Moving pressure support

Abstract

The support product repeatedly moves points of maximal pressure between the product and a weight supported by the product, which is especially useful for avoiding problems such as bed sores.

1 . A support product which repeatedly moves pressure between the product and a weight supported by the product, the product comprising: 
 a chamber;    beads,    the beads being in the chamber,    the beads providing a changeable configuration of points of maximal pressure between the chamber and an object supported on the chamber; and    moving means for moving the beads in the chamber to cause the changeable configuration of points of maximal pressure to change repeatedly while the object is supported,    the moving means being in the chamber with the beads.    
     
     
         2 . The product of  claim 1  wherein there is a lubricating fluid in the chamber for easing moving the beads.  
     
     
         3 . A support product which repeatedly moves pressure between the product and a weight supported by the product, the product comprising: 
 a chamber;    beads,    the beads being in the chamber,    the beads providing a changeable configuration of points of maximal pressure between the chamber and an object supported on the chamber; and    moving means for moving the beads in the chamber to cause the changeable configuration of points of maximal pressure to change repeatedly while the object is supported,    the moving means being in a second chamber.    
     
     
         4 . A support product which repeatedly moves pressure between the product and a weight supported by the product, the product comprising: 
 a chamber;    beads,    the beads being in the chamber,    the beads providing a changeable configuration of points of maximal pressure between the chamber and an object supported on the chamber;    moving means for moving the beads in the chamber to cause the changeable configuration of points of maximal pressure to change repeatedly while the object is supported,    the moving means being in the chamber with the beads; and    a lubricating fluid in the chamber for easing moving the beads.    
     
     
         5 . A support product which repeatedly moves pressure between the product and a weight supported by the product, the product comprising: 
 a chamber;    beads,    the beads being in the chamber,    the beads providing a changeable configuration of points of maximal pressure between the chamber and an object supported on the chamber;    moving means for moving the beads in the chamber to cause the changeable configuration of points of maximal pressure to change repeatedly while the object is supported,    the moving means being in a second chamber; and    a lubricating fluid in the chamber for easing moving the beads.
