The invention discloses a medical hemostatic dressing, a preparation method and its application. The medical hemostatic dressing provided by the present invention comprises the following raw materials in parts by weight: 0.5-2 parts of recombinant collagen, 1-5 parts of water-soluble high molecular polymers and 0.2-1 parts of moisture retaining agent. The medical hemostatic dressing provided by the invention has super water absorption and blood absorption, and the moisture absorption ratio is 50-300 times its own weight, which can effectively remove the liquid on the wound surface and has an obvious hemostatic effect on the bleeding wound surface. Due to the addition of a moisture retaining agent and a water-soluble polymer, the dressing surface is soft and smooth without adhesion, thereby avoiding secondary damage to the wound during hemostasis and wound cleaning. In addition, because the raw material used is recombinant collagen, its drug-carrying capacity is stronger, and the wound healing effect is obvious, and the medical hemostatic dressing is widely used, which can be used for hemostasis in surgery with a large amount of bleeding and removal of common wounds in daily life. and treatment, applicable to all periods of the wound. |
