Description

technical field

[0001] The invention relates to the field of medical material fabric structure, in particular to a medical composite dressing. Background technique

[0002] As a covering for wounds, medical dressings can replace damaged skin to act as a temporary barrier during wound healing, avoid or control wound infection, and provide an environment conducive to wound healing. Nowadays, the market value of medical dressings is becoming more and more important, but the shortcomings of existing medical dressings are also very prominent: such as poor waterproof performance of dressings, once water enters, dressings need to be replaced, and frequent dressing changes are not conducive to wound healing The ventilation effect is not good, so that the comfort is not high; the amount of drug layer soaked in the drug layer is small, and the dressing needs to be replaced frequently; Tight, causing pain when changing the dressing and in severe cases can damage the new tissue.
