Title:
末梢循環状態監視装置
Document Type and Number:
Japanese Patent JP3602880
Kind Code:
B2
Abstract:
An apparatus for monitoring a peripheral blood-flow condition of a living subject by detecting a peripheral blood-flow resistance of the subject, including a first and a second pulse-wave sensor which are adapted to be worn on a first and a second portion of the subject, respectively, to detect a first and a second pulse wave, respectively, each of which is produced in synchronism with a heartbeat of the subject, a phase-difference determining device for determining a difference of respective phases of the first and second pulse waves detected by the first and second pulse-wave sensors, and a peripheral blood-flow resistance determining device for determining the peripheral blood-flow resistance of the subject, based on the phase difference determined by the phase-difference determining device, according to a predetermined relationship between peripheral blood-flow resistance and phase difference.
