DEVICE FOR MEASURING ELECTRICAL CONDUCTIVITY OF THE SKIN

摘要

The invention pertains to medical engineering and can be used for rapid diagnosis of the functional state of a human organism. The proposed device comprises a device for converting measured and reference conductivities into a pulse sequence whose on-off time ratio is proportional to the measured conductivity. The circuit includes means for protecting the measurement electrodes from pulse voltages. An opto-electronic unit is provided and the power source is designed as a computer serial port voltage inverter, with the primary and secondary windings on separate magnetic circuits which are interconnected by a short-circuited loop; these measures ensure electrical safety and reduce mutual interference between the device and computer.
