Abstract: The novel portable knee and elbow joint apparatus is comprised of a unit that is designed to allow the individual using the apparatus a self determined amount of support pressure by the apparatus in those joints. The apparatus has a bladder chamber that channels air in the bladder in such a manner that optimizes the support shape around the elbow and knee joints. A plastic spring check valve attached to a flexible bulb directs the air into the bladder and maintains the air therein. The apparatus is composed of flexible material that wraps around the joint and positions the open bladder around joint. A fiber mesh covers the top of the bladder. Reinforcement stays are positioned vertically at each side of the brace apparatus in order to maintain the shape of the apparatus.
