Then, the inspection result is recorded in association with the subject information input in advance.

Japanese Unexamined Patent Publication No. 07-155300

By the way, the electrocardiogram examination in the hospital is performed by the patient going to the examination room or the examination room and using the electrocardiograph installed there. ECG examinations performed in such examination rooms and examination rooms are carried out with a relatively large amount of time.

On the other hand, an electrocardiogram may be performed in a group medical examination such as a school child medical examination. An electrocardiogram test at a school child's medical examination is carried out by bringing an electrocardiograph to the school. An electrocardiogram examination for a group, such as a schoolchildren's examination, is performed under a situation where the time is set by a timetable or the like, so the examination is often carried out in a state where there is no time to spare. Specifically, in the electrocardiographic examination performed in the examination room or the examination room, the medical staff only needs to be aware of one patient, whereas in the schoolchildren's medical examination, one class of schoolchildren are continuously examined. There is a need to continue to.

By the way, in the electrocardiogram examination, the subject information of the subject to be examined is input to the electrocardiograph (which may be called setting), and then the electrocardiogram is measured. However, since ECG examinations for groups such as schoolchildren's medical examinations may be performed in a state where there is no time to spare as described above, medical professionals are asked to the subject who is going to make measurements. There is a risk of erroneously entering subject information that is different from the corresponding subject information. Such an erroneous input may lead to a serious incident in which a measurement result of a subject different from the measurement result of the subject is associated with a certain subject.

The present invention has been made in consideration of the above points, and is a biometric information measurement capable of preventing a misunderstanding between a subject and a measurement result due to an erroneous input of subject information by a user who is a medical worker.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an external configuration of an electrocardiograph according to the present embodiment. The electrocardiograph 100 has an input key 101, a display unit 102, a printer unit 103, and the like.

FIG. 2 is a block diagram showing a configuration of a main part of the electrocardiograph 100. In addition to the input key 101, the display unit 102, and the printer unit 103, the electrocardiograph 100 is provided with a calculation unit 104, a measurement unit 105, a storage unit 106, a speaker 107, and the like.

The calculation unit 104 executes an electrocardiogram data processing program to form an electrocardiogram, analyze the electrocardiogram, and the like. Further, the calculation unit 104 includes execution start, execution stop and execution condition (threshold value, etc.) setting of the electrocardiogram data processing program, control of various measuring devices such as the measurement unit 105, and various types of the display unit 102, the printer unit 103, the speaker 107, and the like. Peripheral device control is performed according to the input command.

The measuring unit 105 is connected to an electrode unit mounted on the subject, performs amplification processing or the like on the measured voltage input from the electrode unit, and outputs the processed measured voltage to the calculation unit 104. Incidentally, the limb electrode portion and the chest electrode portion are usually connected to the measuring unit 105, and the voltage required to obtain a standard 12-lead electrocardiogram (hereinafter, simply referred to as “12-lead electrocardiogram”) is input. To.

The storage unit 106 is composed of a hard disk drive, a semiconductor memory, or the like. The storage unit 106 stores the electrocardiogram data obtained by the calculation unit 104 and the analysis data thereof. The storage unit 106 also stores the measurement data output from the measurement unit 105.

A menu screen and various setting screens are displayed on the display unit 102. Further, the display unit 102 displays the electrocardiogram and the analysis result obtained by the calculation unit 104. In the present embodiment, the display unit 102 has a touch panel configuration, and a user who is a medical worker (hereinafter, simply referred to as “user”) can select a menu or perform various operations by touching the display unit 102. You can enter. That is, the electrocardiograph 100 can also perform input using the display unit 102 in addition to input using the input key 101.

The printer unit 103 is a printer of a laser type or a thermal head type, and prints an electrocardiogram and an analysis result obtained by the calculation unit 104 according to a user's instruction.

FIG. 3 is a flowchart for explaining the characteristic operation of the electrocardiograph 100 of the present embodiment. The flowchart of FIG. 3 is executed when the electrocardiograph 100 is used for a group medical examination such as a school child medical examination.

The electrocardiograph 100 first measures the electrocardiogram of the subject A in step S11, and then interrupts or ends the measurement in step S12. The measurement is interrupted or terminated by the user operating the interrupt button or the end button included in the input key 101.

In the following step S13, the electrocardiograph 100 measures the electrocardiogram when the start button included in the input key 101 is operated by the user.

The electrocardiograph 100 proceeds to step S14 during the measurement of the electrocardiogram in step S13 or when the measurement is completed, and determines whether or not the electrocardiograms are the same. Specifically, the calculation unit 104 obtains the similarity between the electrocardiogram measured in step S11 stored in the storage unit 106 and the electrocardiogram measured in step S13, and the electrocardiogram is the same based on this similarity. Judge whether or not. The method of determining this identity will be described in detail later.

When the electrocardiograph 100 determines in step S14 that the electrocardiograms are the same, the electrocardiograph 100 proceeds to step S15 to determine whether or not the subject information has been changed. Specifically, the calculation unit 104 stores the subject information associated with the electrocardiogram measured in step S11 and the subject information associated with the electrocardiogram measured in step S13. By comparing with the person information, it is judged whether or not the subject information has been changed. If there is no change in the subject information, it is determined that the normal input operation of the subject information has been performed by moving from step S15 to step S16. On the other hand, when there is a change in the subject information, the process proceeds from step S15 to step S17 to output an alarm. Specifically, in step S17, the electrocardiograph 100 displays an alarm such as "The subject information is incorrect. Please enter the correct subject information." On the display unit 102. A voice prompting the correction of the subject information is output from the speaker 107.

As described above, in the electrocardiograph 100, when the electrocardiogram measured last time and the electrocardiogram measured this time are the same, but the subject information is different between the time of the previous measurement and the time of the current measurement, the subject is covered. Notify the user with an alarm that the examiner information is incorrect.

On the other hand, if the electrocardiograph 100 determines in step S14 that the electrocardiograms are not the same, the process proceeds to step S18. The electrocardiograph 100 determines whether or not the subject information has changed in step S18, and if the subject information has changed, the electrocardiograph 100 moves from step S18 to step S19 to input normal subject information. Is determined to have been done. On the other hand, if there is no change in the subject information, the process proceeds from step S18 to step S20 to output an alarm. The alarm output is the same as in step S17.

As described above, in the electrocardiograph 100, when the subject information is the same between the previous measurement and the current measurement even though the electrocardiogram measured last time and the electrocardiogram measured this time are different, the subject Notify the user with an alarm that the information is incorrect.

In fact, in a group medical examination such as a schoolchildren's medical examination, when the electrocardiogram measurement is completed in step S12, the subject information of the next subject is input by the user before the electrocardiogram measurement in step S13 is started. Will be done. On the other hand, when the electrocardiogram measurement is interrupted in step S12, the electrocardiogram of the same subject is continuously measured in step S13, so that the user inputs the subject information of the next subject. (In other words, do not enter the subject information of the next subject).

Specifically, in schoolchildren's medical examinations, the grade, group, and attendance number are used as subject information, and the attendance numbers are added to perform continuous electrocardiographic examinations in many cases. Here, if the inspection can be performed without any problem (that is, if the measurement is completed in step S12), the user can operate the "Next" operation button included in the input key 101 to obtain one attendance number of the subject information. After raising it, the process proceeds to step S13 to measure the next child. On the other hand, the electrocardiogram measurement may be repeated after the measurement in step S11. In this case, the process proceeds to step S13 without increasing the attendance number, and the same child is measured again.

However, at this time, the user may mistakenly increase the attendance number by one to perform the measurement. If the attendance number is increased by one even though the measurement is redone, the stored measurement data (electrocardiogram) is one before the attendance number even though the attendance number is the next child. It belongs to the child. That is, the subject and the electrocardiogram are erroneously linked.

In this way, in the group medical examination, there is not enough time or there is no acquaintance between the user and the subject, so the user should enter the subject information of the next subject, but enter it. Forgetting to do so, the next ECG measurement may be performed with the previous subject information, or new subject information may be entered even though the next subject's subject information should not be entered. As a result, there is a risk that the subject and the electrocardiogram will be erroneously linked.

In the electrocardiograph 100 of the present embodiment, as described above, the identity between the previous measurement result and the current measurement result is determined, and the subject information of the previous measurement and the subject information of the current measurement are used. By determining the identity of the subject, determining the incorrect input of the subject information based on the identity of the measurement result and the identity of the subject information, and outputting an alarm, the user is erroneously input. Can be made to recognize and prompt the input of correct subject information.

In short, the electrocardiograph 100 of the present embodiment is an input for inputting subject information of a subject whose biological information is measured by a biological information measuring unit (calculation unit 104, measuring unit 105) and a biological information measuring unit. The unit (input key 101) determines the identity between the biometric information at the time of the previous measurement and the biometric information at the time of the current measurement by the biometric information measurement unit, and the subject information at the time of the previous measurement and the subject at the time of the current measurement. Judgment unit (calculation unit 104) that determines the identity with the person information and determines the validity of the input subject information based on these identities, and presents the judgment result by the judgment unit to the user. It has a presentation unit (display unit 102, speaker 107).

Next, the process of determining the identity of the electrocardiogram performed in step S14 will be described.

Here, an example of determining the identity of the electrocardiogram using the limb-guided electrocardiogram (I, II, III, aVR, aVL, aVF) is shown. As shown in FIG. 4, P wave, Q wave, R wave, S wave, and T wave appear on the electrocardiogram. The P wave indicates the excitatory process of the atrium, the QRS complex indicates the excitement of both the left and right ventricles, and the T wave indicates the repolarization of the ventricular muscle. In this embodiment, the PR interval [seconds], QRS interval [seconds], QT interval [seconds], and / or QRS axis [°] are used to determine the identity of the electrocardiogram. The judgment may be made using all of these four parameters, or the judgment may be made using any one or more of them. Of course, the more parameters used for judgment, the higher the accuracy of judgment. The calculation unit 104 determines whether or not the subject has the same ECG based on how similar these parameters are in the previous ECG and the current ECG.

Since the height of the waveform of the electrocardiogram varies greatly depending on the position where the electrodes are attached, the height of the waveform is not used in this embodiment, but the time interval is used for the determination. However, if it is the ratio of the height of the waveform, it is considered that the fluctuation of the height of the waveform due to the change of the electrode attachment position can be ignored, so the ratio of the height of the previous electrocardiogram and the height of the current electrocardiogram is used. You may do so. As described above, when determining the identity (similarity), it is important to use a parameter that is less affected by the electrode attachment position.

Further, in order to reduce the influence of the heart rate in the excited state and the sedated state, for example, the ratio of the PR interval and the RT interval may be used for the determination.

As described above, according to the present embodiment, the identity between the electrocardiogram measured last time and the electrocardiogram measured this time is determined, and the subject information at the time of the previous measurement and the subject at the time of this measurement are determined. Judging the identity with the information, judging the validity of the subject information based on the identity of the electrocardiogram and the identity of the subject information, and presenting the judgment result of the validity to the user. Therefore, it is possible to realize an electrocardiograph 100 capable of preventing a misunderstanding between a subject and a measurement result due to an erroneous input of subject information by a user.

In particular, in group medical examinations such as schoolchildren's medical examinations, in most cases there is no acquaintance between the user and the subject, and the link between the measurement result and the subject is left only to the operation of the input key 101 by the user. The operation of the input key 101 is also performed in a short time, and it is easy for the subject information to be erroneously input. Further, the method of inputting the subject information is such that the subject information is sequentially switched according to the number of times the operation button is pressed, and erroneous input is more likely to occur. Under such circumstances, the configuration of this embodiment is very effective.

The above-described embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be construed in a limited manner by these. That is, the present invention can be implemented in various forms without departing from its gist or its main features.

In the above-described embodiment, the case where the alarm is output when the erroneous input of the subject information is detected has been described, but the present invention is not limited to this, and instead of outputting the alarm or outputting the alarm. In addition, the degree of similarity between the previous measurement result and the current measurement result may be calculated and displayed. Even in this way, it is possible to make the user recognize the erroneous input and prompt the user to input the correct subject information.

Further, in the above-described embodiment, the case where the subject information can be sequentially switched depending on the number of times the operation button (“Next” operation button) is pressed has been described, but of course, the subject information is input. The method is not limited to this. For example, the subject ID may be input.

Further, in the above-described embodiment, the case where the present invention is applied to an electrocardiograph has been described, but the present invention is not limited to this, and the above-mentioned implementation is also performed when the present invention is applied to a biometric information measuring device other than the electrocardiograph. The same effect as the form of can be obtained. The present invention is, in essence, a biological information measuring unit, an input unit for inputting subject information of a subject who measures biological information by the biological information measuring unit, and biological information at the time of the previous measurement by the biological information measuring unit. While judging the identity with the biological information at the time of this measurement, the identity between the subject information at the time of the previous measurement and the subject information at the time of this measurement is judged, and it is input based on these identities. It suffices to have a judgment unit for judging the validity of the subject information and a presentation unit for presenting the judgment result by the judgment unit to the user. In the above-described embodiment, the identity of the biometric information is determined based on the electrocardiogram, but the identity of the biometric information may be determined based on the measured numerical value of the biometric information or a waveform other than the electrocardiogram. For example, the identity of the biological information may be determined based on the biological information such as heart rate, blood pressure, and SPO ₂ .

At this time, the biological information measured by the biological information measuring unit is not necessarily limited to one type, and may be a plurality of types. In this case, the identity of the biometric information is determined using a plurality of types of biometric information. The identity of the biometric information means the identity between all the biometric information at the time of the previous measurement and all the biometric information at the time of the current measurement, and the identity is determined by comprehensively using a plurality of biometric information. To. For example, for each type of biometric information, the points of identity between the biometric information at the time of the previous measurement and the biometric information at the time of the current measurement are calculated, the points of identity are added for multiple types of biometric information, and based on the added points. The identity of the biometric information at the time of the previous measurement and the time of the current measurement may be obtained.

The present invention is suitable for an electrocardiograph used for a group medical examination such as a school child medical examination.
