Abstract
A spinal therapy machine having an inflatable bladder. A rigid restraint running around the bladder causes the inflation to rise rather than to expand outward. Rings connected to the ends of the bladder are slidably attached to one or more posts that extend generally perpendicular to whatever structure upon which the bladder is placed. Either a control unit operated directly by the user or a computer direct the inflation of the bladder and, consequently, the elevation of a pad removably attached to the top of the bladder. Inflation is provided by a vacuum motor preferably connect to the bladder with a large tube in order to enable rapid changes in the degree of inflation.
