Breathable prosthetic interface with vacuum suspension features
The granted patent US12036137B2 describes a prosthetic interface designed to enhance the connection between a residual limb and a prosthetic socket. The interface features a body portion with a proximal end that is open and a distal end that is closed. It is constructed from a flexible membrane component that creates an internal flow space, allowing for fluid transport between the skin surface of the limb and the outer side of the membrane. The design includes a distal cup made from a polymeric material and incorporates at least one selectively applied material coating. This coating establishes both a breathable region and an impermeable region, facilitating vacuum suspension between the prosthetic interface and the socket. The body portion also includes an elastomeric wall, with the membrane positioned radially inside this wall.
Further details of the prosthetic interface reveal that the membrane component has distinct inner and outer sides, with coatings applied to both sides to optimize functionality. The outer coating forms an impermeable barrier, while the inner coating features voids that allow fluid to flow into the internal space. The design also includes a textile cover and seal bands that enhance the airtightness of the interface. The patent outlines various configurations and materials used in the coatings and wall portions, emphasizing the balance between breathable and impermeable regions to improve user comfort and prosthetic performance. Overall, the invention aims to provide a more effective and comfortable solution for individuals using prosthetic limbs.
