| 20110295386 | VALVE SYSTEM FOR PROSTHETICS - A valve system regulates the air pressure in the space(s) between a residual limb, or liner-covered limb, and a hard socket of an external prosthesis, for example, for improving donning and doffing the prosthesis, and/or during walking and other normal use of the prosthesis. The valve system may include a manually-controlled air outlet and inlet valve that may be installed on a distal region of a hard socket, and/or an automatic one-way outlet valve. The manually-controlled valve is preferably opened and closed by twisting of a handle portion of the valve system, wherein partial rotation of the handle portion relative to the base portion of the valve system creates slight separation of the handle and base portions to form a gap through which may pass air from the well of the socket. This simple twisting, or partial rotation, provides a valve that stays open hands-free, so that the wearer may open the valve and then use his/her hands to don or doff the prosthesis. The manual valve may include a system for preventing the handle and base from becoming entirely separated during normal use, which preferably is a snap-fit of the base onto the handle that retains the ability of the handle and base to rotate relative to each other, and a stop(s) that limit(s) the amount of relative rotation of the handle and base portions of the valve. Opening and closing of the manual valve may be accomplished by a ramp system, so that, upon rotation of the handle in one direction, the handle comes close to, and seals with, the base, and upon rotation of the handle in the opposite direction, the handle becomes slightly distanced from, and unsealed from, the base. | 12-01-2011 |
