Problems solved by technology

However, the adhesive plaster used has poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive plaster, so it will soak the damaged skin, making the wound and the skin around the wound whitish and soft, resulting in the secondary infection of bacteria. Infection which exacerbates wound deterioration
In addition, during the wound healing process, granulation tissue will slowly grow towards the center of the adhesive plaster, causing the adhesive plaster to closely adhere to the new tissue, which is difficult to remove, and causes tearing of the new tissue, and may even make the wound aggravate, increase the patient's suffering
In addition, sticking strips of adhesive plaster on the affected area affects the appearance, and many trauma wounds are irregular, and the trauma is not convenient to use in some specific parts
