20100180384 | MATTRESS - Air mattresses primarily intended for hospitals, long-term care facilities and in-home use are described. The mattress includes multiple foam layers and an air sector having multiple resilient foam filled air cylinders. The air cylinders at different locations are filled with foam having different density (firmness); some are filled with multiple layers of foam. Each air cylinder has an air inlet connected to the atmosphere by an inlet valve and an air outlet. The air outlets are either connected to one or more restricted internal check outlet valves in a non-powered air mattress, or connected to a pump via hose connectors in a powered air mattress. The restricted outflow of air from the cylinders in a non-powered air mattress allows the patient to slowly settle into the supportive foam layers for optimal interface pressure distribution. The air cylinders re-inflate when the patient adjusts position or is vacated from the surface. | 07-22-2010 |
20100281618 | INTERNAL STRUCTURAL CONFIGURATIONS OF BLADDERS USED IN PATIENT SUPPORT SYSTEMS - A bladder comprising an outer and inner surface having a length, height and width, first and second ends, and an internal volume. A support structure is disposed within the bladder and has a length, width, height as well as an inner and outer region. The outer region of the support structure comprises support projections which define openings in the outer region of the support structure. The support projections have an engaging end which contacts the inner surface of the bladder and exerts force upon the inner surface of the bladder. The support projections maintain the internal volume of the bladder in a no-load sate. The openings in the support structure allow air to move freely in the bladder versus a solid support structure lacking openings. This aids in distribution of air within the bladder and provides air-like pressure management and comfort in addition to the structural support provided by foam inserts. | 11-11-2010 |
