ABSTRACT:
A portable orthopedic bed for the correct orthopedic support of a patient has a longitudinally adjacent array of laterally extending air inflatable chambers wherein the array has a first set of chambers and a second set of chambers. A set of chambers has a lower back supporting chamber adjacent a midpoint between the first and second sets of chambers, the lower back chamber also adjacent an upper back supporting chamber on an opposed side of the lower back supporting chamber from the midpoint, an upper foundation chamber adjacent the upper back supporting chamber on an opposed side of the upper back supporting chamber opposed to the lower back supporting chamber, wherein the upper foundation chamber is generally triangular in longitudinal cross section to thereby provide a buttressing foundation for the upper back supporting chamber. A lumbar supporting chamber has an independently inflatable chamber from the lower back supporting chamber and disposed generally adjacent the lower back supporting chamber beneath the lumbar area of a patient lying on the portable orthopedic bed with a coccyx of the patient located generally at the midpoint. A set of chambers has a thigh supporting chamber adjacent the midpoint and extending between the midpoint and an adjacent lower foundation chamber on an opposing side of the thigh supporting chamber to the midpoint and a lower leg elevating chamber overlaying the lower foundation chamber.
