Abstract
A prosthesis system includes a reconfigurable socket. The socket changes configurations to adjust the socket fit. The socket includes a socket main body with a window and a panel positioned in the window. The panel and the socket main body cooperate to define a cavity for receiving a residual limb. A lacing system is coupled to both the socket main body and the panel and moves the panel with respect to the socket main body to adjust a volume of the cavity. A tensioning mechanism holds the lacing system to position the adjustment panel. The prosthesis system also allows for the escape of moisture from within the cavity.
Claims6
A prosthesis, comprising:
- a liner system for placement in a socket, the liner system including:
- a water vapor permeable, air-impermeable air barrier layer having an air barrier layer front side and an air barrier layer back side, the air barrier layer front side defining an interior cavity for receiving a residual limb;
- a ventilation layer on the air barrier layer back side, the ventilation layer including a plurality of venting features through which moisture passes to manage the moisture at an interface between a user's skin and the liner system, the venting features comprising channels in the ventilation layer;
- and
- at least one reinforcement structure positioned along one of the channels in the ventilation layer and configured to keep the channels in the ventilation layer open, wherein the at least one reinforcement structure includes a plurality of tubular members positioned within lumens of the channels in the ventilation layer.
