SEISMIC CARDIOBLOCK AND METHOD OF MEASUREMENT OF SEISMIC CARDIOCYCLE

FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment. Seismic cardio block contains a housing with a three-axis block of micromechanical accelerometers placed in it, a triaxial micromechanical gyro unit and a data processing and transmission scheme. Data processing and transmission scheme contains a secondary power source with a voltage stabilizer, a block of buffer repeaters based on low-noise operational amplifiers, a digital microcontroller (DM) with integrated analog-to-digital converter (ADC), interfaces and technological connector for programming the DM, as well as a microcircuit - a converter of the output interface with the main connector of the seismic cardioblock. Three outputs corresponding to the axes of the triaxial block of micromechanical accelerometers are connected to the ADC inputs via operational amplifiers, three outputs corresponding to the axes of the three-axis block of micromechanical gyroscopes are connected to other inputs of the DM, the output of the secondary power source is connected to the inputs of the corresponding operational amplifiers, to the input of a three-axis micromechanical accelerometer unit, to the input of the DM and to the input of the output interface converter. Output of the voltage regulator is connected to the input of the triaxial block of micromechanical gyroscopes and the input of the DM. DM is made with the possibility of digital-analog conversion of the received signals, filtering them and calculating the module of the vector of self-acceleration of the heart and the angles of its orientation in the instrument coordinate system for subsequent control of the human condition. Method for measuring the vector of self-acceleration of the heart is disclosed.EFFECT: technical result consists in increasing the reliability of diagnostics by reducing the measurement error, determining the orientation of the heartbeat acceleration vector relative to the human body.2 cl, 4 dwg Группа изобретений относится к медицинской технике.
