DEVICE FOR CARRYING OUT ETIOLOGICAL DIAGNOSTICS AND TESTING LIVING OBJECTS WITH MEDICAL PREPARATIONS Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: device has a power supply source provided with a current stabilizer, an electrode unit having indifferent and searching electrodes with a connector to connect testing members and an electric conductivity measuring unit, a voltage pattern bipolar source, a commutator, a summing converter unit. An additional electrode is introduced into the electrode unit structure, power supply source outputs being connected to voltage pattern source inputs, which bipolar outputs are connected to the first summing converter unit input through the commutator. The summing converter unit output is connected to the electrode unit indifferent electrode and the second input is connected to the additional electrode. EFFECT: enhanced effectiveness in reducing disturbance level in measuring electric skin conductivity; enhanced sensitivity of measuring device; reduced traumatic injuries; enhanced reliability of diagnosis. 3 cl, 2 dwg
