The biological signal recording device 2 is approximately the same size as a recording device of a conventional Holter monitor, and can be carried by a subject in a pocket or on a waist belt. is there.

Next, the operation of the present system will be described based mainly on the configuration of the biological signal detecting device 1 shown in FIG. 2 and the configuration of the biological signal data recording device 2 shown in FIG. First, it is assumed that the biological signal data detection device 1 is directly attached to the chest of the subject by the adhesive gel 32. Further, it is assumed that the subject puts the biological signal recording device 2 in a pocket of clothes.

In this state, when the power is turned on and the operation starts, the biological signal detecting device 1
The detection processing unit 13 detects the QRS wave of the ECG waveform in real time, and outputs a QRS synchronization signal to the signal transmission control unit 16 each time the detection is performed. Thereby, the signal transmission control unit 16
Transmits this signal as a wireless signal. On the other hand, the ring buffer memory 14 stores the ECG waveform data supplied from the A / D converter 12 while sequentially rewriting data from the current time to a time before a predetermined time.

On the other hand, in the biological signal data recording device 2, the reception / demodulation unit 41 receives the QRS synchronization signal given from the biological signal detection device 1 and sends it to the MPU 42 as an interrupt signal. When the MPU 42 receives this QRS synchronization signal as shown in FIG. 7 (S1), the MPU 42 refers to the internal clock and sets the interval of the QRS synchronization signal, ie, R
-Detect R interval data and store it in its own memory (S2). Then, the MPU 42 analyzes the RR interval (S3). This analysis is the primary analysis.

FIG. 8 shows an example of this primary analysis. As shown in this figure, based on the stored RR interval data, the MPU 42 performs RR extension / shortening analysis, RR fluctuation analysis,
Perform heart rate analysis. R-R extension / shortening analysis uses the latest R
The difference between the R interval and the preceding RR interval, or the average R
This is an operation for obtaining a difference from the -R interval. The RR fluctuation analysis is an operation of calculating an average RR (heart rate) fluctuation rate at a stage when a certain time or a certain number of RR intervals are obtained.

The MPU 42 compares the above analysis results with the respective judgment criteria, and sends a detailed data request signal when it is judged that any of the results has a remarkable change. That is, if it is determined that detailed data is required as shown in FIG. 7 (S4), a signal for requesting ECG waveform data, that is, a data request signal is transmitted from the transmission unit 47 (S5).

On the other hand, when the subject feels sick, etc., the subject presses the operation button 46.
Also at this time, the MPU 42 causes the transmission unit 47 to transmit a data request signal.

On the other hand, in the biological signal detection device 1, upon receiving the data request signal, the command receiving unit 15 stores the data request signal in the ring buffer memory 14 and starts n
The ECG waveform data up to two seconds before is sent to the data recording device 2 via the signal transmission control unit 16.

The MPU 42 of the biological signal recording device 2
The ECG waveform data is received as shown in (6) (S6).
Is stored in its own memory (S7).
Then, the MPU 42 performs a secondary analysis by referring to the ECG waveform data and the RR interval data stored so far (S8).

FIG. 9 schematically shows a process in which a data request signal is generated from the biological signal recording device 2 and the signal reaches the biological signal detection device 1 and becomes a data request interrupt signal in the command receiving section 15.

As shown in FIG. 10, the biological signal detecting device 1
When receiving a data request signal, it sends out ECG waveform data for a fixed time (n seconds) before receiving the data request signal. Therefore, the biological signal recording device 2 changes (1) the data before the occurrence of the event and (2) the event by changing the time from the occurrence of the event causing the data request to the transmission of the actual data request signal. One of data including occurrence and (3) data after occurrence of an event can be selected. This time is set in a program used by the MPU 42. This time is also determined by the timing at which the subject presses the operation button 46.

FIG. 11 shows the processing from the output of the data request signal by the MPU 42 to the execution of the secondary analysis. First, ECG waveform data is requested from the biological signal detection device 1 (S11), and the time at that time is read (S12).
When the waveform data is received (S13), the waveform data is stored in its own memory together with the time (S14). Next, the waveform data is analyzed in detail based on the information obtained by the primary analysis (S15), and as a result, it is determined whether or not the waveform data is formally registered (S15).
16). If it is to be registered, the waveform data is stored in the data memory 43 (S17). The data to be registered here includes not only the event occurrence time and waveform data but also the code of the event occurrence factor. If you decide not to register,
The waveform data stored in S14 is discarded. At this time, if necessary, the RR interval data stored in the memory is corrected.

The secondary analysis also includes noise identification processing. For example, when the event is noise generation as shown in FIG. 12, the QRS detection processing unit 1 of the biological signal data detection device 1
3 detects this noise as a QRS wave, and the signal transmission control unit 16 sends out a QRS synchronization signal. As a result, the MPU 42 of the data recording means 2 makes this QRS
It determines that the interval between the synchronization signals is shorter than the reference, and sends a data request signal to the data detection device 2 via the transmission unit 47.
For this reason, the data detection device 2 uses the ring buffer memory 14
Is read out and sent to the data recording device 2. MP of data recording means 2
Upon receiving this ECG waveform data, U42 performs a secondary analysis. That is, here, the RR used in the primary analysis was used.
Performs the matching process with the interval. Then, when it is determined that there is noise, the ECG waveform data used in the secondary analysis is discarded without registration and is discarded.
Correct the error location at the R interval.

FIG. 13 shows the data memory 4 by the secondary analysis.
3 shows the contents of the data registered and the contents displayed by the personal computer 60 based on the contents.

In the primary analysis, the criteria can be downloaded from the personal computer 60 and can be changed. For example, if it is known that the subject has atrial fibrillation, it may be set so that the algorithm for determining whether the RR interval is extended or shortened is not used.

During the above processing, if the MPU 42 does not receive the QRS synchronizing signal continuously for a certain period of time or more, an alarm is generated by an alarm means (not shown) assuming that an abnormality has occurred on the biological signal detecting device 1 side. It has become.

In order to save power and reduce noise, the MPU 42 stops the ECG waveform data reception processing function except when outputting a data request signal.

Since the MPU 42 does not need high-speed processing except during the secondary analysis processing, the processing clock speed is set low. This can also reduce power consumption.

According to the present embodiment, when a detailed data request event occurs, the time when the event occurs and the ECG waveform data before that time can also be symmetrical in recording, so that more detailed analysis can be performed. It can be carried out.

Further, according to the present embodiment, since the biological signal detecting device 1 and the biological signal recording device 2 are both attached to the subject, the radio wave reach can be shortened. In this case, the power consumption required for transmission can be reduced. Also, according to the present embodiment, the RR interval is referred to during the secondary analysis,
The approximate position of S is known, and the process of waveform analysis is simplified.

Next, a second embodiment of the present invention will be described. This embodiment is different from the first embodiment in that
As shown in FIG. 14, the biological signal data detecting device 1A
When the second biological signal transmitting means 70 provided in place of the first biological signal transmitting means receives the data request signal via the first receiving means 7, it is detected by the electrode. The biological signal is transmitted in real time via the first transmitting means for a predetermined time. Other configurations are the first
This is the same as the embodiment. For this reason, the biological signal data recording device 2 receives this biological signal, and
The subsequent analysis and subsequent processing are the same as in the first embodiment.

According to the present embodiment, the biological signal before the occurrence of the event cannot be stored, but the configuration of the data detecting device can be simplified.

[0054]

It outputs continuous biosignals only when requested. For this reason, it is not necessary to always transmit a biological signal unlike the related art, and the power consumed by the biological signal detection device can be reduced. For this reason, it is not necessary to replace even a small battery for a long time, and the device can be reduced in size and weight. Therefore, there is no problem even if this biological signal detection device is worn on a living body and used for a long time, and there is no need to bother with a lead wire as in the related art. It can be carried out. Further, according to the present invention, it is possible to record a point in time at which an event causing an abnormality in the cycle of the biological signal and ECG waveform data before that point occur.

According to the second aspect of the present invention, in the biological signal recording device, only necessary data is stored, so that the capacity of the entire storage means can be reduced.

According to the fourth aspect of the present invention, if the operation button is operated when a patient or the like wearing and carrying the present system feels an abnormality in the body, the biological signal at that time is stored. Extremely important data will be stored for later analysis.

According to the fifth aspect of the invention, in addition to having the same effect as that of the first aspect, since the first storage means is not required, the configuration of the biological signal detecting device is simplified. However,
The second storage means of the present invention stores only ECG waveform data after a time point at which an event that causes an abnormality in the cycle of the biological signal occurs.

According to the invention of claim 6, similarly to the invention of claim 2, in the biological signal recording device, only necessary data is stored, so that the capacity of the entire storage means can be reduced.
