  • Portable lifting systems and methods for assistance in standing
    Publication number: 20060150321
    Abstract: A portable, lightweight device is provided that permits a person to be lifted from a sitting position without the assistance of another person. This device comprises an inflatable bladder and a means of forcing a gas into the bladder. When the person wishes to be lifted from a sitting position, the person merely inflates the bladder, which is positioned appropriately. The inflating bladder then lifts the person to a standing or partially standing position in a safe and controlled manner.
