A mobile assembly of devices designed to enable one person to lift and move an incapacitated patient or a person with a disability, of any size and weight, safely and with minimal physical effort. Also known as a patient hoist, it typically consists of a support base on wheels with a lifting mechanism, mast, boom, swivel bar, and patient holding device (e.g., a sling, holder or a frame). The lifting mechanism is power-assisted (e.g., using pneumatic springs) to aid manual movement of components. It is typically used to lift and move the occupant in a sitting or semi-sitting position over short distances within the treatment facility, e.g., from a bed to a bathroom.
