The hemostatic device is a common first-aid device in field operation environment, and has irreplaceable functions in field medical rescue and rescuing. Most of the existing hemostatic devices used in field first-aid technology only use one state of hemostatic material, for example, the hemostatic material is used for hemostasis by pure liquid or pure powder material, the hemostatic variability is small, and the hemostatic device can not achieve timely and definite hemostasis for injuries under some conditions. Because of poor fluidity, the powder is difficult to completely fill in narrow bullet hole injuries and deep bleeding, and is mostly white powder, and the deep bleeding stopping effect is difficult to judge after the powder is used; the gel preparation is difficult to rapidly coat on extensive body surface bleeding, prolongs bleeding time and influences the treatment of wounded. Because the wounded condition of a wounded person is complicated and various under the battlefield condition, the hemostatic device of single material is difficult to handle all problems, therefore, often need to use multiple hemostatic materials to different wounded conditions, this leads to very loaded down with trivial details when handling under the battlefield environment, can cause the increase of wounded person's hemorrhagic volume, prolongs the hemorrhagic time, increases certain degree of difficulty to the rescue of wounded person.
