<p>A mobile hospital patient bed scale is contemplated which lifts the entire bed with patient in situ on a load platform (9) with a non-slip surface. The scale minimizes both vertical and horizontal displacement. The platform (9) has load cells (8) which deliver data to a memory and display device. The invention is portable and partly foldable to aid in storage. It provides for recharging if desired, and for use of an auxiliary power source if desired. The driving force (5) for lifting may be a hydraulic ram or an electrically powered screw drive.</p> |
