Abstract

Abstract A device for preventing bed sores having a bed pan and a foam pad. The foam pad normally rests upon the top of a bed mattress and has a central portion cut away to matingly receive the bed pan. The bed pan has a bottom wall with vertical walls extending upwardly around the periphery of the bottom wall. Outwardly extending lips are formed around the periphery of the vertical walls and these seat into a recess around the top of the opening so that they lie flush with the top of the foam pad. A plurality of laterally spaced hollow platforms extend upwardly from the bottom wall with the space between the platforms forming drain channels. An air intake nozzle is connected to one of the vertical walls of the bed pan and it in turn is connected to a source of air and oxygen under pressure whose mixture can be controlled. A drain nozzle is also connected to one of the sides of the bed pan adjacent the bottom thereof and it in turn is connected to a vacuum exhaust pump. A perforated cover is removably supported on top of the bed pan.
