Prosthetic device, system and method for increasing vacuum attachment |
| abstract |
A prosthetic system includes a prosthetic foot defining an upper surface and having a flexible configuration and a pump system attached to the prosthetic foot. The pump system includes a pump mechanism defining a fluid chamber having variable configuration and an actuating part. The actuating part is arranged to selectively engage with and separate a distance from the upper surface of the foot plate to move the pump mechanism between a first position in which a volume of the fluid chamber is zero or near-zero and a second position in which the volume of the fluid chamber is expanded relative to the first position. The volume of the fluid chamber increases when the actuating part moves away from the upper surface of the foot plate. |
