Abstract
A patient turning device for a patient support apparatus. The patient turning device includes a first and second bladder assembly each including a plurality of layers and seals defining a bladder volume. The bladder volumes are selectively inflatable with fluid to expand the respective bladder assembly, and consequently move a patient support surface of the patient support apparatus. A portion of a lower layer of the first bladder assembly and a portion of an upper layer of the second bladder assembly define an overlapping region of the bladder volumes. The patient turning device is coupled to an underside of a carrier sheet and positioned between a crib assembly and a bottom cover. An augmenting feature is configured to resiliently expand as at least one of the first and second bladder assemblies receives the fluid to move at least a portion of the crib assembly away from a patient support deck.
