Two components of the disclosed invention are critical. Utilizing a plurality of flexible and hollow cells capable of being repeatedly filled and depleted with a fluid, preferable air, the cells being arranged so that (1) the cells being depleted are next to or contiguous only with cells that are not being depleted, those cells being depleted of fluid must not be in contact with the individual such that a pocket of air exists between the depleted cell(s) and the individual, and (2) the temperature of the cells is maintained at or about an average of about 5 degrees Fahrenheit less than the average body temperature of a healthy human, but not less than about 25 degrees Celsius. The phrase “pocket of air” as used herein is intended to convey a gap or space between deflated cell(s) and the skin (even in circumstances where a sheet or other cover is between the cushion and the skin) such that skin surrounding the pocket or air is supported by non-depleted cells, and the skin directly above or on the region of depleted cells is not in contacted with the depleted cells. In this manner, those portions of the skin above the pocket of air created by the fully depleted cell(s) are, in essence, not in contact with the cushion to allow complete disassociation between those portions of the skin and the depleted cell(s). The term “average” in reference temperature of the cells is intended to convey that the temperature can be regulated so as not to be uncomfortable for the individual using the cushion, and need not be maintained at a constant temperature. | 04-14-2011 |
