Investor has been granted a patent for a medical dressing designed to prevent pressure ulcers. The dressing features a backing layer, a pad, and a body contact layer with an adhesive and an anisotropic layer, which is stiffer in one direction to reduce shear and compression forces on the skin.

Medical dressing for preventing pressure ulcers
The patent US12059326B2 describes a medical dressing designed to enhance skin protection and reduce the risk of pressure ulcers. The dressing consists of three primary components: a backing layer, a pad, and a body contact layer. The pad is positioned between the backing and body contact layers, with both layers extending beyond the pad's edges to create a border. A notable feature of the body contact layer is its anisotropic layer, which exhibits different stiffness properties in two perpendicular directions. Specifically, the layer is significantly stiffer in the vertical (y) direction compared to the horizontal (x) direction, with a tensile force at 15% strain in the y direction being at least six times greater than in the x direction, as per ASTM D882-12 testing standards.
Additional claims detail variations of the medical dressing, including the incorporation of a plastic film, which may be made of polyurethane, and the presence of apertures in the body contact layer. These apertures can take the form of elongated cuts or openings aligned with the stiffer y direction. The dressing may also feature a second anisotropic layer with similar stiffness characteristics, and the adhesive skin contact layer can include silicone gel. Furthermore, the design allows for the inclusion of gripping tabs that extend outward from the border, facilitating application. The patent also outlines a method for applying the dressing to areas at risk of pressure ulcers, thereby aiming to mitigate the development of such conditions.
