DEVICE FOR BUILDING CARDIAC RHYTHMOGRAM Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has electrodes, main amplifier, filter unit, analog-to-digital converter, communication unit, signal analysis unit and power supply source connected in series. The device also has input amplifier, device for eliminating isoline drift and inphase signal compensator unit. One output of the input amplifier is connected to one of control inputs of the device for eliminating isoline drift and main amplifier input. The output of the device for eliminating isoline drift is connected to one of input amplifier inputs, two other inputs being connected to the electrodes placed on patient body, the other output of the input amplifier is connected to the inphase signal compensator unit input placed on the right patient leg. Accumulator battery units having power converters are used as power supply source. One of outputs of signal analysis unit is connected to the other control input of the device for eliminating isoline drift via communication unit. Acoustic signal and luminous signal units are connected to the accumulator battery units. EFFECT: wide range of functional applications. 2 cl, 2 dwg
