Blood absorption improvement of a naturally derived hemostatic agent by atmospheric pressure plasma jet

Abstract Hemostatic capability improvement of a chitosan hemostatic agent was achieved by surface modification using the atmospheric pressure plasma jet experiment. The chitosan hemostatic agent acquired high blood absorption rate, at 4.60 ml/m, when exposed to input power 10 W of the radiofrequency power supply, the argon flow rate of 4 L/m mixture with an oxygen gas of 10 ml/m, and treatment time of 30 s. A significant decreased was observed in the hemoglobin leak value, inducing early blood clotting ability of clotting in 30 s. The strong relation of gas plasma discharge with the OH radical and the atomic oxygen, exhibited an increase in the hydrophilic properties, which lead to the chitosan hemostatic agent being very effective.
