Air control system for enhancing a connection between a limb liner and a limb prosthesis

A system for joining a prosthesis to a residual limb of an amputee, said system comprising:

• a limb liner to be worn over the residual limb, wherein said limb liner has a locking pin extending therefrom;
• a prosthesis having a socket sized to receive said limb liner, wherein said socket has an open top, a bottom opposite said open top, and an interior that extends from said open top to said bottom;
• a first hub disposed within said interior of said socket;
• a second hub disposed outside said interior of said socket, wherein said second hub mechanically connects with said first hub to form a hub assembly, wherein said hub assembly defines an air conduit that leads through said second hub and said first hub, therein enabling air to flow into said interior of said socket from outside said socket;
• a receptacle for receiving said locking pin that is separate, distinct and offset from said air conduit, wherein said receptacle extends through said first hub and into said second hub, and
• an inflatable interface disposed between said socket and said limb liner, wherein said inflatable interface is selectively inflated through said air conduit.

A prosthesis to be worn on a limb with a limb liner, said prosthesis comprising:

• a prosthetic foot;
• a shaft extending from said prosthetic foot, wherein said shaft terminates away from said prosthetic foot at a second hub;
• a socket having an open top, a bottom, and an interior that is accessible through said open top;
• and
• a first hub disposed within said interior of said socket;
• wherein said first hub and said second hub are joined together with mechanical fasteners through said bottom of said socket to form a hub assembly;
• wherein said first hub has a first port and said second hub has a second port, wherein said hub assembly defines an air conduit that extends through said hub assembly from said first port to said second port when said first hub and said second hub are joined;
• and
• a pin receptacle extending through said first hub and into said second hub, wherein said pin receptacle is accessible within said interior of said socket, and wherein said receptacle is separate and distinct from said air conduit.
