Patent number: 7565709Abstract: A double chambered transfer mattress is provided capable of partial deflation that that includes a top inflatable mattress and a bottom inflatable mattress that are separated by a common wall from one another. A selectable inlet/outlet valve is arranged for airflow communication between an interior chamber of the bottom inflatable mattress and a source of pressurized air. A one-way valve is positioned through the common wall so as to provide selective air flow communication between the top inflatable mattress and the bottom inflatable mattress so that when the inlet/outlet valve is closed, so that air continues to escape from perforations in the bottom inflatable mattress, the one-way valve is actuated so as to prevent deflation of the top inflatable mattress.Type: GrantFiled: April 15, 2008Date of Patent: July 28, 2009Assignee: Woodlark Circle, Inc.Inventor: David T.

Publication number: 20080289102Abstract: 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.Type: ApplicationFiled: May 22, 2007Publication date: November 27, 2008Applicant: WOODLARK CIRCLE, INC.Inventor: David T.

Patent number: 7373680Abstract: 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.Type: GrantFiled: November 29, 2004Date of Patent: May 20, 2008Assignee: Woodlark Circle, Inc.Inventor: David T.
