Abstract: A transfer mattress includes an upper mattress having three longitudinally oriented plenums and three separate inlet/outlet valves that are each arranged in airflow communication with their respective plenum. First and second of the plenums are arranged in airflow communication with one another while a central plenum is arranged in airflow isolation from the first plenum and the second plenum so that the first and second plenums may be inflated and deflated independently of the central plenum. A lower inflatable mattress is separated by a common wall from the upper mattress. A lower inlet/outlet valve is arranged in airflow communication with a lower plenum defined by the lower inflatable mattress. A bottom wall defines a plurality of perforations so that when the lower plenum is charged with pressurized air, it escapes under pressure through the perforations to create an air bearing under the mattress. A method for transporting a patient in comfort is also provided by the invention.

Abstract: An inflatable lifting cushion for an articulated chair including a five-sided polygon capable that is longitudinally aligned on the seat and back of the chair. The cushion includes triangular side walls and at least one interior plenum having an air inlet port enabling air to enter and exit the plenum. A system for transferring a patient is provided including an articulated chair having a back and seat that are arranged to cooperate with one another for movement between an upright position and a reclining position. An inflatable lifting cushion is longitudinally positioned upon the back and the seat of the articulated chair. The inflatable lifting cushion comprises a five-sided polygon including triangular side walls and at least one interior plenum having an air inlet port enabling air to enter and exit the plenum. Another a system for transferring a patient is provided that includes an articulated chair having a back and seat that are arranged to cooperate with one another for movement between an upright position and a reclining position. An inflatable lifting cushion is longitudinally positioned upon the back and the seat of the articulated chair. The inflatable lifting cushion comprises a five-sided polygon including triangular side walls and at least one interior plenum having an air inlet port enabling air to enter and exit the plenum. A transfer mattress is positioned upon the lifting cushion for movement of a patient onto an adjacent bed.

Abstract: A convertible wheeled chair is easily changed by an attendant into a gurney of the same height as a patient bed. During the process of transferring a patient from an upright position to a reclining position, convertible wheeled chair shifts the center of gravity of the patient rearwardly, and therefore does not give the patient a sensation of sliding from the chair.

Abstract: A transfer mattress is provided including a top sheet having a width, a length, and longitudinally oriented peripheral edges and a bottom sheet having the same width, the same length, longitudinally oriented peripheral edges and a plurality of perforations. The longitudinally oriented peripheral edges of the top and bottom sheets are sealingly fastened to one another often by heat sealing. A plurality of baffles, each having a width and a length, are attached to an inner surface of the top sheet and an inner surface of the bottom sheet so as to be transversely oriented between the top sheet and the bottom. The baffles along with the widths of the top and bottom sheets define a radially-outwardly curved perimeter wall that is disposed between an edge of the baffles and the sealed peripheral edges of the top and bottom sheets. The radially-outwardly curved perimeter wall has a width y that is determined by the following relationship: d ⁢   ⁢ π - x 2 ≤ y where d comprises a height of the longitudinally extensive pontoon and x comprises the width of the baffles.
