Leg Lift/Mover

Instead of forcing wheelchair dependence onto immobile patients, we would like to provide devices that support the notion of walking again. This concept would be a wearable device to lift and maneuver one or both legs. The device would allow, for example, a stroke victim or leg-injured patient to independently and frequently exercise the affected leg toward rehabilitation, leg exercise, gravity compensation for the leg, or in some case learning to walk again. This tendon-driven device would be minimally invasive and could be configured as a pair of trousers with the tendons along the fabric. Motors can be worn on the belt and a special shoe with tendon connections would provide the necessary lift points. A modified, off-the-shelf knee support would provide the interim cable routing. And, the patient's leg bones would provide the compression members. The concept is now being studied at NIST.

Patient Lifter

Based on the RoboChair concept and as a first step to inserting a human-lift device into the healthcare industry, the LIFTER is designed to allow a persons' upper body to be lifted and the person placed on a bed, chair, toilet or even floor. Mobility is self/caregiver-powered (walking), assist-power (optional - walk with some mobility power from LIFTER), or powered (optional - full mobility power from LIFTER). Powered requires additional drive motors not shown in the graphics. Also, for typical stroke victims where the right leg is not or partially functional, a fold down, removable footrest can be optionally attached to the right side. For full mobility, footrests for both feet can fold down.
