Description

  The present invention relates to a body temperature measurement system.

  In general, the human body has an inherent rhythm of 24 hours, and the deviation of the rhythm can cause various disorders such as sleep disorder, depression, and orthostatic disorder. For this reason, grasping the rhythm by detecting vital signs of the body is important for preventing these obstacles.

  One of the typical vital signs that can be detected is body temperature. FIG. 11 is a schematic diagram showing changes over time when body temperature is measured at regular time intervals, with the horizontal axis representing time and the vertical axis representing body temperature.

  As shown in FIG. 11, the human body temperature falls after going to bed (in the example of FIG. 11, it falls from 24:00 to 6:00 of the next day) and rises with awakening (in the example of FIG. 11, It rises from 6:00 to 12:00). And it is kept at high temperature from daytime to before bedtime (in the example of FIG. 11 from 12:00 to 24:00) and descends again with bedtime. For this reason, after analyzing the descending state, rising state, and stable state, it is possible to grasp the specific rhythm of the person being measured by calculating the time when the body temperature dropped most and the average body temperature during the day. it can.

  On the other hand, in order to capture a change in body temperature over time, it is indispensable to perform continuous (intermittent short period) measurement with high accuracy. And based on such a background, conventionally, various systems for continuously measuring body temperature have been proposed (see, for example, Patent Document 1).

Special table 2007-530154 gazette

  However, when a continuous measurement is to be performed using a normal electronic thermometer, the person to be measured needs to repeat the measurement spontaneously, which is not convenient for the person to be measured. Further, in the case of a normal electronic thermometer, since measurement must be started manually, there is a problem that measurement cannot be performed while sleeping. On the other hand, it is conceivable to install the measurement part as in Patent Document 1 and automatically perform continuous measurement. However, in order to measure body temperature with high accuracy, It is desirable that this is a closed space that forms a simulated body cavity, and is not suitable for continuous measurement with high accuracy in the case of a measurement site where it is difficult to maintain the closed space, such as the body surface (eg, armpit) It is.

  On the other hand, if the rectum or the like is used as a measurement site, a closed space that forms a pseudo-body cavity can be maintained, so that continuous measurement with high accuracy is possible, but long-time wearing is uncomfortable for the subject. .

  For this reason, in order to grasp the inherent rhythm of the body by grasping changes in body temperature over time, involuntary and automatic measurement is used to make the subject feel uncomfortable. It is desirable that it can be realized without accompanying.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a body temperature measurement system capable of realizing involuntary and automatic measurement without causing the subject to feel uncomfortable.

In order to achieve the above object, a body temperature measurement system according to the present invention has the following configuration. That is,

  As described above, in the body temperature measurement system 100 according to the present embodiment, the body temperature tag 125 is downsized so that the measurement unit 120 is inserted into a plastic bracket that is an orthodontic resin material. For this reason, when the distance from the measurement unit 120 is long, the body temperature tag 125 cannot receive a sufficient power supply. On the other hand, as shown in FIG. 4, when the control unit 110 is mounted, the end surface 118 into which the antenna unit 111 of the RFID reader / writer is inserted is close to the mounting position of the measurement unit 120.

In addition, the output (voltage data, calibration data) from the temperature sensing unit 514 is processed, body temperature data is calculated, and then transmitted to the wireless communication unit 512. In addition, in the semiconductor sensor applied to the sensor unit 521 of the temperature sensing unit 514, a sufficient voltage is required to realize highly accurate body temperature measurement (the storage unit 513 and the control unit 515 are operated). Therefore, it is assumed that the control unit 515 is provided with a power supply circuit (boosting means) for that purpose.

<6. Functional configuration of control unit>
Next, the functional configuration of the control unit 110 will be described. FIG. 6 is a diagram illustrating a functional configuration of the control unit 110.

Or send.

<7. Flow of continuous measurement process>
Next, the flow of the continuous measurement process in the body temperature measurement system 100 will be described with reference to FIGS. FIG. 7 is a flowchart showing the flow of the continuous measurement process in the body temperature measurement system 100, and FIG. 8 is a flowchart showing details of the body temperature measurement process in the continuous measurement process. Further, FIG. 9 is a schematic diagram showing a change (profile) of the body temperature measured with the body temperature measurement system 100 over time.

  When the power source of the control unit 110 is turned on and a continuous measurement process is instructed, the flowchart shown in FIG. 7 is executed. In step S701, the control unit 110 instructs the measurement unit 120 to measure body temperature, and internally sets a default cycle (for example, 10 minutes) as a read cycle for reading data from the measurement unit 120. In step S702, a timer is started based on the internally set readout cycle, and in step S703, it is determined whether or not the time corresponding to the readout cycle has elapsed.

  If it is determined in step S703 that the time corresponding to the read cycle has not elapsed, the process waits until the time corresponding to the read cycle elapses. On the other hand, if it is determined that the time corresponding to the reading cycle has elapsed, the process proceeds to step S704, where body temperature measurement is instructed, and the measurement unit 120 executes body temperature measurement processing.

  Specifically, as shown in FIG. 8, an electromagnetic field is generated from the antenna unit 111 of the control unit 110 and is magnetically coupled to the antenna unit 500 of the body temperature tag 125, thereby causing the body temperature tag from the control unit 110. Power is supplied to 125 (801).

  In the body temperature tag 125 to which power is supplied, the processing unit 510 is activated, and it is determined whether or not the body temperature tag 125 is in a state of affecting the accuracy of body temperature measurement (811). If it is determined that the processing unit 510 is in a state that affects the accuracy of body temperature measurement, the processing unit 510 does not perform the subsequent processing. In this case, the control unit 110 determines that no data is transmitted from the body temperature tag 125 within a certain time after power is supplied, and displays an error on the display unit 112 as a display process (821).

  On the other hand, when it is determined that the body temperature tag 125 is not in a state that affects the accuracy of body temperature measurement, the processing unit 510 starts body temperature measurement processing.

  Specifically, a current is passed through the semiconductor sensor in the sensor unit 521 to detect the band gap voltage (812).

  Further, the circuit unit 522 processes the detected band gap voltage (813), and the control unit 515 acquires the processed voltage data (814).

  Further, the control unit 515 calculates body temperature data based on the acquired voltage data and the calibration data stored in the storage unit 513, and transmits the body temperature data to the control unit 110 via the wireless communication unit 512 (802). ).

  The control unit 110 receives the body temperature data transmitted from the body temperature tag 125, stores it in the storage unit 612 in association with the measurement date and time (time information), and displays it on the display unit 112 (821).

  When the body temperature measurement is completed, the process proceeds to step S705 in FIG. In step S705, based on the body temperature data for a predetermined time stored in the storage unit 612, a change with time in the body temperature of the measurement subject (a stable state, an elevated state, a lowered state) is analyzed.

  In step S706, it is determined whether or not the body temperature of the measurement subject is in a descending state. If it is determined that the body temperature is not in the descending state, the process returns to step S702, and the default period is maintained as the reading period again. Start the timer.

  On the other hand, if it is determined in step S706 that the vehicle is in the descending state, the process proceeds to step S707, and a short cycle (for example, 3 minutes) is internally set as the reading cycle. In step S708, a timer is started based on the newly set read cycle, and in step S709, it is determined whether or not the time corresponding to the read cycle has elapsed.

  If it is determined in step S709 that the time corresponding to the read cycle has not elapsed, the process waits until the time corresponding to the read cycle elapses. On the other hand, if it is determined that the time corresponding to the read cycle has elapsed, the process proceeds to step S710, where body temperature measurement is instructed, and the measurement unit 120 executes body temperature measurement processing. In addition, since the specific process in a body temperature measurement is the same as that of step S704, description is abbreviate | omitted here.

  In step S <b> 711, the temporal change in the body temperature of the measurement subject is analyzed based on the body temperature data for a predetermined time stored in the storage unit 612.

  In step S712, it is determined whether or not the body temperature of the measurement subject is in the rising state. If it is determined that the body temperature is not in the rising state, the process returns to step S708, and the timer is again set while maintaining the short cycle as the reading cycle. Start up.

  On the other hand, if it is determined in step S712 that the vehicle is in the rising state, the process returns to step S701, and the default cycle is set again as the read cycle. Thereafter, the above process is repeated.

  As described above, the control unit 110 determines whether the body temperature of the measurement subject is in the rising state, the stable state, or the falling state by analyzing the change over time of the acquired body temperature data. The reading cycle is changed based on the determination result (see FIG. 9).

  As a result, based on the body temperature data stored in the storage unit 612, it is possible to accurately calculate the time when the body temperature has fallen the most before waking up, which is important for grasping the specific rhythm of the measurement subject. (See FIG. 9).

  In calculating the average body temperature during the day, the number of data points may be smaller than in the case of calculating the time when the body temperature fell most before the awakening. For this reason, in the body temperature measurement system 100 according to the present embodiment, power consumption is suppressed by setting a long daytime reading cycle (see FIG. 9).

As is clear from the above description, the body temperature measurement system 100 according to the present embodiment has the following configuration in order to realize continuous body temperature measurement.
-In order to be able to perform involuntary and automatic measurements, it is configured to be continuously worn by the subject and to start measuring body temperature at a predetermined cycle.
・ In order to eliminate the uncomfortable feeling of the subject while maintaining the closed space during measurement, pay attention to the measurement in the oral cavity, and insert a small body temperature tag into the plastic bracket, which is an orthodontic resin equipment It was.
-Considering the decrease in transmission / reception sensitivity due to the miniaturization of the body temperature tag, the control unit is configured as an ear hook type so that the antenna unit of the RFID reader / writer is arranged in the vicinity of the body temperature tag mounting position. The antenna portion is arranged in the vicinity of the end face of the hook-type control portion.
・ In order to grasp the specific rhythm of the person being measured, it was configured to analyze the changes over time in the acquired body temperature data and change the readout cycle.

  As a result, it has become possible to provide a body temperature measurement system capable of realizing involuntary and automatic measurement without causing the subject to feel uncomfortable.

In addition to the configuration of the mold, the antenna unit is arranged in the vicinity of the end face of the hook-type control unit. However, the present invention is not limited to this. For example, when the measurement subject performs orthodontics, the transmission / reception sensitivity on the body temperature tag side may be improved by using an orthodontic wire having an antenna portion inserted therein.

  FIG. 10A is a diagram illustrating a state in which the measurement unit 1020 constituting the body temperature measurement system according to the present embodiment is mounted.

A plastic bracket is attached.

  In FIG. 10A, reference numeral 1022 denotes a correction wire in which an antenna portion connected to the body temperature tag of the measurement unit 1020 is inserted, and reference numeral 1021 denotes a normal correction wire. As shown in FIG. 10A, the correction wire 1021 is attached to the outer side of the leftmost innermost molar from the plastic bracket attached to the outermost side of the rearmost molar on the right side of the measurement subject. It is stretched up to a plastic bracket (not shown). For this reason, sufficient length as an antenna part is securable. As a result, it is possible to compensate for a decrease in transmission / reception sensitivity due to downsizing of the body temperature tag.

[Third Embodiment]
In the second embodiment, when the subject performs orthodontics, the transmission / reception sensitivity on the body temperature tag side is improved by using an orthodontic wire in which the antenna portion is inserted. Instead of directly adhering the measurement part to the molar tooth, the measurement part may be adhered to the splint by covering the dentition with a resin material splint used for the splint treatment.

  FIG. 10B is a diagram illustrating a state in which the measurement unit 1030 and the sprint 1050 constituting the body temperature measurement system according to the present embodiment are mounted. As shown in FIG. 10B, in the present embodiment, a transparent resin sprint is attached to the upper dentition of the measurement subject, and the measurement unit 1030 is bonded to the outer surface of the sprint 1050 at the innermost molar portion. The

  Since the splint 1050 is detachable from the dentition, the measurement part can be removed from the mouth at any time when the person to be measured feels inconvenience during a meal or the like.

That is, the measurement unit can be inserted into an arbitrary member (intraoral member) attached to the oral cavity of the measurement subject.

[Fourth Embodiment]
In the first embodiment, in order to maintain the closed space at the time of measurement, attention is paid to the measurement in the oral cavity, and the body temperature data is read at a predetermined reading cycle. However, the present invention is not limited to this.

  For example, the measurement subject's oral cavity is not always closed space, and the subject's mouth may be open.In such a state, the acquired body temperature data is also Measurement error is large.

  For this reason, it is desirable that body temperature data acquired in a state where the oral cavity of the measurement subject is not a closed space is excluded from the analysis target.

  Specifically, the plastic bracket, which is an orthodontic resin material, is inserted with an acceleration sensor tag in addition to the body temperature tag 125, and when the measurement unit 120 reads out the body temperature data, the operation of the jaw of the measurement subject The output (acceleration data) of the acceleration sensor tag that detects the error may also be read. With this configuration, when the output of the acceleration sensor tag is equal to or greater than a predetermined threshold, it can be determined that the measurement subject is moving the jaw and the closed space in the oral cavity is not maintained. Because. That is, it is possible to exclude the body temperature data when grasping the unique rhythm of the measurement subject.

  In the above description, the body temperature data is read regardless of the output of the acceleration sensor tag. However, the present invention is not limited to this. For example, when the output of the acceleration sensor tag is equal to or higher than a predetermined threshold value. The body temperature data may not be read out. Specifically, in the determination of whether measurement is possible in step S811 in FIG. 8, when the output of the acceleration sensor tag is equal to or greater than a predetermined threshold, the body temperature tag 125 is in a state of affecting the accuracy of body temperature measurement. It is good also as a structure which determines with having.

[Fifth Embodiment]
In the said 1st Embodiment, although it was set as the structure provided with only 1 type of control parts as a body temperature measurement system, this invention is not limited to this, It is good also as a structure which prepares multiple types. For example, sleeping in a state where an ear hook type control unit is hooked on an auricle may be uncomfortable depending on a person to be measured. Therefore, as the body temperature measurement system, a plurality of types of control units may be prepared, and different control units may be attached according to the activity state of the measurement subject. Thus, even when a plurality of control units are prepared, as long as the time of each control unit is synchronized, it is only necessary to read the body temperature data stored in association with the measurement time in each control unit. In addition, it becomes possible to analyze a change in body temperature over time, and to grasp a specific rhythm of the measurement subject. As a control unit other than the ear-hook type control unit, for example, a configuration in which the function of the control unit is inserted in a pillow so that body temperature data can be acquired at bedtime can be considered.
