Abstract:
본 발명은 모든 피측정자들에게 공통적으로 적용 가능하게 혈관의 탄성도를 측정할 수 있는 혈압 측정 방법을 제공한다. 이를 위해 본 발명은 커프 압력 변화에 따라 맥파 전달 시간이 달라진다는 점을 이용하여, 압력을 가하지 않았을 때의 맥파 전달 시간을 산출하고, 커프에 의해 압력이 변화하는 구간에서의 맥파 전달 시간을 산출한 후, 그 맥파 전달 시간들을 이용하여 혈관의 탄성도를 구하는 과정으로 이루어진다. 이와 같이 혈관의 탄성도와 관련된 맥파 전달 시간을 이용함으로써 혈압이나 개인 편차와 무관한 절대적인 지표로 사용할 수 있는 혈관의 탄성도를 구할 수 있게 된다. 혈압, PTT, 탄성도

PURPOSE: An apparatus and a method of measuring a blood pressure for measuring blood vessel tension are provided to implement the convenience of a subject by measuring the blood pressure and blood vessel tension at the same time. CONSTITUTION: In an apparatus and a method of measuring a blood pressure for measuring blood vessel tension, a pulse wave transfer speed measurement module(500) measures the pulse wave transfer speed by using an electrocardiogram signal and a pulse signal. The pulse wave transfer speed measurement module includes a photoplethysmograph measurement module(540) and an electrocardiogram measurement module. A blood measurement module(505) increases and decreases pressure a curve to measure blood pressure. A blood pressure measurement module comprises a display unit(515), an air pump(520), a pressure sensor(525), an analog digital converter(530), and a valve adjust unit(535) A controller calculates blood vessel tension using an initial pulse wave transfer time and the pulse wave transfer time in a curve period.

A card type portable terminal for measuring a bio signal is provided to test a pulse wave and an electrocardiogram without going to hospital by using two electrodes and at least one photo sensor. A card type portable terminal includes an electrocardiogram electrode part(110), a sensor unit(120), a controller(130) and a wireless communications unit(140). An electrocardiogram electrode part includes a first electrode(113) and a second electrode(115). The first electrode is arranged in the front side of the body. The second electrode is arranged in the first side surface of the body. The electrocardiogram electrode part measures the electrocardiogram signal through the first electrode and the second electrode. The sensor unit is arranged in the second side of the body in order to measure the pulse wave signal. The controller is arranged inside the portable terminal. The controller analyzes the electrocardiogram signal and the pulse wave signal received from the electrocardiogram electrode part and the sensor unit. The wireless communication unit transmits the analyzed result by the control of the controller.
Abstract:
A method for analyzing the stress based on biometric signal measured multiple is provided to perform the quantitive administration of the stress by continuously measuring own stress. A plurality of SRI questions among SRI(Stress Response Inventory) questions stored in a memory is selected(110). The selected SRI questions and a plurality of choice points are displayed on a portable terminal(120). The response about SRI questions is received(130). The result of response is stored(140). The above steps are repetitively performed. The end state of the SRI response is determined(150). The bio-signal of the section is measured. The bio-signal measuring process waits until the next measurement duration(160). In the next section, the bio-signal is measured(170). The bio-signal pattern information including the pattern of the bio-signal measured for one cycle is generated(180). Discrete reference information including the bio-signal pattern information and SRI response are generated(190). The stress management server produces the reference information classified according to the standards(200).
Abstract:
A bio-information measuring system is provided to measure bio-information considering the influence of skin accurately by receiving basis bio-information from a user. An input unit(265) receives basis bio-information of a user. First to third light sources(220,230,240) are arranged on the surface of skin(276). The first light source irradiates the first light having a first wavelength in the surface of the skin. The second light source irradiates the second light having a second wavelength in the surface of the skin. The third light source is positioned further from an optical detector(210) than the first and the second light sources. The third light source irradiates the third light having a third wavelength in the surface of the skin. The optical detector successively detects first to third detecting lights penetrating the surface of the skin with electric signals. A controller(250) successively operates the first to third light sources. The controller produces bio-information of a user based on the intensities of the first to third detecting lights and the basis bio-information.
