Problems solved by technology

[0002] Medical dressings are medical materials used to cover wounds or other damages. The traditional way to deal with wounds is mainly to cover them with gauze to absorb the exudate of the wound surface and prevent the intrusion of dirt from causing infection. However, this method cannot moisturize and Adhesive wound surface, it is easy to damage the wound again when changing, causing severe pain
There are some dressings made with new materials and new methods, but none of them use all-natural absorbable materials that are safe and reliable
