Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a moisturizing and breathable medical dressing and a preparation method thereof. Background technique [0002] Medical dressings are a class of clinical medical materials that temporarily cover wounds such as burns, ulcers, and trauma. objects, collisions, inflammation, etc.), resist pollution and chemical stimuli; prevent secondary infection; prevent dryness and fluid loss (electrolyte loss); prevent heat loss; actively affect the wound healing process through debridement, creating a microenvironment that promotes wound healing. During the use of medical dressings, with the increase of time, the moisture retention decreases and the wound healing speed slows down. At the same time, due to the complex environment, it is easy to cause bacteria to grow; Ineffective. Contents of the invention [0003] Purpose of the invention: In order to overcome the above problems, one ...
