Medical dressing has become one of the stock medicines in daily life, is often used in emergency care when minor wounds occur, is used for stopping bleeding and disinfecting and protecting wounds, and simultaneously isolates bacterial pollution in the environment. Common dressings are typically composed of a release layer, an adhesive layer, typically a waterproof film structure, an absorbent layer, typically a drug impregnated gauze structure, and a protective layer, typically a waterproof tape or a completely adhesive coated structure. When the traditional dressing is used, the air permeability is often poor, so that the skin at the wound dressing position is watered, the wound healing is not facilitated, and the wound healing condition cannot be checked in time. Meanwhile, the absorbing layer with ointment in the traditional dressing is directly contacted with the wound, is easy to adhere to the wound, and is easy to tear the healed wound again.

Patent CN204840393U discloses a visual wound-protecting dressing comprising an adhesive layer, an absorbent layer, a release layer.
