US Patent 10960205 Electric treatment device and treatment system

An electric treatment device includes an impedance detector to measure bioelectrical impedance at a site of a body of a user by using electrodes in contact with the site, a voltage controller to perform treatment of the site by controlling a voltage applied to the electrodes, and a timer to set a target time from when treatment of the site is started by the voltage controller to when the voltage value of the applied voltage reaches the target voltage value, based on the measured bioelectrical impedance. The greater the measured bioelectrical impedance is, the shorter the timer sets the target time. The voltage controller increases the voltage value of the applied voltage to the target voltage value based on the set target time.
