Introduction to wound dressings

Wound dressings are materials used to bandage wounds and used to cover sores, wounds or other damages. The types of wound dressings are: 1. Passive dressings (traditional dressings), which passively cover the wound surface and absorb exudate, providing limited protection for the wound surface. 2. Interaction dressings. There are many forms of interactions between dressings and wounds, such as absorbing exudate and toxic substances, allowing gas exchange, thereby creating an ideal environment for healing; barrier outer structure prevents Microorganisms invade the environment to prevent cross-infection of wounds, etc. 3. Biologically active dressing (closed dressing).
