Medical dressing for contoured surface with high tensile strength
A newly granted patent (Publication Number: US11957547B2) describes a unique medical dressing designed for application to contoured surfaces of the human body. The dressing features a central portion and a surrounding border portion, with a multi-layered pad arranged between a backing layer and an adhesive body contact layer. The pad consists of at least three layers, including a first layer with a higher liquid affinity than a second layer, and a third layer made of polyurethane foam. The dressing is symmetrical about a longitudinal center line and includes lobed portions on either side of the center line. The central portion of the dressing exhibits a higher tensile strength in the longitudinal direction compared to the lateral direction, making it stiffer in one direction and more stretchable in the other.
Additionally, the patent includes claims for various features of the medical dressing, such as the inclusion of gripping tabs, specific tensile strength requirements for different portions of the dressing, and the composition of the adhesive body contact layer. The dressing is designed to be more stretchable in the lateral direction, corresponding to a direction perpendicular to the spine of a patient. The use of specific materials, such as a polyurethane film and a silicone gel adhesive layer, ensures the effectiveness and comfort of the dressing when applied to contoured surfaces of the body. Overall, the patented medical dressing offers a unique and innovative solution for addressing the challenges of applying dressings to complex body surfaces, providing both functionality and comfort for patients.
