    • RF energy for skin conditioning with a non-ablative electrode is applied with a handpiece incorporating means to prevent electrical shock to the patient when the energized electrode surface makes or breaks contact with the skin. In a preferred embodiment, switch means are incorporated in the handpiece and configured such that the active electrode surface is not energized until it is in actual contact with the patient's skin, and remains energized only while the active electrode surface remains in contact with the patient's skin, so that no voltage is present on the electrode, when an air gap whose dielectric breakdown can cause an electrical shock to the patient arises, immediately before or immediately after skin contact during a skin conditioning procedure. In another preferred embodiment, the electrode to skin impedance change as the electrode touches the skin is used to activate a switch that transfers RF to the electrode.
    • 用无消融电极进行皮肤调理的射频能量应用带有手段的手持件,用于在通电的电极表面与皮肤接触或断开接触时防止对患者的电击。 在优选实施例中,开关装置并入手持件中,并且构造成使得有效电极表面在与患者皮肤实际接触之前不通电,并且仅在活性电极表面保持与患者皮肤接触时保持通电 ,使得当在皮肤调理过程中紧接在皮肤接触之前或之后,当介电击穿可能对患者造成电击的气隙时,电极上不存在电压。 在另一个优选实施例中,电极与皮肤之间的阻抗随着电极接触皮肤而改变,用于激活将RF传送到电极的开关。
