Abstract
A substantially pillow-shaped, inflatable second cushion that is separable and removably interconnected together with the first cushion maintains proper foot flexion when the body is in the supine position, and is removable to allow ambulation while the foot and lower leg remain cradled in the first cushion. A substantially pillow-shaped, inflatable third cushion is pivotally attached to the bottommost compartments of the first cushion and is pivotally positionable either directly under the Achilles' heel area, or directly under the heel area, or tucked forward of the heel area to provide light compression of the ankle, foot and heel areas. An integral shoe spoon attached to the first cushion prevents the foot cushion from catching bed clothing. A rigid base is provided for rigidly fixing the first inflatable cushion in position to prevent contraction of the feet of comatose patients, for example. A novel connector with two-finger pinch-to-open releasing action provides easily adjustable straps to secure the first cushion non-circumferentially about a foot and lower leg.
