Abstract: An inflatable mattress comprises superposed lower, middle, and upper sheet layers. The lower and middle sheet layers are joined to each other in a manner to define an inflatable air chamber. The middle and upper sheet layers are secured to each other in a manner to define at least two independently inflatable mattress portions. Fluid passageways provide fluid communication between the air chamber and the inflatable mattress portions. A plurality of ventilation apertures are through the upper sheet layer for ventilating air from the inflatable mattress portions. The sheet layers are arranged such that air introduced into the inflatable air chamber flows through the fluid passageways into the inflatable mattress portions and then out through the ventilation apertures.

Abstract: An orthosis for providing abduction to a patient's legs comprises first and second leg engaging portions configured for operatively engaging first and second legs of the patient and at least one inflatable bladder generally between and operatively attached to the leg engaging portions. The bladder has at least one port for introducing fluid into and removing fluid from the bladder thereby to inflate and deflate the bladder. The bladder is positioned relative to the first and second leg engaging portions so that the bladder resists movement of the leg engaging portions toward each other when the bladder is inflated to maintain the first and second leg engaging portions spaced apart and thereby to maintain the legs of a patient wearing the orthosis spread apart.

Abstract: An ankle/foot orthosis for supporting a patient's ankle in a neutral orientation, including a calf section and a foot section pivotally coupled to the calf section to allow adjustment of a relative angle therebetween. A brace extends between the backsides of the foot and calf sections for maintaining the relative angle in a fixed position, and for allowing adjustment of the orthosis into one of several predetermined positions including an upright position, a fully reclined position, and one or more intermediate positions. The foot section includes a heel portion that maintains positive clearance with a patient's heel, which is an ulcer prominent area, and prevents inadvertent contact therewith, particularly when the orthosis is in the upright position. In the fully reclined position, the orthosis provides access to the patient's heel and sole regions, and elevates the patient's leg and foot above a supporting surface.
