ABSTRACT:
A hospital bed includes a support frame which is supported on the bed by four load cells and which in turn supports a mattress having a patient thereon. A method and apparatus of detecting patient exit from the bed involve extraction from the weight measured by each load cell of the portion of the measured weight corresponding to the weight of the patient, use of this extracted weight information to calculate a center of gravity of the patient with respect to the frame, a determination of whether the calculated center of gravity is within a predetermined region, and generation of an alarm if the center of gravity is outside the region.
