Description

a hydrogel dressing

technical field

The utility model relates to a hydrogel dressing, which is especially suitable for a hydrogel dressing product with a three-dimensional structure.

Background technique

With the improvement of the precision of medical equipment and instruments, and the continuous improvement of human knowledge, the wet healing theory of wounds has been accepted by the majority of medical workers and patients. Providing a moist healing environment for the wound is a functional dressing that promotes wound healing. Although this type of dressing can actively promote the healing of the wound, there are also some problems, such as: alginate, polyvinyl alcohol and other materials are used as dressings. Dressings with functional components provide a slightly humid environment to promote wound healing by passively absorbing wound exudate. , the above-mentioned dressings cannot actively provide a moist healing environment; dressings with hydrogel sheets as functional components can actively provide a moist healing environment, but in the process of nursing wounds such as channels and depressions, such dressings cannot be used on wounds. Sufficient contact will result in a large amount of exudate remaining in the space formed by the dressing in the wound, causing the wound to be easily infected and not conducive to healing; in addition, as the dressing product is used for a long time, the edge becomes dry and hard, causing pain, Itching and other stimuli affect the patient's treatment experience and the quality of wound healing.
