Abstract
The system of present invention is intended for use with a bed having a drive system for moving at least one movable section of the bed and a weight meter which receives transducer signals from transducers in the legs of the bed and displays a patient weight. In the system of the present invention the weight meter is operably coupled to the drive system so that when the drive system is activated, the weight meter automatically enters a hold mode wherein the weight meter stores the most recent weight value as a hold weight value. When the bed drive system is deactivated, the weight meter automatically returns to the operating mode by converting changes in the signals from the transducers into a change in weight value that is added to or subtracted from the hold weight value.
