A hemostatic dressing of application number CN201721797935.2 has been used to stop bleeding on puncture wounds, but the dressing does not have the effect of accelerating wound repair.

Hydrocolloid dressing is a dressing made by mixing elastic polymeric hydrogel with synthetic rubber and adhesive. The hydrocolloid dressing has the characteristic of absorbing wound surface seepage, and can form a closed wet environment around the wound after absorbing seepage, so that the capillary proliferation and the formation of granulation tissues can be promoted, and the healing of the wound surface is accelerated; in addition, hydrocolloid dressings have a debridement function, and various hydrocolloid dressings are currently used for wound management and care.
