Abstract
A system for determining a location of a patient on a hospital bed comprising: at least one deformation sensor adapted to generate a signal indicative of a deformation of a frame of the bed; a location determination unit for determining a lateral and/or longitudinal location of the patient based on the deformation of the frame. A method for monitoring an exit of a patient from a hospital bed comprising: determining a patient location on the bed based on measured deformation and generating an alarm signal if the determined location is outside a predetermined area. A weight sensing system for a hospital bed having a base with a suspended frame suspended from a fixed frame comprising: a load sensor connecting the suspended frame and the fixed frame via a suspension member which is unsecured from the fixed frame to allow free vertical movement of the suspended frame relative to the fixed frame.
