IMPROVED FLUIDIZED SUPPORTING APPARATUS

摘要

A fluidized patient support structure in which a mass of granular material is received within an open top container between a fluid diffuser plate and a flexible sheet on which the patient may lie in a supine position. Pressurized fluid passes through the diffuser plate and suspends the granular material in a fluidized form. The diffuser plate has a predetermined variable contour and a predetermined depth of fluidized material thereabove adequate to support a patient in a supine position.
