Title of Invention

INFLATABLE SUPPORT

Abstract A support surface 10 includes a series of inflatable cells 30, 40 inflated alternately by a compressor 11. The cells 30, 40 are exhausted via an exhaust port 50 having a restrictor 60 of known diameter. A pressure transducer 70 measures the cell 30, 40 pressure. Some of the cells 30, 40 during their deflating/inflating cycle are exhausted through the exhaust port 50 and the cell pressure decay over a time is monitored. A microprocessor calculates the mathematical function related to the cell pressure decay with time, compares the value with compiled data and adjusts the output of the compressor accordingly. The sequence of exhausting via port 50 is repeated at every inflation/deflation cycle and the pressure decay monitored and compared with the known data and the compressor output adjusted automatically to provide a new operating pressure. Therefore, any changes in the person's position i.e. supine, to side or sitting are accomodated by the cell pressure automatically being adjusted to prevent bottoming or high interface pressures.
