Abstract: The suction cup is placed in sealing contact on the anterior side of the torso. A partial vacuum can be applied to the body by the suction cup. The suction cup is composed at least in part of soft elastic materials. It is provided with inner flanks that flare toward the body when under atmospheric pressure. The suction cup bears with lateral body-fitting portions on each side of the sternum, with an upper body-fitting portion on the upper region of the sternum and with a lower body-fitting on the lower region or below the sternum. The deformability of the suction cup varies over its circumference. At least the upper, lower or one of the lateral body-fitting portions have different deformabilities.
