Description

The present invention relates to an infant health management / monitoring device, and in particular, stores a body temperature trend for a predetermined time, separates a measurement unit from a main body unit, and generates an alarm when body temperature data deviates from a threshold value. Relates to the device.

There has been proposed a monitoring system that measures biological information, estimates an infant's condition, and takes an appropriate response to an infant's abnormalities (Patent Document 1: Japanese Patent Application Laid-Open No. 2004-181218). However, it is not a matter of judging how a sudden change in body temperature due to a cold, flu, infection such as RS (Respiratory Syncytial) virus, etc. differs from normal. As a system for improving this, a system that determines the urgency level of a biological signal and generates an alarm has been proposed (Patent Document 3: Japanese Patent No. 3661686). However, for body temperature, large threshold values of 40 ° C. and 34 ° C. are set and compared, and an alarm is not generated due to a trend change. There has also been proposed an electronic thermometer having a vibration actuator capable of generating sound, buzzer operation sound, or vibration that can be felt through the housing at the end of body temperature measurement (Patent Document 3: Japanese Patent Laid-Open No. Hei. 11-304597). However, since the thermometer main body vibrates, there is a problem that an infant is surprised especially at night. In addition, a sticking type electronic thermometer that includes a power supply battery and wirelessly transmits a measured body temperature value has also been proposed (Patent Document 4: Japanese Patent Laid-Open No. 63-133028).

<Acquisition of body temperature information by IC tag with built-in battery>
A nurse such as a mother first attaches the temperature measuring unit 1 equipped with the IC tag 200 to the diaper 300 in an appropriate place for body temperature measurement, for example, under the armpit or the like. 1) and is attached to or pasted at a proper position on the body so that the IC tag 200 comes into contact with the wristband. Measurement and storage for a predetermined period, for example, one month, one week, one day (24 hours) arbitrarily selected in spring, summer, autumn, and winter, and body temperature information is stored in the EEPROM 202 along with the time. The stored body temperature information is trend-stored together with the date and time in the storage unit 15 of the portable device 50 from the external transmission unit 203 via the external communication unit 12 via a signal line or wirelessly. In the infant health management / monitoring apparatus of the present invention, the IC tag 200 does not necessarily have to be provided when it is not necessary to store the normal body temperature trend.

<How to use>
As described above, the temperature measuring unit 1 including the IC tag (RFID) 100 having the temperature measuring unit on the infant P is attached to the infant P at a proper position or provided on the wristband. The temperature sensor 106 is attached (attached) under an appropriate position for measuring the body temperature, for example, under the armpit.

  The power switch 14c of the portable device 50 is turned on, and an alarm (notification means) mode is selected and set. This selection / setting is performed by the function key 14a. There are two alarm (notification means) modes for driving the alarm generator 190: vibration, melody (including sound, buzzer, etc.), alarm generation (notification) mode with all light, vibration, and melody. Mode to generate alarms (notification) with two modes: alarm, alarm mode (notification) with vibration and light, mode to generate alarms (notification) with only vibration, mode with alarm generation (notification) only with vibration, alarm only with melody There are a mode for generating (notifying) and a mode for generating (notifying) an alarm only by light. These modes may be provided, or may be provided in any combination, and these modes are selected. In addition, the hour / minute (second) at which the alarm is generated (notified) can be arbitrarily set in 10 to 60 seconds. Further, the measured body temperature threshold value (° C.) for generating (notifying) an alarm is set to 38.0 ° C. as a default value, but this setting can be performed at the input unit 14, preferably at intervals of 0.1 ° C. I am doing so.

The measurement start time setting (time setting) instruction is input using the input unit 14 and the like, and the body temperature is set by placing the portable device 50 in the bedside, futon, or bed of a nurse (mother, etc.) lying in the same futon or bed. Start measurement. The body temperature information is set at a time set in advance by the input unit 14, for example, when a temperature measurement unit including an IC tag (RFID) 100 having a temperature measurement unit is attached to the infant P and a measurement start instruction is input. For example, an electromagnetic wave having a predetermined frequency, for example, 13.56 MHz, is sent from the IC tag reading unit 13 to the IC tag 100 after a predetermined interval, for example, every 10 minutes (5 to 5 minutes). (In this case, the transmission / reception distance is about 3 cm to 10 cm), and the 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 as necessary (can be set by the input unit 14 so as not to store the trend). This body temperature information is compared with a set alarm generation threshold (° C.). This threshold is, for example, 38.0 ° C. This threshold value can be set and input arbitrarily by the nurse (mother or the like) using the input unit 14 based on the body temperature trend information (normal heat (° C.)) for the predetermined period described above, and can be changed.

If the measured body temperature information is determined to be abnormal (including abnormalities during measurement), a vibration melody (including sound and buzzer), light, etc. are notified. At this time, if the LED of the display unit 11 is caused to emit light at the same time, the body temperature at the time of alarm occurrence can be read and confirmed even in the dark such as at night. The body temperature measurement is continued by resetting the input unit 14, but the body temperature measurement can be terminated by pressing the power switch 14c.

FIG. 3 is different from the above-described embodiment in another embodiment in that an alarm generation unit 190 is provided separately from the main body, and the alarm generation unit 190 is driven by wire or wireless via a signal line. In this case, a nurse (mother or the like) does not need to lie in the same futon or bed, but can lie in another futon or bed and place the alarm generation unit 190 on the futon or bed.

It is a figure which shows the Example of this invention. It is a block diagram concerning the example of the present invention. It is a block diagram which shows the other Example of this invention.
