FIELD: medicine.
SUBSTANCE: device comprises a safety circuit comprising a detection means to detect presence of a hazardous condition associated with an electric shock, a monostable multivibrator to drive a switching means to turn off a DC power source for a predetermined interruption duration upon detection of a hazardous condition associated with an electric shock, and subsequent cyclic reconnection and disconnection of the direct current source until the dangerous state is eliminated. The monostable multivibrator is designed to attempt to reconnect the DC power supply during the connection and shutdown cycle for a duration less than the predetermined interruption duration. The monostable multivibrator is also configured to restore a continuous supply of direct current to the said circuit prior to the next occurrence of a hazardous condition associated with an electric shock or until completion of the said procedure.
EFFECT: efficiency of ionization device control and level of surgical procedures safety are increased.
