DEVICE FOR MEASUREMENT OF BLOOD PARAMETERS Russian patent published in 2000 - IPC

FIELD: medical equipment, serves as a hematologic apparatus for direct measurement of blood parameters. SUBSTANCE: device has a flask, upper cover, lower cover, electric motor, electromagnets, shaped cylinder, flange with holes, teflon needles, thrust bearings, blades, direct light-emitting diode, reflected light-emitting diode, photodiode, microelectrode casing, microelectric illumination lamp, light conduit, shaped cylinder casing, shaped cylinder fastening rod, trap, microelectrode, inlet valve, outlet valve, filling opening, indicating unit, control unit, digital-to-analog converter (A/D), recording unit, digital-to analog converter amplifier unit, thermostated space, flask body. The device measures four blood, parameters: the time of spontaneous and inductive aggregation of blood formal elements in any media with possibility of analysis of the obtained aggregation curves; dynamic viscosity of blood and other fluids with possibility of analysis of the dynamics of its variation; blood optical density with possibility of conversion of the packed cell volume and other fluids with possibility of conversion of concentration; membrane potential of erythrocyte rest. EFFECT: enhanced capacity, accuracy and information completeness at direct, alternate measurement of four parameters of small quantity of blood in one flask. 5 dwg
