  • Patent number: 11931305
    Abstract: A portable, lightweight emergency lifting device for downed persons that is intended for use by paramedics/emergency personnel as well as medical facilities and private owners. The lifting device has a redundant, fail safe lifting system utilizing twin electric screw jacks. It has a seat with a ramped front edge that extends to the ground when the device is in its collapsed configuration to aid in loading the patient. The vertical legs open only to an acute angled position so as to leave the immediate area under the seat open and uncluttered. The frame is on casters and the seat resides between the horizontal frame members when the device is in its collapsed configuration thus allowing the lowest possible pick up of a patient.
