For example, when placed in the V1 position, it is of great value for the evaluation of arrhythmia, and when placed in the V4 position or in the V5 position, the ST-T due to the ischemia or potassium abnormality of the patient is caused. Changes can be recorded effectively.

The structure of the main body of the electrocardiogram information collecting apparatus of the present example set as described above will be described below with reference to FIG. The outer shape of the main body 10 of the electrocardiogram information collecting apparatus of this example is the left and right electrodes 3.

And operate to record. That is, when pressed from the side of the flat cover 17 on the back surface of FIG. 2, the electrode portion 15 is deformed in the direction of the electronic circuit portion 100, closing both contacts of the switch portion 175 and pressing the electrode element 16 to the skin surface. . Therefore, the biological signal derived from the electrode element 16 is taken into the electronic circuit section 100.

Next, the detailed structure of the electronic circuit section 100 will be described with reference to the block diagram of FIG. In FIG. 3, 1

It is an input unit for outputting to the electrocardiogram processing unit 150.

A known method can be used for the process of detecting the electrocardiogram information from the potential difference between the electrodes in the electrocardiogram processing section. Therefore, the detailed description of the electrocardiogram process is omitted. The analog signal from each electrode may be converted into a corresponding digital signal by the input section 160, and the electrocardiogram processing section 150 may be controlled so as to detect an electrocardiogram from this digital signal.

Further, 170 is a power source, and a battery is used as a drive source in this example. Whether or not the drive power is supplied from this power source to each component is controlled by whether or not the switch portion 175 is closed. The recording memory 14
Holding power is constantly supplied to the recording memory 140 if necessary so that the stored contents of 0 are not destroyed. Also,
The power source 170 notifies the CPU 110 of the ON / OFF state of the switch unit 175 separately from the rising and falling of the power source. When the contact point of the switch unit 175 separates and becomes the OFF state. The CPU 110 can be promptly notified of this. Therefore, the CPU 110 turns off the switch by this signal.

However, the configuration of the output section 180 of the present example is not limited to the above example, and the measurement information of the present example device is output even when the external device 200 does not have a special input circuit. be able to. In this case, for example, the output unit 180 is configured as a DC-AC converter to convert the digital electrocardiogram information read from the recording memory 140 by the CPU 110 into a corresponding analog signal and supply the analog signal to an external device. You can

The connector 185 is a mini-jack and, for example, by outputting DC 0.5 V / mV from this, this can be input as a detection signal from a bioelectrode of a normal electrocardiograph, and an external device can output the signal. In the case of an electrometer, there is no need for any special configuration for this. Furthermore, in the above description, the case where the directly collected electrocardiogram information is output to the external device 200 has been described. However, the present invention is not limited to the above example, and for example, the output unit 180 may be provided with a configuration capable of converting an input signal into a corresponding acoustic signal and outputting the acoustic signal. After that, a telephone may be called to a medical institution, the acoustic signal may be transmitted to the telephone, and this may be converted into corresponding electrocardiogram information by an external device received through the telephone.

In the above description, the connector 185 of the output section 180 is preferably provided on an exposed portion of the electronic circuit 100 when the flat cover 17 is detached when the flat cover 17 is detachably constructed. Alternatively, when the connector 185 is configured by the minijack described above, it may be directly attached to the flat cover 17 or may be provided on the side surface of the device.

The electronic circuit section 100 of the main body of the electrocardiogram information collecting apparatus of the present example having the configuration shown in FIG.
It can be configured by one or a small number of ICs excluding the 0 connection wire, etc. For example, if the recording memory 140 is configured by an IC memory, it is possible to configure all the configurations by one IC, and the overall size is small. Can be configured to be lightweight,
It can be made as large as a pendant that hangs around the neck.

A recording method for recording an electrocardiogram by using the apparatus of the present example having the above configuration will be described below. The electrocardiographic information collection device of this example is always worn on a patient who may have a heart attack, and when the patient actually has an attack or when the patient has subjective symptoms, the patient himself / herself does not It is possible to collect the electrocardiogram information at that time without taking off or undressing.

For this reason, as shown in FIG. 1, the apparatus of this example is set so that the electrocardiogram information collecting apparatus main body 10 is in the vicinity of the above-mentioned measurement point in a state in which the apparatus is hooked directly on the skin surface from the neck and / or the right shoulder is covered. To place. Then wear clothes one by one. Regarding the position of the electrocardiogram information collecting apparatus main body 10 at this time, it is desirable that it should be located exactly on each measurement point, but if it is located near the measurement point to some extent, a substantially good measurement result can be obtained. be able to.

In this state, if the patient becomes aware of an abnormality in his / her heart during his / her daily life, he / she should grasp the electrocardiogram information collecting apparatus main body 10 at a previously recognized measuring point rather than on clothing, Or pull it down,
The left and right electrodes 30 and 40 are brought into close contact with the skin by shifting and positioning, and the electrocardiogram information collecting device main body 10 is pressed against the skin.

As a result, the left and right electrodes 30, 40 are brought into good contact with each other, and the electrocardiogram information collecting apparatus main body 10 is provided.
The electrode element 16 of 3 is brought into close contact with the skin, and the contact point of the switch member 175 is also closed, so that driving power is supplied from the power source 170 to each component shown in FIG. As a result, the CPU 110 starts the operation, activates the electrocardiogram processing unit 150, and extracts electrocardiogram information from the potential difference between the electrodes input via the input unit 160. Then, the extracted electrocardiogram information is sequentially stored in the recording memory 140. Then, when the pressing of the electrocardiogram information collecting unit main body 10 by the patient is released, the switch unit 1
The contact point 75 is released, and the CPU 110 terminates the electrocardiogram collection process and stops recording in the recording memory 140. Then, when the driving power supply from the power supply 175 drops, all operations are stopped.

If there is no room above, each electrode is in direct contact with the skin even if the electrocardiogram information collecting device body 10 is simply pressed from above the clothes, and a substantially perfect electrocardiographic wave is obtained. Shapes can be collected. In the electrocardiogram information collecting apparatus of this example, the recording memory 140 employs an internal loop recording method, and the recording memory 140 records only the latest predetermined amount of electrocardiographic information. Even when the recording state is long for a number of times, it is a state in which only the latest electrocardiographic information for a fixed time is recorded.

In this example shown in FIG. 3, the electrocardiogram processing section 150 is used.
Is 0.0 for every 4 mS with a sampling frequency of 250 Hz.
The electrocardiogram information is output at a resolution of 1 mV / Bit, and the recording memory 140 is configured to be capable of recording electrocardiogram leads for 1 CH for about 60 seconds. If there is a request for recording for a slightly longer time, the storage capacity of the recording memory may be increased, and if the sampling frequency or the resolution is reduced, it is possible to record for a longer time. As a result of examining the above-mentioned various points, the above-mentioned time is set because the electrocardiogram information can be analyzed in most cases if the recording for approximately 60 seconds is possible.

As described above, the electrocardiogram information at the time of a seizure or the like is stored in the recording memory 140, and after the seizure is subsided by taking appropriate measures, the electrocardiogram information collecting apparatus of this example is used in a hospital or the like. Bring it during the treatment period. In the medical institution that receives this, the external device 200 is connected to the output unit to read the stored electrocardiogram information. By analyzing this electrocardiogram information, it becomes possible to accurately grasp the electrocardiogram information when a seizure or the like occurs and to perform appropriate treatment. The example shown in FIG. 4 is an example in the case where the electrocardiogram information collecting apparatus main body 10 is pressed against the position of V5 described above.
As shown in FIG. 4, a very clear waveform could be collected.

As described above, according to the present embodiment, the electrocardiogram information can be collected while the clothing is worn by simply pressing the electrocardiogram information collecting apparatus body 10 of the present embodiment against the body from above the clothing. For example, by attaching it to a heart disease patient, the electrocardiographic waveform when a heart attack occurs can be reliably collected without imposing a heavy burden on the patient.

[Second Example of Embodiment of the Invention] In the first example of the embodiment of the invention described above, the switch unit 1
75 is provided on the side where the electrode element 16 is provided. Therefore, it is possible to reduce the restrictions when the output connector 185 is arranged in the electronic circuit 100 portion on the back surface of the flat cover 17. However, the present invention is not limited to the above example, and if the area where the output connector 185 is provided can be secured, this switch section may be provided on the back surface of the flat cover.
With this configuration, it is possible to simplify the switch opening / closing operation when the switch is pressed from the flat cover direction.

That is, it is not necessary to form the electrode element portion with a material having flexibility, and the switch on the flat cover side can be opened and closed with very little deformation, which makes the structure easier. A second example of the embodiment of the present invention in which the switch portion is provided on the back surface of the flat cover will be described below with reference to FIG. FIG. 5 is a diagram for explaining the structure of the electrocardiogram information collecting apparatus main body according to the second example of the embodiment of the present invention. 5, the same components as those in the first example of the embodiment of the invention shown in FIG. 2 described above are denoted by the same reference numerals and detailed description thereof will be omitted. The configuration of the electronic circuit unit 100 can be the same as the configuration of FIG. 3 described above.

In the second example of the embodiment of the invention shown in FIG. 5, the electrode element 56 may be directly connected to the electronic circuit section 100 or may be connected by a signal line. In this case, it is not necessary to form this portion with a flexible material, and various conductive materials can be used. Plane cover 5
1 is also detachably provided, but in the present example, it is configured to have a little flexibility, and is deformed by pressing the flat cover 51 portion, and the switch portion 175b provided inside is deformed. The contact of is closed. As a result, the electrocardiogram information is collected.

Also in the second example of the embodiment of the invention described above, the same operational effect as that of the first example described above is achieved. Further, in the second example of the embodiment of the invention, it is not necessary to form the electrode element portion with a material having flexibility, and the deformation of the flat cover side is very slight so that the switch contact can be separated and contacted, It can be structurally easier.

[Other Examples of Embodiments of the Invention] In the above-mentioned example, the electrocardiogram information collecting apparatus main body 10 was hung by the chain 20, but the present invention is not limited to the above example, and the electrocardiogram is not limited thereto. The shape and the like are not limited as long as the information collecting device body 10 can be suspended. For example, change to a chain,
The electrocardiogram information collecting apparatus main body 10 may be hung down by a cable. In this case, the cable itself can be easily used to connect the left and right electrodes 30, 40 and the electrocardiogram information collecting device body 10. For example, the central portions of the cables up to the left and right electrodes 30 and 40 may be formed of a conductive material, for example.

Further, in the above description, the IC memory is used as the recording memory 140 and the recorded contents are read out from the output section 180, but the present invention is not limited to the above example, and the recording memory is not limited thereto. 140 itself is configured to be removable, and the output unit 180 and the connection 1
It is also possible to omit 85. In this case, only the memory chip is attached to the detachable connector, and this memory chip is attached to the memory reading unit in the external device so that the recorded contents can be read out. With the above configuration, the structure can be simplified.

Further, the recording memory 140 is not an IC memory but a system of recording the electrocardiogram information collected in the recording medium, so that only this recording medium is taken out and set in the reading device of the external device to read the recording information. You may do it. Any structure can be adopted as long as it is small and lightweight, and it may be a magnetic disk type or a cartridge type magnetic recording medium. Further, a method of recording on an endless magnetic tape may be used. Further, it goes without saying that it may be a magneto-optical disk.

That is, the flexible disk system of a small magnetic recording system, the magnetic disk system, or the magneto-optical disk system may be used, and the recording system is not limited at all. However, since it is used by hanging it down from the neck, it is desirable to be as small and lightweight as possible. Further, it is not limited to the case where the recorded electrocardiogram waveform can be read out as digital data by an external device. That is, even if the electrocardiogram information is recorded so that it can be visually displayed, it is possible to examine the electrocardiogram waveform during an attack.For example, by burning the electrocardiogram waveform on the film, the film can be removed. The electrocardiographic waveform may be configured to be recognizable.

[0041]

As described above, according to the present invention, it is possible to collect electrocardiographic information by simply pressing the body of the electrocardiographic information collecting device, which is placed on the chest, from above the clothes while wearing the clothes. For example, by attaching it to a heart disease patient, the electrocardiographic waveform when a heart attack occurs can be reliably collected without imposing a heavy burden on the patient.
