Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a divisional application of U.S. patent
application Ser. No. 15/316,986, filed Dec. 7, 2016, which is a
U.S. National Application that claims the priority to Japanese PCT
Application No. PCT/JP2016/058925 filed Mar. 22, 2016 both of which
are hereby incorporated by reference in their entireties.
TECHNICAL FIELD
[0002] The present invention relates to a basal body temperature
measuring system and a basal body temperature measuring device, and
more particularly to a device and system for measuring a basal body
temperature in attachment to a body of a user for a sleeping
period.
BACKGROUND ART
[0003] A human basal body temperature represents a body temperature
measured in a resting state in which a factor of a change in a body
temperature caused by activity is eliminated and only a minimum
energy required for life support is consumed. In the case of women,
the basal body temperature is closely related to an ovulation
cycle. For this reason, the basal body temperature is utilized for
various purposes, for example, reference of a woman who desires
pregnancy or nonpregnancy, analysis of the cause of irregular
menstruation or observation of progress thereof, and the like.
Recently, the basal body temperature is utilized for a beauty,
regulation of a health condition or the like in some cases.
[0004] Usually, the basal body temperature of a woman is changed
periodically between approximately 0.3 to 0.5 degree except for the
case of a sickness or heavy stress. By measuring the basal body
temperature every day to know a rhythm (a change in a body
temperature), it is possible to grasp a condition of a body such as
presence of ovulation, a period of menstruation or a period likely
to get pregnant.
[0005] It is necessary to accurately capture a fine change in a
value. For this reason, the basal body temperature is usually
measured in a body resting state. As a specific measuring method,
it is recommended to perform measurement in a state in which a user
is lying down in bed when a body has not been moved and an inner
part of the body is taking a rest immediately after waking with
enough sleeping.
[0006] Conventionally, there is proposed the technique for starting
various sensors in a timing five minutes before a set time of an
alarm clock (a standard time required for measuring a body
temperature by a temperature sensor), deciding by these sensors
whether the user is trying to measure a basal body temperature, and
giving warning if there is a possibility that the measurement might
be forgot (for example, see Patent Document 1).
[0007] According to the technique described in the Patent Document
1, the user can be promoted to measure the basal body temperature
without forgetting it immediately after waking. Referring to the
technique described in the Patent Document 1, however, the user
measures the basal body temperature after the user is forcibly
waken through an alarm clock or receives the warning from a device.
For this reason, the measurement cannot be performed in a resting
state.
[0008] On the other hand, there is also proposed the technique for
going to bed with a body temperature measuring device attached to a
housing pocket in underwear and measuring a basal body temperature
and recording the basal body temperature in a memory during
sleeping (for example, see Patent Document 2). The Patent Document
2 also describes that the sleep onset of a user is confirmed by the
acceleration sensor and the measurement of a body temperature is
then started by the temperature measuring element. According to the
technique described in the Patent Document 2, it is possible to
measure a basal body temperature in a resting state during
sleeping.

[0010] Patent Document 2: Japanese Laid-Open Patent Publication No.

DISCLOSURE OF THE INVENTION
[0011] Referring to the technique described in the Patent Document
2, however, the body temperature is continuously measured from
sleep onset to wake-up. Therefore, it is impossible to specify
which time zone for a body temperature is grasped to be suitable
for a basal body temperature during that time. The body temperature
is changed by a delicate movement such as turn-over. For this
reason, the body temperature to be measured from the sleep onset to
the wake fluctuates. In the case of the Patent Document 2, there is
a problem in that it is impossible to specify which of the
fluctuating body temperatures is grasped to be the basal body
temperature.
[0012] The present invention has been made to solve the problems
and has an object to enable accurate measurement of a basal body
temperature in a resting state.
[0013] In order to attain the object, in the present invention,
body temperature information to be measured by a temperature sensor
for a sleeping period is recorded in a storage medium in
association with movement information to be detected by a movement
detecting sensor for the same sleeping period, and the movement
information recorded in the storage medium is then analyzed to
detect a wake timing of a user and body temperature information
measured immediately before the wake timing is specified as a basal
body temperature.
[0014] According to the present invention having the structure
described above, the body temperature of the user can be measured
in a resting state during sleeping and be recorded in the storage
medium. In addition, the body temperature recorded immediately
before waking can be specified as a basal body temperature.
Therefore, it is possible to obtain an accurate basal body
temperature measured in the resting state immediately before the
waking.

BEST MODE FOR CARRYING OUT THE INVENTION
First Embodiment
[0021] A first embodiment of the present invention will be
described below with reference to the drawings. FIG. 1 is a block
diagram showing an example of a functional structure of a basal
body temperature measuring device according to the first
embodiment. FIG. 2 is a view showing an example of an appearance
structure of the basal body temperature measuring device according
to the first embodiment.
[0022] A basal body temperature measuring device 10 according to
the first embodiment is attached to a body of a user for a sleeping
period to measure a basal body temperature. As shown in FIG. 2, a
temperature sensor 11 is provided on a surface of a housing and the
basal body temperature measuring device 10 is attached in such a
manner that the temperature sensor 11 touches a body of a user. For
example, the basal body temperature measuring device 10 is attached
to measure a body temperature in such a manner that the temperature
sensor 11 touches a breast or abdomen part of the user.
[0023] A belt 21 for fixing the basal body temperature measuring
device 10 to a body is provided in such a manner that the basal
body temperature measuring device 10 does not slip down from the
body during sleeping. Although the belt 21 is used herein, a fixing
method is not restricted thereto. For example, a tape or the like
may be used to fix the basal body temperature measuring device 10
to the body.
[0024] As shown in FIG. 1, the basal body temperature measuring
device 10 according to the first embodiment includes, as a
functional structure thereof, the temperature sensor 11, a movement
detecting sensor 12, an information recording unit 13, a storage
medium 14, a basal body temperature specifying unit 15 and a second
information recording unit 16. Function blocks of the information
recording unit 13, the basal body temperature specifying unit 15
and the second information recording unit 16 can be configured from
any of hardware, a DSP (Digital Signal Processor) and software.
[0025] For example, with a structure obtained by the software, each
of the function blocks 13, 15 and 16 actually includes a CPU, an
RAM, an ROM and the like in a computer and is implemented by an
operation of a program stored in a storage medium such as an RAM,
an ROM, a hard disk or a semiconductor memory. The storage medium
for storing the program may be the same as the storage medium 14 or
different therefrom.
[0026] The temperature sensor 11 measures a temperature of a body
of a user during sleeping. The movement detecting sensor 12 detects
a movement of the body of the user during sleeping. The movement
detecting sensor 12 can be configured from an acceleration sensor
as an example. When the body of the user is moved, the acceleration
sensor detects an acceleration generated in the movement and
outputs acceleration information.
[0027] The information recording unit 13 records, in the storage
medium 14, body temperature information to be measured by the
temperature sensor 11 in association with the movement information
(acceleration information) to be detected by the movement detecting
sensor 12. The storage medium 14 is a nonvolatile storage medium
such as a hard disk or a semiconductor memory.
[0028] The association of body temperature information and movement
information can be performed through a measuring time, for example.
Specifically, the information recording unit 13 records, in the
storage medium 14, the body temperature information and the
movement information input from the temperature sensor 11 and the
movement detecting sensor 12 respectively together with a time
stamp at a predetermined time interval (for example, an interval of
30 seconds).
[0029] Information to be used for the association of the body
temperature information and the movement information is not
restricted to the time stamp. For example, it is also possible to
use a simple identifier such as a serial number issued sequentially
every predetermined time interval from start of the measurement in
place of the time stamp.
[0030] The basal body temperature specifying unit 15 analyzes the
movement information recorded in the storage medium 14 to detect
awake timing of the user and specifies body temperature information
measured immediately before the wake timing as a basal body
temperature.
[0031] FIG. 3 is a chart showing an example of processing of the
basal body temperature specifying unit 15. FIG. 3 shows
acceleration information obtained in use of the acceleration sensor
as the movement detecting sensor 12. For easy understanding as an
image, acceleration information in time series obtained by the
movement detecting sensor 12 is shown as a continuous waveform.
However, the acceleration information is actually recorded, in the
storage medium 14, as discrete data every 30 seconds.
[0032] For example, in the case in which the basal body temperature
measuring device 10 is attached to the breast part of the user,
acceleration information about a comparatively small amplitude is
detected by the movement detecting sensor 12 in conformity with a
breathing cycle through the movement of the breast part attendant
on the breathing of the user and is recorded in the storage medium
14 through the information recording unit 13 (periods T1 and T3).
The periods T1 and T3 are periods for which the user is sleeping at
rest without moving user's body.
[0033] When the user turns over during sleeping, moreover,
acceleration information about a comparatively great amplitude is
detected by the movement detecting sensor 12 at that moment and is
recorded in the storage medium 14 through the information recording
unit 13 (the period T2). When the user wakes, furthermore, the
acceleration information about a comparatively great amplitude is
detected by the movement detecting sensor 12 for a long time and is
recorded in the storage medium 14 through the information recording
unit 13 (a period T4).
[0034] The basal body temperature specifying unit 15 detects, as
the wake timing of the user, a start timing of the period T4 for
which the acceleration information about a comparatively great
amplitude continues for a long time based on the acceleration
information shown in FIG. 3 which is recorded in the storage medium
14. Then, the basal body temperature specifying unit 15 specifies,
as a basal body temperature, body temperature information measured
at a timing t immediately before the wake timing. In other words,
the body temperature information recorded in the storage medium 14
in association with a time stamp at the timing t is specified as
the basal body temperature of the user.
[0035] The timing t is a timing included in the period T3 for which
the user is in a resting state. By specifying, as the basal body
temperature, a body temperature recorded at the timing t,
accordingly, it is possible to obtain an accurate basal body
temperature measured in a resting state in which the user is
sleeping.
[0036] The basal body temperature specifying unit 15 notifies the
second information recording unit 16 of the specified basal body
temperature of the user. The second information recording unit 16
records the basal body temperature given from the basal body
temperature specifying unit 15 in the storage medium 14 in
association with calendar information representing a measurement
date. By measuring and recording the basal body temperature every
day, it is possible to grasp a rhythm of a change in the basal body
temperature.
[0037] The information recorded in the storage medium 14 (the body
temperature information and the movement information, and the
specified basal body temperature information) can be output to an
external computer which is not shown and be thus utilized.
Alternatively, it is also possible to provide a display in the
basal body temperature measuring device 10 itself, thereby
visualizing and displaying the information recorded in the storage
medium 14 graphically.
[0038] As described above in detail, in the first embodiment, the
body temperature information to be measured by the temperature
sensor 11 for the sleeping period is recorded in the storage medium
14 in association with the movement information to be detected by
the movement detecting sensor 12 for the same sleeping period and
the movement information recorded in the storage medium 14 is then
analyzed to detect the wake timing of the user, and the body
temperature information measured immediately before the wake timing
is specified as the basal body temperature.
[0039] According to the first embodiment having such a structure,
the body temperature of the user can be measured in a resting state
during sleeping and be recorded in the storage medium 14, and
furthermore, the body temperature recorded immediately before the
waking can be specified as the basal body temperature. Therefore,
it is possible to obtain an accurate basal body temperature
measured in the resting state brought immediately before the
waking.
[0040] As described above, there is a possibility that the basal
body temperature might be changed even if a little body movement is
performed. For this reason, it is desirable to acquire, as the
basal body temperature, a body temperature when the user is
sleeping and his (her) body is not being moved. However, the basal
body temperature is conventionally measured after waking.
Therefore, the basal body temperature cannot be measured in a real
sense. On the other hand, according to the first embodiment, it is
possible to measure a true basal body temperature.
[0041] Although the basal body temperature measuring device 10
includes all of the temperature sensor 11, the movement detecting
sensor 12, the information recording unit 13, the storage medium
14, the basal body temperature specifying unit 15 and the second
information recording unit 16 in the embodiment, the present
invention is not restricted thereto. For example, as shown in FIG.
4, it is also possible to employ a system structure in which a
portable basal body temperature measuring device 10' includes the
temperature sensor 11, the movement detecting sensor 12, the
information recording unit 13 and the storage medium 14 and an
external computer 20 to be connected to the basal body temperature
measuring device 10' by wireless or wire includes the basal body
temperature specifying unit 15, the second information recording
unit 16 and a storage medium 41.
[0042] In this case, the basal body temperature measuring device
10' and the external computer 20 can be connected through a cable
such as a USB (Universal Serial Bus). Alternatively, both the basal
body temperature measuring device 10' and the external computer 20
may include wireless communicating means such as Bluetooth
(registered trademark) or a wireless LAN to enable wireless
transmission of the information recorded in the storage medium 14
from the basal body temperature measuring device 10' to the
external computer 20. Alternatively, both the basal body
temperature measuring device 10' and the external computer 20 may
include internet connecting means to enable upload of the
information recorded in the storage medium 14 from the basal body
temperature measuring device 10' to a server device (not shown) on
internet and download of the information from the server device by
the external computer 20.
Second Embodiment
[0043] Next, a second embodiment of the present invention will be
described with reference to the drawings. FIG. 5 is a block diagram
showing an example of a functional structure of a basal body
temperature measuring device 10A according to the second
embodiment. In FIG. 5, since components having the same reference
numerals as those shown in FIG. 1 have the same functions,
repetitive description will be omitted. An appearance structure of
the basal body temperature measuring device 10A is the same as that
in FIG. 2.
[0044] As shown in FIG. 5, the basal body temperature measuring
device 10A according to the second embodiment further includes a
sleeping state deciding unit 51 as the functional structure.
Moreover, an information recording unit 13A is provided in place of
the information recording unit 13.
[0045] The sleeping state deciding unit 51 decides whether the user
is in a REM sleeping state or non-REM sleeping state based on body
temperature information to be measured by a temperature sensor 11.
The REM sleeping represents a state in which a body is sleeping and
a brain is waking, that is, a state in which sleeping is light. The
non-REM sleep represents a state in which the brain is sleeping,
that is, a state in which sleeping is deep.
[0046] It is known that the REM sleep and non-REM sleep and the
body temperature have a correlation. In other words, when a human
first falls asleep, the body temperature rapidly falls by
approximately one degree and moves into the non-REM sleep to be a
deep sleep. When approximately 90 minutes pass, thereafter, a
transition to the REM sleep which is a light sleep is made. A
rhythm of the non-REM sleep and the REM sleep is set to be a single
sleeping cycle which is repeated four to five times in one night. A
period for the REM sleep is short, that is, approximately 2 to 3
minutes in an initial sleep cycle and is increased every time the
sleep cycle is repeated.
[0047] Also after the body temperature rapidly falls by
approximately one degree immediately after falling asleep, the body
temperature slightly rises or falls. In the movement into the
non-REM sleep, a sweating function becomes active so that the body
temperature falls. On the other hand, when the non-REM sleep is
changed to the REM sleep, the body temperature rises. Accordingly,
the sleeping state deciding unit 51 can decide whether a user is in
the REM sleeping state or the non-REM sleeping state by monitoring
whether the body temperature measured by the temperature sensor 11
is in a falling state or a rising state.
[0048] The information recording unit 13A starts to record the body
temperature information and the movement information in the storage
medium 14 when it is decided by the sleeping state deciding unit 51
that a transition from the non-REM sleeping state to the REM
sleeping state has been made. In the case in which the user
naturally wakes without using an alarm clock or the like, there is
a high possibility that user might wake for a period of the REM
sleep which is a light sleep. When the record into the storage
medium 14 is started when the transition from the non-REM sleeping
state to the REM sleeping state is detected, therefore, it is
possible to measure and record a basal body temperature in a
resting state immediately before waking without performing
unnecessary record as much as possible.
[0049] Since the REM sleep occurs four to five times during
sleeping in one night, the record into the storage medium 14 may be
started when the transition to a fourth REM sleep is detected, for
example. In consideration of how many sleeping cycles are included
during a sleeping time scheduled by the user, alternatively, the
user may designate the start of the record since an n-th (n is a
desirable value of 1 to 5) REM sleep for the basal body temperature
measuring device 10A. As another example, moreover, it is also
possible to perform a recording operation into the storage medium
14 for each REM sleeping period and to prevent the recording
operation from being performed for each non-REM sleeping
period.
[0050] Although the description has been given to the example in
which the REM sleeping state/non-REM sleeping state is decided
based on the body temperature information to be measured by the
temperature sensor 11 in the second embodiment, it is also possible
to decide the REM sleeping state/non-REM sleeping state based on
the movement information to be detected by the movement detecting
sensor 12 in place of or in addition to the body temperature
information.
[0051] As described above, the REM sleep represents a state in
which the body is sleeping and the brain is waking. For this
reason, the body is rarely moved during the REM sleep. On the other
hand, the non-REM sleep represents a state in which the brain is
sleeping, and a muscle supporting the body is being used so that
turn-over can be performed. Accordingly, the sleeping state
deciding unit 51 can decide whether the user is in the REM sleeping
state or the non-REM sleeping state by monitoring whether the
movement of the body is detected by the movement detecting sensor
12.
[0052] Also in the second embodiment, in the same manner as in FIG.
4, it is also possible to employ a system structure including a
basal body temperature measuring device 10A' having a temperature
sensor 11, a movement detecting sensor 12, an information recording
unit 13A, a storage medium 14 and a sleeping state deciding unit
51, and an external computer 20 having a basal body temperature
specifying unit 15, a second information recording unit 16 and a
storage medium 41.
Third Embodiment
[0053] Next, a third embodiment of the present invention will be
described with reference to the drawings. FIG. 6 is a block diagram
showing an example of a functional structure of a basal body
temperature measuring device 10B according to the third embodiment.
In FIG. 6, since components having the same reference numerals as
those shown in FIG. 1 have the same functions, repetitive
description will be omitted. An appearance structure of the basal
body temperature measuring device 10B is the same as that in FIG.
2.
[0054] As shown in FIG. 6, the basal body temperature measuring
device 10B according to the third embodiment further includes a
second sleeping state deciding unit 61 as a functional structure
thereof. Moreover, a second information recording unit 16B is
provided in place of the second information recording unit 16.
[0055] The second sleeping state deciding unit 61 decides whether a
user has been in a REM sleeping state or a non-REM sleeping state
in a measurement timing (a timing t in FIG. 3) of a basal body
temperature specified by a basal body temperature specifying unit
15 based on at least one of body temperature information and
movement information which are recorded in a storage medium 14. The
deciding method is the same as described in the second embodiment.
The second sleeping state deciding unit 61 notifies the second
information recording unit 16B of the decided sleeping state.
[0056] The second information recording unit 16B records, in the
storage medium 14, the basal body temperature specified by the
basal body temperature specifying unit 15 together with information
representing the sleeping state (either the REM sleeping state or
the non-REM sleeping state) decided by the second sleeping state
deciding unit 61.
[0057] As described above, in the case in which the user naturally
wakes without using an alarm clock, there is a high possibility
that the user might wake for a REM sleeping period in which
sleeping is light. However, this does not always occur. By leaving,
as record, whether the basal body temperature measured in the
timing t is obtained during the REM sleep or the non-REM sleep,
therefore, it is possible to grasp whether the recorded basal body
temperature is a lower body temperature during the non-REM sleep or
a higher body temperature during the REM sleep.
[0058] Also in the third embodiment, in the same manner as in FIG.
4, it is also possible to employ a system structure including a
basal body temperature measuring device 10B' having a temperature
sensor 11, a movement detecting sensor 12, an information recording
unit 13 and a storage medium 14, and an external computer 20 having
a basal body temperature specifying unit 15, a second information
recording unit 16B, a storage medium 41 and a second sleeping state
deciding unit 61.
[0059] Although the description has been given to the example in
which the acceleration sensor is used as an example of the movement
detecting sensor 12 and the wake timing of the user is detected
based on the acceleration information shown in FIG. 3 in the first
to third embodiments, the present invention is not restricted
thereto. For example, it is also possible to use an angular
velocity sensor (a gyro sensor) in place of or in addition to the
acceleration sensor.
[0060] For example, in the case in which a posture of the user is
detected by the gyro sensor, the posture is greatly changed when
the user is lying down and sleeping and when he (she) is waking and
standing up. For this reason, the basal body temperature specifying
unit 15 can detect, as awake timing, a time that the posture is
