The present invention relates to a biometric system using both hands for the evaluation of blood vessel and cardio pulmonary function, the system being capable of measuring an electrocardiogram, oxygen saturation, blood pressure, body impedance and performing tests on body fat percentage, non-invasive blood pressure (NIBP), vascular compliance, cardiac output and pulmonary function, in order to perform multi-dimensional analysis on the bio parameters rather than using a single parameter, and using just two hands, thus reducing cost and time restrictions and allowing continuous monitoring of blood vessel and cardio pulmonary function. A biometric system of the present invention is configured in that a blood pressure measuring cuff is placed around the wrist of a user, and a left end and a right end of the system can be held by the hand of the user, respectively, the left right ends having respective hand contact portions in which the respective bio signal detection electrodes are embedded, the system comprising: an electrocardiogram and body impedance measurement module serving as a means for measuring an electrocardiogram, body impedance, cardiac output and impedance pulmonary function and having an electrocardiogram sensor unit and a body impedance sensor unit for detecting an electrocardiogram signal and a body impedance signal in order to thus measure an electrocardiogram parameter including RR interval, FEV1/FVC ratio, cardiac output, body fat and vascular compliance; an oxygen saturation detection module having an oxygen saturation sensor unit for detecting oxygen saturation; a blood pressure measurement module having an NIBP sensor unit and a pressure sensor unit for detecting a blood pressure signal from the NIBP sensor unit and a Korotkoff sound signal from the pressure sensor unit in order to detect blood pressure from the blood pressure signal by means of an oscillometric method and detect blood pressure based on the Korotkoff sound from the Korotkoff sound signal; and a main module for controlling operations of the electrocardiogram and body impedance measurement module, the oxygen saturation detection module and the blood pressure measurement module, collecting statistics on the bio measurement signals of a user and outputting the result on a display unit. |
