This invention discloses an arterial puncture hemostasis composite dressing and its preparation method. The dressing is prepared through electrospinning, impregnation, foaming, and lamination to obtain an outer protective layer, an adaptive pressure layer, and a skin-adhesive hemostasis layer arranged sequentially from top to bottom. The skin-adhesive hemostasis layer has a polysaccharide-based composite fiber structure, loaded with procoagulant, adhesive, and antifibrinolytic components, forming an adhesive gel layer upon contact with blood. The adaptive pressure layer is an elastic porous material layer containing liquid-absorbing and swelling particles that expand in volume after absorbing blood or body fluids, generating dynamic pressure. The outer protective layer is a transparent, breathable, and waterproof polyurethane membrane. The skin-adhesive hemostasis layer maintains liquid permeability, allowing some blood to be transferred to the adaptive pressure layer to trigger expansion. This invention achieves rapid and stable hemostasis through the synergistic effects of procoagulant, adhesive, and antifibrinolytic properties, as well as the adaptive pressure mechanism, making it particularly suitable for patients undergoing anticoagulation therapy.
