Patent number: 11457522Abstract: The present invention relates to a skin treatment apparatus using plasma. A plasma generator (400) comprises an electrode plate (420), an upper dielectric body (430), independent electrode portions (440) and a lower dielectric body (450). The independent electrode portion is an FPCB or a silver paste positioned a fixed distance away. According to the present invention, the electrode portions each independently work and thus prevent unevenness of plasma and enable the plasma to be generated evenly. According to the present invention, the plasma generator having such configuration is easily formed into a convex shape, and a convex plasma generator is suitable for a curved skin object such as the palm. The convex plasma generator can generate more even plasma and is particularly more effective for a long cylindrical object to be treated, such as the woman's vagina.Type: GrantFiled: September 10, 2018Date of Patent: September 27, 2022Assignee: SEOULIN MEDICARE CO., LTD.Inventor: Byoung Choul Kim

Patent number: 11433250Abstract: The present invention relates to a skin treatment apparatus using plasma, in which a plasma generator includes an electrode plate an upper dielectric body independent electrode parts and a lower dielectric body. The independent electrode parts are a plurality of pieces of silver paste or flexible printed circuit boards (FPCBs) which are spaced a certain distance apart from each other. According to the present invention, electrode parts operate independently to prevent a plasma concentration phenomenon and uniformly generate plasma. According to the present invention, a plasma generator configured as described above is easy to form in a convex shape, and a convex plasma generator is applicable to a curved region of the skin to be treated, e.g., a palm. Furthermore, the convex plasma generator is capable of more uniformly generating plasma and is particularly effective for treatment of a long and round cylindrical object to be treated, e.g., the vagina of a woman.Type: GrantFiled: February 1, 2018Date of Patent: September 6, 2022Assignee: SEOULIN MEDICARE CO., LTD.Inventor: Byoung Choul Kim
