The present invention relates to a portable blood pressure measuring apparatus and method, and more particularly, to a portable blood pressure measuring apparatus and method capable of measuring a blood pressure value of a wrist or a finger artery corresponding to a blood pressure value of the brachial artery.To accomplish this, a finger-wearing type blood pressure measuring apparatus includes a blood pressure measuring unit for measuring a blood pressure of a finger artery on which the device is mounted by applying pressure to a cuff of the device surrounding the finger A pulse wave signal measured from the optical sensor part mounted in the cuff so that the finger artery is located between the photosensor parts in the cuff surrounding the finger, and a pulse wave signal measured from the electrocardiogram electrode part mounted inside the cuff and outside the cuff A pulse wave transmission rate measuring unit for measuring a pulse wave transmission rate of the finger using the measured electrocardiogram signal And a control unit for controlling the blood pressure value of the finger artery to at least a first constant and the pulse wave transmission rate so as to correct the blood pressure value of the finger artery measured by the blood pressure measuring unit to correspond to the blood pressure value of the brachial artery Wherein the first constant is a constant for correcting the blood pressure value of the finger artery in the blood pressure value of the finger artery and the pulse wave transmission speed is multiplied by a second constant for correcting the blood pressure value of the finger artery, Is added to the blood pressure value.본 발명은 휴대용 혈압측정 장치 및 방법에 관한 것으로, 특히 상완 동맥의 혈압 값과 대응되는 손목 또는 손가락 동맥의 혈압 값을 측정할 수 있는 휴대용 혈압측정 장치 및 방법에 관한 것이다.이를 달성하기 위해 손가락 착용 형 혈압측정 장치는, 손가락을 감싸는 상기 장치의 커프에 압력을 가함으로써 상기 장치가 장착된 손가락 동맥의 혈압을 측정하는 혈압 측정부 상기 손가락을 감싸는 커프 내에서 상기 손가락 동맥이 광 센서부 사이에 위치하도록 상기 커프 내에 장착되는 상기 광 센서부로부터 측정되는 맥파 신호와, 상기 커프의 내부 및 상기 커프의 외부에 장착되는 심전도 전극부로부터 측정
