A device for collecting samples of body fluids is described which has at least one lancet, comprising a lancet body and a tip. The device is characterized in that the lancet includes a structure of changed stiffness, which can also be referred to as a kinked area. This structure preferably has reduced stiffness compared to the rest of the lancet body, such that the lancet is preferably kinked in this area under the action of a force. As this happens, the tip is changed in orientation with respect to the rest of the lancet body. This change of orientation is preferably out of the plane of the lancet body.
