DEVICE FOR MEASURING BIOLOGICAL POINT ACTIVITY Russian patent published in 2020 - IPC A61B5/53 A61H39/02 

FIELD: medicine.

SUBSTANCE: invention refers to devices for reflexotherapy, and is intended for examination of body state by analyzing electrophysiological signals. A biological point activity measurement device comprises a main power supply unit, a measurement unit, a biological point search unit, a meter, a switch, active and passive electrodes. Measurement unit includes a reference voltage source U₀ connected to the active electrode and, through a reference resistance R₀, with a passive electrode, with follower connected to logarithmic characteristic logger consisting of logarithmic steepness and initial offset and logarithmic nonlinearity amplifier, output of which is connected through an adder amplifier to a meter, and a voltage divider on resistors to obtain a test voltage connected through a reference voltage inverter to an adder amplifier. Biological point search unit is configured to individually adjust the search sensitivity threshold and includes a resistance measurement bridge, connected by arms to active electrode and, through switch, with passive electrode connected to threshold comparator, which output is connected to search availability light indicator and waiting multivibrator connected to audio signal indicator.

EFFECT: technical result of invention is higher accuracy and reliability of biological point activity measurement.
