FEMORAL PROSTHESIS USABLE IN WATER ENVIRONMENT AND METHOD FOR MANUFACTURING SUCH PROSTHESIS

摘要

A prosthetic device for a lower limb of a user is provided which includes a femoral leg component, a foot component and a cover component which are water compatible. The cover component includes one or more hollow sleeves defining one or more cavities in communication with a cavity provided in the foot component. The foot compartment includes a hole overlapping the one or more hollow sleeves which is configured to evacuate water from the prosthetic device and to provide air communication between the one or more cavities and the exterior of the prosthetic device. The cover includes a flexible venting opening so that the water drains naturally from the one or more cavities. A method of manufacturing the prosthetic device is also provided. The method includes manufacturing a cover with successive layers forming the cavities, with the cavities configured such that water drains naturally from the prosthetic device.

1. A prosthetic device for lower limb of a user comprising a femoral leg component, having a femoral part presenting a proximal end forming a socket to be connected to the stump of the user, an intermediate knee part and a tibial part having 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 tibial part with adapters, and a cover component covering said leg component, said leg, foot and cover components being water compatible,
wherein the cover component is formed by a femoral cover part, a knee cover part and a tibial cover part, said femoral cover part being formed by a hollow flexible first sleeve arranged to cooperate contiguously or overlappingly with the socket on one side and with the knee cover part on the other side, said knee cover part being formed by a second sleeve defining a second cavity within said second sleeve around said knee component, said second sleeve being formed by a flexible self-carrying hollow tubular portion comprising a semi-rigid top end connected to said femoral cover part, an intermediate portion having a semi-rigid front end, and a flexible back end arranged to authorize the flexion of the knee component, and a semi-rigid bottom end connected to said tibial cover part, and said tibial cover part formed by a hollow flexible self-carrying third sleeve defining a third cavity within said third sleeve around the tibial part and in communication with said second cavity, said tibial cover part being arranged to cooperate contiguously or overlappingly with the bottom part of the knee cover part on one side and to cooperate overlappingly with the upper part of the foot shell on the other side on a predetermined height, said first cavity being in communication with said third cavity, said foot shell comprising a hole on its inner side, said hole overlapping the third sleeve for evacuation of the water and presenting an aperture below the third sleeve to provide air communication between the cavities and the exterior of the device, and wherein the cover component is arranged to provide in an upper part a flexible venting opening for ventilation, so that the water drains naturally from the first and second cavities.
