The number of days for monitoring the electrocardiogram by wearing the portable electrocardiograph 2 can be appropriately determined according to the above-mentioned purpose of use, but as a guide, it is 1 to 10 days, more preferably 2 to 7 days.

The portable electrocardiograph 2 can be attached to the subject's chest via a gel pad. The mounting position of the portable electrocardiograph 2 can be specified based on the instructions of the medical staff according to the required waveform, but from the viewpoint of reducing the influence of noise and myoelectricity, it is mounted in the center of the chest. Is preferable. In this case, the direction of the portable electrocardiograph 2 is more preferably such that the longitudinal direction of the main body is perpendicular to the ground.

The portable electrocardiograph 2 acquires an electrocardiogram signal (electrocardiogram information) by an input unit, a conversion unit converts this analog signal into digital data (electrocardiogram data), and a storage unit stores this. Then, the obtained electrocardiogram data is transmitted to the transmission processing terminal 3 via the wireless transmission unit or the connection unit.

The biological information acquired by the portable electrocardiograph 2 is not necessarily limited to the electrocardiogram data, and may be configured to acquire other biological information such as body surface temperature, if desired.

As shown in FIG. 2, the transmission processing terminal 3 includes a data storage means 31, a round slice data conversion means 32, a round slice data storage means 321, a data transmission means 33, a transmission success data deletion means 34, and a re-execution means. 35 and. The functions of the transmission processing terminal 3 described below are also applicable to the description of the transmission processing program of the present invention.

Further, the transmission processing terminal 3 of the present invention may be further provided with a marking means for recording the time, symptom, etc. when the subject becomes aware of the irregular pulsation during the measurement period of the electrocardiogram data.

The transmission processing terminal 3 may be configured to have a data communication function, and a smartphone terminal or a tablet terminal can be adopted. Further, these terminals include a computing device (CPU (Central Processing Unit)) and a main storage device (RAM (Random Access Memory)) as a working memory as hardware components.

The data storage means 31 is configured to temporarily store continuous electrocardiogram data transmitted from the portable electrocardiograph 2. The round slice data conversion means 32 is configured to convert the stored electrocardiogram data into electrocardiogram data for each predetermined unit time.

The above-mentioned "predetermined unit time" is preferably in units of 1 minute to 6 hours, more preferably in units of 1 minute to 3 hours, more preferably in units of 5 to 60 minutes, still more preferably in units of 5 to 45 minutes, and particularly preferably in units of 5 to 45 minutes. It is in units of 5 to 30 minutes.
By setting the predetermined unit time as described above, the viewability and manageability of data are improved.

In a preferred embodiment of the present invention, the electrocardiogram data converted as data for each predetermined unit time by the round slice data conversion means 32 is stored in the transmission processing terminal 3 by the round slice data storage means 321, and the server 4 is stored by the data transmission means 33. Will be sent to.

Further, in another embodiment of the present invention, the portable electrocardiograph 2 may be configured to generate electrocardiogram data for each predetermined unit time. In this case, the electrocardiogram data is stored by the round slice data storage means 321 and transmitted to the server 4 by the data transmission means 33.

Further, in a preferred embodiment of the present invention, the data transmission means 33 automatically transmits the electrocardiogram data for each predetermined unit time stored in the round slice data storage means 321 every time the predetermined unit time elapses. Send to.

With such a configuration, for example, when the predetermined unit time is set to 15 minutes, the medical staff can monitor the electrocardiogram data of the subject every 15 minutes, that is, in substantially real time. it can.

Further, even when the monitoring is not performed in substantially real time, that is, when the diagnosis is performed at a later date and time, all the electrocardiogram data of the subject measured during the observation period are accumulated in the server 4 as data in units of 15 minutes. Therefore, the medical staff can quickly and easily access the desired data.

Further, the present invention is a data storage means which includes the above-mentioned data transmission means 33, but stores the electrocardiogram data stored in the round slice data storage means 321 for each predetermined unit time without automatically transmitting the electrocardiogram data to the server 4. It can also be configured to include. In this case, the electrocardiogram data stored in the round slice data storage means 321 is stored in the transmission processing terminal 3 without being deleted by the transmission success data deletion means 34 described later. The accumulated electrocardiogram data can be viewed as electrocardiogram data for each predetermined unit time through the display unit of the transmission processing terminal 3.

With such a configuration, the present invention can be applied even when, for example, the transmission processing terminal 3 and the server 4 are not in a communicable environment. The electrocardiogram data stored in the data storage means is configured to be transmitted to the server 4 by the manual transmission means that manually transmits the electrocardiogram data to the server 4 when the transmission processing terminal 3 and the server 4 can communicate with each other. You can also do it.

Further, the present invention provides the above-mentioned data transmitting means 33, but does not convert the continuous electrocardiogram data transmitted from the portable electrocardiograph 2 into the electrocardiogram data at predetermined unit times, but instead sends the continuous electrocardiogram data to the server 4. It can also be configured to include a real-time transmission means for transmission.

With such a configuration, it is possible to monitor ECG data in real time for a subject who requires intensive management or observation.

As described above, the present invention further includes not only the data transmission means 33 that automatically transmits the electrocardiogram data for each predetermined unit time to the server 4, but also the data storage means, the manual transmission means, and the real-time transmission means. it can. Therefore, the target person or the medical worker can appropriately select the transmission mode of the electrocardiogram data according to the purpose.

Each of these functions can be switched by the target person himself or a related person such as the target person's family by changing the setting of the transmission processing terminal 3.

The transmission success data deletion means 34 automatically deletes the electrocardiogram data for which the transmission was successful when the electrocardiogram data stored in the round slice data storage means 321 for each predetermined unit time is successfully transmitted to the server 4. It is a configuration to do.

When the transmission success data deletion means 34 receives a notification indicating that the server 4 has succeeded in normally receiving the electrocardiogram data from the notification means 43 described later, it determines that the transmission of the electrocardiogram data has been successful, and the transmission is successful. It is preferable that the data is deleted from the transmission processing terminal 3.

More specifically, in the transmission success data deleting means 34, after the electrocardiogram data is transmitted to the server 4 by the data transmitting means 33 and a certain time has elapsed after the receiving means 41 described later receives the electrocardiogram data. Upon receiving the notification, it is determined that the transmission of the electrocardiogram data has been successfully completed, and the transmission success data is deleted from the transmission processing terminal 3. The above-mentioned "constant time" will be described later.

Further, as will be described later, whether the notification means 43 has successfully completed the transmission of the received electrocardiogram data to the server 4 depending on whether or not the received electrocardiogram data is stored in the server 4 by the storage means 42 within a certain time. It can be determined whether or not.

When the re-execution means 35 fails to transmit the electrocardiogram data stored in the round slice data storage means 321 for each predetermined unit time to the server 4, the re-execution means 35 automatically transmits the electrocardiogram data for which the transmission fails after the elapse of the predetermined time. This is a configuration for retransmitting to the server 4.

When the re-execution means 35 receives a notification indicating that the server 4 has failed to normally receive the electrocardiogram data from the notification means 43 described later, the re-execution means 35 determines that the transmission of the electrocardiogram data has failed, and receives the notification. It is preferable to perform the transmission process again after a lapse of a predetermined time.

More specifically, in the re-execution means 35, the electrocardiogram data is transmitted to the server 4 by the data transmission means 33, and the notification means is notified after a certain time has elapsed since the receiving means 41 described later receives the electrocardiogram data. When the notification that the transmission has failed is received from 43, it is determined that the transmission of the electrocardiogram data has failed, and after a predetermined time has elapsed, the transmission failure data is retransmitted.

The predetermined time can be arbitrarily set, but within a predetermined unit time, which is a unit for rounding the electrocardiogram data, preferably once or more, more preferably two times or more, still more preferably three times or more, again. It is preferable to set the time during which the transmission process of

More specifically, the predetermined time is preferably 1 to 100 minutes, more preferably 3 to 60 minutes, still more preferably 5 to 30 minutes, and particularly preferably 5 to 15 minutes. More specifically, when the electrocardiogram data for each predetermined unit time is set as the data for each 15 minutes, the predetermined time is preferably 5 minutes.

With such a configuration, even if a certain 15-minute unit ECG data fails to be transmitted to the server 4, the transmission is performed by the time the next 15-minute unit ECG data is accumulated in the transmission processing terminal 3. You will have the opportunity to resend the failed data three times.

Therefore, by removing the factor that caused the transmission failure during this period, it is possible to prevent the ECG data in units of 15 minutes from being excessively accumulated in the transmission processing terminal 3, and the transmission efficiency to the server 4 can be improved. improves.
From such a viewpoint, it is preferable to set the predetermined time to a time during which the transmission process can be performed again at least the above number of times.

Further, the re-execution means 35 repeatedly executes the transmission process until the transmission of the transmission failure data to the server 4 is successful. In a preferred embodiment, when the re-execution means 35 fails to transmit the re-executed electrocardiogram data to the server 4, the re-execution means 35 re-executes the transmission of the transmission failure data to the server 4 after the elapse of the predetermined time. , The transmission process is repeated until the transmission of the transmission failure data to the server is successful.
Then, similarly to the above, the re-execution means 35 succeeds in receiving the notification of whether or not the server 4 has succeeded in normally receiving the electrocardiogram data from the notification means 43, which will be described later, by the re-transmission process. Determine if the data transmission is complete. Then, when the notification means 43 notifies that the transmission has failed, the re-execution means 35 performs the transmission process again after the same time as the predetermined time has elapsed.

Summarizing the above, it is preferable to have a configuration in which transmission processing in the following flow is realized.
(I) Transmission of electrocardiogram data to server 4 fails (ii) Re-execution means 35 retransmits after a predetermined time (iii) Re-transmission by re-execution means 35 also fails (iv) Re-execution means 35 fails for a predetermined time (V) Repeat (iii) and (iv) until the transmission is successful.

When the above-mentioned unit time is Ta (minutes), the above-mentioned predetermined time is Tb (minutes), and the number of times that the transmission process can be performed again within the unit time is n (times), the following formula is established.
(Equation 1) Ta ≧ Tb · n

In formula 1, n is 1 or more, more preferably 2 or more, and even more preferably 3 or more.
Further, in the formula 1, Ta is preferably 1 minute to 6 hours, more preferably 1 minute to 3 hours, more preferably 5 to 60 minutes, still more preferably 5 to 45 minutes, and particularly preferably 5 to 30 minutes.
The Tb is preferably 1 to 100 minutes, more preferably 3 to 60 minutes, still more preferably 5 to 30 minutes, and particularly preferably 5 to 15 minutes.

On the other hand, when the notification means 43 described later notifies that the transmission is successful, the re-execution means 35 ends the repeated transmission process. Then, the transmission success data deleting means 34 deletes the electrocardiogram data from the transmission processing terminal 3.

When the transmission failure of the electrocardiogram data to the server 4 by the re-execution means 35 lasts for a certain long time, the electrocardiogram data for each predetermined unit time following the transmission failure data is stored in the server in the transmission processing terminal 3. It will be accumulated without being transmitted to 4.

Even in such a case, in order to improve the transmission efficiency of the electrocardiogram data, the re-execution means 35 together with the electrocardiogram data related to the transmission failure, the electrocardiogram data accumulated until the transmission failure data to the server 4 is successful. It is preferable that the data is also transmitted to the server 4.

For example, in the case where the electrocardiogram data for each predetermined unit time is set to the electrocardiogram data for each 15 minutes, when the predetermined time until the re-transmission processing is performed again by the re-execution means 35 is set to 5 minutes, the re-transmission processing is performed. If all three failures occur, the next 15-minute unit electrocardiogram data is accumulated in the transmission processing terminal 3. In such a case, the transmission efficiency of the electrocardiogram data is improved by configuring the configuration in which the next 15 units of electrocardiogram data are transmitted to the server 4 together with the transmission failure data.

It is more preferable that the transmission processing terminal 3 is provided with DICOM conversion means for converting ECG data into DICOM format data.

Conventionally, images related to inspections by radiation equipment such as CT (Computed Tomography), CR (Computed Radiography), MR (Magnetic Resonance), and XA (X-Ray Angiography) are managed by DICOM servers in the facility as DICOM format data. It was common to be done.

On the other hand, one-dimensional waveform data related to physiological tests such as electrocardiogram, electroencephalogram, and respiratory waveform are stored in a data format different from DICOM format, and are managed differently from DICOM data even within the same facility. It was.

Therefore, by converting the electrocardiogram data according to the present invention into DICOM format data, the electrocardiogram data of the subject can be centrally managed by the DICOM server together with other medical data.

Note that converting ECG data into DICOM format data is not necessarily limited to the transmission processing terminal 3. The server 4, which will be described later, may have the same function.

Next, the server 4 will be described. The server 4 includes a receiving means 41, a storage means 42, a notification means 43, a transmitting means 44, and an analysis means 45.

The receiving means 41 is configured to receive the electrocardiogram data transmitted from the transmission processing terminal 3. Then, after the receiving means 41 receives the electrocardiogram data of the target person, the storage means 42 stores the electrocardiogram data in the server 4.

Furthermore, the medical staff can press the "Automatic data acquisition for the last 2 days" button located on the left side of the upper part of the figure to measure the data for the last 2 days with all the portable electrocardiographs 2 registered in the facility. It is also possible to check the electrocardiogram data at predetermined unit times and automatically download the unacquired data.

The above-mentioned ECG data download is an embodiment in which the server 4 and the viewing terminal 5 are communicably connected via the network NW, and the present invention has such an embodiment. While assuming the form, it is also possible to download the electrocardiogram data offline.

In this case, the transmission processing terminal 3 and the viewing terminal 5 are connected by a Lightning cable or the like, and the electrocardiogram data stored in the round slice data storage means 321 of the transmission processing terminal 3 is duplicated in the viewing terminal 5. The electrocardiogram data duplicated on the viewing terminal 5 can be manually deleted from the transmission processing terminal 3.

The medical worker can browse the electrocardiogram data acquired in this way through the browsing terminal 5 and diagnose the presence or absence of an arrhythmia event in the subject by himself / herself.

In addition, the medical staff specifies the electrocardiogram data measured by a specific portable electrocardiograph 2 in a specific time zone, requests an external specialist to analyze it, and refers to the result of the analysis. It is also possible to diagnose the subject.

The analysis means 45 is configured to analyze the electrocardiogram data on the server 4 in response to a request from the viewing terminal 5. The medical worker can access the dedicated website from the browsing terminal 5 via a web browser and browse the electrocardiogram data stored in the server 4.

On the website, all the electrocardiogram data measured by the portable electrocardiograph 2 registered in the facility can be displayed in the same way that the browsing terminal 5 displays via a dedicated program. Therefore, the medical staff can browse arbitrary electrocardiogram data on the website without downloading to the browsing terminal 5 of the facility by the dedicated program.

The analysis means 45 automatically detects the presence or absence of an arrhythmia event in the electrocardiogram data designated by the medical staff. The type of arrhythmia to be detected is not particularly limited, but diagnostic names include, for example, atrial fibrillation, ventricular tachycardia, ventricular fibrillation, paroxysmal supraventricular tachycardia, extrasystole, sinus tachycardia, and atrioventricular. Block, sinus dysfunction syndrome, etc. can be mentioned.

The automatic analysis of the presence or absence of an arrhythmia event can be executed by designing an algorithm according to the type of arrhythmia to be detected. Such an algorithm can have the same configuration as that conventionally installed and used in an information processing terminal such as a PC as an electrocardiogram automatic analysis program.

As described above, according to the present invention, the analysis means 45 makes it possible to browse all the electrocardiogram data of the subject, preferably on the cloud server, and further automatically analyze the arbitrary electrocardiogram data to improve the work efficiency of the medical staff. Not only will it improve, but it will also enable diagnostic support.

FIG. 4 is a flowchart showing the flow of processing in the electrocardiogram monitoring system 1 of the present embodiment from the portable electrocardiograph 2 to transmitting the electrocardiogram data to the server 4 via the transmission processing terminal 3.

In FIG. 4, in step S1, the portable electrocardiograph 2 acquires the electrocardiogram data of the subject and transmits it to the transmission processing terminal 3. Then, in the following step S2, the data storage means 31 stores the electrocardiogram data transmitted from the portable electrocardiograph 2.

The electrocardiogram data stored here is converted into electrocardiogram data for each predetermined unit time by the round slice data conversion means 32, and then stored in the transmission processing terminal 3 by the round slice data storage means 321 (step S3).

As step S4, the electrocardiogram data for each predetermined unit time is transmitted to the server 4 by the data transmitting means 33, and the receiving means 41 accepts this. As a result, the electrocardiogram data successfully transmitted to the server 4 is automatically deleted from the transmission processing terminal 3 by the transmission success data deleting means 34 (step S5).

On the other hand, the electrocardiogram data that has failed to be transmitted to the server 4 is repeatedly transmitted to the server 4 by the re-execution means 35 until the transmission to the server 4 is successful after a lapse of a predetermined time (step S6). ). The electrocardiogram data successfully transmitted to the server 4 by the re-execution means 35 is deleted from the transmission processing terminal 3 by the transmission success data deleting means 34.

FIG. 5 is a flowchart showing a processing flow from the transmission of the electrocardiogram data from the transmission processing terminal 3 to the server 4 in step S4 in FIG. 4 until the server 4 determines the success or failure of the transmission of the electrocardiogram data. ..

In step S41, the receiving means 41 of the server 4 receives the electrocardiogram data transmitted from the transmission processing terminal 3. Then, in step S42, the storage means 42 executes the storage process of the electrocardiogram data in the server 4.

The notification means 43 determines whether or not the electrocardiogram data has been successfully transmitted to the server 4 depending on whether or not the electrocardiogram data is stored in the server 4 by the storage means 42 within a certain time.

As a result, when the storage process is completed within a certain time, the notification means 43 determines that the normal reception of the electrocardiogram data has been completed, and retains the stored electrocardiogram data in the server 4. Then, as step S43, the notification means 43 notifies the transmission processing terminal 3 that the transmission of the electrocardiogram data has been successful. On the other hand, if the storage process is not completed within a certain time, the notification means 43 notifies the transmission processing terminal 3 that the transmission of the electrocardiogram data has failed.

When the transmission of the electrocardiogram data fails, the re-execution means 35 of the transmission processing terminal 3 executes the re-transmission processing of the electrocardiogram data whose transmission has failed after a predetermined time has elapsed from the notification, and the receiving means 41 , The electrocardiogram data reception process is performed again (step S41). When the transmission fails, the series of processes is repeatedly executed until the transmission of the electrocardiogram data is successfully completed.
