摘要： 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.

摘要： A pressure pad (1) has two sets of cells (11, 12) with a sensor pad (8) positioned under the pad (1). During inflation, part of the flow goes to the sensor pad (8) to exhaust and the rest fills the cells (11 or 12). Any change in patient position/weight causing a change in airflow in tube (10) will alter the differential pressure measured at the pressure transducer (16). Based on this feedback the microprocessor directly controls the power level to the pump (6) thus adjusting the airflow to the cells to prevent bottoming or to rung at a minimum pressure. The pressure pad (1) is segmented into a heel section, upper leg section, torso section, and a head section. The heel, head and upper leg sections are maintained at a lower pressure P1 and the torso section at a higher pressure P2. A control module (50) to control the flow in the segments is provided inside the pressure pad (1). The pressure pad (1) can be an alternating or static pad.
