Fractional microneedle hybrid switch module manufacturing method

Abstract

Proposed is a fractional microneedle hybrid switch module manufacturing method capable of uniformly distributing high-frequency energy to a portion of the skin and a local site to be treated by partitioning a fractional microneedle patch and applying a high-frequency signal to needles in the partitioned zones, and an electrically isolated switching element is attached to each of partitioned zones so that energy may be efficiently injected, and stable control that can prevent malfunctions due to noise caused by high frequency is possible.

1 . A fractional microneedle hybrid switch module manufacturing method comprising:
 generating a flat plate made of a conductive material;   partitioning the flat plate having conductivity into m×m parts to generate N partitioned zones;   generating M grooves into which fractional microneedles are inserted in the N partitioned zones and inserting M fractional microneedles into the grooves;   connecting each of the M needles inserted into the N partitioned zones with an electrical connection terminal such that a high-frequency signal is applied thereto; and   applying high-frequency energy applied to the microneedle to a portion of the skin or a local site using monopolar and bipolar hybrid switch modules.   
     
     
         2 . The method of  claim 1 , comprising:
 configuring the hybrid switch module including an input needle connected to a switch that is connected to a counter electrode (human body), and an output needle connected to the electrical connection terminal and configured to supply power; and   configuring the hybrid switch module in a monopolar or bipolar type depending on a connection type by which the input needle is connected to the counter electrode or the electrical connection terminal.   
     
     
         3 . The method of  claim 2 , comprising selecting the monopolar type or the bipolar type of the hybrid switch module according to a skin condition of a person and a site to be treated. 
     
     
         4 . The method of  claim 3 , comprising configuring the hybrid switch module in the monopolar type by connecting the switch connected to the counter electrode to a switch of the input needle and connecting a switch of the electrical connection terminal to the output needle when targeting and healing a portion of the skin of the person; and
 configuring the hybrid switch module in the bipolar type by connecting the output needle and the switch of the input needle to the switch of the electrical connection terminal when targeting and healing a local site of the skin of a user.   
     
     
         5 . The method of  claim 4 , further comprising forming a ground for each needle itself, to which the hybrid switch module configured in the bipolar type is connected.
