure, and processes the detection signal to a management site / medical site (not shown) via a dedicated line such as a LAN or an information communication network such as the Internet (not shown). A control monitoring device for transmission is provided.

The IC tag 100 having a temperature measuring unit may be inserted into the ear, such as an earphone, or may be affixed to an arbitrary location on the body surface to acquire body temperature information at a plurality of locations. In this case, an anti-co-region type IC tag is used that enables reading of temperature information at the same time even when there are a plurality of infants P in a hospital room or the like. A server (data processing device) may be installed at the management site / medical site, and measurement data of biological information may be collected, aggregated, analyzed, etc. in association with the ID of the infant P.

  In FIG. 2, reference numeral 40 denotes a control unit (CPU) that executes a predetermined processing flow based on a computer-readable program stored in the ROM 42, the RAM 43, etc., predetermined conditions, and the like. Reference numeral 36 denotes a display unit, and 44 denotes a storage unit that stores biological information such as detected body temperature, heartbeat, and respiration. Reference numeral 20 denotes a fine differential pressure sensor, and reference numeral 21 denotes an absolute pressure sensor. The internal pressure of the air mat 2 is input to the fine differential pressure sensor 20 and the absolute pressure sensor 21 via the air tube 4. Since vibration caused by the body of the infant P is transmitted to the air mat 2, the internal pressure of the air mat 2 changes. The fine differential pressure sensor 20 detects the pressure fluctuation, and the absolute pressure sensor 21 detects the absolute pressure of the internal pressure of the air mat 2. The absolute pressure sensor 21 is provided to detect whether the infant P is on the air mat 2.

As the fine differential pressure sensor 20, for example, a condenser microphone type differential pressure gauge that detects a differential pressure by detecting a change in capacitance between a pressure-receiving surface that receives a change in pressure and a counter electrode is used. The condenser microphone type differential pressure gauge can detect minute pressure fluctuations in the air mat 2.

The detection signal of the fine differential pressure sensor 20 is given to a gain control unit 31 that constitutes the monitoring control device 30. The gain control unit 31 adjusts the level of the detection signal of the fine differential pressure sensor 20 to a signal level within a predetermined range. Since the strength of vibration transmitted to the air mat 2 varies depending on the posture of the infant P, the intensity (level) of the output signal of the fine differential pressure sensor 20 varies. The gain control unit 31 adjusts the gain so that a signal level that varies depending on the posture becomes a signal of a predetermined level, and outputs the signal to the heartbeat filter 32 and the respiratory filter 33. Further, the gain value of the gain control unit 31 is added to the posture determination unit 36. By applying the output signal of the differential pressure sensor 20 converted to a predetermined level by the gain control unit 31 to the heart rate filter 32 and the respiratory filter 33, the infant P such as a heart rate signal and a respiratory signal is output from the heart rate filter 32 and the respiratory filter 33. Biological data can be obtained. The biological data of the infant P obtained from the heartbeat filter 32 and the breathing filter 33 is converted into a digital signal by the A / D converter 35 and input to the data processor 37. Further, temperature information is intermittently received by the IC tag reading unit 34 (for example, every 5 to 30 minutes) from the IC tag 100 with a temperature sensor (see FIG. 1) attached to the inside of the diaper 200 attached to the subject P. Read on. The IC tag reading unit 34 transmits an electromagnetic wave having a predetermined frequency of 13.56 MHz, and the signal is received by the IC tag 100 with a temperature sensor via an antenna, and temperature (body temperature) information (in this embodiment, by the temperature sensor 106). The body temperature information in the vicinity of the abdomen of the subject P is read from the IC tag 100 with a temperature sensor. The IC tag 100 can identify and read temperature information at the same time by using an anti-collusion type. The data processing unit 37 performs various arithmetic processes on the input biological data and monitors the state of the infant P. The various types of calculation processing of the biological data include pattern comparison with the normal biological data of the subject P. The data processing unit 37 performs arithmetic processing when the absolute pressure sensor 21 detects that the infant P is on the air mat 2.

Further, the gain value of the gain control unit 31 is added to the posture determination unit 36. Since the level of the detection signal of the fine differential pressure sensor 20 that detects the internal pressure of the air mat 2 differs depending on the posture of the infant P, the gain control unit 31 performs gain adjustment.

The biometric data identifies the heart rate, the respiratory rate, and the like based on the characteristics of signals captured by the differential pressure sensor (relative pressure sensor) 20 and the absolute pressure sensor 21. For example, the heart rate and the respiration rate are separated into frequencies in the normal range through the filters 32 and 33. After conversion into a digital signal by the A / D conversion unit 35, the data processing unit 37 performs fast Fourier transform to obtain a fundamental frequency that becomes a peak spectrum, and extracts each of them.

<Biological information processing flow>
The biometric information processing flow will be described with reference to FIG.
Measurement is started under one condition that the infant P is on the air mat 2 (recumbent, supine state) (the measurement may be started by inputting a start instruction). A pressure signal is acquired (detected) by the differential pressure sensor (relative pressure sensor) 20 and the absolute pressure sensor 21 at a set predetermined interval, for example, every 10 to 60 minutes (step S1). Based on the characteristics of the acquired pressure signal, the heart rate, respiration rate, etc. are identified, and the heart rate, respiration rate, etc. are calculated (step S2). One pressure detection time is about 2 to 5 minutes. In addition, body temperature information is transmitted from the IC tag reading unit 34 to the IC tag 100 mounted on the infant P at a predetermined frequency, for example, every 10 to 60 minutes, with an electromagnetic wave having a predetermined frequency of 13.56 MHz. Transmission (transmission / reception distance is about 10 cm to 1 m), and body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read. The body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read (step S3). This biological information is stored in the storage unit 44 (step S4). This biological information is compared with a threshold value. For example, in the case of body temperature, the upper limit value is 37.5 ° C., and the lower limit value is 35.5 ° C. For example, the upper limit value is 120 beats / minute, the lower limit value is 30 beats / minute, and the respiration rate is, for example, the upper limit value is 90 / minute and the lower limit value is 10 / minute. Moreover, the upper limit of the temperature of the outer surface of the ice pillow 120 is set to 36.5 ° C., for example. If at least one of these pieces of biological information is determined to be abnormal, an alarm is generated (step S6) and notified to the doctor in charge at the management site / medical site. In addition, you may make it alert | report on a mobile telephone etc. of a doctor in charge. After confirming the condition of the infant P determined to be abnormal, it is reset (step S7) as necessary. If it is not necessary, the monitoring (measurement) is terminated. If there is no abnormality, the process returns to step S1 as necessary, and the measurement of the biological information is repeated until a measurement end instruction is input. The biometric information measured and stored in the storage unit 44 obtains an average value, a maximum value, a minimum value, and a maximum value, and stores the data together with the ID of the infant P in the storage unit 44 and a server (not shown). . The biological information such as heart rate, respiration rate, and body temperature stored in the storage unit 44 is trend-displayed on the display unit 36 and the display unit 11 as shown in FIG. In the display unit 36 and the display unit 11, the heart rate, the respiratory rate, and the body temperature are simultaneously displayed every hour (60 minutes), but one or any combination of these may be displayed. Further, by inputting medication data such as an antipyretic as memo information together with the date and time by the input unit 45 or the input unit 14, it can be displayed together with the trend display of the biological information on the display unit 36 and the display unit 11. The same display can be performed on the display part (not shown) of the management site / medical site. As another condition for determining to generate an alarm, when the body temperature value exceeds one threshold, for example, 37.5 ° C., and the body temperature change rate (° C./minute) exceeds a predetermined value, for example, 1 ° C./60 minutes. An alarm can be generated when the value exceeds. For example, an alarm can be generated when 39 ° C. is exceeded for a predetermined time, for example, about 3 hours. In this case, when the body temperature value exceeds one threshold, for example, 37.5 ° C., the measurement interval may be controlled to be shorter than the initial predetermined interval.

The analysis time (predetermined time) based on pressure detection can be set to an arbitrary time, not 2 to 5 minutes. The analysis time may be a time convenient for data analysis of one bedtime, and can be set within a predetermined bedtime instead of one bedtime. The optimum conditions are set according to the system size and analysis speed. For example, the data processing unit 37 determines the health status of the infant P based on the following criteria.

Next, we will explain the abnormal monitoring during sleep and emergency calls. The data processing unit 37 of the terminal device 5 analyzes the biological data for a predetermined time (2 to 5 minutes) to calculate the heart rate, the respiration rate, and the like, and from the temperature information from the IC tag, these are abnormal. When the specified value range is exceeded, a temperature abnormality, heart rate abnormality, and respiratory rate abnormality are displayed on the display device, and an emergency call is reported to the management PC. The data processing unit 37 displays a heart rate abnormality and respiratory rate abnormality on the display device and sounds a buzzer. When the body movement continues for a certain period of time or more, the data processing unit recognizes a seizure and similarly performs display and a buzzer response, and notifies the management PC of the management site / medical site via the information communication network. In response to this, a medical staff such as a doctor at the management site / medical site feeds back a coping method through an information communication network, telephone, FAX, or the like. Note that the respiration detection may be performed by the airflow detection method or the respiration sound detection method, not by the vibration method described above, and the respiration rate may be calculated or performed by a pulse oximeter.

If the biometric information is acquired and displayed by the mobile terminal 50 in addition to the terminal device 5, the burden on the caregiver can be reduced. In FIG. 1, as with the terminal device 5, the mobile terminal 50 includes a display unit 11, an input unit 14, an external communication unit 12 that can communicate with the terminal device 5 and an information communication network such as the Internet, a storage unit 15, and a computer-readable device. ROM 16 and RAM 17 in which various programs and predetermined conditions are stored, and a control unit (CPU) 10 for processing the entire system. The body temperature information of the infant P is directly read from the IC tag 100, the IC tag reading unit 13 is provided for directly reading the body temperature information of the IC tag 200 with a built-in battery, and the light, vibrator, sound and the like are provided. If the notification unit 19 is provided, the burden on the mother or the like can be reduced.

<Normal health management based on body temperature information>
After putting the diaper 300 provided with the IC tag 100 on the infant P, the measurement start instruction is given by the input unit 14, the input unit 45, or the measurement start time setting (time setting) instruction is given by the input unit 14, the input unit 45, etc. The body temperature measurement is started by inputting. The body temperature information is based on a time condition set and input in advance by the input unit 14 and the input unit 45, for example, a point in time when a predetermined temperature rise is confirmed, for example, an IC tag (second temperature measuring unit) after 5 minutes, for example. An IC tag reader 13 transmits an electromagnetic wave of 13.56 MHz to 100 (the transmission / reception distance is about 10 cm to 1 m), and body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read. The measured body temperature information is stored in the storage unit 15. This body temperature information is compared with a threshold value. For example, in the case of body temperature, the upper limit value is 37.5 ° C., and the lower limit value is 35.5 ° C. If it is determined that the body temperature information is abnormal (including abnormalities during measurement), an alarm is generated. When the measurement is completed, a buzzer, vibrator, light, voice, etc. are notified. When there is an abnormality (for example, basal body temperature at the time of fever), “fever” is displayed on the display unit 11, a note to that effect is input by the input unit 14, and the storage unit 15 stores it. If abnormal, reset as necessary (step S6), return to step S1, and measure the body temperature again. If there is no abnormality, the measured body temperature is stored, and the body temperature measurement is terminated.

Information such as body temperature and memo input stored in the storage unit 15 is displayed on the display unit 11 for a predetermined period, for example, 30 days. If it can be displayed together with a variorhythm calculation / display function (described later), the physical condition of the day can be easily confirmed (see FIG. 8). Such information, together with the ID of the subject P, is encrypted and transmitted over the Internet, a dedicated LAN, etc. to the server of a health-related service provider or a medical site such as the attending physician, and if necessary, such as comments from the attending physician You can get advice.

<Other usage patterns>

In this case, the temperature measuring unit 1, the IC tag 100, and the IC tag reading unit 34 need not be provided. When the body temperature is measured for a predetermined time (about 1 to 5 minutes) after being attached to an appropriate position on the body of the infant P (underarm, diaper, etc.), the body temperature information is stored along with the time in the EEPROM 202 of the battery built-in IC tag 200. The stored body temperature information is stored in the storage unit 15 from the external transmission unit 203 through the external communication unit 18 by setting the battery built-in IC tag 200 at a predetermined position of the terminal device 5 or by a connection terminal (reading start switch or the like). May be provided to instruct reading start). The maximum value of the stored body temperature information is displayed on the display unit 11 as the measured body temperature.

The portable terminal 50 and the battery built-in IC tag 200 can function as an electronic thermometer. In this case as well, the wireless IC tag reader 13 need not be provided. When the body temperature is measured for a predetermined time (about 1 to 5 minutes) after being attached to an appropriate position on the body of the infant P (underarm, diaper, etc.), the body temperature information is stored along with the time in the EEPROM 202 of the battery built-in IC tag 200.

Etc. may be provided to instruct reading start). The maximum value of the stored body temperature information is displayed on the display unit 11 as the measured body temperature.

<Other functions and operations>
Other functions and operations will be described in detail below based on FIG.
(1) Time setting When a battery is inserted into the portable terminal 50, necessary data including the current year / month / day / hour and its sum value are read from the EEPROM 16 which is a nonvolatile memory (step S600). While the battery is being inserted, a signal is sent from the clock (timer) 14 to the arithmetic processing unit 10 once every hour and every 00 minutes in a process (not shown). When received, the current year, month, date, and time are written in the EEPROM 16 (step S601).

  Next, the read sum value of the current year, month, date, and hour is calculated, and it is confirmed whether it is equal to the read sum value (step S602). If they are equal, the process proceeds to the SLEEP state. If not equal, it is determined that the read value is invalid, and the error flag FLAGerr is set (= 1) (step S603).

Next, the system waits in the SLEEP state until the power switch is pressed, that is, until the power is turned on (steps S604 and S605).

When the power is turned on by the power switch, FLAGerr is confirmed, and if it is a predetermined condition, for example, other than 1, the operation proceeds to a temperature detecting operation (step S608). If FLAGerr is 1, the process proceeds to date / time input processing (step S607). Here, a screen prompting the user to input the date / time is displayed, and the user inputs the current year / month / date / time according to the screen. As another method, regardless of the value of FLAGerr, a method of always shifting to the date / time input process when the power is turned on for the first time after inserting the battery is also conceivable. In this case, the sum value and sum check functions are unnecessary. Further, by providing the radio timepiece, the sum value and sum check functions become unnecessary. In addition, it is more convenient to provide a radio clock when inputting medication memos to prevent medication status confirmation and mistakes. By doing this, the user can quickly and easily set the year, month, day, hour, and minute, and even if the current year, month, day, and hour of the EEPROM is damaged, the user can quickly set the correct date. . Thus, the set current time is displayed on the display unit 11 by the calendar function based on the clock function and the calendar. That is, while AM and PM indicating AM and PM are displayed, the current time is displayed, and the date is updated every time the time count by the clock function elapses 24 hours, and this date is displayed on the display unit 11 by the calendar function. Is done. In addition, “year” may be displayed on the display unit 11.
