Description

The present invention relates to a biometric information system, a biometric information measuring device, a biometric information control device, and a biometric information processing method, and more particularly, a biometric information system, a biometric information measuring device, and a biological information for appropriately managing measurement date and time information. The present invention relates to a control device and a biological information processing method.

In recent years, in the medical field, biological information of a subject is measured by using a measuring device such as a pulse oximeter, a thermometer, a glucose meter, and an activity meter, and the measured value is controlled by a personal computer or the like together with measurement date and time information. The device acquires and manages the biometric information of the subject. Furthermore, by sharing medical data within the hospital or in the community, high-quality and efficient medical care is being promoted, and a system for linking electronic medical records and biometric information data has been constructed. In such a system, the medical practice and the measured value of each biometric information are managed in association with each other on the electronic medical record, and the measurement date and time information plays an important role as the basis for the association.

The measurement date and time information is important information indicating the date and time when the biological information was measured, and is determined by the clock information held by the measuring device. However, the clock information held by the measuring device may differ from the correct clock information held by the control device due to time reset due to battery replacement or forgetting to set the date and time. In this case, correct measurement is performed. It is difficult to obtain date and time information.

Therefore, even if the clock information held by the measuring device is reset, the following biometric information processing system that corrects the measurement date and time information stored in the measuring device to the measurement date and time information that matches the correct time information has been proposed. ing. This biometric information processing system provides the measuring device with a flag setting means for setting flag information indicating that the measurement date and time is a tentative date and time when the clock information of the measuring device is reset. If the control device determines that the measurement date and time transmitted from the measurement device is a tentative date and time by analyzing the flag information, the measurement included in the measurement data is based on the time difference from the clock information of the control device. A data correction means for correcting the date and time information to the correct measurement date and time is provided (see Patent Document 1 below).

Next, the approximate functions of these components will be described, and then the detailed functions of each component will be described along with the date and time information management procedure and the measurement processing procedure.

<Date and time information management department 11>
The date and time information management unit 11 updates the date and time information held and managed by the date and time management unit 102. Further, the date and time information management unit 11 generates the provisional date and time information [F] depending on the type of the date and time information update processing, and cancels the generated provisional date and time information [F]. Specifically, when the date and time information of the date and time management unit 102 is changed, the provisional date and time information [F] is generated. If the date and time information of the date and time management unit 102 is a synchronous process for the control side date and time information received by the communication unit 106, the provisional date and time information [F] is canceled. The procedure for managing the date and time information by the date and time information management unit 11 will be described in detail below.

Further, the date and time information management unit 11 automatically describes the above when the biometric information measuring device 100 and the control device 200 are in a communication state via the communication unit 106 while the provisional date and time information [F] is being generated. It may be configured to carry out the synchronous processing of. In addition to this, it is possible to adopt a configuration in which synchronization processing is performed after authentication processing without performing synchronization processing even when communication is possible. The former has the advantage of being efficient without hassle, and the latter can confirm the presence or absence of synchronization processing, so it is possible to confirm whether there is a problem in device management, especially the delay of the date and time information of the date and time management unit 102.

The counting of the number of valid data [E] by the valid data number counting unit 12 will be described in detail below.

<Measurement control unit 13>
The measurement control unit 13 controls the measurement of biological information by the measurement unit 101 according to the operation of the operation unit 108.

<Measurement data input / output processing unit 14>
The measurement data input / output processing unit 14 is a unit that stores the measured value [d] obtained by the measurement by the measuring unit 101 in the storage unit 107 and transmits it from the communication unit 106. The measurement data input / output processing unit 14 stores the measured value [d] obtained by the measurement by the measurement unit 101 in the storage unit 107 as measurement data associated with other information. The other data constituting the measurement data together with the measured value [d] is data associated with the data ID [I], the measurement date / time [T], and the provisional date / time information [F].

Of these, the data ID [I] is data that also serves as data indicating the order in which the measurement was performed by the measurement unit 101, and is a unique value. Here, for example, data ID [I] is assigned as measurement order data indicating the measurement order counted from the latest measurement. In this case, the data ID [I] has a numerical value portion that is counted up each time the measurement is performed, or a data portion corresponding to the numerical value portion of the already assigned data.

Further, in the measurement data, the measurement date / time [T] is the date / time information in which the measurement was performed by the measurement unit 101, and is the date / time managed by the date / time management unit 102. Further, the tentative date / time information [F] constituting the measurement data is the current tentative date / time information [F] held in the storage unit 107 at the time when the measurement is performed by the measurement unit 101.

Further, when the communication unit 106 receives the request for transmission of the measurement data, the measurement data input / output processing unit 14 causes the communication unit 106 to transmit the measurement data including the measurement value [d] from the communication unit 106. At this time, the communication unit 106 transmits the current number of valid data [E] held in the storage unit 107 or the RAM 105 together with the measurement data.

<Procedure for managing date and time information performed by the biological information measuring device (1)>
FIG. 4 is a flowchart illustrating a procedure (No. 1) of date and time information management carried out by the biometric information measuring device according to the embodiment. The date and time information management procedure (No. 1) shown in this flowchart is also a part of the biometric information processing method implemented by the biometric information processing system 1, and is performed by the functions of the date and time information management unit 11 and the valid data number counting unit 12. Will be done. The procedure will be described below with reference to the functional configuration diagram of FIG.

[Step S101]
First, in step S101, the date / time information management unit 11 starts the process for managing the date / time information, triggered by the occurrence of the date / time update event. Here, the occurrence of the date and time update event means (1) reception of control side date and time information from the control device 200, (2) reset and setting operation of date and time information in the operation unit 108, and (3) biometric information measurement device 100. This is any one of the battery Ba insertion / removal operations.

[Step S102]
Next, in step S102, the date and time information management unit 11 executes the update process of the date and time information held and managed by the date and time management unit 102. Specifically, the date / time information management unit 11 executes the date / time information update process as follows, depending on the type of the date / time update event.

That is, when the date / time update event in step S101 is (1) reception of the control side date / time information from the control device 200, the date / time information management unit 11 is the control side held by the control device 200 received by the communication unit 106. The date and time information held and managed by the date and time management unit 102 is synchronized with the date and time information. As a result, the date and time management unit 102 can hold accurate date and time information as well as the control side date and time information.

When the date / time update event is (2) resetting or setting the date / time information in the operation unit 108, the date / time information management unit 11 is held and managed by the date / time management unit 102 according to the operation of the operation unit 108. Reset the date and time information or change it to the set date and time. Here, when the operation unit 108 performs an operation to reset the date and time information, the date and time information of the date and time management unit 102 is set to a predetermined initialization time (for example, 00:00 on January 1, 2010). Perform the change process to initialize to.

Further, when the date / time update event is (3) the operation of inserting / removing the battery Ba from the biometric information measuring device 100, the date / time information management unit 11 resets the date / time information held and managed by the date / time management unit 102. , A change process for initializing at a predetermined initialization time (for example, 00:00 on January 1, 2010) is carried out.

[Step S103]
In step S103, the date and time information management unit 11 determines whether or not the type of date and time information update processing in step S102 is synchronization of date and time information. Then, if it is determined that the synchronization is (YES), the process proceeds to step S104, and if it is determined that the synchronization is not (NO), the process proceeds to step S105. As a result, the update process in step S102 is a synchronization process only when the date and time information held in the date and time management unit 102 is synchronized with the accurate date and time received by the communication unit 106 (YES). Is determined, and the process proceeds to step S104.

[Step S104]
In step S104, the date and time information management unit 11 executes a process of setting the provisional date and time information [F] to "0". Here, the provisional date / time information [F] is data indicating whether or not the date / time information held in the date / time management unit 102 is accurate date / time information. Here, in step S102, since the date and time information of the date and time management unit 102 is synchronized with the accurate control side date and time information received by the communication unit 106, it is determined that the date and time information of the date and time management unit 102 is accurate. To. Therefore, the process of setting the provisional date / time information [F] to "0" is performed. Note that setting the tentative date / time information [F] to "0" corresponds to a process of canceling and extinguishing the tentative date / time information [F] generated at that time. The cancellation process in this case may be a process of completely erasing, or may be a process of erasing on the surface, which is associated and saved as past data and stored in a state where it can be referred by the administrator authority. In the case of the process of completely erasing, there is an effect that the amount of data is small and the data is simplified and less confused. In the case of the process of erasing on the surface, there is an effect that the reliability of the data is improved by surely tracing back to the past operation. In this case, it is preferable that the control device 200 can be referred only by a separate operation or the like so that it is not confused, and when the data is referred to by the biometric information measuring device 100, the data is not normally displayed.

Then, for example, the tentative date / time information [F] held in the storage unit 107 or the RAM 105 of the biological information measuring device 100 is rewritten with the tentative date / time information [F] (= 0).

[Step S105]
On the other hand, as described above, in step S103, in step S105, when it is determined that the type of updating the date and time information is not synchronization of the date and time information (NO), the date and time information management unit 11 sets the provisional date and time information [F] to "F". 1 ”is carried out. As a result, provisional date and time information [F] (= 1) indicating that the current date and time information held in the date and time management unit 102 is not accurate date and time information is given as the current provisional date and time information [F]. To. Then, in the subsequent recording of the measurement data by the measurement unit 101, the provisional date and time information [F] (= 1) is similarly held in the storage unit 107 or the RAM 105. Note that setting the tentative date / time information [F] to "1" corresponds to a process of generating the tentative date / time information [F].

[Step S106]
After that, in step S106, the valid data number counting unit 12 cancels the counted up valid data number [E] and sets it to “0”. That is, the valid data number counting unit 12 cancels the valid data number [E] when the date and time information change processing of the date and time management unit 102 is not the synchronization of the date and time information. Then, the valid data number counting unit 12 rewrites the valid data number [E] held in the storage unit 107 to “0”.

[Step S107]
After step S104 or step S106, the date and time information management unit 11 or the valid data number counting unit 12 ends the process in step S107.

<Procedure for managing date and time information performed by the biometric information measuring device (Part 2)>
FIG. 5 is a flowchart illustrating a procedure (No. 2) of date and time information management performed by the biometric information measuring device according to the embodiment. The date and time information management procedure (No. 2) shown in this flowchart is also a part of the biometric information processing method implemented by the biometric information processing system 1, and is performed due to the processing by the measurement data input / output processing unit 14. To. Hereinafter, the procedure will be described by exemplifying a case where wireless communication is used as the communication unit 106 with reference to the functional configuration diagram of FIG.

[Step S201]
First, in step S201, the measurement data input / output processing unit 14 starts the process for managing the date and time information by using the occurrence of the above-mentioned measurement data transmission event as a trigger. Here, the occurrence of a transmission event is a request reception of measurement data transmission in the communication unit 106.

[Step S202]
In step S202, the measurement data input / output processing unit 14 transmits the measurement data from the communication unit 106 in accordance with the request for the measurement data transmission.

[Step S203]
Next, in step S203, the valid data number counting unit 12 performs a process of canceling the valid data number [E] and setting it to “0”. Therefore, the current number of valid data [E] held in the storage unit 107 is “0”.

[Step S204]
In step S204, the measurement data input / output processing unit 14 ends the processing.

<Measurement processing procedure>
FIG. 6 is a flowchart illustrating a measurement process performed by the biological information measuring device according to the embodiment. The measurement process shown in this flowchart is also a part of the biometric information processing method performed by the biometric information processing system 1, and is a series of processing procedures performed in the normal measurement performed by the control unit 10. The procedure will be described below with reference to the functional configuration diagram of FIG.

[Step S301]
First, in step S301, the control unit 10 starts the measurement process of an example by using the occurrence of the measurement event as a trigger. The occurrence of a measurement event is an operation of starting measurement by operating the operation unit 108.

[Step S302]
First, in step S302, the measurement control unit 13 measures the biological information by the measurement unit 101.

[Step S303]
In step S303, the measurement data input / output processing unit 14 counts up the data portion corresponding to the measurement order data in each measurement data already stored in the storage unit 107. Here, for example, the corresponding portion of the data ID [I] is counted up and rewritten.

[Step S304]
In step S304, the measurement data input / output processing unit 14 includes the measurement value [d] obtained by the measurement unit 101, the data ID [I], the measurement date and time [T] at the time of performing the measurement, and the storage unit 107. The current provisional date and time information [F] stored in is associated with and stored in the storage unit 107. At this time, a value indicating that the measurement order is "1" is assigned as the data ID [I] of the latest measurement data. For example, here, data ID [I] = 1.

[Step S305]
Next, in step S305, the valid data number counting unit 12 counts up the current valid data number [E] held in the storage unit 107 or the RAM 105 to [E] + 1. Then, the number of valid data [E] held in the storage unit 107 or the RAM 105 is rewritten to the number of valid data [E] counted up.

[Step S306]
The control unit 10 ends the measurement process in step S306.

<Structure of saved data>
FIG. 7 is a diagram for explaining an example of stored data in the biological information measuring device according to the embodiment. FIG. 7 shows an example of stored data when the biological information measuring device 100 having the above-mentioned function performs measurement eight times.

For the eight measurements, data transmission 1001 of the measurement data before that is performed before the first measurement of the data ID [I] = 8. As a result, the date and time information management procedure (No. 2) triggered by the occurrence of the data transmission event described with reference to FIG. 5 is carried out, and the current number of valid data [E] is canceled to "0". (Step S203). At this time, if the provisional date / time information [F] is "1", the date / time information management unit 11 performs a process of synchronizing the date / time information of the date / time management unit 102 with the control side date / time information of the control device 200. carry out. As a result, the date and time information management procedure (No. 1) described with reference to FIG. 4 is executed as the date and time synchronization process (step S103 = YES), and the provisional date and time information [F] is set to "0" (step S104). ).

In this state, eight measurements from data ID [I] = 8 to 1 are performed according to the procedure of the measurement process described with reference to FIG. 6, and the data ID [I] is obtained with respect to the measured value [d]. , Measurement date and time [T], and measurement data associated with provisional date and time information [F] are saved. In addition, the number of valid data [E] is counted up, and the counted up value is retained.

Then, while the measurement processing is performed eight times, the date and time information change processing 1002 and 1003 are performed twice. Among the date and time update events described with reference to FIG. 4, these change processes 1002 and 1003 are performed by (2) resetting or setting the date and time information in the operation unit 108, or (3) the biological information measuring device 100. On the other hand, the operation of inserting and removing the battery Ba is carried out. Each time these operations are performed, the tentative date / time information [F] becomes "1" (step S105), the number of valid data [E] is canceled to "0" (step S106), and the tentative date / time information [of the storage unit 107 or RAM 105]. F] and the number of valid data [E] have been rewritten.

In addition, during the eight measurement processes, a single synchronous process 1004 without data transmission is performed. That is, among the date and time update events described with reference to FIG. 4, (1) synchronization with the control side date and time information held by the control device 200 is performed. As a result, the tentative date / time information [F] becomes "0" (step S104), and the tentative date / time information [F] of the storage unit 107 or the RAM 105 is rewritten.

<Effect of biological information measuring device>
According to the biological information measuring device 100 having the configuration described above, since the measurement data is configured to generate provisional date / time information [F] indicating whether or not the measurement date / time [T] is accurate, each measurement data is used. Whether or not the constituent measurement date and time is accurate can be confirmed by the presence or absence of the provisional date and time information [F]. Moreover, when the date and time information of the date and time management unit 102 is changed for date and time information other than the synchronization process by the control side date and time information, the number of subsequent measurements can be confirmed by the number of valid data [E]. it can.

Therefore, if the measurement data is obtained by the measurement within the range of the number of valid data [E] counted from the latest measurement, it is possible to accurately correct the measurement date and time based on the accurate date and time information. As a result, even if the measurement is performed with the date and time information changed inaccurately, the measurement data obtained by those measurements may or may not be able to accurately correct the measurement date and time. It becomes possible to accurately select and manage the biometric information of the subject.

The correction processing procedure shown in this flowchart is also a part of the biometric information processing method implemented by the biometric information processing system 1, and is performed by the functions of the input / output control unit 21 and the measurement data correction unit 22 in the control device 200. .. Hereinafter, the procedure will be described by exemplifying a case where wireless communication is used as the communication unit 106 and the control side communication unit 206 with reference to the functional configuration diagram of FIG.

[Step S401]
First, in step S401, the flow of correction processing is started according to the operation in the operation unit 208. At this time, the operation unit 208 brings the communication unit 106 of the biometric information measurement device 100 close to the control side communication unit 206 of the control device 200, and starts the flow of the reception event in a state where the wireless communication is opened. Perform the operation of.

[Step S402]
After that, in step S402, the input / output control unit 21 receives n measurement data from the biometric information measuring device 100 via the control side communication unit 206. The measurement data is received from the biometric information measuring device 100 by the input / output control unit 21 sending a measurement data transmission request to the biometric information measuring device 100 according to the operation in the operation unit 208. Is carried out.

Further, the number (n) of the measurement data received here is all of the measurement data stored in the biometric information measuring device 100, or is a new measurement data that has not been previously captured in the control device 200. It's all.

[Step S403]
In step S403, the input / output control unit 21 receives the number of valid data [E] from the biometric information measuring device 100 via the control side communication unit 206. The reception of the number of valid data [E] is performed by the biometric information measuring device 100 side transmitting the measurement data and automatically transmitting the number of valid data [E].

Here, in FIG. 11A, when the measurement data of the biometric information measuring device 100 shown in FIG. 7 is transmitted from the communication unit 106 of the biometric information measuring device 100 to the control side communication unit 206 of the control device 200, The configuration of the received data taken from the input / output control unit 21 is shown. As shown in this figure, as the received data, for example, the measurement data obtained by eight measurements with the data ID [I] = 8 to 1 and the number of valid data [E] = 4 finally held. And are received.

[Step S404]
Next, in step S404, the measurement data correction unit 22 performs a process of setting the number of processes of the measurement data m to m = 1.

[Step S405]
After that, in step S405, the measurement data correction unit 22 determines whether or not the provisional date / time information [F] of the measurement data at the mth processing number is “0”. Here, according to the measurement order confirmed by the data ID [I] of the measurement data received in step S402, for example, the measurement data of the latest measurement data ID [I] = 1 is processed by the number of processes m = 1. As the measurement data to be processed first, the provisional date and time information [F] in this measurement data is confirmed.

Then, when it is determined that the provisional date / time information [F] = 0 (YES), it is determined that the date / time information of the measurement date / time is accurate, and the process proceeds to step S406. On the other hand, if it is determined that the provisional date / time information [F] = 0 (NO), the process proceeds to step S407.

[Step S407]
In step S407, the measurement data correction unit 22 determines whether or not the measurement order of the measurement data at the mth processing number is within the range of the number of valid data [E] = 4 received in step S403. Here, the measurement order is the order of measurement counted from the latest measurement. Therefore, here, it is determined whether or not the measurement data of the m-th processing number to be processed is the data obtained from the latest measurement to the fourth measurement.

Here, the measurement order, which is the order of measurement, is confirmed by the data ID [I], which is a value unique to each measurement data and is also data indicating the order in which the measurement is performed by the measurement unit 101. The measurement order may be given by the input / output control unit 21 when the measurement data is received, for example, by transmitting the measurement data in the order in which the measurement data is collected or vice versa.

As an example, the measurement data with the data ID [I] = 1 is the measurement data obtained by the latest measurement, and is the measurement data having a measurement order of 1. Further, it is determined that the measurement data of the data ID [I] = 1 to 4 is within the range of the number of valid data [E] = 4 (YES).

Then, when it is determined that the measurement order of the measurement data at the m-th processing number to be processed is within the range of the number of valid data [E] = 4 (YES), the process proceeds to step S408. On the other hand, if it is determined that the number of valid data [E] is not within the range of 4 (NO), the process proceeds to step S409.

[Step S408]
In step S408, the measurement data correction unit 22 corrects the measurement date and time [T] in the measurement data. Here, the measurement data correction unit 22 causes the input / output control unit 21 to take in the date and time information held by the biological information measuring device 100. Then, the time difference ([control side date and time information]-[date and time information]) between the captured date and time information and the control side date and time information held by the control side date and time management unit 202 of the control device 200 is calculated.

Then, as the measurement data at the m-th processing number, for example, the calculated time difference ([control side date / time information]-[date / time information]) is added to the measurement date / time [T] in the measurement data with data ID [I] = 1. The measurement date and time [T] is corrected.

After performing the above correction, the process proceeds to step S406.

[Step S409]
On the other hand, in the determination of step S407, it is determined that the measurement order of the measurement data at the m-th processing number currently being processed is not within the range of the number of valid data [E] = 4 (NO). In step S409, the measurement data correction unit 22 adds the non-correction information [A] to the measurement data at the mth processing number.

As a result, the provisional date and time information [F] = 0, the measurement date and time [T] is not accurate, and the measurement order of the measurement data is not within the range of the number of valid data [E] = 4. Uncorrectable information [A] = 1 is added to the measurement data at the mth number of execution processes for which the date and time [T] has not been corrected.

After performing the above correction, the process proceeds to step S406.

[Step S406]
In step S406, the measurement data correction unit 22 determines whether or not the processing number m of the measurement data is equal to the number of data (n) of the measurement data received in step S402, that is, whether or not m = n. To do. If it is determined that m = n (YES), the process proceeds to step S410. On the other hand, if it is determined that m = n is not (NO), the process proceeds to step S411.

[Step S410]
In step S410, the measurement data correction unit 22 stores n measurement data including the measurement data corrected by the processing of steps S405 to S409 in the storage unit 207 as correction data. Then, the process is terminated in step S412.

[Step S411]
In step S411, the measurement data correction unit 22 performs a process of setting the number of processes m to m = m + 1. Then, the process returns to step S405, and the subsequent processes are repeated until it is determined in step S406 that m = n.

FIG. 11B is a diagram showing the configuration of the measurement data corrected and stored as described above, and is a diagram showing the result of correction processing of the measurement data shown in FIG. 11A. First, as shown in FIG. 11A, among the measurement data of the data ID [I] = 1 to 8, the measurement data of the data ID [I] = 1, 2, 7, 8 is the provisional date and time information [F] =. It is 0 and the measurement date and time [T] is accurate. Therefore, the measurement date and time [T] in the corrected measurement data shown in FIG. 11B is the same date and time as before the correction.

On the other hand, as shown in FIG. 11A, the measurement data of the data ID [I] = 3 to 6 has the provisional date / time information [F] = 1 and the measurement date / time [T] is not accurate. Of these, in the measurement data of data ID [I] = 3 and 4, the data ID [I] indicating the measurement order is within the range of the number of valid data [E] = 4. On the other hand, in the measurement data of the data ID [I] = 5 and 6, the data ID [I] indicating the measurement order is out of the range of the number of valid data [E] = 4.

Therefore, as shown in FIG. 11B, the measured data of the corrected data ID [I] = 3 and 4 is a value obtained by correcting the measurement date and time [T]. On the other hand, the corrected data ID [I] = 5 and 6 are the data in which the measurement date and time [T] is not corrected and the non-correctable information [A] = 1 is added.

<Effect of biological information control device>

The measurement date and time is corrected only for the measurement data obtained by the measurement within. As a result, it is possible to carry out the correction by selecting only the date and time information that can be corrected accurately.

Further, among the measurement data having the provisional date / time information [F], the measurement data whose measurement order is outside the range of the number of valid data [E] cannot be corrected without correcting the date / time information [A] = 1. It is a configuration to add. Therefore, the correction process also clarifies the measurement data whose measurement date and time is inaccurate, and makes it possible to appropriately manage the biological information of the subject.

In this case, in the process described with reference to FIG. 11, the latest measurement (that is, data ID [I] =) in the range of data ID [I] = 3 to 6 with provisional date and time information [F] = 1. The measurement order counted from 3) is configured to perform the above-mentioned correction processing for the measurement data within the range of the number of valid data [E] = 2.
