Abstract:
1. A prosthetic device for a lower limb of a user comprising a tibial leg component, having a proximal end forming a socket to be connected to a stump of the user and a distal end, a foot component having a foot shell defining a first cavity within said foot shell and having an open upper part, said foot component being arranged to be articulated to the distal end of the leg component with adapters, and a cover component covering said leg component, wherein said tibial leg component, foot component and cover component are water compatible, wherein the cover component is formed by an hollow flexible sleeve defining a second cavity within said sleeve around the leg component, said cover component being arranged to cooperate contiguously with the socket on one side and with the upper part of the foot shell on the other side by a predetermined overlapping height h, wherein said first cavity communicates with said second cavity, wherein said foot shell comprises a hole on its inner side, said hole overlapping the sleeve by at least one centimeter and presenting an aperture below the sleeve extending to a top surface of an interior of the first cavity of the foot component to provide air communication between the cavities and outside of the device, and wherein the cover component comprises in its upper part, close to the socket, a longitudinal slot comprising two contiguous lips for ventilation, the two contiguous lips arranged to allow water to drain naturally from the first and second cavities when the device has been immerged in and then extracted from water.
