APPARATUS FOR CONTINUOUSLY AND AUTOMATICALLY MEASURING PULSE WAVE AND METHOD FOR MEASURING BLOOD PRESSURE

摘要

Disclosed is an apparatus for continuously and automatically measuring a pulse wave by a non-invasive method to know the state of a cardiovascular system. The apparatus includes an integrated measurement module, a communication power module, and a bio-measurement pad. The integrated measurement module includes an electrocardiogram measurement portion for measuring the electrocardiogram of a subject, a bioelectrical impedance measurement portion for measuring the bioelectrical impedance of the subject by a potential difference, a heart sound measurement portion for measuring the heart sound of the subject, and a controller for measuring and controlling the state of the cardiovascular system of the subject on the basis of a pulse transit time calculated by the electrocardiogram signal measured at the electrocardiogram measurement portion, the bioelectrical impedance signal measured at the bioelectrical impedance measurement portion, and the heart sound signal measured at the heart sound measurement portion.

1. An apparatus for measuring a pulse wave continuously and automatically, comprising:
an integrated measurement module comprising an electrocardiogram measurement unit which measures electrocardiogram of a testee, a bioelectrical impedance measurement unit which measures bioelectrical impedance of the testee based on a potential difference, a cardiac sound measurement unit which measures a cardiac sound of the testee, and a controller which measures a state of a cardiovascular system of the testee based on a pulse transit time (PTT′) calculated based on the electrocardiogram signal measured by the electrocardiogram measurement unit, the bioelectrical impedance signal measured by the bioelectrical impedance measurement unit, and the cardiac sound signal measured by the cardiac sound measurement unit; a first communication power module comprising a first wireless communication unit which is electrically connected to the integrated measurement module and wirelessly sends and receives information of the integrated measurement module and information of an external terminal and a first power supply unit which supplies power to the first wireless communication unit and the measurement module; and a biomeasurement pad in which the integrated measurement module and the first communication power module are seated and which comprises bioelectrodes electrically connected to the bioelectrical impedance measurement unit.
