Tumor electric field therapy system and electric field application method thereof

Abstract

The application provides a tumor electric field treatment system, which comprises an electric field treatment instrument and at least two pairs of insulated electrodes of the treatment instrument, wherein the electric field treatment instrument comprises an MCU control unit, a direction control unit, a DC power supply control unit and an AC voltage control unit. The MCU control unit is configured to control the AC voltage control unit to output an alternating electric signal according to system parameters of the electric field treatment instrument. The MCU control unit is further configured to drive the direction control unit to cyclically and alternately apply the alternating electric signal received by the AC voltage control unit to different pairs of insulated electrodes based on the system parameters of the electric field treatment instrument, so as to realize switching of the alternating electric signal between the different pairs of insulated electrodes. The MCU control unit is further configured to control the DC power supply control unit to make the AC voltage control unit slowly rise or slowly drop at a voltage change amount set in a unit time t when the alternating electric signal is switched between the different pairs of insulated electrodes.
