Device and method for noninvasive measurement of blood pressure, resistance inertance, compliance, impedance, blood flow rate, kinetic energy, flow velocity and pulse velocity of a segment in man

摘要

A device for noninvasively measuring various parameters characteristic of a blood circulation system within a human being includes a volume measuring device secured to a specific part of the human being for measuring changes in the blood flow volume therethrough, and a pressure measuring device, also secured to the specific part and spaced from the volume measuring device a pre-determined distance, for measuring the changes in pressure within the specific body part. Transducers convert the sensed volume and pressure values into electrical signals which are transmitted to suitable recording means whereby such recorded values, which are functions of time, may be utilized for determining the desired parameters.
