  • Publication number: 20200146913
    Abstract: An inflatable transfer mattress includes a top panel, a bottom panel having a perimeter sealingly coupled to a perimeter of the top panel to define an internal volume therebetween, and a rotational positioning device coupled to the top panel. The internal volume is configured to receive an air flow therein. The rotational positioning device is positioned outside of the internal volume and includes at least one inflatable bladder configured to be inflated from a deflated state to an inflated state. The bladder portion is configured to rotate a patient to a predetermined angle with respect to the top panel in the inflated state.

  • Patent number: 8387177
    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.

  • Publication number: 20110056502
    Abstract: An intubation pillow formed by a base cushion that forms a torso-support portion and defines a recess sized and shaped so as to provide proper alignment of the oral, pharyngeal, and laryngeal structures forming a person's airway. A head-support cushion that is positionable within the recess is provided so as to provide proper alignment of the oral, pharyngeal, and laryngeal structures that form a person's airway such that unlabored normal breathing may be maintained both prior to and after an intubation procedure.

  • Patent number: 7712170
    Abstract: A single patient, personal use patient transfer mattress is provided including at least a substantially permanently stainable 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. 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.
