ABSTRACT:
An inflatable mattress having multiple compartments which may be selectively inflated and deflated to produce variable contact of the mattress with the occupant's body. Some of the compartments may be active, and others inactive, with the active compartments of the mattress controlled by automatic controls to cyclically inflate and deflate the compartments. The device may be operated manually to allow the operator to deflate the necessary compartments for placement of a bedpan, or other access to the occupant. Multiple foam rubber wedges are inserted into deflated compartments, then inflated to turn the occupant on his or her side. Various embodiments are inflated by air, nitrogen or water. A water-to-air heat pump, or an air-to-air heat pump may be used to control the temperature.
