Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrocardiogram management apparatus for detecting an abnormal electrocardiogram in daily life.

[0002]

As is well known, an electrocardiogram (electrocardiog) is used.
ram: ECG) is a macroscopic measurement of the action potential in the heart. The electrocardiogram is essential for the diagnosis of heart disease,
In particular, it is effective for diagnosing ischemic heart disease such as myocardial infarction and angina and arrhythmia. Such an electrocardiogram is obtained by attaching electrodes to at least two locations, preferably three locations, of the body of a subject and inducing a potential difference generated between these electrodes into an electrocardiograph. An electrocardiogram consists of a P wave that appears during atrial contraction, a QRS wave that appears during ventricular contraction, and a T wave that represents the process of repolarization of the ventricle.

Generally, such an electrocardiographic measurement is performed only in special cases such as a medical examination, and an electrocardiographic abnormality is often found in an electrocardiographic examination.

Conventionally, various health care devices have been proposed. For example, Japanese Utility Model Publication No. 2-61304 (hereinafter,
(Referred to as Prior Art 1), a toilet bowl has a blood pressure / pulse measuring means,
A body temperature measuring means, a weight measuring means and a urine analyzing means are provided,
There is disclosed a "health management device" capable of measuring blood pressure, pulse rate, body temperature and body weight at the time of urination or defecation, and performing urine analysis at once.

Further, Japanese Utility Model Laid-Open No. 63-109103 (hereinafter referred to as Prior Art 2) discloses a first filter having a wide pass band, a QRS wave and an S of an electrocardiogram signal.
A second filter having a narrow pass band of T level and a band elimination filter for eliminating the main component of the electrocardiogram signal;
By adding a switching circuit that detects a noise input and selects the electrocardiogram signal that has passed through the second filter instead of that of the first filter, even when noise is mixed in the electrocardiogram signal, There is disclosed an "electrocardiogram monitor" capable of diagnosing the presence or absence of arrhythmia or myocardial infarction.

Japanese Utility Model Publication No. 62-174506 (hereinafter, referred to as
Prior art 3) refers to a main body having detection means for detecting a biomedical signal, a magnetic recording medium, or a biomedical signal processing unit provided with each means for detecting, storing and reproducing an abnormal signal. A "carrying-type electrocardiogram information recording device" is disclosed, which is detachably provided, so that the device to be mounted can be selected according to the purpose at the time of starting the examination and the data can be organized easily.

Japanese Unexamined Patent Publication No. 2-17033 (hereinafter referred to as prior art 4) discloses a display unit for displaying at least one electrocardiogram waveform acquired before the start of measurement and an electrocardiogram waveform before the start of measurement. A "long-time small electrocardiogram analysis device" is disclosed, which is provided with a keyboard for selecting a template waveform so as to avoid erroneous recognition of the template waveform.

[0008]

However, the above-mentioned medical examination is carried out once a year at most, and there is a high possibility that the detection of abnormal electrocardiogram will be delayed. You can also go to the hospital frequently for ECG, but it is very cumbersome and unrealistic. Furthermore, the present situation is that the means for capturing daily changes in the electrocardiogram are not generally provided.

Therefore, it is an object of the present invention to provide means for performing early electrocardiographic abnormality detection by performing daily electrocardiographic management without time restriction by utilizing daily life of excretion.

[0010] Incidentally, the above-mentioned prior art 1 discloses only measuring blood pressure, pulse rate, body temperature and body weight at the time of urination or defecation, and analyzing urine at one time, and discloses nothing about performing an electrocardiographic test during excretion. There is no description suggesting it. Further, the prior art 2 only discloses an "electrocardiogram monitor" capable of diagnosing the presence or absence of arrhythmia or myocardial infarction in the electrocardiogram signal even when noise is mixed in the electrocardiogram signal. There is no disclosure of conducting an inspection, and there is no description suggesting it. Prior art 3 discloses a "portable electrocardiogram information recording device" in which a magnetic recording medium or a bio-signal processing unit is selectively attached to a main body depending on the purpose at the time of starting an examination to facilitate data organization. However, there is no disclosure about performing an electrocardiographic examination at the time of excretion, and there is no description suggesting that. Further, Prior Art 4 is an invention relating to a long-time small electrocardiogram analyzer that records and analyzes electrocardiogram waveforms over a long period of time by classifying them with template waveforms, and discloses nothing about performing an electrocardiographic examination during excretion. No, there is no description suggesting it.

[0011]

In the electrocardiogram management apparatus of the present invention, a toilet bowl having a toilet seat to which a toilet seat electrode is attached, a handle portion to which a handle electrode is attached, and a subject sitting on the toilet seat during excretion By holding the handle part with one hand in the state, the electrocardiogram inducing means capable of inducing the electrocardiogram signal of the subject from the toilet seat electrode and the handle electrode, and the electrocardiogram signal induced by this electrocardiogram inducing means. And a processing device for processing.

[0012] The above-mentioned processing device converts the electrocardiogram signal induced by the electrocardiogram inducing means into digitized time series electrocardiographic data, and measures the electrocardiographic data output from the A / D converting means. It is preferable to include an analysis unit that detects an arrhythmia, and a storage unit that stores the electrocardiogram data and the analysis result output from the analysis unit. Further, the processing device may further include means for determining an electrocardiogram abnormality from the analysis result and notifying the subject, or output means for displaying or recording the electrocardiogram data and the analysis result.

[0013]

When the subject sits on the toilet seat, both thighs of the subject come into contact with the electrodes of the toilet seat, and by gripping the handle electrodes of the handle part, an electrocardiogram signal is induced in the electrocardiogram guide part. The electrocardiogram signal induced by the electrocardiogram guide unit is processed by the processing device. Using the daily life of excretion, daily ECG management can be performed without any time constraint, and ECG abnormalities can be detected early.
