Abstract

The present invention relates to a compression device for stimulating the efflux of a body fluid from a body part. The device has a compression unit with a pressure-application region made of a deformable material, the region being formed to generate a repulsive force between the body part and the compression unit. The repulsive force passes through a force maximum then decreases to serve as an indication that the body part is guided sufficiently firmly and far enough onto the compression unit.
