Abstract:
A variable geometry attachment fitting system for use in conjunction with a body appliance to be removably attached to a body part, comprising:a reservoir of non-leaking material, said reservoir having reservoir filling means for adding fluid to or removing fluid from said reservoir; at least one pressure bladder made of a substantially pliable fluid-tight material capable of conforming to at least a portion of the appropriate soft tissue areas of the body part, said at least one pressure bladder having a fluid inlet, wherein said at least one pressure bladder is disposed between the body part and the body appliance; at least one pumping bladder made of a substantially pliable fluid-tight material, said at least one pumping bladder operates as an automatic fluid pump communicating between said reservoir and said at least one pressure bladder for delivering pressurized fluid stored in said reservoir to said at least one pressure bladder, such that the pressure within said at least one pressure bladder may be increased with movement; a fluid circuit operably interconnected between said reservoir, said at least one pumping bladder, and said at least one pressure bladder, said fluid circuit including pressure control means for regulating and maintaining a predetermined pressure in said at least one pressure bladder; and said pressure control means comprises means for providing controlled leakage of the fluid from within said at least one pressure bladder, such that the pressure within said at least one pressure bladder may be decreased.
