Abstract
A multi-modal patient support system is provided having the capability of switching from any one of at least three modes of operation, particularly a first constant pressure mode, a second pulsation, and a third turning mode. A plurality of like inflatable sacs are provided supported upon a rigid support member. The inflatable sacs comprise at least two internal chambers. In the first static mode, the inflatable sacs are maintained at a relatively constant predetermined pressure. In the second pulsation mode, at least two sets of inflatable sacs are inflated and deflated in at least two separate and opposite patterns of pressurization so as to provide alternating pressure point relief to a patient resting upon the sacs. In the third turning mode, generally opposite disposed portions of the inflatable sacs are alternately inflated and deflated so that a patient resting upon the sacs can be automatically tilted from side to side. An inflatable sac for use with the multi-modal patient support system is further provided.
