Problems solved by technology

[0002] In the field of medical care products, 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 invasion of dirt from causing infection. The material is easy to cause gauze to adhere to the wound. At present, needle-punched non-woven composite isolation film is used to solve the problem of adhesion to the wound. However, this anti-adhesion material has certain limitations. Generally speaking, the isolation film is made of PE material. The process of pulling and tearing the mesh is solved, the process is difficult, the cost is high, and the mesh spacing is large, which affects the absorption effect of the absorbent layer material. Therefore, we propose a rapid prototyping manufacturing process for medical isolation film materials to solve the above problems.
