  • Patent number: 11737939
    Abstract: Methods and systems of patient offloading include positioning an inflatable transfer mattress in a first position with respect to a surface supporting the inflatable transfer mattress. At least one inflatable positioning wedge is positioned in a second position with respect to the surface. The inflatable transfer mattress is positioned in a third position in which a portion of the inflatable transfer mattress overlaps a portion of the at least one inflatable positioning wedge. The at least one inflatable positioning wedge is inflated to transition the portion of the inflatable transfer mattress overlapping the portion of the at least one inflatable positioning wedge to a non-zero angle with respect to the surface.

  • Patent number: 11439551
    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: 11382806
    Abstract: In one aspect, an inflatable patient handling mattress includes a mattress body, a first lateral extension, a second lateral extension, and one or more lift handles. The mattress body includes a top panel, a bottom panel, and a plenum chamber between the top panel and the bottom panel and configured to be filled with air. The first lateral extension extends from a first side of the mattress body. The second lateral extension extends from a second side of the mattress body, the second side opposite the first side. Each lift handle of the one or more lift handles is attached to one of the first lateral extension and the second lateral extension. The one or more lift handles are configured to be used to lift a patient disposed on the mattress body.

  • Publication number: 20220023121
    Abstract: The present disclosure provides a method of positioning a patient. The patient is provided on a support surface, an inflatable positioning mattress disposed between the patient and the support surface. Air flow into the inflatable positioning mattress is initiated to inflate the inflatable positioning mattress. A downward force is applied on the inflatable positioning mattress proximate to a first side of the support surface. A portion of the inflatable positioning mattress proximate to a second side of the support surface is raised. At least one wedge is positioned beneath the inflatable positioning mattress. Subsequently, the patient is lowered onto the at least one wedge.
