‎The aim of this research was determination of the required time for coagulation of in vivo cut bleeding treated by non-thermal atmospheric pressure plasma‎. ‎To meet this‎, ‎an atmospheric pressure plasma jet device was designed and constructed‎. ‎Helium was used as working gas‎. ‎The electrical parameters and optical emission spectrum of helium plasma were measured‎. ‎The averaged treatment time to coagulate the incision bleeding on the mouse liver was obtained 8.6 μs‎, ‎and the average time of naturally incision bleeding coagulation was 10 min‎.


  • The coagulation time of in vivo bleeding treated by cold atmospheric pressure plasma was determined.
  • The optical emission spectrum of plasma showed the existance of ROS and RNS species.
  • The coagulation time of treated cut was compared with control cut.
