Pump system

A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.

Hydraulic damper with valve block

A hydraulic actuator includes a housing and with a chamber, which is arranged or formed in the housing and in which a piston is mounted movably and divides the chamber into a flexion chamber and an extension chamber. A channel for hydraulic fluid leads from the flexion chamber and the extension chamber into the housing in order to produce a fluidic connection between the flexion chamber and the extension chamber. At least one valve is arranged in the fluidic connection. The channels lead from the housing to a valve block in which the at least one valve is arranged and is fluidically coupled to the channels, and the valve block is connected to the housing.

Prosthesis for femoral amputee
11273059 · 2022-03-15 · ·

A hinged connecting device comprising a damping mechanism intended to counter a predetermined resistance at least during bending of the prosthesis (1), by replacing the muscle groups usually used for this purpose. The damping mechanism (200) is capable of being switched between a first operating mode (M1), selected by default, in which the value of the resistance corresponds to a first maximum value (Vmax), and a second operating mode (M2), that can be actuated only in a hyperextension position (P0) of the prosthesis (1), in which the resistance value corresponds to a second minimum value (Vmin); and the hinged connecting device (2) moreover comprises a fully mechanical locking system (3), arranged in order to allow the second operating mode (M2) to be activated only when the inclination of the tibial part (102) exceeds a first predetermined oriented angle (X1) relative to the vertical.
