Description

The present invention relates to an electrocardiogram sensor sheet.

In recent years, interest in health care has increased, and more and more people are using wearable devices to acquire biometric information on a daily basis. For example, when the state of electrical activity of the heart (cardiac action potential) is measured as biological information and the electrocardiogram waveform is continuously acquired, an electrocardiogram pad (electrode pad) for electrocardiography is placed on the chest of a person. Need to paste. Since the electrocardiogram waveform changes greatly depending on the position where the electrocardiogram pad is attached, it is difficult to stably measure the cardiac action potential every time.

To allow accurate and repetitive placement of ECG leads without knowing the previous placement, for example, multiple electrodes in a predetermined pattern to transmit electrical signals from the patient to the ECG device. An electrocardiogram sensor sheet to be worn on the chest of a patient formed by a flexible sheet having a first means for positioning the upper end of the device in the sternum valley and a second means for positioning the device in the sternum valley. There is known an electrocardiogram sensor sheet which has means and allows the positioning of electrodes to occur repeatedly at the same position by positioning the device in the valley of the clavicle and the valley of the sternum (see, for example, Patent Document 1).

FIG. 3 is a diagram illustrating a method of using the electrocardiogram sensor sheet according to the embodiment of the present invention.

The user peels off the release paper 30 from the electrocardiogram sensor sheet 10 and attaches the electrocardiogram pad 20 to a predetermined position of the body 100 (near the position where the heart exists in the chest).
When the electrocardiogram pad 20 is attached to the body 100 for the first time, the attachment position of the electrocardiogram pad 20 is determined while observing the waveform of the electrocardiogram monitor connected to the electrocardiogram pad 20 wirelessly or by wire. Specifically, the place where a stable waveform can be obtained is set as the attachment position of the electrocardiogram pad 20.
When the electrocardiogram pad 20 and the electrocardiogram monitor are connected wirelessly, for example, a smartphone on which a dedicated application is installed is used as an electrocardiogram monitor, measurement data is transmitted from the electrocardiogram pad 20 to the smartphone by wireless communication, and the electrocardiogram waveform is confirmed on the smartphone. do. When the electrocardiogram pad 20 and the electrocardiogram monitor are connected by wire, for example, a connection terminal is provided on the surface of the electrocardiogram pad 20, the electrocardiogram pad 20 and the wearable device are connected via the connection terminal, and the electrocardiogram waveform is formed by the wearable device. To confirm.

After the attachment position of the electrocardiogram pad 20 is determined, the attachment position is recorded using the release paper 30 peeled off from the electrocardiogram sensor sheet 10. Specifically, the scale 33 formed on the release paper 30 is brought into contact with a characteristic portion of the body 100 such as the clavicle and the nipple, and the attachment position of the electrocardiogram pad 20 is recorded on the release paper 30. That is, the scale 33 of the release paper 30 is provided with a first mark corresponding to a characteristic portion of the body 100 and a second mark corresponding to the electrocardiogram pad 20 arranged on the release paper 30.

When the electrocardiogram pad 20 is attached to the body 100 from the second time onward, first, the release paper 30 recording the attachment position of the electrocardiogram pad 20 is brought into contact with the predetermined position of the body 100. At this time, the first mark provided on the scale 33 of the release paper 30 is aligned with the characteristic portion of the body 100, and the release paper 30 is brought into contact with a predetermined position of the body 100.

Subsequently, the electrocardiogram pad 20 is arranged at a predetermined position on the release paper 30 in accordance with the second mark provided on the scale 33 of the release paper 30. At this time, it is preferable to attach a part of the electrocardiogram pad 20 to the release paper 30 so that the attachment position does not shift. Since the release paper 30 is transparent, the attachment position of the electrocardiogram pad 20 can be confirmed via the release paper 30. After arranging the electrocardiogram pad 20 at a predetermined position, only the release paper 30 is removed from the body 100 and the electrocardiogram pad 20 is attached to the body 100 so that the attachment position of the electrocardiogram pad 20 does not shift.

As described above, according to the electrocardiogram sensor sheet 10 of the present embodiment, the electrocardiogram pad 20 can be accurately and easily attached to the same position each time without using a tool. Further, the electrocardiogram sensor sheet 10 of the present embodiment can be miniaturized because the electrocardiogram pads 20 can be individually attached to predetermined positions. Further, since the electrocardiogram sensor sheet 10 of the present embodiment can be miniaturized, even if it is worn like a wearable device, it can live as usual.
