Abstract: The mattress includes a main assembly, a pair of bolsters, and a bottom assembly. The main assembly is adapted to overlay the conventional mattress of the bed, and has opposing longitudinal sides, and comprises a plurality of cells that are selectively inflatable for moving the patient in the preselected ways so as to prevent the patient from having the skin breakdowns. The pair of bolsters are replaceably attached to, and extend along, the opposing longitudinal sides of the main assembly, and are inflatable, and when inflated, form barriers that prevent the patient from falling off the bed when the patient is turning. The bottom assembly is adapted to overlay the conventional mattress of the bed and underlie the main assembly, and when inflated, forms a static air space between the main assembly and the conventional mattress of the bed that prevents the patient from bottoming out on the low side of the turning, while suspending the patient in the cushion of static air if the power to the main assembly fails.

Abstract: An anti-decubitus pneumatic mattress adapted to replaceably overlay a conventional mattress of a bed and have a patient move in preselected ways so as to prevent the patient from having skin breakdowns, and from falling off the bed when the patient is turning, and from bottoming out on a low side of the turning, while being suspended in a cushion of static air, if power to the anti-decubitus pneumatic mattress fails. The mattress includes a main assembly, a pair of bolsters, and a bottom assembly. The main assembly is adapted to overlay the conventional mattress of the bed, and has opposing longitudinal sides, and comprises a plurality of cells that are selectively inflatable for moving the patient in the preselected ways so as to prevent the patient from having the skin breakdowns.

Abstract: A plurality of pairs of inflatable air cells disposed on opposite sides of a longitudinal axis are arranged along the length of a bed. Each of the air cells extends substantially transverse to the longitudinal axis and are supplied with air so that cells on alternate sides are inflated while simultaneously the cells on the other side are deflated. An upper layer of a resinous foam pad is provided on which the patient lies. The pad is provided with a groove along its longitudinal axis for comfort of the patient. The assembly is completed by a covering having an upper sheet member removably attached to a lower sheet member so that when soiled it may be easily removed.
