Abstract:
A mobile bed scale comprising:a mobile base frame moved on a floor; a horizontal bed support to be slid under a hospital bed sufficiently large to stably support such bed when such horizontal bed support is raised; lifting apparatus for elevating said horizontal bed support with no horizontal displacement of a hospital bed being lifted; said lifting apparatus for elevating said horizontal bed support being mounted on said mobile base and being mounted generally beneath and adjacent to said horizontal bed support; said lifting apparatus being a mechanical scissors lift; said horizontal bed support, said lifting apparatus, and said mobile base frame being sufficiently low above said planar surface on which said mobile base frame is moved to be slid under a hospital bed; a fluid-driven power source for causing said lifting apparatus to elevate said horizontal bed support; said power source being mounted on said mobile bed scale; said power source being further operable by a human without auxiliary power; said power source for causing said lifting apparatus to elevate said horizontal bed support, and said horizontal bed support, being adjustably operable to a raised position by a human from a standing position; said horizontal bed support having a weight sensing means; said weight sensing means being at least three piezoelectric sensors; said weight sensing means being connected by a wire harness to a display; said display means being mounted on said mobile base frame on an arm extending generally upwards from said mobile base frame to permit visual perception of said display means by a human in a standing position; and at least one pop-down floor grip to prevent said mobile bed scale from moving during patient weighing, which grip is actuable and releaseable by foot action.
