Description

  The present invention particularly relates to an electrocardiogram measuring apparatus and an electrocardiogram measuring system capable of measuring a daily electrocardiogram when necessary.

  Conventionally, a belt-like electrocardiogram measuring apparatus that continuously measures an electrocardiogram in daily life like a Holter electrocardiograph has been proposed (for example, Patent Documents 1 and 2). In this electrocardiogram measuring apparatus, a bioelectrode is provided on a belt, and the electrocardiogram is measured by winding the belt directly around a chest or the like.

In addition, an event electrocardiograph that is carried so that an electrocardiogram can be measured by itself when some symptom such as arrhythmia is felt has been proposed (for example, Patent Document 3). The electrocardiogram measuring apparatus disclosed in Patent Document 3 is formed in a pen shape so as to be portable.
Japanese Utility Model No. 6-1685 JP 2002-143110 A Japanese Patent Laid-Open No. 10-234689

  However, for a subject who develops symptoms about once every few days to several weeks, even if the electrocardiogram is continuously measured with a Holter electrocardiograph, the time for which the electrocardiogram can be measured is limited to about 24 hours. Therefore, it is often impossible to measure the arrhythmia necessary for diagnosis. In addition, a pen-type electrocardiogram measuring apparatus as disclosed in Patent Document 3 tends to forget to be worn or carried. Also, when you feel any symptom, it takes some time to take out the pen-type ECG measurement device and measure the ECG, and it may not be enough to measure the ECG when you feel any symptom. .

  Therefore, an object of the present invention is to provide an electrocardiogram measuring apparatus capable of reliably measuring an electrocardiogram when necessary over a long period of time and an electrocardiogram measurement system using the same.

  An electrocardiogram measuring apparatus according to the present invention includes a bioelectrode attached to a clothing accessory, an electrocardiogram recognition unit that recognizes an electrocardiogram at a potential detected by the bioelectrode, a memory for storing the electrocardiogram, and an electrocardiogram recognition unit. And a processing unit for storing the electrocardiogram in a memory when it is recognized.

  According to this electrocardiogram measuring apparatus, since the biological electrode is attached to the accessory, if the accessory is worn, the user will not forget to carry it. Further, when any symptom is felt, there is no need to search for an electrocardiogram measuring device, and the measurement of the electrocardiogram can be started immediately by simply touching the biological electrode of the wearing accessory, and the electrocardiogram can be measured reliably. That is, by touching the bioelectrode, the electrocardiogram recognition unit recognizes the potential detected by the bioelectrode as an electrocardiogram, and the electrocardiogram measured by the processing unit is stored in the memory. Moreover, since the measurement is performed only when the electrocardiogram needs to be measured, the electrocardiogram can be measured and stored for a long period of time even if the memory capacity is not large.

  In the above electrocardiogram measurement apparatus, the accessory is preferably a belt. The belt is passed through belt loops such as trousers and skirts so that the trousers and skirts do not fall off. Then, when any symptom is felt, the electrocardiogram can be measured immediately by touching the bioelectrode attached to the belt immediately.

  Further, the electrocardiogram measuring apparatus further includes a mode setting unit for setting an event electrocardiogram measurement mode for measuring an event electrocardiogram or an electrocardiogram continuous measurement mode for continuously measuring an electrocardiogram, and the mode setting unit is set to the event electrocardiogram measurement mode. When the electrocardiogram is recognized by the electrocardiogram recognition unit, the processing unit stores the electrocardiogram in a memory, and when the mode setting unit is set to the electrocardiogram continuous measurement mode, the processing unit Preferably, the potential detected by the electrodes is continuously stored in the memory. According to this electrocardiogram measuring apparatus, when measuring an electrocardiogram at the time of an event, that is, when any symptom appears, the mode setting unit sets the event electrocardiogram measurement mode so that the bioelectrode does not directly touch the surface of the living body. To wear. Thereby, when the subject feels some symptom, the electrocardiogram is recognized by the electrocardiogram recognition unit by touching the bioelectrode, and the measured electrocardiogram is stored in the memory by the processing unit. On the other hand, when it is desired to continuously measure the biological signal, the mode setting unit sets the electrocardiogram continuous measurement mode and wears the accessory so that the biological electrode is directly touched on the surface of the biological body. Thereby, regardless of whether or not the subject feels any symptom, the processing unit can continuously store the potential detected by the biological electrode in the memory. In addition, a mode suitable for the subject can be selected from the event electrocardiogram measurement mode and the electrocardiogram continuous measurement mode according to the symptom of the subject, the frequency at which the symptom appears, and the like.

  Alternatively, the electrocardiogram measurement apparatus described above includes, as biological electrodes, a first biological electrode and a second biological electrode that are attached to a biological surface, and a third biological electrode that is attached to a jewelry so as not to contact the biological surface. The electrocardiogram recognition unit recognizes the electrocardiogram at a potential detected by the first bioelectrode or the second bioelectrode and the third bioelectrode, and the processing unit recognizes the first bioelectrode and the first bioelectrode The electrocardiogram measured by the two bioelectrodes is stored in the memory, and measured by the first bioelectrode or the second bioelectrode and the third bioelectrode when the electrocardiogram is recognized by the electrocardiogram recognition unit. The stored ECG data may be stored in a memory. The subject wears an electrocardiogram measurement device and touches the third biological electrode with his / her hand when he / she feels any symptoms. Then, the electrocardiogram recognition unit recognizes the electrocardiogram based on the potential detected by the first biological electrode or the second biological electrode and the third biological electrode. Therefore, the processing unit stores electrocardiogram data measured by the first biological electrode or the second biological electrode and the third biological electrode when the subject feels some symptom (at the time of an event) in the memory. It can be memorized. Moreover, since the electrocardiogram data is continuously measured and stored by the first bioelectrode and the second bioelectrode, the electrocardiogram data before the subject feels any symptoms (pre-event) should also be confirmed. Can do.

The processing unit includes the first bioelectrode and the second bioelectrode. The electrocardiogram data measured by the biological electrode of the first biological electrode or the second biological electrode when the depression of the third biological electrode is detected by the pressing detection means; Electrocardiogram data measured by the third biological electrode is stored in a memory.

  When the subject wears this electrocardiogram measurement device and feels some symptom, he / she presses the third bioelectrode by hand and keeps touching the third bioelectrode. Then, the pressing detection unit detects that the third biological electrode has been pressed. Thereby, the processing unit stores the electrocardiogram data measured by the first bioelectrode or the second bioelectrode and the third bioelectrode when the subject feels some symptom (at the time of the event). Can be memorized. In addition, since the electrocardiogram data is continuously measured and stored by the first and second bioelectrodes mounted on the surface of the living body, before the subject feels any symptoms (pre-event ) ECG data can also be confirmed. Here, the third biological electrode also serves as a switch for starting recording of electrocardiogram data measured by the first biological electrode or the second biological electrode at the time of the event and the third biological electrode. Therefore, the electrocardiogram measurement apparatus is configured more efficiently than the case where a switch for starting recording of electrocardiogram data and a bioelectrode are separately provided. Also, it is not necessary for the subject to press or touch the switch and the third biological electrode. Furthermore, even when the subject unintentionally touches the third biological electrode, the measurement of the electrocardiogram data can be prevented, and the third biological electrode is intentionally pressed by the hand. In such a case, the electrocardiogram data can be measured.

If the electrocardiogram is not recognized (NO), the determination is continued until the electrocardiogram is recognized.

  In S102, when the subject A feels some symptom and touches each of the bioelectrodes 4 and 4 with both hands, the electrocardiogram recognition unit 23 recognizes the electrocardiogram (YES), while the electrocardiogram data is recognized, the processing unit 11 stores the electrocardiogram data in the loop memory 12 together with the current time data output from the clock 13 and the triaxial acceleration data output from the triaxial acceleration sensor 17 (S103). Then, the processing unit 11 determines whether or not the amount of data stored in the loop memory 12 has reached the set data length of the loop memory 12 (S104), and while it has not reached the set data length (NO) , The process returns to S103 and various data are continuously stored in the loop memory 12. The set data length is set within a data amount for one cycle in the loop memory 12 for each parameter.

  In S104, when the data amount reaches the set data length of the loop memory 12, the processing unit 11 reads the time data, the electrocardiogram data, and the triaxial acceleration data from the loop memory 12, and further receives the ID from the ID storage unit 16. Read. Then, the processing unit 11 outputs the read time data, electrocardiogram data, triaxial acceleration data, and ID to the mobile phone 26 via the interface 18 (S105).

  In the mobile phone 26, the data processing unit 43 temporarily stores the time data, electrocardiogram data, triaxial acceleration data, and ID input from the interface 52 in the data storage unit 44. The data processing unit 43 reads out the GPS positioning data calculated in the GPS positioning unit 46, and also reads out the time data, electrocardiogram data, triaxial acceleration data, and ID stored in the data storage unit 44. Are transmitted to the electrocardiogram analysis center terminal 34 by the transmitter / receiver 41 via the nearest base station 33 and the communication network 28 (S106).

  In S105, when the processing unit 11 outputs various data to the mobile phone 26, the process returns to S101. In this manner, the processing from S101 to S105 is repeated, and in S106, various data are transmitted from the mobile phone 26 to the electrocardiogram analysis center terminal 34 for each data corresponding to the set data length of the loop memory 12. As described above, since data is transmitted from the loop memory 12 to the electrocardiogram analysis center terminal 34 for each set data length, the memory portion storing the transmitted data is overwritten to store new data. It can be used repeatedly, and even if the capacity of the memory is not large, an electrocardiogram can be measured when necessary for a long period of time, which is efficient.

  In S101, when the processing unit 11 determines that the mode in the mode switch 9 is not the event electrocardiogram measurement mode (ie, the electrocardiogram continuous measurement mode) (NO), the measurement process for the event electrocardiogram measurement mode ends. .

[Continuous ECG measurement mode]
FIG. 8 is a processing flow of electrocardiogram measurement in the electrocardiogram continuous measurement mode. As shown in FIG. 8, the processing unit 11 determines whether or not the mode in the mode switch 9 is the electrocardiogram continuous measurement mode (S201). When the mode is the electrocardiogram continuous measurement mode (YES), the processing unit 11 determines the potential of the biological electrodes 4 and 4 processed by the potential processing unit 8, the current time data output from the clock 13, and the three axes. The triaxial acceleration data output from the acceleration sensor 17 is continuously stored in the loop memory 12 (S202). Since the biological electrodes 4 and 4 are mounted on the surface of the living body between the abdomen and the chest of the subject A, the potential of the biological electrodes 4 and 4 processed by the potential processing unit 8 is basically an electrocardiogram. It is. The arrhythmia detection unit 24 determines whether or not the electrocardiogram data output by the potential processing unit 8 includes an arrhythmia (S203). When the arrhythmia is not included in the electrocardiogram data (NO), the process returns to S201, and S201 to S203 are repeated. Therefore, as long as no arrhythmia is detected in the electrocardiogram data, various data including the electrocardiogram data are stored in the loop memory 12. However, every time the data amount stored in the loop memory 12 exceeds the data amount for one cycle, a new data is stored. Data will be overwritten.

  In S203, when the arrhythmia is detected by the arrhythmia detection unit 24 (YES), the processing unit 11 performs various data for the set data length of the loop memory 12 from a predetermined number of seconds before the arrhythmia is detected, for example, 1 minute before. That is, the time data, electrocardiogram data, and triaxial acceleration data are read from the loop memory 12 and the ID is read from the ID storage unit 16. Then, the processing unit 11 outputs the read various data to the mobile phone 26 via the interface 18 (S204).

  In the mobile phone 26, the data processing unit 43 temporarily stores the time data, electrocardiogram data, triaxial acceleration data, and ID input from the interface 52 in the data storage unit 44. The data processing unit 43 reads out the GPS positioning data calculated in the GPS positioning unit 46, and also reads out the time data, electrocardiogram data, triaxial acceleration data, and ID stored in the data storage unit 44. Are transmitted to the electrocardiogram analysis center terminal 34 via the nearest base station 33 and communication network 28 by the transmission / reception unit 41 (S205). As described above, since the electrocardiogram data (pre-event electrocardiogram) before the occurrence of arrhythmia, the electrocardiogram data during the occurrence of arrhythmia, and the three-axis acceleration data are transmitted to the electrocardiogram analysis center terminal 34, it is more reliable and detailed. Diagnosis of electrocardiogram data and the like is performed.

  In S204, when the processing unit 11 outputs various data to the mobile phone 26, the process returns to S201. As described above, the processing from S201 to S204 is repeated, and in S205, various data corresponding to the set data length of the loop memory 12 are output from the mobile phone 26 to the electrocardiogram analysis center terminal 34.

  In S201, when the processing unit 11 determines that the mode in the mode changeover switch 9 is not the electrocardiogram continuous measurement mode (the event electrocardiogram measurement mode) (NO), the measurement process for the electrocardiogram continuous measurement mode ends. .

<Electrocardiogram measurement by ECG measurement schedule>
Next, electrocardiogram measurement based on an electrocardiogram measurement schedule will be described. FIG. 9 shows an electrocardiogram measurement flow according to an electrocardiogram measurement schedule.

  As shown in FIG. 9, first, in the medical institution, along with the electrocardiogram measurement schedule for the subject A set by a doctor or the like, the subject name, ID, and setting are set by the operation unit 62 of the medical institution terminal 36. The electrocardiogram measurement start time and measurement end time in the specified period are input, and the electrocardiogram measurement schedule program creation unit 63 is made to create an electrocardiogram measurement schedule program (S301). The electrocardiogram measurement schedule program is an alarm program that causes the mobile phone 26 to generate an alarm at an electrocardiogram measurement start time, and an electrocardiogram measurement that causes the electrocardiogram measurement apparatus 1 to measure an electrocardiogram and transmit electrocardiogram data from the electrocardiogram measurement start time to the measurement end time. Includes programs.

  Then, the transmission / reception unit 61 transmits the electrocardiogram measurement schedule program created by the electrocardiogram measurement schedule program creation unit 63 to the mobile phone 26 and the electrocardiogram measurement apparatus 1 via the communication network 28 and the base station 33 (S302). In the mobile phone 26, the electrocardiogram measurement schedule program is received by the transmission / reception unit 41, and the data processing unit 43 stores the electrocardiogram measurement schedule program in the program storage unit 47 (S 303) and also through the interface 52, the electrocardiogram measurement device 1 (S304). In the electrocardiogram measurement apparatus 1, the processing unit 11 receives an electrocardiogram measurement schedule program via the interface 18, and stores this program in the storage unit 14 (S305).

  In the mobile phone 26, the program execution unit 48 executes an alarm program among the electrocardiogram measurement schedule programs stored in the program storage unit 47. That is, referring to the current time output from the clock 51, when the electrocardiogram measurement start time is reached, the alarm generator 49 notifies the subject A that the time has been reached for a predetermined time. An alarm or vibration alarm is generated (S306).

  In the electrocardiogram measurement apparatus 1, the processing unit 11 executes an electrocardiogram measurement program among the electrocardiogram measurement schedule programs stored in the storage unit 14. That is, when the mode changeover switch 9 is in the electrocardiogram continuous measurement mode, since the bioelectrodes 4 and 4 are in contact with the surface of the subject A so that the electrocardiogram is measured, the processing unit 11 automatically Then, the time data, the electrocardiogram data, and the triaxial acceleration data in the measurement time from the electrocardiogram measurement start time to the electrocardiogram measurement end time are read from the loop memory 12 and output to the mobile phone 26 together with the ID stored in the ID storage unit 16 ( S307). In the mobile phone 26, the data processing unit 43 transmits these various data and the GPS positioning data measured by the GPS positioning unit 46 to the electrocardiogram analysis center terminal 34 via the base station 33 and the communication network 28. (S309).

  On the other hand, when the mode change-over switch 9 is in the event electrocardiogram measurement mode, the biological electrodes 4 and 4 are not in contact with the surface of the living body, but in S306, an alarm is generated from the alarm generation unit 49 of the mobile phone 26 at the electrocardiogram measurement start time. Generated. Therefore, the subject A knows that the electrocardiogram measurement start time has arrived, and touches the biological electrodes 4 and 4 with both hands. As a result, an electrocardiogram is recognized by the electrocardiogram recognition unit 23 from the potentials of the biological electrodes 4 and 4 processed by the potential processing unit 8, and time data, electrocardiogram data, and triaxial acceleration data are recorded in the loop memory 12. At the same time, the processing unit 11 reads these various data for each set data length from the loop memory 12, and outputs the data together with the ID stored in the ID storage unit 16 to the mobile phone 26 (S308). Then, in the mobile phone 26, the data processing unit 43 sends these various data and the GPS positioning data measured by the GPS positioning unit 46 to the electrocardiogram analysis center terminal 34 via the base station 33 and the communication network 28. Transmit (S309).

  As described above, the electrocardiogram measurement schedule program is downloaded to the mobile phone 26 and the electrocardiogram measurement apparatus 1 and executed, whereby the electrocardiogram data and the triaxial acceleration data in the set time zone can be reliably measured.

The data control unit 55 stores these various data in the data storage unit 58. Further, the data control unit 55 causes the electrocardiogram analysis processing unit 57 to analyze the received electrocardiogram data (S402).

  Then, the electrocardiogram analysis processing unit 57 determines whether or not a serious arrhythmia such as ventricular extrasystole (PVC) or ventricular fibrillation (VF) has occurred in the electrocardiogram data (S403). Here, when a serious arrhythmia is detected in the electrocardiogram data (YES), the data control unit 55 refers to the ID registration list table, reads the subject name associated with the ID, and also stores the data storage unit 58. Time data and GPS positioning data are read out. Then, the data control unit 55 transmits the analysis result that the serious arrhythmia detected from the read subject name, time data and GPS positioning data and the electrocardiogram analysis processing unit 57 is detected to the transmission / reception unit. To 56. The transmission / reception unit 56 transmits the subject name, time data, GPS positioning data, and analysis result to the fire department terminal 37 and the ambulance vehicle terminal 39 (S404).

  In S403, the data control unit 55 is stored in the data storage unit 58 regardless of whether a serious arrhythmia is detected in the electrocardiogram data (YES) or not (NO). The ID, electrocardiogram data, arrhythmia analysis result, time data, triaxial acceleration data, and GPS positioning data are output to the transmission / reception unit 56 and transmitted to the medical institution terminal 36 (S405).

In the medical institution terminal 36, when the transmission / reception unit 61 receives the ID, electrocardiogram data, arrhythmia analysis result, time data, triaxial acceleration data, and GPS positioning data transmitted by the medical institution terminal 36 through the Internet 32, the data control unit 60 stores these various data in the data storage unit 64. Further, the data control unit 60 refers to the ID registration name table 67 from the ID stored in the data storage unit 64, reads the subject name registered in association with the ID, and causes the display unit 68 to display it. . Further, the data control unit 60 causes the display unit 68 to display the electrocardiogram data and the triaxial acceleration data on the same time axis. At this time, the time axis reflects the time data. Accordingly, the attending physician of the subject A refers to the display unit 68 and determines the activity state (exercising, resting, etc.) and posture (waking up) of the subject A based on the triaxial acceleration data. Or the like) and the electrocardiogram data can be grasped, and appropriate diagnosis can be performed.

  Further, the data control unit 60 outputs GPS positioning data to the GPS positioning data processing unit 66. Then, the GPS positioning data processing unit 66 specifies the position of the mobile phone 26 indicated by the GPS positioning data on the electronic map, and causes the display unit 68 to display the electronic map so that the specified position can be known. Further, the data control unit 60 causes the display unit 68 to display the arrhythmia analysis result stored in the data storage unit 64. Therefore, by referring to the screen of the display unit 68, the attending physician of the medical institution diagnoses by looking at the actual electrocardiogram while referring to the analysis result, and grasps the location of the subject A as necessary. Then, it is possible to call the mobile phone 26 and prepare for appropriate advice and treatment.

[Fire station terminal]
In the fire department terminal 37, when the transmitting / receiving unit 71 receives the subject name, time data, GPS positioning data, and the analysis result through the Internet 32, the data control unit 70 sends the GPS positioning data to the GPS positioning data processing unit 72. Output. The GPS positioning data processing unit 72 specifies the position indicated by the GPS positioning data on the electronic map, and causes the display unit 73 to display the electronic map so that the specified position can be understood. Here, the position specified on the electronic map is the position where the mobile phone 26 is present and the position where the subject A is present. Further, the data control unit 70 causes the display unit 73 to display the subject name, time data, and analysis results. As a result, the fire department can identify the location of the subject A in the serious arrhythmia by referring to the display unit 73 on the electronic map, and the name of the subject A, the arrhythmia can be identified to the fire brigade. After recognizing the symptom, the ambulance can be dispatched to the emergency site immediately.

[Ambulance terminal]
In the emergency vehicle terminal 39, when the transmission / reception unit 81 receives the subject name, time data, GPS positioning data, and the analysis result through the communication network 28 and the base station 33, the data control unit 80 stores the GPS positioning data in the car. The navigation processing unit 83 outputs the data. The GPS positioning unit 82 calculates the longitude and latitude at the position of the emergency vehicle terminal 39 that changes every moment based on the radio wave from the GPS satellite 53 received by the transmission / reception unit 81, and outputs it to the car navigation processing unit 83. The car navigation processing unit 83 specifies the position of the mobile phone 26 indicated by the GPS positioning data on the electronic map, that is, the position where the subject A is present, and the display unit 84 can recognize the specified position electronically. Display the map. At the same time, the car navigation processing unit 83 receives the GPS positioning data of the emergency vehicle terminal 39 output by the GPS positioning unit 82 and causes the display unit 84 to display the position of each GPS positioning data on the electronic map. Furthermore, the car navigation processing unit 83 displays a shortest path from the position of the emergency vehicle 38 (the position of the emergency vehicle terminal 39) to the position of the subject A (the position of the mobile phone 26) on the electronic map. Let me show you. The display unit 84 displays the position of the emergency vehicle 38 and the mobile phone 26 on the electronic map, the shortest path from the position of the emergency vehicle 38 to the position of the subject A, and is received by the transmission / reception unit 81. The subject name and the analysis result at the electrocardiogram analysis center terminal 34 are displayed.

  Accordingly, an emergency member who gets on the ambulance vehicle 38 and rescues the subject A can drive the ambulance vehicle 38 while confirming the display unit 84 and rush to the location of the subject A. Furthermore, since the name of the subject A and the symptoms of arrhythmia can be grasped, the subject A who is the rescue subject can be quickly identified at the emergency site, and the emergency treatment according to the symptoms can be smoothly performed. be able to.

  Although the first embodiment of the present invention has been described in detail above, it is needless to say that the present invention is not limited to the above-described embodiment.

  For example, the biological electrode 4 in the first embodiment may be formed so as to be exposed on both the inner and outer surfaces of the belt 2. Thereby, it is possible to cope with both the event electrocardiogram measurement mode and the electrocardiogram continuous measurement mode, and it is not necessary to replace the buckle 3 with the belt 2. The lead wire 7 may be built in the belt 2 and connected to the electrocardiogram measurement unit 6 of the buckle 3. The material of the bioelectrode 4 may be conductive stainless steel or the like instead of the conductive rubber. Further, a strap may be provided on the holder 25 of the mobile phone 26 and the strap may be hung on the belt loop.

  Further, in the first embodiment, instead of the belt 2, the bioelectrode 4 may be provided on another accessory such as a hanging band or a clothing accessory. Furthermore, the mobile phone 26 is not a general mobile phone but may be a general-purpose or dedicated mobile terminal such as a PDA. In that case, the portable terminal and the electrocardiogram measurement unit 6 may be integrated. Further, the electrocardiogram measurement unit 6 may be a separate device instead of being incorporated in the buckle 3 and attached to the belt 2. The communication network 28 may be a dedicated line in addition to the Internet.

  In the first embodiment, the alarm generation unit 49 of the mobile phone 26 generates an alarm for notifying the start time of the electrocardiogram. However, the electrocardiogram measurement apparatus 1 is provided with an alarm generation unit, and the electrocardiogram measurement apparatus 1 An alarm may be generated.

  In the first embodiment, various data are transmitted from the mobile phone 26 to the medical institution terminal 36 via the electrocardiogram analysis center terminal 34. However, the ID and electrocardiogram are directly transmitted from the mobile phone 26 to the medical institution terminal 36. Various data such as data and triaxial acceleration data may be transmitted.

<< Second Embodiment >>
Next, a second embodiment will be described with reference to FIG. The second embodiment is different from the first embodiment in the process of electrocardiogram measurement (refer to FIG. 8) in the electrocardiogram continuous measurement mode of the electrocardiogram measurement apparatus 1. Therefore, this point will be mainly described. Since the measurement is performed in the electrocardiogram continuous measurement mode, the belt 2 is attached to the subject A so that the biological electrodes 4 and 4 are in contact with the surface of the living body.

  In the second embodiment, various data stored in the loop memory 12 are transmitted to the electrocardiogram analysis center terminal 34 based on the value of the triaxial acceleration data detected by the triaxial acceleration sensor 17.

  That is, the triaxial acceleration sensor 17 outputs to the processing unit 11 that triaxial acceleration data exceeding a predetermined threshold has been detected. This threshold value is a value of triaxial acceleration that does not occur in daily life. When the electrocardiogram measurement unit 6 is tapped, the value of the triaxial acceleration data exceeds the threshold value. Therefore, when the subject A taps the electrocardiogram measurement unit 6, the processing unit 11 recognizes that the triaxial acceleration data exceeds the threshold value, and stores various data stored in the loop memory 12 to the electrocardiogram analysis center terminal 34. Send it.

  FIG. 11 shows an electrocardiogram measurement process flow in the electrocardiogram continuous measurement mode in the second embodiment. Compared with FIG. 8, S203A and S204A are different, but the other steps are the same as in FIG. is there. That is, as shown in FIG. 11, the mode switch 9 is set to the electrocardiogram continuous mode (S201, YES), and various data are continuously stored in the loop memory 12 (S202).

  When the subject A feels any symptom such as palpitation or arrhythmia, the electrocardiogram measurement unit 6 is tapped. Then, the triaxial acceleration sensor 17 detects that the triaxial acceleration data exceeds the threshold value, and outputs an electrocardiogram transmission command signal to the processing unit 11 (S203A). Then, the processing unit 11 outputs the electrocardiogram data for the set data length, the triaxial acceleration data, the time data, and the ID to the mobile phone 26 a predetermined number of seconds before the reception of the electrocardiogram transmission command signal, for example, one minute before. (S204A).

  From the mobile phone 26, the input time data, electrocardiogram data, triaxial acceleration data, ID, and GPS positioning data are transmitted / received by the transmitter / receiver 41 via the nearest base station 33 and communication network 28 to the electrocardiogram analysis center terminal. 34 (S205). Thus, since the electrocardiogram data and the triaxial acceleration data including the electrocardiogram data (pre-event electrocardiogram) before the electrocardiogram transmission command signal is received by the processing unit 11 are transmitted to the electrocardiogram analysis center terminal 34, More reliable and detailed diagnosis of ECG data and the like is performed.

  In S204A, when the processing unit 11 outputs various data to the mobile phone 26, the processing from S201 to S204A is repeated, and in S205, various data corresponding to the set data length of the loop memory 12 are transmitted from the mobile phone 26 to the electrocardiogram analysis. The point output to the center terminal 34 is the same as in the first embodiment.

  While the second embodiment of the present invention has been described above, the present invention is not limited to the second embodiment. For example, in the second embodiment, the processing unit 11 may compare the triaxial acceleration data with a threshold value.

<< Third Embodiment >>
Next, a third embodiment will be described with reference to FIGS. FIG. 12 shows a state in which the electrocardiogram measuring apparatus 1A according to the third embodiment is attached to the subject A. FIG. 13 is a functional block diagram of the electrocardiogram measurement apparatus 1A. FIG. 14 is a processing flow in the electrocardiogram measurement apparatus 1A. The third embodiment differs from the first embodiment in the configuration and processing of the electrocardiogram measurement apparatus 1A. Here, a description will be given focusing on the configuration and the like different from the first embodiment. In FIG. 12 and FIG. 13, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

<Configuration of electrocardiogram measurement device>
As shown in FIGS. 12 and 13, the electrocardiogram measurement apparatus 1 </ b> A has biological electrodes 4 </ b> A to 4 </ b> D. The bioelectrode 4A (first bioelectrode) is mounted at the intersection with the anterior axillary line at a height of the left fifth intercostal space (substantially V _5L position), and the bioelectrode 4B (second bioelectrode) At the height of the fifth intercostal space, it is attached to the intersection (substantially V _5R position) with the anterior axilla line. The biological electrode 4C is an indifferent electrode for grounding and is attached to the right thigh. These bioelectrodes 4A to 4C are electrically connected to the electrocardiogram measurement unit 6A by lead wires 7A to 7C, respectively. In addition, these bioelectrodes 4A to 4C are bioelectrodes of a type in which a conductive adhesive for attaching to the surface of a living body is applied to one surface of a nonwoven fabric and a potential is derived from the electrode element. The biological electrode 4D (third biological electrode) is exposed from the buckle 3 toward the front so as not to contact the surface of the living body, and is formed of conductive rubber. The biological electrode 4D is electrically connected to the electrocardiogram measurement unit 6A by a lead wire 7D.

  The processing unit 11A includes an electrocardiogram recognition unit 23A and an arrhythmia detection unit 24A. The electrocardiogram recognition unit 23A recognizes electrocardiogram data from the potential difference between the biological electrodes 4A and 4D. The arrhythmia detection unit 24 detects arrhythmia from electrocardiogram data between the biological electrodes 4A and 4B and between the biological electrodes 4A and 4D. Then, the processing unit 11A stores the electrocardiogram data between the biological electrodes 4A to 4D in the loop memory 12, stores the current time data output by the clock 13, and the triaxial acceleration output by the triaxial acceleration sensor 17. Control the storage of data. In particular, the processing unit 11A stores the electrocardiogram data detected between the bioelectrodes 4A and 4B in the loop memory 12 while the switch is in the ON state, and changes the potential difference between the bioelectrodes 4A and 4D by the electrocardiogram recognition unit 23A. When the electrocardiogram data is recognized, the electrocardiogram data between the biological electrodes 4A and 4D is stored in the loop memory 12. In addition, the processing unit 11A stores the program input from the mobile phone 26 in the storage unit 14, and reads and executes the stored program. The processing unit 11 </ b> A reads the electrocardiogram data, time data, and triaxial acceleration data stored in the loop memory 12, reads the ID from the ID storage unit 16, and outputs the ID to the mobile phone 26 via the interface 18.

<How to wear an electrocardiogram measurement device>
Next, a method for mounting the electrocardiogram measuring apparatus 1A will be described. The electrocardiogram measuring apparatus 1A is attached by putting on trousers or a skirt, inserting the belt 2 into a belt loop of the trousers or skirt, passing the tip of the belt 2 through the buckle 3, and closing the belt 2. Then, the bioelectrode 4A is mounted at the intersection with the anterior axilla line at the height of the left fifth intercostal space (substantially V _5L position), and the bioelectrode 4B is mounted at the height of the right fifth intercostal line with the anterior axillary line ( while attached to the position) of the substantially V _5R, attaching the bioelectrode 4C in the right thigh. When the subject A feels any symptom such as arrhythmia, the subject A touches the biological electrode 4D exposed to the buckle 3 with the right hand.

<Processing flow by electrocardiogram measuring device>
Next, a measurement flow by the electrocardiogram measurement apparatus 1A will be described with reference to FIG.

  First, the subject A wears the electrocardiogram measuring apparatus 1A. At this time, the biological electrodes 4A to 4C are also mounted on the surface of the living body as described above. Then, the subject A turns on the switch of the electrocardiogram measuring apparatus 1A. The processing unit 11A determines whether or not the switch is in the ON state (S501). If the switch is in the ON state, the ECG data detected by the bioelectrodes 4A and 4B and processed by the potential processing unit 8 is stored in the loop memory 12. (S502). Here, the biological electrode 4A is attached to the intersection with the anterior axillary line at the height of the left fifth rib, and the biological electrode 4B is attached to the intersection with the anterior axillary line at the height of the right fifth rib. The electrocardiogram detected by the biological electrodes 4A and 4B is CC5 induction. Further, the processing unit 11A uses the biological electrode 4C as an indifferent electrode, and uses the potential of the biological electrode 4C for processing of electrocardiogram data.

  The electrocardiogram recognition unit 23A determines whether or not electrocardiogram data is included from the potential between the biological electrodes 4A and 4D processed by the potential processing unit 8 (S503). If the subject A does not touch the bioelectrode 4D, the electrocardiogram recognition unit 23A does not recognize the electrocardiogram data based on the potential between the bioelectrodes 4A and 4D (NO). While the electrocardiogram recognition unit 23A does not recognize the electrocardiogram data, S501 to S503 are repeated. On the other hand, when the subject A feels some symptom such as arrhythmia and touches the biological electrode 4D exposed to the buckle 3 with the right hand, the electrocardiogram recognition unit 23A recognizes the electrocardiogram data at the potential between the biological electrodes 4A and 4D ( YES) Here, the bioelectrode 4A is mounted at the intersection with the anterior axillary line at the height of the left fifth intercostal space, and the potential of the bioelectrode 4D is the right-hand potential, so the electrocardiogram detected by the bioelectrodes 4A and 4D. Data are induction II.

  When the electrocardiogram recognition unit 23A recognizes the electrocardiogram data (YES), the processing unit 11A causes the CC5 lead electrocardiogram data detected by the bioelectrodes 4A and 4B, the lead II electrocardiogram data detected by the bioelectrodes 4A and 4D, Various data such as current time data output from the clock 13 and triaxial acceleration data output from the triaxial acceleration sensor 17 are stored in the loop memory 12 (S504). Then, the processing unit 11A determines whether or not the amount of data stored in the loop memory 12 has reached the set data length of the loop memory 12 (S505), and while it has not reached the set data length (NO) , The process returns to S504, and various data are continuously stored in the loop memory 12. The set data length is set within a data amount for one cycle in the loop memory 12 for each parameter.

  In S505, when the data amount reaches the set data length of the loop memory 12, the processing unit 11A causes the CC5 lead electrocardiogram data (pre-reading) before the lead II electrocardiogram data is recognized as the potential between the biological electrodes 4A and 4D. It is determined whether or not event electrocardiogram data) is stored in the loop memory 12 (S506). As soon as the electrocardiogram data is recognized as the potential between the bioelectrodes 4A and 4D, the CC5 lead pre-event electrocardiogram data is stored in the loop memory 12. Therefore, if the processing unit 11A determines that the CC5 lead pre-event ECG data is stored in the loop memory 12 (YES), the processing unit 11A includes the pre-event ECG data and is continuously detected thereafter. The electrocardiogram data, the electrocardiogram data of the second lead detected by the biological electrodes 4A and 4D, the time data, and the triaxial acceleration data are read, and the ID is further read from the ID storage unit 16. Then, the processing unit 11A outputs the read various data to the mobile phone 26 via the interface 18 (S507).

  Then, in the mobile phone 26, the data processing unit 43 temporarily stores the time data input from the interface 52, electrocardiogram data for two channels, triaxial acceleration data, and ID in the data storage unit 44. The data processing unit 43 reads out the GPS positioning data calculated in the GPS positioning unit 46, and also reads out the time data, electrocardiogram data, triaxial acceleration data, and ID stored in the data storage unit 44. Are transmitted to the electrocardiogram analysis center terminal 34 via the nearest base station 33 and communication network 28 by the transmission / reception unit 41 (S509).

  Subsequently, S501 to S506 are processed and various data are stored in the loop memory 12. In S506, the CC5 lead pre-event ECG data is already transmitted to the ECG analysis center terminal 34 in S509, and the loop is performed. Since various new data are overwritten and stored in the storage area of the memory 12, the CC5 lead pre-event ECG data does not exist in the loop memory 12 (NO). Therefore, the processing unit 11A reads CC5 lead ECG data, lead II electrocardiogram data, time data, and triaxial acceleration data that do not include pre-event ECG data, and further reads an ID from the ID storage unit 16. Then, the processing unit 11A outputs the read various data to the mobile phone 26 via the interface 18 (S508).

  Similarly to the above, the cellular phone 26 transmits various data and GPS positioning data to the electrocardiogram analysis center terminal 34 via the nearest base station 33 and the communication network 28 (S509). Thereafter, as long as the switch of the electrocardiogram measurement apparatus 1A is in the ON state, the processes of S501 to 509 are repeated. On the other hand, when the switch of the electrocardiogram measurement apparatus 1A is not in the ON state, that is, in the OFF state, the measurement is completed.

  Further, in the electrocardiogram measurement apparatus 1A, similarly to the electrocardiogram measurement apparatus 1 in the first embodiment (see FIG. 8), when the arrhythmia recognition unit 23A detects arrhythmia in the electrocardiogram data detected by the biological electrodes 4A and 4B, The processing unit 11A sends various data for the set data length of the loop memory 12 from the time point, for example, 1 minute before the arrhythmia is detected, that is, time data, electrocardiogram data, and triaxial acceleration data from the loop memory 12. In addition to reading, the ID is read from the ID storage unit 16. Then, the processing unit 11 outputs the read various data to the mobile phone 26 via the interface 18. Then, the mobile phone 26 transmits various data and GPS positioning data to the electrocardiogram analysis center terminal 34 via the nearest base station 33 and the communication network 28. The processing of the electrocardiogram measurement system after the transmission of various data to the electrocardiogram analysis center terminal 34 is the same as that in the first embodiment (refer to FIG. 10).

  As described above, in the third embodiment, electrocardiogram data for two channels of CC5 lead and lead II is measured, transmitted to the electrocardiogram analysis center terminal 34, and processed in the electrocardiogram measurement system. Therefore, according to the third embodiment for measuring the electrocardiogram data for one channel, the third embodiment for measuring the electrocardiogram data for two channels can analyze and diagnose the electrocardiogram in more detail such as arrhythmia and ischemia. Can do. Whether or not the symptom felt by the subject A is related to arrhythmia can be diagnosed from the electrocardiogram data.

<< Fourth Embodiment >>
Next, a fourth embodiment will be described with reference to FIG. FIG. 15 is a functional block diagram of an electrocardiogram measurement apparatus 1B according to the fourth embodiment. Therefore, the description will focus on the configuration and the like that are different from the third embodiment. In FIG. 15, the same or corresponding parts as those in the third embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

  The fourth embodiment differs from the third embodiment in the configuration and processing of an electrocardiogram measurement apparatus 1C. That is, the conductive rubber bioelectrode 4D exposed to the buckle 3 has a push button structure, and the electrocardiogram measurement apparatus 1B has a press detection unit 10 that detects that the bioelectrode 4D is pressed. ing. That is, the press detection unit 10 has a structure in which the circuit board portion immediately below the bioelectrode 4D in the electrocardiogram measurement unit 6B becomes conductive when the bioelectrode 4D is pressed. The fact that the electrode 4D has been pressed is output to the processing unit 11B.

  In the processing in the electrocardiogram measurement apparatus 1B, instead of determining whether or not there is electrocardiogram data between the biological electrodes 4A and 4D in S503 of FIG. 14 in the processing flow in the third embodiment, in the fourth embodiment, Then, it is determined whether or not the pressing detection unit 10 detects that the biological electrode 4D is pressed.

  Thus, the electrocardiogram measuring apparatus 1B is configured, and the biological electrode 4D also serves as a switch for starting recording of electrocardiogram data measured by the biological surfaces 4A and 4D at the time of the event. Therefore, the electrocardiogram measuring apparatus 1B is configured in a space-efficient manner rather than separately providing a switch for starting recording of electrocardiogram data and a bioelectrode, and for the subject A, the switch and the bioelectrode are pressed down. There is no need to touch. Further, measurement and transmission of electrocardiogram data and the like can be prevented when the hand touches the bioelectrode 4D unintentionally, and transmission of electrocardiogram data and the like when the bioelectrode 4D is intentionally pressed by the right hand. It can be performed. The trigger for transmitting the electrocardiogram data or the like is that the bioelectrode 4D is pressed, and various data are transmitted as long as the hand continues to touch the bioelectrode 4D even if the bioelectrode 4D is not continuously pressed. It may be continued.

  Also in the fourth embodiment, since the electrocardiogram data for two channels can be measured as in the third embodiment, the electrocardiogram is analyzed in more detail than arrhythmia or ischemic as compared with the first embodiment. Can be diagnosed. Whether or not the symptom felt by the subject A is related to arrhythmia can be diagnosed from the electrocardiogram data.

  Although the fourth embodiment of the present invention has been described above, the present invention is not limited to the fourth embodiment. For example, in the fourth embodiment, the pressing detection unit 10 has a push button switch structure in which the circuit board part in the electrocardiogram measurement unit 6B is brought into conduction when the biological electrode 4D is pressed. Instead, a pressure sensor or the like that detects that the biological electrode 4D is pressed with a pressure equal to or higher than a predetermined threshold may be used.
