Abstract
A vacuum pump may be used to attach a prosthetic and/or orthotic device to a residual limb. The vacuum pump may be in line below a socket of a residual limb. The socket may be a portion of the prosthesis that accepts the residual limb. The vacuum pump may generate a vacuum condition between the prosthesis and the residual limb. Generally, a vacuum condition may be generated between a socket and the residual limb. The residual limb may be covered with a sock, elastomeric liner, or sheath covering the limb. The vacuum condition may positively attach the prosthesis to the residual limb without the need for straps, retaining pins, or suction type vacuum which do not use a vacuum pump.
