Patent number: 8113235Abstract: Apparatus and methods for improved prosthesis donning, doffing, retention, and fit. A valve located in a prosthetic socket port includes a body, a core, a spring located partially within the core, a diaphragm, and a maintained operator. The operator includes a recess and a protrusion. The operator may be indexed to a displacement or vent position. When the operator is indexed to the displacement position, a tip of the core is pressed against the recess via the spring, and the diaphragm displaces any air that enters into the prosthetic socket when a load is applied to the residual limb. When the operator is laterally actuated, it is indexed to the vent position and the core tip moves from the recess to the protrusion. In this position, the diaphragm opens the socket cavity to the external atmosphere via valve vents, thereby facilitating prosthesis donning and doffing.Type: GrantFiled: October 3, 2008Date of Patent: February 14, 2012Inventor: David Robert Bogue
