| 摘要 |
A therapeutic mattress for bed ridden patients comprises a plurality of inflatable tubular elements fabricated from a low air loss material which are disposed in side by side, transverse relationship to a mattress supporting surface. The air pressure within the various tubular elements is cyclically varied to produce a wave-like deformation of the patient supporting surfaces of the tubular elements which progresses longitudinally along a selected portion of the length of the mattress.
