Description

A portable body composition measuring device capable of measuring electrocardiogram through Electrocardiogram (ECG) signal}

The present invention relates to a portable body composition measuring device, and more particularly, to a portable body composition measuring device capable of measuring an electrocardiogram through an ECG signal.

Body composition refers to the components that make up the human body. In other words, our human body is composed of water, protein, fat, minerals, and other major components in a certain proportion. These ratios differ according to gender, age, and individual characteristics, and are closely related to health.

This is a test that provides basic information to accurately grasp the state of the body by analyzing body composition and quantitatively analyzing the components of the human body. A healthy individual maintains an adequate amount of body composition in a balanced ratio with each other. When this balance is broken, body fat is excessively increased due to an imbalance between body components, which can lead to obesity, nutritional deficiencies due to lack of protein, edema due to increased extracellular water, and osteoporosis due to lack of minerals.

There are various methods for analyzing body composition, such as body measurement method, underwater body weight density method, Dexa method, CT method, and bioelectrical resistance method. Among them, the bioelectrical impedance analysis (BIA) is a method of analyzing body composition using electric current. When a minute alternating current flows through the human body, the current flows along water with high conductivity, and impedances are measured differently in body water, fat, and muscles depending on the amount of water or water. Since the measured impedance has a certain correlation with the body composition, it is possible to analyze the body composition by using this. In other words, in the bioelectrical resistance method, the fact that the human body is composed of highly conductive tissues (Conductor: lean) and low tissue (Insulator: body fat) is used, and that the ratio of the two tissues is reflected in the impedance measurement value.

The body composition analysis device using such a bioelectrical resistance method has an advantage in industrialization in that it can be usefully used because it is convenient to operate, easy to measure, and can derive rich results.

Conventionally, according to Korean Patent Laid-Open No. 2008-0099674, a hand electrode that is held by a subject to be measured, a connection means connecting the hand electrode to the main body, an acceleration sensor unit installed to know the subject’s posture, And a display unit that outputs a body composition measurement result, and an operation processing unit that calculates and processes information measured by the acceleration sensor unit to induce an accurate posture of the subject and calculates the body composition.

Conventionally, body composition can be measured, but there is a problem in that the impedance value varies depending on gender and body type.

When measuring the degree of obesity according to sex, in the case of a female, the measured body composition value may vary depending on whether the upper body is obese or the lower body is obese.

Accordingly, there is a need to develop a body composition analysis device that can increase the measurement accuracy of body composition and measure the amount of activity in real time according to the measured body composition result.

On the other hand, the electrocardiogram is the measurement and recording of the active current according to the contraction and expansion of the heart muscle by attaching an electrode from the outside.

In other words, the action potential generated when the heart muscle contracts and relaxes causes an electric current that spreads from the heart to the whole body. This generated electric current generates a potential difference according to the position of the body. Therefore, this potential difference can be measured and recorded through an electrode attached to the skin of the human body, and at this time, it is an electrocardiogram that is measured and recorded in this way.

The electrocardiogram is generally used as a basic method to check the presence of abnormalities in the heart and to measure diseases of the heart disease system such as angina, myocardial infarction, and arrhythmia.

On the other hand, in recent years, portable ECG measuring devices have been developed so that the above-described ECG can be naturally measured anytime, anywhere.

There are currently several methods of portable ECG measuring devices, and among them, the most well-known one is Holter ECG measurement, a test that performs analysis after recording for more than 24 hours during daily activities by attaching an electrode to the chest and connecting it to a portable recorder. In addition to Korean Patent Application No. 1986-0002744 (portable ECG recorder), registration number 10-0548967 (holter device) and registration number 10-0356421 (portable ECG measuring device) are disclosed.

However, the electrocardiogram measuring device according to the prior art is not widely used because of inconvenience, inconvenience, and expensive cost in use in general to be applied to all patients. Moreover, if there is no specific symptom within 24 hours, it becomes useless or has a major disadvantage that it must be used for an extended period of time until symptom onset is detected.

Therefore, by actually exercising in the hospital, an artificial load is provided to the heart, and an exercise load test, which detects the ECG waveform at that time and checks whether abnormalities appear in the heart, is used. This is not only uncomfortable, but also the ECG is abnormal. Is that it may not appear.

After all, there is a need for a device that is always carried by the general public in a simple way, and can measure and store the ECG directly during daily life, before and after exercise, or when abnormalities appear. The electrocardiogram for such a routine self-examination is to detect the electrocardiogram by touching the electrodes to the hands or feet only when necessary, even if all electrodes are not attached to the chest.

As a related patent, there is registration number 10-0356421 (portable electrocardiogram measuring device), which is restricted to the measurement location and is not suitable for carrying around because the area in contact with the electrode must use both hands and feet. .

The present invention has been proposed to solve the above technical problems, and provides a portable body composition measuring device capable of managing personal health by measuring and analyzing body composition and electrocardiogram from time to time in daily life because it is portable.

In addition, it provides a portable body composition measuring device capable of measuring not only electrocardiogram, but also body composition information.
