The first measurement unit 41 includes an amplifier that amplifies the output electrode signal and an analog-to-digital converter that converts the analog signal into a digital signal and can measure the electrode signal. . For reference, the first measurement unit 41 may vary the size of the current supplied to the electrode unit, the current supply method, and the current measurement method depending on which mode it operates in: the body composition measurement mode or the electrocardiogram measurement mode. In other words, the first measurement unit 41 can measure body composition and electrocardiogram using the electrode unit 20, but adjusts the current supplied to the electrode unit 20 depending on each measurement mode or simply adjusts the current supplied to the electrode unit.

Impedance can be corrected. The body composition analysis module 45 can analyze body composition using electrode signals and a built-in body composition analysis program. The electrode signal refers to the current value, voltage value, and impedance value measured through the electrode unit 20.

The ECG analysis module 47 calculates ECG information using electrode signals (ECG signals). The electrocardiogram analysis module 47 determines the difference between action current and action potential due to contraction of the heart. The heart is a pump that circulates blood throughout the body and regularly repeats contraction and expansion. The pumping action of the heart is achieved by contraction of the myocardium. Each time the heart beats, a weak amount of electricity is generated, which causes an electric current to flow within the body, and this current generates a distribution of electric potential on the surface of the body. An electrocardiogram (ECG) is an electrocardiogram (ECG) that induces, amplifies, and records small electrical potential changes resulting from heart activity in an appropriate area of the body surface using a certain method. The ECG analysis module 47 identifies P, Q, R, S, and T waves, which are electrocardiogram waveforms that reflect the electrical activation stage of the heart. The P wave occurs during atrial depolarization, the QRS complex reflects ventricular depolarization, and the T wave reflects ventricular repolarization. This ECG analysis module 47 can analyze the presence of heart disease by identifying the pattern of the ECG waveform.

The storage unit 50 stores body composition and electrocardiogram information measured under the control of the first control unit 40, and may store an application that measures electrocardiogram and body composition such as body fat by a bioelectrical impedance measurement method. Additionally, information may be stored in the form of a graph or table representing body composition and electrocardiogram measured in time series.

In addition, the external terminal 70 is installed with an application to control the bio-signal measurement device 100, and the application receives, stores, and manages body composition information and electrocardiogram information from the bio-signal measurement device 100. In particular, the application can operate to automatically identify each user based on body composition information and electrocardiogram information and manage each user. Since unique body composition information and electrocardiogram information are extracted for each user, this can be used to identify the user.

The first light detection unit 430 is a component corresponding to the light receiving unit 313 described in FIGS. 4 and 5, includes a light receiving element such as a photodiode, and detects the light emitted from the first light source unit 410. After being irradiated to an object (eg, a finger), the light passing through the object may be converted into a current signal and then transmitted to the second measuring unit 471.

The second light source unit 440 is a component corresponding to the first light emitter 355a and the second light emitter 355b described in FIGS. 6 and 7 for measuring advanced glycation end products, and projects light of different wavelength bands. It may include a plurality of light sources.

The second driving unit 450 controls a plurality of light sources constituting the second light source unit 440, and for this purpose, the second light source unit 440 can be driven based on a timing control signal from the second control unit 470. .

The second light detector 460 is a component corresponding to the first light receiver 313a and the second light receiver 313b described in FIGS. 6 and 7, and the light emitted from the second light source unit 440 is transmitted to the object (e.g. , finger), it may include a light receiving element capable of detecting two different wavelengths of a fluorescence signal and a transmitted light signal from the transmitted light.

The second control unit 470 may include a second measurement unit 471, an oxygen saturation measurement module 473, and an advanced glycation end product measurement module 475.

The second measuring unit 471 can measure the current signal and optical signal for the received transmitted light by irradiating the light emitted from the first light source unit 410 and the second light source unit 440, respectively, to the user's body. Specifically, when the user's finger is positioned on the first light source unit 410 and the second light source unit 440, the second measurement unit 471 measures the light emitted from the first light source unit 410 and the second light source unit 440. Measure the current signal and optical signal for light emitted from the finger, that is, transmitted light. At this time, the second measurement unit 471 is an amplifier that amplifies the current signal or optical signal output from the first and second light detection units 430 and 460, and an analog signal that converts the analog signal into a digital signal. -Can measure current signals and optical signals, including a digital converter (analog-to-digital converter).

The oxygen saturation measurement module 473 converts the current signal for the transmitted light having different wavelengths detected by the first light detector 430 into a voltage signal, and then generates voltage signals corresponding to the transmitted light having different wavelengths. After separation, the AC and DC components of the separated voltage signals are extracted, and oxygen saturation is calculated using this. At this time, the oxygen saturation value can be calculated using a known oxygen saturation measurement algorithm such as Beer-Lambert Law. Oxygen saturation (SpO2) (%) is calculated as “oxygen-bound hemoglobin/total hemoglobin (oxygen-bound Hb + oxygen-unbound Hb) * 100(%).” In other words, hemoglobin in red blood cells can be divided into whether or not it is combined with oxygen. If it is combined with oxygen, it can be called Oxygenated Hemoglobin (OxyHb). If it cannot bind to oxygen, it can be called Deoxygenated Hemoglobin (DeoxyHb). Hb bound to oxygen (OxyHb) and oxygen Hb (DeoxyHb) that is not combined with has a different degree of absorption of light (e.g., infrared) in different wavelength regions (i.e., the light absorption coefficient of hemoglobin is different), and using this principle, the embodiments of the present invention and Likewise, oxygen saturation (SpO2) can be measured by projecting a plurality of lights (e.g., infrared rays) with different wavelengths onto an object.

The advanced glycation end product measurement module 475 calculates the advanced glycation end product using the optical signal detected from the subject. Advanced Glycation End products (AGE) are formed in the oxidation of proteins in body organs as a result of the Maillard reaction. These reactions impair many protein functions. Oxidative stress increases rapidly due to acute diseases such as sepsis, as well as exposure to cardiac risk factors such as smoking, a diet containing high fatty acids, or hypercholesterolemia. Accordingly, advanced glycation end products (AGE) are generated. These advanced glycation end products (AGEs) decompose and accumulate slowly over time. An increase in advanced glycation end products (AGE) is associated with the progression of chronic diseases such as atherosclerosis, and tends to accumulate in the body as a person ages.

When hyperglycemia persists, non-enzymatic protein glycation and oxidation continue to occur, resulting in the formation of advanced glycation end products (AGE), an irreversible complex of sugar and protein. In people suffering from diseases of the vascular system such as diabetes, renal failure, and cardiovascular disease, the accumulation of advanced glycation end products (AGEs) progresses quite quickly. Advanced glycation end products (AGE) products accumulate in various tissues, including the skin. Advanced glycation end products (AGE) have the property of emitting autofluorescence (AF) in the blue spectral region (maximum near 440 nm) upon irradiation with excitation light in the ultraviolet region (maximum near 370 nm). Examples according to the present invention measure advanced glycation end products using autofluorescence, that is, optical signals.

The storage unit 50 stores oxygen saturation and advanced glycation end products information measured under the control of the second control unit 470, and may store an application for calculating oxygen saturation and advanced glycation end products. Additionally, information can be stored in the form of a graph or table showing oxygen saturation and advanced glycation end products measured in time series.

The communication module 60 exchanges data with an external terminal wired or wirelessly, and provides various communications such as Bluetooth, Zigbee, near field communication (NFC), and wireless-fidelity (Wi-Fi). Can contain modules.

The display unit 560 displays the measured oxygen saturation value, and divides the oxygen saturation value into a normal group when the oxygen saturation value is 95% or more, a case where the oxygen saturation value is 91% to 94%, a case where the oxygen saturation value is 81% to 90%, and a case where it is 80% or less. It can be separated into caution group, risk group, and high risk group.
