摘要

The device has a closed system made of flexible gas and liquid impermeable material, where the system is filled with the gas and/or the liquid. The volume of the system is segmented or individual volume is included by the system for exercising locally different surface pressures on the system by variation of the pressure in the segments or the individual volume. The pressure in the segments or the individual volume is adjusted by a pump and a valve system, where the pressure detection takes place by a motor current of the pump.
