Continuous wave cushioned support |
摘要 |
Multiple foam-filled cells form a cushioned support surface of a seat or mattress. Individual cells may be collapsed by connection through a manifold and valve to a vacuum source. The collapsed cell essentially removes contact pressure in a localized area of the person supported on the surface and restores localized blood flow. After a pre-determined time interval, atmospheric pressure is readmitted to the cell.
