Description

  The present invention relates to a body temperature measuring device, method, and program for measuring body temperature.

  When measuring the body temperature of a human body, for example, a temperature sensor is generally inserted into the armpit, sublingual or ear, and measured for a certain period of time. There has also been proposed a method in which a temperature sensor is provided in the blood pressure measurement device, and the temperature in the ear is measured by attaching the blood pressure measurement device to the outer ear (see, for example, Patent Document 1).

JP 2006-204320 A

  However, the conventional measurement technique and the technique described in Patent Document 1 limit the posture and activity of the person being measured during measurement. For this reason, it is difficult to automatically measure and record over a long period of time wearing a temperature sensor. Further, when the surrounding environment such as the outside air temperature or the activity state of the measurement subject is changed, the influence cannot be excluded.

  The present invention has been made paying attention to the above circumstances, and its object is to reduce the influence of at least one of the surrounding environment and the activity state of the subject to be measured, and to enable automatic measurement over a long period of time. It is to provide a measuring apparatus, method and program.

  In order to achieve the above object, a first aspect of the present invention includes a body temperature measurement unit that is mounted on a predetermined measurement site of a person to be measured and measures the body temperature of the person to be measured, and an outside air temperature around the person to be measured. In the body temperature measuring device connected to the temperature measuring unit to be measured, information representing the body temperature of the measurement subject measured by the body temperature measuring unit is received from the body temperature measuring unit at a preset measurement time interval. The information representing the outside air temperature measured by the air temperature measurement unit in the same period as the body temperature measurement period by the body temperature measurement unit is received. And based on the information representing the received outside air temperature, the information representing the received body temperature is corrected so as to reduce the change in the skin temperature of the measurement site due to the outside air temperature included in the information, Information indicating the corrected body temperature is stored in a storage medium.

  According to a second aspect of the present invention, there is provided a body temperature measuring unit that is attached to a predetermined measurement site of the subject and measures the body temperature of the subject, and an acceleration that is attached to the subject and measures the acceleration of the subject. In the body temperature measurement device connected to the measurement unit, first, information representing the body temperature of the measurement subject measured by the body temperature measurement unit is received from the body temperature measurement unit, and the acceleration measurement is performed from the acceleration measurement unit. Information representing the acceleration of the measurement subject measured by the unit is received. Next, the activity state of the measurement subject is estimated based on the information representing the received acceleration, and it is determined whether the measurement subject is in an exercise state or in a resting state. And the information showing the body temperature measured by the said body temperature measurement part in the period determined as the said to-be-measured person being in a resting state is selected as a preservation | save object.

  Each means described in the second aspect may be added to each means described in the first aspect.

  According to a third aspect of the present invention, an amount of change in body temperature is calculated between pieces of information representing body temperature received at the measurement time interval, and the measurement time interval is variably controlled according to the calculated amount of change in body temperature. Means or process is further provided.

  According to the first aspect of the present invention, the information representing the body temperature measured by the body temperature measuring unit is corrected so that the change in skin temperature due to the outside air temperature included in the information is reduced. For this reason, the influence of the change in the skin temperature due to the outside air temperature is reduced, and thereby the measurement accuracy can be increased.

  According to the second aspect of the present invention, the activity state of the measured person is estimated based on the received information representing the acceleration, and it is determined whether the measured person is in an exercise state or in a resting state. And the information showing the body temperature measured by the body temperature measurement part is selected as a preservation | save object in the period when it was determined that the to-be-measured person is in a resting state. For this reason, only the body temperature measured during the period in which it was determined that the person being measured is in a resting state will be stored, for example, to avoid misrecognizing an increase in body temperature due to exercise as an increase in body temperature due to disease. Is possible.

  According to the third aspect of the present invention, the measurement time interval is variably controlled in accordance with the amount of change in body temperature measured at a preset time interval. For this reason, for example, in a steady state, the measurement information amount is suppressed by setting the measurement time interval to be relatively long. On the other hand, if the amount of change in the measured value of the body temperature exceeds the threshold value, the measurement time interval is It is possible to accurately monitor changes in body temperature by changing the length to a short one.

  That is, according to each aspect of the present invention, it is possible to provide a body temperature measuring device, method, and program capable of reducing the influence of at least one of the surrounding environment and the activity state of the measurement subject and enabling automatic measurement over a long period of time. it can.

[One Embodiment]
(Constitution)
FIG. 1 is a block diagram showing the configuration of a body temperature measuring device and its peripheral devices according to an embodiment of the present invention. 1 is a body temperature measuring device, 2 is a measuring unit, and 3 is an external storage device. . Among these, the body temperature measurement device 1 and the measurement unit 2 are accommodated in the same housing, and the external storage device 3 is provided separately. The body temperature measuring device 1 and the external storage device 3 are connected via a short-range wireless communication interface such as Bluetooth (registered trademark).

  The measurement unit 2 may be housed in a separate housing from the body temperature measuring device 1, and in this case, the body temperature measuring device 1 is connected via a short-range wireless communication interface such as Bluetooth (registered trademark). By doing so, measurement data can be transmitted to the body temperature measuring device 1.

  The measurement unit 2 includes an acceleration measurement unit 21, a body temperature measurement unit 22, and an air temperature measurement unit 23. For example, an infrared temperature sensor is used for the body temperature measurement unit 22. For example, a triaxial acceleration sensor is used for the acceleration measuring unit 21. For example, an IC temperature sensor is used for the air temperature measurement unit 23. The acceleration data, body temperature data, and outside air temperature data measured by these measuring units 21, 22, and 23 are input to the body temperature measuring device 1 through signal lines.

  The external storage device 3 has a non-volatile storage medium such as SSD (Solid State Drive) that can be written and read at any time, and is used to store various data necessary for processing including body temperature measurement data. . As described above, data communication is performed between the external storage device 3 and the body temperature measurement device 1 via a short-range wireless communication interface such as Bluetooth (registered trademark).

  The body temperature measuring device 1 is connected between a control unit having a CPU (Central Processing Unit) and a working memory, and the measuring unit 2 and the external storage device 3 via a short-range wireless communication interface such as Bluetooth (registered trademark). A communication interface for performing data communication and a clock generator 17 are provided.

  The control unit 2 includes, as processing functions for carrying out this embodiment, an activity state determination unit 11, a body temperature data acquisition unit 12, an outside air temperature data acquisition unit 13, a temperature correction processing unit 14, and a data storage control unit. 15 and a sampling rate control unit 16. These functions are realized by causing the CPU to execute a program stored in a program memory (not shown).

  The activity state determination unit 11 takes in the triaxial acceleration data from the acceleration measurement unit 21 via the communication interface, and estimates the activity state of the measurement subject by performing filtering processing on the obtained triaxial acceleration data. And the process which determines whether a to-be-measured person is an exercise state or a resting state is performed by comparing the estimated value with a threshold value. The three-axis acceleration data capturing period is set to a value shorter than a body temperature data capturing period, which will be described later, based on the clock generated from the clock generator 17.

  The body temperature data acquisition unit 12 captures body temperature measurement data from the body temperature measurement unit 22 via the communication interface at a period set based on the clock generated from the clock generation unit 17. Then, based on the determination result of the activity state determination unit 11 for the acquired measurement data of the body temperature, the activity state of the measurement subject at the time of measurement of the body temperature data, that is, the “exercise state” or “rest” A process of assigning information indicating whether or not the state is a label is performed.

  The outside air temperature data acquisition unit 23 performs processing for taking in the outside air temperature measurement data from the air temperature measurement unit 23 via the communication interface in synchronization with the taking-in timing of the body temperature measurement data.

The temperature correction processing unit 24 has the following processing functions.
(1) A process of calculating a correction value ΔT for correcting a difference between the temperature measured by the body temperature measurement unit 22 and the actual body temperature in the initial setting mode.
(2) In the initial setting mode, the body temperature measuring unit 22 and the air temperature measuring unit 23 measure the body temperature of the person to be measured and the ambient air temperature around the subject at least twice under different outside air temperatures, and the difference between the measured body temperatures A process of calculating a temperature correction value ΔTout according to the outside air temperature based on the difference between the outside air temperatures.
(3) In the actual body temperature measurement mode, the body temperature measurement data labeled “rest” is selected from the body temperature measurement data captured from the body temperature measurement unit 22 by the body temperature data acquisition unit 12. And the process which correct | amends this selected body temperature measurement data based on correction value (DELTA) T and (DELTA) Tout calculated by said (1) and (2).

  The data storage control unit 15 associates the temperature measurement data corrected by the temperature correction processing unit 14 with a time stamp indicating the measurement time, and then transmits and stores the temperature measurement data to the external storage device 3 via the communication interface. Do.

  The sampling rate control unit 16 first calculates a temperature change amount during sampling of the body temperature measurement data corrected by the temperature correction processing unit 14. Then, the calculated temperature change amount is compared with a threshold value, and if it is equal to or less than the threshold value, the temperature measurement data capturing period is set to a relatively long first period. A process for variably setting the sampling rate for capturing the temperature measurement data is performed so that each measurement data is captured at a second period shorter than the first period. In addition, the change period of the external temperature measurement data is also changed following the change of the acquisition period of the temperature measurement data.

(Operation)
Next, the body temperature measurement operation by the apparatus configured as described above will be described.
(1) Initial setting mode (1-1) Setting of correction value for correcting difference between temperature measured by temperature measuring unit 22 and actual body temperature First, using a commercially available thermometer, Body temperature is measured under the tongue or in the ear. Then, the measured temperature data at this time is temporarily stored in the external recording device 3 as Tbody0 (° C.), taken into the body temperature measuring device 1 using a communication interface, and stored in the working memory. The temperature measurement may be performed using the body temperature measurement unit 22 of the measurement unit 2 under the measurement subject's armpit, sublingual or in the ear.

  Next, a case containing the body temperature measurement device 1 and the measurement unit 2 is attached to an arbitrary part of the measurement subject, and the temperature is measured. For example, as shown in FIGS. 2 (a) and 2 (b), a part such as a wrist or an ankle that hardly disturbs the normal movement of the measurement subject is selected as the attachment part. The body temperature data measured by the body temperature measuring unit 22 of the measurement unit 2 is taken into the body temperature measuring device 1 as T0 (° C.) and stored in the working memory.

The difference ΔT (° C.) between the body temperature data Tbody0 previously measured in the armpit, sublingual or in the ear and the body temperature data T0 measured by the measurement unit 2 at the wearing site is a temperature correction process. In section 14, ΔT = Tbody0−T0
And is stored in the working memory as a temperature correction value. This temperature correction value ΔT is equal to the body temperature T (° C.) measured by the measurement unit 2 at the measurement site 2 in the actual body temperature measurement mode to be described later. Tbody = T + ΔT
Is added as Tbody indicates the body temperature after correction.

For example, the body temperature Tbody0 measured under the measurement subject's armpit is 36.5 ° C. and measured by the body temperature measurement device 1 with the measurement unit 2 attached to the measurement subject's wrist as illustrated in FIG. If the wrist temperature T is 34 ° C., the correction value ΔT is ΔT = 36.5-34.
= 2.5 ° C
It becomes. Therefore, the corrected body temperature Tbody in this case is T + 2.5 (° C.) with respect to the measured value T (° C.).
In order to further improve the correction accuracy, the correction value ΔT may be calculated a plurality of times to obtain an average value of ΔT.

(1-2) Setting of correction value for skin temperature change due to outside air temperature In order to correct the skin temperature change due to the outside air temperature, the body temperature measuring unit 22 and the air temperature measuring unit 23 use the body temperature measuring unit 22 and the air temperature measuring unit 23 to measure the body temperature of the person being measured Must be measured at least twice under different outside air temperatures, and a temperature correction value ΔTout based on the outside air temperature must be calculated based on the difference between the measured body temperature and the outside air temperature.

For example, the body temperature of the subject measured by the first measurement and the outside temperature at that time are Tout0 and T0, respectively, and the body temperature of the subject measured by the second measurement and the outside temperature at that time are Tout1 and T1, respectively. Then, the temperature correction value ΔTout by the outside air temperature is ΔTout = (T1−T0) / (Tout1−Tout0)
It becomes.

Therefore, in the body temperature measurement mode to be described later, the body temperature T measured by the body temperature measuring unit 22 of the measurement unit 2 based on the correction value ΔTout of the outside air temperature and the correction value ΔT for the body temperature obtained previously is:
Tbody = T + ΔT−ΔTout × (Tout1−Tout0) (1)
As corrected.

In addition, when correction by N times (N> 2) measurement is added, when the outside air temperature at the time of measurement is Tout (° C.) as Tout0, Tout1, Tout2,. Using the value Toutk1 closest to Tout and the next value Toutk2 next, ΔT is obtained as follows. That is, if the measured temperature at Toutk1 is Tk1, and the measured temperature at Toutk2 is Tk2,
ΔTout = (Tk2-Tk1) / (Toutk2-Toutk1)
Is calculated as

(1-3) Initial Setting of Sampling Rate Generally, since the body temperature does not change abruptly, the sampling rate when capturing body temperature measurement data from the body temperature measuring unit 22 is set to a small value, and when measuring data is captured from the acceleration measuring unit 21 The sampling rate is set to a value larger than the sampling rate of the body temperature measurement unit 22. For example, the sampling rate of the body temperature measurement unit 22 is set to 0.1 Hz, and the sampling rate of the acceleration measurement unit 21 is set to 10 Hz.

(2) Actual Body Temperature Measurement Mode When the body temperature measurement mode is set, the body temperature measurement device 1 performs the following processing. FIG. 3 is a flowchart showing the basic processing procedure and processing contents.
(2-1) Determination of activity state Since body temperature varies depending on the activity state, it is necessary to distinguish between body temperature during exercise and body temperature during rest. Therefore, first, under the control of the activity state determination unit 11, the triaxial acceleration data is acquired from the acceleration measurement unit 21, and the activity state of the measurement subject is estimated by filtering the acquired triaxial acceleration data. Then, by comparing the estimated value with a threshold value in step S11, it is determined whether the subject is in an exercise state or in a resting state.

For example, the activity state of the measurement subject is estimated by performing a process of passing the digital high-pass filter on the measurement values x, y, and z of the triaxial acceleration data. Now, assuming that the raw data of the acceleration measuring unit 21 at time t is x, y, z and the sampling interval is ts, the values x (t), y (t), z (t) subjected to processing through a high-pass filter are used. Is
x (t) = x− (x × 0.1 + x (t−ts) × 0.9)
y (t) = y− (y × 0.1 + y (t−ts) × 0.9)
z (t) = z− (z × 0.1 + z (t−ts) × 0.9)
It becomes.

  Next, a total value of absolute values of the triaxial acceleration data x (t), y (t) and z (t) after the processing through the high-pass filter is obtained, and this total value is preset. If it is greater than or equal to the threshold value k, it is determined as “exercise state” in step S14, and if it is less than the threshold value, it is determined as “rest state” in step S12.

  Further, when determining the “sleep state”, an acceleration threshold value ksleep and a time threshold value ksleeptime for sleep state determination are set in advance. If the sum of the absolute values of the triaxial acceleration values x (t), y (t) and z (t) after the filtering process is smaller than ksleep and the duration is longer than ksleeptime, “sleep” State ".

(2-2) Measurement of body temperature Next, in step S13, under the control of the body temperature data acquisition unit 12, body temperature measurement data is taken in from the body temperature measurement unit 22 via the communication interface. Then, based on the determination result of the activity state determination unit 11 for the acquired measurement data of the body temperature, the activity state of the measurement subject at the time of measurement of the body temperature data, that is, the “exercise state” or “rest” Information indicating whether it is “state” or “sleep state” is associated as a label.

(2-3) Measurement of outside air temperature In addition, in step S15, under the control of the outside air temperature data obtaining unit 13, the temperature measuring unit 23 communicates with the timing of capturing the body temperature measurement data via the communication interface. Capture measurement data of outside temperature.

(2-4) Correction of body temperature Subsequently, in step S16, under the control of the temperature correction processing unit 14, the body temperature measurement data acquired in step S13 is compared with the outside air temperature measurement data acquired in step S15 and the previous. The corrected body temperature measurement data Tbody is calculated by substituting into the equation (1) together with the correction values ΔT and ΔTout set in the initial setting mode. Thus, the error of the measured value by the body temperature measuring unit 12 with respect to the body temperature and the error due to the influence of the outside air temperature are corrected. The corrected body temperature measurement data Tbody is stored in a storage memory in the body temperature measuring device 1 with a time stamp indicating the measurement time.

(2-5) Control of Sampling Rate Next, under the control of the sampling rate control unit 16, sampling rate change control is performed as follows. That is, first, in step S17, a temperature change amount during sampling of the body temperature measurement data corrected by the temperature correction processing unit 14 is calculated, and the calculated temperature change amount is compared with a threshold value. As a result of the comparison, if the temperature change amount is equal to or smaller than the threshold value, the sampling rate (for example, 0.1 Hz) that is initially set for measuring body temperature is maintained. On the other hand, when the temperature change amount exceeds the threshold value, the body temperature measurement sampling rate is changed to a value larger than the initial set value in step S18.

For example, suppose that the sampling rate is s, the sampling interval is ts, the threshold value for determining a change in temperature measurement value is ks, and the temperature measurement value at time t is f (t).
| F (t) −f (t-ts) | ≦ ks
If so, the sampling rate remains s. In contrast,
| F (t) -f (t-ts) |> ks
Then, the sampling rate is s × (| f (t) −f (t-ts) |) / ks
Changed to

(2-6) Recording of Body Temperature Measurement Data Finally, under the control of the data storage control unit 15, the corrected body temperature measurement data stored in the storage memory in the body temperature measuring device 1 is read out in step S19. And transmitted to the external storage device 3 via the communication interface. When the external storage device 3 receives the body temperature measurement data, the external storage device 3 records the received body temperature measurement data in time series in accordance with a time stamp. The data storage control unit 15 deletes the body temperature measurement data stored in the storage memory in the device every time a certain storage period elapses.

Next, a more specific embodiment of the body temperature measuring operation described above will be described.
Example 1
Example 1 is an example in the case where the body temperature measurement device 1 is used for detection of a cold.
Body temperature generally varies about 0.5 ° C. per day. When the temperature is higher than the normal temperature at rest by 1 ° C. or more, the person being measured may have a cold. Therefore, an early response to the cold can be made by notifying the person to be measured at that time by an alarm or the like.

  The body temperature measurement device 1 in which the measurement unit 2 is incorporated is attached to the wrist of the person to be measured as illustrated in FIG. In the initial setting mode, the body temperature of the person to be measured during normal heat is measured and stored in a working memory in the apparatus. Or the value which averaged the body temperature on the 1st is preserve | saved as normal heat.

In the actual measurement mode, the body temperature measuring device 1 performs the following processing. FIG. 4 is a flowchart showing the processing procedure and processing contents.
That is, first, in step S21, under the control of the activity state determination unit 11, triaxial acceleration data is captured from the acceleration measurement unit 21, and the captured triaxial acceleration data is filtered to determine the activity state of the measurement subject. And the estimated value is compared with a threshold value. As a result of this comparison, if the estimated value is greater than or equal to the threshold value, it is determined as “exercise state” in step S31, and the process ends. That is, the body temperature and the outside air temperature are not measured in the exercise state, and as a result, an increase in the data capacity in the storage memory in the apparatus can be suppressed.

  On the other hand, if the estimated value is less than the threshold value as a result of the comparison, it is determined as “resting state” in step S22, and the time is stored. When it is detected that this “rest state” continues for 30 minutes or more, measurement data of the skin temperature of the wrist of the measurement subject 22 from the body temperature measurement unit 22 under the control of the body temperature data acquisition unit 12 in step S23. Is captured. In parallel with this, in step S24, under the control of the outside air temperature data acquisition unit 13, the measurement data of the temperature around the measurement subject is taken in from the temperature measurement unit 23.

  Next, in step S25, under the control of the temperature correction processing unit 14, the measured body temperature is corrected based on the measured outside air temperature and preset correction values ΔT and ΔTout. By this correction processing, the error of the measured value by the body temperature measuring unit 12 with respect to the body temperature and the error due to the influence of the outside air temperature are corrected. The corrected body temperature measurement data is stored in a storage memory in the apparatus.

  Subsequently, in step S26, the measured body temperature in the resting state is compared with the normal temperature stored in advance in the initial setting, and it is determined whether or not the body temperature is higher by 1 ° C. than the normal temperature. As a result of this determination, if the measured body temperature is 1 ° C. or more higher than the normal temperature, an alert is output in step S27. As an alert output method, there are a method in which a vibration motor is attached inside and notified by vibration, and a method in which an LED is attached to the exterior and notified by light.

  If the amount of change in the measured body temperature sampling exceeds the threshold value, the sampling rate for capturing the body temperature measurement data in step S29 is higher under the control of the sampling rate control unit 16. To be changed. For this reason, body temperature is measured at a shorter cycle thereafter.

  As a result of the determination, if the measured body temperature is lower or higher than normal temperature and the difference is less than 1 ° C., the sampling rate is controlled in steps S28 and S29 without generating an alert. In step S30, the body temperature measurement data corrected in step S25 is temporarily stored in the storage memory in the apparatus, and then is read and transmitted to the external storage device 3 for every predetermined period.

(Example 2)
Example 2 is an example in the case of using the body temperature measuring device 1 as a basal thermometer.
Basal body temperature is the body temperature during basal metabolism, and it is desirable to measure the body temperature when sleeping. The determination of the sleep state from when the measurement subject goes to sleep to when he / she wakes up is performed based on the triaxial acceleration data measured by the acceleration measurement unit 21. The average of the measured body temperature during sleep is defined as the basal body temperature, and the basal body temperature is corrected by correcting the error of the measured value by the body temperature measuring unit 12 with respect to the body temperature and the error due to the influence of the outside air temperature. Are transmitted to the external storage device 3 and stored. In this way, the basal body temperature can be automatically recorded.

  In other words, using this body temperature measuring device can save the labor of measuring the body temperature every morning as in the past, and more accurate basal body temperature by taking an average value of the body temperature during sleep. Be able to get. Moreover, if it is worn on the wrist or ankle, the burden on sleeping is small.

(Effect of embodiment)
As described in detail above, in this embodiment, the activity state of the measurement subject is estimated based on the triaxial acceleration data measured by the acceleration measuring unit 21 to determine whether the subject is in an exercise state or in a resting state. The body temperature measurement data measured by the body temperature measurement unit 22 in a resting state is corrected together with the outside air temperature measurement data simultaneously measured by the air temperature measurement unit 23 and previously set correction values ΔT and ΔTout. By substituting into the arithmetic expression (formula (1)), the measurement data of the body temperature is corrected, and the corrected body temperature measurement data is stored. Further, when the amount of change between the samplings of the corrected body temperature measurement data exceeds the threshold value, the sampling rate for taking in the body temperature measurement data becomes higher under the control of the sampling rate control unit 16. I am trying to change it.

  Therefore, only the body temperature measured during the period in which it is determined that the measurement subject is in a resting state is stored. For example, the increase in body temperature due to exercise is not mistakenly recognized as the increase in body temperature due to illness. It becomes possible. Further, the correction is made so that the error of the measurement value by the body temperature measurement unit 12 with respect to the body temperature and the error due to the influence of the outside air temperature included in the body temperature measurement data are removed. For this reason, it becomes possible to improve the measurement accuracy of body temperature. Furthermore, the sampling rate is variably controlled according to the amount of change in body temperature per unit time. For this reason, for example, in a steady state, by setting the sampling rate low, the amount of measurement data is suppressed. On the other hand, if the amount of change in the measured value of body temperature exceeds the threshold, the sampling rate is increased. It becomes possible to accurately monitor changes in body temperature in a short cycle.
