Abstract
The invention relates to an orthopaedic aid, in particular to a prosthesis () or orthosis comprising an orthopaedic fluid damper () with a displacement chamber () formed in a housing (), with a piston () mounted in the displacement chamber (), with a fluid reservoir for a fluid (), with a return flow conduit () connecting the displacement chamber () to the fluid reservoir, with a valve () that can adopt an open position and a closed position, in which it at least partially closes the return flow conduit (), and with a joint () that has a first branch () and a second branch (), wherein the first branch () is connected to the housing () and the second branch () is connected to the piston (). A device () is also provided for detecting a joint force (FB) acting on the joint, which device () is designed to bring the valve () to the closed position when the joint force (FB) exceeds a predefined threshold value. The invention also relates to a method for control of the aid and a fluid damper () fitted therein.
