Concept and Classification of Medical Dressings:
Definition: A medical material used for bandaging surgical incisions or traumatic wounds.
Classification: Natural Materials (e.g., natural gauze, suitable for various types of wounds); Synthetic Polymer Materials (e.g., polymer-based medicated dressings, capable of providing antibacterial and analgesic effects); and Composite Materials (e.g., hydrocolloid dressings, primarily used for the treatment of chronic wounds such as pressure ulcers and venous ulcers).
Functions: To protect the wound, prevent infection and dehydration, create an environment conducive to wound healing, and promote the healing process.
Manufacturing Process: Requires strict aseptic control.
Functions: Covers the wound, absorbs exudate, promotes healing, and prevents infection; it protects the wound, maintains a moist environment, alleviates pain, and minimizes scar formation.
