NONINVASIVE METHOD AND DEVICE FOR DETERMINING HEMODYNAMIC PARAMETERS IN BIOLOGICAL OBJECTS Russian patent published in 1999 - IPC

Abstract RU 2127999 C1

FIELD: hematology. SUBSTANCE: invention can be, for example, used to determine minute circulatory volume, heart beat volume, heart beat frequency, etc. Pulse pressure wave is chosen as analytical signal reflecting hemodynamic parameters. Pulsogram is recorded, for example, on ear lobe. A number of pulse wave parameters is analyzed taking into consideration anthropometric data (e. g. , height, arm span). Minute circulatory volume and other hemodynamic parameters are computed using math formulas provided. Method is implemented using device containing units measuring parameters associated with displacement of blood in bioobjects, parameter- treatment units, and hemodynamic parameter-determination processor interrelated into original flowchart. EFFECT: accelerated procedure and enabled long-term continuous monitoring of parameters of interest. 2 cl, 2 dwg
