A novel method of lifting a patient from a seated to a generally standing position employs a hoist comprising a support column mounted on a mobile chassis. A pivotal lifting arm arrangement projects from the column and presents laterally spaced attachment points for a padded sling which is passed around the back of the seated patient below the arms thereof. The hoist is positioned with knee abutment means, which are mounted on the column, located against the knees of the patient; and the feet of the patient are placed on footrests mounted on the chassis on opposite sides of the column. A lifting mechanism comprises a pivotal operating lever connected to the arm arrangement through a mechanical linkage which provides a mechanical advantage, such that operative movement of the lever through 180 DEG from an upwardly projecting to a downwardly projecting position pivots the arm arrangement upwardly through an angle of say 60 DEG to 65 DEG thereby raising the seated patient to a standing position on the footrests while suppported at the back and laterally located by the sling. |
