Abstract: A normally-deflated, readily-flexible, inflatable pad which underlies a bed patient can be inflated to raise that bed patient and to gently but firmly hold that bed patient in raised position. When that inflatable pad is inflated, it defines a recess at the lower surface of the center thereof into which the supporting surface of a portable support can be moved; and that inflatable pad and that portable support can thereafter hold the bed patient at a desired level relative to the bed on which that inflatable bed normally rests. When the supporting surface of the portable support subsequently is removed from the recess at the lower surface of the center of the inflatable bed, that inflatable pad can be deflated to lower the bed patient. A pressure transducer, between the supporting surface and the carrier therefor, develops a signal while that supporting surface underlies and holds the inflatable pad and the bed patient; and a readout responds to that signal to indicate the weight of that bed patient.
