B-2. Operation of First Embodiment Next, the operation of the above-described first embodiment will be described. Here, FIG. 9 is a flow chart for explaining the operation of the electrocardiograph according to the first embodiment of the present invention. First, the person to be measured rotates the arm portion 2 by himself to bring the arm portion 2 from the folded state to the unfolded state, and while holding the first measurement electrodes 3 and 3 of the main body portion 1 with his right hand, The second measurement electrode 6 is pressed against the chest by sliding it through the gap between clothes, and the first switch 11 is operated to start the electrocardiographic measurement. Steps S10 to S20 described below are processes for measuring an electrocardiographic signal and recording it as electrocardiographic waveform data.

When the electrocardiographic measurement is started, the potential difference between the first measurement electrode 3 and the second measurement electrode is amplified by the differential amplifier 20 and supplied to the low pass filter 22 via the high pass filter 21. . The control unit 29 is supplied with electrocardiographic waveform data (digital data) from the A / D converter 24. The control unit 29 first, in step S10,
It is determined whether or not the memory switch (first switch 11) is on, and if the memory switch (first switch 11) is on, it is supplied from the A / D converter 24 in step S12. The electrocardiographic waveform data of digital data is stored in the RAM 30. Next, in step S14, it is determined whether the electrocardiographic measurement has elapsed for 10 seconds, and if 10 seconds have not elapsed, the process returns to step S10. Hereinafter, if the storage switch (first switch 11) is turned on, the electrocardiographic waveform data is stored in the RAM 30 for 10 seconds. When the electrocardiographic measurement has passed for 10 seconds, step S
The determination result in 14 is “YES”, and the step S
In step 16, the storage of the electrocardiographic waveform data is stopped, and the flag F is set to "1" in step S18. Then, the process is completed.

Next, steps S20 to S2 described below.
6 is a process of setting the measurement site (lead) for the electrocardiographic waveform data stored in the RAM 30 by the process described above. If any switch is operated and it is not the memory switch (first switch 11), the process proceeds from step S10 to step S20. In step S20, the operated switch is a setting switch for setting the measurement site (for example, the second switch 1).
It is determined whether or not 2). When the setting switch is operated, the process proceeds to step S22, and the flag F
Is "1". If the storage of the electrocardiographic waveform data has been completed by the processing described above, the flag F
Is "1". If the flag F is "1", the process proceeds from step S22 to step S24, and the measurement site of the electrocardiographic waveform data stored in the RAM 30 is set.

As a setting method, for example, a cursor is displayed on the display unit 4 together with the name of the measurement site (guide name),
With the second switch 12 and the third switch 13,
The cursor may be moved to the name of the corresponding measurement site and the measurement site may be selected. The measurement site selected in this way is stored in the register described as the site of the RAM 30 shown in FIG. 7 in correspondence with the stored electrocardiographic waveform data. At this time, in step S24,
Corresponding to the electrocardiographic waveform data, a process of storing the current time in the RAM 30 as time data is also performed. Next, in step S26, the flag F is returned to "0" and the process ends. On the other hand, even if the setting switch is operated, if the flag F is not "1", that is, if the electrocardiographic waveform data is not stored, the determination result in step S22 is "NO", and the measurement site is set. Not done

The measurement / storage of the electrocardiographic waveform data and the setting of the measurement site in steps 10 to S26 described above can be performed at any time, and by repeating the same processing, as described above, for example, 10 electrocardiographic waves are recorded. Shape data and its part data can be stored.

Next, when the storage of the electrocardiographic waveform data and the setting of the measurement site are completed, the patient sets the speaker 33.
With the switch on the transmitter of the telephone set, the transmission switch (for example, the first switch 11) is pressed to enter the transmission mode in which the stored electrocardiographic waveform data is transmitted to a center such as a hospital. Steps S28 and S30 described below are processes for transmitting the electrocardiographic waveform data, the region data, the time data and the member number to the diagnostic device installed in a center such as a hospital. When the transmission switch (first switch 11) is pressed, the process proceeds to step S28 via steps S10 and S20 shown in FIG. In step S28, it is determined whether or not the transmission switch has been pressed. If the transmission switch (first switch 11) is pressed, the process proceeds to step S30. In step S30, the electrocardiographic waveform data stored in the RAM 30, the site data (lead), the time data and the member number are converted into acoustic signals by the sound control unit 32 and applied to the transmitter of the telephone. The speaker 33 makes a sound report and transmits it to a diagnostic device installed in a center such as a hospital via a telephone line, and the process ends. Also,
If any switch other than the memory switch, setting switch, and transmission switch is operated, steps S10, S20,
After S28, the process proceeds to other processes.

Here, FIG. 10 is a schematic diagram showing a display example of the display unit 4 at the time of transmission. In transmission mode,
As shown in 0 (a), the dot matrix display of the display unit 4 displays the number of free spaces in the electrocardiographic waveform data storage unit (indicating how many more electrocardiographic waveform data can be stored).
In the illustrated example, "FREE-6" is displayed and 6
It indicates that there is a free space. FIG.
In the display example shown in (a), the character of the handset is displayed in order to indicate that the mode is for transmission by the telephone. When the second switch 12 is pressed in this state, as shown in FIG. 10B, the computer character is displayed instead of the handset character, and the character is directly attached to the diagnostic device. The transmission mode is set by the communication unit 9 (photocoupler including a phototransistor and a light emitting diode).

As described above, when the transmission switch (first switch 11) is pressed in the state shown in FIG. 10 (a), the display changes to that shown in FIG. 10 (c), and the electrocardiographic waveform data is displayed. Transmission starts. The transmission is sequentially transmitted from the most recent electrocardiographic waveform data (including the corresponding site data and time data) following the membership number, and the display during the transmission is shown in FIGS. 10 (c), (d), (e). ), Then (f). During transmission, the segment display provided in the lower part of the display unit 4 displays what number of electrocardiographic waveform data is being transmitted. FIG. 10C shows the first line, FIG. 10D shows the second line, and FIG. 10E shows the tenth line. During transmission, the number of display dots on the dot matrix display provided on the upper stage of the display unit 4 is sequentially increased according to the amount of transmitted data, thereby displaying the transmission status (transmitted data amount). , LED and the string "TRANSMIT" blink. The patient can know the amount of transmitted data (or the amount of untransmitted data) at the present time from the display of the segment display and the dot matrix display shown in the figure. Then, when all the electrocardiographic waveform data (including the corresponding site data and time data) have been transmitted,
As shown in FIG. 10F, a character string “FINISH” indicating the end of transmission is displayed on the dot matrix display section of the display section 4. After sending, it sounds an alarm,
After a predetermined time (for example, 5 seconds), the display returns to that shown in FIG.

On the other hand, in the diagnostic device 40 installed in a center such as a hospital, the control unit 43 executes a diagnostic / management program. The electrocardiographic waveform data, site data, time data, and member number transmitted via the telephone line are demodulated into digital data by the modem 41 and supplied to the control unit 43. Here, FIG. 11 is a flow chart for explaining the operation of the diagnostic apparatus according to the first embodiment. First, in step S40, the control unit 43 determines whether or not the data from the electrocardiograph is received, and if not received, the step S40 is repeatedly executed. On the other hand, when the data is received, the process proceeds to step S42, and the received electrocardiographic waveform data, site data, time data and member number are stored in the received electrocardiographic waveform data storage unit of the RAM 44. Next, in step S44, the personal data previously stored in the standard electrocardiographic waveform data storage unit of the RAM 44 is searched using the received member number as a key. Then, in step S46, the standard electrocardiographic waveform data in each lead of the corresponding member number is read, and the received electrocardiographic waveform data, site data, and time data are displayed together with the standard electrocardiographic waveform data in the display unit 45 or the printing unit. Either one or the other 46 is supplied to both and displayed / printed. The display unit 45 and the printing unit 46 graphically display the standard electrocardiographic waveform data and the received electrocardiographic waveform data as waveforms. In a center such as a hospital, a diagnosis is made by comparing the standard electrocardiographic waveform and the electrocardiographic waveform at the time of measurement, which are output by either the display unit 45 or the printing unit 46, or both.

In step S68, it is determined whether or not the transmission switch has been pressed. When the transmission switch (first switch 11) is pressed, step S7
Go to 0.

In step S70, the standard electrocardiographic waveform data stored in advance in the standard electrocardiographic waveform data storage section of the RAM 30 is used with the site data indicating the measurement site (lead) of the electrocardiographic waveform data stored in the RAM 30 as a key. Search for.
At this time, a plurality of measured electrocardiographic waveform data are stored, and if each is electrocardiographic waveform data at a different measurement site, standard electrocardiographic waveform data for each measurement site is searched. Alternatively, even if a plurality of measured electrocardiographic waveform data are stored, if the electrocardiographic waveform data is at the same measurement site, only the standard electrocardiographic waveform data at one measurement site is searched. Then, step S72
In, the standard electrocardiographic waveform data at the corresponding measurement site (lead) is read, and along with the standard electrocardiographic waveform data, the measured electrocardiographic waveform data, site data, and time data are converted into acoustic signals by the sound control unit 32. After the conversion, the speaker 33 attached to the transmitter of the telephone makes a sound and transmits it to a diagnostic device installed in a center such as a hospital via a telephone line.

Diagnostic device 40 installed in a center such as a hospital
Then, the electrocardiographic waveform data, site data, time data, and standard electrocardiographic waveform data received via the telephone line are demodulated into digital data by the modem 41, and then either the display unit 45 or the printing unit 46 is provided. By outputting either of them, the standard electrocardiographic waveform and the current electrocardiographic waveform are compared, and a diagnosis is made.

As described above, in the second embodiment described above, the standard electrocardiographic waveform data of the patient during normal operation is stored in advance in the electrocardiograph and the measured electrocardiographic waveform data is transmitted to the center such as a hospital. In this case, the standard electrocardiographic waveform data for the measurement site at normal times is also sent, so that a diagnostic device installed in a center such as a hospital can receive the standard electrocardiographic waveform data along with the received electrocardiographic waveform. Since it can be displayed / printed, it becomes easy to compare the standard electrocardiographic waveform with the current electrocardiographic waveform, and a quick and detailed diagnosis can be performed.

The standard electrocardiographic waveform data under running conditions, etc.
If it is stored in the M30 in advance, the electrocardiographic signal is continuously measured for 24 hours, and the measured electrocardiographic waveform data is compared with the standard electrocardiographic waveform data. That is, only when an electrocardiographic waveform that is not seen in normal times is measured (when it is considered that some abnormality has occurred), a warning is issued, and the measured electrocardiographic waveform data is stored. It is characterized by achieving the purpose.

It is almost the same as the embodiment. Further, also in the first or second embodiment, the configuration shown in FIGS. 14A and 14B may be used, and the disposable electrode 50 may be removed and used.

D-2. RAM Configuration of Third Embodiment Next, FIG. 16 is a schematic diagram showing a RAM configuration of an electrocardiograph according to the third embodiment. RA of electrocardiograph according to the third embodiment
The configuration of M30 is the same as that of the second embodiment, and as shown in FIG. 16, in addition to the display register, the time register, the flag F, the setting data storage unit and the electrocardiographic waveform data storage unit, the standard electrocardiographic waveform data storage The standard electrocardiographic waveform data storage unit is used to store standard electrocardiographic waveform data in various states in a patient's daily life,
Corresponding to the standard electrocardiographic waveform data, a measurement state (state in daily life: recumbent state, standing state, walking state, running state, etc.) is stored as state data. A reference number is given to the standard electrocardiographic waveform data to distinguish each standard electrocardiographic waveform data. When the measured electrocardiographic waveform data does not match any standard electrocardiographic waveform data, the closest standard electrocardiographic wave is obtained. The reference number of the shape data is added to the electrocardiographic waveform data.

D-3. Operation of Third Embodiment Next, the operation of the above-described second embodiment will be described. Here, FIGS. 17 and 18 are flowcharts for explaining the operation of the electrocardiograph according to the third embodiment. Steps S80 to S94 described below are processes for storing standard electrocardiographic waveform data in various states during normal patient conditions. Prior to the measurement, as shown in FIG. 15, the patient fixes the first disposable electrode 50 with the clip 53 provided at the bottom of the main body in the chest pocket.
a, second disposable electrode 50b, third disposable electrode 5
0c is stuck to a predetermined position on the chest.

In step S80, the control unit 29 first sets a setting switch (for example, the second switch 1) for the operated switch to measure the standard electrocardiographic waveform data.
It is determined whether or not 2). Then, when the setting switch is operated, the process proceeds to step S82, and the first state (for example, recumbent state) is set. The step S82
The state set by is displayed on the display unit 4, for example, "SLEE
It is displayed as a character string such as "P". Next, in step S84, a memory switch (for example, the first switch 11)
It is determined whether or not is pressed, and if the storage switch is not pressed, the step S84 is repeatedly executed. Here, the patient takes the state displayed on the display unit 4 and waits until he / she rests. At this time, the heart rate may be measured based on the electrocardiographic signal HS, and the heart rate may be displayed on the display unit 4 to serve as an index for determining whether or not the patient is resting.

When the patient takes the above state and becomes rested,
The memory switch (first switch 11) is pressed to store the standard electrocardiographic waveform data. When the memory switch is pressed, the process proceeds to step S86, and the electrocardiographic waveform data of the digital data supplied from the A / D converter 24 is stored in the RAM 30 as standard electrocardiographic waveform data.
Next, in step S88, it is judged whether or not the electrocardiographic measurement has elapsed for 10 seconds, and if it has not elapsed for 10 seconds, the process returns to step S86 and the standard electrocardiographic waveform data is read for 10 seconds.
Store in AM30. At this time, the state data indicating the state set in step S82 is also stored in the register described as the state of the RAM 30. When the electrocardiographic measurement has passed for 10 seconds, the determination result in step S88 is "YE
S ”, the process proceeds to step S90, and the storage of the electrocardiographic waveform data is stopped. Next, in step S92, it is determined whether or not the measurement and storage of the standard electrocardiographic waveform data in all normal states have been completed. If the measurement and storage of the standard electrocardiographic waveform data in all states have not been completed,
Return to step S82.

In step S82, the second state (for example, standing state) is set. The state set in step S82 is displayed on the display unit 4 as a character string such as "STAND". The patient takes the state displayed on the display unit 4 (standing state), waits until it rests, and presses the memory switch (first switch 11). When the memory switch is pressed, the above-described steps S86, 88, 90
And the standard electrocardiographic waveform data in the standing state together with the state data indicating the state set in step S82,
After storing in the RAM 30, the process returns to step S82 through step S92 described above.

Thereafter, steps S82 to S92 are repeatedly executed, and states other than those described above (walking state, running state, etc.)
The standard electrocardiographic waveform data in 1 is stored in the RAM 30 together with the state data indicating the state. Then, when the storage of the standard electrocardiographic waveform data in all states is completed, step S9
The determination result in 2 is "YES", and step S9
4, the flag F is set to "1". Then, the process is completed. In this way, steps S80 to S described above are performed.
By the processing of 94, the standard electrocardiographic waveform data in each state in the normal state is stored in the RAM 30 shown in FIG. 16 together with the state data indicating the state.

Next, steps S96 to S1 described below.
00 is a case where the measured electrocardiographic waveform data is compared with the standard electrocardiographic waveform data while measuring electrocardiographic signals continuously for 24 hours, and when none of the standard electrocardiographic waveform data matches, that is, some abnormality. This is a process of issuing a warning and storing the measured electrocardiographic waveform data only when it is considered that the error has occurred. If any switch is operated and it is not the setting switch (second switch 12), the control unit 29 proceeds from step S80 to step S96. In step S96, it is determined whether or not the operated switch is the continuous measurement switch (for example, the first switch 11) for starting the continuous measurement. Then, when the continuous measurement switch is operated, the process proceeds to step S98, and it is determined whether the flag F is "1". If the storage of the standard electrocardiographic waveform data is completed by the above-described processing, the flag F is "1". If the flag F is "1", the process proceeds from step S98 to step S100, and the continuous measurement process shown in FIG. 18 is executed.

When shifting to the continuous measurement process, first, in step S110, the electrocardiographic waveform data, which is the digital data of the electrocardiographic signal HS detected by the disposable electrode 50, is temporarily stored in the RAM 30. Next, step S11
In 2, it is determined whether or not the electrocardiographic measurement has elapsed for 10 seconds, and if it has not elapsed for 10 seconds, the process returns to step S110. Hereafter, step S is performed until the electrocardiographic measurement has passed for 10 seconds.
110 and 112 are repeatedly executed to store the electrocardiographic waveform data for 10 seconds in the RAM 30. And the electrocardiogram measurement is 1
When 0 second has elapsed, the process proceeds to step S114 to temporarily stop the storage of the electrocardiographic waveform data.

Next, in step S116, the standard electrocardiographic waveform data in the normal state and the measured electrocardiographic waveform data stored in advance in the above-described processing are sequentially compared. Next, in step S118, when the measured electrocardiographic waveform data does not match any of the standard electrocardiographic waveform data, that is, when it is considered that some abnormality has occurred, the process proceeds to step S120, and the sound control unit. A warning (alarm sound or the like) is issued from the speaker 33 by 32, and the electrocardiographic waveform data is stored in the electrocardiographic waveform data storage unit of the RAM 30 in step S122. At this time, the reference number of the closest standard electrocardiographic waveform data of the compared standard electrocardiographic waveform data is added to the electrocardiographic waveform data. Next, in step S124, it is determined whether or not the end switch for continuous measurement (for example, the first switch 11) has been pressed. If the end switch has not been pressed, the process returns to step S110 and the above-described processing is repeated. Run.

On the other hand, when the measured electrocardiographic waveform data matches any of the standard electrocardiographic waveform data, the measured electrocardiographic waveform data is directly stored without being stored in the RAM 30.
The process proceeds from step S118 to step S124, and it is determined whether or not the above-described end switch is pressed. If the end switch is not pressed, the process returns to step S110 and the above-described processing is repeatedly executed. Then, when the end switch is pressed, the continuous measurement process is ended,
The process shown in FIG. 17 ends. Further, the abnormal electrocardiographic waveform data stored in the RAM 30 is transmitted to a diagnostic device installed in a center such as a hospital and used for diagnosis, as in the first or second embodiment described above.

As described above, in the third embodiment, when the measured electrocardiographic waveform data does not match any of the standard electrocardiographic waveform data stored in advance in each state under normal conditions, When it is determined that some abnormality has occurred, the alarm control unit 32 issues an alarm from the speaker 33 and stores the electrocardiographic waveform data in the RAM 30. Therefore, only the electrocardiographic waveform data when the abnormality occurs is stored in the RAM 30, and the electrocardiographic waveform data at the time of the abnormality can be surely left. In addition, when storing the electrocardiographic waveform data, the reference number of the closest standard electrocardiographic waveform data among the standard electrocardiographic waveform data that was compared was added, so that the standard electrocardiogram It becomes easy to compare the shape data with the electrocardiographic waveform data at the time of abnormality, and a quick and detailed diagnosis can be performed. Moreover, since only the electrocardiographic waveform data at the time of abnormality is stored, continuous measurement can be performed for 24 hours without increasing the memory capacity.

In the third embodiment described above, when the measured electrocardiographic waveform data does not match any of the standard electrocardiographic waveform data stored in advance in the normal state in each state, automatic measurement is performed. Although the electrocardiographic waveform data measured in advance is stored, the electrocardiographic waveform data may be stored or not stored at the patient's own discretion.
