A recently granted patent (Publication Number: US11944521B2) discloses a unique composition designed for application to wounds. The composition comprises multiple layers, including a first layer with a low water absorption skin adhesive, apertures for wound contact, and a second layer made of a polymeric film with a high moisture vapor transmission rate. Additionally, a third layer acts as a supporting layer for the first layer, while a fourth layer contains adhesive and corresponding apertures. The arrangement of layers and apertures aims to provide effective wound care while maintaining transparency for monitoring purposes.

Furthermore, the patent details a method for forming the composition, involving the creation of apertures in the layers and the assembly of the different components. The skin adhesive used in the composition can be selected from various substances such as silicone, hydrocolloid, polyurethane, acrylic polymer, rubber adhesive, or hydrogel. The design of the composition ensures optimal functionality for wound healing and management, with specific requirements for the size and arrangement of apertures, as well as the characteristics of the adhesive and polymeric film layers. The patent emphasizes the importance of maintaining a balance between water absorption, moisture vapor transmission, and transparency in wound care products.
